Association between Sarcopenia and Overactive Bladder in Elderly Diabetic Patients

Area of Science:

• Gerontology
• Urology
• Endocrinology

Background:

• Overactive bladder (OAB) and sarcopenia are common conditions in elderly populations.
• Diabetes mellitus is a prevalent comorbidity in the elderly, potentially exacerbating both OAB and sarcopenia.

Purpose of the Study:

• To investigate the association between sarcopenia and overactive bladder (OAB) in elderly diabetic patients.
• To utilize the Japanese version of the SARC-F questionnaire (SARC-F-J) for sarcopenia assessment.

Main Methods:

• A cross-sectional study involving 329 elderly diabetic patients (≥65 years) from a Japanese outpatient clinic.
• OAB was assessed using the OAB symptom score, and sarcopenia using the SARC-F-J questionnaire.
• Multiple logistic regression analysis was employed to calculate the odds ratio for OAB due to sarcopenia.

Main Results:

• 22.9% of participants had sarcopenia and 18.7% had OAB.
• Sarcopenia was significantly associated with OAB in elderly diabetic males, with an odds ratio of 4.46 (95% CI, 1.14-17.36, P = 0.031).
• The association was not statistically significant in females (OR, 2.09; 95% CI, 0.52-8.26; P = 0.293).

Conclusions:

• Sarcopenia, as assessed by SARC-F-J, is significantly associated with OAB in elderly diabetic male patients.
• Clinicians should consider the potential development of OAB during medical examinations of elderly diabetic males diagnosed with sarcopenia.
