FRIDAY, May 27 (HealthDay News) -- Telephone-delivered cognitive behavioral therapy (CBT) coupled with a walking program may not improve A1c levels in patients with type 2 diabetes and depression, but it appears to improve other important outcomes, according to research published online April 6 in Medical Care.
John D. Piette, Ph.D., of the Ann Arbor VA Healthcare System in Michigan, and colleagues examined hemoglobin A1c levels and blood pressure outcomes in 291 subjects with type 2 diabetes and significant depressive symptoms who participated in a nurse-delivered CBT program that included a pedometer-based walking program.
The researchers found no difference in A1c levels, which were relatively good at baseline. Patients in the intervention group, however, did experience a 4.26 mm Hg decrease in systolic blood pressure relative to controls (P = 0.05), significantly higher increases in step count, and larger reductions in depressive symptoms.
"This program of telephone-delivered CBT combined with a pedometer-based walking program did not improve A1c values, but significantly decreased patients' blood pressure, increased physical activity, and decreased depressive symptoms. The intervention also improved patients' functioning and quality of life," the authors write.
