The lipid and lipoprotein profile of the urban black South Africa population of the Cape Peninsula - the BRISK study.
OBJECTIVE
To determine the lipid and lipoprotein profile of the urban black South African population of the Cape Peninsula.


METHODS
Cross-sectional design.


METHODS
The seven black residential areas of the Cape Peninsula.


METHODS
A stratified proportional sample was drawn from the study area. The sample consisted of 422 men and 544 women aged between 15 and 64 years.


METHODS
Lipid and lipoprotein levels. Risk levels for coronary heart disease (CHD).


RESULTS
The total cholesterol (TC level) was low compared with other South African groups studied. Men had a mean TC of 3.98 mmol/l and women 4.15 mmol/l. Low-density lipoprotein cholesterol (LDLC) values for men (2.03 mmol/l) were lower than those for women (2.30 mmol/l). Men (1.35 mmol/l) and women (1.37 mmol/l) had similar high-density lipoprotein cholesterol (HDLC) levels. Both sexes had a prevalence of protective HDL/TC ratios above 30% for all age groups. High HDL3C levels and low HDL2C levels were found in both men and women. Apolipoprotein A and B followed the trends of HDLC and LDLC and showed no difference between the sexes. The plasma triglyceride (TG) levels increased with age in both sexes. Men displayed higher TG levels than women in all age groups. Seventeen per cent of men and 26% of women had a moderate-to-high risk for CHD, given their TC levels. Other lipid-related risk factors indicated low risk for CHD.
