Mother and baby risks associated with obesity in pregnancy: a systematic review of reviews

My name is Jamile Marchi and I am a second year PhD student from Brazil, supported by a Science Without Borders scholarship program, funded by the Brazilian Government . As a dietitian I am conducting the Nutrition strand of the MAMMI study (Maternal health and Maternal Mornidity in Ireland), aiming to identify the dietary and physical activity patterns of nulliparous women before and during pregnancy and analyse associations between diet and maternal outcomes. As part of my doctoral work, I (together with colleagues from Trinity College Dublin; City University London, UK; and University of Gothenburg, Sweden) have conducted a systematic review of systematic reviews on Mother and baby risks associated with obesity in pregnancy, that I will be presenting here at this Conference.

• Aim
To synthesize the findings from all systematic reviews conducted on maternal obesity in order to identify the risk of adverse outcomes on mother and baby.
• Background
Obesity in pregnancy is linked to a number of maternal and foetal complications. The prevalence of obesity in pregnancy (20-33%) has increased worldwide and has become a central public health issue.
• Search and review methodology
A protocol was developed a priori. Reviews that compared pregnant women of healthy weight with those who were obese (BMI >30), and reported on a health outcome for mother and/or baby, were eligible for inclusion. PubMed, CINAHL, Cochrane and Scopus databases were searched. Reviews were selected by inclusion criteria, and quality-assured using AMSTAR, independently by all authors, and checked by a second reviewer.
• Findings
Twenty-two systematic reviews, from a total of 573 original studies, met inclusion and quality criteria. Women with obesity in pregnancy were at increased risk of having an instrumental birth, caesarean section, surgical site infection, depression, gestational hypertension, diabetes mellitus and pre-eclampsia compared to women of healthy weight. Babies of women with obesity were at increased risk of preterm birth, being large-for-gestational-age, having fetal defects or congenital anomalies, perinatal death and neonatal death. Obesity in pregnancy was also associated with lower breastfeeding initiation rates and breastfeeding for a shorter time.
• Conclusions and Implications
This is the first review of reviews summarizing outcomes associated with maternal obesity. The results show the negative impact obesity in pregnancy has on maternal and neonatal outcomes. Women need support to lose weight prior to becoming pregnant, and to avoid excessive weight gain in pregnancy. Additional reviews investigating factors that help women to lose weight before pregnancy and maintain healthy weight during pregnancy are warranted.
