简要总结
This study aims to explore the effectiveness of a combined intervention using brief cessation advice and personalized chat-based positive psychological support compared with the control group on current smokers who join the Quit to Win Contest.
详细描述
Smoking is a leading cause of many diseases and deaths globally. Although Hong Kong has a relatively low overall smoking rate of 10.2% (in 2019), health and economic burdens due to smoking are still substantial. The practice of smoking might predispose smokers to COVID-19 infection and poor prognosis. Growing evidence has also suggested that smokers are at higher risk of developing serious respiratory and cardiovascular symptoms in the COVID-19 pandemic than non-smokers. Smoking cessation in the post-COVID-19 era is the key priority to meet the HKSAR Government's target of reducing smoking prevalence to 7.8% by 2025.
Mental health problems are commonly comorbid with smoking and related problems. Our population-based survey amidst the COVID-19 pandemic found current smokers were at higher risk of suffering from anxious symptoms (adjusted OR 1.84 95% CI 1.27, 2.67), depressive symptoms (adjusted OR 2.04 95% CI 1.40, 2.96), and stress symptoms (adjusted β 0.54 95% CI 0.26, 0.82) compared with non-smokers. We also observed mental health burden increased during the COVID-19 pandemic with approximately doubling of the prevalence of anxious symptoms (15.8 vs. 9.3) and depressive symptoms (14.8 vs. 6.3) compared with the pre-COVID-19 pandemic (2017). Mental health can be both precursors and consequences of smoking. Previous studies have suggested that depressive symptoms and low positive affect during and after SC attempts are associated with poor cessation outcomes. This implies that a combined intervention of behavioral and psychological SC intervention is needed, particularly under the circumstance of worsening mental health problems.
Therefore, our study aims to test the effectiveness of a combined intervention using brief cessation advice and personalized chat-based positive psychological support compared with the control group on current smokers who join the Quit to Win Contest.

主要结局
Biochemically validated abstinence
时间窗: 6-month follow-up
Defined as exhaled CO level \<4ppm and saliva cotinine level ≤30 ng/ml Note 1. If participants refuse to have a face-to-face exhaled carbon monoxide test due to the COVID-19 pandemic in Hong Kong. In that case, the outcome will only be validated by a saliva cotinine test device. 2. If participants use NRT, the outcome will be validated by exhaled carbon monoxide only.
