Impact of 5α-reductase inhibitor and α-blocker therapy for benign prostatic hyperplasia on prostate cancer incidence and mortality.

OBJECTIVE: To investigate the use of 5α-reductase inhibitors (5ARIs) and α-blockers among men with benign prostatic hyperplasia (BPH) in relation to prostate cancer (PCa) incidence, severity and mortality. PATIENTS AND METHODS: A retrospective 20-year cohort study in men residing in Saskatchewan, aged 40-89 years, with a BPH-coded medical claim between 1995 and 2014, was conducted. Cox proportional hazards regression was used to compare incidence of PCa diagnosis, metastatic PCa, Gleason score 8-10 PCa, and PCa mortality among 5ARI users (n = 4 571), α-blocker users (n = 7 764) and non-users (n = 11 677). RESULTS: In comparison with both non-users and α-blocker users, 5ARI users had a ~40% lower risk of a PCa diagnosis (11.0% and 11.4% vs 5.8%, respectively), and α-blocker users had an 11% lower risk of a PCa diagnosis compared with non-users. Overall, the incidence of metastatic PCa and PCa mortality was not significantly different among 5ARI or α-blocker users compared with non-users (adjusted hazard ratios [HR] of metastatic PCa: 1.12 and 1.13, respectively, and PCa mortality: 1.11 and 1.18, respectively, P > 0.05 for both drugs), but both 5ARI and a-blocker users had ~30% higher risk of Gleason score 8-10 cancer, adjusted HR 1.37, 95% confidence interval [CI] 1.03-1.82, P = 0.03, and adjusted HR 1.28, 95% CI 1.03-1.59, P = 0.02, respectively compared with non-users. CONCLUSION: The use of 5ARIs was associated with lower risk of PCa diagnosis, regardless of comparison group. Risk of high grade PCa was higher among both 5ARI users and α-blocker users compared with non-users; however, this did not translate into higher risk of PCa mortality.

Association of moderate to severe lower urinary tract symptoms with incident type 2 diabetes and heart disease.

PURPOSE: Increasing evidence suggests a possible link between lower urinary tract symptoms and chronic illnesses. We determined whether lower urinary tract symptoms are associated with incident type 2 diabetes and heart disease in a population based study. MATERIALS AND METHODS: BACH is a population based epidemiological survey of urological symptoms. A multistage, stratified, cluster sample design was used to obtain a random sample of 4,144 men and women 30 to 79 years old at baseline. Median followup was 4.8 years between baseline (2002 to 2005) and followup (2006 to 2010). Type 2 diabetes and heart disease were assessed by self-report. Lower urinary tract symptoms were assessed by the AUA-SI, and voiding and storage subscores. Logistic regression was used to estimate the OR and 95% CI, and adjust for potential confounders. RESULTS: In participants with a body mass index of 30 kg/m(2) or greater the adjusted ORs for incident heart disease were 1.89 (95% CI 1.05, 3.39) for AUA-SI 8 or greater and 2.32 (95% CI 1.33, 4.05) for a storage score of 4 or greater. In participants with abdominal obesity the adjusted ORs for incident type 2 diabetes were 2.06 (95% CI 1.19, 3.55) for AUA-SI 8 or greater and 1.81 (95% CI 1.04, 3.15) for a storage score of 4 or greater. Lower urinary tract symptoms (AUA-SI 8 or greater) were also predictive of type 2 diabetes in men and women younger than 50 years (adjusted OR 2.37, 95% CI 1.18, 4.80). CONCLUSIONS: Longitudinal results of BACH suggest that lower urinary tract symptoms are a marker of increased risk for type 2 diabetes and heart disease in obese men and women. The increased risk in younger men and women suggests that lower urinary tract symptoms may be an indicator of impending disease.

Associations between supplemental or dietary intake of vitamin C and severity of lower urinary tract symptoms.

