A prevalence survey of lipids abnormalities of rural area in Amphoe Phon, Khon Kaen.

ABSTRACT

A population survey in 13 villages and 3 sub-districts of a rural area in Amphoe Phon, Khon Kaen showed that mean cholesterol and high density lipoprotein cholesterol (HDL-C) level were 163.0 +/- 35.3 and 29.6 +/- 9.1 mg/dl respectively which is very low compared to Bangkok and other affluent countries. The cholesterol level in females was higher than in males (male 158.0 +/- 33.2, female 166.6 +/- 36.4) and the HDL-C level in males was higher (30.2 +/- 9.0 vs 29.1 +/- 9.2). The cholesterol level increased with age and obesity while HDL-C decreased with obesity. The prevalence of hypercholesterolemia and low HDL-C was 3.0 and 74.9 per cent respectively. The diet of the survey population was high in carbohydrate (80% of calories) and fat intake was very low (8% of calories). The factors which were associated with high cholesterol levels were age, female sex, obesity and increased fat intake while those of low HDL-C were obesity and being a farmer. The low fat intake may explain for the low total cholesterol, HDL-C HDL-C/cholesterol ratio observed in our population compared to other studies.
