A telephone survey of 1,172 Hamilton County, Ohio residents indicated that for ever-married people, 25.1 per cent of those aged 18-45 and 33.8 per cent of those 30-45 had been sterilized. Blacks and Whites had comparable levels of sterilization but, among Blacks, female sterilization was over eight times as common as vasectomy, while for Whites, the ratio was 1.2. Catholics had only one-half the sterilization rate of Protestants. Race, sex, income, and education were all related to knowledge and attitudes toward vasectomy. The need for more information was a major reason cited for not having a vasectomy.
对俄亥俄州汉密尔顿县1172名居民进行的电话调查显示，在已婚人士中，18至45岁人群中有25.1%、30至45岁人群中有33.8%实施了绝育手术。黑人和白人的绝育水平相当，但在黑人中，女性绝育的普遍程度是输精管切除术的八倍多，而在白人中，这一比例为1.2。天主教徒的绝育率仅为新教徒的一半。种族、性别、收入和教育程度都与对输精管切除术的认知和态度有关。缺乏更多信息是未实施输精管切除术的主要原因。
