Abstract
OBJECTIVE: To investigate the effect of supervised moderate to vigorous exercise on gestational weight gain, its related risks (gestational diabetes [GD]), macrosomia, and type of delivery), and the preventive effects on women who exceed the weight gain recommendations. PATIENTS AND METHODS: We conducted a single-center, 2-armed, randomized controlled trial between October 1, 2009, and June 30, 2011, in which 678 women were assessed and 345 were randomized by a central computer system to an intervention group (N=115) or a standard care group (N=230). The intervention exercise program consisted of 70 to 78 sessions (24 weeks, 3 times per week, 60-65 minutes per session, moderate to vigorous intensity). The standard care group received usual care. Excessive gestational weight (EGW) gain was calculated on the basis of the 2009 Institute of Medicine (IOM) recommendations. RESULTS: Of the 345 women randomized for treatment, 44 were lost to follow-up, leaving 301 women for analysis (intervention, 100; standard care, 201). Fewer women in the intervention group exceeded IOM recommendations (22 [22.0%] vs 69 [34.3%]; P=.03), including overweight and obese women (15 of 35 [42.9%] vs 40 of 50 [80.0%]; P=.001). Analysis of women exceeding weight recommendations revealed that the 3 main related risks were directly related to EGW gain in the standard care group (GD, P=.003; macrosomia, P<.001; type of delivery, P<.001) but not in the intervention group (GD, P>.99; macrosomia, 0%; type of delivery, P=.46). CONCLUSION:Supervised moderate to vigorous exercise performed throughout gestation was effective in the prevention of EGW gain even for women with a pregestational body mass index greater than 25 kg/m2. It also prevented its related risks (GD, macrosomia, and type of delivery) including for women exceeding the IOM recommendations, so we suggest that being active outweighs the effect of possible weight gain. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01477372.
