Oral Processing and Appetite in Older Adults
January 2, 2023 updated by: Miriam Clegg, University of Reading
The Effect of Dentition, Eating Rate, Oral Processing, and Gastric Emptying on Appetite and Satiety in Older Adults (≥65 Years of Age)
The goal of this observational study is to learn about changes in oral processing and appetite in older adults aged 65+ years old.
The main question it aims to answer is if oral processing affects gastric emptying in older adults (≥65 years old).

Detailed Description
- To investigate if food intake and satiety differ between faster and slower eaters, within older adults (≥65 years old).
- To assess if chewing rate, salivary flow rate, oral processing and gastric emptying differ between older adults (≥65 years old) with smaller versus bigger appetites.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Objective appetite assessment: Ad-libitum meal consumption
Time Frame: 20 minutes
|
Consumption of the ad-libitum meal is measured (g).
Participants are instructed to eat until they feel comfortable full
|
20 minutes
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Subjective appetite assessment: VAS
Time Frame: Every 30 minutes for 3 hours
|
Appetite are assessed using a 100 mm Visual Analogue Scales (VAS, scale 0-100)
|
Every 30 minutes for 3 hours
|
Gastric Emptying
Time Frame: Samples taken every 15 minutes for 3 hours
|
Gastric emptying is measured using of 100 microliters of 13C Octanoic Acid breath test
|
Samples taken every 15 minutes for 3 hours
|
Chewing rate
Time Frame: At baseline
|
Chewing rate would be assessed with recording the preload breakfast meal provided and analysing the video recording in software (ELAN 6.4) for number of chews, bites, swallows, time of food in the mouth.
|
At baseline
|
Salivary flow rate
Time Frame: At baseline
|
Stimulated and unstimulated salivary flow rate would be assessed with passive drooling method.
|
At baseline
|
BMI
Time Frame: At baseline
|
BMI is assessed by using a body composition monitor (OMRON Viva)
|
At baseline
|
Oral Health
Time Frame: At baseline
|
Oral Health will be assessed by using an Oral Health Questionnaire
|
At baseline
|
Chewing ability
Time Frame: At baseline
|
Chewing ability will be assessed by using a colour mixing ability chewing gum test (Heu-Check test, University of Bern)
|
At baseline
|
Glucose
Time Frame: Every 15 minutes for the first hour after the meal and every 30 minutes thereafter till the end of the total 3 hours
|
Glucose will be assessed from finger prick blood samples
|
Every 15 minutes for the first hour after the meal and every 30 minutes thereafter till the end of the total 3 hours
|
Insulin
Time Frame: Every 15 minutes for the first hour after the meal and every 30 minutes thereafter till the end of the total 3 hours
|
Insulin will be assessed from finger prick blood samples
|
Every 15 minutes for the first hour after the meal and every 30 minutes thereafter till the end of the total 3 hours
|
Salivary a-amylase
Time Frame: At baseline
|

IPD Plan Description
No personal identification data will be shared.
The study is not under an obligation to share data, however, it is possible that some of the individual (unlinked / non-identifiable) data will be useful in a meta-analysis and, hence sharing individual participant data (IPD) will be considered.
