Abstract

A hospital discharge registry covering all general hospitals in Finland was used in the study of spontaneous abortions. Spontaneous abortions were analysed by the women's occupation and socio-economic class for 1973-75 inclusive. The risk of spontaneous abortion increased from social class 1 to 4 by about 50%. The occupational groups with an increased frequency of spontaneous abortions included industrial and construction work, agriculture, forestry and fishing, sales, transport and communication, services, and students and trainees. Decreased frequency of spontaneous abortions was noted among housewives, and in managerial and clerical occupations. The results suggest that socio-economic factors contribute to the rate of spontaneous abortions analogous to their known adverse effects on pre-term birth, birth weight and perinatal mortality.

摘要

在一项关于自然流产的研究中，使用了涵盖芬兰所有综合医院的出院登记系统。对1973年至1975年（含）期间自然流产情况按女性职业和社会经济阶层进行了分析。自然流产风险从社会阶层1到4增加了约50%。自然流产发生率增加的职业群体包括工业和建筑工作、农业、林业和渔业、销售、运输和通信、服务业以及学生和实习生。家庭主妇以及管理和文职职业的自然流产发生率较低。结果表明，社会经济因素对自然流产率有影响，类似于它们对早产、出生体重和围产期死亡率已知的不利影响。
