Maternal Misconceptions of Weight Status among Nepean Adolescents

Published:November 20, 2012DOI:https://doi.org/10.1016/j.jand.2012.08.024

      Abstract

      Adolescence is characterized by rapid physical growth and sexual maturation. These changes may alter parents' beliefs about their adolescent's weight status. This study aimed to examine the changes between early and mid-adolescence in: (a) the accuracy of maternal perception regarding her adolescent's weight status, (b) the degree of maternal concern about her adolescent's weight status, and (c) the predictors of maternal misclassification of adolescent overweight as average weight. A secondary analysis of the longitudinal Nepean Study data was conducted. Participants were Australian, free-living 13-year-olds in 2002-2003 (n=347) followed up at age 15 years (n=279) and their mothers. Participants' body mass index (BMI) status (overweight, normal, or underweight) was calculated from measured height and weight. Maternal perceptions and concerns about adolescent's weight status were determined by items adapted from the Child Feeding Questionnaire. Sex-adjusted binary logistic regression models assessed potential predictors of maternal misclassification of adolescent overweight. Data were available on 224 adolescent-mother dyads. Approximately one fourth of mothers misclassified their adolescent's weight status, but this varied across groups (age 13 years [%]; age 15 years [%], respectively) underweight (75%; 70%), overweight (54%; 59%), and normal weight (12%; 9%). The endpoint data show that between 13 and 15 years of age, maternal concern regarding their adolescent's weight decreased in all weight-status groups. Predictors of maternal misclassification of adolescent overweight were adolescent BMI z score, recent weight-management practices, weight history, sex, and maternal concern regarding her adolescent's weight. These results reinforce the need for strategies in primary care that are implemented throughout adolescence to improve maternal awareness of childhood overweight.
