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.
