OBJECTIVES: The purpose of this study was to examine intervention effects of a community-based prevention program for pre-frail elderly individuals by comparing an intervention group (exercise with nutritional care) with a control group (exercise without nutritional care). METHODS: The study was conducted in Y town and S city in Ibaraki Prefecture in Japan. The subjects comprised 161 pre-frail elderly individuals in the community-based prevention program, who were divided into two groups, the intervention group (N = 81, Y town, mean age : 76.2 +/- 5.7 years), and the control group (N = 81, S city, mean age 76.2 +/- 4.7 years). The items surveyed included age, gender, activities of daily living, functional capacity, and dietary variety score (DVS). Functional fitness measurement items (grip strength, alternate step, 5-repetition sit-to-stand, one-leg balance with eyes open, tandem stance, functional reach (FR), sit and reach, 5-m habitual walk, and timed up and go (TUG)) and blood data were assessed at the beginning and end of the intervention. RESULTS: The DVS of the intervention group was significantly improved compared to that of the control group (P < 0.01). In particular, the food frequencies of fish and shellfish, meat, eggs, milk, fruits, and fat and oil (P < 0.01) were significantly increased in the intervention group, as were those of soybean products, seaweed, and potatoes (P < 0.05). On the other hand, significant increases were seen only in the frequencies of fish and shellfish, meat, and milk in the control group. The intervention group showed significant improvement in five-repetition sit-to-stand, tandem stance, FR, sit and reach, and TUG by the end of the intervention. In addition, the intervention group's performance on one-leg balance with eyes open (P < 0.05) was significantly improved even after adjusting for age, gender, and the functional fitness measurement items which were different at the beginning of the study. CONCLUSION: This study suggests that a combined exercise and nutrition program for pre-frail elderly individuals improves their food intake and functional fitness.
