Body image and obesity in children from public primary schools in Acapulco, Mexico: A cross-sectional study.

Abstract

Childhood obesity is a global problem, causing social and psychological damage, as well as physical health risks. This study estimated the occurrence of body image dissatisfaction in primary schoolchildren aged 9-13 years and investigated its association with obesity and other factors. A cross-sectional study was conducted, for which 533 students attending three public primary schools in Acapulco were recruited. Students completed a facilitated self-administered questionnaire about their age, sex, socioeconomic level, body image satisfaction, and perception of their parents' body image. We registered anthropometry of the students and calculated body mass index (BMI). We examined the associations of BMI category and other factors with body image dissatisfaction, calculating the cluster-adjusted odds ratio and 95% confidence intervals. From the total number of participants, 75% (181/243) of girls and 73% (170/232) of boys were dissatisfied with their body image and wanted a slimmer body. About half were overweight or obese: 45% (121/271) of girls and 52% (135/262) of boys. Overweight or obese children were much more likely to be dissatisfied with their body image (cluster adjusted: 6.73; 95% CI: 5.42-8.36). No other factors were significantly associated with body image dissatisfaction. One-third of the girls (32%, 86/271) and 17% (45/261) of the boys reported an underweight desired body image. The high level of obesity is a cause for concern and an even higher level of body image dissatisfaction as well. The high dissatisfaction among children suggests that boys, as well as girls in Mexico, may now be subjected to intense social pressure about desirable body image.
