To examine the prevalence of sterilization among women aged 20-34 years in rural and urban areas in the United States.
Data were obtained from the 2006-2010 National Survey of Family Growth, a cross-sectional survey conducted by the Centers for Disease Control and Prevention. The study population included the 4,685 female respondents who did not want to become pregnant at the time of the survey. Women who were not sexually active with men or were infertile for reasons other than contraception were excluded. We performed bivariate and stratified analysis and multivariable logistic regression modeling to determine the associations between place of residence and sterilization after considering other demographic characteristics.
Rural women were at increased odds of undergoing sterilization compared with urban and suburban women (22.75% compared with 12.69%, respectively; crude odds ratio [OR] 2.03, 95% confidence interval [CI] 1.44-2.86; risk difference 0.10, 95% CI 0.05-0.16). Education level was found to be a significant effect modifier of the relationship between location of residence and sterilization. In adjusted analysis, controlling for age, parity, race and ethnicity, income, insurance status, history of unintended pregnancy, and relationship status, rural women without a high school degree were more likely to have undergone sterilization compared with urban and rural women with greater than a high school education (OR 8.34, 95% CI 4.45-15.61).
Rural women with low education levels have a high prevalence of sterilization. Future studies need to address the reasons for this interaction between education and geography and its influence on contraceptive method choice.

在美国农村和城市地区，调查 20-34 岁女性的绝育率。
数据来自疾病预防控制中心进行的 2006-2010 年全国家庭增长调查，这是一项横断面调查。研究人群包括 4685 名在调查时不希望怀孕的女性受访者。排除未与男性发生性行为或因避孕以外的原因而不孕的女性。我们进行了双变量和分层分析以及多变量逻辑回归建模，以确定在考虑其他人口统计学特征后，居住地与绝育之间的关联。
与城市和郊区女性相比，农村女性绝育的可能性更高（分别为 22.75%和 12.69%；粗比值比[OR]2.03，95%置信区间[CI]1.44-2.86；风险差异 0.10，95%CI0.05-0.16）。教育水平被发现是居住地与绝育关系的一个显著效应修饰因子。在调整分析中，控制年龄、产次、种族和民族、收入、保险状况、意外怀孕史和关系状况后，未完成高中学业的农村女性与完成高中学业以上的城市和农村女性相比，更有可能接受绝育（OR8.34，95%CI4.45-15.61）。
教育程度低的农村女性绝育率较高。未来的研究需要解决教育和地理位置之间这种相互作用的原因及其对避孕方法选择的影响。
