type2diabetesAs you probably are aware, the number of Americans who develop Type II diabetes has steadily increased over the past two decades. Many people have attributed the typical American diet to the increase, but now researchers from Lund University in Sweden are proclaiming that a poor diet isn't the only contributing factor to the development of Type II diabetes--a lack of sleep can also be a contributing factor, if you have the right combination of genes. Read the original article (link below) to find out about the complex interactions between the hormone melatonin, sleep and blood sugar levels. It really is interesting, and raises many questions for further research, such as do people who regularly deprive themselves of sleep, regardless of genomic composition, have a higher risk of developing type II diabetes? I am thinking specifically of my students when I ask this question, as AP and IB kids tend not to sleep a whole lot. Does this behavior put you at higher risk for developing this disease, regardless of how well you eat or how old you are?

Reading the article piqued my interest for a couple of reasons: I am a type II diabetic, and the sleep I get on a regular basis is not nearly what it should be. But did my lack of sleep directly contribute to my developing diabetes? In my opinion, probably, but it was not the only contributing factor (I know this for a fact!). Could I generalize the results of this study to fit my own personal situation? That's where this article becomes interesting.


11

You see, the researchers only studied people of European descent. Now, I am not of full European descent--my mother's family is part Apache Indian (my paternal grandfather was Apache), and my father's
family is a mixed bag of Irish and Mexican descent. I like to say I am a Heinz 57 varieties human being! It is well-known that Hispanics have a high rate of type II diabetes, as do African-Americans. So why were these two ethnic groups left out of this study? It should be noted that Sharon Moalem, author of the bestselling book Survival of the Sickest, has postulated that diabetes (type 1) developed as a response to subfreezing temperatures. And where did these people afflicted with Type 1 live? Yep, Europe.

So the study raises some interesting questions about experimental design, like:


18

Were people screened for Type 1 diabetes in any way? Was a thorough family history taken for each participant? Why were certain ethnic groups excluded? Was the group of people studied of a particular gender? Does the fact that this study only included certain people bias it in any way, and if so, how? Can a truly unbiased study on this same topic be designed, and how?

Melyssa Son on paragraph 1:

I think that sleep could very likely be a contributing factor of type II diabetes. My grandmother, who has several health issues, never slept more than 5 hours at a time for most of her life, and her doctor believes that her health issues were caused by long-term lack of sleep.

Jen on whole page :

This particular experiment seems to have, like all experiments, limitations and errors. It could definitely use some suggestions for further improvement in its design. Instead of resorting to a narrow focus on people of European descent, this range needs to be broadened to people of all descents, as well as grouped ages. This way, more comparative data can be collected and investigated.

December 8, 2008 11:47 am
Andrea Grbavac :

I agree with Jen’s idea of conducting an experiment with a variety of diverse groups of people. Further experimentation should be conducted using a random sample. The results could then be arranged into groups of data derived from samples of various ages, ethnicities, and genders to draw conclusions by comparing and contrasting the results from each group. This would be a more representative sample of the population than a sample of only individuals of European descent.

December 11, 2008 1:42 pm
Gabrielle on paragraph 1:

Well age and unhealthy eating cannot help. It is logical that not sleeping would effect your health. It seems that the best thing to do to prevent type 2 diabetes is to lead the healthiest life style. Don’t just think that just fixing one area is going ot fix everything.

December 8, 2008 1:03 pm
Kelly Doyle on whole page :

Even if sleep does affect sugar levels in the body, it won’t affect it enough to really decide whether you have diabetes or not. I guess it could be the straw that breaks the camel’s back, but it definitly won’t be the majority of the load the camel’s carrying.
They can inform people that sleep decreases the chance you’ll become diabetic, but I doubt that’ll stop people from staying up. Besides, everyone already knows that sleep is good for you. That’s a no brainer.
And maybe the people who end up getting diabetes are just staying up later to have desert?

December 8, 2008 1:56 pm
Ellie Rosentel :

Your comment made me laugh, though I think it is a great insight. I know when I stay up late, I tend to eat icecream. I have also heard of studies that conclude that sleep deprivation leads to sugar cravings because it is an easy form of energy for the body. Perhaps it is what the lack of sleep leads to, rather than the lack of sleep itself, that increases the chance of diabetes.

December 11, 2008 2:41 pm
Priscilla Quach :

I’d have to agree and say your comment is probably the funniest thing I’ve read on here. You’ve got a good point when you said that no sleep is obviously going to be bad for you, but at the same time no one really cares. That reminds me of an episode of House that I just watched and they were talking about how you can only live for 10 or 11 days without sleep. I mean since when you’re asleep your body is resting and restoring itself, wouldn’t it make sense that a lack of sleep would through your whole system out of wack? I don’t know. I feel like all these discoveries are telling me how I should live my life.

