Association between gestational weight gain and birth weight: NISAMI Cohort

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.

Association Between Maternal Dietary Pattern and Infant Birth Weight: a Structural Equation Modelling Analysis

“…In the follow-up of the study, the pregnant women were monitored until the birth of their child [19,20] . The birth weight was measured with the child naked using a digital paediatric scale (Welmy®), with a capacity of 15 kg and a 10 g interval.…”

“…Information on birth weight was collected from the municipality's Epidemiological Survey (VIEP) registration system. When necessary, home visits were performed at the end of the study for those pregnant women whose data on gestational outcomes were not found in the VIEP [19,20] ..…”

“…The details of the cohort procedures are described in previous studies [19,20] . In the rst stage of the cohort (baseline), the information on socio-economic and demographic conditions, reproductive and/or obstetric history, and lifestyle were collected during the enrolment of pregnant women at the prenatal services, and responses were recorded using a questionnaire.…”

Pre-gestational anthropometric status and birth weight: NISAMI cohort

“…As medidas antropométricas são recomendadas para o acompanhamento nutricional de gestantes, devido à sua importância na prevenção da morbimortalidade perinatal, prognóstico do desenvolvimento fetal e promoção de saúde da mulher 1 O estado nutricional pré-gestacional pode influenciar tanto o ganho de peso durante a gestação como a perda de peso no pós parto 4 . O ganho de peso gestacional insuficiente está relacionado com a ocorrência de recémnascidos de baixo peso [4][5][6] e peso inadequado ao nascer.…”

Paralelo a isso, o ganho de peso excessivo no período gestacional também se DOI: 10.15343/0104-7809.202145233241 associa ao baixo peso ao nascer (BPN), onde essa associação pode estar relacionada com o aumento de complicações gestacionais, as quais impactam no peso da criança e são consideradas como um dos principais fatores de risco para desfechos gestacionais desfavoráveis 7 .…”