OBJECTIVE: To examine the association between long-term dietary vitamin C intake and recent use of vitamin C supplements with the progression and severity of lower urinary tract symptoms (LUTS). PARTICIPANTS AND METHODS: Baseline and 5-year follow-up interviews were completed by 2825 black, Hispanic or white men and women aged 30-79 years in the Boston Area Community Health survey. Dietary and supplemental vitamin C intake was assessed using a validated food frequency questionnaire. LUTS were assessed using the validated American Urological Association Symptom Index. Multivariable models were used to test the associations between baseline vitamin C and progression of LUTS over the follow-up period, and between recent vitamin C intake and LUTS severity. RESULTS: In multivariable models, baseline dietary vitamin C was associated with lower odds of progression of daytime storage symptoms in men (e.g. quartile 4 vs 1, odds ratio [OR] = 0.63, 95% confidence interval [CI]: 0.41-0.97), or urgency symptoms in women (P trend = 0.02). Recent vitamin C intake at follow-up was also associated with better symptom scores among men. In contrast, among women, vitamin C supplement intake was associated with worse symptom scores, particularly daytime storage problems (500 mg/day vs none, OR = 1.66, 95% CI: 1.18-2.35, P trend = 0.01). Recent dietary vitamin C was not associated with LUTS in women. CONCLUSION: Vitamin C intake from foods and beverages was inversely associated with progression of daytime urinary storage symptoms in men or urgency symptoms in women at 5-year follow-up, therefore, the present results do not support a widespread avoidance for patients with LUTS of foods and beverages naturally rich in vitamin C. Supplemental vitamin C use above recommended daily intake levels was associated with higher odds of daytime urinary storage symptoms in women, and this finding is worthy of further attention and confirmation in future clinical trials.

Association of African genetic ancestry with fasting glucose and HbA1c levels in non-diabetic individuals: the Boston Area Community Health (BACH) Prediabetes Study.

AIMS/HYPOTHESIS: To test among diabetes-free urban community-dwelling adults the hypothesis that the proportion of African genetic ancestry is positively associated with glycaemia, after accounting for other continental ancestry proportions, BMI and socioeconomic status (SES). METHODS: The Boston Area Community Health cohort is a multi-stage 1:1:1 stratified random sample of self-identified African-American, Hispanic and white adults from three Boston inner city areas. We measured 62 ancestry informative markers, fasting glucose (FG), HbA1c, BMI and SES (income, education, occupation and insurance status) and analysed 1,387 eligible individuals (379 African-American, 411 Hispanic, 597 white) without clinical or biochemical evidence of diabetes. We used three-heritage multinomial linear regression models to test the association of FG or HbA1c with genetic ancestry proportion adjusted for: (1) age and sex; (2) age, sex and BMI; and (3) age, sex, BMI and SES. RESULTS: Mean age- and sex-adjusted FG levels were 5.73 and 5.54 mmol/l among those with 100% African or European ancestry, respectively. Using per cent European ancestry as the referent, each 1% increase in African ancestry proportion was associated with an age- and sex-adjusted FG increase of 0.0019 mmol/l (p = 0.01). In the BMI- and SES-adjusted model the slope was 0.0019 (p = 0.02). Analysis of HbA1c gave similar results. CONCLUSIONS/INTERPRETATION: A greater proportion of African genetic ancestry is independently associated with higher FG levels in a non-diabetic community-based cohort, even accounting for other ancestry proportions, obesity and SES. The results suggest that differences between African-Americans and whites in type 2 diabetes risk may include genetically mediated differences in glucose homeostasis.

Treatment status and progression or regression of lower urinary tract symptoms in a general adult population sample.

PURPOSE: We report progression and regression of lower urinary tract symptoms in a population based cohort by race/ethnicity, gender, age and lower urinary tract symptom medication use. MATERIALS AND METHODS: The BACH (Boston Area Community Health) Survey enrolled 5,502 participants 30 to 79 years old of black, Hispanic or white race/ethnicity. The 5-year followup interviews were completed by 1,610 men and 2,534 women for a conditional response rate of 80%. Population weighted estimates of lower urinary tract symptoms severity were assessed using the AUASI (American Urological Association symptom index) and analyzed using multivariate models. RESULTS: Symptom progression (increase in AUASI score of 3 or more points) was reported by 21% to 33% of participants and regression (decrease 3 or greater) by 30% to 44% of participants, most commonly women and Hispanic participants. Age and higher body mass index were associated with progression (p <0.01), but not with regression. Lower urinary tract symptom medication use at baseline only was associated with improved symptoms scores 5 years later (multivariate adjusted OR 3.10, 95% CI 1.28-7.51, compared to nonusers), whereas using medication at baseline and followup was associated with similar rates of progression and regression as observed among participants not using lower urinary tract symptom medication at either point. CONCLUSIONS: Lower urinary tract symptoms persisted at followup for approximately half of the population experiencing symptoms at baseline, including many men and women using lower urinary tract symptom medications. However, overall lower urinary tract symptom medication use and surgical treatment appeared beneficial for symptom control at 5-year followup. Age and body mass index were associated with symptom worsening, and Hispanic ethnicity was associated with greater symptom fluctuation. Clinicians should consider the higher likelihood of lower urinary tract symptom progression for older or heavier patients, and monitor responsiveness to lower urinary tract symptom medication.