December 13, 2008 10:43 pm
Jen on paragraph 2:

The article explaining the genetic link between the lack of sleep and type II diabetes reveals quite the domino effect – relationships that go beyond obvious information. Basically, the lack of shut-eye can change blood sugar levels, essentially interfering with human molecular timekeepers. Disordered sleep can then lead to intertwined pathologies, all due to the close connection between melatonin and glucose levels. The article basically concludes with pointing out the need for further studies in this area of health science.

December 8, 2008 5:40 pm
Brandon Pekarek on paragraph 5:

I think that while this study is very enlightening and helpful it can come across as bias in some ways. The fact that only people of European descent were studied is the thing that really starts to make me doubt the results. If only one group of people in a specific location were studied then what’s to say that anyone else any where else will produce the same results. For all we know, the air quality in Europe may also cause diabetes in certain people. The things that could determine an outcome of an experiment need to be limited to insure accuracy. The list of variables is very long and shows that more testing and experimentation is needed.

December 8, 2008 7:25 pm

I agree, Type 2 diabetes can be caused depending on the environment you live in. Other than air quiality, the altitude can also be another effect. Depending on different altitudes it may be harder or easier to gain weight. This would tie with the effect that obesity is a risk factor for diabetes. Heredity also plays a part in causing diabetes. Therefore, by just having this study of those of European descent really narrows down the results as to not being accurate for most people.

Krishan Gupta on whole page :

The fact that the circadian rhythms and biological clocks within us are directly correlated with the blood sugar levels clearly indicates our inner tickings have much more to do with each other than we could imagine. the best example from the article was the idea that melotonin receptors on insulin-secreting cells makes it more likely that the receptor is directly controlling the output of insulin.

December 8, 2008 8:20 pm
Krishan Gupta on paragraph 5:

it is important to know that a lack of sleep can contribute to a low insulin level and high blood sugar level. However, it is also important to know that numerous factors, such as race or gender, can play a huge role in determining whether or not insulin production will be inhibited. For example, a culture may be prone to eat starchy, sugary foods and already be at risk of high blood sugar levels.

December 8, 2008 8:36 pm
Paul Nguyen on paragraph 1:

This is really interesting to find out that a lack of sleep could be a factor for developing type 2 diabetes. It is true that sleep is important but if this proves to be true, then it could become even more of a emphasis. I believe that while depriving yourself of sleep isn’t the smartest or healthiest thing to do, it doesn’t put you at a higher risk of developing diabetes. I still think it is a minuscule factor in sugar levels to make an impact.

December 9, 2008 2:20 pm
kierra on whole page :

Maybe they were studying only those of European descent because previous research had been done on Mexican and Africa descendants. However this exclusion is a major limitation in the fact that many people have mixed ethnicities. As for diabetes i think a lack of sleep might increase stress with a combination of poor eating habits has already proven to lead to being overweight, which could become the basis of diabetes.

December 9, 2008 6:18 pm
kierra on paragraph 1:

In an experience with my mother who developed diabetes due to pregnancy i noticed how she barely slept due to stress at work and the demands of a new marriage. She also ate a lot of sweets and let go of her good eating habits. It seems like these habits go hand in hand with disease.

December 9, 2008 6:20 pm
David Kern on whole page :

The summary of what you wrote on the orginal article says “…a lack of sleep can also be a contributing factor, if you have the right combination of genes”. This doesn’t mean that all sleep deprived people will delevope Type II diabetes, but I am led to believe that it is referring to that only a significantly increased number will delevope Type II diabetes.

December 9, 2008 9:13 pm
Sara Betterton on paragraph 1:

Well, my father is a type two diabetic- a condition he did not develop until his late thirties. He was diagnosed in 2003 before our summer vacation. Dad was always a pretty healthy guy- 6′ 5″, muscular college football player. But he had a penchant for Dr. Pepper and Oreos. And as his engineering career progressed he got less and less sleep and had less and less time to eat proper, healthy meals (something he is fighting now, still). Now he and I both know he doesn’t get enough sleep or enough “rabbit food”. And we have noticed that his blood sugar is much better when he gets more sleep. I personally do not think that we are at a higher risk for type two because of our lack of sleep, but if we don’t eat right and take care of ourselves the way we should in the first place, sleep may drastically change any medical conditions we may develop.

