Abstract

Objective: To investigate the levels of serum 25-hydroxy vitamin D(25-OHD) and its related influence factors in the adults in Qujing area of Yunnan Province in China.

Method: 25-OHD levels in the sera were detected with a 25-hydroxy vitamin D kit and read with LIAISON XL chemiluminescence analyzer. Data was statistically analyzed with software SPSS17.0.

Results: The serum 25-OHD levels of the subjects were 12.08 ± 5.92 ng/ml. Although the sera levels of 25-OHD were significantly higher in urban residents, men and young subjects than in rural residents, women, and old subjects, the 25-OHD levels were significantly lower compared to international standard values in almost all populations in Qujing area.

Conclusion: Qujing is plateau area with affluent sunlight, however, serum 25-OHD levels of majority populations are low. The serum 25-OHD levels are affected by many factors. In order to avoid excessive diagnosis and treatment, the adjusted local standard values of serum 25-OHD are needed.

Keywords: Adult; epidemic; serum 25-hydroxy vitamin D.
