  1. Prevalence of OAB in Asian Men: an epidemiological survey P Moorthy, et al British Journal of Urology: 93: 528-531, 2004

  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 males • Determine the status of OAB as a problem • Determine the demographic factors related to the occurrence of OAB • Determine the degree of bother and treatment seeking rate in Asian men

  4. Methodology • Questionnaire 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. TOTAL: Males : 2369 Participating countries Philippines China Indonesia Malaysia Singapore Thailand Hong Kong Taiwan Korea India Pakistan Survey Population

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

  7. Definitions • 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

  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 Bother • Scoring from 0 to 5 0 – no bother, 5 – severe • Need for Leakage Protection in urge incontinence • Seeking Help

  13. Degree of bother in patients with OAB

  14. OAB as a Problem: Rate of Seeking Help

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

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