Unintended pregnancy, an important public health issue, disproportionately affects minority populations. Yet, the independent associations of race, ethnicity and other characteristics with contraceptive choice have not been well studied.
Racial and ethnic disparities in contraceptive use among 3,277 women aged 18-44 and at risk for unintended pregnancy were assessed using 2006-2008 data from of the California Women's Health Survey. Sequential logistic regression analyses were used to examine the independent and cumulative associations of racial, ethnic, demographic and socioeconomic characteristics with method choice.
Differences in contraceptive use persisted in analyses controlling for demographic and socioeconomic characteristics. Blacks and foreign-born Asians were less likely than whites to use high-efficacy reversible methods-that is, hormonals or IUDs (odds ratio, 0.5 for each). No differences by race or ethnicity were found specifically for IUD use in the full model. Blacks and U.S.-born Hispanics were more likely than whites to choose female sterilization (1.9 and 1.7, respectively), while foreign-born Asians had reduced odds of such use (0.4). Finally, blacks and foreign-born Asians were less likely than whites to rely on male sterilization (0.3 and 0.1, respectively).
Socioeconomic factors did not explain the disparities in method choice among racial and ethnic groups. Intervention programs that focus on improving contraceptive choice among black and, particularly, Asian populations need to be developed, as such programs have the potential to reduce the number of unintended pregnancies that occur among these high-risk groups.
意外怀孕是一个重要的公共卫生问题,它不成比例地影响着少数族裔。然而,种族、民族和其他特征与避孕方法选择的独立关联尚未得到很好的研究。
利用 2006-2008 年加利福尼亚妇女健康调查的数据,评估了 3277 名年龄在 18-44 岁且有意外怀孕风险的妇女中种族和民族在避孕措施使用方面的差异。采用序贯逻辑回归分析,考察种族、民族、人口统计学和社会经济特征与方法选择的独立和累积关联。
在控制人口统计学和社会经济特征的分析中,避孕方法的使用差异仍然存在。与白人相比,黑人以及出生于亚洲其他国家的女性使用高效可逆方法(即激素或宫内节育器)的可能性较小(每种方法的比值比为 0.5)。在全模型中,未发现特定种族或族裔与宫内节育器使用之间存在差异。与白人相比,黑人以及出生于美国的西班牙裔更有可能选择女性绝育(分别为 1.9 和 1.7),而出生于亚洲其他国家的女性选择这种方法的可能性较小(0.4)。最后,与白人相比,黑人以及出生于亚洲其他国家的女性更不可能依赖男性绝育(分别为 0.3 和 0.1)。
社会经济因素并不能解释不同种族和族裔群体在方法选择方面的差异。需要制定针对黑人和特别是亚裔人群改善避孕方法选择的干预计划,因为这些计划有可能减少这些高风险群体中意外怀孕的数量。
