Plasma lipid, lipoprotein and apolipoprotein levels in a random population sample of 2875 Hong Kong Chinese adults and their implications (NCEP ATP-III, 2001 guidelines) on cardiovascular risk assessment.
The age- and sex-related levels of plasma lipids, lipoproteins and apolipoproteins in a random population sample of 2875 Hong Kong Chinese Adults (1397 men and 1478 women aged 25-74) and their implications on cardiovascular risk assessment are reported. Total cholesterol, low-density lipoprotein (LDL)-cholesterol and triglycerides increased with age in both sexes. Postmenopausal women had the worst profiles. They also showed higher triglyceride and non-high density lipoprotein (non-HDL)-cholesterol and had higher percentage of values greater than the desirable limits, compared with men of the same age groups. Overall 39% of men and 29% of women had non-HDL cholesterol of 4.2 mmol/L or greater. Apolipoproteins A-I and B followed the same trends as HDL-cholesterol and LDL-cholesterol, respectively. Apolipoprotein E (apo E) allele frequencies were: epsilon2 8.7, epsilon3 80.4 and epsilon4 10.9% with the genotype having a significant effect on plasma apo E concentration (p < 0.001). Carriers of the epsilon2 allele had higher apo E values than those homozygous for E3. Lipoprotein(a) levels were higher in women than men (geometric mean 152 versus 102 mg/L, p < 0.05) and in women with FSH above versus below 40 IU/L (185 versus 136 mg/L, p < 0.05). With respect to the NCEP ATP-III 2001 guidelines, the prevalence of hyperlipidemia in the Hong Kong population approached those in high CHD prevalence Caucasian communities. Local management guidelines and community-wide programs to reduce fat intake, increase regular moderate exercise and reduce the prevalence of overweight and obesity are urgently required, and hormone replacement therapy for postmenopausal women might be warranted.
