The Cardiff Cervical Cytology Study began in 1965. Its primary aim was to evaluate screening for neoplasia of the cervix uteri. The study population was all ever-married women, aged 25--69, resident within the Cardiff City area. The basic objective was that all such women should be screened three times. The population was enumerated by house-to-house visiting of the entire city and a register of eligible women was compiled. The first round of visiting finished early in 1971. The defined population numbered 70 869, of whom 45 915 (65%) had had one or more tests. The method of defining the population is described and details are given of the initial response rates in respect of the major demographic factors. The response rate varied with age and with social class. It declined from 92% in the age group 25--29 to 26% in the age group 65--69, and from 81% in Social Class I to 52% in Social Class V. The response was 5% to 10% lower among widowed, divorced, and separated women than among married women but was independent of age at first marriage and age at first pregnancy. Nulliparae showed a lower response rate than multiparae.
加的夫宫颈细胞学研究始于1965年。其主要目的是评估子宫颈肿瘤的筛查情况。研究对象为居住在加的夫市地区、年龄在25至69岁之间的所有已婚妇女。基本目标是对所有这类妇女进行三次筛查。通过逐户走访全市对人口进行了普查，并编制了符合条件妇女的登记册。第一轮走访于1971年初结束。确定的人口为70869人，其中45915人（65%）接受了一次或多次检查。描述了确定人口的方法，并给出了关于主要人口因素的初始应答率的详细信息。应答率随年龄和社会阶层而变化。从25至29岁年龄组的92%下降到65至69岁年龄组的26%，从社会阶层I的81%下降到社会阶层V的52%。丧偶、离婚和分居妇女的应答率比已婚妇女低5%至10%，但与初婚年龄和初孕年龄无关。未生育妇女的应答率低于已生育妇女。
