Minority women are more likely than white women to choose tubal sterilization as a contraceptive method. Disparities in rates of unintended pregnancy may help explain observed racial/ethnic differences in sterilization, but this association has not been investigated.
To examine the associations among race/ethnicity, unintended pregnancy, and tubal sterilization.
Cross-sectional analysis of data from a nationally representative sample of women aged 15-44 years [65.7% white, 14.8% Hispanic, and 13.9% African American (AA)] who participated in the 2002 National Survey of Family Growth.
Race/ethnicity, history of unintended pregnancy, and tubal sterilization. A logistic regression model was used to estimate the effect of race/ethnicity on unintended pregnancy while adjusting for socio-demographic variables. A series of logistic regression models was then used to examine the role of unintended pregnancy as a confounder for the relationship between race/ethnicity and sterilization.
Overall, 40% of white, 48% of Hispanic, and 59% of AA women reported a history of unintended pregnancy. After adjusting for socio-demographic variables, AA women were more likely (OR: 2.0; 95% CI: 1.6-2.4) and Hispanic women as likely (OR: 1.0; 95% CI: 0.80-1.2) as white women to report unintended pregnancy. Sterilization was reported by 29% of women who had ever had an unintended pregnancy compared to 7% of women who reported never having an unintended pregnancy. In unadjusted analysis, AA and Hispanic women had significantly higher odds of undergoing sterilization (OR: 1.5; 95% CI: 1.3-1.9 and OR: 1.4; 95% CI: 1.2-1.7, respectively). After adjusting for unintended pregnancy, this relationship was attenuated and no longer significant (OR: 1.2; 95% CI: 0.95-1.4 for AA women and OR: 1.3; 95% CI: 1.0-1.6 for Hispanic women).
Minority women, who more frequently experience unintended pregnancy, may choose tubal sterilization in response to prior experiences with an unintended pregnancy.
少数民族女性比白人女性更倾向于选择输卵管结扎作为避孕方法。意外怀孕率的差异可能有助于解释观察到的种族/民族之间在绝育方面的差异，但这一关联尚未得到调查。
研究种族/民族、意外怀孕和输卵管结扎之间的关系。
对 2002 年全国家庭增长调查中年龄在 15-44 岁之间的具有代表性的白人（65.7%）、西班牙裔（14.8%）和非裔美国人（13.9%）女性数据进行的横断面分析。
种族/民族、意外怀孕史和输卵管结扎术。使用逻辑回归模型估计种族/民族对意外怀孕的影响，同时调整社会人口统计学变量。然后使用一系列逻辑回归模型来研究意外怀孕作为种族/民族与绝育关系的混杂因素的作用。
总体而言，40%的白人、48%的西班牙裔和 59%的非裔美国女性报告有意外怀孕史。调整社会人口统计学变量后，非裔美国女性更有可能（比值比：2.0；95%置信区间：1.6-2.4），西班牙裔女性与白人女性一样可能（比值比：1.0；95%置信区间：0.80-1.2）报告意外怀孕。与从未意外怀孕的女性（7%）相比，曾有过意外怀孕的女性（29%）报告接受了绝育。在未调整的分析中，非裔美国女性和西班牙裔女性接受绝育的可能性明显更高（比值比：1.5；95%置信区间：1.3-1.9 和比值比：1.4；95%置信区间：1.2-1.7，分别）。在调整了意外怀孕后，这种关系减弱且不再显著（非裔美国女性比值比：1.2；95%置信区间：0.95-1.4，西班牙裔女性比值比：1.3；95%置信区间：1.0-1.6）。
经历意外怀孕的少数民族女性可能会因为之前的意外怀孕经历而选择输卵管结扎。
