To the Editor Regarding the study findings reported by Dr Teede and colleagues,1 the association between the benefits of antenatal lifestyle interventions and specific pregnancy outcomes is a meaningful issue worthy of attention and discussion. Their meta-analysis of 117 studies with 34 546 women from 5 continents found that a structured diet and physical activity-based lifestyle interventions in prenatal care were associated with reduced gestational weight gain (GWG), as well as a decrease of adverse maternal and neonatal outcomes. The authors are to be praised for their research, which included a 2-stage search of the literature and a substantial number of pregnancies and sufficient statistical power to detect associations. However, we are concerned about the data presentation and interpretation.
