1 Prepared by Margo Eyeson-Annan New South Wales Health Survey Program, Centre for Epidemiology and Research New South Wales Department of Health March 2006 Results for the Fluoridation Questions from the NSW Population Survey

2 1 Background  Since 1997 the NSW Centre for Epidemiology and Research has conducted the NSW Population Health Survey.  The survey is an ongoing telephone survey of state residents conducted to monitor changes over time in self-reported health behaviours, health status, health service use, satisfaction with health services, and other factors that influence health  Collect data from approximately 12,000 residents annually  In September 2005 questions on fluoridation were added to the NSW Population Health Survey

3 2 Fluoridation Questions Question 1: Has fluoride been added to your public water supply? Question 2a: Do you agree with adding fluoride to your public water supply to try and prevent teeth decaying? Question 2b: Would you be in favour of adding fluoride to your water supply to try and prevent teeth decaying: In children, in adults or both? Question3: Where have you received information on water fluoridation? Question4: Who should decide on the fluoridation of water supplies?

4 3 Respondents 2084 adults aged 16 years and over completed the health survey from September 2005 to December There were approximately 250 respondents from each area health service. This sample was then weighted to adjust for differences in the probabilities of selection among subjects, and for differences between the age and sex structure of the sample and Australian Bureau of Statistics mid-year population estimates for New South Wales. This enables calculation of prevalence estimates for the population rather than for the respondents selected.
