The Effects Of Sleep On Blood Glucose Levels - 1162 Words

In laboratory studies of healthy young adults submitted to recurrent partial sleep restriction, marked alterations in glucose metabolism including decreased glucose tolerance and insulin sensitivity have been demonstrated (Spiegel et al. 2005). A pooled regression analysis in adults also suggests that a reduction in one hour of sleep per day would be associated with a 0.35 kg/m2 increase in BMI (Cappuccio et al. 2008). In Japan, a study of adolescents observed a dose-response relationship between short sleep durations and obesity (BMI 85th percentile for age and sex and a percentage body fat 25% for men or 30% for women) after controlling for age, sex, parental obesity, sexual maturation, physical activity, ethnicity, TV watching,†¦show more content†¦There is a lot of data of effect of physical exercise and eating on blood glucose levels and chances at Type II diabetes. However, there isn’t much much data on the effect of sleep on glucose levels and Type II diabetes development rates. More data is needed on the impact on amount of sleep and this experiment would do exactly that. 3. OUTLINE OF EXPERIMENT A. HYPOTHESIS AND VARIABLES The following is the hypothesis of our experiment: It is predicted that if people aged ten to eighteen years in America are allowed to only sleep less than eight hours consecutively a night, then they will have a higher mean blood sugar level than those who sleep eight hours or more consecutively a night. The independent variable of this experiment is the amount of sleep the children receive every night. This is operationalized by having two control groups, with children receiving 8 and 9 hours of sleep a night, respectively. Getting 8 to 9 hours of sleep a night is the recommended amount of sleep for children, so we predict that there will be no drastic changes to blood glucose levels. There will be two experimental groups, with children receiving 6 and 7 hours of sleep a night, respectively. The dependent variable is the effect on the blood sugar level. B. RESEARCH DESIGN AND FEASIBILITY This research project would be an example of explanatory research rather than exploratory or descriptive research. It is not descriptive
