“…16 However, others have used level of education or employment status as markers of socio-economic status and have shown that people with low socio-economic status are more likely to have a coronary event. 2,3,17 Similar results are presented here using the SEIFA and this suggests that when CHD is the outcome of interest, the SEIFA is a suitable measure of socio-economic status.…”

“…21,23,24 In this population, reductions in the traditional risk factors of CHD, plus the increased use of aspirin in the general population, did explain the reduction in the rate of CHD. 2 Data from the survey of risk factors showed that there were some notable associations between levels of risk factors and socioeconomic status. These associations could explain some of the difference in rates of CHD.…”

“…1 From the beginning of that period until the end of 1993 rates of CHD fell for both men and women aged 25-69 years. 2 This reduction was attributed to a reduction in the prevalence of smoking, reductions in the mean level of cholesterol and blood pressure, and an increase in the use of aspirin in the population. 2 Previous studies have used mortality data collected by the Australian Bureau of Statistics (ABS) to analyse trends in CHD mortality.…”

“…3 Furthermore, our results are not dissimilar to other studies that have used broadly equivalent methods, including studies in New South Wales, 23 Scotland 24 and England and Wales. 25,26 However, the present study does more than simply update the earlier New Zealand studies by extending the time period covered.…”

Objective: To estimate the contribution of trends in three risk factors -systolic blood pressure (SBP), total blood cholesterol (TBC) and cigarette smoking -to the decline in premature coronary heart disease (CHD) mortality in New Zealand from 1980-2004. Method: Risk factor prevalence data by 10-year age group (35-64 years) and sex was sourced from six national or Auckland regional health surveys and three population censuses (the latter only for smoking). The data were smoothed using two-point moving averages, then further smoothed by fitting quadratic regression equations (SBP and TBC) or splines (smoking). Risk factor/CHD mortality hazard ratios estimated by expert working groups for the World Health Organization Global Burden of Disease Study 2001 were used to translate average annual changes in risk factor prevalences to the corresponding percentage changes in premature CHD mortality. The expected trends in CHD mortality were then compared with the observed trend to estimate the contribution of each risk factor to the decline. Findings: Approximately 80% (73% for males, 87% for females) of the decline in premature CHD mortality from 1980 to 2004 is estimated to have resulted from the joint trends in population SBP and TBC distributions and smoking prevalence. Overall, approximately 42%, 36% and 22% of the joint risk factor effect was contributed by trends in SBP, TBC and smoking respectively. Conclusion: Our estimate for the joint risk factor contribution to the CHD mortality decline of 80% exceeds those of two earlier New Zealand studies, but agrees closely with a similar Australian study. This provides an indicator of the scope that still remains for further reduction in CHD mortality through primary and secondary prevention.
