To estimate sociodemographic differences in the prevalence of coronary heart disease (CHD) in New Zealand from linked health records.
We combined records of hospital treatment for CHD, dispensing of selected anti-anginal drugs and mortality to estimate the national point prevalence of coronary heart disease in New Zealand in December 2008. Stratified estimates are presented by gender; age; Māori, Pacific, Indian and 'Other' (mainly New Zealand European) ethnic groups; and socioeconomic status.
Among a "health contact" population of adults (greater than and equal to 15 years), about one in twenty (6.5% of men and 4.1% of women) had indicators of a past diagnosis or treatment for CHD or both. Substantial differences in prevalence occurred by gender, ethnic group and socioeconomic status. For example, among New Zealanders aged 35 to 74 years, Indian men had the highest age-adjusted prevalence (7.78%; 95%CI 7.43 to 8.15), almost double the prevalence of 'Other' males. Among women, Māori had the highest adjusted prevalence (4.03%; 95% CI 3.89 to 4.17), just over twice that of 'Others.'
Major sociodemographic disparities in the national burden of CHD persist. Our results are similar to previous studies of ethnic disparities in CHD incidence, but also confirm concerns about the emerging CHD burden among South Asians. Indian males have the highest CHD prevalence of any gender-specific ethnic group. Of equal concern, Māori women have a similar prevalence to European males.
通过关联健康记录评估新西兰冠心病（CHD）患病率的社会人口统计学差异。
我们整合了冠心病住院治疗记录、特定抗心绞痛药物的配药记录以及死亡率数据，以估算2008年12月新西兰冠心病的全国时点患病率。按性别、年龄、毛利族、太平洋岛民、印度族和“其他”（主要是新西兰欧洲裔）族裔群体以及社会经济地位呈现分层估算结果。
在15岁及以上的成年“健康接触”人群中，约二十分之一（男性为6.5%，女性为4.1%）有既往冠心病诊断或治疗指标或两者皆有。患病率在性别、族裔群体和社会经济地位方面存在显著差异。例如，在35至74岁的新西兰人中，印度男性年龄调整后的患病率最高（7.78%；95%置信区间为7.43至8.15），几乎是“其他”男性患病率的两倍。在女性中，毛利族调整后的患病率最高（4.03%；95%置信区间为3.89至4.17），略高于“其他”女性患病率的两倍。
冠心病全国负担方面的主要社会人口统计学差异依然存在。我们的结果与之前关于冠心病发病率种族差异的研究相似，但也证实了对南亚人中新出现的冠心病负担的担忧。印度男性是所有特定性别族裔群体中冠心病患病率最高的。同样令人担忧的是，毛利族女性的患病率与欧洲男性相似。