December 9, 2008 9:15 pm
Christiana Kittelson :

I agree with Sarah B, which after reading the rest of the column, supports my hypothesis and opinion that lack of sleep enables the factor of weight gain, and also vice versa. Unhealthy foods contain sugar, fat, and caffeine, a recipe for high blood pressure, high pulse, and not enough REM. Thus food is the main link between, well all most every factor of diabetes type 2: its a vicious cycle. So should scientists ask what contributes to weight gain and kill, well about one million birds with one stone?

December 10, 2008 9:23 pm
Nadeem "Biolo-G" Anvari on paragraph 1:

Well the question that is asked here is if people who deprive themselves of sleep have a higher risk of developing type II diabetes, and i would have to agree. Studies in the past have shown that sleep deprivation causes many health problems, why not add type II diabetes to the list. But like Gabrielle said, we can’t just sleep 12 hours a day and consume pounds of chocolate covered lays potato chips with sprinkles, candy corn, cranberry filled marshmellows, and caramel sour patch kids on the side. We must maintain a healthy lifestyle and continue to monitor our diets. If sleep deprivation truly plays a part in diagnosing type II diabetes, then it most likely has a minimal role compared to such factors as genomic composition and a healthy diet. But, do not fear my fellow classmates, I have a solution. If we all can come together in a collective effort in eating only celery and eggs and sleeping 12 hours a day, we shall overcome this vicious disease and live a healthy life. Of course if diabetes runs in your family, then you’re out of luck. Thank you and good night.

December 9, 2008 9:26 pm
jiaxi :

This solution suggested by nadeem would work if everyone had the luxury of sleeping 12 hours a day and eating only celery + eggs. However, it would not be possible due to the busy lives we pursue, as I am certain that anybody would sacrifice sleep for even the most monotonous things like watching the tonight show or surfing the internet… It is human nature to stay out of boredom, and what could be more boring than sleeping? In order to prevent diabetes, I think we should educate people living in America about the harmful effects of diabetes which include and not just limited to nerve damages, eye damage, heart damage, limbs damage, cardiovascular damage, etc…

December 10, 2008 10:59 pm

That is a good point about neglecting sleep because it is boring. We tend to stay up doing useless things like watching TV or going on the Internet. It would be hard to break habits like these. Even if we were educated about the risks of diabetes, I don’t think many people would change their lifestyle. Our society tends not to act until there is already a problem.

December 11, 2008 1:28 pm
Paul Nguyen :

I think that I once heard that sleeping too much actually is not good for you. Usually isn’t 6-8 hours good? I think Nadeem’s solution to our sleep deprivation could actually come back to harm us. No offense Nadeem. I still think that proper eating and exercise with the extra attention to the amount of sleep people have could help prevent this disease.

December 11, 2008 10:05 pm
Victoria Vish on whole page :

It does seem like the results of the experiment could have slight error because the the testing subjects. It probably would have been best to perform random sampling entire populations to prevent the possibility of correlating the findings with just one particular ethinicity or gender. However, I’ve read similar articles that also claim sleep deprivation is related to weight-gain, which can thereby trigger type two diabetes

December 9, 2008 9:28 pm
Glenn-Eric Bautista on paragraph 5:

Any experiment that doesn’t not include every possible subject is biased, however including so many people creates lots of time problems. To do experiments on so many people in so many places is impossible. However, if an experiment is only conducted with such a narrow study group such as one gender, one ethnicity, or one area/environment, than the results are very biased and in many cases can nnot be accurate enough for other ethnicities, areas, or any other groups of people. There are simply way to many variables that can be different between environments, habits, ethnicity/genes, and many more that can affect results.

December 10, 2008 9:10 am

I think this study is a good starting place. It is okay to focus on a specific group of people to make the experiment feasible. But if a pattern arises, further research should be done with other ethnic groups and genders to make sure the conclusion was a rule not an exception.

December 11, 2008 1:12 pm
Rebecca on whole page :

I agree with Victoria, they should have done a random sampling this would have produced a better sample group. I wonder if the amount of sleep a person gets can be associated with their lifestyle and possibly eating habits, as well as amount of stress. Sleep is an important part of health and during sleep the body has a chance to rebuild and get back on track, without this opportunity health is obviously at risk.

December 10, 2008 6:00 pm
Alan Bjerke on paragraph 5:

I personally believe the researchers of this study were so vague because they might have not discovered what they wanted to prove and only published the results that backed their theory considering that they leave out specific details that even a high school student would normally take into consideration. Given enough time and effort someone unbiased could try to perform a study on this same topic and obtain truly unbiased results if all of the variables are considered, tested, and published.

