Undernutrition
Conditions
Brief summary
The purpose of this study was to determine the improvement in nutritional status, especially in the level of insulin-like growth factor-1 (IGF-1) and its relationship with changes in the circulating cytokine levels, after providing extra protein and energy contents to community-dwelling older adults at risk of undernutrition.
Detailed description
Sixty of aged over 65 years, living independently in the community for elderly people, nondiabetic subjects with serum prealbumin of under 30 mg/dL and BMI under 25 kg/m2 were recruited. The subjects were followed for a 2-week pre-intervention period, followed by an intervention period, which they received 2 cartons of liquid oral nutritional supplementation daily for 2 weeks.
Interventions
First 2-weeks : keeping routine dietary habit
Pre-intervention period was followed by an intervention period, during which consumed twice-daily 200 mL cartons of oral liquid nutritional supplementation (total 400 mL daily, containing 16 g protein, 12 g fat and 60 g carbohydrate and providing 400 kcal)
