Abstract:
Objective:To determine the gestational weight gain and its risk factors and adverse effects among pregnant women in Beijing.Methods:Between June 2018 and June 2019, all registered infants and their mothers in a child care center of a third-tier-class hospital in Beijing were selected. A self-made questionnaire was used to collect the basic information of the maternal mothers. Chi-square test and analysis of variance were used to describe the basic characteristics of the study subjects and clarify the harmful effect of gestational weight gain for maternal and infant health. Multiple logistic regression analysis was used to analyze the risk factors of both insufficient and excessive weight gain during pregnancy.Results:A total of 3732 maternal mothers and their babies were included. The average weight gain of maternal mothers during pregnancy was 13.0 kg. The results of this study showed that the proportion of insufficient weight gain during pregnancy was 31.8% and the proportion of excessive weight gain was 24.1%. It was further found that young age, pre-pregnancy body mass index indicating overweight and obesity, primipara, and low education were independent risk factors for excessive weight gain during pregnancy. The risk of excessive weight gain of pre-pregnancy overweight and obesity was 2.40 times ( OR=2.40, 95% CI=1.91-3.03, P<0.001) and 2.90 times higher, respectively, ( OR=2.90, 95% CI=1.59-5.27, P<0.001) when compared with that of pre-pregnancy normal weight. In addition, our results suggested that excessive weight gain significantly increased the risk of macrosomia for the infant and the risk of cesarean section, gestational hypertension, and postpartum weight retention for maternal mothers. Conclusions:Age, pre-pregnancy BMI, primipara, and education level were the influencing factors for gestational weight gain. Considering the serious harmful effects of both insufficient and excessive weight gain for maternal and infant health, weight management during pregnancy should be strengthened for these high-risk populations in the future.
