The positive rate of 35 allergens were examined using the MAST system for 7 cities in Japan consisting of: Sapporo, Tokyo, Nara, Wakayama, Osaka, Kobe, and Oita. The subjects included 100 healthy adults from each city made up of 50 males and 50 females whose ages ranged from 20 to 29 years. Dermatophagoides pteronyssinus and D. farinae were the main allergens found in all cities and the positive rate was 33%. The Japanese cedar allergen came in second with 14%. On the other hand, the rates were low for all food allergens. The positive rate for the Japanese cedar allergen was highest of the 10 pollens investigated in all cities except Sapporo. Overall, the positive rates of the male group tended to exceed those of the female group for each allergen. As mentioned above, the positive rates were therefore influenced by several factors including sex, area and population.
