In previous studies, there were debates on the association between handgrip strength (HGS) and prevalence of metabolic syndrome. Since body weight is associated with both HGS and prevalence of metabolic syndrome, whether HGS is corrected with body weight (relative HGS) or not (absolute HGS) can directly influence outcome of the study. Therefore, this study analyzed the relationship between HGS and prevalence of metabolic syndrome using both relative and absolute HGS.

Methods: This study included 1695 adults (500 males and 1,195 females), who took part in a regular health check-up at the community-based health promotion center. Participants were divided according to degree of adiposity and the presence of NAFLD.
Background: The purpose of the current study was to investigate the association between cardiorespiratory fitness (CRF), measured by a simple step test, and the prevalence of metabolic syndrome among Korean adults, in a cross sectional design.
Methods: A total of 1,007 Korean adults (488 men and 519 women) who underwent routine health checkups were recruited. CRF was measured by Tecumseh step test.

Background: Recently, osteocalcin (OC), an osteoblast-derived hormone, has been suggested as a new link between obesity and insulin resistance in humans. However, few studies regarding the relationship between OC and obesity in Asian children have been published. We investigated the association of OC with adiposity, insulin resistance and metabolic syndrome (MetS) in Korean children.

To investigate the effects of Active Hexose Correlated Compound (AHCC) supplementation and the mechanism action of AHCC in patients with alcohol-induced mildly elevated liver enzyme levels, participants were randomly allocated to the placebo, 1 g AHCC, or 3 g AHCC group and took the supplement for 12 wk. Subjects visited the hospital for clinical and biochemical measurements, for examination of adverse events, to return unused supplements, and to obtain their next supplements. Biochemical tests including liver enzymes, a questionnaire survey, and anthropometric measurements were collected at baseline and every 4 wk thereafter.

These findings suggest that SIRT1 may play a role in the pathophysiology of visceral obesity. Therefore, we investigated the relationship between SIRT1 gene expression in circulating peripheral blood mononuclear cells (PBMCs) and abdominal visceral adiposity as measured by computed tomography.

Recently, the osteoblast-derived protein osteocalcin was found to function as a regulator of glucose and fat metabolism. However, there is a lack of studies comparing the extent of association between osteocalcin and glucose metabolism in postmenopausal versus premenopausal women.

The current study investigated the effects of lifestyle intervention on circulating chemerin level and its association with insulin resistance and adiponectin in human.
Methods: Forty male and 20 female obese adults (mean age: 29.
Background: Ferritin is known to be associated with insulin resistance (IR) and oxidative stress; however, recent studies have shown that there is an association between ferritin and anti-oxidative status. To date, the biphasic response of ferritin to oxidative stress has not been fully evaluated. Thus, we investigated the association between ferritin and IR and anti-oxidative status in obese and non-obese women.

We aimed to test 1) whether circulating PTX3 levels are associated with insulin resistance and 2) whether changes in PTX3 levels after the physical activity are associated with changes in insulin resistance.
Methods: Fifty-seven overweight or obese children (39 boys, 18 girls; age: 12.
Obesity and metabolic syndrome (MetS) are considered chronic inflammatory states. Chemerin, a novel adipokine, may play an important role in linking MetS and inflammation. We investigated the association of chemerin with inflammatory markers and with characteristics of MetS in apparently healthy overweight and obese adults.

There is growing evidence that mitochondrial dysfunction may lead to obesity and insulin resistance, which are major components of metabolic syndrome. The purpose of this study was to illuminate the relationship between mitochondrial function using leukocyte mitochondrial DNA copy number and metabolic syndrome in postmenopausal women.

Methods: The authors performed a randomized controlled trial, assigning 52 women (mean age 62.7 ± 9.
Polycystic ovary syndrome (PCOS) is associated with insulin resistance and various metabolic diseases; and recently, elevated oxidative stress has been detected in PCOS. Mitochondria are highly susceptible to oxidative damage; and disordered mitochondrial function at the cellular level can impact whole-body metabolic homeostasis, leading to the hypothesis that abnormalities in markers of mitochondrial metabolism are related to PCOS. We compared mitochondrial DNA (mtDNA) copy number in women with and without PCOS and investigated the independent relationship between mtDNA copy number and PCOS after adjustment for metabolic parameters.

Objectives: The purposes of this study were to investigate the relationships among adiponectin (a marker for adipocytokines), high-sensitivity C-reactive protein (hs-CRP, a marker for inflammation), and brachial-ankle pulse-wave velocity (ba-PWV, a marker for arterial stiffness) in MetS and to identify predictors of ba-PWV, which indicates subclinical atherosclerosis.
Background: Carcinoembryonic antigen (CEA), a serological marker of malignant tumors, demonstrates a modest increase under nonmalignant conditions and the pro-inflammatory features of CEA suggest that CEA may be related to insulin resistance and metabolic syndrome.
Methods: A total of 7075 female Korean non-smokers who underwent health check-ups were analyzed in the present study. The interquartile cutoff values for serum CEA concentrations were 0.
Background: Although therapeutic lifestyle modification (TLM) effectively improves the values of diagnostic biomarkers of metabolic syndrome, less is known about its effects on inflammatory chemokines and insulin resistance (IR) in patients with this syndrome. Objectives. To examine the effects of a short-term TLM program on inflammatory chemokines (monocyte chemoattractant protein-1 [MCP-1], retinol binding protein-4 [RBP-4]) and IR in subjects with metabolic syndrome.
View Article and Find Full Text PDFBackground: The features of the metabolic syndrome include glucose intolerance, hypertension, dyslipidemia, and central obesity, all of which are risk factors for diabetes and cardiovascular disease. Monocyte chemoattractant protein-1 (MCP-1) and interleukin-8 (IL-8) play a key role in atherosclerosis. We examined the association between chemokines, such as MCP-1 and IL-8, and metabolic syndrome.

Recent epidemiologic studies show that body fat itself may be a risk factor for osteoporosis and bone fractures. Accumulating evidence suggests that metabolic syndrome and the individual components of metabolic syndrome such as hypertension, increased triglycerides, and reduced high-density lipoprotein cholesterol are also risk factors for low bone mineral density.

Methods: Eighty-six men, aged 20 to 76 years, who visited the obesity clinic at the Division of Family Medicine, Severance hospital, Seoul, Korea were recruited for this study.
Background: The objective of this study was to determine if there is an association between serum hepatic markers and the metabolic syndrome in postmenopausal women.
Methods: This study involved 1229 postmenopausal women aged 44-85 years, who visited the Center for Health Promotion for a health check-up. We excluded subjects from the analysis if they had a daily alcohol consumption of more than 1.
Objective: The biological role and activity of visfatin, an adipokine mainly produced by visceral fat, has not been fully elucidated. The observed relationships between visfatin and metabolisyndrome are inconsistent. The purpose of this study was to illuminate the relationship between visfatin and metabolic syndrome in postmenopausal women.