Effects of patient medication requests on physician prescribing behavior: results of a factorial experiment.

BACKGROUND: Because of internet searches, advice from friends, and pharmaceutical advertising, especially direct-to-consumer advertising, patients are increasingly activated to request medications during a physician encounter. OBJECTIVES: To estimate the effect of patient requests for medications on physician-prescribing behavior, unconfounded by patient, physician, and practice-setting factors. RESEARCH DESIGN: Two experiments were conducted among 192 primary care physicians, each using different video-based scenarios: an undiagnosed "patient" with symptoms strongly suggesting sciatica, and a "patient" with already diagnosed chronic knee osteoarthritis. Half of patients with sciatica symptoms requested oxycodone, whereas the other half requested something to help with pain. Similarly, half of knee osteoarthritis patients specifically requested celebrex and half requested something to help with pain. SUBJECTS: To increase generalizability and ensure sufficient numbers were available, we recruited 192 primary care physicians from 6 US states. MEASURES: The primary outcome was whether physicians would accede to a patient's request for a medication. Alternative pain medications prescribed were secondary outcomes. RESULTS: 19.8% of sciatica patients requesting oxycodone would receive a prescription for oxycodone, compared with 1% of those making no specific request (P = 0.001). Fifty-three percent of knee osteoarthritis patients requesting celebrex would receive it, compared with 24% of patients making no request (P = 0.001). Patients requesting oxycodone were more likely to receive a strong narcotic (P = 0.001) and less likely to receive a weak narcotic (P = 0.01). Patients requesting celebrex were much less likely to receive a nonselective nonsteroidal anti-inflammatory drugs (P = 0.008). No patient attributes, physician, or organizational factors influenced a physician's willingness to accede to a patient's medication request. CONCLUSIONS: In both scenarios, activated patient requests for a medication substantially affected physician-prescribing decisions, despite the drawbacks of the requested medications.

Treatment status and risk factors for incidence and persistence of urinary incontinence in women.

INTRODUCTION AND HYPOTHESIS: The objective of this analysis was to describe urinary incontinence (UI) incidence and persistence over 5 years in association with treatment status, sociodemographic, medical, and lifestyle factors, in a racially/ethnically diverse population-based female sample. METHODS: The Boston Area Community Health Survey enrolled 3,201 women aged 30-79 years of black, Hispanic, and white race/ethnicity. Five-year follow-up was completed by 2,534 women (conditional response rate 83.4 %), allowing population-weighted estimates of UI incidence and persistence rates. Predictors of UI were determined using multivariate logistic regression models. RESULTS: Incidence of UI at least monthly was 14.1 % and weekly 8.9 %. Waist circumference at baseline and increasing waist circumference over 5-year follow-up were the most robust predictors of UI incidence in multivariate models (P ≤ 0.01). Among 475 women with UI at baseline, persistence was associated with depression symptoms [monthly UI, odds ratio (OR) = 2.39, 95 % confidence interval (CI) 1.14-5.02] and alcohol consumption (weekly UI, OR = 3.51, 95 % CI 1.11-11.1). Among women with weekly UI at baseline, 41.7 % continued to report weekly UI at follow-up, 14.1 % reported monthly UI, and 44.2 % had complete remission. Persistence of UI was not significantly higher (58.2 % vs. 48.0 %, chi-square P = 0.3) among untreated women. Surgical or drug treatment for UI had little impact on estimates for other risk factors or for overall population rates of persistence or remission. CONCLUSIONS: Women with higher gains in waist circumference over time were more likely to develop UI, but waist circumference was not predictive of UI persistence. UI treatments did not affect associations for other risk factors. Additional research on the role of alcohol intake in UI persistence is warranted.

