To examine the association of physical activity on maternal-fetal circulation measured by uterine and umbilical artery Doppler flow velocimetry waveforms.
Participants included 781 pregnant women with Doppler ultrasounds of the uterine and umbilical artery and who self-reported past week physical activity. Linear and generalized estimating equation regression models were used to examine these associations.
Moderate-to-vigorous total and recreational activity were associated with higher uterine artery pulsatility index (PI) and an increased risk of uterine artery notching as compared with reporting no total or recreational physical activity, respectively. Moderate-to-vigorous work activity was associated with lower uterine artery PI and a reduced risk of uterine artery notching as compared with no work activity. No associations were identified with the umbilical circulation measured by the resistance index.
In this epidemiologic study, recreational and work activity were associated with opposite effects on uterine artery PI and uterine artery notching, although associations were modest in magnitude.
通过子宫和脐动脉多普勒血流速度波形来检测母体-胎儿循环中的体力活动与体力活动之间的关系。
参与者包括 781 名接受过子宫和脐动脉多普勒超声检查且自述过去一周有体力活动的孕妇。采用线性和广义估计方程回归模型来检验这些关联。
与报告没有总活动或休闲活动相比，适度到剧烈的总活动和休闲活动与较高的子宫动脉搏动指数（PI）和增加的子宫动脉切迹风险相关。与没有工作活动相比，适度到剧烈的工作活动与较低的子宫动脉 PI 和降低的子宫动脉切迹风险相关。阻力指数测量的脐循环没有发现关联。
在这项流行病学研究中，休闲活动和工作活动与子宫动脉 PI 和子宫动脉切迹呈相反的影响，但关联的幅度不大。
