BACKGROUND: a high body mass index (BMI) during pregnancy has been associated with an increased risk of complications and adverse outcomes for both mother and infant. OBJECTIVES: to analyse the main adverse maternal and neonatal outcomes associated with maternal excess weight and obesity. DESIGN: retrospective epidemiological study. SETTING AND PARTICIPANTS: data extrapolated from the Birth Attendance Certificate information flow of the Autonomous Province of Trento (Northern Italy) between 2015 and 2019. A total of 20,756 women with data regarding maternal height and weight at the start of pregnancy were included in the analysis. MAIN OUTCOME MEASURES: gestational outcome variables studied were gestational diabetes, hypertensive disorders, premature birth, and still births. Outcomes considered during labour and delivery were type of delivery, induction, episiotomy and post-partum haemorrhage. Neonatal outcomes were birth weight, Apgar score, need for resuscitation, and hospitalisation in the neonatal intensive care unit (NICU). Lastly, exclusive breastfeeding at discharge was analysed. RESULTS: considering the population of pregnant women, 68.3% of women were classified as normal-weight, 9.5% as underweight, 16.0% as overweight, and 6.3% as obese. Maternal excess weight and obesity were seen to be associated with an increased risk of gestational diabetes, gestational hypertension, preeclampsia, caesarean section, induction, post-partum bleeding, foetal macrosomia, and the need for neonatal resuscitation and hospitalisation in the NICU. Infants born to overweight and obese mothers were also less likely to be breastfed. CONCLUSIONS: excess weight and obesity are important risk factors for health and contribute to the onset of complications during pregnancy and adverse perinatal and long-term outcomes. Programming and implementing public health promotion schemes aimed at preventing excessive weight gain in the reproductive age could significantly improve maternal and foetal health.
