The number of research subjects was 5888.

Women had higher prevalence than men (P < 0.01). The prevalence of MS increased with age. Abrupt increase of the prevalence started at age of 50 in women. The prevalence varied by education, marital status, occupation and income. People from the urban and the south had a higher prevalence than from the rural and from the northern part of the country.
