Pastorino S, et al. - Researchers performed individual level meta-analysis to examine how leisure-time physical activity (LTPA) during early is related to late pregnancy and newborn anthropometric outcomes. Analyzing eight population-based studies (seven European and one US) comprising 72 694 participants, they identified a modest inverse association of late, but not early, gestation maternal moderate to vigorous physical activity (MVPA), vigorous activity, and LTPA energy expenditure, with birth weight, large-for-gestational age (LGA), macrosomia, and ponderal index, without heterogeneity.
