BACKGROUND: In February 2020, a coronavirus disease 2019 (COVID-19) outbreak was reported in fitness centers Cheonan, Korea. METHODS: From 24 to March 13, an epidemiological investigation conducted on the center outbreak. All those who were screened tested for severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) using real-time reverse transcriptase polymerase chain reaction. Contacts traced and self-isolated 14 days. We determined characteristics of confirmed cases SARS-CoV-2...
Methylmercury is well known for causing adverse health effects in the brain and nervous system. Estimating elimination constant derived from biological half-life of methylmercury blood or hair an important part calculating guidelines intake. Thus, this study was conducted to estimate Korean adults. We used a one-compartment model with direct relationship between concentrations daily dietary intake methylmercury. quantified between-person variability population, informative priors were...
Lead (Pb), mercury (Hg), and cadmium (Cd) are well-known environmental pollutants. They unnecessary in the biological processes of humans. This study was performed to estimate representative background exposure levels metals by measuring concentrations whole blood Korean general population. population-based cross-sectional included 4,000 subjects (1,886 males 2,114 females) 0-83 years age 2010 2011. Adult (≥ 19 age) were collected sex- age-stratified probability method, preschool-...
Objectives Although mercury (Hg) exposure is known to be neurotoxic in humans, its effects on liver function have been less often reported. The aim of this study was investigate whether total Hg Korean adults associated with elevated serum levels the enzymes aspartate aminotransferase (AST), alanine transaminase (ALT), and gamma-glutamyltransferase (GGT). Methods We repeatedly examined blood 508 during 2010-2011 2014-2015. Cross-sectional associations between were analyzed using a...
Several epidemiological studies have reported an association between environmental pollution and various health conditions in individuals residing industrial complexes. To evaluate the effects of from complex on human health, we performed a pooled analysis epidemiologic monitoring data for residents living near national complexes Korea. The respiratory allergic symptoms prevalence acute chronic diseases, including cancer, were used as outcome variables effects. Multiple logistic regression...
Objectives: This survey was designed to conduct the first nationwide dietary exposure assessment on hazardous substances including intakes of functional food and herbal medicine. In this paper, we introduced design results status internal levels lead (Pb), cadmium (Cd), mercury (Hg). Methods: We selected 4867 subjects all ages throughout Korea. conducted a survey, biomonitoring, health survey. Results: Pb Cd were highest (median value) in seaweed (94.2 μg/kg for Pb; 594 Cd), Hg fish (46.4...
Recently several studies reported that the renal toxicity of lead (Pb) and cadmium (Cd) may exist in even a low level exposure. In terms deterioration tubular function, it affects loss divalent metals leads to other complications, so effect heavy should be well managed. Considering exposure reality, is hard find case human exposed only one metal. We designed cross-sectional study using Korean Research Project on Integrated Exposure Assessment (KRIEFS) data investigate effects multiple metal...
Although studies have shown that a low socioeconomic status (SES) is associated with high blood lead levels (BLLs) in children, the mechanism underlying this observation not well known. To determine how SES influences BLLs via environmental factors Korean we conducted population-based cross-sectional study of 4744 children aged 5–13 years. Questionnaires on sociodemographic information, factors, and food consumption were administered to children’s parents. subjects measured.The complete set...
In this study, we evaluated the associations of smoking and alcohol intake, both independently collectively, with sodium intake in Korean men. Subjects (6340 men) were from fifth National Health Examination Survey (2010–2012). Smoking-related factors included status, urinary cotinine level, pack-years smoking. Food was assessed using a 24-h recall. The odds excessive estimated survey logistic regression analysis. rate 44.1%. geometric mean level 0.05 µg/mL, median (min–max) 13.2 (0–180)....
This study was performed to select single nucleotide polymorphisms (SNPs) related the body burden of heavy metals in Koreans, provide Korean allele frequencies selected SNPs, and assess difference with other ethnicities. The candidate-gene approach method genome-wide association screening were used SNPs metals. Genotyping analysis final 192 on 1,483 subjects using VeraCode Goldengate assay. Allele differences genetic differentiations between population Chinese (CHB), Japanese (JPT),...
Competitive ELISA methods was used to measure the level of aflatoxin M1 (AFM1) from urine in 1008 Korean adults. Subjects were selected by random sampling all area Korea except Cheju-do. The recovery rate AFM1 this method 105% (73-124%). geometric mean urinary subjects 3.43 pg/mL (3.67 ng/ g creatinine). male showed statistically higher than one female subjects. However, levels not different according their age. Chungbuk-do highest concentration, whereas Kyeongnamdo lowest one. Assuming an...
Lead (Pb) is a ubiquitous toxic metal present in the environment that poses adverse health effects to humans. Inter-individual variation blood Pb levels affected by various factors, including genetic makeup. However, limited data are available on association between and levels. The purpose of this study was identify markers associated with Korean population. subjects consisted 1,483 healthy adults no history occupational exposure Pb. We measured calculated probable daily intake according...
Objectives On September 2, 2010 and November 25, 2011, the Korean Research Project on Integrated Exposure Assessment to Hazardous Materials for Food Safety (KRIEFS) organized two international symposia in Seoul, Korea. KRIEFS, established by Drug Administration March 2010, envisioned these as means obtain advanced experiences from other countries reflect refine KRIEFS's survey design methods. Methods For first symposium KRIEFS invited human biomonitoring (HBM) experts Germany, US, Canada....
Introduction: Several observational studies have shown that Attention Deficit Hyperactivity Disorder (ADHD) in children is associated with their lead exposure, but residual confounding and reversal causation can be possible explanations. In order to assess a causal association of exposure on ADHD we used Mendelian randomization method. Methods: Our study participants were recruited from the Children's Health Environmental Research (CHEER) study, 2005-2010. Of about 7,000 1828 undertaken...
Objectives: The purpose of this study is to introduce the establishment process and results Seoul Metropolitan Government's road map on environmental health policy. Methods: consisted expert group meetings, civic participation, research, questionnaire survey for priority policy agenda items in Seoul. Results: announced vision was "a healthy environment, safety Seoul". This established order define environment initiatives a period five years with an aim protect citizens' from hazardous...
Background: Several studies showed the relationship between serum homocysteine and pulse wave velocity, but their subjects were confi ned to high risk group for cardiovascular diseases recent study revealed no in young healthy adults.We hypothesized that time interval would be needed infl uence velocity after exposure vascular endothelium.The purpose of this was determine middle aged women on basis hypothesis necessity further general population. Methods:The 110 who visited a health...
