Results. Intervention participants showed significantly lower hemoglobin A1c
levels than control participants at both year 1 A = -0.55; P=.021) and year 2
(d=-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.
