Behavioural Risk Factor Survey (BRFS)
The Behavioural Risk Factor Surveillance System (BRFSS) contains information on health-related behaviours of the Hong Kong adult population collected through a series of telephone surveys conducted systematically and periodically. It is envisaged that the information will be useful for monitoring the trend of health-related behaviours, which is important for identifying emerging health issues and for planning, supporting and evaluating health promotion and disease prevention programmes.
In each survey, at least 2 000 randomly selected land-based, non-institutionalized persons aged 18 to 64 years are sampled. The eligible respondents are telephone-interviewed for about 15 minutes on their health-related lifestyle and behaviours. Each survey includes a core set of questions and other questions on specific topics of interest. During analysis, weighting is applied to age and gender in order to make the findings more representative of the general population.
The first survey was conducted in October 2004. But such survey in the form of telephone interview had been ceased from 2017 onwards.
The Centre for Health Protection is a professional arm of the Department of Health for disease prevention and control
