Adolescent fertility and religion in Rio de Janeiro, Brazil in the year 2000: the role of Protestantism.

Social transformations in Brazil in recent years have included a substantial increase in adolescent fertility, a dramatic rise in membership of Protestant religious denominations, and an accompanying decline in the number of Catholics. We used the 2000 Brazil Census to examine differentials in fertility and family formation among adolescents living in Rio de Janeiro by the following religious denominations: Catholic; Baptist; other mainline Protestant; Assembly of God Church; Universal Church of the Kingdom of God; other Pentecostal Protestant; and no religion. Results from logistic regression models show that the majority of the Protestants are at a lower risk of adolescent fertility than Catholics, and that among adolescents who have had a child, most Protestants are more likely than Catholics to be in a committed union. Our findings offer some support for the hypothesis that Protestant churches are more effective than the Catholic Church in discouraging premarital sexual relations and childbearing among adolescents.
