Tokyo, Sept. 5 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062820) titled 'A study of how visual and auditory information during eating affects chewing and food texture perception in older adults' on Sept. 4.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Open -no one is blinded Control - No treatment

Primary Sponsor: Institute - Kobe Gakuin University

Condition: Condition - Healthy older adults Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To investigate the immediate effects of visual information and chewing-synchronized auditory feedback on chewing behavior, perceived food texture, and eating experience in community-dwelling older adults aged 65 years or older. In addition, associations between individual responses to visual and auditory feedback and oral function, frailty, muscle strength, and muscle mass will be explored. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - No-presentation condition. Participants will consume approximately 4.0 g of texture-modified food per trial without visual information or pseudo-chewing sound. Three trials will be performed under this condition. The order of the four conditions will be randomized for each participant, with a rest period of 1 to 2 minutes between conditions. Interventions/Control_2 - Visual-information condition. While consuming approximately 4.0 g of texture-modified food per trial, participants will view an image of the corresponding regular-texture food on a tablet device. No pseudo-chewing sound will be presented. Three trials will be performed under this condition.

Eligibility: Age-lower limit - 65 years-old <= Age-upper limit - Not applicable Gender - Male and Female Key inclusion criteria - Community-dwelling older adults aged 65 years or older. Individuals who routinely consume food orally. Individuals who are able to chew and swallow food independently. Individuals who are able to consume the test food used in this study. Individuals who understand the study explanation and provide written informed consent. Individuals who are able to perceive the visual and auditory information used in the study, with corrective devices such as glasses or hearing aids if necessary. Key exclusion criteria - Individuals who routinely require texture-modified diets or professional management for eating or swallowing. Individuals judged unable to safely consume the test food because of frequent coughing, choking, or similar problems during meals. Individuals with a food allergy to the test food. Individuals who have been instructed by a physician or other healthcare professional to restrict consumption of the test food or salt intake. Individuals who have difficulty performing repeated chewing because of temporomandibular joint pain, oral pain, or other conditions. Individuals in whom surface electrodes cannot be applied to the masseter region because of skin disorders or other conditions. Individuals judged by the principal investigator to be unsuitable for safe participation in the study. Target Size - 30
