This study surveys 100 married and 100 unmarried primiparous mothers, attending the National Maternity Hospital, Dublin, with regard to their contraceptive practice, their planning of their pregnancy and the timing of their first antenatal visit. Nineteen per cent of the married women, but 64% of the unmarried women, had never used any contraceptive method. The contraceptive pill was the most popular method for both groups, but while three in five of the married women had at some time used the pill, only a little more than one in five of the unmarried women had ever used it. One quarter of the women who had used contraception reported that their pregnancy was the result of a failure in their contraceptive method. Eighty-nine per cent of the single group and 20% of the married had not planned their pregnancy. None of the married women, but almost a quarter of the single, delayed their first antenatal visit until after they were 20 weeks pregnant.
本研究调查了都柏林国家妇产医院的100名已婚初产妇和100名未婚初产妇，内容涉及她们的避孕措施、妊娠计划以及首次产前检查的时间。19%的已婚女性从未使用过任何避孕方法，而未婚女性的这一比例为64%。避孕药是两组中最常用的避孕方法，但已婚女性中有五分之三曾在某个时候使用过避孕药，而未婚女性中只有略多于五分之一的人曾使用过。在使用过避孕措施的女性中，四分之一的人表示她们的怀孕是避孕措施失败所致。单身组中89%的女性和已婚组中20%的女性没有计划怀孕。没有一名已婚女性，但几乎四分之一的单身女性将首次产前检查推迟到怀孕20周之后。
