Abstract

The purpose of this study was to investigate the body composition, biochemical parameters, and consumption of convenience foods according to leptin receptor polymorphism in university students. A survey was conducted on a total of 418 students - 271 males and 147 females. Based on a self-reporting method, questionnaires were administered for over 20 minutes, and leptin receptor and blood samples were analyzed. The genotype frequencies of leptin receptor polymorphism were Gln/Arg heterozygote (64.8%) and Gln/Gln homozygote (35.2%). Leptin polymormphism showed no significant association with biochemical parameters(ALT, cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, and hemoglobin) and body composition. GG homozygote was associated with a higher risk of visceral fat obesity compared to those with GA heterozygote (odd ratio 1.758, 95% confidence intervals 0.812~3.803). Leptin polymorphism appeared to be a genetic risk factor for visceral fat obesity. This study suggests that leptin polymorphism has a causative role to body fat distribution in Korean.
