Physical activity (PA) is a cornerstone of treatment for type 2 diabetes mellitus (T2D). Among other benefits, regular PA improves physical function which can prevent institutionalization. However, effective PA interventions are not widely adopted in primary care. Our recent systematic review identified an effective PA intervention for adults with T2D that was nearly pragmatic enough for use in primary care. However, it still required adaptation to fit clinic work flows and to be reimbursed by insurance. After adapting the intervention (Be ACTIVE) to address these issues, we hypothesized Be ACTIVE would improve PA and physical function relative to randomized controls. This pragmatic pilot trial randomized adults with T2D to 12 weeks of Be ACTIVE (6 telephone behavioral counseling sessions + PA tracking (FitBit©); 3 primary care visits to teach strength exercises + monitor safety) vs. enhanced usual care (3 self-management mailings). At baseline and post-intervention, we assessed PA with Actigraph© accelerometers (steps/week) and physical function by a timed 400-meter walk (sec) and the Short Physical Performance Battery (SPPB, 0-12 scale). To date, we have completed assessments for 15 participants (n=8 Be ACTIVE, n=7 controls). Pre-post PA increased by 19.8% in the Be ACTIVE group (+5122 ± 10steps/week; data shown as mean ± SE) and decreased by 15.9% in controls (-3122 ± 1233 steps/week). SPPB scores increased by a clinically important >1-point difference in the Be ACTIVE group (+1.1 ± 0.2), and were stable in controls (+0.3 ± 0.1). The 400-meter walk time improved by 10.3% in Be ACTIVE participants (-38.3 ± 6.6 sec) and declined by 5.4% in controls (+17.3 ± 6.4 sec). Be ACTIVE is a reimbursable intervention delivered by primary care staff. Strong pilot data support that Be ACTIVE improves PA/physical function. If our data remain promising at trial completion, the next step towards broader dissemination will be to test Be ACTIVE in multiple clinical settings.
