Risk factors associated with overactive bladder severity in patients with type 2 diabetes

The prevalence of overactive bladder (OAB) is known to be higher in patients with type 2 diabetes (T2DM) however there are not many studies about specific risk factors contributing to its progression among diabetes mellitus (DM) patients, so this study aimed to investigate the risk factors specific to DM that influence the progression of OAB in Syrian population.

This cross-sectional study was carried out at five endocrinology centers situated in four Syrian provinces: Damascus, Aleppo, Homs, Hama, and Latakia. The study comprised patients who were diagnosed with both T2DM and OAB and had visited these centers from March 2020 and February 2024. The Arabic version of the OAB Symptom Score (OABSS) scale was used to categorize the participants based on the severity score into two groups: the mild OAB group and the moderate-severe OAB group. A logistic analysis was conducted to assess the risk factors associated with the progression of OAB among patients with diabetes.

Among the 186 patients diagnosed with both DM and OAB, significant distinctions were found between the two groups concerning the severity of OAB, age, duration of diabetes, symptomatic diabetic peripheral neuropathy (DPN), and ankle reflex (p < 0.05). Furthermore, a multivariate analysis revealed that age (odds ratio [OR] 1.07, 95% confidence interval [CI] 0.68-1.58), duration of diabetes (OR 2.14, 95% CI 1.75-3.74), and symptomatic DPN (OR 2.47, 95% CI 1.17-3.54) independently acted as risk factors for the advancement of OAB.

The progression of OAB in Syrian patients with diabetes is closely associated with the severity of DM. Factors such as age, duration of diabetes, and symptomatic DPN are independent predictors of the severity of OAB. Patients who experience symptomatic DPN are at an increased risk of developing OAB.
