Childhood obesity is on the rise and is quickly becoming a nationwide issue. There has been limited research when it comes to the relationship between the family as a unit as a predictor of the child's weight. The purpose of this study was to assess family factors that may predict childhood obesity. Participants consisted of one hundred and twenty-eight parents of preschool age children in Illinois. The Self-Report Family Inventory was used, along with the child's BMI and other family characteristics. The independent variables that were looked at as factors in predicting childhood obesity were family health/competence, family conflict, family cohesion, family leadership, and family emotional expressiveness, maternal employment, ethnicity, and socioeconomic status. The dependent variable used was children's BMI. Family leadership/parenting styles and family expressiveness showed significant results in relation to BMI. Possible explanations for findings, limitations, and implications are discussed.
