Walking Speed Is Better Than Hand Grip Strength as an Indicator of Early Decline in Physical Function with Age in Japanese Women Over 65: A Longitudinal Analysis of the Tanno-Sobetsu Study Using Linear Mixed-Effects Models

Association between oral frailty and lower urinary tract symptoms among middle-aged and older adults in community-dwelling individuals: a cross-sectional study

PURPOSE

We assessed the association between oral frailty risk and LUTS among middle-aged and older adults in a community-dwelling population.

METHODS

This cross-sectional study was conducted among 586 subjects aged ≥ 40 years who participated in the Iwaki Health Promotion Project in Hirosaki, Japan. We used the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS) to assess LUTS. LUTS was defined as an IPSS score of 8 or higher or meeting diagnostic criteria for OAB. Oral frailty risk was defined as experiencing two or more of the following: decreased chewing ability, decreased biting force, and dry mouth sensation. Physical performance (10-m gait speed and grip strength) was used for analysis. The association between oral frailty risk and LUTS was examined using multivariate logistic regression analyses.

RESULTS

The study included 218 men and 370 women, of whom 140 had LUTS. The mean age of this cohort was 59 years. Significant differences were observed between the LUTS and non-LUTS groups, including age, hypertension, history of CVD, depressive status, sleep disturbance, and 10 m gait speed. The prevalence of oral frailty risk was significantly higher in the LUTS group than in the non-LUTS group (26% vs. 11%, P < 0.001). Multivariate analysis revealed that age, male gender, and oral frailty risk (odds ratio: 2.67, 95% confidence interval: 1.57-4.51, P < 0.001) were independent factors for LUTS. Moreover, oral frailty risk was an independent factor in both participants aged < 65 years and participants aged ≥ 65 years.

CONCLUSIONS

Oral frailty was independently associated with LUTS.
