Tobacco Use in Korea: Current Epidemiology and Public Health Issues.

Tobacco control efforts in Korea began nearly three decades ago with the enactment of the National Health Promotion Act in 1995. Monitoring smoking prevalence is crucial for evaluating the effectiveness of tobacco control measures, as reductions in smoking rates reflect the impact of anti-smoking policies. This review aims to provide an updated overview of the epidemiology of tobacco use in Korea, outline the nation's advancements in tobacco control, and emphasize emerging challenges in tobacco use.

Longitudinal analysis of anxiety and sleep disorders in the Korean population with disabilities, from 2006 to 2017: Incidence, prevalence, and association with disability type and severity.

Background: Individuals with disabilities often face a higher risk of concurrent psychological problems, yet comprehensive assessments of the anxiety and sleep disorders in this population remain limited. This study examined longitudinal trends in the incidence and prevalence of anxiety and sleep disorders among people with disabilities and explored their associations with disability type and severity.

Methods: Utilizing claim data from the National Health Insurance database and the National Disability Registry, which cover the entire Korean population, we estimated the age-standardized incidence and prevalence of anxiety and sleep disorders between 2006 and 2017.

Nationwide prevalence and trends in cigarette smoking among adult men with and without disabilities in South Korea between 2009 and 2017.

Objectives: Current smoking rates for people with and without disabilities vary among countries. This study analyzed smoking behavior over 9 years in adult South Korean men with disabilities, according to disability severity and type, and in those without disabilities.

Study Design: This was a cross-sectional study.

Disparities in the Diagnosis and Treatment of Bile Duct Cancer in People with Disabilities: A National Cohort Study in South Korea.

We aimed to evaluate the impacts of disability on the diagnosis, treatment, and prognosis of bile duct cancer (BDC) according to the severity and type of disability. Patients diagnosed with BDC were selected from an age- and sex-matched population (1:3 ratio) with or without disabilities from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claims database. The cohort included 15,065 patients with BDC, with a significantly lower rate in those with severe disabilities than in people without or with mild disabilities (110.

Impact of hospital volume on people with disability and outcomes for cancer surgery.

Background: This study was performed to examine the association between hospital volume and mortality in people with disability.

Methods: A retrospective cohort study was conducted using a data set linking the Korean National Health Service database, disability registration data, and Korean Central Cancer Registry data. Data was gathered from all patients undergoing the four major surgical procedures for cancer care during an 11-year period from 2003 to 2013.

Complicated Appendicitis Among Adults With and Without Disabilities: A Cross-Sectional Nationwide Study in South Korea.

Objective: Appendicitis is usually diagnosed based on a reliable set of signs and symptoms, and can be effectively treated with surgery, with low morbidity and mortality rates. However, appendicitis is often overlooked in vulnerable populations, including people with disabilities. This study compared 10-year trends of complicated appendicitis between South Koreans with a disability, according to disability severity and type, and those without disabilities.

U-shaped association between body mass index and health-related quality of life impairment in Korean cancer survivors: a nationwide representative cross-sectional survey.

Purpose: Although obesity is an important risk factor for cancer incidence, the effect of body mass index (BMI) on health-related quality of life (HRQoL) after cancer treatment remains unknown. This population-based cross-sectional study assessed different levels of BMI as an important factor associated with impaired HRQoL in long-term cancer survivors.

Methods: The study enrolled 1104 cancer survivors from the fourth to seventh Korea National Health and Nutrition Examination Surveys (KNHANES 2007-2018) who were alive at least 5 years after their cancer diagnoses.

Disparities in the Diagnosis, Treatment, and Survival Rate of Cervical Cancer among Women with and without Disabilities.

Introduction: Not much is known regarding the disparities in cancer care between women with and without disabilities.

Objectives: The aim of this study was to investigate the potential disparities in the diagnosis, treatment, and survival of women with cervical cancer with and without disabilities.

Methods: We performed a retrospective cohort study and linked the National Disability Database, Korean Central Cancer Registry, and Korean National Health Insurance claims database.

Disparities in prostate cancer diagnosis, treatment, and survival among men with disabilities: Retrospective cohort study in South Korea.

Background: Disparities in cancer care have not been well documented for individuals with disability.

Objective: To investigate potential disparities in the diagnosis, treatment, and survival of prostate cancer (PC) patients according to disability status.

Methods: A retrospective cohort study using disability registration data linked to Korean National Health Insurance and national cancer registry data.

Disparities in the Diagnosis and Treatment of Gastric Cancer in Relation to Disabilities.

Introduction: We investigated potential disparities in the diagnosis, treatment, and survival of gastric cancer (GC) patients with and without disabilities.

Methods: We linked Korean National Disability Registry data with the Korean National Health Insurance database and Korean Central Cancer Registry data. This study included a total of 16,849 people with disabilities and 58,872 age- and sex-matched control subjects in whom GC had been diagnosed.

Differences in diagnosis, treatment, and survival rate of acute myeloid leukemia with or without disabilities: A national cohort study in the Republic of Korea.

We analyzed the patterns of diagnosis, treatment, and prognoses of acute myeloid leukemia (AML) patients with and without disabilities. The data were collected from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claim database. We built a cohort of 2 776 450 people with disabilities and a nondisabled cohort of 8 329 350 people who were selected at a ratio of 1:3 by matching age and sex.

Burnout Among oncologists in the Republic of Korea: A nationwide survey.

Purpose: Burnout in oncologists negatively impacts patient care and health care system, as it is associated with poor patient satisfaction, medical errors, leaving current practice, and/or early retirement. Because the quality of life of oncologists is influenced by various factors and ultimately affects the patient's treatment and medical system, we aimed to investigate burnout among oncologists and to identify factors affecting burnout.

Materials And Methods: A total of 130 oncologists recruited from 13 cancer centers participated in a nationwide survey.

Breast cancer screening disparities between women with and without disabilities: A national database study in South Korea.

Background: Health disparities among individuals with disabilities remain underrecognized. The objective of the current study was to investigate: 1) whether disparities exist in breast cancer screening rates among women with disabilities compared with women without disabilities; 2) whether breast cancer screening rates vary according to the type and severity of disabilities; and 3) trends in breast cancer screening disparities according to disability status over time.

Methods: Using national administrative databases concerning disability status and national cancer screening programs in Korea, age-standardized participation rates were calculated according to the type and severity of disabilities.

The Effect of Disability on the Diagnosis and Treatment of Multiple Myeloma in Korea: A National Cohort Study.

Purpose: This study aimed to determine whether the diagnosis, treatment approach, and prognosis of multiple myeloma (MM) vary according to the presence and type of disability.
