Community health worker interventions for Latinos with type 2 diabetes: A systematic review of randomized controlled trials
Little TV, Wang ML, Castro EM, Jiménez J, Rosal MC

Abstract
This systematic review aimed to synthesize glucose (HbA1c) outcomes of community health worker (CHW)-delivered interventions for Latinos with type 2 diabetes that were tested in randomized controlled trials and to summarize characteristics of the targeted populations and interventions, including the background, training, and supervision of the CHWs. Searches of PubMed and Google Scholar databases and references from selected articles identified 12 studies that met the inclusion criteria. Of these, seven reported statistically significant improvements in HbA1c. Study participants were largely low-income, female, and Spanish-speaking and had uncontrolled diabetes. The CHWs led the interventions alone, in pairs, or as part of a team. Interventions varied considerably in session time, duration, and number. Most met standards for tailored, high-intensity interventions and half were theory-based. Overall, methodological quality was good but there were inconsistencies in the reporting of key information. Future research should report in greater detail CHW background, training, and supervision; examine factors associated with intervention effectiveness; and provide data on cost and cost-effectiveness.