Intake of caffeinated, carbonated, or citrus beverage types and development of lower urinary tract symptoms in men and women.

Evidence to substantiate recommendations for restriction of caffeinated or acidic beverages as self-management for lower urinary tract symptoms (LUTS) is limited. We examined longitudinal and acute associations between beverage intake and LUTS in the Boston Area Community Health (BACH) cohort (n = 4,144) between 2002 and 2010. Multivariable models tested associations between baseline intakes and progression of LUTS at 5-year follow-up, between follow-up intakes and International Prostate Symptom Scores at follow-up, and between 5-year intake changes and LUTS progression. Greater coffee or total caffeine intake at baseline increased the odds of LUTS progression in men (coffee: >2 cups/day vs. none, odds ratio = 2.09, 95% confidence interval: 1.29, 3.40, P-trend = 0.01; caffeine: P-trend < 0.001), particularly storage symptoms. Women who increased coffee intake by at least 2 servings/day during follow-up (compared with categories of decreased or unchanged intakes) had 64% higher odds of progression of urgency (P = 0.003). Women with recently increased soda intake, particularly caffeinated diet soda, had higher symptom scores, urgency, and LUTS progression. Citrus juice intake was associated with 50% lower odds of LUTS progression in men (P = 0.02). Findings support recommendations to limit caffeinated beverage intake for LUTS, and in men, they suggest benefits of citrus juice consumption. Further clinical research is warranted, particularly of the precise role of sodas containing artificial sweeteners in bladder sensations and urological function.

Association of lower urinary tract symptoms and the metabolic syndrome: results from the Boston area community health survey.

PURPOSE: In this study we investigated the relationship between lower urinary tract symptoms as defined by the American Urological Association symptom index and the metabolic syndrome, and determined the relationship between individual symptoms comprising the American Urological Association symptom index and the metabolic syndrome. MATERIALS AND METHODS: The Boston Area Community Health Survey used a 2-stage cluster design to recruit a random sample of 2,301 men 30 to 79 years old. Analyses were conducted on 1,899 men who provided blood samples. Urological symptoms comprising the American Urological Association symptom index were included in the analysis. The metabolic syndrome was defined using a modification of the Adult Treatment Panel III guidelines. The association between lower urinary tract symptoms and the metabolic syndrome was assessed using odds ratios and 95% confidence intervals estimated using logistic regression models. RESULTS: Increased odds of the metabolic syndrome were observed in men with mild to severe symptoms (American Urological Association symptom index 2 to 35) compared to those with an American Urological Association symptom index score of 0 or 1 (multivariate OR 1.68, 95% CI 1.21-2.35). A statistically significant association was observed between the metabolic syndrome and a voiding symptom score of 5 or greater (multivariate adjusted OR 1.73, 95% CI 1.06-2.80) but not for a storage symptom score of 4 or greater (multivariate adjusted OR 0.94, 95% CI 0.66-1.33). Increased odds of the metabolic syndrome were observed even with mild symptoms, primarily for incomplete emptying, intermittency and nocturia. These associations were observed primarily in younger men (younger than 60 years) and were null in older men (60 years old or older). CONCLUSIONS: The observed association between urological symptoms and the metabolic syndrome provides further evidence of common underlying factors between lower urinary tract symptoms and chronic conditions outside the urinary tract.

Common prescription medication use and erectile dysfunction: results from the Boston Area Community Health (BACH) survey.

OBJECTIVE: To investigate the association of erectile dysfunction (ED) with commonly used medications including antihypertensive treatment (AHT), psychoactive medication and pain and anti-inflammatory medication. SUBJECTS AND METHODS: The Boston Area Community Health (BACH) survey used a multistage stratified design to recruit a random sample of 2301 men aged 30-79 years. ED was assessed using the five-item International Index of Erectile Function (IIEF-5). Prescription medications, captured using a combination of drug inventory and self-report with a prompt by indication, included in this analysis comprised AHT, psychoactive medication, and pain and anti-inflammatory medication. Logistic regression was used to estimate the odds ratios (ORs) of the association of medication use with ED and to adjust for potential confounders including age, comorbid conditions and sociodemographic and lifestyle factors. RESULTS: Multivariable analyses showed benzodiazepines (adjusted OR = 2.34, 95% confidence interval [CI]: 1.03, 5.31) and tricyclic antidepressants (adjusted OR = 3.35, 95% CI: 1.09, 10.27) were associated with ED, while no association was observed for serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors and atypical antipsychotics. The use of AHT, whether in monotherapy or in conjunction with other AHTs, and pain or anti-inflammatory medications were not associated with ED after accounting for confounding factors. CONCLUSIONS: Results of the BACH survey suggest adverse effects of some psychoactive medications (benzodiazepines and tricyclic antidepressants). No evidence of an association of AHT or pain and anti-inflammatory medication with ED was observed.

