found that mater lower maternal attachment and sensitivity, assessed objectively during the preschool years, were associated with higher prevalence of obesity during adolescene. Insecure parent attachment in childhood was also found to be associated with greater intake of high calorie food among children and adults. Level of bonding or closeness with a parent has also been shown to moderate the association between maternal-BMI and daughter-BMI and parental and adolescent weight-related behaviors. In contrast, using data from the National Longitudinal Study of Adolescent Health, Crossman and colleagues found that a higher degree of closeness with a parent was associated with greater risk for excess weight gain among males, but not females. Our study builds on these findings by using a broad definition of parent-adolescent relationship that includes numerous aspects of the rela tionship and by providing insight into how the father adolescent relationship that insight into how the father-adolescent relationship may be associated with adolescent weight and related behaviors, which was not explored in these existing studies
