Prevalence and correlates of prior experimentation with e-cigarettes over conventional cigarettes among adolescents: Findings from the 2015 Korea Youth Risk Behaviour Web-based Survey.

Introduction: As concern is increasing about electronic cigarette use among never-smoking youth, we aimed to examine the prevalence and correlates of prior experimentation of electronic cigarettes (e-cigs) over conventional cigarettes (c-cigs).

Methods: We used the 10th Korea Youth Risk Behavior Web-based Survey in 2015, including 67960 participants as study subjects. This survey was designed as stratified multistage clustered samples from middle schools and high schools.

Anemia is associated with incidence of dementia: a national health screening study in Korea involving 37,900 persons.

Background: The aim of this study was to investigate whether anemia is associated with dementia incidence in the elderly.

Methods: Using the Korean National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS) database, we identified 66-year-old subjects (n = 37,900) who were free of dementia and stroke. Anemia (hemoglobin < 12 g/dl for women and < 13 g/dl for men) and the severity of anemia (mild, moderate, or severe) were defined using World Health Organization criteria.

Relationship between bone mineral density and alcohol consumption in Korean men: the Fourth Korea National Health and Nutrition Examination Survey (KNHANES), 2008-2009.

Background And Objectives: Drinking is a risk factor of osteoporosis, but controversy surrounds the relationship between alcohol consumption and bone mineral density (BMD). We performed an analysis of the association between alcohol consumption and BMD.

Methods And Study Design: A cross-sectional study was performed including 2421 men, aged 40-93 years, who participated in the fourth Korea National Health and Nutrition Examination Survey in 2008-2009.

Helicobacter pylori: A Possible Risk Factor for Bone Health.

Background: Helicobacter pylori (H. pylori) infection may cause systemic inflammation and increase the production of tumor necrosis factor-α, interleukin-1, and interleukin-6. Unfortunately, bone mineral density also may be affected by these cytokines.

Association between nutrition label use and chronic disease in Korean adults: the Fourth Korea National Health and Nutrition Examination Survey 2008-2009.

Nutrition labels are helpful for chronic disease management in patients requiring balanced nutritional intake. This study aimed to investigate the association between the use of nutrition labels and chronic diseases (hypertension, diabetes mellitus, and hyperlipidemia) by using the 2008-2009 Korea National Health and Nutrition Examination Survey data. A total of 10,695 individuals aged 20 and over was included in the analysis.
