Statistics on behavioural risk factors

The Behavioural Risk Factor Surveillance System (BRFSS) is set up by the Surveillance and Epidemiology Branch, Centre for Health Protection of the Department of Health. It 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.

One to two surveys will be conducted each year under the BRFSS. 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. Subsequent surveys will be conducted at six to twelve-month intervals.
