Women, men, and contraceptive sterilization.
OBJECTIVE
To review the social and behavior contexts of decisions about contraceptive sterilization and to analyze factors associated with sterilization choices.


METHODS
Multinomial logit regression of sterilization.


METHODS
Various subsamples as appropriate to specific analyses drawn from the 10,847 women interviewed in the 1995 National Survey of Family Growth, and the 5,227 men interviewed in the National Survey of Families and Households.


METHODS
None.


METHODS
Tubal sterilization and vasectomy.


RESULTS
Surprisingly high proportions of recent tubal sterilizations were performed on unmarried women: 1 in 3 overall, 1 in 5 among white non-Hispanic women, and 2 in 3 among black women. Sterilization choice among continuously married couples also revealed large differences by race and ethnicity. Parity at the time of the last wanted birth is a major factor affecting sterilization choices, although significant effects were found as well as for a number of other variables, including age differences between spouses, education, and religion. Compared with other regions, the ratio of tubal sterilizations to vasectomies is extremely low in the Western region of the United States.


CONCLUSIONS
Analysis of sterilization decisions must be based on time since the completion of childbearing. The findings call attention to the need for measuring variables that mediate observed associations with sterilization outcomes.
