Nicaraguan migration and the prevalence of adolescent childbearing in Costa Rica.

This study describes the dynamics of adolescent childbearing of Nicaraguan-born and Costa Rican-born adolescents in Costa Rica and examines the association between socio-demographic factors and adolescent childbearing in the country. We studied Nicaraguan-born and Costa Rican adolescents using the data of the 2000 Census. Multivariate logistic regression was used to analyze the association between country of origin and adolescent childbearing, while controlling for socio-demographic factors (age, education, union, urbanization and poverty). 26% of Nicaraguan-born migrants and 9.5% of Costa Ricans had given birth during adolescence. The migrants' increased odds of pregnancy decreased from 3.34 (CI 3.21, 3.48) to 1.88 (CI 1.79, 1.97) when controlling for socio-demographic factors. Age, low educational attainment, urban residence, poverty and union were all significant predictors of adolescent pregnancy. Nicaraguan-born status is associated with adolescent childbearing in Costa Rica. Further research is needed to understand what factors, other than socio-demographic indicators, contribute to the differing prevalence of adolescent childbearing in Costa Rica.
