Clinical Trial Summary

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).

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective appetite assessment: Ad-libitum meal consumption	Consumption of the ad-libitum meal is measured (g). Participants are instructed to eat until they feel comfortable full	20 minutes
Secondary	Subjective appetite assessment: VAS	Appetite are assessed using a 100 mm Visual Analogue Scales (VAS, scale 0-100)	Every 30 minutes for 3 hours
Secondary	Gastric Emptying	Gastric emptying is measured using of 100 microliters of 13C Octanoic Acid breath test	Samples taken every 15 minutes for 3 hours
Secondary	Chewing rate	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
Secondary	Salivary flow rate	Stimulated and unstimulated salivary flow rate would be assessed with passive drooling method.	At baseline
Secondary	BMI	BMI is assessed by using a body composition monitor (OMRON Viva)	At baseline
Secondary	Oral Health	Oral Health will be assessed by using an Oral Health Questionnaire	At baseline
Secondary	Chewing ability	Chewing ability will be assessed by using a colour mixing ability chewing gum test (Heu-Check test, University of Bern)	At baseline
Secondary	Glucose	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
Secondary	Insulin	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
Secondary	Salivary a-amylase	Salivary a-amylase activity will be assessed from the stimulated saliva collected, by using a-amylase kinetic kit	At baseline