Prevalence and overlap of childhood and adult physical, sexual, and emotional abuse: a descriptive analysis of results from the Boston Area Community Health (BACH) survey.

Abuse is associated with a wide variety of health problems, yet comprehensive population-based data are scant. Existing literature focuses on a single type of abuse, population, or lifestage. Using a racially/ethnically diverse community-based sample, we document the prevalence of physical, emotional, and sexual abuse by lifestage and gender, assess variation in abuse by sociodemographics; establish overlap of abuses; and examine childhood abuse relationships with abuse in adulthood. Prevalence of abuse ranges from 15% to 27%; women report more adulthood emotional abuse and lifetime sexual abuse than men; reports of abuse can vary by race/ethnicity and poverty status, particularly in women; there is overlap between types of abuse; and a history of childhood abuse is associated with a greater risk of abuse as an adult.

Are physical activity, smoking and alcohol consumption associated with lower urinary tract symptoms in men or women? Results from a population based observational study.

PURPOSE: Lower urinary tract symptoms are highly prevalent and reduce quality of life. Lifestyle behaviors and the development of lower urinary tract symptoms have been largely unexamined. We investigated physical activity, smoking and alcohol drinking in relation to the development of lower urinary tract symptoms in men and women. MATERIALS AND METHODS: Data were obtained from the BACH (Boston Area Community Health) Survey, a longitudinal observational study. Baseline (2002 to 2005) in-person interviews assessed activity, smoking and alcohol consumption. Five-year followup interviews (2006 to 2010 in 4,145) assessed new reports of moderate to severe lower urinary tract symptoms defined by the AUASI (AUA symptom index). Analysis was conducted using multivariable logistic regression. RESULTS: Lower urinary tract symptoms developed in 7.7% and 12.7% of at-risk men and women, respectively. Women were 68% less likely to experience lower urinary tract symptoms (OR 0.32; 95% CI 0.17, 0.60; p <0.001) if they had high vs low levels of physical activity. Although the association was similar among men, it was not statistically significant upon adjustment for medical or sociodemographic characteristics in the multivariable model. Women smokers were twice as likely to experience lower urinary tract symptoms, particularly storage symptoms (OR 2.15; 95% CI 1.30, 3.56; p = 0.003), compared to never smokers. Among men, smoking was not associated with lower urinary tract symptoms. Results for alcohol intake were inconsistent by intake level and symptom subtype. CONCLUSIONS: A low level of physical activity was associated with a 2 to 3 times greater likelihood of lower urinary tract symptoms. Smoking may contribute to the development of lower urinary tract symptoms in women but not in men. Clinicians should continue to promote physical activity and smoking cessation, noting the additional potential benefits of the prevention of lower urinary tract symptoms, particularly for women.

Associations of commonly used medications with urinary incontinence in a community based sample.

PURPOSE: We examined the association between the use of medications and the prevalence of urinary incontinence in gender specific analyses of a community based, representative sample. MATERIALS AND METHODS: A population based epidemiological study was conducted of 5,503 men and women 30 to 79 years old residing in Boston, Massachusetts (baseline data collected from 2002 to 2005). Urological symptoms were ascertained in a 2-hour, in person interview. Urinary incontinence was defined as urine leakage occurring weekly or more often during the last year. Medications used in the last month were considered current use. Associations of 20+ medications and prevalent urinary incontinence were examined using multivariate logistic regression (ORs and 95% CIs) with adjustments for known urinary incontinence risk factors. RESULTS: The prevalence of urinary incontinence in the analysis sample was 9.0% in women and 4.6% in men. For women the prevalence was highest among users of certain antihistamines (28.4%) and angiotensin II receptor blockers (22.9%). For men the prevalence was highest among angiotensin II receptor blocker (22.2%) and loop diuretic (19.1%) users. After final multivariate adjustment there were significant positive associations for certain antihistamines, beta receptor agonists, angiotensin II receptor blockers and estrogens with urinary incontinence in women (all ORs greater than 1.7), and a borderline significant association for anticonvulsants (OR 1.75; 95% CI 1.00, 3.07). Among men only anticonvulsants were associated with urinary incontinence after final adjustments (OR 2.50; 95% CI 1.24, 5.03), although angiotensin II receptor blockers showed an adjusted association of borderline significance (OR 2.21; 95% CI 0.96, 5.10). CONCLUSIONS: Although a cross-sectional analysis cannot determine causality, our analysis suggests certain medications should be further examined in longitudinal analyses of risk to determine their influence on urological symptoms.

