<b>Females and post-pubescent adolescents: groups with high exposure to the development of body image dissatisfaction in São Bonifácio, Santa Catarina State, Brazil

Abstract

To determine the prevalence of body image dissatisfaction in adolescents and analyse associated factors. The sample under analysis comprised 278 adolescents, 10- to 17-year-old students from government schools in a small town in southern Brazil. Sociodemographic information was collected (age, sex, area of residence and educational level of family head), coupled to self-assessment of sexual maturation and body image perception (scale of body silhouettes). Frequency distribution was employed for statistical analysis; Student’s t test was applied for independent samples; chi-square and Fisher's exact test and Poisson regression with robust variance adjustment were used. The prevalence of body image dissatisfaction was 59.3%, or rather, higher among females (65.6%) than among males (53%). An association between body image and sexual maturation existed which revealed that post-pubescent adolescents were more likely to show body image dissatisfaction when compared to their pre-pubescent peers. Females and post-pubescent adolescents were more likely to feel body image dissatisfaction. Intervention programs may be proposed as strategies for the construction of a positive body image.
