We studied the association between the triglyceride to high-density lipoprotein cholesterol ratio and computed tomography-measured visceral fat as well as cardiovascular risk factors among Korean male adults.
We measured triglycerides, high density lipoprotein cholesterol, body mass, waist circumference, fasting plasma glucose, hemoglobin A1c, systolic blood pressure, diastolic blood pressure, visceral fat, and subcutaneous fat among 372 Korean men. The visceral fat and subcutaneous fat areas were measured by computed tomography using a single computed tomography slice at the L4-5 lumbar level. We analyzed the association between the triglyceride to high density lipoprotein cholesterol ratio and visceral fat as well as cardiovascular risk factors.
A positive correlation was found between the triglyceride to high density lipoprotein cholesterol ratio and variables such as body mass index, waist circumference, fasting plasma glucose, hemoglobin A1c, visceral fat, and the visceral-subcutaneous fat ratio. However, there was no significant correlation between the triglyceride to high density lipoprotein cholesterol ratio and subcutaneous fat or blood pressure. Multiple logistic regression analyses revealed significant associations between a triglyceride to high density lipoprotein cholesterol ratio ≥3 and diabetes, a body mass index ≥25 kg/m2, a waist circumference ≥90 cm, and a visceral fat area ≥100 cm2. The triglyceride to high density lipoprotein cholesterol ratio was not significantly associated with hypertension.
There were significant associations between the triglyceride to high density lipoprotein cholesterol ratio and body mass, waist circumference, diabetes, and visceral fat among a clinical sample of Korean men. In the clinical setting, the triglyceride to high density lipoprotein cholesterol ratio may be a simple and useful indicator for visceral obesity and cardiovascular disease.

Blood lipid profiles have been suggested to be a risk factor for osteoporosis. However, the association between lipid profiles and bone mineral density (BMD) is still unclear. This study aimed to evaluate an association between blood lipid profiles and BMD through both a cross-sectional and a longitudinal study.
Study subjects were 958 postmenopausal Korean women who have repeatedly undertaken laboratory tests and BMD measurements at lumbar spine and femur neck with an interval of 7.1 years. The associations between lipid profiles and BMD were examined using Spearman correlation analysis with an adjustment for age, smoking, alcohol drinking, physical activity, body mass index, and follow-up duration.
Lumbar spine BMD was not associated with total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HLD-C) regardless of when the measurement was performed. In an analysis using data measured at the beginning of the study, femur neck BMD was not associated with TC and LDL-C. However, femur neck BMD showed weak but significantly positive correlation with HDL-C (correlation coefficient, 0.077; 95% confidence interval, 0.005 to 0.149). When the analysis was repeated with data measured at the end of the follow-up, there was no significant correlation between femur neck BMD and any lipid profile. In addition, change in femur neck BMD during follow-up was not associated with the change in lipid profiles.
Although further study with a consideration of calcium intake and osteoporosis medication seems necessary, this study found no association between serum lipid profiles and BMD in postmenopausal Korean women.
