Toileting behaviors and overactive bladder in patients with type 2 diabetes: a cross-sectional study in China

Overactive bladder is more prevalent in patients with type 2 diabetes than in those without diabetes. Unhealthy toileting behaviors may be associated with the development and worsening of overactive bladder symptoms. However, little is known about the relationships between toileting behaviors and overactive bladder in patients with diabetes. This study aimed to identify unhealthy toileting behaviors that patients with type 2 diabetes adopted to empty their bladders and investigate the relationships between toileting behaviors and overactive bladder.

Patients with type 2 diabetes from the endocrinology outpatient department of a hospital in China were recruited. The Toileting Behaviors-Women's Elimination Behavior and Overactive Bladder Symptom Score questionnaires were used to assess the patients' toileting behaviors and overactive bladder symptoms. A multivariate logistic regression model was used to explore the relationships between toileting behaviors and overactive bladder.

Almost 14% of patients with diabetes had overactive bladder. The unhealthiest toileting behavior was premature voiding. In the multivariate logistic regression analysis, premature voiding (OR = 1.286, p = 0.016) and straining to void (OR = 1.243, p = 0.026) were associated with overactive bladder. There was a greater likelihood of having overactive bladder when patients engaged in unhealthy toileting behaviors (premature voiding and straining to void).

Overactive bladder in patients with type 2 diabetes was more than twofold higher than that in the general population. Thus, overactive bladder is not just an inconsequential condition for patients with diabetes. Unhealthy toileting behaviors, e.g., premature voiding and straining to void, may contribute to the onset or worsening of overactive bladder in patients with diabetes. Identification and awareness of these modifiable behavioral factors during diabetes care is an essential component of primary prevention, alleviation, and management of overactive bladder symptoms.
