Key result
Higher levels of moderate-to-vigorous intensity physical activity in the first trimester were associated with a 46% lower risk of gestational hypertension (adjusted OR 0.54) compared to the lowest levels.
Why the study?
To examine prospective associations between different intensities and different types of physical activity in early pregnancy and hypertensive disorders of pregnancy among Chinese women.
Does physical activity in early pregnancy reduce the risk of hypertensive disorders of pregnancy in Chinese women?
Cohort (n=6,820)

MVPA in early pregnancy was associated with lower gestational hypertension risk; hypothesis-generating for prevention and requires RCTs before changing prenatal advice.
We aimed to examine prospective associations between diff erent intensities and diff erent types of physical activity (PA) in early pregnancy and hypertensive disorders of pregnancy (HDP) among Chinese women. METHODS: A total of 6,820 pregnant women from the Tongji-Shuangliu Birth Cohort were included in this study. The pregnancy physical activity questionnaire (PPAQ) was used to assess PA, including household/caregiving, occupational, sports/exercise, and transportation activities in the first trimester of pregnancy. The diagnosis of HDP was collected, including gestational hypertension (GH) and preeclampsia (PE). Data were analyzed by unconditional multivariate logistic regression, and the odds ratio (OR) and 95% confi dence interval (CI) were calculated.

Qian Lü (2023) conducted a cohort in Hypertensive disorders of pregnancy (Gestational hypertension and Preeclampsia) (n=6,820). Moderate-to-vigorous intensity physical activity (MVPA) vs. Lowest tertile of MVPA was evaluated on Gestational hypertension (GH) (OR 0.54, 95% CI 0.31-0.96, p=P for trend=0.104). Higher levels of moderate-to-vigorous intensity physical activity in the first trimester were associated with a 46% lower risk of gestational hypertension (adjusted OR 0.54) compared to the lowest levels.
