To quantify moderate-to-vigorous physical activity (MVPA) at postpartum in women with recent gestational diabetes mellitus, using an accelerometer and self-reported measurements from participants of the LINDA-Brasil study.
In a cross-sectional sample (n = 391), MVPA was assessed via a waist-worn accelerometer and the international physical activity questionnaire (IPAQ), focusing on leisure time and commuting domains.
The median postpartum period was 7.3 months (interquartile range [IQR]: 4.0-14.0). When restricted to 10-minute bouts, device-measured MVPA was 22.31 minutes/week (IQR: 0-65.8), whereas total time spent on MVPA was 213.8 minutes/week (IQR: 137.7-320.0). Higher education and pregnancy complications were associated with lower device-based MVPA. Self-reported leisure-time MVPA in 10-minute bouts was 0 minutes/week (IQR: 0-0). However, including commuting time, it increased to 90 minutes/week (IQR: 10.0-210.0). Based on total device-measured MVPA, 71.6% (CI 66.9-76.0) met the recommended 150 minutes/week. This proportion decreased to 8.4% (95% CI: 5.9-11.7) in 10-minute bouts MVPA. Based on the IPAQ, 7.4% (95% CI: 5.0-10.5) reached the guideline through leisure-time activity and 26.8% (95% CI: 22.5-31.5) through combined leisure and commuting.
Women with gestational diabetes mellitus at postpartum were highly active based on device-measured MVPA. Nevertheless, applying the 10-minute bout reduced these estimates across devices and self-reported measurements. These findings provide crucial information for public policies addressing this high-risk population.
使用加速度计以及来自LINDA-巴西研究参与者的自我报告测量数据，对近期患有妊娠期糖尿病的女性产后的中度至剧烈身体活动（MVPA）进行量化。
在一个横断面样本（n = 391）中，通过佩戴在腰部的加速度计和国际身体活动问卷（IPAQ）评估MVPA，重点关注休闲时间和通勤领域。
产后中位时间为7.3个月（四分位间距[IQR]：4.0 - 14.0）。当限制为10分钟的时间段时，设备测量的MVPA为每周22.31分钟（IQR：0 - 65.8），而MVPA的总时长为每周213.8分钟（IQR：137.7 - 320.0）。高等教育和妊娠并发症与基于设备的较低MVPA相关。自我报告的10分钟时间段的休闲时间MVPA为每周0分钟（IQR：0 - 0）。然而，将通勤时间包括在内后，增加到每周90分钟（IQR：10.0 - 210.0）。基于设备测量的MVPA总量，71.6%（CI 66.9 - 76.0）达到了每周150分钟的推荐量。在10分钟时间段的MVPA中，这一比例降至8.4%（95% CI：5.9 - 11.7）。根据IPAQ，7.4%（95% CI：5.0 - 10.5）通过休闲时间活动达到指南标准，26.8%（95% CI：22.5 - 31.5）通过休闲和通勤相结合达到标准。
基于设备测量的MVPA，产后患有妊娠期糖尿病的女性身体活动水平较高。然而，采用10分钟时间段的标准会降低基于设备和自我报告测量的这些估计值。这些发现为针对这一高危人群的公共政策提供了关键信息。
