Sociodemographic differences in prevalence of diagnosed coronary heart disease in New Zealand estimated from linked national health records

Summary:

Linked health records, comprising hospital treatment for CHD, dispensing of selected anti-anginal drugs and mortality were used in this study to estimate sociodemographic differences in the prevalence of coronary heart disease (CHD) in New Zealand in December 2008. Among a “health contact” population of adults (≥15 years), about one in 20 (6.5% of men and 4.1% of women) had indicators of a past diagnosis or treatment for CHD or both. Prevalence differed substantially by gender, ethnic group and socioeconomic status. For example, among New Zealanders aged 35–74 years, Indian men had the highest age-adjusted prevalence (7.78%), almost double the prevalence of males in the ‘Other’ ethnic group (mainly New Zealand European). Among women, Māori had the highest adjusted prevalence (4.03%), just over twice that of ‘Others’.

Comment:
CVD risk is often considered an issue for males (as seen in many social marketing campaigns). However, the results send a clear message that prevention and management of CVD risk in Māori women is just as vital. As the editorial1 suggests, a population-wide approach, in addition to individual risk assessment, is required to reduce CVD risk. Smoking cessation is probably a good place to start, given the high rates amongst Māori women. 1. Stewart RAH.
