Some characteristics of the working activity of pregnant women were investigated during statistical analysis of data pertaining to 6166 naturally terminated pregnancies in the Gottwaldov district (1981-1983). The threatening element from the aspect of spontaneous abortions in the first trimester is work done during most of the shift in a standing position without movement. There also the highest incidence of small-for-age and hypotrophic foetuses was found. Work involving constant movement is a risk and may lead to premature delivery. Manipulation with loads threatens pregnancy by reproductive losses (in particular a higher incidence of haemorrhage during the first trimester) and by prematurity. Social tension at the place of work also threatens pregnancy - at conflict in work places a significantly increased risk was proved. It was also proved that it is important to respect medical recommendation to transfer pregnant women to other work. As to associated factors, commuting was investigated and its adverse effect is particularly apparent when the distance is more than 25 km.
在对哥特瓦尔多夫地区（1981 - 1983年）6166例自然终止妊娠的数据进行统计分析期间，对孕妇工作活动的一些特征进行了调查。从孕早期自然流产的角度来看，威胁因素是大部分轮班时间都站着不动地工作。在这种情况下，还发现了年龄过小和发育不良胎儿的发生率最高。涉及持续走动的工作存在风险，可能导致早产。搬运重物会因生殖损失（特别是孕早期出血发生率较高）和早产而危及妊娠。工作场所的社会紧张局势也会危及妊娠——在工作场所发生冲突时，已证明风险会显著增加。还证明了遵守将孕妇调至其他工作岗位的医疗建议很重要。关于相关因素，对通勤情况进行了调查，当距离超过25公里时，其不利影响尤为明显。
