Abstract
The study was to assess the associations of prepregnancy body mass index (BMI) and gestational weight gain (GWG) with pregnancy outcomes. This was a retrospective analysis of 2973 nulliparous women who delivered single live babies. Prepregnancy BMI was categorized as underweight (<18.5 kg/m2), normal weight (18.5–24.9 kg/m2) or overweight/obese (≥25.0 kg/m2). GWG was categorized as inadequate, adequate or excessive. 567 (19.1%) women were overweight/obese, and 1600 (53.8%) exhibited excessive GWG. Compared with women of normal weight, overweight/obese women had a higher incidence of cesarean section (odds ratio, 95% confidence interval: 2.02, 1.59–2.56), postpartum hemorrhage (1.50, 1.05–2.14), preterm delivery (2.51, 1.83–3.45), preterm premature rupture of membranes (2.11, 1.32–3.38), gestational diabetes mellitus (2.04, 1.65–2.53), gestational hypertension (7.68, 4.21–14.00), preeclampsia (1.98, 1.18–3.33) and small for gestational age (2.81, 1.21–6.54). Compared with adequate GWG, excessive GWG increased the incidence of cesarean section (2.02, 1.59–2.56), preterm delivery (1.48, 1.05–2.71), preeclampsia (1.78, 1.34–4.27) and macrosomia (2.61, 1.61–4.25), and reduced the incidence of gestational diabetes mellitus (0.75, 0.62–0.92). High prepregnancy BMI and excessive GWG in nulliparous Chinese women are associated with adverse pregnancy outcomes. Weight control before and during pregnancy could reduce the complications of pregnancy.
Highlights
Several previous studies have examined the influence of high prepregnancy body mass index (BMI) and excessive gestational weight gain (GWG) on perinatal outcomes, relatively few have been conducted in China, and there are only limited data concerning women giving birth in Beijing
In comparison to women of normal weight, overweight/obese women had a higher incidence of cesarean section, postpartum hemorrhage (PPH), preterm delivery, premature rupture of the membranes (PPROM), GDM, GHT, preeclampsia and small for gestational age (SGA) (Table 3), with the association strong for GHT (OR, 7.68; 95%confidence intervals (CIs), 4.21–14.00)
The main findings of the present study are that, compared to women of normal weight, overweight/ obese women had a higher incidence of cesarean section, PPH, preterm delivery, PPROM, GDM, GHT, Inadequate GWG (N = 307)
