Parents' stage of change for diet and physical activity: influence on childhood obesity.

Highly visible public health education efforts have resulted in increased awareness of the childhood obesity epidemic but not a related decline in the number of overweight children. The Transtheoretical Model was used to examine the associations among child risk factors, parent's knowledge of factors associated with childhood obesity and their access to healthy foods in their community and parent's stage of change (SOC) in making behavior changes to improve their child's diet and level of physical activity. Parents (n = 124) of children between 6-12 years of age were surveyed. Perceived weight of the child and the child's body mass index (BMI) were found to be associated with parent's SOC for food portions and dietary fats, yet this was not observed for the fruits and vegetables or physical activity domains. Food availability and parent's childhood obesity knowledge was not found to be associated with parent's SOC. This study provides evidence that intervention efforts that stress knowledge of the causes and harmful effects of being overweight may have limited effectiveness.
