Abstract Background Pre-pregnancy body mass index and gestational weight gain were related to perinatal outcomes. It was not know the changes of pre-pregnancy body mass index, weight gain during pregnancy and its effect on perinatal outcomes in two-child women.Methods This was a retrospective study. Data of single term women delivered in the First Affiliated Hospital of Sun Yat-sen University were collected from July 2017 to June 2018. Gestational weight gain criteria of the American Institute of Medical Research and pre-pregnancy body mass index classes were used to evaluate the effects on pregnancy outcomes.Results A total of 3049 cases were enrolled in the study. Overweight cases was 9.0% and obesity was 2.4%. The weight gain of the two-child women was less than that of primipara(12.4±3.9vs13.3±4.0kg, P<0.001). The proportion of primipara with excessive weight gain was higher compared to two-child women(20.1%versus17.3%, P<0.001). There were 40.0% overweight primipara and 55.2% of two-child women had excessive weight gain. And 40.5% primipara and 54.5% two-child women of obesity had excessive weight gain during pregnancy. Obese primipara increased the risk of pre-eclampsia (aOR2.38, 95%CI 0.76-7.46). And the odds of diabetes mellitus and large for gestational age also increased in this group (aOR3.49, 95%CI 1.46-8.35 and aOR7.65, 95%CI 1.83-31.97, respectively). Two-child women had similar results. Underweight primipara with excessive weight gain increased the pre-eclampsia risk (aOR2.26, 95%CI 0.29-17.46). Normal weight and overweight/obese primipara also had similar results. But in two-child women, only overweight/obesity increased the risk of pre-eclampsia (aOR2.01, 95%CI 0.41-9.98). Underweight two-child women with less weight gain increased the risk of diabetes(aOR2.06, 95%CI 0.43-9.8). Two-child women with overweight/obese increased the odds of LGA even if they had less weight gain(aOR2.58, 95%CI 0.11-63.22). Normal weight primipara and two-child women with overweight and obese with excessive weight gain had similar results. On the other way, underweight primipara with less weight gain increased the risk of SGA(aOR1.74, 95%CI 0.81-3.76).Conclusions Gestational weight gain of two-child women was less than primipara. Overweight/obese women with excessive weight gain of two-child women increased the risk of adverse outcomes.

Aim: To evaluate the effects of gestational weight gain on perinatal outcomes in woman with excessive pre-gravid body mass index. Material and Methods: The study group consisted of 197 overweight or obese women who delivered full-term newborns at the 1st Department of Obstetrics and Gynecology, Medical University of Warsaw. Group A included 89 (45.2%) women with inadequate or adequate weight gain. Group B included 108 patients (54.8%) with excessive weight gain during pregnancy. Results: No significant differences in the occurrence of gestational diabetes, hypertension or intrahepatic cholestasis between the analyzed groups were observed. Excessive weight gain was positively correlated with the incidence of cesarean delivery (67.6% vs 32.4%, p=0.009), newborns’ birthweight (3627g±519 vs 3406g±521, p=0.009) and the risk of low for gestational age infants (26.9% vs 12.4%, p=0.01). The highest risk of low for gestational age new born was related to gestational weight gain of about 15 kg. Appropriate preconception counselling for overweight and obese women may reduce the risk of low for gestational age infants.

Abstract The aim of this study is to investigate the association between maternal gestational weight gain (GWG) and preterm birth according to pre-pregnancy body mass index (BMI) and maternal age. We did a cohort, hospital-based study in Quzhou, South China, from 1 Jan 2018 to 30 June 2019. We selected 4274 singleton live births in our analysis, 315 (7.4%) of which were preterm births. In the overall population, excess GWG was significantly associated with a decreased risk of preterm birth compared with adequate GWG (adjusted OR 0.81 [95% CI 0.72–0.91]), and the risk varied by increasing maternal age and pre-pregnancy BMI. Interestingly, underweight women who older than 35 years with excess GWG had significantly increased odds of preterm birth compared with adequate GWG in underweight women aged 20–29 years (2.26 [1.06–4.85]) and normal weight women older than 35 years (2.23 [1.13–4.39]). Additionally, low GWG was positively and significantly associated with preterm birth overall (1.92 [1.47–2.50]). Among normal weight women category, compared with adequate GWG women aged 20–29 years did, those older than 20 years with low GWG, had significantly higher odds of preterm birth, which increased with maternal age (1.80 [1.16–2.79] in 20–29 years, 2.19 [1.23–3.91] in 30–34 years, 3.30 [1.68–6.46] in ≫ 35 years). In conclusion, maternal GWG was significantly associated with the risk of preterm birth, but the risk varied by pre-pregnancy BMI and maternal age.

