The purpose of this study was to investigate the association between smoking and health-related quality of life among Chinese individuals aged 40 years and older.
Using a stratified multistage sampling method, data from 1,543 adults aged 40 years and older were obtained from a household survey conducted in eight provinces in China. The health-related quality of life was quantified based on the utility index obtained using a standardized instrument entitled "The European Five-Dimensional Health Scale (EQ-5D-5L)." Descriptive statistics were used to summarize the demographic characteristics and social factors of the sample according to smoking status. An instrumental variable (IV) probit model was used to estimate the association between smoking status and health-related quality of life.
Of the 1,543 participants, 485 (31.43%) were smokers and 1,058 (68.57%) were non-smokers. Smoking was negatively associated with the probability of having a higher quality of life ( < 0.01). For smokers, the average probability of having a higher quality of life was 11.65% lower than when they did not smoke.
These findings suggest that smoking reduces health-related quality of life among Chinese individuals aged 40 years and older. Anti-smoking programs should consider this factor.
本研究旨在探讨中国 40 岁及以上人群吸烟与健康相关生活质量之间的关系。
采用分层多阶段抽样方法，从中国 8 个省份的家庭调查中获得了 1543 名 40 岁及以上成年人的数据。健康相关生活质量根据使用标准化工具“欧洲五维健康量表（EQ-5D-5L）”获得的效用指数进行量化。根据吸烟状况，采用描述性统计方法总结样本的人口统计学特征和社会因素。采用工具变量（IV）概率模型估计吸烟状况与健康相关生活质量之间的关联。
在 1543 名参与者中，485 名（31.43%）为吸烟者，1058 名（68.57%）为非吸烟者。吸烟与更高生活质量的可能性呈负相关（<0.01）。对于吸烟者，拥有更高生活质量的平均概率比不吸烟时低 11.65%。
这些发现表明，吸烟会降低中国 40 岁及以上人群的健康相关生活质量。戒烟计划应考虑这一因素。
