PURPOSE: Although many studies have demonstrated that smoking, alcohol, obesity, and insulin resistance are risk factors for cancer, the role of those factors on cancer survival has been less studied. PATIENTS AND METHODS: The study participants were 14,578 men with a first cancer derived from a cohort of 901,979 male government employees and teachers who participated in a national health examination program in 1996. We obtained mortality data for those years from the Korean Statistical Office.

Among Korean young adults, stage 1 and stage 2 hypertension, compared with normal blood pressure, were associated with increased risk of subsequent cardiovascular disease events. Young adults with hypertension, defined by the 2017 ACC/AHA criteria, may be at increased risk of cardiovascular disease.

Residing in urban regions with greater green space coverage may lead to a reduced risk of CVD. Urban planning intervention policies that increase urban green space coverage could help to reduce the risk of CVD.

In this nationally representative study, we found that obesity was associated with lower risk of cognitive decline among mid- and old-age population.

BACKGROUND: Anemia is thought to increase mortality risks, but the effects of high hemoglobin concentration on survival are unclear. The effect of change in hemoglobin concentrations on survival in the general population is also unknown. This study aimed to examine the effect of hemoglobin concentrations and their changes on cardiovascular and all-cause mortality risks. METHODS AND RESULTS: We retrospectively analyzed a cohort from the NHIS-HEALS (National Health Insurance Service-National Healt

Relationship of muscle mass and fat mass with insulin resistance and metabolic syndrome remains uncertain, especially among Asian population. We performed a cross-sectional study with 14,807 adult participants aged between 18 and 65 in the fourth and fifth Korea National Health and Nutrition Examination Survey with Dual Energy X-ray Absorptiometry (DEXA) data to investigate whether muscle mass and fat mass are associated with insulin resistance and metabolic syndrome. DEXA records were used to c

OBJECTIVE: To determine the risk of developing dementia in relation to duration of smoking cessation by using a nationwide health claims database. METHODS: This cohort study included 46,140 men aged 60 years or older from Korean National Health Insurance System - National Health Screening Cohort, a population-based national health screening program from 2002 to 2013. The changes in smoking habit from a questionnaire during the first (2002 and 2003) and second (2004 and 2005) health examination p

OBJECTIVES: Although chronic periodontitis has been associated with Alzheimer's disease, the effect of chronic periodontitis on vascular dementia as well as the role of lifestyle behaviors such as smoking, alcohol consumption, and physical activity in this association are still unclear. DESIGN: Retrospective cohort study. SETTING: Population based. PARTICIPANTS: The study population was derived from the Korean National Health Insurance Service-Health Screening Cohort. Among 262 349 participants,

AIMS: Little is known about the trade-off between the health benefits of physical activity (PA) and the potential harmful effects of increased exposure to air pollution during outdoor PA. We examined the association of the combined effects of air pollution and changes in PA with cardiovascular disease (CVD) in young adults. METHODS AND RESULTS: This nationwide cohort study included 1 469 972 young adults aged 20-39 years. Air pollution exposure was estimated by the annual average cumulative leve

Previous studies have reported inconsistent findings regarding the association between the use of selective serotonin reuptake inhibitors (SSRIs) and the risk of fracture. We identified relevant studies by searching three electronic databases (MEDLINE, EMBASE, and the Cochrane Library) from their inception to October 20, 2010. Two evaluators independently extracted data. Because of heterogeneity, we used random-effects meta-analysis to obtain pooled estimates of effect. We identified 12 studies:

Obesity and weight gain were associated with elevated risk of CHD among young adults in this study. Studies that prospectively determine the association between weight change and CHD risk are needed to validate these findings.

PURPOSE: Smoking, obesity, and insulin resistance are well-known risk factors for cancer, yet few epidemiology studies evaluate their role as risk factors for a second primary cancer (SPC). PATIENTS AND METHODS: We identified 14,181 men with a first cancer from the National Health Insurance Corporation Study cohort. We obtained data on fasting glucose level, body mass index (BMI), and smoking history from an enrollment interview (1996). We obtained SPC incidence data for 1996 through 2002 from t
