The effect of parental feeding behaviours and participation of children in organized sports/activities on child body mass index.

PURPOSE: In this cross-sectional descriptive study, we explored the relationship of parental feeding practices and child physical activity levels with measured body mass index (BMI) in a sample of 97 Ontario preschoolers.
METHODS: Child weight and height were measured; physical activity and sedentary behaviours were assessed by questionnaire. Preschoolers' parents used the Child Feeding Questionnaire to report their attitudes, concerns, and practices in relation to child feeding. Hierarchical multiple linear regression was used to determine relationships among variables.
RESULTS: Up to 25% of the preschoolers were overweight and/or obese. The regression model accounted for 53% of the variance in child BMI. Child BMI was predicted to be higher when parents had concerns about and perceived their children to be overweight, and when they felt responsible for what their children ate. Children's BMIs were predicted to be lower for those whose parents pressured them to eat and also for those who engaged in organized sports or activities.
CONCLUSIONS: This study suggests an association between BMI and parental perceptions, concerns, and practices related to child feeding and organized sports or activities. Public health initiatives related to healthy eating and/or obesity prevention should include a focus on parents of preschool-aged children with the home environment as a potential setting.
