The Mexican American Trial of Community
Health Workers (MATCH) sought to address
these limitations of the literature through a
rigorously designed behavioral randomized
controlled trial with outcomes measured at
1 and 2 years. The primary study hypothesis
was that the CHW intervention, compared with
an attention control, would result in improvement
in short-term physiological outcomes
(mean HbAlc levels and percentage with
controlled blood pressure). A secondary hypothesis
was that the CHW intervention
would improve adherence to self-management
behaviors, such as daily self-monitoring
of blood glucose, medication taking, and adherence to diet and physical activity
recommendations.
