Doi L, et al. - In order to find out the relationship between high maternal weight status and complications during pregnancy and delivery, researchers applied data from 132,899 first-time singleton deliveries in Scotland between 2008 and 2015. This study compared women with overweight and obesity, with women with normal weight. They investigated correlations between maternal BMI and complications during pregnancy and delivery. The main outcome measures were gestational diabetes, gestational hypertension, pre-eclampsia, placenta praevia, placental abruption, induction of labour, elective and emergency caesarean sections, pre-term delivery, post-term delivery, low Apgar score, small for gestational age and large for gestational age. It was noted that in Scotland, women with overweight and obesity are at greater odds of adverse pregnancy and delivery outcomes. The odds of these conditions grow with increasing BMI. The results suggested that health professionals should be allowed and trained to deliver promising dietary and lifestyle interventions to women at risk of overweight and obesity before conception and control excessive weight gain in pregnancy.
