Cardiovascular disease-related knowledge and attitudes in a high-risk Australian population

The population of Sydney's western suburbs has higher-than average mortality rates of heart disease and has raised prevalence rates of the associated risk factors. To enquire into the cardiovascular disease-related knowledge, attitudes and behaviours of this population, a survey that used a multistage area-probability sampling method was conducted in May 1987. A total of 484 subjects was interviewed. The self-reported prevalence rates of angina, heart attacks, strokes and diabetes all were high compared with the rates from the Australia-wide National Heart Foundation's Risk Factor Prevalence Study in 1983. The rates of smoking, hypertension, high blood-lipid levels and sedentary life-style also were raised. Awareness of cardiovascular disease-related issues was high but detailed knowledge often was deficient. The majority of respondents reported having attempted to change their health-related behaviours. Of special note was the finding that 80% of current smokers had tried to quit smoking. The high level of awareness of the importance of making life-style changes, and the frequency with which attempts at behavioural changes were reported, suggest that improvements in the health of the population of Sydney's western suburbs will require two complementary strategies: the teaching of the skills that are needed to maintain healthy behaviours successfully and environmental changes to facilitate healthy life-style choices.
