According to the Associated Press, a new study showed immigrant children of all backgrounds get even less vigorous exercise than their U.S.-born counterparts. Plenty of earlier evidence shows that U.S. children are pretty inactive. Almost 18 percent of foreign-born children with immigrant parents got no vigorous exercise on any days of the week, and 56 percent didn't participate in organized sports.
Given the obesity epidemic and immigrants accounting for about 13 percent of the U.S. population, the authors said it is important to know whether there are ethnic differences in physical activity and sedentary behaviors. The study appears in Monday's Archives of Pediatrics and Adolescent Medicine. It is based on 2003-04 telephone interviews with parents of children aged 6 to 17, including white, black, Hispanic and Asian immigrants.
Newer government advice recommends an hour of moderate-to-vigorous exercise most days. Just last month, a study found that fewer than a third of U.S. 15-year-olds got even that minimum amount.
