In light of First Lady Michelle Obama’s initiative to combat childhood obesity, updated data shows that the rate of childhood obesity has, indeed, not declined. According to the most recent National Health and Nutrition Examination Survey (NHANES 2007-2008), the percentage of obese children, defined by BMI, has remained steady with nearly 17% of children having BMIs above the 95th percentile. This figure is identical to a decade ago when childhood obesity skyrocketed from approximately 5% to 17% between 1980 and 1999. Does this mean that the rate of childhood obesity has plateaued? Are we finally seeing the result of years of effort in attempting to curb childhood obesity? Perhaps, but one thing we know is that the rate has not declined and continued effort is much needed in order to reduce the future health burden obesity can confer on these children.

Today’s Daily Dose comes from the current issue of Neurology, the medical journal of the American Academy of Neurology. Researchers found, after following over 238 thousand women over the course of 40 years, that women who had a BMI of 30 or greater at the age of 18 had more than twice the risk of developing multiple sclerosis (MS), compared to women with a BMI between 18.5 and 20.9. “Our results suggest that weight during adolescence, rather than childhood or adulthood, is critical in determining the risk of MS,” said study author Kassandra Munger, ScD, of the Harvard School of Public Health. The study authors theorize the link between obesity and MS may be that obese women tend to have lower vitamin D levels (higher vitamin D levels are thought to reduce the risk of MS). In addition, fatty tissue can produce substances thought to affect immune and cellular function which may be associated with MS. [via Medical News Today]