December 10, 2008 8:37 pm
Christiana Kittelson on paragraph 1:

Let me answer this before I read the rest of the article. Yes us AP/IB kids don’t get enough sleep, and if that was the connection to diabetes type II, then we would have a lot of hard working kids with insulin disorders, but I must ask the question if the link between diabetes and lack of sleep is that lack of sleep attributes to weight gain which is one of the factors of diabetes type 2. So in my opinion, lack of sleep certainly doesn’t help the disease but it isn’t in direct link to diabetes, it just may enable one of the factors.

December 10, 2008 9:14 pm
jiaxi on whole page :

designing an experiment for factors which contribute to diabetes II is complex. first of all, we have to ask ourselves whether diabetes II comes from nature or nurture. Do our genes play a more significant role or our the in our daily lives? Or could it perhaps be a combination of the two? So many extraneous variables fall into research of diabetes II that it would be impossible to single out one single factor of the cause of this complex disease, I don’t think we will ever find one single cause for diabetes, so designing this experiment is virtually impossible. For now though, we should thank whoever invented metformin…

December 10, 2008 10:46 pm
jiaxi on paragraph 4:

the most important thing to experimental design is the possibility for other scientist in your field to repeat what you have discovered. this experiment obviously would be too unethical to be conducted on humans, so that leaves us with rats, monkeys, and dogs, etc… We then will have to give simulate the cause of diabetes and add the extra ingredient of deprived sleep to the experimental group and set up a control of a group of animals which receive a normal amount of sleep. The interesting part is giving these animals diabetes, as there is no consistent way of contracting or giving diabetes…How will we isolate the independent variable of deprivation of sleep from the rest of the causes of diabetes II? And can the dearth of sleep alone cause diabetes II?

December 10, 2008 11:12 pm
Andrea Grbavac on paragraph 1:

I found the relationship between melatonin and blood sugar levels interesting.
Since melatonin is sold over-the-counter in the form of sleeping pills, it’s often used to alleviate people of jet lag and insomnia. In the US, the hormone is classified as a dietary supplement; Therefore, it is not subject to FDA approval. Though it has generally been deemed non-toxic and safe, just how safe is a substance that most likely promotes type II diabetes? Does this study support the idea that it is risky to take sleeping pills containing the hormone? Additional research should be conducted to reveal more information about the safety of melatonin.

December 11, 2008 1:26 pm
Andrea Grbavac on paragraph 5:

Since certain foods contain melatonin, including, for instance, oats, sweet corn, and rice, could consumption of such foods on a daily basis over a long period of time possibly contribute to high blood sugar levels, which would thus translate into a higher risk of developing type II diabetes?

If this is true, a diet consisting of foods rich in melatonin may have possibly been an extraneous or even confounding variable in the study.

December 11, 2008 1:46 pm
Ellie Rosentel on paragraph 1:

I believe that a lack of sleep does put anyone at a higher risk of pretty much any disease. Sleep is good for you and necessary for life. Period. I do, however, really like this article, because now I can give a really good excuse for why I didn’t do my english homework. I wonder if, generations from now, there will be laws enacted to keep teachers from assigning too much homework because their students are not sleeping enough, or if employers cannot have the same person close and then open the next day. With this world getting more politically correct by the hour, I wouldn’t doubt it.

December 11, 2008 2:57 pm
Jon-Michael Evans on paragraph 1:

I find it very interesting that sleep deprevation could cause diabetes. My sister has type two diabetes and she also has four children. Before the children were born she had no signs of diabetes and now that she stays up late preparing and cleaning she has diabetes not to mention the fact its getting worse. I think I might want to direct her attention to this article.

December 11, 2008 3:51 pm
Jon-Michael Evans on paragraph 3:

I’m extremely curious to find out exactly how diabetes could be a response to sufreezing temperatures. Could it be that, for lack of a better phrase, diabetes often makes you gain wait and fat insulates you from cold weather? But… how would the cells know to “develope it”.

December 11, 2008 4:03 pm
Victoria Vish on whole page :

Jiaxi makes a good point…there are a lot of contributing factors to type II diabetes. But the fact the sleep deprivation could be a newly found cause is not entirely impossible to research. It would take a great number of subjects to experiment on in order to make an accurate conclusion, but it could be done.

December 11, 2008 5:20 pm
Lesly Ogden on paragraph 1:

I was talking with John-Michael and Ellie a little while ago, and we had decided that it wasn’t just the lack of sleep, but what people do when they don’t sleep. When we stay up late or can’t fall asleep, we tend to get cravings. Mostly sugary things, because it’s a quick form of energy. So, if people that can’t sleep do that over a long period of time, wouldn’t it make sense that they would maybe develop Type II Diabetes? Also, if we consciously make the decision to not eat sugary foods while we are up, and instead choose to eat healthier things, would the percentage of Americans who develop Type II Diabetes decrease?

