Males' prevalence was of 84.08%, comparatively with females (15.91% from total cases). Difference between residence areas had not statistic significance. In Iasi County, AS prevalence had increased values in all 17 years of study period, greater and often double that those at national level, and also greater than every county from Moldavia and one from the Western Romania. Demographical structure, variations, and those occupational, ecological, economical, educational could explain this situation.
