Health burden associated with unhealthy lifestyle behaviors in the general Chinese population

This study estimated and compared the loss in quality-adjusted life years (QALYs) associated with common unhealthy lifestyle behaviors in the general Chinese population. A large-scale cross-sectional study was conducted using a self-report questionnaire among 21,909 Chinese residents (aged 12 years or older). We identified seven unhealthy lifestyle behaviors including drinking, smoking, sugar-sweetened beverage intake, breakfast skipping, prolonged sitting time, insufficient sleep duration, and poor sleep quality. In this survey, health utility of the participants was derived using the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L). Regression models were used to analyze the effects of each unhealthy lifestyle behavior on health utility. The annual QALY loss per 100,000 persons was calculated for each condition, incorporating behavior prevalence and health utility data. Among the seven behaviors, insufficient sleep duration (64.6
