About this study

The objectives of this policy-related survey are as follows:

  1. to study updated trend and prevalence on secondhand smoke, smoking-attributed health effects, cessation services; ii. to investigate the level of public support on current and future tobacco control measures and taxation policies; iii. to address the timely impacts of smoke-free policies, substantiate public support on further tobacco control measures and assist Hong Kong Council On Smoking and Health (COSH) in shaping policy direction for government.

Purpose of the study is to provide evidence and support for smoke-free policy development in Hong Kong.

Read the detailed description

Smoking is a major cause of premature death. Each year, tobacco kills nearly 6 million people globally, including more than 600,000 non-smokers by secondhand smoke (SHS). During the past few decades, tobacco control has contributed prominently to international health, and the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), the first international health treaty negotiated by WHO has propelled tobacco control into a new era. In order to determine the impact of and opinions on tobacco control policies, many countries around the world have carried out surveys on policies either implemented or under consideration. A number of surveys have assessed the impact of policies such as smoke-free laws, including the National Health and Nutrition Examination Survey (NHANES), the International Tobacco Control (lTC) Surveys and the Global Adult Tobacco Survey (GATS).

In 2013 and 2014, the investigators conducted two waves of the policy-related survey on tobacco control. The surveys gathered information such as SHS exposure at home, in the workplace, and in various public places (e.g. bars/restaurants, door way of the buildings, streets, and bus stops), use of smoking cessation services, knowledge of smoking and quitting, and smoking prevalence; measured the impact of tobacco control policies such as tax increase in 2011 and 2014, expansion of smoke-free areas in 2009 and 2010, and pictorial health warnings on behavioural change of smokers and ex-smokers; collected the opinions on current policies such as smoke-free areas, pictorial health warnings and point of sale displays, and the opinions towards future policies such as tax increase, plain packaging, and tobacco endgame. The results of the two waves have been used by COSH to advocate plain packaging, banning on point of sale displays, and increasing tobacco tax by 100% in the past 2 years.

In order to collect further information on issues related to tobacco control which should be addressed in future tobacco control measures in Hong Kong, COSH commissioned School of Public Health (SPH), the University of Hong Kong (HKU), to conduct a third wave of the survey (2014/15). The current survey sought to use the Hong Kong data to update information on the prevalence of SHS and active smoking and its health effects, use of E-cigarettes, awareness of smoking cessation services and to identify the level of public support for current and future tobacco control measures as well as estimating the impact of existing policies.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The prevalence of active smoking in Hong Kong (time frame: Outcome will be assessed immediately after subjects answer the questionnaire as this is a cross-sectional survey). It is what the study was designed to measure, not a finding.
