Key result
Between 1980 and 1983, the prevalence of current smoking fell from 32% to 29% and previously-undetected hypertension fell from 10% to 7%, alongside a 2.0 mmHg decline in mean diastolic blood pressure.

How did the prevalence of risk factors for vascular disease change in Australia between 1980 and 1983?
Absolute Event Rate: 29% vs 32%
Between 1980 and 1983 in Australia, favorable population-level trends were observed in smoking, blood pressure, and lipid profiles, although body mass index and obesity increased.
Jamrozik et al. (1989) conducted a cross-sectional in vascular disease risk factors. Survey year 1983 vs. Survey year 1980 was evaluated on prevalence of current smoking. Between 1980 and 1983, the prevalence of current smoking fell from 32% to 29% and previously-undetected hypertension fell from 10% to 7%, alongside a 2.0 mmHg decline in mean diastolic blood pressure.
