ABSTRACT:Objective: To determine the prevalence of excessive gestational weekly weight gain and to identify its association with demographic, socioeconomic, obstetric, anthropometric, and behavioral characteristics. Methods: This cross-sectional study included 328 pregnant women attending all health units in the urban area of Vitória da Conquista, Bahia. The data were collected from May 2010 to June 2011. The weekly weight gain was evaluated according to the current recommendations of the Institute of Medicine. The association among the studied factors and the excessive weekly weight gain was observed in pregnant women in the second and third trimesters, using the Poisson regression with robust variance. Results: The prevalence rate of excessive weekly weight gain in pregnant women in the second and third trimesters was found to be 42.5%. The determinants of excessive weekly weight gain were family income < 1 minimum wage (PR: 2.65; 95%CI 1.18 -4.83) and pregestational weight status overweight/obesity (PR: 1.33; 95%CI 1.01 -1.75). Conclusion:The results emphasize the importance of monitoring the weight gain during pregnancy. The evaluation of the weekly weight gain enables early interventions with the goal of preventing the excessive total weight gain and its consequences for both the mother and the child.
Resumo Objetivo Avaliar a prevalência e os fatores associados ao déficit estatural em crianças de 6 a 24 meses. Metodologia Trata-se de um estudo transversal realizado com 360 crianças atendidas em todas as unidades de saúde da zona urbana do município de Vitória da Conquista, BA. Foi aplicado um questionário para coleta de informações e foram aferidas medidas antropométricas de peso e estatura. O estado nutricional foi avaliado de acordo com os pontos de corte para os índices antropométricos preconizados pela Organização Mundial de Saúde. A associação entre os fatores em estudo e o déficit estatural foi verificada através da análise de regressão de Poisson, com variâncias robustas. Resultados A prevalência de déficit estatural nas crianças avaliadas foi de 13,6%. Os fatores que se associaram ao desfecho foram: ausência de trabalho paterno (RP: 2,46; IC 95%: 1,34-4,49) e baixo peso ao nascer (RP: 2,29; IC 95%: 1,27-4,13). Conclusão Os resultados mostram uma prevalência considerável do déficit de estatura entre as crianças menores de 2 anos, destacando a importância do monitoramento nutricional e a influência de fatores obstétricos e socioeconômicos.
