Stimation of reference interval of lipid profile in Assamese population

12hrs fasting samples of 1485 apparently healthy, Assamese population in the age group of 20-80 yrs., mostly from the urban area of Assam were tested for serum lipid profile that includes total cholesterol, triacylglycerol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) over a period of three years. The values (median and range in mg/dl) obtained were 170 (93-263); 110 (40-256); 40 (23-73); 103 (40-173) and 22 (8-51) respectively. After grouping these subjects according to the age and sex no significant difference were observed between most of the groups. Median and upper range of total cholesterol, HDL-C and LDL-C were found to be higher in women than in men in all the age groups. But triacylglycerol and VLDL-C concentrations were observed to be higher in the men than women except in age group of 61-70 yrs. It can be suggested that lipid values obtained in this study can be used as the reference value, based on which clinical correlation can be made.
