This book is about a study that involved a cross-sectional examination of a group of 3rd graders to determine if correlates of child body mass index (BMI) existed. Children from the Jefferson County, Alabama area were recruited as a result of their participation in the Hi5+ dietary intervention project. The results from the study indicate that the prevalence of overweight children is high in this cohort. In addition, it appears that there are several predictors of child BMI in this group of children, including certain portions of the diet as well as several psycho-social variables. It is apparent that in light of the current obesity epidemic, determining potential correlates of increased child BMI is extremely important.
