A cross-sectional population-based and a subsequently a nested case-control study was conducted in 2008 using the protocol of the International Study of Asthma and Allergies in Childhood (ISAAC). Risk factor analysis used the chi-square test, Fisher's exact test, and binary logistic regression. Variables with p < 0.20 in the bivariate analysis entered the logistic regression model, with six variables remaining in the final model (p < 0.05). Prevalence of active asthma was 19.1%. Risk factors for active asthma (p = 0.01) were: smoking during pregnancy, exclusive breastfeeding < 6 months, family income < 3 minimum wages, female gender, pets currently in the home, and absence of fish in the diet.
