Abstract
Objective: To compare the characteristics of a set of weight-related and well-being variables among adolescents according to gender and age. It was hypothesised that time of puberty, not age in itself, might be the turning point for gender dissimilarities.
Methods: Data were drawn from the Portuguese 2006 HBSC/WHO database and were disaggregated by gender and age group. Groups were compared for dieting, body image, health perception and happiness variables on the bivariate level using cross-tabulations. Separate analysis of the dependent variables was further conducted for 11-year-olds comparing males with pre- and post-menarche females.
Results: Dieting and a negative body image were consistently more prevalent among girls and increased with age. At 11 years significantly more post-menarche girls were dieting and dissatisfied with their body image than boys and their pre-menarche counterparts. A poor self-rated health and the perception of unhappiness tended to be more common among older adolescents and among girls.
Conclusions: Pubertal timing, and not age in itself, appears as the turning point for gender dissimilarities. Both gender- and age-specific differences as well as pubertal timing have to be taken into account by any physician when assessing an adolescent in order to be able to adapt the intervention.
