Abstract: 25-Hydroxyvitamin D-3 (25(OH)D-3) as the metabolite of vitamin D, is connected with various of diseases, and important to people with limited sunshine. Thus, the investigation of serum 25-hydroxyvitamin D and its variation in these people is necessary. In this study, a simple, precise, and accurate method for serum 25(OH)D-3 determination by LC/MS/MS was developed. Serum samples were obtained monthly for one year from 11 male and 11 female indoor workers in Sapporo, Japan, and the overall 25(OH)D-3 concentration was 12.9 +/- 4.7 ng/mL. The 25(OH)D-3 in females was significantly lower than that in males (14.0 +/- 5.0 vs. 11.9 +/- 4.3 ng/mL). The serum 25(OH)D-3 concentration in males and females were both strongly correlated to UV-B radiation (r(2) = 0.8477 and 0.7384, respectively), with a two-month's lag. Also the monthly change in 25(OH)D-3 in males was more significant than that in females.
