Brief Summary:
The purpose of this study is to determine whether protein-energy nutritional supplementation improves geriatric function in community-dwelling frail older adults of low socioeconomic status.

Condition or disease Intervention/treatment Phase
Frail Dietary Supplement: Nutritional Supplementation Other: Control Not Applicable

Detailed Description:

Chronic undernutrition is a common condition in older people, and is clearly an important component of frailty. However, the effect of protein-energy nutritional supplementation on the functional status of frail older people is controversial. Some investigators suggested that, if nutritional or functional status has deteriorated too far, it could be very difficult for single nutritional supplementation to reverse malnutrition progression or functional decline.

The investigators believe one of the reasons for these ineffective results, especially for the community-dwelling frail elderly, may be due to a lack of regard to the socioeconomic status of the study population. For this reason, the investigators recruited a study sample with low socioeconomic status and evaluated the effect of protein-energy nutritional supplementation on their disability scores and physical performance.

Arm Intervention/treatment
Experimental: Supplementary Group Dietary Supplement: Nutritional Supplementation
- Providing two 200mL per day of commercial liquid formula cans for 12 weeks (additional 400kal of energy, 25g of protein, 9.4g of essential amino acids (60.2% leucine), 400mL of water, and micronutrients per day)
Other Name: Greenbia HP (Dr. Jung's Food Co., Ltd., Korea)
No Intervention: Control Group Other: Control
- No intervention, except monthly home visits

Primary Outcome Measures :
  1. Functional Status [ Time Frame: 12 weeks ]
