Background: Physical activity (PA) is associated with reduced morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM); however, most T2DM adults are insufficiently active. Purpose: To explore the effectiveness of two innovative/theoretically based behavioral-change strategies to increase PA and reduce hemoglobin A1c (A1c) in T2DM adults. Methods: Participants (n=287) were randomly assigned to a control group or an intervention group (i.e., print-based materials/pedometer group or print-based materials/pedometer plus telephone-counseling group). Changes in PA and A1c and other clinical measures were examined by Linear Mixed Model analyses over 18 months, along with moderating effects for gender and age. Results: PA and A1c levels did not significantly change in intervention groups. Step counts significantly increased in the print-based materials and pedometer plus telephone counseling group, for women. Conclusions: No significant effects were found for PA or A1c levels for T2DM adults. The multi-component strategy including telephone counseling may have potential for women.
