Feeding Regulation in SCI
Study Details
Study Description
Brief Summary
The overall purpose of this research is to understand the reasons why persons with spinal cord injuries eat more calories than they need to "burn", stay alive, and function. This research will investigate how quickly food moves through a participant's body, the hormones in the participant's body that control energy and digestion, and a participant's impressions of hunger after eating a meal. This will be compared in persons with and without a spinal cord injury.

Experimental: Spinal Cord Injury Group Participants who have a spinal cord injury will receive two meals on two separate visits between five to seven days. |
Other: Test Meals
For the first meal, Participants will be fasted for 8 hours and will consume a test meal of 255 calories (120 g egg substitute [60 kcal]; 2 slices of bread [120 kcal] with 30 g strawberry jam [75 kcal]; 72% carbohydrate, 24% protein, 2% fat, and 2% fiber) with 120 mL of water.
After five to seven days, participants will be fasted for 10 hours and will consume a second test meal of 510 calories (240 g egg substitute [120 kcal]; 4 slices of bread [240 kcal] with 60 g strawberry jam [150 kcal]; 72% carbohydrate, 24% protein, 2% fat, and 2% fiber) with 240 mL of water.

Outcome Measures
Primary Outcome Measures
- Gastric emptying time [Up to seven days]
Gastric emptying will be measured by the SmartPill Wireless Motility Capsule
- Upper gastrointestinal transit time [Up to seven days]
Upper gastrointestinal transit time will be measured by the SmartPill Wireless Motility Capsule
Secondary Outcome Measures
- Change in postprandial ghrelin [Before the second test meal (up to 7 days) and up to 120 minutes after the second test meal (up to 7 days).]
Measured by serum blood samples
- Change in postprandial peptide tyrosine tyrosine (PYY) [Before the second test meal (up to 7 days) and up to 120 minutes after the second test meal (up to 7 days).]
Measured by serum blood samples
- Change in postprandial cholecystokinin (CKK) [Before the second test meal (up to 7 days) and up to 120 minutes after the second test meal (up to 7 days).]
Measured by serum blood samples
- Change in postprandial Glucagon Peptide 1 (GLP-1) [Before the second test meal (up to 7 days) and up to 120 minutes after the second test meal (up to 7 days).]
Measured by serum blood samples
- Change in subjective appetite rating as measured by Palatability Series Visual Analogue Scale [Baseline and up to 7 days]
Change in subjective appetite rating will be measured by Palatability Series Visual Analogue Scale that ranges from 0 mm as "not pleasant" to 100 mm as "extremely pleasant"
- Change in subjective appetite rating as measured by Hunger Series Visual Analogue Scale [Baseline and up to 7 days]
Change in subjective appetite rating will be measured by Hunger Series Visual Analogue Scale that ranges from 0 mm as "not at all hungry" to 100 mm as "totally/a lot/very hungry".
- Total percentage body fat [Baseline]
Measured by Dual x-ray absorptiometry (DXA)
