To measure health-related quality of life (HRQOL) of elementary and secondary school students in rural China using the simplified Chinese version of the EQ-5D-Y.
Both the samples of students were from a school-based cohort study in a county located in southwestern China. The students self-completed the EQ-5D-Y. Feasibility was evaluated according to the percentages of missing values. Known group validity was assessed by comparing the frequency of reporting EQ-5D-Y problems between groups known to differ in health status.
A total of 1728 elementary students and 2116 secondary students were included in the analysis. Their respective mean age was 8.7 (range: 7-15) years and 14.8 (range: 11-18) years, with girls being 45.1 and 50.1%, respectively. The missing values in both samples were quite low. Elementary students were less likely to have problems on'having pain or discomfort' and 'feeling worried, sad or unhappy' dimensions, but more likely to report problems on the dimensions related to physical functioning. Gender difference in HRQOL was only detected for secondary students in terms of 'doing usual activities', 'having pain or discomfort,' and 'feeling worried, sad or unhappy' (P < 0.05 for all). The significant differences in HRQOL were not observed for the other characteristics.
It appears that the EQ-5D-Y is feasible and valid instrument in school-aged children and adolescents in rural China; but it suffers from similar disadvantages to those found in other general populations. The HRQOL distributions measured by the EQ-5D-Y were also provided.
使用简化中文版 EQ-5D-Y 测量中国农村中小学生的健康相关生活质量（HRQOL）。
学生样本均来自中国西南部某县的一项基于学校的队列研究。学生自行填写 EQ-5D-Y。根据缺失值的百分比评估可行性。通过比较已知健康状况不同的组之间报告 EQ-5D-Y 问题的频率来评估已知组有效性。
共纳入 1728 名小学生和 2116 名中学生进行分析。他们的平均年龄分别为 8.7（范围：7-15）岁和 14.8（范围：11-18）岁，女生分别为 45.1%和 50.1%。两个样本的缺失值都相当低。小学生在“有疼痛或不适”和“感到担忧、悲伤或不开心”维度上不太可能出现问题，但更有可能报告与身体功能相关的维度上出现问题。仅在“进行日常活动”、“有疼痛或不适”和“感到担忧、悲伤或不开心”这三个维度上，中学生的 HRQOL 存在性别差异（所有 P 值均<0.05）。其他特征未观察到 HRQOL 的显著差异。
简化中文版 EQ-5D-Y 在中国农村学龄儿童和青少年中似乎是一种可行且有效的工具；但它存在与其他一般人群相同的劣势。还提供了 EQ-5D-Y 测量的 HRQOL 分布。
