We aimed to investigate the association of recreational physical activity before pregnancy with gestational diabetes mellitus (GDM). A cross-sectional study was performed using self-reported data from the Pregnancy Risk Assessment and Monitoring System. The study population included 1,052 self-reported GDM cases and 10,351 non-GDM controls. Recreational physical activity in the 3 months before pregnancy was recalled in postpartum structured interviews. Compared to women exercising less than 1 day per week, women who exercised >5 days per week in the 3 months before pregnancy had a 31% lower odds of GDM (adjusted odds ratio [aOR]: 0.69; 95% confidence interval [CI]: 0.46, 1.03). Women who exercised 1-4 days per week had a 7% lower odds of GDM (aOR: 0.93; 95%CI: 0.72, 1.19). We did not observe statistically significant associations between pre-pregnancy physical activity and GDM risk. However, the magnitude and direction of association are consistent with previous observational studies. These studies collectively suggest a role of physical activity in GDM prevention.
我们旨在研究妊娠前的娱乐性体力活动与妊娠期糖尿病（GDM）之间的关联。本研究采用妊娠风险评估和监测系统的自我报告数据进行了一项横断面研究。研究人群包括 1052 例自我报告的 GDM 病例和 10351 例非 GDM 对照。在产后的结构化访谈中，回忆了妊娠前 3 个月的娱乐性体力活动情况。与每周锻炼少于 1 天的女性相比，在妊娠前 3 个月每周锻炼超过 5 天的女性发生 GDM 的几率降低了 31%（调整后的优势比 [aOR]：0.69；95%置信区间 [CI]：0.46，1.03）。每周锻炼 1-4 天的女性发生 GDM 的几率降低了 7%（aOR：0.93；95%CI：0.72，1.19）。我们未观察到妊娠前体力活动与 GDM 风险之间存在统计学显著关联。然而，关联的幅度和方向与先前的观察性研究一致。这些研究共同表明体力活动在 GDM 预防中的作用。
