Abstract
PURPOSE: To establish the lipid pattern in subjects with diabetes mellitus (DM) and factors that are correlated with insulin resistance and lipid disorders in a population of Bali. METHODS: A cross-sectional population-based study which enrolled 1840 subjects (age 13-100 years) from 7 villages was carried out. Several clinical parameters were measured including age, gender, body mass index, waist circumference (WC), fasting blood glucose, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein (apo) A (apoA), apoB, non-HDL-C, T/HDL-C ratio, LDL-C/apoB ratio, apoB/A ratio, plasma insulin, and homeostasis of model assessment-insulin resistance (HOMA-IR). RESULTS: TC, TG, and non-HDL-C levels were higher in DM subjects than in normal glucose tolerance (NGT) subjects in both genders; total/HDL-C ratio was higher in subjects with DM than in NGT subjects only in men; LDL-C levels, apoB levels, and apoB/A ratios were higher and LDL/apoB was lower in subjects with DM than in NGT in women. In subjects with DM, the target for LDL-C (79%), non-HDL-C (85.2%), apoB (80%), HDL-C (34.9%), TG (46.7%), and small-dense low density lipoprotein (42.2%) was not achieved. CONCLUSION: FBG was correlated with TC, TG, LDL-C, apoB, non-HDL-C levels, LDL/apoB, and apoB/apoA ratios. Subjects with DM had higher levels of TC, TG, and non-HDL-C levels in both genders; T/HDL-C ratio only in men; LDL-C, apoB/apoA ratio and lower LDL/apoB ratio only in women. Obesity was correlated with lipid levels. WC was correlated with LDL/apoB ratio, insulin level, HOMA-IR, and TG; highest absolute strength of correlation was with LDL/apoB ratio. Insulin resistance was correlated with lipid levels or ratios, especially in women. In women, HOMA-IR had a positive correlation with total/HDL-C ratio, non-HDL-C, apoB, and a negative correlation with HDL-C levels.