Non steroidal anti-inflammatory drug use and levels of oestrogens and androgens in men.

OBJECTIVE: Studies suggest that regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) may lower oestrogen levels in women. However, no large, population-based studies have assessed NSAID/hormone associations in men. Our objective was to examine the association between use of prescription and over-the-counter NSAIDs, and levels of oestrogens and androgens in men. DESIGN: The Boston Area Community Health Survey, an observational survey with initial data collection in 2002-2005. PATIENTS: A total of 1766 men who provided a blood sample and data on recent analgesic use. MEASUREMENTS: Adjusted geometric mean levels of androgens, oestrogens, SHBG, LH and FSH for each category of NSAID use and the per cent difference in hormone levels for users vs nonusers. RESULTS: There was no significant association between prescription/over-the-counter NSAID use and any hormone examined after adjustment for potential confounders. For example, geometric mean testosterone levels were 13·8, 13·6 and 14·2 nM in nonusers, prescription users and over-the-counter NSAID users, respectively; the corresponding levels for estradiol were 80·3, 70·4 and 79·9 pM. In stratified analyses, however, prescription NSAID use was associated with lower testosterone, estradiol and estrone levels in obese men and lower testosterone and dehydroepiandrosterone sulphate levels in inactive men. CONCLUSIONS: While overall these data do not provide strong support for an association between NSAID use and hormone levels in men, prescription NSAIDs may decrease levels of certain oestrogens and androgens in obese and inactive men.

Association of overactive bladder and C-reactive protein levels. Results from the Boston Area Community Health (BACH) Survey.

OBJECTIVE: • To investigate the association between overactive bladder (OAB) and C-reactive protein (CRP) in a population-based sample of men and women. SUBJECTS AND METHODS: • Epidemiological survey of urological symptoms among men and women aged 30-79 years. A multi-stage stratified cluster design was used to randomly sample 5503 adults from the city of Boston. Analyses were conducted on 1898 men and 1854 women with available CRP levels. • The International Continence Society defines OAB as 'Urgency with or without urge incontinence, usually with frequency and nocturia.' OAB was defined as: (1) urgency, (2) urgency with frequency, and (3) urgency with frequency and nocturia. • Odds ratios (OR) and 95% confidence intervals (95% CI) of the CRP and OAB association were estimated using logistic regression. RESULTS: • Prevalence of OAB increased with CRP levels in both men and women. • In men, adjusted ORs (95% CI) per log(10) (CRP) levels were 1.90 (1.26-2.86) with OAB defined as urgency, 1.65 (1.06-2.58) with OAB defined as urgency and frequency, and 1.92 (1.13-3.28) with OAB defined as urgency, frequency and nocturia. • The association was more modest in women with ORs (95% CI) of 1.53 (1.07-2.18) for OAB as defined urgency, 1.51 (1.02-2.23) for OAB defined as urgency and frequency, and 1.34 (0.85-2.12) for OAB defined as urgency, frequency and nocturia. CONCLUSIONS: • Results show a consistent association of increasing CRP levels and OAB among both men and women. • These results support our hypothesis for the role of inflammation in the development of OAB and a possible role for anti-inflammatory agents in its treatment.

Commonly used antihypertensives and lower urinary tract symptoms: results from the Boston Area Community Health (BACH) Survey.