December 11, 2008 5:46 pm
Lesly Ogden on paragraph 3:

Heinz 57 varieties human being here, too! Though, it is quite interesting knowing that the researchers only studied people of European descent. I wonder what their findings would be if they chose to compare their original studies with those of Mexican descent, Native American descent, and so on and so forth. Would a factor of their Type II Diabetes include lack of sleep, or what we eat when we can’t sleep?

December 11, 2008 5:50 pm
Lesly Ogden on paragraph 5:

I don’t know… many people in America have some sort of European ancestry. Maybe the researchers wanted to know what factors brought about Type II Diabetes in Europeans because many people are related to them in some way. I’m just wondering here, because although I am a Heinz 57 varieties human being, most of my ancestry originates in Europe. Just a thought.

December 11, 2008 5:53 pm
Jennifer Abohosh on paragraph 1:

I was talking to a friend who lived in California and she said that her school actually delayed classes on Wednesdays a few hours so the kids could get more sleep. They were saying that to live a healthy lifestyle, more affective for learning that the public school students needed a few extra sleep hours in the middle of the week. This sounds like a plan to me! If indeed lack of sleep does cause Type II diabetes in a significant amount of people, as well as other diseases, then, as a student, I believe the “midweek sleep” would be very beneficial to my health and my brains efficiency to learn!

December 11, 2008 7:19 pm
Jennifer Abohosh on paragraph 5:

It would be interesting to see the answers to these questions and after finding out a few more details my view on the experiment would likely change. It would be interesting to see the study done with a variety of ethnicities and genders to compare the data to that of this article.

December 11, 2008 7:40 pm
Steven Richards on paragraph 1:

It is my assumption that lack of sleep is in fact a contributing factor the type 2 diabetes but is it not also a supposed contributing factor for many other health complications? Lack of sleep leads to increased stress levels which then leads to increased susceptibility to viruses and other malicious germs of the sort due to the deprivation of energy from the body, especially the immune system. In essence it is just better to sleep more and there in worry less about health.

December 11, 2008 8:51 pm
Steven Richards on paragraph 5:

Of course this study was biased in the way that they only studied subjects of European descent. It states that there is a possibility of type 1 diabetes being an evolved adaptation to civilizations living in subfreezing temperatures, pinpointed to Europe for the most part. With this little note of information it brings up the idea that possibly genetic factors linked to heritage are linked to diabetes in people. Thus, to conduct an unbiased case study would further contribute to the accuracy of the findings.

December 11, 2008 9:02 pm
Peter Ngo on whole page :

Considering this is just now being discovered, how much is sleep deprivation is really a contributing factor of type II diabetes? It’s easy to question how much it actually influences it if it’s just now being considered as a cause.

December 12, 2008 9:48 am
Glenn-Eric Bautista on paragraph 1:

I think that sleep deprivation and the food we eat are large contributing factors to health. During sleep our body does much needed reparis and other important things that are very important to one’s health. Also, food is very important. For your body to function it has to have the right materials/building blocks to function correctly. If you don’t have enough of certain vitamins or protein than it makes it very hard to function and can even cause damage. Furthermore what do you do when you get sick, you sleep a lot. Obviously, sleep is very important to us. However, I don’t think it can be related to every illness, but it can definetly be detrimental to you health.

December 12, 2008 9:50 am
David Kern on paragraph 1:

Type II Diabetes has been shown to be caused by lack of sleep in various cases, but how was this concluded? Who was the control group and who was the variable group? How much sleep did each group received during the trial period? These are just some of my questions that I tend to think about while reading the first paragraph.

December 12, 2008 11:12 am
Parker B. on paragraph 3:

For this study to be conducted without including these two heavily affected ethnic groups makes it very inaccurate in relation to the United States. To have a more accurate study, it needs to be redone here in America to see more thoroughly the statistics and effects of Type II Diabetes on the various ethnicities of America. A statistic for us here is: for every six white Americans who have diabetes, 10 African Americans have diabetes. That’s a pretty big part that needs to be included.

December 12, 2008 3:10 pm
Parker B. on paragraph 5:

The fact that many different ethnic groups were left out of this study biases the results an extreme amount. Also, perhaps an unequal amount of females and males were present which could also sway the results. Conducting this study in Europe does not mean that they included all the groups needed to make this an unbiased and accurate study.

December 12, 2008 3:15 pm
Austin Henke- 09 :

I am going to defend these scientists from the lovely game of 20 questions. They need their sleep too. Maybe this is the first step in discovering what occurs in diabetes. Maybe now they are able to expand their knowledge. Maybe spilting up, all with the same common knowledge, to discover all the factors that contribute to all differencies in diabietes exponentially. Or then again maybe they just got tired.

