Does vasectomy explain the difference in tubal sterilization rates between black and white women?

OBJECTIVE To examine whether the observed difference in tubal sterilization rates between black and white women is dependent on racial/ethnic differences in vasectomy rates. DESIGN Secondary analysis of national, cross-sectional survey. SETTING 2002 National Survey of Family Growth. PATIENT(S) Women 15 to 44 years old with a current partner who were able to provide information about their partner's vasectomy status. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The primary outcome was tubal sterilization. Among women with a current partner who had not undergone vasectomy, a multivariable logistic regression model was used to estimate the effects of race/ethnicity on tubal sterilization after adjusting for potential confounders. RESULT(S) Of the 3,391 women in the sample, 14% of white women had a current partner who had undergone vasectomy compared with 5% of Hispanic women and 4% of black women. Among the 3,064 women whose partners had not undergone vasectomy, black women were more likely to undergo tubal sterilization (odds ratio: 1.6; 95% confidence interval: 1.1, 2.2) on the basis of adjusted multivariable analysis. CONCLUSION(S) After controlling for partner vasectomy status, black women were still more likely to undergo tubal sterilization than white women.