UNLABELLED: Study Type - Prevalence (inception cohort) Level of Evidence 1b What's known on the subject? and What does the study add? Certain antihypertensives, particularly diuretics and calcium channel blockers, are known to be associated with increased risk of LUTS including nocturia, but little is known about gender-specific effects. This is the first epidemiological study, to our knowledge, to compare the prevalence of several urological symptoms (storage, voiding and nocturia) among male and female users of a wide variety of common antihypertensives using a community-based sample. OBJECTIVE: To examine differences in the prevalence of lower urinary tract symptom (LUTS) among users of five common AHT classes compared with non-users, adjusted for LUTS risk factors in a large, representative sample. SUBJECTS AND METHODS: Data were from the Boston Area Community Health Survey, a population-based study of community-dwelling male and female (30-79 years) residents of Boston, MA, USA for whom prescription drug information was collected between 2002 and 2005. The urological symptoms of storage, voiding, and nocturia were assessed using interviewer-administered questionnaires and the American Urological Association Symptom Index. This analysis was conducted among 1865 participants with an AHT indication. Associations of angiotensin-converting enzyme inhibitors, beta blockers, calcium channel blockers (CCBs) and loop and thiazide diuretics with the three groups of LUTS were estimated using odds ratios (ORs) and 95% confidence intervals (CIs) from multivariate logistic regression (referent group: untreated hypertension). Overlap in use was accounted for using monotherapy and combination therapy exposure categories. RESULTS: Among women, monotherapy with CCBs was associated with increased prevalence of nocturia (OR = 2.65, 95% CI: 1.04-6.74) and voiding symptoms (OR = 3.84, 95% CI: 1.24-11.87); these results were confined to women aged <55 years. Among men of all ages, positive associations were observed for thiazides and voiding symptoms (monotherapy OR = 2.90, 95% CI: 1.17-7.19), and loop diuretics and nocturia (combination therapy OR = 2.55, 95% CI: 1.26-5.14). CONCLUSION: Results are consistent with the hypothesis that certain AHTs may aggravate LUTS. The presence of new or worsening LUTS among AHT users suggests medications should be reviewed and a change in AHT class considered.

Characteristics of persons with overactive bladder of presumed neurologic origin: results from the Boston Area Community Health (BACH) survey.

AIMS: To compare the descriptive epidemiology of overactive bladder (OAB) of presumed neurologic origin (NOAB) to OAB of non-neurologic origin (N-NOAB). METHODS: Five thousand five hundred three community-dwelling persons aged 30-79 were interviewed regarding urologic symptoms (2002-2005). NOAB was defined as symptoms of urgency and/or urgency incontinence among those with a self-reported history of healthcare provider diagnosed stroke (N = 98), multiple sclerosis (N = 21), or Parkinson's disease (N = 7). N-NOAB was defined identically but occurring among those not reporting neurologic disease (ND). Prevalence estimates were weighted to reflect sampling design; chi-square, Fisher's exact, or t-tests were used to test differences. Urologic symptom interference was assessed using the Epstein scale, while the impact of urinary incontinence (UI) on health-related quality-of-life (HRQOL) was measured using a modification of the Incontinence Impact Questionnaire-7. RESULTS: Forty-five (31.0%) of 125 persons with ND and 994 (16.7%) of 5378 persons without ND reported OAB symptoms. The overall prevalence of NOAB and N-NOAB was 0.6% and 16.4%, respectively. Persons with NOAB had higher (worse) mean American Urologic Association Symptom Index scores (13.0 vs. 10.0, P = 0.09) compared to those with N-NOAB, and were significantly more likely to have diabetes, high blood pressure, cardiac disease, and fair/poor self-reported health (all P < 0.05). Mean symptom interference and UI HRQOL scores were significantly higher (worse) in the NOAB group compared to persons with N-NOAB (all P < 0.05). CONCLUSIONS: Persons with NOAB appeared to have a greater burden of urologic illness with respect to symptom interference and HRQOL compared to persons with N-NOAB.

Are commonly used psychoactive medications associated with lower urinary tract symptoms?

