Background: Sedentary behavior has been shown to have deleterious effects on cardiovascular outcomes. This study aimed to examine the association between sedentary time and cardiovascular risk factors in Korean adults.

Methods: A cross-sectional study was performed using data from adults aged 19 years and above in the 2013 Korean National Health and Nutrition Examination Survey.

Silicon Diphosphide: A Si-Based Three-Dimensional Crystalline Framework as a High-Performance Li-Ion Battery Anode.

The development of an electrode material for rechargeable Li-ion batteries (LIBs) and the understanding of its reaction mechanism play key roles in enhancing the electrochemical characteristics of LIBs for use in various portable electronics and electric vehicles. Here, we report a three-dimensional (3D) crystalline-framework-structured silicon diphosphide (SiP2) and its interesting electrochemical behaviors for superior LIBs. During Li insertion in the SiP2, a three-step electrochemical reaction mechanism, sequentially comprised of a topotactic transition (0.

Design and baseline characteristics of participants in the Enhancing Physical Activity and Reducing Obesity through Smartcare and Financial Incentives (EPAROSFI): A pilot randomized controlled trial.

Background: An activity tracker combined with a smartphone application (smartcare) may help people track and receive feedback on their own activities. However, activity trackers themselves generally fail to drive long-term sustained engagement for a majority of users. One potential strategy for increasing the effectiveness of smartcare is through the use of incentives.

Dietary Fat Intake and the Risk of Metabolic Syndrome in Korean Adults.

Background: The effect of dietary fat intake on the risk of cardiovascular disease remains unclear. We investigated the association between dietary fat and specific types of fat intake and the risk of metabolic syndrome.

Methods: The study population included 1,662 healthy adults who were 50.

Increased bone mineral density according to increase of skeletal muscle mass in 534 Korean women: A retrospective cohort study conducted over 2.7 years.

Objective: To determine the impact of the changes in the amount of abdominal fat, directly measured by computed tomography, body composition, and the metabolic syndrome (MetS) risk factors on the bone mineral density (BMD) of Korean women.

Methods: A retrospective cohort study involving 534 Korean women aged 29 to 78 years, who had undergone both dual-energy X-ray absorptiometry and abdominal adipose tissue analysis by computed tomography scan more than twice between January 2004 and December 2010. The changes in the BMD values were examined in association with the changes in fat amount, body composition parameters, and risk factors of MetS.

Association between metabolic syndrome and Helicobacter pylori infection diagnosed by histologic status and serological status.

Goals: We aimed to simultaneously evaluate the association between metabolic syndrome and Helicobacter pylori (HP) infection diagnosed histologically and serologically in a large number of healthy Korean adults.

Background: Serological positivity for HP does not necessarily indicate current infection. No study to date has compared the association between metabolic syndrome and HP infection diagnosed by histologic and serological status.

Lack of Association between Self-reported Saltiness of Eating and Actual Salt Intake.

Background: Reducing salt intake is known to be an important factor for lowering blood pressure and preventing cardiovascular disease. Estimating amount of salt intake is a necessary step towards salt intake reduction. Self-reported saltiness of diet is a method most easily used to measure a patient's salt intake.

Associations of smoking and smoking cessation with CT-measured visceral obesity in 4656 Korean men.

Objectives: Although obesity is shown to be less common among current smokers than never smokers, the association between visceral obesity and smoking remains uncertain.

Methods: For this cross-sectional analysis, we recruited 4656 Korean men of 19 to 79 years who received a regular checkup at a health examination center between 2008 and 2010. Computed tomography was performed to measure the area of visceral and subcutaneous adipose tissue (VAT and SAT).

No significant association of aspirin use with cerebral microbleeds in the asymptomatic elderly.

Background And Purpose: Cerebral microbleeds (CMBs) may predict future risk for intracerebral hemorrhage (ICH). ICH is one of the most important complications of aspirin use. The association between aspirin use and CMBs is still controversial.

Association of obesity with cerebral microbleeds in neurologically asymptomatic elderly subjects.

Obesity is associated with an increased risk of cardiovascular disease, but few studies have investigated the effects of obesity on subclinical cerebrovascular disease. Cerebral microbleeds (CMBs) are radiological markers of cerebral small vessel disease and reflect underlying vasculopathy. In this context, we assessed whether obesity was related to CMBs and to CMB subtypes categorized by location.

