          Abstract

          O objetivo do estudo foi identificar os fatores associados ao excesso de peso em crianças brasileiras menores de cinco anos. Foram utilizados dados da Pesquisa Nacional de Demografia e Saúde (PNDS) de 2006, um estudo transversal de base domiciliar. O diagnóstico do excesso de peso baseou-se no índice peso-para-altura superior a 2 escores z acima da mediana do padrão antropométrico da Organização Mundial de Saúde - 2006. A população estudada constituiu-se de 4.388 crianças. A prevalência de excesso de peso nas crianças foi descrita segundo variáveis socioeconômicas, demográficas, antropométricas e comportamentais. Foram realizadas análises bruta e ajustada através da Regressão de Poisson e todas foram estratificadas pelo sexo da criança. A prevalência de excesso de peso foi de 6,6%. Após análise ajustada, o índice de massa corporal materno e o peso ao nascer foram associados ao excesso de peso. Além disso, o excesso de peso mostrou-se associado ao tempo de amamentação exclusiva, nos meninos e ao nível socioeconômico e situação conjugal, nas meninas. Enfatiza-se a necessidade da implementação de políticas públicas que atuem, o mais precocemente possível, nos principais determinantes do excesso de peso.

          The scope of the study was to identify factors associated with excess weight in Brazilian children less than five years of age. Data from a cross-sectional home-based study entitled the National Demographic and Health Survey (NDHS) of 2006 were used. The diagnosis of excess weight was performed using the weight-for-height greater than 2 z scores above the median anthropometric standard recommended by the World Health Organization in 2006. The population under study consisted of 4,388 children. The prevalence of excess weight in children was described according to socio-economic, demographic, anthropometric, and behavioral variables. Crude and adjusted analyses were carried out to assess statistical significance stratified by gender using Poisson regression. The prevalence of excess weight was 6.6%. After adjusting for potential confounding factors, maternal body mass index and birth weight were associated with excess weight. Furthermore, being overweight was associated with exclusive breastfeeding for boys and with the socio-economic level and marital status of the mother for girls. The need to implement public policies that act on the major determinants of excess weight since childhood is emphasized.

            The role of conceptual frameworks in epidemiological analysis: a hierarchical approach.

            This paper discusses appropriate strategies for multivariate data analysis in epidemiological studies. In studies where determinants of disease are sought, it is suggested that the complex hierarchical inter-relationships between these determinants are best managed through the use of conceptual frameworks. Failure to take these aspects into consideration is common in the epidemiological literature and leads to underestimation of the effects of distal determinants. An example of this analytical approach, which is not based purely on statistical associations, is given for assessing determinants of mortality due to diarrhoea in children. Conceptual frameworks provide guidance for the use of multivariate techniques and aid the interpretation of their results in the light of social and biological knowledge.
