Public perception of population health risks in Canada: Health hazards and sources of information

A national survey of health risk perception among 1,503 Canadians was conducted in 2004. The current survey follows-up a previous national survey conducted in 1992 and documents changes in risk perception since that time and investigates new risk issues not previously examined. This article presents a description of the ratings of perceived risk of thirty specific hazards to the Canadian population, sources of information about health issues and risk, and confidence in these information sources. Of the specific hazards considered, behavioral risks such as cigarette smoking, obesity, and unprotected sex were seen to present the greatest risk to the health of Canadians. Hazards related to the social environment ( e. g., homelessness, street crime, unemployment) were seen as posing moderately high health risks. Medical devices or therapies ( e. g., prescription drugs, vaccines, laser eye surgery) tended to rank the lowest in terms of health risk. Women, older respondents, and those with less education reported risks as being higher than men, younger respondents, and those with more education respectively. Large geographical differences in risk perception were also observed. Participants described receiving a lot of information from the news media, medical doctors, and the Internet but reported the greatest amount of confidence in medical doctors, university scientists/scientific journals, and health brochures/ pamphlets.
