Epidemiologic relationship between alcohol flushing and smoking in the Korean population: the Korea National Health and Nutrition Examination Survey.

Although facial flushing after drinking alcohol (alcohol flushing response) is common in Asian populations, the epidemiological features in a large sample have been investigated in only a few studies. This study assessed the epidemiologic characteristics and associated factors for alcohol flushing in a Korean population. This study was based on data collected during the 2019 Korea National Health and Nutrition Examination Survey (KNHANES).

Associations between body weight change and incidence of major depressive disorder in patients with type 2 diabetes mellitus: a nationwide longitudinal follow-up cohort study of 1.1 million.

Background: Comorbid depression substantially affects the management of glycemia and diabetes-related complications among patients with type 2 diabetes mellitus. In this study, we sought to determine the association between weight change over 4 years and depression risk among patients with type 2 diabetes mellitus.

Methods: This population-based retrospective cohort study from the National Health Insurance Services of Korea included 1 111 345 patients with type 2 diabetes who were divided into groups according to body weight change over 4 years.

Psychological Stress in Parents of Children with Atopic Dermatitis: A Cross-sectional Study from the Korea National Health and Nutrition Examination Survey.

Atopic dermatitis is a chronically relapsing inflammatory skin condition that has profound impacts on quality of life of patients and their family. The aim of this study is to investigate the psychological stress in parents of children with atopic dermatitis in Korea, using data from the Korean National Health and Nutrition Examination Survey (KNHANES). This cross-sectional study included parents of participants under 19 years of age (970 with atopic dermatitis and 5,733 without atopic dermatitis after excluding those who meet the exclusion criteria) from the 2009 to 2012 KNHANES.

Association between History of Pregnancy and Liver Fibrosis Using Fibrosis-4 Index in Korean Postmenopausal Women: A Nationwide Population-Based Study.

Background: The association between a history of pregnancy and liver fibrosis remains unclear. Herein, we investigated the association between reproductive factors, including a history of pregnancy and liver fibrosis, in postmenopausal Korean women.

Methods: This study used nationally representative, population-based data collected from the Korea National Health and Nutrition Examination Survey 2008-2017.

Analysis of Quality of Life and Mental Health in Patients With Atopic Dermatitis, Asthma and Allergic Rhinitis Using a Nation-wide Database, KNHANES VII.

Purpose: This study investigated mental health status and quality of life in allergic disease patients compared with non-allergic controls.

Methods: This study used nationwide, population-based, cross-sectional data from the Korean National Health and Nutrition Examination Survey from 2016 to 2018. The propensity matching score was used to balance age and sex distributions between the allergic disease groups and corresponding controls.

Association between toothbrushing and non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome. Periodontitis, as chronic inflammatory destructive disease, is associated metabolic syndromes bidirectionally. Toothbrushing is an essential and important way to manage periodontitis through mechanical removal of biofilm at periodontal tissue.

Association between cotinine-verified smoking status and moderately increased albuminuria in the middle-aged and older population in Korea: A nationwide population-based study.

Objectives: Although several self-reported questionnaire-based studies have found an association between smoking and moderately increased albuminuria, this result remains controversial. We investigated whether moderately increased albuminuria was associated with smoking status, verified by urinary cotinine (an objective biomarker of tobacco exposure), using population-based, nationally representative data.

Methods: This study included 2059 participants aged ≥ 50 years from the 2014 Korean National Health and Nutrition Examination Survey.

Association between Fatty Liver Index and Periodontitis: the Korea National Health and Nutrition Examination Survey.

It has been suggested that periodontitis is associated with metabolic abnormalities including non-alcoholic fatty liver disease (NAFLD). The fatty liver index (FLI) is a non-invasive surrogate marker and predictor of NAFLD. We aimed to determine whether FLI itself would be associated with periodontitis through a secondary analysis of previously reported nationally representative probability sample data of the Korean population.