PURPOSE: Lower urinary tract symptoms (LUTS) such as urinary frequency and urgency are bothersome and associated with reduced quality of life. Atypical antipsychotics (AAPs) have been implicated in increasing the risk of urinary incontinence. In a large community-based sample of men and women, we examined the associations of AAP and selective serotonin reuptake inhibitor (SSRIs) use with LUTS. METHODS: Data were collected (2002-2005) from a generalizable sample of Boston, MA, USA, residents aged 30-79 (N = 5503). LUTS were assessed using the American Urologic Association Symptom Index (AUA-SI). The prevalence of clinically-significant LUTS was estimated using a cutoff AUA-SI score of 8+ to indicate moderate-to-severe symptoms. Confounder-adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated from multivariate logistic regression to estimate the associations for psychoactive drugs used in the previous month (SSRIs, AAPs, both) and LUTS. RESULTS: Among women, AAP users had a higher prevalence of LUTS (46.2%) compared with SSRI users (23.5%) and those with depressive symptoms not using SSRIs or AAPs (26.3%). Corresponding prevalence estimates among men were 32.7%, 29.8%, and 33.3%. In multivariate models, AAP use was significantly associated with LUTS among women when used either with (OR = 2.72, 95% CI:1.45-5.10) or without (OR = 3.05, 95% CI:1.30-7.16) SSRIs, but SSRI use without AAP use was not associated with LUTS compared with nonusers without depressive symptoms. No associations were observed among men. CONCLUSIONS: In our study, AAPs but not SSRIs were associated with increased prevalence of LUTS among women only. Further prospective research is needed to determine time sequence and cause and effect.

Nonsteroidal antiinflammatory drug use and lower urinary tract symptoms: results from the Boston area community health survey.

There is evidence for a role of inflammation in the etiology of lower urinary tract symptoms (LUTS), raising the possibility that use of nonsteroidal antiinflammatory drugs (NSAIDs) may inhibit the development or progression of LUTS. The authors examined the association between use of prescription and over-the-counter NSAIDs and LUTS among 1,974 men and 2,661 women in the Boston Area Community Health Survey (2002-2005). Multivariable-adjusted logistic regression was used to estimate odds ratios and 95% confidence intervals for LUTS, voiding symptoms, storage symptoms, and nocturia. There was no clear association between use of prescription or over-the-counter NSAIDs (compared with no NSAID use) and overall LUTS, voiding symptoms, or nocturia in men or women. However, over-the-counter NSAID use was positively associated with storage symptoms in women (odds ratio = 1.37, 95% confidence interval: 1.03, 1.83), and there was a positive association between over-the-counter NSAID use and overall LUTS among women with a history of arthritis (odds ratio = 2.09, 95% confidence interval: 1.20, 3.64). These results do not provide strong support for an association between NSAIDs and LUTS. However, the associations between over-the-counter NSAID use and certain urologic symptoms, particularly among women with arthritis, and the potential mechanisms involved should be evaluated in future studies.

The association of adiposity and overactive bladder appears to differ by gender: results from the Boston Area Community Health survey.

PURPOSE: We investigate the association of different measures of adiposity (waist circumference, hip circumference, waist-to-hip ratio and body mass index) with overactive bladder (urinary frequency and urgency), whether the association varies by gender or age and whether it persists when models are adjusted for other confounders. MATERIALS AND METHODS: Data were from the Boston Area Community Health epidemiological survey, a random sample of 5,503 Boston, Massachusetts, residents 30 to 79 years old with equal representation from 3 racial/ethnic groups (black, Hispanic and white). Statistical analysis involved nonparametric loess models and multivariate logistic regression. RESULTS: We noted distinct patterns by gender for the association of various adiposity measures with overactive bladder. Waist-to-hip ratio was not significantly associated with overactive bladder in either gender. In women the prevalence of overactive bladder increased as waist (OR adjusted for other confounders 1.10/10 cm increase) or hip circumference (OR 1.12/10 cm increase) or body mass index (OR 1.03/kg/m2 increase) increased. In men the prevalence of overactive bladder decreased as adiposity increased (OR 0.65/10 cm increase in waist circumference, OR 0.71/10 cm increase in hip circumference and OR 0.87/kg/m2 in body mass index) but only to a certain point (waist circumference 100 cm, hip circumference 115 cm and body mass index 27.5 kg/m2, respectively). At that point the prevalence of overactive bladder increased with increasing adiposity (OR 1.19/10 cm increase in waist circumference, OR 1.16/10 cm increase in hip circumference and OR 1.08/kg/m2 in body mass index). CONCLUSIONS: The relationship between adiposity and overactive bladder varies by gender.
