Effects of parenting style and parent-related weight and diet on adolescent weight status.

OBJECTIVE

This study examined the interaction between parental limit setting of sedentary behaviors and health factors (weight status, physical activity [PA], fruit and vegetable [FV] intake) on standardized body mass index (zBMI) in African American adolescents.

METHODS

Data were from 67 parent-adolescent dyads. Parental limit setting, PA and FV intake were assessed via self-report, and objective height and weight measurements were collected.

RESULTS

Regressions examined the interaction between parental limit setting and BMI, PA, FV intake on adolescent zBMI. The model for parent BMI and FV intake accounted for 31% of the variance in adolescent zBMI. A significant interaction for parent BMI by limit setting showed that as parental BMI increased, higher (vs. lower) limit setting was associated with lower adolescent zBMI. Higher parent FV consumption was associated with lower adolescent zBMI.

CONCLUSION

Future interventions should integrate parent limit setting and target parent fruit and vegetable intake for obesity prevention in underserved adolescents.
