In Brazil, the effectiveness of preventive public heath programs and actions is rarely evaluated. A cross-sectional study was thus performed in a population-based sample focused on several health characteristics of adults living in Pelotas, Rio Grande do Sul, Brazil. The study aimed to measure temporal trends in coverage of Pap smear testing in the city. The authors studied the factors associated with failure of women to submit to a Pap smear. An updated Pap smear was defined as one performed in the previous 3 years. The sample consisted of 1,122 women ages 20 to 69 years, 72.2% of whom had an updated Pap smear, 16.6% of whom were behind schedule for testing, and 11.2% of whom had never had a Pap smear. Risk factors for never having a test were low socioeconomic status and old age. Logistic regression showed an independent effect of social class, low family income, age, skin color, marital status, and no medical appointment in the previous year. However, the effect of chronic diseases disappeared in logistic regression. The authors compare the results of the study conducted in 1992 with the present. Pap smear coverage increased from 65.0% to 72.2% (1992 to 1999/2000) in the city, yet such figures had still not ensured the effectiveness of the program for uterine cervical cancer prevention.
在巴西，预防性公共卫生项目及行动的成效很少得到评估。因此，针对巴西南里奥格兰德州佩洛塔斯市成年人的若干健康特征，开展了一项基于人群样本的横断面研究。该研究旨在衡量该市巴氏涂片检查覆盖率的时间趋势。作者研究了女性未进行巴氏涂片检查的相关因素。近期的巴氏涂片检查定义为在过去3年内进行的检查。样本包括1122名年龄在20至69岁之间的女性，其中72.2%进行了近期巴氏涂片检查，16.6%的检查时间滞后，11.2%从未进行过巴氏涂片检查。从未接受检查的风险因素包括社会经济地位低和年龄大。逻辑回归显示，社会阶层、家庭收入低、年龄、肤色、婚姻状况以及上一年未预约就诊具有独立影响。然而，慢性病的影响在逻辑回归中消失。作者将1992年开展的研究结果与当前结果进行了比较。该市的巴氏涂片检查覆盖率从65.0%提高到了72.2%（1992年至1999/2000年），但这些数字仍未确保预防子宫颈癌项目发挥成效。
