“…An association between GWG and birth weight has been reported by several studies [17,[77][78][79], and women who gain inadequate gestational weight are at an increased risk of having a baby with LBW or a pre-term birth [21,[80][81][82]. In the studies in this review, the majority of LBW babies were born to women who gained inadequate gestational weight.…”

Gestational weight gain and its effect on birth outcomes in sub-Saharan Africa: Systematic review and meta-analysis

Introduction An increased metabolic demand during pregnancy is fulfilled by gaining sufficient gestational weight. Women who gain inadequate-weight are at a high-risk of premature birth or having a baby with low-birth weight. However, women who gain excessive-weight are at a high-risk of having a baby with macrosomia. The aim of this review was to determine the distribution of gestational weight gain and its association with birth-outcomes in Sub-Saharan Africa. Methods For this systematic review and meta-analysis, we performed a literature search using PubMed, Medline, Embase, Scopus, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. We searched grey-literature from Google and Google Scholar, and region-specific journals from the African Journals Online (AJOL) database. We critically appraised the included studies using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Two independent reviewers evaluated the quality of the studies and extracted the data. We calculated pooled relative-risks (RR) with 95% confidence intervals. Results Of 1450 retrieved studies, 26 met the inclusion criteria. Sixteen studies classified gestational weight gain according to the United States Institute of Medicine recommendations. The percentage adequate amount of gestational weight ranged from 3% to 62%. The percentage of inadequate weight was >50% among nine studies. Among underweight women, the percentage of women who gained inadequate gestational weight ranged from 67% to 98%. Only two studies were included in the meta-analyses to evaluate the association of

“…Maternal overweight, obesity, and morbid obesity are already known to be associated with adverse obstetric and neonatal outcomes [3,10]. In particular, maternal obesity is associated with gestational diabetes mellitus (GDM) [11,12], preeclampsia [12], congenital malformations and macrosomia [3], preterm birth [3], low Apgar scores [4], admittance to neonatal intensive care unit [13], low-weight newborns [3,14], and with an increase in obstetric interventions such as pregnancy caesarean section [12,15] and labor induction [16,17]. In the long term, maternal obesity is associated with an increased risk of diabetes mellitus and cardiovascular diseases in women, and with an increased risk of childhood obesity in the newborn [2,4].…”

Over the past few decades, overweight and obesity have become a growing health problem of particular concern for women of reproductive age as obesity in pregnancy has been associated with increased risk of obstetric and neonatal complications. The objective of this study is to describe the incidence of obstetric and perinatal complications in relation to maternal body mass index (BMI) at the time prior to delivery within the Spanish Health System. For this purpose, a cross-sectional observational study was conducted aimed at women who have been mothers between 2013 and 2018 in Spain. Data were collected through an online survey of 42 items that was distributed through lactation associations and postpartum support groups. A total of 5871 women answered the survey, with a mean age of 33.9 years (SD = 4.26 years). In the data analysis, crude odds ratios (OR) and adjusted odds ratios (AOR) were calculated through a multivariate analysis. A linear relationship was observed between the highest BMI figures and the highest risk of cephalopelvic disproportion (AOR of 1.79 for obesity type III (95% CI: 1.06–3.02)), preeclampsia (AOR of 6.86 for obesity type III (3.01–15.40)), labor induction (AOR of 1.78 for obesity type III (95% CI: 1.16–2.74)), emergency C-section (AOR of 2.92 for obesity type III (95% CI: 1.68–5.08)), morbidity composite in childbirth (AOR of 3.64 for obesity type III (95% CI: 2.13–6.24)), and macrosomia (AOR of 6.06 for obesity type III (95% CI: 3.17–11.60)), as compared with women with normoweight. Women with a higher BMI are more likely to develop complications during childbirth and macrosomia.

“…In our experience, weight loss in mid-or late pregnancy might predict anorexia symptoms (data not shown), while weight loss due to hyperemesis gravidarum is common in early pregnancy. A recent study reported that gestational weight gain had a greater effect than pre-pregnancy BMI on the increase in birth weight (Lima et al 2018), which should encourage underweight pregnant women to gain adequate weight and deliver healthy babies.…”

“…To express maternal low weight before and during pregnancy, pre-pregnancy body mass index (BMI) and gestational weight gain were adopted as potential confounders in the statistical analysis because they are associated with premature birth and infant size in the general population (Naeye and Tafari 1983;Fujiwara et al 2014;Enomoto et al 2016;Lima et al 2018). For the analysis of SDs from mean birth weight and mean head circumference at birth, both of which can have hereditary effects, maternal height was also adopted as a potential confounder (Naeye and Tafari 1983).…”

Eating disorders are common psychiatric disorders among women of reproductive age, and the prevalence of eating disorders has been increasing over time in Japan and other countries. The aim of the present study was to assess perinatal outcomes in maternal anorexia nervosa in Japan and to explore methods to improve perinatal outcomes. This study consists of a case series describing 13 single pregnancies of 11 women with a history of anorexia nervosa, and a cross-sectional study comparing 13 cases with 240 healthy controls. In the case group, nine cases conceived while underweight, including three who had fertility treatment. Anorexia symptoms during pregnancy were quite common, and pregnant smokers presented with extremely disturbed eating behaviors. In a cross-sectional study, premature birth and the standard deviations from the mean birth weight and mean head circumference at birth were evaluated as outcome measures. The adjusted odds ratios or the adjusted differences between two means for the above outcomes were estimated by two approaches: multivariate models and matching analysis. Statistical analysis showed that maternal anorexia nervosa was associated with an increased risk of premature birth and symmetric growth restriction mediated by low pre-pregnancy body mass index and poor gestational weight gain which were adjusted as confounders. Smoking during pregnancy was a potential indicator of abnormal eating behavior and could be predictive of poor perinatal outcomes. We therefore conclude that remission of anorexia nervosa before pregnancy could improve perinatal outcomes through both normal nutrition and smoking cessation. Fertility treatment while underweight is not recommended.
