Abstract
Abstract Objectives: this study aims to evaluate the association between gestational weight gain and the weight of newborns from one municipality in Recôncavo Baiano region. Methods: this is a prospective cohort (NISAMI Cohort), conducted with 185 pregnant women living in the urban area of the municipality of Santo Antônio de Jesus, using the prenatal service of the Family Health Units, between April 2012 and June 2013. The pregestationalBMI and the third trimester of pregnancy were used to assess maternal anthropometric status.Birth weight data were collected from the Epidemiological Surveillance of the municipality. Stata 12.0 software was used for statistical analysis. Logistic regression analysis was used to evaluate to assess the association. Results: among the 185 women evaluated, 33.5% presented inadequate weight gain during pregnancy. The prevalence of inadequate birth weight was 20% (birth weight ≤ 2.999g and ≥ 4.000 g). It was observed that inadequate weight gain during pregnancy is considered an embarrassing factor for birth weight (OR= 2.6; CI95%= 1.5-3.5); adjusted for the following variables: alcohol consumption, duration of pregnancy, and gestational complications. Conclusion: the research results suggest that weight gain throughout pregnancy influences the weight of the conceptus, indicating the need for nutritional interventions in all trimesters of pregnancy, promoting a healthy weight gain throughout the gestational cycle.
Highlights
Birth weight is considered a relevant event in the health issue because it is related to health and nutrition conditions of children in their first months of life
Regarding the prevalence of low birth weight (LBW), this is lower in regions where access and quality of health is adequate, and nutrition conditions and socioeconomic status is favorable.[5]
The prevalence of inadequate birth weight was 20%
Summary
Birth weight is considered a relevant event in the health issue because it is related to health and nutrition conditions of children in their first months of life. It is a determining factor for the development of neonatal morbidity and mortality. Regarding epidemiological data on outcomes studied in 2001, a prevalence of 5.9% of macrosomia was recorded in Brazil, with the Northeast (7.5%) and North (7.3%) regions, the ones with higher prevalence when compared to the national data. There was a decrease in national rates (5.5%) in the Northeast (6.9%) and North (6.5%) regions.[4]. In the North and Northeast and more impoverished regions of Brazil, the recorded prevalence was 9.7% in 19946 and it decreased, mainly in the Northeast Region, to 6.8% in 2000.7
