Improving Dietary Protein Intake in Adults
May 4, 2020 updated by: Florida Atlantic University
A pilot, single-arm investigation used coaching, nutrition education, and a per-meal protein prescription to assess impact on protein intake, muscle strength and function in older adults.
Study Overview
Detailed Description
Objective: To evaluate the effects of nutrition education, diet coaching, and a protein prescription (PP) on protein intake, and associations with muscle strength and function.
Design: Prospective pretest posttest single-arm study.
Setting: Urban area, East coast of South Florida.
Participants: Older adults.
Intervention: 10-week telephone-based diet coaching, nutrition education and a per-meal PP.
Measurements: Protein and energy intakes, weight, grip strength (GS), and 5-chair-rise (5CR), timed up and go (TUG), 3-meter walk (3mW) tests at baseline and 10 weeks.

Measure Description |
Time Frame |
---|---|---|
Change in Protein intake

|
Protein intake (g/kg/body weight) per day
|
Change from baseline to 10 weeks

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Grip strength
Time Frame: Change from baseline to 10 weeks
|
Grip strength measured using dynamometer
|
Change from baseline to 10 weeks
|
Change in Timed Up and Go Test
Time Frame: Change from baseline to 10 weeks
|
The timed up and go test measures the time (in seconds) that it takes to stand up from a seated position in a chair, walk 3 meters away from the chair at a comfortable pace to a line on the floor, turn around, walk back, and sit back down in the chair.
|
Change from baseline to 10 weeks
|
Change in 3 meter walk
Time Frame: Change from baseline to 10 weeks
|
The 3-meter walk test measures the time (in seconds) that it takes to stand up from a seated position in a chair and walk 3 meters away from the chair at a comfortable pace to a line on the floor
|
Change from baseline to 10 weeks
|
Change in 5-Chair Rise Stand Test
Time Frame: Change from baseline to 10 weeks
|
The 5 chair rise stand test requires participants to stand up 5 times without hand assistance from a straight back chair without an armrest.
The time required to complete the 5 chair rises is recorded.
|
Change from baseline to 10 weeks
|
Change in Short Performance Physical Battery Score
Time Frame: Change from baseline to 10 weeks
|
The Short Physical Performance Battery (SPPB) consists of timed measures of balance, 3-meter walk, and 5-chair rises.
The balance portion requires participants to stand with feet next to each other, the toes of one foot next to the heel of the other foot, and heel to toe for a 10 second duration.
Scores are assigned based on the number of seconds the participant can stand in the position for balance.
Scores for the chair rise and 3 meter walk are based on the time taken to complete the task.
The scores are totaled to arrive at the Short Performance Physical Battery Score
