Brief Summary:

The aim of this project is to promote and evaluate a smoking cessation intervention through the "Quit to Win" Contest organised in correctional institutions in Hong Kong.

The aim of this project is to promote and evaluate a smoking cessation intervention through the "Quit to Win" Contest organised in correctional institutions in Hong Kong. The specific objectives of the study are:

  1. To test the effectiveness of face-to-face brief cessation advice (AWARD) and video education for smoking cessation among current smokers at the correctional institutions in Hong Kong;
  2. To evaluate the process and outcome of the recruitment of smokers through qualitative interviews; and
  3. To conduct qualitative interviews with quitters and non-quitters to examine their experience on the intervention.

Condition or disease Intervention/treatment Phase
Smoking Cessation Behavioral: AWARD advice Behavioral: Video-based health education Not Applicable

Detailed Description:

Although smoking prevalence is decreasing in Hong Kong, there are still 615,000 daily cigarette smokers in Hong Kong in 2017 and half will be killed by smoking [5] which accounts for over 7,000 deaths per year. Smoking is a highly addictive behavior and it is difficult for smokers with strong nicotine dependence to quit without assistance. Despite the low smoking rate in the general population, smoking prevalence remain high in the correctional institutions. Incarcerated prisoners suffer disproportionately from mental illness, substance use disorders and disease infections. They are in need of health care such as treatment or prevention for smoking. There is a lack of evidence on the effectiveness of smoking cessation intervention in the correctional setting. More work is required to provide smoking cessation assistance to these high risk and underserved population.

The aim of this project is to promote and evaluate a smoking cessation intervention through the "Quit to Win" Contest organised in correctional institutions in Hong Kong. The specific objectives of the study are:

  1. To test the effectiveness of face-to-face brief cessation advice (AWARD) and video education for smoking cessation among current smokers at the correctional institutions in Hong Kong;
  2. To evaluate the process and outcome of the recruitment of smokers through qualitative interviews; and
  3. To conduct qualitative interviews with quitters and non-quitters to examine their experience on the intervention.

Arm Intervention/treatment
Experimental: Group A

CSD participants will receive a combined intervention:

  1. Brief intervention using AWARD advice at baseline,
  2. Video-based health education
Behavioral: AWARD advice
Ask about smoking history, Warn about the high risk of smoking, Advise to quit as soon as possible, Refer to the smoking cessation services, and Do it again (if the smokers refused to set quit date)

Behavioral: Video-based health education
Educational videos on smoking and health will be developed to improve the knowledge of CSD smokers. Smoking cessation counselor from the School of Nursing will conduct health talks. CSD will provide venue for viewing the video and health promotion talks. Health talks (n=4) will be provided by small group format. This health talk aims to raise their awareness on these important health topics and acquire effective cessation methods. The effectiveness of the educational videos will be evaluated by pre- and post-tests through a self-administered survey that assess the changes in knowledge related to smoking hazards, benefits of quitting, and methods to quit smoking.




Primary Outcome Measures :
  1. Biochemical validated quit rate at 6-month follow-up [ Time Frame: 6-month follow-up ]
    The primary outcome is biochemically validated quit rates (exhaled CO < 4 ppm and salivary cotinine < 10 ng/ml) at 6-month

  2. Biochemical validated quit rate at 3-month follow-up [ Time Frame: 3-month follow-up ]
    The primary outcome is biochemically validated quit rates (exhaled CO < 4 ppm and salivary cotinine < 10 ng/ml) at 3-month


Secondary Outcome Measures :
  1. Smoking quit rate change from baseline at 3-month follow-up [ Time Frame: 3-month follow-up ]
    Self-reported 7-day point prevalence (pp) quit rate at 3-month

  2. Smoking quit rate change from baseline at 6-month follow-up [ Time Frame: 6-month follow-up ]
    Self-reported 7-day point prevalence (pp) quit rate at 6-month

  3. Smoking reduction rate change from baseline at 3-month follow-up [ Time Frame: 3-month follow-up ]
    Rate of smoking reduction by at least half of baseline amount

  4. Smoking reduction rate change from baseline at 6-month follow-up [ Time Frame: 6-month follow-up ]
    Rate of smoking reduction by at least half of baseline amount
