A cross-sectional population-based study was conducted to investigate the prevalence of anemia and associated factors in adult women. A representative sample was selected with 312 women aged 20 to 60 in São Leopoldo, Rio Grande do Sul State, Brazil. The bivariate analyses included the chi-squared test, prevalence ratios, and 95% confidence intervals. Poisson regression was used to adjust effects in the multivariate analyses. Anemia prevalence was 19.2% (95%CI: 14.8-23.6) for all women in the sample. The highest prevalence was in black women (54%). After controlling for confounding factors, the risk of anemia in black women was three times that of whites (PR = 3.17; 95%CI: 1.85-5.41; p < 0.001). A protective effect against anemia (PR = 0.44; 95%CI: 0.19-1.07; p = 0.07) was found in women over 50 as compared to younger women (20-29 years). These findings suggest the need for public health policies for anemia prevention in black women.
开展了一项基于人群的横断面研究，以调查成年女性贫血症的患病率及相关因素。在巴西南里奥格兰德州圣莱奥波尔多市，选取了312名年龄在20至60岁之间的具有代表性的女性样本。双变量分析包括卡方检验、患病率比和95%置信区间。在多变量分析中使用泊松回归来调整效应。样本中所有女性的贫血患病率为19.2%（95%置信区间：14.8 - 23.6）。患病率最高的是黑人女性（54%）。在控制混杂因素后，黑人女性患贫血的风险是白人女性的三倍（患病率比 = 3.17；95%置信区间：1.85 - 5.41；p < 0.001）。与年轻女性（20 - 29岁）相比，50岁以上女性对贫血有保护作用（患病率比 = 0.44；95%置信区间：0.19 - 1.07；p = 0.07）。这些发现表明需要制定针对黑人女性预防贫血的公共卫生政策。