Abstract Background Identifying the risk factors for preeclampsia (PE) is essential for the implementation of preventive actions. In the present study, we aimed at exploring the association between total gestational weight gain (GWG) and PE. Methods We performed a population-based cohort survey of 98,820 women with singleton pregnancies who delivered in Slovenia from 2013 to 2017. Aggregated data were obtained from the National Perinatal Information System (NPIS). The main outcome measure was the incidence of PE. The main exposure variable was total GWG standardized for the gestational duration by calculating the z-scores. The associations between total GWG and PE stratified by pre-pregnancy body mass index (BMI) categories adjusted for a variety of covariates were determined using multivariable logistic regression. We calculated the crude odds ratio (OR) and adjusted odds ratio (aOR) with a 95% confidence interval using a two-way test. Results Excessive GWG was associated with increased odds of PE in all pre-pregnancy BMI categories. The increase in the odds of PE by 445% was the highest in underweight women and by 122% was the lowest in obese women. Low GWG was associated with decreased odds of PE in all pre-pregnancy BMI categories except in normal-weight women with a GWG below −2 standard deviation (SD) and underweight women. The decrease in the odds of PE by 67% was the highest in obese women and by 41% was the lowest in normal-weight women. Conclusion Excessive GWG is a significant risk factor for PE, especially in underweight women, while low GWG is an important protective factor against PE, especially in obese women.

Objectives: The study was undertaken to explore the effects of prepregnancy body mass index (BMI) and excess weight gain on maternal and neonatal outcomes different maternal and neonatal outcomes. Methods: Obstetrics records of 496 singleton pregnant women delivered between 2007 and 2009 in IBN SINA Medical College Hospital were reviewed. On the basis of BMI on their first visit the patients were divided into 3 groups; Mat BMI Gr 1, normal (BMI 20–24.9 Kg/m<sup>2</sup>, n=366), Mat BMI Gr 2, overweight (BMI 25-29.9 Kg/m<sup>2</sup>, n=102), Mat BMI Gr 3, obese (BMI >30 Kg/m<sup>2</sup>, n=28). On the basis of gestational weight gain, the subject divided into 2 categories, Gets WtGain Gr A, gestational weight gain 8–15.9 Kg (n=315), Gest WtGain Gr B, gestational weight gain >16 Kg weight gain (n=181). Data were expressed as number (percentage). Proportion test was performed for comparison between two groups. P value <0.05 was taken as level of significance. Results: of the total 496 pregnant women 74.59% were between 19-34 years of age. Among all the women 64.11% had high school education of different grade. Of all the pregnancies 23.18% were nulliparous. Of the total 496 women 366 (79.79%) were normal weight, 102 (20.56%) overweight and 28 (5.64%) obese. Obese women group had significantly higher proportion of hypertensive cases compared to the normal weight (p<0.001) and overweight (p<0.01) group. Relatively higher proportion of macrosomia, birth trauma, shoulder dystocia and NICU admission among babies of obese women (p=ns). One hundred and eighty one (36.49%) of study subjects had gestational weight gain above the cut-off (>16 kg) value (p<0.001). Women with weight gain bout the cut-off level had relatively higher proportion of macrosomic babies (p=ns). Conclusions: The data reconfirmed that obesity is associated with hypertension. Significant proportion of women had weight gain more than cut-off value which needs to be addressed to ensure sound maternal and fetal wellbeing. However, a multicentre large scale study is warranted which may help the researchers to conclusively comment on the issue and thus plan future strategies for health care during pregnancy. Key words: Pre-pregnancy body mass index, gestational weight gain, obstetrics outcomes. DOI: http://dx.doi.org/10.3329/bjms.v10i3.8364 BJMS 2011; 10(3): 195-199

Abstract The gestational weight gain (GWG) range of Chinese women with gestational diabetes mellitus (GDM) still remains unclear. Our objective was to identify the ranges of GWG in Chinese women with GDM, and to investigate the associations between pre-pregnancy body mass index (BMI), GWG and maternal-infant adverse outcomes. GDM Women delivering singleton from 2013 to 2018 in a tertiary public hospital were collected. Logistic regression analysis was used to assess the joint effects of pre-pregnancy BMI and GWG on maternal-infant adverse outcomes. Finally, 14,578 women were collected. The ranges of GWG of Chinese women with GDM in the underweight, normal weight, overweight and obese groups were 5.95-21.95kg, 4.23-21.83kg, 0.88-21.12kg and-1.76-19.95kg, respectively. The risks of large for gestational age (LGA), macrosomia and cesarean delivery were significantly increased with the increase of pre-pregnancy BMI. Furthermore, the risks of LGA, macrosomia and cesarean delivery were significantly higher in normal weight group with GWG higher than the National Academy of Medicine’s (NAM) recommendation. Similarly, in overweight group with GWG higher than NAM recommendation, the risks of LGA were significantly higher, while, the risks of macrosomia were significantly lower. In conclusion, the ranges of GWG in GDM women were different with NAM recommendation.
