Abstract

Background: Differences in asthma prevalence between urban and rural areas have been observed worldwide. Epidemiological studies in middle- and low-income countries suggest that internal migration processes may partly explain these disparities.

Objective: To investigate the association between internal migration and asthma in children living in transitional areas of Ecuador.

Methods: A cross-sectional study was conducted using data from a birth cohort of children living in a tropical coastal region in northwestern Ecuador. Asthma indicators included wheezing in the past 12 months, ever wheezing, and asthma diagnosis by a doctor. Internal migration was defined as a change of residence between geographical units: cantonal, parish, and census tract. The relationship between asthma and migration was analyzed using binary logistic regression.

Results: Of 2,404 participants, 1,818 children met the inclusion criteria. Among them, 2.8% experienced cantonal migration, 11.9% parish migration, and 24.6% census tract migration. The prevalence of wheezing in the past 12 months, ever wheezing, and asthma diagnosis by a doctor was 13.1%, 33.3%, and 7%, respectively. Children with a history of cantonal migration were more likely to have experienced wheezing compared to those who did not migrate (OR: 1.56; 95%CI: 0.87-2.79).

Conclusions: Changes in residence between smaller or adjacent geographic units appeared not to be associated with asthma prevalence. However, cantonal migration may play a role in respiratory health outcomes.

厄瓜多尔国内移民及其与儿童哮喘的关系：一项横断面研究。

背景：在世界范围内已经观察到城乡哮喘患病率的差异。中低收入国家的流行病学研究表明，国内移徙过程可能部分解释了这些差异。目的：探讨厄瓜多尔过渡地区儿童内部迁移与哮喘的关系。方法：横断面研究使用数据从出生队列的儿童生活在厄瓜多尔西北部的热带沿海地区。哮喘指标包括过去12个月的喘息、曾经喘息和医生诊断的哮喘。内部迁移被定义为地理单位之间的居住变化：州、教区和人口普查区。采用二元logistic回归分析哮喘与迁移的关系。结果：2404名参与者中，1818名儿童符合纳入标准。其中，州迁移占2.8%，教区迁移占11.9%，人口普查区迁移占24.6%。过去12个月的喘息、曾经喘息和被医生诊断为哮喘的患病率分别为13.1%、33.3%和7%。与没有迁移的儿童相比，有州迁移史的儿童更有可能经历喘息(OR: 1.56；95%置信区间:0.87—-2.79)。结论：较小或相邻地理单元之间的居住地变化似乎与哮喘患病率无关。然而，州际迁移可能在呼吸健康结果中发挥作用。
