Association of Acculturation and Health Literacy with Prevalent Dysglycemia and Diabetes Control Among Latinos in the Boston Area Community Health (BACH) Survey

This study assessed the effect of acculturation on type 2 diabetes and whether health literacy may mediate this association. The Boston Area Community Health cohort is a multi-stage stratified random sample of adults from Boston including 744 Latinos. We defined dysglycemia as a HbA1c ≥5.7 %. Multivariable analyses examined the associations between acculturation and health literacy adjusting for demographic and clinical variables. Similar analyses were performed among participants with HbA1c ≥7.0 % to assess the association between acculturation and diabetes control. Among an insured primarily foreign born Spanish speaking Latino population, with a long residence period in the US and good healthcare utilization, higher levels of acculturation were not associated with dysglycemia. Lower levels of acculturation were associated with worse diabetes control. Health literacy level did not modify these associations. Elucidating the components of heterogeneity among Latinos will be essential for understanding the influence of acculturation on diabetes.
