Brazil has experienced an increase in the number of individuals living with multimorbidity. Migratory movements influence the occurrence of diseases among migrants and non-migrants, however, this relationship is scarcely investigated.

Objetivos

The study aimed to evaluate the association between patterns of internal migration in early life and the prevalence of multimorbidity in adults in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Metodologia

Baseline data from the ELSA-Brasil were analyzed, with a final sample size of 13.146 employees of both sexes. Participants diagnosed with ≥ 2 conditions from a list of 15 were classified with multimorbidity. A migrant was defined as an individual whose municipality of residence at the beginning of schooling was different from the municipality of residence at the study baseline. Migration was categorized as nonmigrant, downward migrant, or upward migrant. We performed a logistic regression analysis for men and women to test the association of early migration with multimorbidity adjusting for age and maternal education.

Resultados

Of the total participants, 45.3% were migrants, and 69.6% had multimorbidity. After adjustments for confounding factors, we found a significant association between upward migration and multimorbidity in men (OR [95% CI], 0.88 [0.78 - 0.99]. For women, associations were found between upward (OR [95% CI], 0.84 [0.75 - 0.94] and downward migration (OR [95% CI], 1.43 [1.16 - 1.77] and the outcome.

Conclusões/Considerações

The results indicated a relationship between early internal migration trajectory and the prevalence of multimorbidity in adults from the ELSA-Brasil study.
