Some research provided robust analyses of the affected population s ’ health inequities and demonstrated how a task shifting intervention redressed those concerns .
Introduction Task shifting interventions have been implemented to improve health and address health inequities .
Little is known about how inequity and vulnerability are defined and measured in research on task shifting .
We conducted a systematic review to identify how inequity and vulnerability are identified , defined and measured in  task shifting research from high-income countries .
Mexican American trial of community health workers: a randomized controlled trial of a community health worker intervention for Mexican Americans with type 2 diabetes mellitus.
OBJECTIVES We assessed whether community health workers ( CHWs ) could improve glycemic control among Mexican Americans with diabetes . METHODS We recruited 144 Mexican Americans with type 2 diabetes between January 2006 and September 2008 into the single-blinded , r and omized controlled Mexican American Trial of Community Health Workers ( MATCH ) and followed them for 2 years . Participants were assigned to either a CHW intervention , delivering self-management training through 36 home visits over 2 years , or a bilingual control newsletter delivering the same information on the same schedule . RESULTS Intervention participants showed significantly lower hemoglobin A1c levels than control participants at both year 1 Δ = -0.55 ; P = .021 ) and year 2 ( Δ = -0.69 ; P = .005 ) . We observed no effect on blood pressure control , glucose self-monitoring , or adherence to medications or diet . Intervention participants increased physical activity from a mean of 1.63 days per week at baseline to 2.64 days per week after 2 years . CONCLUSIONS A self-management intervention delivered by CHWs result ed in sustained improvements in glycemic control over 2 years among Mexican Americans with diabetes . MATCH adds to the growing body of evidence supporting the use of CHWs to reduce diabetes-related health disparities
