As obesity is on the rise researchers are looking for possible factors in the development of obesity in special groups including children and teens. Diet is a major factor, as is lack of exercise. But a recent review in the journal Archives of Disease in Childhood found some proof that lack of sleep may contribute to the increases in weight.
The review looked at numerous studies that assessed sleep quality and quantity in a variety of age groups from 30 month old toddlers to adults. Then factors that assess metabolic activity, physical activity, and weight were analyzed.
The study concluded that insufficient sleep can increase one's risk for becoming overweight or obese. This relationship could possibly be mediated by two hormones, ghrelin and leptin, which send signals to the brain about hunger and saiety.
One study included in the review found that insufficient sleep in 30 month old infants increased the likelihood that they would be overweight by age 7 years.
This review is especially striking when considering children and teenagers. In todays culture most children have a TV in their bedroom and participate in less physical activity. Both of these variables can be related to sleep, with kids not falling asleep as easily, getting less restful sleep becauase of TV, and not wanting to be active because they are too tired.
The authors recommend that TVs, computers, and other electronic devices be removed from childrens rooms to aid in more restful sleep.
