Abstract:
Objective:To systematically estimate the effectiveness of physical activity intervention and Borg perceived exertion on the prevention of gestational diabetes mellitus (GDM), and to provide references for physical activity management during pregnancy.Methods:Databases such as PubMed, Cochrane Library Central Register of Controlled Trails, EMBASE, Scopus, CNKI and Wanfang were searched to collect randomized controlled trials (RCT) focusing on the effect of physical activity intervention on glucose control and pregnancy outcomes in pregnant women. The primary outcome was the incidence of GDM. The secondary outcomes included the 2 hour oral glucose tolerance test (2 h OGTT), gestational weight gain, gestational week of delivery, and neonatal weight. The statistical analysis was performed by R 4.0.2 software. The quality of the literatures was evaluated based on the Cochrane Risk of bias tool.Results:A total of 14 RCTs involving 4 509 participants were included in this meta-analysis. The results of meta-analysis showed that the incidence of GDM ( RR=0.74, 95% CI=0.59-0.93, P<0.01), 2 h OGTT (MD=-0.27, 95% CI=-0.48--0.07, P<0.01), and gestational weight gain (MD=-1.04, 95% CI=-1.91--0.18, P=0.02) in the experimental group were all significantly lower than those in control group, while the neonatal weight (MD=-27.43, 95% CI=-58.77-3.92, P=0.09) and gestational week of delivery (MD=-0.18, 95% CI=-0.93-0.57, P=0.64) showed no significant difference between the two groups. Subgroup analysis showed that Borg rating scale of perceived exertion scored higher than 12 ( RR=0.64, 95% CI=0.46-0.89, P<0.01), physical activity conducted in groups ( RR=0.66, 95% CI=0.46-0.94, P=0.02), intervention organized by fitness specialist ( RR=0.73, 95% CI=0.56-0.95, P=0.02) were associated with the decreased risk of GDM. In addition, the meta-regression result showed that total intervention time more than 2 hours per week (correlation coefficient=-1.06, 95% CI=-1.86--0.27, P<0.01) was the main source of study heterogeneity. Conclusions:Physical activity during pregnancy with Borg rating scale of perceived exertion scored higher than 12 had a positive effect on reducing the incidence of GDM.
