To revisit the population norms of health-related quality of life (HRQoL) and health utility for the Hong Kong general population, compare these scores over past health surveys, and assess the association of scores with non-communicable diseases (NCDs) and their risk factors.
HRQoL data measured by the standard Short Form 12 Health Survey-version 2 (SF-12v2) were extracted from the surveys in 1998, 2003/2004, 2008/2009 and 2014/2015. SF-12v2 data were mapped to the Short-form 6-dimension (SF-6D) preference-based measure to generate the health utility scores. Population weighting based on the sex and age in the second quarter of 2015 was applied when generating population normative values. Linear regression models were fitted to assess the effect of the number of NCDs and modifiable lifestyle factors on HRQoL and health utility.
The general population mean scores of SF-12v2 domains and SF-6D in 2014/15 were higher compared to past surveys. Linear increases in General Health, Vitality and Mental Health domains were observed from 1998 to 2014/15. More doctor-diagnosed NCDs, insufficient physical activity and fruit/vegetable consumption, poor sleep quality and insufficient or excessive amount of sleep (< 6/≥ 10 h) were all associated with worse physical- and mental-related HRQoL and health utility.
This study compared HRQoL and health utility in the Hong Kong general population derived from multiple surveys and found an improving trend over twenty years. More NCDs were associated with worse HRQoL. It is suggested that promoting adequate physical activity, consumption of fruit/vegetable and 6-9 h of sleep could improve health.
重新审视香港普通人群健康相关生活质量（HRQoL）和健康效用的人口正常值，比较过去健康调查中的这些分数，并评估分数与非传染性疾病（NCDs）及其危险因素的相关性。
从 1998 年、2003/2004 年、2008/2009 年和 2014/2015 年的调查中提取了使用标准 12 项简短健康调查量表第二版（SF-12v2）测量的 HRQoL 数据。SF-12v2 数据被映射到短期 6 维度（SF-6D）偏好测量，以生成健康效用评分。在生成人口正常值时，应用了基于 2015 年第二季度性别和年龄的人口加权。拟合线性回归模型评估 NCD 数量和可改变的生活方式因素对 HRQoL 和健康效用的影响。
2014/15 年普通人群 SF-12v2 域和 SF-6D 的平均得分高于过去的调查。从 1998 年到 2014/15 年，一般健康、活力和心理健康领域的得分呈线性增加。更多的医生诊断的 NCDs、体力活动不足、水果/蔬菜摄入不足、睡眠质量差以及睡眠不足或过多（<6/≥10 小时）均与较差的身体和心理健康相关的 HRQoL 和健康效用相关。
本研究比较了来自多项调查的香港普通人群的 HRQoL 和健康效用，并发现二十年来呈上升趋势。更多的 NCDs 与较差的 HRQoL 相关。建议促进足够的体力活动、水果/蔬菜的摄入以及 6-9 小时的睡眠可以改善健康。
