To examine the comparative performance of EuroQol EQ-5D-5L and Center for Disease Control Healthy Days measures in assessing population health.
Using data from 2014 Alberta Community Health Survey, a cross-sectional population-based survey (N = 7559), conducted in Alberta, Canada, we examined construct validity of the measures as indicators of population health. Differences in EQ-5D-5L index score, visual analogue scale (EQ-VAS), and CDC unhealthy days index across socio-demographic subgroups were tested by Mann-Whitney and Kruskal-Wallis tests using known-groups approach.
EQ-5D-5L and CDC Healthy Days provided comparable assessments of population health in this sample. Both measures discriminated between subgroups defined by self-perceived health status, level of education, and material deprivation. The discriminative ability of CDC Healthy Days was limited in capturing variability in health among age groups compared to the EQ-5D-5L. Among participants who reported 0 unhealthy days, the proportion of those with level 3 problems in pain/discomfort varied from 1.1% for participants aged 18-24 to 19.2% for those over 75 years.
EQ-5D-5L demonstrated better construct validity than CDC Healthy Days in assessing health in a population-based sample of adults.
考察欧洲五维度健康量表（EuroQol EQ - 5D - 5L）和美国疾病控制与预防中心健康日指标在评估人群健康方面的比较表现。
利用2014年艾伯塔社区健康调查的数据，这是一项在加拿大艾伯塔省开展的基于人群的横断面调查（N = 7559），我们检验了这些指标作为人群健康指标的结构效度。采用已知组方法，通过曼 - 惠特尼检验和克鲁斯卡尔 - 沃利斯检验，对社会人口学亚组间的EQ - 5D - 5L指数得分、视觉模拟量表（EQ - VAS）以及美国疾病控制与预防中心不健康日指数的差异进行了检验。
在本样本中，EQ - 5D - 5L和美国疾病控制与预防中心健康日指标对人群健康的评估结果相当。这两种指标在由自我感知健康状况、教育水平和物质匮乏程度所定义的亚组之间都具有区分能力。与EQ - 5D - 5L相比，美国疾病控制与预防中心健康日指标在捕捉不同年龄组健康差异方面的区分能力有限。在报告0个不健康日的参与者中，疼痛/不适程度为3级问题的参与者比例在18 - 24岁的参与者中为1.1%，在75岁以上的参与者中为19.2%。
在基于人群的成人样本中评估健康状况时，EQ - 5D - 5L的结构效度优于美国疾病控制与预防中心健康日指标。
