Multidimensional retrospective studies were conducted into possible correlations between case histories of induced abortion and premature deliveries, on the one hand, and deliveries of "children with low birth weight", on the other, with reference being made to the ordinal number of birth. Included were 13,287 single newborns, after mothers with twins, stillbirths, and abortion records had been excluded. "Children with low birth weight" up to 2,500 g accounted for 5.4 per cent of these newborns. The investigation was complete, in that all newborns were examined in the obstetric department of the Regional Hospital of Schwerin, between 1969 and 1977. Records of premature delivery and induced abortion were found to play a great epidemiological role in the context of "children with low birth weight" up to 2,500 g, but the general trend for such children for the period under review had remained unaffected by the Free Medical Abortion Act of 1972. Nevertheless, mothers with previous abortions during the period studied contributed to a moderate rise of the total number of "newborns with low birth weight".
针对人工流产病史与早产之间、以及与“低体重儿”分娩之间可能存在的相关性进行了多维回顾性研究，同时参考了出生顺序。研究对象包括13287名单胎新生儿，已将怀有双胞胎、死产及流产记录的母亲排除在外。体重不足2500克的“低体重儿”占这些新生儿的5.4%。该调查是完整的，因为在1969年至1977年期间，施韦林地区医院产科对所有新生儿都进行了检查。结果发现，早产和人工流产记录在体重不足2500克的“低体重儿”情况中具有重要的流行病学意义，但在审查期间，此类儿童的总体趋势并未受到1972年《免费人工流产法》的影响。尽管如此，在研究期间有过流产史的母亲导致“低体重新生儿”总数略有上升。
