Body Mass Index Changes during Pregnancy and Perinatal Outcomes - A Cross-Sectional Study

Abstract

Objective To evaluate the relation between changes the body mass index (BMI) percentile, reflected in the Atalah curve, and perinatal outcomes. Methods A cross-sectional study with 1,279 women was performed. Data regarding gestational weight, sociodemographic characteristics and perinatal outcomes were collected through medical charts, prenatal card and interviews in the postpartum period. Women could be classified according to the Atalah curve in the following categories: low weight, adequate weight, overweight, and obese. The BMI was calculated at the first and at the last prenatal care visits, and these values were compared. Results An increase in the BMI category according to the Atalah classification occurred in 19.9% of pregnant women, and an increase of 3.4, 5.8 and 6.4 points of BMI were found for women respectively classified in the adequate weight, overweight and obese categories at the first prenatal visit. Women with high school education presented a lower chance of increasing their BMI (odds ratio [OR] 0:47 [0.24-0.95]). Women who evolved with an increase in the the Atalah classification were associated with cesarean section (OR 1.97-2.28), fetal macrosomia ) and large for gestational age newborn (OR 2.88-9.83). Conclusion Pregnant women who gained enough weight to move up in their BMI classification according to the Atalah curve had a higher chance of cesarean section and macrosomia. Women classified as obese, according to the Atalah curve, at the first prenatal visit had a high chance of cesarean section and delivering a large for gestational age newborn.

Incidence and risk factors for Preeclampsia in a cohort of healthy nulliparous pregnant women: a nested case-control study

“…The high prevalence of obesity in our population may explain the incidence of preeclampsia. Despite the lack of data available on this topic in our country, a recent cross-sectional study involving 1,279 pregnant women showed that the prevalence of overweight or obesity during the first prenatal visit was almost 40% 22 .…”

Uterine vascular resistance and other maternal factors associated with the risk of developing hypertension during pregnancy

“…MAP was found to be an important risk factor, as also was uterine artery PI, regardless of the presence or absence of a diastolic notch. Morais et al (14) determined the low weight, normal weight, overweight, and obesity curve according to gestational age (14) and observed that an appropriate BMI for a gestational age of 25 weeks would be 22.5 to 27 kg/m 2 . The mean BMI detected in the present study was 27.2 kg/m 2 , demonstrating a tendency towards obesity in the population under study.…”

“…Ou seja, estimase que a cada dez gestantes, acompanhadas na assistência pré-natal, seis apresentem algum tipo de desvio antropométrico. Os achados de outras investigações sobre a temática, realizadas no Brasil, corroboram o presente estudo (ANDRETO et al, 2006;FONSECA et al, 2014;MARANO et al, 2012;MELLER;SANTOS, 2009;MORAIS et al, 2018;NIQUINI et al, 2013;RODRIGUES et al, 2020).…”