December 14, 2008 9:46 am
Alicia Crosswhite on whole page :

I really found this post interesting. I know this is just another reiteration, but I do agree that this “possible” finding could be very concrete. Although scientist and a variety of studies contradict one another on the amount of sleep a person needs each night, especially teenagers, but most everyone knows that sleep is necessary for a healthy being. Sleep deprivation does not only lead to different emotionally linked diseases, as we have been told many times by these multiple studies. I do think it is interesting that they only tested European subjects for this study. Widening the experimental and controls groups could widen the evidence linked to this proclamation.

December 12, 2008 3:44 pm
Tiffany on whole page :

That does not sound good. It is easier said than done for humans to follow the pyramid of hale and hearty foods on a daily basis because it is basically easier to go to a fast food restaurant and devour their food because it is economical, one do not have to go to the hassle of preparing food, and it simply taste better! If reduced sleep will increase chances of obtaining diabetes, then unluckily I have to a great extent increased by chances because I have a family history of diabetes and once in a blue moon I get eight hours sleep.

December 12, 2008 4:56 pm
Alyssa Munk on paragraph 2:

It does seem difficult to contribute the cause of type II diabetes to sleep deprivation when many other factors could cause the disease. Although in the article it describes melatonin, a regulator of sleep, as a link between glucose levels and diabetes, I agree with Jen that more studies should be conducted before such as conclusion can be drawn.

December 12, 2008 9:06 pm
Alyssa Munk on paragraph 1:

I agree with Christiana’s comment. There is no way that AP and IB kids are getting enough sleep every night. I believe the healthy number of hours for teenagers is somewhere between 8 and 10 hours. Does anyone know the number? I personally do not get much sleep and think this discovery is shocking. However, I think other factors such as your diet probably play a major role in developing type II diabetes.

December 12, 2008 9:11 pm
Alyssa Munk on paragraph 3:

I agree with Parker and Lesley’s comments. How can these results be considered accurate if only Europeans have been studied? It seems logical to research the effects of lack of sleep on type II diabetes across all different ethnic backgrounds. Also different cultures and tribes should be studied around the world in order to compare the results and draw conclusions. This is good way for the accuracy of these findings to be proven.

December 12, 2008 9:22 pm
Santoshi Ramachandran on paragraph 1:

You should always do everything in moderation and I think this concept definitely applies here. We need to find a balance between too much and not enough sleep. Like many have said before, I don’t believe that sleep deprivation is the main cause of diabetes and that it might be just one part of a whole series of links which cause diabetes. Now that we have found this link, hopefully, we can start changing our ways to impact our health for the better. I thought that Jennifer A.’s solution of the “midweek sleep” is one of the best solutions I’ve heard and I am all for that solution to be initiated here in Texas too!

December 12, 2008 10:23 pm
Santoshi Ramachandran on whole page :

I agree with everyone here on the fact that the research would have been so much more irrefutable if they had a better sampling of people. By only examining people from European descent it could have skewed the results. But then again this is only the beginning of the vast array of research which should result from this study. I believe that sleep deprivation and the risks associated with it are important enough for us to spend more time perfecting this study. By solidifying the results, (with better sampling) the research might help aid in teaching people about the major risks associated with sleep deprivation.

December 12, 2008 10:40 pm
camden on paragraph 1:

The article indicated that people that deprive themselves of sleep have a higher risk of developing type II diabetes. However, the article did not show the relationship between age, sleep, and blood sugar levels. Older people, like my grandparents, only sleep very few hours each day, which would mean that they would have a higher chance of developing type II diabetes. However, I think that sleep is not the only factor that contributes to type II diabetes in older people because as people get older they tend to have more health issues in general.

camden on paragraph 5:

I do think that this study is biased because it only included people of European descent. I would think that the results could vary between different ethic groups because of the diet and quality of living. However, it could be very challenging to include participants of all of the other possible descents.

Rebecca on paragraph 1:

I think there is a reoccuring theme in all of the posts, that sleep is an important factor but it is a clue to the style of life that is being persued. If you cannot find enough time to sleep you probably have too much on your plate and need to relax, and also probably arn’t eating right because of lack of time. Eating healthy takes more time and effort something people arn’t willing to do when it puts a hitch in their fast paced lifestyle. So overall with more health conscious behavior maybe more sleep could occur and type 2 diabetes wouldn’t be as common.

Christina on paragraph 1:

while sleep may play a minor role in causing type 2 diabetes, it is all the other known factors that contribute mainly to the cause. The sleep factor should definitely be tested more before they conclude that sleep deprivation could be one of the major causes. The multitude of people who are lacking sleep are much more prone to get diabetes type 2? i find that hard to believe, so research and testing should continue in this area.

