Description
Summary:Abstract Objectives: to analyze the association between exclusive breastfeeding duration (EBF) and the age at which complementary feeding was introduced (CF) with the excess of body fat (BF) in schoolchildren from Florianópolis/SC, southern of Brazil. Methods: cross sectional study, with probability sample of 1,531 schoolchildren aged 7-10 years from Florianópolis/SC. The percentage of BF was defined based on triceps and subscapular skinfolds. Information about EBF, CF and confounders variables were obtained through a questionnaire sent to parents or guardians. Multivariate analyzes were performed using Poisson. Results: the prevalence of BF excess was 37.9% (CI95%: 32.4; 43.6), and 30.6% of children received EBF for 4-6 months (CI95%: 17, 3; 48, 2). The duration of EBF less than 4 or more than 6 months was associated with higher prevalence of BF excess, even after adjustment (p=0.015). Introduction of food groups had no association with BF excess. Conclusions: the association between EBF and the excess of body fat for less than 4 months and higher prevalence of BF excess is probably a consequence of early introduction of others milk types, whilst association between EBF for more than 6 months and higher prevalence of BF excess is because of a catch-up growth situation. Resumo Objetivos: analisar a associação da duração do aleitamento materno exclusivo (AME) e idade de introdução da alimentação complementar (AC) com o excesso de gordura corporal (EGC) em escolares de Florianópolis/SC. Métodos: estudo transversal com amostra probabilística de 1.531 escolares de 7-10 anos de escolas públicas/privadas de Florianópolis/SC. O EGC foi avaliado pela aferição de dobras cutânaeas tricipital e subescapular. Dados sobre AME, AC e variáveis de confusão foram obtidos por entrevista. Regressão de Poisson foi empregada nas análises ajustadas. Resultados: a prevalência de excesso de EGC e AME foi 37,9% (IC95%: 32,4-43,6) e 30,6% (IC95%: 17,3-48,2), respectivamente. O AME por um período menor que 4 meses e maior que 6 meses se manteve associado ao EGC após ajuste pelas variáveis confundidoras. A introdução dos grupos de alimentos na AC não esteve associação ao EGC. Conclusões: a associação do EGC com a AME por menos de quatro meses deve-se possivelmente à oferta precoce de outros tipos de leite como complemento ao materno, enquanto que a associação com AME por mais de seis meses pode ser devido ao fenômeno de aceleração do crescimento.
