Parents with kids going back to school say their top concern is bullying.
A national poll on children's' health found that two-thirds of parents think that bullying, either online or in real life, is a big problem for kids going back to school.
Researchers at the University of Michigan Medical School surveyed over 15-hundred parents with kids under 18.
Parents were also concerned about internet safety and car accidents.
Responses varied with demographics.
African American parents said racial inequality was their big concern, and were more worried about school violence.
Hispanic parents also named stress as a big issue for their kids.
