摘要

Aim

The study evaluated the association between internal migration patterns and multimorbidity in 13,146 adults in the ELSA-Brasil study.

Subject and methods

Participants diagnosed with two or more health conditions out of 15 were classified with multimorbidity. A migrant was defined as an individual whose residence at the beginning of schooling was different from the municipality of residence at the baseline. Migration was categorized as nonmigrant, downward migrant (moved to a lower-ranked destination), or upward migrant.

Results

Of the participants, 45.3% were migrants, and 69.6% had multimorbidity. 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.

Conclusion

The results from the ELSA-Brasil study indicated a relationship between internal migration and the prevalence of multimorbidity in adults, where the upward trajectory was protective for both sexes and the downward trajectory showed a risk for women.
