Coronary risk factors in the coloured population of the Cape Peninsula
Insights
This study found that the coloured population has a high prevalence of coronary heart disease risk factors, including smoking, hypertension, and hypercholesterolemia. Urgent preventive strategies are needed to address these modifiable risk factors.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Coronary heart disease (CHD) poses a significant health burden globally.
- Identifying population-specific risk factors is crucial for targeted prevention.
- Previous research has not extensively detailed CHD risk profiles in the South African coloured population.
Purpose of the Study:
- To assess the prevalence of major reversible and other risk factors for coronary heart disease (CHD) in a random sample of the coloured population in South Africa.
- To compare the risk factor profile with other South African population groups.
- To highlight the need for preventive interventions.
Main Methods:
- A cross-sectional study was conducted on a random sample of 976 individuals from the coloured population.
- Data collected included smoking status, blood pressure (hypertension), serum cholesterol levels (hypercholesterolemia), and other lifestyle and clinical factors.
- Prevalence rates of various risk factors were calculated.
Main Results:
- A high prevalence of major reversible risk factors was observed: 56% of men and 40% of women smoked; 18% were hypertensive; 17% were hypercholesterolemic.
- Over 80% of the population exhibited at least one risk factor at lower, yet significant, levels.
- Other common risk factors included inactivity, overweight, hyperuricaemia, hypertriglyceridaemia, and a positive family history of CHD.
Conclusions:
- The coloured population studied is at substantial risk of coronary heart disease due to the high prevalence of modifiable risk factors.
- Significant differences exist when compared to risk profiles of other South African populations.
- There is a clear and urgent need for the implementation of targeted preventive strategies within this population group.
Abstract:
A cross-sectional study of risk factors for coronary heart disease (CHD) in a random sample of 976 coloured people revealed a population greatly at risk of CHD. The major reversible risk factors--hypercholesterolaemia, hypertension and smoking--were very common, with 56% of the men and 40% of the women smoking, 18% of both men and women being hypertensive and 17% of both sexes being hypercholesterolaemic. At high cut-off points 62,8% of the men and 59,4% of the women had at least one major reversible risk factor. At lower but real levels of risk, over 80% of the population was affected. Other risk factors such as inactivity, overweight, hyperuricaemia, hypertriglyceridaemia and a positive family history of CHD were all common in this population group. A 'protective' high-density lipoprotein cholesterol level of greater than or equal to 20% of the total serum cholesterol level was found in 74,5% of the men and 81,1% of the women. A comparison with available data on other South African population risk profiles shows marked differences. The need for preventive strategies in the coloured population is clear.
