We investigated whether endurance exercise training (EXT) ameliorates circadian rhythm (CR)-induced risk factors by improving skeletal muscle (SKM) mitochondrial biogenesis, reducing oxidative stress, and modulating apoptotic protein expression. We distinguished between regular and shift workers using the National Health and Nutrition Examination S...

Particulate matter (PM) has various health effects, and individuals are simultaneously exposed to these factors. Vulnerable and susceptible individuals are more sensitive to environmental factors than nonvulnerable individuals. Exposure to PM causes cardiovascular diseases. Heart rate variability (HRV) is a biomarker that may be used to identify ca...

Many epidemiological studies noted a correlation between prenatal phenol exposure and various fetal growth indicators, such as estimated fetal weight, weight and length at birth, and head/abdominal circumference, but showed inconsistent findings. This study aimed to ascertain environmental phenol levels in pregnant women who have high-risk factors...

Introduction Previous studies have extensively examined the relationship between social support and various health outcomes. However, little is known about the distinct longitudinal associations between perceived social support and the development of cardiovascular events in patients with metabolic syndrome. In this cohort study, we investigated wh...

Purpose We investigated the association between social support, metabolic syndrome, and incident cardio-cerebrovascular disease (CCVD) in rural Koreans aged ≥50 years. Materials and Methods We conducted a prospective study using the Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population (KoGES-...

Background According to the results of the age-standardized suicide rate (suicide deaths per 100,000 population) published by Organization for Economic Cooperation and Development countries from 2003 to 2019, the suicide rate in Korea is ranked first almost every year, so it should be managed at the national level. To reduce the suicide rate, many...

Background: Low-density lipoprotein cholesterol is an important marker highly associated with cardiovascular disease. Since the direct measurement of it is inefficient in terms of cost and time, it is common to estimate through the Friedewald equation developed about 50 years ago. However, various limitations exist since the Friedewald equation wa...

Objective: The aim of this study was to develop, compare, and validate models for predicting cardiovascular disease (CVD) mortality and hospitalization with hypertension using a conventional statistical model and a deep learning model. Methods: Using the database of Korean National Health Insurance Service, 2,037,027 participants with hypertensi...

Introduction: Noninvasive digital biomarkers are critical elements in digital healthcare in terms of not only the ease of measurement but also their use of raw data. In recent years, deep learning methods have been put to use to analyze these diverse heterogeneous data; these methods include representation learning for feature extraction and superv...

Abstract Objectives: To propose the cutoff value of handgrip strength (HGS) for each metabolic syndrome component in Korean adolescents. Methods: Total of 2303 adolescents (1226 boys and 1077 girls; age 10-18 years) who participated in the Korea National Health and Nutrition Examination Survey from 2014 to 2017. We used the International Diabetes F...

Hypertension and diabetes mellitus are major chronic diseases that are important factors in the management of cardiovascular disease. In order to prevent the occurrence of chronic diseases, proper health management through periodic health check-ups is necessary. The purpose of this study is to determine the incidence of hypertension and diabetes me...

Introduction : The worldwide prevalence of non-alcoholic fatty liver disease in adolescents is increasing. Measuring handgrip strength is a simple and non-invasive method for assessing sarcopenia in adolescents. However, the association between handgrip strength and laboratory values has not yet been evaluated in a clinical setting. This study prop...

Glycogen storage disease (GSD) is a rare disease that can cause life-threatening problems owing to metabolic errors in storing or using glycogen. The disease course of GSD remains unknown, despite medical technology advances. We determined the prevalence and complications of GSD using data from the National Health Insurance Service database. Data w...

Background: Early recognition and prompt intramuscular epinephrine administration are critical for the treatment of anaphylaxis. The special emergency medical service team (SEMST) is a reorganization plan that incorporates first-level emergency medical technicians (EMTs) and nurses from Korea to give the authority to administer epinephrine. This s...

Objectives: This study aimed to identify factors related to smoking experience among Korean adults according to gender.Methods: The analysis used the data collected from 19,974 who had a smoking experience from The Korea National Health and Nutrition Survey (2007-2018). Collected data were analyzed using descriptive statistics, t-test, Logistic reg...
