title: Behavioral intervention reduces unhealthy eating behaviors in preschool children via a behavior card approach.
abstract: Many eating behaviors form in childhood, and some unhealthy behaviors may persist into adulthood and have potential impacts on people's health. This study evaluated the effectiveness of behavioral intervention in reducing consumption of Western fast food, sweetened beverages, fried food in preschool children, and changing parents' rewarding behaviors that encourage the consumption of the unhealthy foods. The research was a cluster randomized trial of seven kindergartens, involving 1138 children aged 3-6 years and their parents in Beijing, China. Parents and children allocated to the intervention group received two lectures and printed resources, including behavior cards, educational sheets. Children's behavior cards, applied with behavior-changing techniques, were used to intervene, and monitor behavior changes over time. Children in the control group just followed their usual health education curriculum in kindergartens. Intervention effects on food consumption behaviors were assessed by examining pre- and post-questionnaires. Of the 1138 children screened at baseline, 880 (77.3%) were measured at the end of the intervention period. The intervention lasted from March to June in 2010. The results showed that consumption of Western fast food, sweetened beverages, and fried food was decreased among the intervention group (P<0.001). Proportions of parents using Western fast food as rewards for their children were decreased (P=0.002). From March to June 2010, the frequency of each target behavior in children tended to decrease over the intervention period (P<0.001). Most parents favored regularly-delivered behavior cards or materials for behavioral intervention. In conclusion, the behavioral intervention encourages the healthier eating behaviors of children and reduces the parents' practice of using unhealthy foods as reward.
