The lowSe exposed group was divided into three subgroups, such as Se content in hair110 ng/g, 110 ng/g<Se content in hair150 ng/g and 150 ng/g<Se content in hair200 ng/g, respectively. Six new cases of the total with KBD (incidence was 0574% personyear) were found in the lowSe exposed group during three years period of the investigation. No new case was found in the non lowSe exposed group . KBD incidence was not significantly different between those two groups. Two new cases were found in children with Se content in hair kept below 110 ng/g during three years (incidence: 121% personyear). SMR in each group indicated that the new cases observed in the lowSe exposed group was remarkable lower than the new cases expected.
