The aim of this study was to determine the prevalence of overweight, pre-pregnancy and gestational obesity and verify the association with the birth weight of the newborn. A descriptive cross-sectional study was conducted with 712 pregnant women admitted for delivery at the School of Medicine of Jundiaí hospital. The variables studied were socio-demographics, pregnancy, pre-pregnancy weight, prenatal care, total gestational weight gain and birth weight of the newborn. The majority (99.7%) had a pre-natal and 84.6% > 6 visits. The prevalence of pre-pregnancy overweight was 34.7%, and excessive total weight gain was 36.9%. A significant association was observed between the pregnant women's BMI classification and the newborn's weight (NB) classification and between total weight gain classification of the mother and the newborn's weight classification. In pregnant women with excessive weight a higher prevalence of newborns with appropriate weight was observed. In contrast, women with insufficient weight gain had 2.15 times higher risk of underweight newborns and 2.85 times higher risk of low weight newborns. Although a significant percentage of overweight pregnant women was observed, this influenced the insufficient weight of the pregnant woman though not the birth weight of the newborns.
本研究的目的是确定超重、孕前肥胖和孕期肥胖的患病率，并验证其与新生儿出生体重的关联。对在容迪亚伊医院医学院住院分娩的712名孕妇进行了一项描述性横断面研究。所研究的变量包括社会人口统计学、妊娠情况、孕前体重、产前护理、孕期总体重增加以及新生儿出生体重。大多数孕妇（99.7%）接受了产前检查，84.6%的孕妇产前检查次数超过6次。孕前超重的患病率为34.7%，孕期总体重增加过多的患病率为36.9%。观察到孕妇的BMI分类与新生儿体重（NB）分类之间以及母亲的总体重增加分类与新生儿体重分类之间存在显著关联。在体重增加过多的孕妇中，观察到出生体重正常的新生儿患病率较高。相比之下，体重增加不足的孕妇生出低体重新生儿的风险高2. (15倍，生出极低体重新生儿的风险高2.85倍。尽管观察到相当比例的超重孕妇，但这影响的是孕妇体重不足，而非新生儿的出生体重。
