Lipid profile in the Chinese old-old: comparison with younger age groups and relationship with some cardiovascular risk factors and presence of diseases.
In a health survey of 2,032 elderly Hong Kong Chinese aged 70 years and over selected by stratified random sampling, a subset of 199 subjects (96 M, 103 F) were selected for a study of their lipid profile. No age and sex differences were observed in mean total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride concentrations in this subgroup. Compared with values from younger Chinese subjects from a previous survey, TC and LDL-C showed an age-related rise up till about 60 years, followed by a gradual decline. HDL-C concentrations showed little variation with age. Nonagenarians had a LDL/HDL ratio similar to subjects in the < 24 age group and lower than male subjects in the age 35-64 age group. HDL-C was lower in those with heart disease or hypertension. Other lipid parameters were not influenced by the presence of other chronic diseases, self-perceived health status, or cognitive impairment. TC was positively associated with the Barthel Index, a measure of functional ability. Positive associations between obesity indices and diastolic blood pressure, and TC, LDL-C, and triglycerides were present.(ABSTRACT TRUNCATED AT 250 WORDS)
