drinking sweetened beverages has increased by more than 20 percent over the past decade (from 10.7 percent to 13.2 percent). Sweetened beverage consumption also increased at a faster rate among poor versus non-poor adolescents (67 percent versus 14 percent). Today, high school adolescents who live below the poverty line are more likely to be physically inactive and also more likely to skip breakfast, both of which are associated with excessive weight gain. The researchers did not see this same trend in adolescents aged 12-14. However, non-poor black adolescents in this age range were more likely to be overweight than their poor counterparts.

The researchers note that as more and more adolescents gain excessive weight, the associated consequences--type 2 diabetes, hypertension, sleep apnea, poor quality of life and morbidity in adulthood--will also increase.

"I believe that the trend in poverty and adolescent obesity can be reversed, if there is sustained public will to do so. While there is no silver bullet that will end this trend or the obesity epidemic in general, we know many of the major factors involved and we are beginning to do something about them," said Miech. "The recent, voluntary withdrawal of soft drinks from schools is a good step. We need to further develop and implement additional programs to improve adolescent nutrition and physical exercise, especially among the poor."
