To assess the impact of physical activity on the gestational age at delivery in women performing physical tasks in their jobs during pregnancy.
Qualified nurses at 15 weeks of pregnancy were asked through a questionnaire to describe the tasks in their regular job, the physical activities involved, and their exposure to other occupational stressors. The physical activities to be identified were walking, standing, lifting, stooping, squatting, and sitting.
A high degree of daily physical work load during pregnancy seemed to be a significant predictor for the gestational age at delivery, whereas chemical and infectious agents were not.
Physical work load during pregnancy should be diminished to avoid adverse effects on gestational age at delivery.
评估孕期从事体力劳动的女性身体活动对分娩孕周的影响。
通过问卷调查询问怀孕15周的合格护士，以描述其日常工作中的任务、所涉及的身体活动以及她们接触其他职业压力源的情况。需确定的身体活动包括行走、站立、提举、弯腰、下蹲和坐着。
孕期较高的日常体力工作量似乎是分娩孕周的一个重要预测因素，而化学和感染因素则不是。
应减少孕期的体力工作量，以避免对分娩孕周产生不利影响。
