UNLABELLED: There have been several reports about the clinical association between type 2 diabetes mellitus (DM) and nonalcoholic fatty liver disease (NAFLD). However, most of the studies were about the unilateral effects of type 2 DM on NAFLD, and studies on the reverse relation are rare. Thus, this study was designed to investigate the effect of NAFLD on type 2 DM. We conducted a prospective cohort study on 25,232 Korean men without type 2 DM for 5 years. We serially checked the various metabo

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is getting an increasing attention for its clinical implications on cardiovascular disease (CVD). However, epidemiologic data are not so evident to sustain the causative association between NAFLD and hypertension, the major cause of CVD. Accordingly, we designed this study to investigate the clinical association between NAFLD and the development of hypertension. METHODS: To assess the natural course of blood pressure according to degr

There have been many studies between serum uric acid (UA) and chronic kidney disease (CKD). However, as far as we know, little research has been done to examine the prospective association between serum UA and development of CKD in Korean men. This prospective cohort study was performed using 18,778 men who participated in a health checkup program both on January, 2005 and on December, 2009. CKD was defined as an estimated glomerular filtration rate < 60 mL/min per 1.73 m(2). The odds ratio (OR)

BACKGROUND: Components of the metabolic syndrome (MetS), such as elevated fasting glucose levels and abdominal obesity, have been suggested as potential risk factors for pancreatic cancer. However, data are still insufficient to assure the influence of MetS on incident pancreatic cancer. The objective of the current study was to investigate the association between MetS, metabolic components, and the risk of pancreatic cancer. METHODS: In the Korea National Health Information Database, 223,138 in

Previous epidemiologic studies have shown the clinical association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD). However, there is only limited information about the effect of NAFLD on the development of hypertension. Accordingly, we investigated the clinical association between NAFLD and prehypertension. A prospective cohort study was conducted on the 11,350 Korean men without prehypertension for 5 yr. The incidences of prehypertension were evaluated, and C

BACKGROUND: Elevated serum uric acid (UA) could be a risk factor for hypertension, type 2 diabetes mellitus and cardiovascular disease. In addition, elevated serum UA may be associated with impaired renal function. However, it is unclear whether elevated serum UA is a cause of microalbuminuria or not. Therefore, we performed a prospective cohort study of the temporal relationship between baseline elevated serum UA and the development of microalbuminuria in Korean men. DESIGN AND METHODS: A micro

BACKGROUND AND OBJECTIVE: Elevated serum ferritin levels have been reported to be associated with several metabolic disorders. We investigated the relationship between serum ferritin level and metabolic syndrome and its components in healthy Korean men. METHODS: In this cross-sectional study, serum ferritin level and metabolic syndrome and its components were measured from 18 581 men from January to December in 2008. The presence of metabolic syndrome was determined according to the most recent

AIMS: In recent years, γ-glutamyltransferase has emerged as a predictor of cardiovascular disease, Type 2 diabetes mellitus, the metabolic syndrome and hypertension. However, it is not yet certain whether γ-glutamyltransferase is a predictor for insulin resistance. The aim of this study was to examine the longitudinal association between baseline γ-glutamyltransferase level and the development of insulin resistance in Korean men. METHODS: We performed a prospective cohort study, involving 22 931

BACKGROUND AND AIM: Cholelithiasis is one of the most common gastrointestinal diseases worldwide. The metabolic syndrome (MetS), a combination of various metabolic abnormalities, is also common with a continually increasing prevalence. These diseases are associated with several risk factors. However, data on the association between MetS components and cholelithiasis are insufficient. This study aimed to analyze the association of MetS and its components with the incidence of cholelithiasis using
