Abstract

Background: Meta-analyses show that physical activity is an effective management approach for type 2 diabetes that can independently improve glycaemic control. However, primary healthcare professionals report difficulties supporting patients to become more physically active.
Methods: A two-arm, clustered pilot RCT assessed the acceptability, feasibility, and fidelity of a theory-based multifaceted behavioural intervention - Movement as Medicine for Type 2 Diabetes. We estimated mean intervention effects for moderate-vigorous physical activity (MVPA) and HbA1c at 1, 6, and 12-months, and derived the intracluster correlation coefficient (ICC) to inform planning of any subsequent definitive RCT.
Findings: 240 adults (≥18 years; diagnosed with non-insulin dependent type 2 diabetes) were recruited from 11 primary care practices. Participant flowcharts, completion of healthcare professional training, and qualitative feedback indicated that the intervention was acceptable and feasible to healthcare professionals and patients. A 25% patient attrition rate was recorded at 12 months. Fidelity of intervention delivery reduced over time. The effect on daily MVPA (intervention minus control) was 4.7 (95% CI=-3.6 to 13.1) minutes at 1 month, 3.0 (-5.5 to 11.4) minutes at 6 months, and 2.8 (-5.9 to 11.6) minutes at 12 months. The effect on HbA1c was 0.10 at 1 month, (95% CI=-2.0 to 2.2), 0.38 at 6 months (95% CI=-1.7 to 2.5) and 0.87 at 12 months (95% CI=-1.2 to 3.0). The ICC was 0.043 for MVPA and 0.038 for HbA1c.
Discussion: The intervention was acceptable and feasible; however we identified a need for ongoing healthcare professional training/mentoring to increase and maintain patients’ physical activity levels.
