Interventions for preventing excessive weight gain during pregnancy

Diet or exercise, or both, during pregnancy reduce the risk of excessive gestational weight gain compared with usual care. However, diet and/or exercise may not be effective for reducing complications like pre-eclampsia, caesarean delivery, or macrosomia.

Comment:

Summary

A Cochrane review included 49 studies with a total of 11 444 subjects. Diet or exercise, or both, interventions reduced the risk of excessive gestationala weight gain on average by 20% overall (high-quality evidence) . Interventions involving low glycaemic load diets, supervised or unsupervised exercise only, or diet and exercise combined all led to similar reductions in the number of women gaining excessive weight in pregnancy. However, there was no significant difference between intervention and control groups with regard to pre-eclampsia, caesarean delivery, preterm birth overall, infant macrosomia, or poor neonatal outcomes including shoulder dystocia, neonatal hypoglycaemia, hyperbilirubinaemia, or birth trauma .
