Abstract

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. The trial was registered on ClinicalTrials.gov identifier: NCT00221234.
Footnotes
1
A very small percentage of outliers were found. As an example, at baseline, the percentage of outliers in the Control group, Group 2 and Group 3 for moderate and vigorous PA weekly minutes were 1.1 %, 1.0 % and 2.1 %, respectively.
