In 2003, a population-based cross-sectional study was conducted in the urban area of São Leopoldo, Rio Grande do Sul, Brazil. The sample included 867 sexually active women from 20 to 60 years of age. The objective was to describe the use of contraceptive methods. Data were collected using a standardized questionnaire. The study analyzed the prevalence of contraceptive use and socioeconomic variables in women reporting an active sex life (84.5%), stratified by age groups. Some 627 (61.1%) women reported use of contraceptive methods. In the 20-49-year old group, 48.8% reported using oral contraceptives, 18.7% tubal ligation, 17.3% condoms, and 7.3% IUDs. In the 50-60-year old group, the most widely used method was tubal ligation (79.6%). Regarding tubal ligation, the schooling variable showed a linear trend, that is, women with less schooling showed a higher prevalence. Prevalence of oral contraception was higher in low-income women.
2003年，在巴西南里奥格兰德州圣莱奥波尔多市区开展了一项基于人群的横断面研究。样本包括867名年龄在20至60岁之间的性活跃女性。目的是描述避孕方法的使用情况。通过标准化问卷收集数据。该研究分析了报告有活跃性生活的女性（84.5%）中避孕方法的使用情况及社会经济变量，并按年龄组进行分层。约627名（61.1%）女性报告使用了避孕方法。在20至49岁年龄组中，48.8%的女性报告使用口服避孕药，18.7%进行输卵管结扎，17.3%使用避孕套，7.3%使用宫内节育器。在50至60岁年龄组中，使用最广泛的方法是输卵管结扎（79.6%）。关于输卵管结扎，受教育程度变量呈现线性趋势，即受教育程度较低的女性患病率较高。低收入女性口服避孕药的患病率较高。
