ACTIVNES: Oral medical nutrition + exercise = benefit
Functional status and quality of life are important outcomes especially as we age. From international guidelines ESPEN (European Society for Clinical Nutrition and Metabolism) there is a grade A recommendation to use oral medical nutrition to improve or maintain nutritional status in frail older adults. There is also recognition of the positive benefits of exercise in the aging population.
PUBLICATION SUMMARY
Effects of an Oral Nutritional Supplementation Plus Physical Exercise Intervention on the Physical Function, Nutritional Status, and Quality of Life in Frail Institutionalized Older Adults: The ACTIVNES Study
Abizanda P, López MD, García VP, Estrella Jde D, da Silva González Á, Vilardell NB, Torres KA* J Am Med Dir Assoc. 2015 May 1;16(5):439.e9-439.e16
Objective
To assess the effects of a high protein high calorie ONS with prebiotic fiber, vitamin D, and calcium (Resource® Senior Activ), plus a standardized physical intervention, in the functional status, strength, nutritional status, and quality of life of frail institutionalized older adults.
Materials and Methods
Population
- 4 nursing homes in Spain : 91 elderly residents
- ≥ 70 years
- Able to walk 50m
- Sarcopenic (or at risk: ≥ 3 Fried failty test)
Intervention
- Nutrition: 2x 200ml Resource® Senior Activ
- Physical exercise: 5x week (balance, flexibility, strength)
Measurements
| Functional Status | Quality of Life | Nutritional Status |

Results
- 76% completed the 12 week intervention (n=69)
- Adherence to ONS: 62.6% of participants consumed >80%
- Adherence to exercise: 93.4% of participants exercised >80%
Function Status
- Mean values significant after 6 weeks but not 12 weeks
Quality of Life
- EQ-5D VAS – 6 weeks: 60–66 (6; 3–10)†
- EQ-5D VAS – 12 weeks: 59–64 (5; 0–10)∗
Nutrition Status
- Weight 59.9–61.6 (1.7; 0.9–2.5) ‡
- BMI: 26.5–27.3 (0.8; 0.4–1.2)‡
- MNA: 10.3–11.1 (0.8; 0.1–1.5)∗
- Speed D: 17.4–25.3 (7.9; 5.0–10.8)‡
∗ P < .05 ; † P < .01 ; ‡ P < .001. Participants had greater probability of improving functional status when they presented with lower baseline scores, lower baseline BMI, lower vitamin D levels, and more baseline frailty criteria.
Conclusion
- A specific ONS supplementation (high protein, high calorie, extra vit D and calcium) plus physical exercise in frail institutionalized older adults, improved functional status at 6 weeks, nutritional status at weeks 6 and 12, and quality of life at weeks 6 and 12.
- Elderly residents with a lower BMI, lower previous physical function, higher number of frailty criteria, and lower vitamin D levels had an independent association with functional improvement.
