As childhood obesity has increased, schools have struggled with their role in this epidemic. Parents with a school-age child in a suburban latchkey program were surveyed regarding their perceptions of childhood obesity, body mass index, and the school's role in prevention and treatment of obesity. More than 80% of participants identified inactivity, poor eating behavior, lack of parental control in what children eat, and eating too much as the main causes of childhood obesity. Parents preferred receiving information about their child's body mass index from the school via a letter from the school nurse. Participants agreed that physical education classes, as well as units on nutrition and weight control, should be present in schools. Parents also supported eliminating junk food machines and offering special low-calorie meals. By supporting these strategies, parents indicated that schools should have a role in childhood obesity. School nurses can advocate for parental preferences in their school district. (Contains 5 tables.)
