Ischemic heart disease mortality due to fine particulate matter in Seoul between 2016 and 2020
Our study assessed the burden of IHD mortality attributable to ambient PM 2.5 and the potential health benefits associated with its reduction in Seoul between 2016 and 2020. The findings suggest that continued efforts to reduce PM 2.5 concentrations could significantly mitigate IHD mortality, particularly in the context of an aging population
Infantile allergic diseases
The result indicates that prenatal white fish intake at least once a week reduces the risk of ADs in infants, especially in the group with high prenatal mercury exposure
Prenatal Exposure to Traffic-Related Air Pollution and the DNA Methylation in Cord Blood Cells
Particulate matter with a diameter of ≤10 μm (PM 10 ) and nitrogen dioxide (NO 2 ) affect the DNA methylation in the fetus, but epigenetic studies regarding prenatal exposure to air pollution in Asia are lacking. Therefore, this study aimed to assess whether there is any association between the ambient concentrations of PM 10 and NO 2 and CpG methylation in the cord blood DNA by using a Korean birth cohort. The concentrations of the air pollutant…
Association between Phthalate Exposure and Frailty among Community-Dwelling Older Adults
Only a few studies have examined the impacts of environmental exposure on frailty. This study investigated the association between phthalates and frailty among community-dwelling older adults. The Korean Elderly Environmental Panel II (KEEP II) study is a repeated panel data study of 800 community-dwelling older adults in South Korea. Frailty was measured with five items defined by Fried and colleagues. Environmental pollutants in the form of two…
Children’s Greenness Exposure and IQ-Associated DNA Methylation
Epigenetics is known to be involved in regulatory pathways through which greenness exposure influences child development and health. We aimed to investigate the associations between residential surrounding greenness and DNA methylation changes in children, and further assessed the association between DNA methylation and children's intelligence quotient (IQ) in a prospective cohort study. We identified cytosine-guanine dinucleotide sites (CpGs) as…
Decrease in Ambient Fine Particulate Matter during Covid-19 Crisis and Corresponding Health Benefits in Seoul, Korea
Both domestic emissions and transported pollutants from neighboring countries affect the ambient fine particulate matter (PM 2.5 ) concentration of Seoul, Korea. Diverse measures to control the coronavirus disease 2019 (COVID-19), such as social distancing and increased telecommuting in Korea and the stringent lockdown measures of China, may reduce domestic emissions and levels of transported pollutants, respectively. In addition, wearing a parti…
Exposure to ambient fine particulate matter is associated with changes in fasting glucose and lipid profiles
Fine particulate matter exposure affects worsening fasting glucose and low-density lipoprotein cholesterol levels, with no evidence of an association for coarse particulate matter
Serum 25-hydroxyvitamin D and hypertension in premenopausal and postmenopausal women
Objective: A recent meta-analysis suggested that the association between vitamin D and risk of hypertension was markedly stronger in women aged Design: A cross-sectional population survey conducted by the US Centers for Disease Control and Prevention, National Center for Health Statistics. Setting: The National Health and Nutrition Examination Surveys (NHANES) 2007–2010 formed the setting for the present study. Participants: We analysed data from…
Sex-dependent and body weight-dependent associations between environmental PAHs exposure and insulin resistance
BACKGROUND: The prevalence of metabolic diseases rises rapidly with an ageing population. Recent studies suggest the potential involvement of environmental chemicals in insulin resistance (IR) that plays a core role in the development of metabolic diseases. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous components of outdoor and indoor air pollution. The influence of PAHs on IR may differ depending on sex and weight. OBJECTIVES: We examin…
Urinary bisphenol A concentrations are associated with abnormal liver function in the elderly
BACKGROUND: Bisphenol A (4,40-isopropylidenediphenol, BPA) is known to adversely affect various organs. The liver is reported to be affected by BPA in animal studies. However, there are few studies in humans on the effects of BPA on the liver. Therefore, we evaluated the relationship between urinary BPA levels and liver function in elderly subjects using repeated measurements. METHODS: From 2008 to 2010, a total of 560 elderly subjects residing i…
Seasonal variation of effect of air pollution on blood pressure
Background: Many studies have shown a consistent association between ambient air pollution and an increase in death due to cardiovascular causes. An increase in blood pressure is a common risk factor for a variety of cardiovascular diseases. However, the association between air pollution and blood pressure has not been evaluated extensively. Methods: In this cross-sectional study, we measured blood pressure in 10 459 subjects who had a health exa…
