One more point to show that “nature” doesn’t run the show when it comes to the health of our seedlings (or any of us, for that matter)… Last week Mark offered commentary on an analysis of twins and childhood obesity published in the American Journal of Clinical Nutrition, which had been picked up by MSNBC. Research out of the Johns Hopkins Bloomberg School of Public Health late last week highlights yet another environmental influence related to childhood obesity.
Their analysis of epidemiological studies found that with each additional hour of sleep, the risk of a child being overweight or obese dropped by 9 percent. Our analysis of the data shows a clear association between sleep duration and the risk for overweight or obesity in children. …The results of the analysis showed that children with the shortest sleep duration had a 92 percent higher risk of being overweight or obese compared to children with longer sleep duration. For children under age 5, shortest sleep duration meant less than 9 hours of sleep per day. For children ages 5 to 10 it meant less than 8 hours of sleep per day and less than 7 hours of sleep per day for children over 10. The association between increased sleep and reduced obesity risk was strongly associated with boys, but not in girls.
