2. Why this study? OAB is generally under treated and under diagnosed More reports on urge incontinence, not on OAB OAB reports on men is scarce, in particular in Asia

3. Objectives Determine the prevalence of OAB in Asian malesDetermine the prevalence of OAB in Asian males Determine the status of OAB as a problemDetermine the status of OAB as a problem Determine the demographic factors related to the occurrence of OABDetermine the demographic factors related to the occurrence of OAB Determine the degree of bother and treatment seeking rate in Asian menDetermine the degree of bother and treatment seeking rate in Asian men

4. Methodology Methodology Questionnaire based surveyQuestionnaire based survey –Created by an expert panel –Translated into the local dialect, validated –Multiple-choice type of queries –Self-administered under supervision of a medically-trained personnel

5. Survey Population TOTAL: Males : 2369TOTAL: Males : 2369 Participating countriesParticipating countries –Philippines –PhilippinesChina –IndonesiaMalaysia –SingaporeThailand –Hong Kong Taiwan –Korea India –Pakistan

6. The OAB (ICS, 2001) Urgency with or without urge incontinence usually with frequency and nocturia

7. Urgency = having strong desire to void urine Urge incontinence = involuntary loss of urine with urgency Frequency = voiding of > 8 times a day Nocturia = voiding of urine at night time Definitions

8. Country specific prevalence of OAB

9. Prevalence of OAB among males *** ** * Moorthy et al. 2004 (general pop.) ** Geirsson et al. 1993 (general pop.) *** Milsom et al., 2000 (general pop.) *

10. Distribution of different OAB symptoms in Asian males A = Frequency B = Urgency C = Frequency and Urgency D = Urge Incontinence E = Urgency and Urge Incontinence F = Frequency and Urge Incontinence G = Frequency, Urgency and Urge Incontinence

11. Age-specific respondents with OAB

12. OAB as a Problem Degree of BotherDegree of Bother –Scoring from 0 to 5 0 – no bother, 5 – severe Need for Leakage Protection in urge incontinenceNeed for Leakage Protection in urge incontinence Seeking HelpSeeking Help

13. Degree of bother in patients with OAB

14. OAB as a Problem: Rate of Seeking Help

15. Age more than 70 years = 2.808 Professional labor = 1.117 Sitting type toilet = 1.070 Urban dwelling = 1.306 Chances of OAB (odds ratio)

16. Demographic Factors Associated with a Higher Prevalence of OAB Older ageOlder age ProfessionalsProfessionals Positive family history for voiding dysfunction (19% of respondents in this study)Positive family history for voiding dysfunction (19% of respondents in this study) Use of a sitting toiletUse of a sitting toilet Higher incomeHigher income Urban dwellingUrban dwelling

17. Constitutional factors of OAB Obesity, White race, Increasing age Behavioural Risk factors Consumption of caffeine, alcohol, tobacco, low daily physical activity Neurological Risk factors Stroke, Paraplegia, Paralysis, Immobility and cognitive impairment
