| Consumer Summary: | WHAT IS ALREADY KNOWN ON THIS TOPIC: Gestational diabetes mellitus (GDM), gestational hypertension (GH) and pre-eclampsia (PE) are associated with short and long-term health issues for mother and child; prevention of these complications is therefore critically important. Exercise is a cornerstone for prevention and treatment of hypertension and diabetes in general populations; however, the effectiveness of exercise in prevention during pregnancy is poorly understood. WHAT ARE THE NEW FINDINGS: Exercise-only interventions reduced the odds of developing GDM by 38%, GH by 39% and PE by 41%. To achieve at least a 25% reduction in the odds of developing GDM, PE and GH, pregnant women need to accumulate at least 600 MET-min/week of moderate-intensity exercise (eg, 140 min of brisk walking, water aerobics, stationary cycling or resistance training). |
| Abstract: | OBJECTIVE: Gestational diabetes mellitus (GDM), gestational hypertension (GH) and pre-eclampsia (PE) are associated with short and long-term health issues for mother and child; prevention of these complications is critically important. This study aimed to perform a systematic review and meta-analysis of the relationships between prenatal exercise and GDM, GH and PE. DESIGN: Systematic review with random effects meta-analysis and meta-regression. DATA SOURCES: Online databases were searched up to 6 January 2017. STUDY ELIGIBILITY CRITERIA: Studies of all designs were included (except case studies) if published in English, Spanish or French, and contained information on the Population (pregnant women without contraindication to exercise), Intervention (subjective or objective measures of frequency, intensity, duration, volume or type of exercise, alone ("exercise-only") or in combination with other intervention components (eg, dietary; "exercise plus co-intervention")), Comparator (no exercise or different frequency, intensity, duration, volume and type of exercise) and Outcomes (GDM, GH, PE). RESULTS: A total of 106 studies (n = 273 182) were included. 'Moderate' to 'high'-quality evidence from randomised controlled trials revealed that exercise-only interventions, but not exercise plus cointerventions, reduced odds of GDM (n = 6,934; OR 0.62, 95% CI 0.52 to 0.75), GH (n = 5,316; OR 0.61, 95% CI 0.43 to 0.85) and PE (n = 3,322; OR 0.59, 95% CI 0.37 to 0.9) compared with no exercise. To achieve at least a 25% reduction in the odds of developing GDM, PE and GH, pregnant women need to accumulate at least 600 MET-min/week of moderate-intensity exercise (eg, 140 min of brisk walking, water aerobics, stationary cycling or resistance training). SUMMARY/CONCLUSIONS: In conclusion, exercise-only interventions were effective at lowering the odds of developing GDM, GH and PE. Reproduced with permission from the BMJ Publishing Group.
