Abstract
Objectives:
to identify the prevalence and to analyze the factors associated with low birth weight in a subnormal urban cluster in Pernambuco under Family Health Strategy’s care.
Methods:
a cross-sectional study with a census sample carried out between July and October in 2015. The variables studied were age and years of maternal schooling, social status, housing, water supply, waste disposal, prenatal care, alcohol consumption and cigarette smoking during pregnancy, along with gender, birth weight and prematurity. Stata 12.1 was utilized in order to understand the factors associated with low birth weight through uni-and-multivariate Poisson analysis, adjusted and gross prevalence ratios, composing a final statistical model considering p value <0.05 for statistical significance.
Results:
regarding the 294 children the LBW prevalence was 12.2% (CI95% = 8.7-16.5). Children whose mothers reported drinking during pregnancy were 2.78 times more at risk of being born with low birth weight (p<0.001) when compared with children whose mothers did not report this practice in gestation.
Conclusions:
the study evidenced the relevance maternal habits bears in the newborns’ health.
