The dose-response relationship between total cadmium intake and beta 2-microglobulinuria was investigated using logistic regression analysis in order to consider the effect of age on this association. The target population consisted of 1850 inhabitants of the cadmium-polluted Kakehashi River basin in Ishikawa prefecture, Japan. They were divided into 58 subgroups (27 in the men and 31 in the women) by four factors of sex, age, rice cadmium concentration and length of residence in cadmium-polluted areas. Logistic regression analysis was performed for this dose-response relationship, and both age and total cadmium intake were significantly associated with beta 2-microglobulinuria. It was confirmed that total cadmium intake had a significant association with beta 2-microglobulinuria, independent of the aging effect.
