To explore the association of academic performance and general health status with health-related quality of life (HRQoL) in school-aged children and adolescents in China.
In this cross-sectional study conducted in 2018, students (grade 4-12) were randomly chosen from primary and high schools in Nanjing, China. HRQoL, the outcome measure, was recorded using the Child Health Utility 9D, while self-rated academic performance and general health were the independent variables. Mixed-effects regression models were applied to compute mean difference (MD) and 95% confidence interval (CI) of HRQoL utility score between students with different levels of academic performance and general health.
Totally, 4388 participants completed the study, with a response rate of 97.6%. The mean HRQoL utility score was 0.78 (SD: 0.17). After adjustment for socio-demographic attributes, physical activity, sedentary behavior, dietary patterns, body weight status and class-level clustering effects, students with fair (MD = 0.048, 95% CI 0.019, 0.078) and good (MD = 0.082, 95% CI 0.053, 0.112) self-rated academic performance reported higher HRQoL utility scores than those with poor academic performance, respectively. Meanwhile, students with fair (MD = 0.119, 95% CI 0.083, 0.154) and good (MD = 0.183, 95% CI 0.148, 0.218) self-assessed general health also recorded higher HRQoL utility scores than those with poor health, separately. Consistent findings were observed for participants by gender, school type and residential location.
Both self-rated academic performance and general health status were positively associated with HRQoL among Chinese students, and such relationships were independent of lifestyle-related behaviors and body weight status.
探讨中国学龄儿童和青少年的学业成绩和一般健康状况与健康相关生活质量（HRQoL）之间的关系。
本横断面研究于 2018 年在中国南京市的小学和中学进行，随机选择 4 至 12 年级的学生。使用儿童健康效用 9D 量表记录 HRQoL 作为结局指标，自我报告的学业成绩和一般健康状况为自变量。采用混合效应回归模型计算不同学业成绩和一般健康状况学生的 HRQoL 效用评分的平均差异（MD）和 95%置信区间（CI）。
共有 4388 名学生完成了研究，应答率为 97.6%。HRQoL 效用评分的平均得分为 0.78（SD：0.17）。在调整社会人口统计学特征、体力活动、久坐行为、饮食模式、体重状况和班级水平聚类效应后，自我报告学业成绩为“一般”（MD=0.048，95%CI 0.019，0.078）和“良好”（MD=0.082，95%CI 0.053，0.112）的学生报告的 HRQoL 效用评分高于学业成绩差的学生。同时，自我评估健康状况为“一般”（MD=0.119，95%CI 0.083，0.154）和“良好”（MD=0.183，95%CI 0.148，0.218）的学生也记录了更高的 HRQoL 效用评分，优于健康状况差的学生。在按性别、学校类型和居住地点分层的参与者中观察到一致的发现。
自我报告的学业成绩和一般健康状况与中国学生的 HRQoL 呈正相关，且这种关系独立于与生活方式相关的行为和体重状况。
