Weight Gain And Sleep Patterns
Study Conducted To Establish a Relationship between Obesity and Sleep Patterns
The study conducted involved 52 people, out of which 25 were females. All of the subjects completed wrist actigraphy and food logs for 7 days. Of the sample, 56 percent were normal sleepers while 44 percent were light sleepers.
The light sleepers went to bed late, slept less and had awkward timings for meals. Moreover they consumed more calories in their dinner – mostly after 8:00 P.M. and ate fewer fruits and vegetables. Their intake of full-calorie soda was more as compared to other volunteers. They also had a higher average body mass index (BMI).
Study Conducted on the Sleeping patterns of Children and Obesity
Research conducted on children found that children sleep for nearly 8 hours irrespective of their weight categorization. The children who were obese were more likely to suffer from insomnia and were more active on weekends as compared to that on week days. While those who were overweight had mixed response and a mixed sleeping pattern emerged for them.
The research was conducted on 308 children in the age group of 4-10 years for nearly one week and their BMI was estimated. In the study the plasma levels of glucose, lipids, insulin and high sensitivity of C-reactive protein was measured for sample purpose. The results were astonishing. Nearly 29 percent of the children suffered from insomnia. Most of the kids took sleeping medications for proper sleep. Average BMI among the children suffering from sleep disturbances was elevated.
