Item Socio-Demographic Factors and Intergenesic Interval in Nicaraguan Immigrant Mothers in Costa Rica(Población y Salud en Mesoamérica; Volumen 5, Número 2, 2008) Bonilla Carrión, Róger Enrique; Cardoza, DavidAdequate birth intervals are considered a positive factor in the health of mothers and their children. One of the objectives of this study is to compare the birth interval between Nicaraguan immigrant women and local mothers in Costa Rica. Birth intervals among Nicaraguan women are significantly shorter than the local ones (p < 0.001). Half of the children of the Nicaraguan mothers have birth intervals of a minimum of 335 days (less than one year). Half of the local children have birth intervals of a minimum of 881 days (2.4 years). A second objective in this study is to fit a Cox's proportional stratified hazard model of the type in order to λs(t,X) = λo(t)exp(βis,'Xi) model the birth interval as a time-to-event variable (pregnancy of the next child). Fitting by nationality of the mother, age, and age on first birth-delivery, the hazard ratios are respectively 1.3 (p < 0.001), 0.93 (p < 0.001), and 1.02 (p > 0.05). Nicaraguan women are 30% more likely to recur in the following pregnancy as compared with local women. The study of population minorities permits the preparation of public policies on international migration issues.Item Nicaraguan migration and the prevalence of adolescent childbearing in Costa Rica(Journal of Immigrant and Minority Health, vol.15(1), 2012) Sintonen, Heidi; Bonilla Carrión, Róger EnriqueThis 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.
