简要总结
Smoking causes cardiovascular and respiratory diseases, cancers and diabetes, and it has been a leading risk factor for death globally. Despite the availability of smoking cessation services locally, most smokers do not use such services. Workplace is one of the most convenient platforms to provide smoking cessation services and over 55% of smokers are employed according to the local population-based survey. Moreover, The COVID-19 pandemic and new normal increase in mental health burden to people in the workplace. An online survey during the pandemic found 88% of Hong Kong employees suffered from stress at work during the past 7 days. Mental health can be both precursors and consequences of smoking. However, the effectiveness of a smoking cessation programme conducted in workplace is yet to be examined in Hong Kong, and the mental health support for smoking employees in promoting smoking cessation is not clear. Thus, this study aims to test, by a 2-arm RCT, the effectiveness of an intervention of which includes mobile phone-based intervention on reducing mental health symptoms and smoking cessation in workplaces in Hong Kong; identify facilitators and barriers of successful policy implementation and quitting; examine and evaluate the company environment and their policies in promoting smoking cessation.
