- Abstract
Introduction: It is unknown whether rural‐urban migration contributes to worse the burden of asthma in the cities. Objectives: The aim of this study was to evaluate whether subjects with asthma that migrated from rural areas to a large urban center in Brazil have more severe disease than asthmatic subjects that was born and always lived in the urban area. Methods: This is a case‐control study. We enrolled two groups of subjects with asthma currently living in a large urban center in Brazil: 486 subjects with moderate‐severe asthma and 432 subjects with mild asthma. Results: Rural‐urban migrants had higher odds of moderate‐severe asthma [adjusted OR 1.57, 95% CI (1.18‐2.01)] and uncontrolled symptoms of asthma [adjusted OR 1.80, 95% CI (1.16‐2.76)] than urban‐born subjects. Conclusions: Rural‐urban migrants in Brazil have more severe asthma than urban‐born subjects. Our results suggest that rural‐urban migration is associated with the high burden of asthma in the urban area.
