Abstract:
Objective:To assess the present situation of selenium nutrition in adults and school-age children in Kaschin-Beck disease area of Binxian, Shaanxi Province, and provide the basis for taking targeted measures.Methods:Binxian was divided into five grades according to the condition of Kaschin-Beck disease, and 11 representative villages were selected as the survey villages in 2018. Each survey village was located in five directions: east, west, south, north, and middle. Two household villagers were selected from each location, and adult hair samples were collected for hair selenium content determination. And school-age children hair samples were collected at the township central primary schools and 1 village primary school corresponding to the five ward levels, and the selenium content was determined.Results:A total of 85 adult hair samples were collected, the average selenium content was 237.1 μg/kg, generally at the marginal selenium deficiency level (200 - < 250 μg/kg), and there was no significant difference among different grades of disease areas (χ 2 = 5.616, P > 0.05) . A total of 162 children hair samples were collected, the average selenium content was 301.3 μg/kg, generally at the middle selenium nutrition level (250 - < 500 μg/kg), and there was significant difference among different grades of disease areas (χ 2 = 13.627, P < 0.05) . Conclusion:Although Binxian has got rid of the risk of Kaschin-Beck disease as a whole, the selenium nutrition levels of some adults and children are still low, so it is still necessary to strengthen the prevention and control measures, especially for school-age children living in a relatively serious historical disease villages.
