Glycemic control among Latinos with type 2 diabetes: The role of social-environmental support resources.

OBJECTIVE: Although active diabetes self-management is required to achieve glycemic control, adherence is poor among ethnic minorities, especially Latinos. Research shows that individuals who report greater social-environmental support resources for disease management manage their diabetes more effectively than those with fewer support resources. METHODS: Path analysis was conducted to investigate the value of a multiple-mediator model in explaining how support resources for disease management influence hemoglobin A1c (HbA1c) levels in a sample of 208 Latinos with Type 2 diabetes recruited from low-income serving community clinics in San Diego County. We hypothesized that the relationship between support resources for disease-management and HbA1c would be mediated by diabetes self-management and/or depression. RESULTS: Participants who perceived greater support resources for disease-management reported better diabetes self-management (β = .40, p < .001) and less depression (β = -.19, p < .01). In turn, better diabetes self-management and less depression were associated with tighter glycemic control (HbA1c; β = -.17, p < .05 and β = .15, p < .05, respectively). Once the indirect effects via diabetes self-management (95% CI [-.25; -.03]) and depression (95% CI [-.14; -.01]) were statistically controlled, the direct pathway from support resources to HbA1c was markedly reduced (p = .57). CONCLUSIONS: These findings demonstrate the important connection that support resources for disease management can have with diabetes self-management, emotional well-being, and glycemic control among Latinos. Thus, programs targeting diabetes self-management and glycemic control in this population should consider culturally relevant, multilevel influences on health outcomes.
