The focus of this study is to determine the relationship between selenium (Se) concentrations in child hair and the distribution of Kashin-Beck disease (KBD) in Tibet. The hair of children in typical KBD-affected areas and non-disease areas was collected, and its Se concentrations were measured by atomic fluorescent spectrometry. The Se concentrations in child hair were (0.13±0.04) and (0.18±0.07) μg/g respectively in KBD areas and non-disease areas respectively, which are significantly different. In areas supplemented with Se in Tibet, the Se concentration of hair in KBD-affected areas was higher than that in non-diseased areas, being (0.28±0.03) and (0.18±0.04) μg/g respectively. There is a close relationship between the Se concentrations in hair and KBD distribution. Se supplement increase the Se concentrations in the human body. Appropriate Se supplementation is important to prevent KBD in Tibet.
本研究的重点是确定西藏儿童头发中硒（Se）浓度与大骨节病（KBD）分布之间的关系。收集了典型大骨节病病区和非病区儿童的头发，采用原子荧光光谱法测定其硒浓度。大骨节病病区和非病区儿童头发中的硒浓度分别为（0.13±0.04）μg/g和（0.18±0.07）μg/g，差异有统计学意义。在西藏补硒地区，大骨节病病区头发中的硒浓度高于非病区，分别为（0.28±0.03）μg/g和（0.18±0.04）μg/g。头发中的硒浓度与大骨节病分布密切相关。补硒可提高人体中的硒浓度。适当补硒对预防西藏大骨节病很重要。
