The Correlation Among Nutrition, Muscle Strength, Masticatory and Swallow Ability of Inpatient Elders (NMM)

The masticatory performance would affect the nutritional status of elderly people. the prevalence of undernutrition among elderly inpatients is %20-50%. Previous related studies investigate the masticatory performance with special chewing gum and self-reported questionnaires. This study observes the correlation of masticatory muscles sEMG, nutritional status, and handgrip force among elderly inpatients.

Study Overview

• Status: Completed
• Conditions: Malnutrition; Moderate
• Intervention / Treatment: Other: No intervention

Detailed Description

In this cross-sectional study, we enrolled 120 seniors aged 65 and above who are newly admitted to the Asian University Hospital. Within 24 hours they admitted to the hospital, we collected the Mini Nutritional Assessment scores, surface electromyography data, handgrip strength, self-assessment swallowing ability score, and clinical objective data. We performed the statistics for independent t-test, Pearson correlation analysis, and binary logistic regression with SPSS 23 software.

Study Population

We enrolled 120 elderly inpatients in Asia University Hospital, Taiwan. We included new elderly inpatients aged 65 years or older who were able to communicate and were clearly conscious.

Description

Inclusion Criteria:

• new elderly inpatients aged 65 years or older who were able to communicate and were clearly conscious

Exclusion Criteria:

• Elderly individuals who were diagnosed with gastrointestinal (GI) dysfunction, dysphagia, edentulism without rehabilitation with dentures, brain disease, stroke or cancer were excluded due to the possibility of dysphagia, cachexia or masticatory muscle palsy.
