Nutritional Supplementation in the Elderly With Weight Loss

Overview

Many elderly experience weight loss and weakness with normal aging. Although there is extensive literature regarding nutritional advice for the elderly, there are few well- designed studies evaluating the effect of oral nutrition supplements in patients with weight loss and aging. The aim of this study is to examine the effect of dietary prescription with or without nutrition supplementation that includes soy protein, whey protein and fish oil in elderly patients who have suffered unintentional weight loss.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Other
    • Masking: None (Open Label)
  • Study Primary Completion Date: September 15, 2020

Detailed Description

This is an 8-week, randomized, pilot study with elderly subjects (age 65 and older) with recent unintentional weight loss who will receive either two servings of supplement powder and fish oil or no dietary supplementation (N=10 for each group).

Interventions

  • Dietary Supplement: Protein shake + Fish Oil
    • 2 shakes of protein as well as 1 fish oil daily.

Arms, Groups and Cohorts

  • Experimental: Supplement + Fish Oil
    • Participants will mix 5 scoops of powdered nutrition supplement with 8 oz of cold water (2x/day). The supplemental shake will be consumed on two separate occasions daily. Omega-3 fish oil supplement is in capsule form for intake once daily. The NutraWell nutrition powder and OmegaRich fish oil supplement will be provided by and distributed from DoWell Laboratories (Irvine, CA – USA).
  • No Intervention: Control
    • No dietary supplements. Participants will continue current intake.

Clinical Trial Outcome Measures

Primary Measures

  • Body Composition
    • Time Frame: 8 weeks
    • To assess if body composition is altered with increased protein supplementation using bioelectrical impedance body composition analysis to provide weight in pounds.
  • Nutritional Status
    • Time Frame: 8 weeks
    • To assess if increased protein supplementation and fish oil has impact on nutrition status using Mini Nutritional Assessment questionnaire (minimum value 0, maximum value 14), where higher scores correlate to better nutritional status and lower scores indicate malnutrition.
  • Functional Improvements
    • Time Frame: 8 weeks
    • To determine if protein supplementation improves functional movement using hand grip strength test as well as 6-minute walk test.
