Abstract
BACKGROUNDS AND AIMS: We aimed to reveal the association between subclinical inflammation and metabolic risk factors and to determine the difference in the association between normal-weight and obese Korean individuals. METHODS AND RESULTS: Data collected from the Korean National Health and Nutrition Examination Survey (KNHANES) 2015, conducted from January to December 2015, were analyzed. Overall, 4620 subjects were examined and divided into two subgroups: 2987 and 1633 subjects in the normal-weight and obese groups, respectively. The prevalence of obesity in the study population was 34.5% (n = 1633). After multivariate adjustment, impaired fasting glucose (IFG) (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.05-1.42, P = 0.010), high triglyceride (TG) levels (OR 1.29, 95% CI 1.13-1.47, P < 0.001), and low high-density lipoprotein-cholesterol (HDL-C) levels (OR 1.47, 95% CI 1.31-1.64, P < 0.001) were significantly associated with increased high-sensitivity C-reactive protein (hs-CRP) levels in the normal-weight group but not in the obesity group. CONCLUSION: Subclinical inflammation was associated with IFG, high TG levels, and low HDL-C levels in normal-weight Korean individuals. Prospective and biochemical research is necessary to clarify the role of subclinical systemic inflammation in individuals with normal body weight and its impact on insulin resistance and abnormal lipid metabolism, which promote the incidence of metabolic syndrome and cardiovascular disease.