Ashley Ramdeen on paragraph 5:

I don’t think that this article’s research is credible or accurate. Leaving out factors such as genetics, gender, and ethinic groups when dealing with diabetes is almost as useless as just guessing. I see a potential in the idea of sleep connected to diabetes, BUT in order to be truly unbiased, all factors must be taken into consideration.

Mayra Ramirez on paragraph 5:

Even though this study was scientifically insightful, it was rather biased as it only pertained to subjects of European descent. Maybe the researchers focused on the people of Europe because most of us, as evidenced by the words “Eurasian” and “Eurafrican”, all somehow link back to the place where civilization seemed to begin, making it more convenient. In order to avoid a study producing skewed results, a sample from a distinct population, considering gender, race, and ethnicity, must be taken in which each person has an equal chance of being selected. Other varaibles must be considered, including family history and the levels of blood sugar , in order to produce a thorough and accurate experiment.

Jimmy Pi on paragraph 3:

I wonder what is the percentile of people who are affected by this of asian descent. I also wonder whether or not the location in which someone lives in also has a great impact on whether or not someone gets diabetes type II. However i believe this affects all of us because we tend to not get enough sleep according to our ages.

December 13, 2008 8:21 pm
Jimmy Pi on paragraph 5:

I believe that this study is yet to be completed but still needs further research to draw a conclusion because it excludes many factors that could have an impact on someone with type II diabetes. I believe this experiment is extremely biased because it limited its research only concerning certain factors.

Daniel DePaula on paragraph 1:

I agree with this. I think, in the right circumstances (I’m not trying to be pessimistic or anything), sleep deprivation could lead to developing Type II diabetes, as not enough sleep puts you in a stressful mood, and some people deal with stress by eating. It’s amazing to think how one small part of our lives can have such a tremendous impact on our future, and that something being as simple as getting enough sleep!

Daniel DePaula on paragraph 3:

The study left out multiple groups of people, and therefore, the study has a false conclusion in terms of the “average” human being. What they need to do is to do the study over, and take people 1) from around the globe, 2) of different ethnicities, and 3) men and women alike. This would help decipher what the average human’s chances are of developing/having Type II diabetes. Age could also be a factor, but if you decide to test every factor, then you might as well include the entire human population in the experiment, as we are all different in some way, if only slightly.

December 13, 2008 9:16 pm
Daniel DePaula on paragraph 5:

So many factors come into play when “experimenting” with humans. Age, genetics, lifestyle, emotions, gender, etc. All of these come into play when examining a single human being. Now, an alternative to an single, large unbiased study would be to do smaller, biased studies (maybe 1,000 people instead of 1,000,000 people in the larger study) and then, in order to get an average of the probability that you develop Type II diabetes, you take into account your gender, your age, your family history, your lifestyle, etc. and get an average of every group that you belong to.For example, a man of 54 who has no family history of Type II diabetes and lives a sedentary lifestyle would belong into the 4 groups of male, 50-60, no familial history of Type II diabetes, and sedentary lifestyle respectively. The average of these would give him his best view of his chances of developing Type II diabetes. This is just a start, though, as many factors affect us and thus the results. This would give us an idea of how likely we are to develop it; whether or not it says 1% or 99.9%, there is not guarantee that we will develop Type II diabetes or vice versa. That is the true mystery of the world that both surrounds us and lives within us.

Tyler Bevan on paragraph 1:

I get around 6 hours of sleep a night. Mostly due to the fact i have band, and i live in lucas, which means i have to get up at 5:45 or 6:30 every day depending on what’s going on. If my risks of type II diabetes are increased simply because i do not sleep enough i would be quite concerned. Then again, it would just be another part of life that you cannot really control, and thus the saying still stands strong, that there simply are not enough hours in the day.

Gabe on paragraph 1:

This type of research is so beneficial for people so they can actually recognize what they are doing to themselves and how much it is harming them. It’s just a real wake up call to people who get like 5 hours of sleep a day or even less. Everyday like that adds up and yea, something bad happens.

December 13, 2008 10:04 pm
Mayra Ramirez on paragraph 3:

The variable of ethnicity should have definitely been considered in this study, especially since certain groups are more prone to certain diseases, whether it be biologically or through their cultures’ expressed different ways of living contributing to Type II diabetes. But I wonder if our natural biological clock can act as a variable in this study. People in certain parts of the world seem to have different biological clocks as evidenced by the established time zones. While I may be typing right now, someone in China may be just waking up. Since only subjects of European descent were studied, only their specific sleep patterns were observed. If sleep is a contributing factor to Type II diabetes, the results would possibly be skewed.

