Antihypertensive Drug Class Use and Differential Risk of Urinary Incontinence in Community-Dwelling Older Women
ABSTRACT BACKGROUND: Medication use is a potentially reversible cause of urinary incontinence (UI). The objective of this longitudinal cohort study was to evaluate whether self-reported UI in community-dwelling older women is associated with the use of different classes of antihypertensive agents. METHODS: The sample consisted of 959 black and white women aged 72-81 years without baseline (Year 1) UI from the Health, Aging, and Body Composition Study. Use of any antihypertensive from 10 drug classes (ie, alpha blockers [central], alpha blockers [peripheral], angiotensin-converting enzyme inhibitors, angiotensin-II receptor blockers, beta blockers, calcium channel blockers, diuretics [loop], diuretics [potassium-sparing], diuretics [thiazide], and vasodilators) was determined during Year 3 in-person interviews. The number of unique antihypertensive agents used and the standardized daily dosage were also examined. Self-reported UI, operationally defined as leaking urine at least weekly during the previous 12 months, was assessed at Year 4 visits. RESULTS: A total of 197 women (20.5%) reported UI at Year 4. Although any antihypertensive use, number of agents used, and standardized daily dosage at Year 3 were not associated with UI at Year 4, use of one particular drug class-peripheral alpha blockers (ie, doxazosin, prazosin, and terazosin)-was associated with fourfold greater odds of UI (adjusted odds ratio = 4.47; 95% confidence interval = 1.79-11.21; p = .0014). Further, in post hoc analyses, these odds nearly doubled in those also taking loop diuretics (adjusted odds ratio = 8.81; 95% confidence interval = 1.78-43.53; p = .0076). CONCLUSION: In community-dwelling older women, peripheral alpha blocker use was associated with UI, and the odds nearly doubled when used with loop diuretics.

ABSTRACT: Objective. To determine baseline variables associated with urgency urinary incontinence (UUI) in women presenting for stress urinary incontinence (SUI) surgery. Methods. Baseline data from two randomized trials enrolling 1,252 women were analyzed: SISTEr (fascial sling versus Burch colposuspension) and TOMUS (retropubic versus transobturator midurethral sling). Demographic data, POP-Q measures, and validated measures of symptom severity and quality of life were collected. Charlson Comorbidity Index (CCI) and Patient Health Questionnaire-9 were measured in TOMUS. Multivariate models were constructed with UUI and symptom severity as outcomes. Results. Over two-thirds of subjects reported bothersome UUI at baseline. TOMUS patients with more comorbidities had higher UDI irritative scores (CCI score 0 = 39.4, CCI score 1 = 42.1, and CCI score 2+ = 51.0, P = 0.0003), and higher depression scores were associated with more severe UUI. Smoking, parity, prior incontinence surgery/treatment, prolapse stage, and incontinence episode frequency were not independently associated with UUI. Conclusions. There were no modifiable risk factors identified for patient-reported UUI in women presenting for SUI surgery. However, the direct relationships between comorbidity level, depression, and worsening of UUI/urgency symptoms may represent targets for preoperative intervention. Further research is necessary to elucidate the pathophysiologic mechanisms that explain the associations between these medical conditions and bladder function.Advances in Urology 11/2013; 2013:567375.
