An epidemiological study of erectile dysfunction in Thailand (Part 1: Prevalence). Thai Erectile Dysfunction Epidemiologic Study Group (TEDES).

The Epidemiological Study of Erectile dysfunction in Thailand empirically investigates erectile dysfunction (ED) in Thailand. This article is part of this study with the major aim of estimating prevalence in the country. A nationwide representative sample of 1,250 urban Thai men aged between 40 and 70 years were studied. The estimation of overall prevalence of ED among the respondents living in urban areas was 37.5 per cent. This proportion consisted of 19.1 per cent of males with mild dysfunction, while about 13.7 per cent and 4.7 per cent of the samples had moderate and severe dysfunction. Of all four regions together with Bangkok Metropolis, the latter had the lowest prevalence while the North had the highest level. In addition, the prevalence estimation for smaller provinces was 36.4 per cent and 46.4 per cent for larger provinces. Moreover, results of this study indicated that when men become older, they have a greater likelihood of suffering from ED and the prevalence rate of ED rapidly increased from age group 40-49 years to 60-70 years.
