Resumo:
O objetivo do artigo foi verificar a associação entre consumo alimentar, atividade física, fatores socioeconômicos e percentual de gordura corporal em escolares de 7 a 14 anos de idade. Estudo transversal realizado com amostra probabilística de 2481 escolares matriculados em escolas públicas e privadas de Florianópolis, Santa Catarina, Brasil. O percentual de gordura corporal foi investigado por meio das dobras cutâneas do tríceps e subescapular. Foram realizadas análises brutas e ajustadas por meio da regressão de Poisson, estimando-se razões de prevalência e intervalos de confiança de 95%. A prevalência do excesso de gordura corporal foi de 23,9%, não apresentando diferença significativa entre sexo (p = 0,359) e idade (p = 0,202). A gordura corporal associou-se a diferentes fatores nos escolares de 11 a 14 anos: consumir menos que 3 refeições ao dia (RP = 1,62; IC: 1,38-1,91) e consumir alimento de risco mais que 3 vezes ao dia (RP = 0,61; IC: 0,47-0,79). Não foi observada diferença significativa com atividade física. A elevada prevalência de excesso de gordura corporal verificada evidencia a necessidade de estímulo à adoção de práticas comportamentais mais saudáveis (em relação à alimentação e à atividade física) pelos escolares.

Abstract:
The article aims to identify food consumption, physical activity and socioeconomic factors associated with body fat percentage in schoolchildren 7-14 years old. This is a crosssectional study with a probability sample of 2481 students from public and private schools of Florianópolis, Santa Catarina state, Brazil. Body fat percentage was investigated by using skinfold triceps and subscapular. Poisson regression was performed to test associations between excess body fat and independent variables, estimating prevalence ratios and confidence intervals of 95%. The prevalence of body fat excess was 23.9%, but no significant difference between sex (p = 0.359) and age (p = 0.202). The body fat excess was associated with different factors in schoolchildren of 11-14 years: food consumption less than three meals a day (OR = 1.62, CI: 1.38 to 1.91) and risk food consumption more than 3 times a day (OR = 0.61 CI: 0.47 to 0.79). There was no significant difference with physical activity. The high prevalence of excess body fat verified denotes the need for encouraging the adoption of healthier behavioral practices (in relation to nutrition and physical activity) by schoolchildren.
