Female sterilization in Latin America: cross-national perspectives

Fertility levels have dropped substantially in Latin America in recent decades, fuelled by increased contraceptive use and notably a method mix skewed towards female sterilization. This study examined choice of female sterilization in four Latin American countries: Brazil, Colombia, the Dominican Republic and Peru. Data were drawn from national Demographic and Health Surveys conducted in 1995--1996. Discrete-time hazard models were used on the five-year calendar modules of women's reproductive histories to consider the effects of a number of sociodemographic and contextual determinants as they pertained to status at the moment of the event. The results revealed that the likelihood of a woman's having undergone contraceptive sterilization was increasing over time in Brazil and Peru, suggesting that the potential for future growth of this method remains strong. A consistent pattern of increased probability of sterilization with higher education was seen across all countries, seemingly dispelling certain controversial claims that the procedure may have been disproportionately performed on the poor. At the same time, the multilevel analytical approach pointed to significant cluster-level random effects, suggesting that there were additional unmeasured contextual influences on women's propensity to choose sterilization.
