Real-world impact of ongoing regular exercise in overweight and obese US adults with diabetes on health care utilization and expenses.

Aims: To assess the effect of regular exercise on health care utilization patterns and expenses in a real-world national sample of overweight and obese US adults with diabetes.

Methods: Medical Expenditure Panel Survey data (2010-2015) identified adults with diabetes and a body mass index (kg/m) ≥25. Two groups were created: exercise (moderate or vigorous physical activity >30min at least five times weekly) and non-exercise groups.

Outcomes Measured: average total health care expenses (per-person per-annum) and the likelihood of hospitalization.

Results: Among 5140 overweight and obese adults with diabetes, 49.1% reported exercising at least five times weekly. The exercise group showed lower medical care and prescription drug utilization than the non-exercise group (p<0.001). Total unadjusted health expenses in the exercise group were $5651 lower than the non-exercise group (p<0.001). After controlling for socioeconomic and health-related variables, regular exercise reduced total health care expenses by 22.1% (p<0.001) and the likelihood of hospitalization by 28% (p=0.001).

Conclusions: Reduced hospitalization and health care expenses were associated with regular exercise (≥30min at least five times weekly) in overweight and obese adults with diabetes.
