BACKGROUND: Few studies have evaluated the association between being underweight and having cardiovascular disease in the general population. We investigated the incidence of stroke, myocardial infarction (MI), and all-cause mortality according to detailed underweight categories in a large population cohort. METHODS: We included 4 164 364 individuals who underwent a health examination that was conducted as part of the Korean National Health Insurance Service between January 2009 and December 201

Abstract In studies evaluating the association between body mass index (BMI) and risk of tuberculosis (TB), the data for the underweight population has been limited and results were conflicting. Our study aimed to evaluate whether being underweight increases the risk of TB using a nationwide representative sample from the Republic of Korea. A large population-based cohort study of over ten million subjects who participated in the health screening in 2010 was performed using the Korean National H

Objective To examine the associations between the allergic triad (asthma, allergic rhinitis, atopic dermatitis) and risk of dementia. Methods Participants comprised 6,785,948 adults aged ≥40 years who participated in a national health examination in 2009 without any history of dementia before baseline. From 2009 to 2017, we prospectively investigated the associations between physician‐diagnosed allergic diseases and risk of incident dementia (all‐cause, Alzheimer's disease [AD], vascular dementi

Prolonged sedentary time was significantly associated with high diastolic BP and low HDL cholesterol level in Korean adults. The associations were independent of general and abdominal obesity and moderate-to-vigorous physical activities.

Abstract Existing data for the association between late-life body mass index (BMI) and the risk of Alzheimer’s disease (AD) in the underweight population are limited with conflicting results. A large population-based cohort study of 148,534 individuals aged ≥ 65 years who participated in the national health screening program from 2002 to 2005 was performed using the Korean National Health Insurance Service-Senior cohort database 2006–2015. The risk of AD according to BMI category (kg/m 2 ) in As

AIM: This study aimed to evaluate the association between weight change and mortality in Korean older adults. METHODS: We collected data pertaining to National Screening Program participants aged ≥65 years from the Korean National Health Insurance Corporation records during 2005-2011. To this data, we included mortality data, such as the date of death, of these patients (up to and including 2017) from Statistics Korea. We defined weight change as a difference in bodyweight measured in the Nation

In this nationwide study, underweight was more prevalent among women, older adults aged ≥80 years, and low-income individuals. Disparities in severe underweight widened across sociodemographic subgroups over time.

Sunlight exposure and oral supplementation are the key strategies to increase serum 25-hydroxyvitamin D [25(OH)D] concentration. We aimed to determine elevation in serum 25(OH)D levels by comparing sunlight exposure and oral vitamin D supplementation in vitamin D-deficient participants who chose the treatment strategy by shared decision-making. We enrolled 197 participants aged ≥19 y who had vitamin D deficiency (serum 25(OH)D<20 ng/mL). Participants selected their treatment method through share

A higher PA level was associated with a lower prevalence and severity of total, voiding, and storage LUTS in a dose-dependent manner in Korean men.

The purpose of this study was to investigate the association between long-term air pollution exposure and Low Urinary Tract Symptoms (LUTS) in Korean men. This study included 7,979 adult men who underwent health checkups. Each subject’s annual average air pollution exposure levels were estimated using the Community Multiscale Air Quality model. LUTS were evaluated using the International Prostate Symptom Score (IPSS) questionnaire, and the IPSS values were analyzed for their association with LUT

This study assessed the marginal utilities and public burdens of hearing loss and eight chronic diseases in a South Korean population. Although the values may vary depending on country and race, this study may provide an indispensable foundation for more detailed studies on hearing loss.

Steatotic liver disease (SLD), the most common chronic liver disease, imposes significant health and economic burdens. This study examined the association between long-term exposure to ambient air pollutants and SLD risk and severity in a population with relatively lower pollution levels. We analyzed 20,553 participants who underwent health screening from 2015–2019. Five-year exposures to PM 2.5 , PM 10 , NO 2 , SO 2 , and CO were estimated using nationwide monitoring data and modeled concentrat