Priscilla Quach on paragraph 5:

I think that even though this study was clearly bias, that doesn’t mean that we should totally discredit the findings. I mean you really can’t design a completely unbiased study that is representitive of the whole population because it’s impossible to control every confounding variable and prevent extraneous variables from affecting the experiment. I think what this experiment is, is a good first step. Obvioulsy more studies will need to be done to incorporate different ethnicities, age groups, backgrounds, etc. but this is still a good first step.

This predictions is very interesting and poses many questions with unknown answer currently at the moment because not enough research has been done. Type II diabetes is very common and is caused by many different reasons. I think that every person who gets it gets it for a different reason. An individuals lack of sleep or heritage could be a factor mixed in with the other causes of type II diabetes. It varies from person to person.

If we pull out the whole idea of diabetes in this conversation, then its common sense that sleep truly affects a persons body weight. Take bears for an example, during their hibernation period bears burn off pounds of fat from the food gorged during the pre-hibernation period, through sleep. Any stimuli that affect the body’s weight, regardless of how pointless it may seem, does affect the body internally as a whole. Its truly logical that health problems outside of mental status, can arise from lack of sleep; in this case diabetes occurred. Although it still doesn’t seem reasonable, it is still plausible that lack of sleep is a contributing factor to diabetes.

Andrew Kim on paragraph 3:

The reason that europeans were studies in this experiment could have a more pragmatic reason than a scientific one. that reason would be of course, money. as it is previously noted, the scientists who conducted this exam were from Sweden, and its hard to image Hispanics or Africans that live that north in Europe, for it is harder for both ethnic types to access those regions. therefore the study may have become biased unintentionally. Also, no matter what sample of people the scientists chose, there will always be a strong bias for every person is different. it is just amazing that they found a trend in diabetes 2 patients when the area is dominant in diabetes 1.

Gabe on paragraph 3:

Yeah I agree with it being not being actually related with the United States, maybe American researchers should conduct thier experiment on the U.S. and other countries should do the same. Then compare thier results with other countries. There are so many variables that go with health,

I mean, of course sleeping helps the body all the time. Connecting it with type II diabetes is a real challenge and pretty remarkable seeing how researchers did that.

“Experts say one of the most alluring sleep distractions is the 24-hour accessibility of the internet.”

“Diaries from the pre-electric-light Victorian era show adults slept nine to 10 hours a night with periods of rest changing with the seasons in line with sunrise and sunsets.”

People had more sleep in the past than … Today, technology is just creating alot of distractions that interrupt with our sleeping patterns.

like me.

victoria troncoso on paragraph 1:

I find this very interesting since many of my relatives have diabetes and also have trouble sleeping. However I think diet goes along with it, not sleeping and a bad diet could surely cause diabetes among many other things such as obesity as well.

Tiffany on paragraph 3:

This experiment would be more accurate if they tested their theory among all races. Maybe Europeans might have a higher chance of obtaining diabetes because of their race. This could have been more valid if they tested multiple races.

Tyler Bevan on paragraph 3:

That is an interesting idea for sure, but I’m not sure how true it is. If it appears more in hispanics and african-americans and they are descended from hotter places then Europeans then technically it wouldn’t really be a helpful thing. Then again europeans could of developed a grater natural resistance to it than other people, much like sharks with their cancer resistance abilities.

I can understand how a lack of sleep could develop unhealthy eating habits, incidently leading to the increase of americans with Type II diabetes. I know whenever I stay up late I tend to eat more, and I generally don’t drift towards the healthy foods. Overall I believe this experiment is very interesting and informative.

Seriously, Anything for more sleep. but maybe we should take this to the head man of the school. Less hours of school for more sleep anyone! Onward, I have wondered for a long time how much politics are in discoveries of the scientific nature. But this one although may be specific to European type II diabetes also should really take into account every other factor. Because the concept of sleep deprevation is a universal factor that should be studied in all diabetes studies.

Anudeep Dasaraju on paragraph 1:

It is fascinating that sleep has such an impact on our health. Quality sleep is essential for the body to heal, yet i had no idea that a lack of it could prove to have such adverse effects.

Devon on paragraph 1:

i believe this is correlated in the development of type II diabetes, because my grandfather has this condition and, back in the day, he worked his butt off all the time. sometimes working 18 hour shifts at a construction site. this means he did not get much sleep during this time period

December 14, 2008 10:59 am
Anudeep Dasaraju on whole page :

Although sleep might be a contributing factor, I think that the majority of the problem of type II diabetes comes from one’s diet. I have an uncle who is has type II diabetes, and has warned me that if you don’t eat properly that i will end up like him.
