Yoshizawa Y, Kim J, Kuno S. Effects of a Lifestyle-Based Physical Activity Intervention on Medical Expenditure in Japanese Adults: A Community-Based Retrospective Study. Biomed Res Int. 2016;20167530105.
BACKGROUND
This study aimed to investigate whether a lifestyle-based physical activity program could contribute to reduced medical expenditure.

METHODS
The study participants were 60 adults aged 63. 1 (standard deviation, 4. 4) years in the intervention group; the case-control group consisted of 300 adults who were randomly selected from Japan's national health insurance system. This community-based retrospective study incorporated a 3-year follow-up.

RESULTS
The total and outpatient medical expenditure in the intervention group were significantly lower than in the control group: total expenditure, $US640. 4/year; outpatient expenditure, $369. 1/year. The odds ratio for outpatient visiting was 6. 47-fold higher in the control than in the intervention group.

CONCLUSION
Our study suggests that a health program to promote physical activity can result in reduced total medical expenditure, outpatient medical expenditure, and possibly also inpatient medical expenditure.
