    Abstract

    Objective: To determine the effectiveness of an exercise specialist led lifestyle program for adults with type 2 diabetes in primary care. Methods: Eligible participants from 4 primary care networks in Alberta, Canada were assigned to either a lifestyle program or a control group. The program targeted increased daily walking through individualized daily pedometer step goals for the first 3 months and brisk walking speed, along with substitution of low-relative to high-glycemic index foods over the next 3 months. The outcomes were daily steps, diet, and clinical markers, and were compared using random effects models. Results: 198 participants were enrolled (102 in the intervention and 96 in the control). For all participants, (51% were women), mean age 59.5 (SD 8.3) years, A1c 6.8% (SD 1.1), BMI 33.6 kg/m2 (SD 6.5), systolic BP 125.6 mmHg (SD 16.2), glycemic index 51.7 (4.6), daily steps 5879 (SD 3130). Daily steps increased for the intervention compared with the control at 3-months (1292 [SD 2698] vs. 418 [SD 2458] and 6-months (1481 [SD 2631] vs. 336 [SD 2712]; adjusted P = .002). No significant differences were observed for diet or clinical outcomes. Conclusions: A 6-month lifestyle program delivered in primary care by an exercise specialist can be effective for increasing daily walking among adults with recently diagnosed type 2 diabetes. This short-term increase in daily steps requires longer follow-up to estimate the potential impact on health outcomes.
