ABSTRACT
OBJECTIVE: We examined asthma risk factors among 274 Puerto Rican children born in New York to atopic mothers. METHODS: We prospectively followed the cohort to measure aeroallergens in their homes and assess allergic sensitization. Baseline data are presented. RESULTS: Maternal smoking was significantly higher among women born on the continental United States (25%) vs. those born elsewhere (11%). Cat ownership was more frequent among mainland-born women (15%) compared with those born in Puerto Rico (4%). While some aeroallergens were prevalent, few dust samples contained detectable dust mite allergens. CONCLUSIONS: By following this cohort, we hope to identify the roles that socio-cultural factors play in the process of allergic sensitization.
