Objectives: To assess the correlates of parental classification of adolescent weight status. Methods: Measured adolescent weight status was compared to parent self-report perception data (n 374 dyads) using multivariate analyses with interactions to identify characteristics associated with inaccurate parent classification of adolescent weight status. Results: Adolescent weight status was underestimated by 31 of parents. College-educated parents were more likely to underestimate the weight of their male adolescents (OR1.95) and overweight adolescents (OR4.0). Non-college-educated parents were 8.92 times as likely to misclassify overweight adolescents, regardless of the sex of the child. Conclusions: Parental perception may play a role in supporting adolescent's healthy weight-related behaviors.
