Previous studies have reported an inconsistent relationship between alcohol consumption and bone health. A growing body of research has shown that chronic alcoholism leads to osteopenia and increased incidence of skeletal fractures, but some studies have concluded that alcohol consumption may be associated with higher bone mineral density in elderly(More)
Childhood obesity is directly related to cardiovascular disease (CVD) risk factors, but there is limited information on their relation in Korean children and adolescents. The authors investigated the association between obesity and CVD risk factors among 2,272 Korean boys and girls aged 10-18 years, who participated in the Korean National Health and(More)
OBJECTIVE This study examined the effect of menopausal status on the risk of the metabolic syndrome in Korean women. RESEARCH DESIGN AND METHODS Data were obtained from the Korean National Health and Nutrition Examination Survey of 2001. A total of 2,671 women who did not receive hormone replacement therapy (1,893 premenopausal women and 778(More)
BACKGROUND This study examined whether job stress (work demand and decision latitude) is associated with smoking, blood pressure, lipid level (total cholesterol, triglyceride, HDL cholesterol), and homocystein as risk factors for cardiovascular disease in Korean male workers. METHODS Study subjects of this study were recruited from a sample of 1,071(More)
This study examined the possible relationship between Karasek's job strain model and blood coagulation factors VII and VIII as risk factors for cardiovascular disease in Korean male workers. Based on the postulation of the model, we invited 160 male workers (40 people each subgroup) using a stratified sampling from the base population (n = 1071). In(More)
BACKGROUND Leptin and adiponectin are adipokines, shown to have opposing functions for fat metabolism and development of metabolic syndrome. We determined if the ratio of serum leptin to adiponectin (L/A ratio) adjunctively contributes to the risk of metabolic syndrome beyond the homeostasis model assessment of insulin resistance (HOMA-IR). METHODS This(More)
The aim of this study was to evaluate the prevalence of the metabolic syndrome, and to examine an association between the metabolic syndrome and obesity in Korean adolescents. The data for analysis were obtained from the Korean National Health and Nutrition Examination Survey 1998 and 2001. The subjects aged 12-19 years were 1317 in 1998 and 848 in 2001. A(More)
Vibrio vulnificus has been known to secrete one form of metalloprotease VvpE (45 kDa) that is cleaved to 34 kDa-VvpE and 11 kDa-C-terminal propeptide via extracellular autoproteolysis. However, we found that extracellular secretion of both the 34 and 45 kDa forms of VvpE began in the early growth phase; moreover, 34 kDa-VvpE existed as the major form in V.(More)
A growing body of literature has documented that job stress is associated with the development of cardiovascular disease. Nevertheless, the pathophysiological mechanism of this association remains unclear. The purpose of this study is to elucidate the relationship between job stress, heart rate variability, and metabolic syndrome. The study design was(More)
Carotid intima-media thickness (CIMT) is considered as a surrogate marker for cardiovascular disease (CVD). We determined the normative value of CIMT and correlates of CVD risk factors and Framingham risk score (FRS) in Korean rural middle-aged population. We measured CIMT with a B-mode ultrasonography in 1,759 subjects, aged 40 to 70 yr, in a(More)
