Objective: The aim of this study was to investigate the relationships between Geriatric Oral Health Assessment Index (GOHAI) and general physical status among community-dwelling older adults.
Background: Geriatric Oral Health Assessment Index is a patient-centred assessment of oral health for older adults. We hypothesised that GOHAI is a significant indicator of general physical status of older adults.
Methods: This study included 354 adults (age, ≥65 years) living independently. Body mass index, handgrip strength and one-leg standing time with eyes open were used to evaluate the general physical status. Spearman's rank correlation coefficients were calculated to examine the relationships between the GOHAI scores, its three subdivided categories (physical function, psychological function and pain and discomfort) and each physical status measurement. A stepwise linear regression model was applied with each physical status measurement as the dependent variable and the GOHAI scores and its subdivisions as the principal independent variable.
Results: Positive correlations were found between the GOHAI scores, its three subdivided categories and handgrip strength. The physical function category positively correlated with one-leg standing time. The GOHAI and the pain and discomfort category scores were retained in the final models of stepwise regression for handgrip strength, and significant relationships persisted after adjustments for demographic, psychosocial, medical and dental status.
Conclusion: The GOHAI scores and its pain and discomfort category score may be significant indicators of body muscle strength.
