Migration among individuals with leprosy: a population-based study in Central Brazil.

This study investigates social and clinical factors associated with migration among individuals affected by leprosy. A cross-sectional study was conducted among those newly diagnosed with leprosy (2006-2008), in 79 endemic municipalities in the state of Tocantins, Brazil (N = 1,074). In total, 76.2% were born in a municipality different from their current residence. In the five years before diagnosis 16.7% migrated, and 3.6% migrated after leprosy diagnosis. Findings reflect aspects associated with historical rural-urban population movement in Brazil. Indicators of poverty were prominent among before-diagnosis migrants but not after-diagnosis migrants. Migration after diagnosis was associated with prior migration. The association of multibacillary leprosy with migration indicates healthcare access may be an obstacle to early diagnosis among before-diagnosis migrants, which may also be related to the high mobility of this group.

Resumo Este estudo investiga fatores sociais e clínicos associados à migração entre pessoas afetadas pela hanseníase. Estudo transversal entre recémdiagnosticados com hanseníase (2006-2008), em 79 municípios endêmicos do Estado de Tocantins, Brasil (N = 1.074). No total, 76,2% nasceram em município diferente de sua residência atual. Nos cinco anos antes do diagnóstico, 16,7% migraram, e 3,6% migraram após o diagnóstico da hanseníase. Resultados refletem aspectos associados com o movimento histórico da população rural-urbana no Brasil. Indicadores de pobreza foram proeminentes antes do diagnóstico de migrantes. A migração após o diagnóstico foi associada com migração anterior. A associação da forma multibacilar com migração indica que o acesso à saúde pode ser um obstáculo para o diagnóstico precoce de migrantes, o que pode também estar relacionado com a elevada mobilidade desse grupo.
