摘要
目的 了解陕西省彬县大骨节病病区成人及学龄儿童硒营养现状,为采取针对性措施提供依据。方法 2018年,依据大骨节病病情将彬县划分为5个病区等级,选择11个有代表性病区村作为调查村,每个调查村划分为东、西、南、北、中5个方位,每个方位选择2户村民,采集成人发样,进行发硒含量测定。在5个病区等级对应的乡镇小学及1个村小学,采集学龄儿童发样,进行发硒含量测定。结果 共采集成人发样85份,发硒含量均值为231.7 μg/kg,总体处于边缘硒缺乏水平(200 ~ < 250 μg/kg),不同病区等级间成人发硒含量比较差异无统计学意义(χ2 = 5.616,P > 0.05);共采集儿童发样162份,发硒含量均值为301.3 μg/kg,总体处于中等硒营养水平(250 ~ < 500 μg/kg),不同病区等级儿童发硒含量比较差异有统计学意义(χ2 = 13.627,P < 0.05)。结论 彬县虽从整体上摆脱了大骨节病风险,但是部分成人及儿童硒营养水平仍较低,需加强防控,尤其是针对生活在历史病情相对较重的病区村的学龄儿童。
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 237.1μg/kg,generally at the marginal selenium deficiency level(200-<250μg/kg),and there was no significant difference among different grades of disease areas(χ2=5.616,P>0.05).A total of 162 children hair samples were collected,the average selenium content was 301.3μg/kg,generally at the middle selenium nutrition level(250-<500μg/kg),and there was significant difference among different grades of disease areas(χ2=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.
