incident cases of increased ALT, defined as serum ALT Ն35 U/L, developed during 13 822.4 person-years of follow-up (ID, 50.6 per 1000 person-years; 95% CI, 46.9 –54.4). To minimize the effect of existing fatty infiltration on the baseline ALT, additional analyses were performed by excluding participants with incident NAFLD that occurred during the first 1(More)
AIMS C-reactive protein concentrations are decreased in Asians compared with people of white European ethnicity. It is uncertain whether C-reactive protein is a robust biomarker of cardiovascular disease (CVD) in Asians. This study aimed to determine the association between C-reactive protein and CVD and all-cause mortality in a large population of Koreans.(More)
OBJECTIVE Short and long sleep duration are associated with increased risk of clinical cardiovascular events, but the association between sleep duration and subclinical cardiovascular disease is not well established. We examined the association between sleep duration and sleep quality with coronary artery calcification (CAC) and with brachial-ankle pulse(More)
Intraocular pressure and flicker modulation sensitivity at 25 and 40 Hz were measured in 22 normal observers, with an age range from 20-71 years. Significant correlations up to 0.67 were found between intraocular pressure and flicker sensitivity at several points in the visual field. There was no correlation between flicker sensitivity and age of the(More)
BACKGROUND In nonalcoholic fatty liver disease (NAFLD), increased alanine aminotransferase (ALT) concentrations are considered to be a consequence of hepatocyte damage. We performed a prospective study to examine the association between ALT within its reference interval and risk for subsequent development of NAFLD. METHODS The study cohort comprised 5237(More)
BACKGROUND Chronic kidney disease (CKD) is a frequent, under-recognized condition and a risk factor for renal failure and cardiovascular disease. Increasing evidence connects non-alcoholic fatty liver disease (NAFLD) to CKD. We conducted a meta-analysis to determine whether the presence and severity of NAFLD are associated with the presence and severity of(More)
Few prospective studies have assessed the incidence and determinants of asymptomatic hyperuricemia in free-living populations. The authors' goals in this study were to estimate the incidence of hyperuricemia and quantify the dose-response relations of specific risk factors with hyperuricemia in middle-aged South Korean male workers. The authors followed a(More)
BACKGROUND Serum bilirubin may have potent antioxidant and cytoprotective effects. Serum bilirubin levels are inversely associated with several cardiovascular and metabolic endpoints, but their association with nonalcoholic fatty liver disease (NAFLD) has not been investigated except for a single cross-sectional study in a pediatric population. We assessed(More)
Lead (Pb), mercury (Hg), and cadmium (Cd) are common heavy metal toxins and cause toxicological renal effects at high levels, but the relevance of low-level environmental exposures in the general population is controversial. A total of 1,797 adults who participated in the KNHANES (a cross-sectional nationally representative survey in Korea) were examined,(More)
BACKGROUND/AIMS The prevalence of nonalcoholic fatty liver disease (NAFLD) in Korea has increased recently. The aim of the present study was to determine the regional differences in the prevalence and characteristics of NAFLD. METHODS From January 2009 to December 2010, 161,891 Seoul and Gyeonggi-do residents receiving a health examination at our(More)