Effect of central obesity on prostate specific antigen measured by computerized tomography: related markers and prostate volume.

Purpose: We assessed the effects of central adiposity represented by visceral adipose tissue on prostate volume, prostate specific antigen, and prostate specific antigen mass and mass ratio.

Materials And Methods: This cross-sectional study included 6,389 Asian men 30 to 79 years old. Prostate volume was estimated by transrectal ultrasound.

Impact of visceral adiposity measured by abdominal computed tomography on pulmonary function.

Although an inverse relationship between abdominal adiposity and pulmonary function has been suggested, direct measurement of abdominal adipose tissue has rarely been attempted. Our object is to determine the impact of abdominal adiposity on pulmonary function by directly measuring abdominal adipose tissue with abdominal computed tomography (CT). In this cross-sectional study, we included never-smokers between the ages of 18 and 85 yr, who had undergone spirometry and abdominal adipose tissue analysis with CT scans during November 1, 2005 to October 31, 2009 as part of the comprehensive health examination.

Metabolic syndrome and accompanying hyperinsulinemia have favorable effects on lower urinary tract symptoms in a generally healthy screened population.

Purpose: We assessed the association of metabolic syndrome, insulin resistance and lower urinary tract symptoms in a large, screened adult population.

Materials And Methods: We analyzed 33,841 Korean men 30 years old or older who underwent routine health assessments from October 2003 to February 2010. Metabolic syndrome was defined according to the modified Adult Treatment Panel III guidelines.

The illusion of prostate-specific antigen decline in patients with metabolic syndrome and insulin resistance.

Unlabelled: What's known on the subject? and What does the study add? Studies have shown that PSA is negatively associated with obesity as a result of hemodilution or metabolic effect. Hemodilution could be the main reason for low PSA levels in obese men. However, the intrinsic metabolic effects such as insulin resistance (IR) or metabolic syndrome (MS) on PSA level have not been clearly evaluated although obesity is closely tied to MS and IR.

Milk intake and its association with metabolic syndrome in Korean: analysis of the third Korea National Health and Nutrition Examination Survey (KNHANES III).

Although previous studies have shown that milk intake has some protective effects on metabolic syndrome (MS), there are few data on the relation between MS and milk consumption in Korean. To evaluate the association between milk intake frequency and MS, 4,890 subjects (2,052 men and 2,838 women) were included in the analysis, based on the national data from representative random sample of the third Korea National Health and Nutrition Examination Survey (KNHANES III) in 2005. We conducted both univariate and multivariate logistic regression analysis with adjustment for confounding factors associated with MS.

Prostate specific antigen mass ratio potential as a prostate cancer screening tool.

Purpose: Studies suggest lowering the threshold of the prostate specific antigen test in obese men due to the hemodilution effect but prostate specific antigen may be affected by prostate volume and insulin resistance, which also increase with obesity. Thus, we examined the combined effect of these factors on prostate specific antigen.

Materials And Methods: We analyzed 3,461 Korean men 30 to 80 years old with prostate volume data available who underwent routine evaluation.

Effect of body mass index and waist circumference on prostate specific antigen and prostate volume in a generally healthy Korean population.

Purpose: We examined the influences of age, body mass index and waist circumference on prostate specific antigen before and after adjusting for prostate volume. We also examined associations among age, body mass index, waist circumference and prostate volume.

Materials And Methods: We analyzed 38,380 Korean men 30 to 79 years old who received regular checkups at our health examination center.

Development of a pain assessment tool for the older adults in Korea: the validity and reliability of a Korean version of the geriatric pain measure (GPM-K).

The purpose of this study is to develop the GPM-K and test the validity and reliability of it. GPM-K is a multidimensional pain assessment instrument for older adults. One hundred twenty-one community-dwelling old adults aged 65 and older who expressed chronic pain were included.

Developing a biological age assessment equation using principal component analysis and clinical biomarkers of aging in Korean men.

The purpose of the present study is to find clinically useful candidate biomarkers of aging, and using these to develop an equation measuring biological age (BA) in Korean men, then to validate the clinical usefulness of it. Among 4288 men who received medical health examinations, we selected 1588 men who met the normality criteria of each variable. We assumed that chronological ages (CA) of healthy persons represent the BA of them.
