Gestational hypertensive disorders, including gestational hypertension and preeclampsia, are one of the leading causes of maternal morbidity and mortality. The aim of our study was to evaluate the effect of exercise during pregnancy on the risk of gestational hypertensive disorders MATERIAL AND METHODS: Electronic databases were searched from their inception to February 2017. Selection criteria included only randomized controlled trials of uncomplicated pregnant women assigned before 23 weeks to an aerobic exercise regimen or not. The summary measures were reported as relative risk (RR) with 95% confidence intervals (CI). The primary outcome was the incidence of gestational hypertensive disorders, defined as either gestational hypertension or preeclampsia RESULTS: Seventeen trials, including 5,075 pregnant women, were analyzed. Of them, seven contributed data to quantitative meta-analysis for the primary outcome. Women who were randomized in early pregnancy to aerobic exercise for about 30-60 minutes 2-7 times per week had a significant lower incidence of gestational hypertensive disorders (5.9% vs 8.5%; RR 0.70, 95% CI 0.53 to 0.83; 7 studies, 2,517 participants), specifically a lower incidence of gestational hypertension (2.5% vs 4.6%; RR 0.54, 95% CI 0.40 to 0.74; 16 studies, 4,641 participants) compared to controls. The incidence of preeclampsia (2.3% vs 2.8%; RR 0.79, 95% CI 0.45 to 1.38; 6 studies, 2,230 participants) was similar in both groups. The incidence of cesarean delivery was decreased by 16% in the exercise group CONCLUSIONS: Aerobic exercise for about 30-60 minutes 2-7 times per week during pregnancy, as compared to being more sedentary, is associated with a significantly reduced risk of gestational hypertensive disorders overall, gestational hypertension, and cesarean delivery.

Abstract
Gestational hypertensive disorders, including gestational hypertension and preeclampsia, are one of the leading causes of maternal morbidity and mortality. The aim of our study was to evaluate the effect of exercise during pregnancy on the risk of gestational hypertensive disorders MATERIAL AND METHODS: Electronic databases were searched from their inception to February 2017. Selection criteria included only randomized controlled trials of uncomplicated pregnant women assigned before 23 weeks to an aerobic exercise regimen or not. The summary measures were reported as relative risk (RR) with 95% confidence intervals (CI). The primary outcome was the incidence of gestational hypertensive disorders, defined as either gestational hypertension or preeclampsia RESULTS: Seventeen trials, including 5,075 pregnant women, were analyzed. Of them, seven contributed data to quantitative meta-analysis for the primary outcome. Women who were randomized in early pregnancy to aerobic exercise for about 30-60 minutes 2-7 times per week had a significant lower incidence of gestational hypertensive disorders (5.9% vs 8.5%; RR 0.70, 95% CI 0.53 to 0.83; 7 studies, 2,517 participants), specifically a lower incidence of gestational hypertension (2.5% vs 4.6%; RR 0.54, 95% CI 0.40 to 0.74; 16 studies, 4,641 participants) compared to controls. The incidence of preeclampsia (2.3% vs 2.8%; RR 0.79, 95% CI 0.45 to 1.38; 6 studies, 2,230 participants) was similar in both groups. The incidence of cesarean delivery was decreased by 16% in the exercise group CONCLUSIONS: Aerobic exercise for about 30-60 minutes 2-7 times per week during pregnancy, as compared to being more sedentary, is associated with a significantly reduced risk of gestational hypertensive disorders overall, gestational hypertension, and cesarean delivery.
