It is unknown whether rural-urban migration contributes to worse the burden of asthma in the cities.
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.
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.
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.
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.
城乡迁移是否会加重城市哮喘负担尚不清楚。
本研究旨在评估从农村地区迁移至巴西一个大型城市中心的哮喘患者是否比出生并一直生活在城市地区的哮喘患者病情更严重。
这是一项病例对照研究。我们招募了两组目前居住在巴西一个大型城市中心的哮喘患者：486名中重度哮喘患者和432名轻度哮喘患者。
与城市出生的患者相比，城乡移民患中重度哮喘的几率更高[调整后的比值比为1.57，95%置信区间(1.18 - 2.01)]，哮喘症状控制不佳的几率也更高[调整后的比值比为1.80，95%置信区间(1.16 - 2.76)]。
巴西的城乡移民比城市出生的患者哮喘病情更严重。我们的研究结果表明，城乡迁移与城市地区哮喘的高负担有关。
