Utility scores are an important tool for evaluating health-related quality of life. Utility score norms have been published for Canadian adults, but no nationally representative utility score norms are available for children and youth.
Health Utilities Index Mark 3 (HUI3) data from two recent cycles of the Canadian Health Measures Survey (i.e., 2016 and 2017, and 2018 and 2019) were used to provide utility score norms for children aged 6 to 11 years and adolescents aged 12 to 17 years. Children younger than 14 years answered the HUI3 under the supervision of an adult, while older children answered without supervision. Utility scores were reported as a weighted average (95% confidence intervals [CIs]) and median values (interquartile range). Utility scores were stratified by sociodemographic and medical characteristics of the child or adolescent. Regression analyses were used to identify predictors of utility scores. All results were weighted using sampling weights provided by Statistics Canada.
Among the 2,297,136 children aged 6 to 11 years and the 2,329,185 adolescents aged 12 to 17 years in the weighted sample, the average utility scores were 0.95 (95% CI: 0.94 to 0.95) and 0.89 (95% CI: 0.87 to 0.90), respectively. Approximately 60% of the children and 34% of the adolescents had a utility score of 1.00. Analyses identified several factors associated with utility scores (e.g., age, chronic condition and income levels), although differences were observed between children and adolescents.
This study provides utility score estimates based on a nationally representative sample of Canadian children and youth. Further research examining the determinants of utility scores of children and adolescents is warranted.
效用评分是评估健康相关生活质量的重要工具。已发布加拿大成年人的效用评分标准，但尚无针对儿童和青少年的全国代表性效用评分标准。
使用来自加拿大健康测量调查（即 2016 年和 2017 年以及 2018 年和 2019 年）的两个最近周期的健康效用指数标记 3（HUI3）数据，为 6 至 11 岁的儿童和 12 至 17 岁的青少年提供效用评分标准。14 岁以下的儿童在成人的监督下回答 HUI3，而年龄较大的儿童则在无人监督的情况下回答问题。效用评分报告为加权平均值（95%置信区间[CI]）和中位数（四分位间距）。根据儿童或青少年的社会人口统计学和医疗特征对效用评分进行分层。使用加拿大统计局提供的抽样权重进行回归分析以确定效用评分的预测因素。所有结果均使用加权。
在加权样本中，2297136 名 6 至 11 岁的儿童和 2329185 名 12 至 17 岁的青少年中，平均效用评分为 0.95（95%CI：0.94 至 0.95）和 0.89（95%CI：0.87 至 0.90），分别。大约 60%的儿童和 34%的青少年的效用评分为 1.00。分析确定了与效用评分相关的几个因素（例如年龄、慢性疾病和收入水平），尽管在儿童和青少年之间观察到差异。
本研究提供了基于加拿大儿童和青少年全国代表性样本的效用评分估计。进一步研究儿童和青少年效用评分的决定因素是必要的。
