The aim was to evaluate the appropriateness of postal questionnaires in studies of spontaneous abortion in a general population.
Survey of spontaneous abortions by comparing diagnoses reported in questionnaires to information collected from hospital records and a discharge register.
The study took place in the general community.
The study involved a random sample of 1400 women born between 1935 and 1960, living in two towns in the south west of Sweden.
9% of spontaneous abortions among respondents were not reported in the questionnaire, and 31% were missing in the register; 80% of the spontaneous abortions reported in the questionnaire could be verified in hospital records, and a further 7% were mentioned in the records but not certified by a doctor; 97% of the diagnoses received by the women who had answered affirmatively to two complementary questions on spontaneous abortions could be found in the records.
Postal questionnaires can be used in epidemiological studies of spontaneous abortions, among a general population as well as among occupational groups.
旨在评估邮寄问卷调查在一般人群自然流产研究中的适用性。
通过将问卷调查中报告的诊断与从医院记录和出院登记册收集的信息进行比较，对自然流产进行调查。
该研究在一般社区中进行。
该研究涉及随机抽取的1400名出生于1935年至1960年之间、居住在瑞典西南部两个城镇的女性。
受访者中9%的自然流产未在问卷中报告，31%在登记册中缺失；问卷中报告的自然流产80%可在医院记录中得到证实，另有7%在记录中被提及但未经医生认证；对两个关于自然流产的补充问题回答为肯定的女性所接受的诊断中，97%可在记录中找到。
邮寄问卷可用于一般人群以及职业群体的自然流产流行病学研究。
