Abstract
The prevalence of coronary heart disease (CHD) was determined in a population survey in Mauritius where the prevalence of non‐insulin dependent diabetes and mortality from CHD are amongst the highest in the world. Men and women aged 35–74 years of all major ethnic groups were included: Asian Indians (Hindus and Muslims). Creoles and Chinese. ECG abnormalities suggesting either ‘probable CHD’ or ‘possible CHD’ were defined using standard criteria. The overall prevalence of probable CHD was 2.7% in men and 0.9% in women, and that of probable or possible CHD together 17.8% in men and 33.3% in women. The prevalence of CHD did not vary significantly between the four ethnic groups. In the multivariate analyses, age and high blood pressure were the most important independent predictors of ECG abnormalities. Neither diabetes nor serum insulin seemed to contribute independently to the prevalence of CHD.This survey confirmed the high ranking of Mauritius in international mortality statistics. The high rates of CHD seen in Asian Indians, African‐origin Creoles and Chinese in the rapidly developing country of Mauritius may be a pointer to future problems in their regions of origin.
