我们对5,144名孕妇进行了一项前瞻性研究，探讨了体力消耗与自然流产的关系。在第一个三个月的访谈中，我们获得了关于就业和工作和家庭中的体力活动以及其他自然流产的潜在风险因素的数据。我们测量的消耗如下：工作时间，工作时站立和弯腰，休息时间，做家务或庭院工作的时间;轮班工作;在工作或在家举重超过15磅的次数;在家照顾的5岁以下儿童人数。没有一项运动量与总体自然流产风险增加明显相关。此外，工作和在家的身体活动与风险增加无关。对于有两次或两次以上自然流产史的女性，每天站立工作超过7小时与调整后的比值比（OR）为4.3 [95%置信限（CL）= 1.6，11.7]相关，而站立工作7小时或更少与调整后的OR为1.7（95% CL = 1.1，2.6）相关。没有这样的历史，谁站在工作超过7小时的妇女有一个调整或接近团结。
We examined the relation of physical exertion to spontaneous abortion in a prospective study of 5,144 pregnant women. In a first trimester interview, we obtained data on employment and physical activity at work and at home, as well as other potential risk factors for spontaneous abortion. We measured exertion as follows: time spent working, standing and bending at work, hours between breaks, and hours spent doing housework or yardwork; shift worked; number of times lifted weights of more than 15 pounds at work or at home; number of children under age 5 years cared for at home. None of the exertion measures was appreciably associated with an increased risk of spontaneous abortion overall. In addition, physical activity at work and at home combined was not related to increased risk. For women with a history of two or more spontaneous abortions, standing at work more than 7 hours per day was associated with an adjusted odds ratio (OR) of 4.3 [95% confidence limits (CL) = 1.6, 11.7], whereas standing at work for 7 hours or less was associated with an adjusted OR of 1.7 (95% CL = 1.1, 2.6). Women without such a history who stood more than 7 hours at work had an adjusted OR near unity.
