Parents' top concern is whether their kids are getting enough exercise, according to a new survey.
Researchers at the University of Michigan questioned more than 2,000 adults on the worries they have for their children's health.
Topping the list was not enough activity, followed by childhood obesity and tobacco use.
Other concerns included drug abuse, bullying and teen pregnancy.
Experts say kids who are active are not only leaner, but they perform better in school and have a better sense of well-being.
Hispanic adults were most concerned with their child's weight, while African American adults were most worried about smoking and tobacco use. African American and Hispanic adults both ranked STDs higher on their list of concerns than white adults.
