RESUMO
OBJECTIVE: The aim of this study is to investigate changes in sexual activity and the prevalence of erectile dysfunction (ED) in Thai males. In addition, the treatment-seeking behaviour of Thai patients suffering from ED is also investigated. MATERIALS AND METHODS: In a cross sectional study using a standardized questionnaire with a multi-stage stratified random sampling, 2,269 men aged 40-70 were interviewed. The questionnaire was designed to investigate the effects of socioeconomic factors, medical conditions and unhealthy lifestyles on the development of ED. Furthermore, the questionnaire was designed to characterize the treatment-seeking behaviour of Thai patients suffering from ED. RESULTS: Compared to the first report dated the year 2000, the prevalence of ED has increased from 37.5% to 42.18%. In terms of socioeconomic factors, the highest prevalence of ED was observed among unemployed men (78.51%). Prostatism and/or prostatitis (Odd ratios (OR) = 2.02) and long histories of smoking (more than 30 years, OR = 2.36) were identified as statistically significant risk factors for ED, with p-values of <0.001. It is important to notice that 38.78% of the ED patients wanted to discuss their problem with spouses or partners. Three quarters of the ED patients (74.54%) preferred oral medication as therapy. CONCLUSIONS: The epidemiology of ED in Thailand is changing. An increased prevalence of ED does require further epidemiological studies on a regular basis in order to better understand the etiology of ED and look for measures (such as education) to counter the disease.
