Overweight and obesity prevalence rates among youth in the Carolinas.

Overweight and obesity have become major public health concerns in the United States, reaching epidemic proportions among adults and children in recent years. According to the most recent national surveys, American adults have experienced a 50% increase in the prevalence of overweight and obesity. Moreover, an alarming 100% increase has been observed among children and adolescents since the 1970s. To assess the status of overweight and obesity prevalence among youth in the Carolinas, weight, height, waist, and hip circumferences were monitored during routine cholesterol screenings among 11- to 14-year-olds in two school districts. Of the twelve hundred students screened, 32.4% percent were overweight and 16.4% were obese, exceeding national averages of 22% and 11%, respectively. The overweight and obesity prevalence rates were even more dramatic when broken down by gender and ethnic/racial groups. For instance, 54% of black girls and 45% of black boys were overweight, and better than half of these students were obese. Overweight and obesity prevalence rates among black girls were nearly twice the rates observed for white girls. Ethnic differences in percentage of overweight and obese boys were not as great as those observed among girls. A number of factors may contribute to the unprecedented levels of overweight and obesity observed among American youth, including physical inactivity, poor nutritional habits (i.e., high-fat meals and snacks, and super-sizing), economic, and social factors. Consequently, the coordinated efforts of physicians, school nurses, teachers, parents, and students will be necessary to effectively address the growing problem of childhood obesity.
