青藏高原大骨节病流行区环境-人体硒含量数据集（2000-2018）

该数据集包含了青藏高原大骨节病流行区土壤、饮用水和主要粮食（青稞、糌粑、小麦、大米等）环境及人发中的硒元素平均含量。数据主要来源于2000-2018 年发表的所有相关中英文文献，依据严格的文献筛选标准和业内专家质量评价予以收集，部分来源于样品自测数据，对同一地区(县或区)不同年份的监测值采用样本量与样本硒平均含量的加权平均值进行整合。该数据集涉及青藏高原地区39个大骨节病病县，基本覆盖了各病区的主要区域，有效样本量大于7000个，能够反映青藏高原大骨节病流行区现阶段硒的平均水平，数据可为青藏高原地区地方病防控以及硒与其他相关疾病关系的研究提供数据基础。This dataset contains the average selenium concentrations in soil, drinking water, staple foods including highland barley (qingke), zanba, wheat, rice, and other major crops, as well as human hair from the Kashin-Beck Disease (KBD) endemic areas on the Qinghai-Tibet Plateau. The data were primarily sourced from all relevant English and Chinese literatures published between 2000 and 2018, curated following strict literature screening criteria and quality evaluations by domain experts. Part of the dataset originates from self-measured laboratory samples. For monitoring values from the same region (county or district) across different years, a weighted average based on both the sample size and the average selenium concentration of each sample group was used to consolidate the data. This dataset covers 39 KBD-endemic counties on the Qinghai-Tibet Plateau, broadly covering the core areas of all endemic regions. The effective sample size exceeds 7,000, which can accurately reflect the current average selenium level in the KBD endemic areas of the Qinghai-Tibet Plateau. This dataset can serve as a foundational data resource for endemic disease prevention and control on the Qinghai-Tibet Plateau, as well as studies exploring the association between selenium and other related diseases.
