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. The data sources included statistics and reports from the World Health Organization (WHO) and the Organization for Economic Cooperation and Development (OECD), the Korea National Health and Nutrition Examination Survey, as well as various national statistics and reports on tobacco use and control in Korea.Over the past quarter-century, there was a notable 49.6% reduction in the prevalence of cigarette smoking among Korean adults, with a particularly pronounced decline among men (1998: 66.3% vs. 2022: 30.0%; a 54.8% decrease). However, the reduction among women was more modest, with only a 1.5 percentage point decrease (1998: 6.5% vs. 2022: 5.0%; a 23.1% decrease), and an increase in smoking prevalence was observed among women in their 20s and 30s. Overall use of any tobacco product, including cigarettes, heated tobacco products, electronic nicotine delivery systems, and others, was 6.6 percentage points higher among males and 2.2 percentage points higher among females compared to cigarette smoking alone.In 2019, there were 58,036 deaths attributed to direct smoking in Korea, with an estimated socioeconomic cost of smoking amounting to 12,191.3 billion Korean won. Furthermore, critical issues in tobacco use persist in Korea, including significant disparities in tobacco use related to age, gender, and disability, the growing use of novel tobacco and nicotine products among adolescents and younger adults, and regulatory blind spots. The reduction in smoking rates in Korea reflects the impact of expanded tobacco control policies and public health initiatives. However, for Korea to advance to the next level in tobacco control policies, it is essential to implement the WHO Framework Convention on Tobacco Control’s MPOWER measures more thoroughly.

The Korea National Disability Registration System (KNDRS) was established in 1989 to provide social welfare benefits based on predefined criteria for disability registration and an objective medical assessment using a disability grading system. Disability registration requires (1) a medical examination by a qualified specialist physician and (2) a medical advisory meeting to review the degree of disability. Medical institutions and specialists for the diagnosis of disabilities are legally stipulated, and medical records for a specified period are required to support the diagnosis. The number of disability types has gradually expanded, and 15 disability types have been legally defined. As of 2021, 2.645 million people were registered as disabled, accounting for approximately 5.1% of the total population. Among the 15 disability types, disabilities of the extremities account for the largest proportion (45.1%). Previous studies have investigated the epidemiology of disabilities using data from the KNDRS, combined predominantly with data from the National Health Insurance Research Database (NHIRD). Korea has a mandatory public health insurance system that covers the entire Korean population, and the National Health Insurance Services manages all eligibility information, including disability types and severity ratings. In short, the KNDRS-NHIRD is a significant data resource for research on the epidemiology of disabilities.

Background: Food insecurity may contribute to mental health indicators such as stress, anxiety, or depression. We investigated whether food insecurity was associated with mental health indicators and health-related quality of life (HRQoL) in a representative sample of the Korean population. Methods: This study enrolled 12,987 adults without a history of medically serious disease from the 2012, 2013, and 2015 Korea National Health and Nutrition Examination Survey. Household food security status was categorized as “food security,” “mild food insecurity,” and “moderate/severe food insecurity.” The association between mental health and HRQoL was evaluated using a multivariate logistic regression model with food security as the reference group. Results: The adjusted odds ratio of adverse mental health or low HRQoL increased significantly in mild or moderate/severe food insecurity compared to food security. In the moderate/severe food insecurity group, it was 1.98% (95% confidence interval [CI], 1.31– 2.99) higher for perceived stress, 3.58% (95% CI, 2.44–5.26) higher for depression symptoms, 4.16% (95% CI, 2.68–6.45) higher for suicidal ideation, and 2.81% (95% CI, 1.91–4.15) higher for quality of life. Conclusion Food insecurity was strongly associated with negative mental health status and poor HRQoL. There is a need for a dietary support program that provides psychosocial support to those experiencing food insecurity.

There are more than 1,000 million people with disability worldwide, about 15% of the global population. The prevalence of disability has been rising because of aging populations and the increase in people with chronic diseases. Even though it is well known that people with disability have an increased risk of chronic diseases and mortality at a younger age, health policies have not been developed correspondingly.Current Concepts: Disability epidemiology is a study of the patterns, distributions, determinants, and outcomes of disabling conditions. From the medical model perspective, people with disabilities are just ill or abnormal. To overcome the limitations of the medical model, the World Health Organization developed the International Classification of Functioning, Disability and Health.Discussion and Conclusion: Using the International Classification of Functioning, Disability and Health model based on a biopsychosocial framework, the healthcare community should work together to develop and implement action plans to improve the health of those with disabilities. These policies are essential to care for acute-stage disabilities, build an integrated care system, and provide a better environment for people with disability.

Purpose: Implementation of screening program may lead to increased health disparity within the population if participation differs by socioeconomic status. In Korea, colorectal cancer screening is provided at no or minimal cost to all people over 50 by National Cancer Screening Program. We investigated colorectal cancer screening participation rate and its trend over the last 10 years in relation to disabilities. Materials and Methods: We linked national disability registration data with National Cancer Screening Program data. Age, sex-standardized participation rates were analyzed by type and severity of disability for each year, and factors associated with colorectal cancer screening participation were examined by multivariate logistic regression. Results: Age, sex-standardized participation rate in people without disability increased from 16.2 to 33.9% (change, +17.7), but it increased from 12.7% to 27.2% (change, +14.5) among people with severe disability. People with severe disabilities showed a markedly lower colorectal cancer screening participation rate than people without disability (adjusted odds ratio [aOR], 0.714; 95% confidence interval, 0.713 to 0.720). People with autism (aOR, 0.468), renal failure (aOR, 0.498), brain injury (aOR, 0.581), ostomy (aOR, 0.602), and intellectual disability (aOR, 0.610) showed the lowest participation rates. Conclusion Despite the availability of a National Cancer Screening Program and overall increase of its usage in the Korean population, a significant disparity was found in colorectal cancer screening participation, especially in people with severe disabilities and or several specific types of disabilities. Greater effort is needed to identify the barriers faced by these particularly vulnerable groups and develop targeted interventions to reduce inequality.

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. Materials and Methods: Demographic, socioeconomic, and medical data were obtained from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claims database. An age- and sex-matched cohort was established using a 1:3 ratio constituted with 2,776,450 people with disabilities and 8,329,350 people without disabilities. Adult patients diagnosed with MM were subsequently selected from this cohort. Disabilities were categorized as physical, communication, intellectual or psychological, and affecting the major internal organs. Results: The cohort included 4,090 patients with MM, with a significantly lower rate per 100,000 persons among people with disabilities than among people without disabilities (29.1 vs. 39.4, p < 0.001). People with disabilities were more likely to undergo dialysis treatment at the time of diagnosis (16.3% vs. 10.0%, p < 0.001), but were less likely to undergo autologous stem cell transplantation (37.5% vs. 43.7%, p=0.072). This trend was more evident among patients with intellectual or psychological disabilities. The median overall survival among patients with disabilities was significantly shorter than that among patients without disabilities (36.8 months vs. 51.2 months, p < 0.001). Conclusion In Korea, people with disabilities generally have a lower rate of MM diagnosis, receive less intensive treatment, and have a lower survival rate than people without disabilities.

PURPOSE: Health-related quality of life (HRQOL) information related to radical prostatectomy (RP) is valuable for prostate cancer (PC) patients needing to make treatment decisions. We aimed to investigate HRQOL change in PC patients who underwent three types of RP (open, laparoscopic, or robotic) and compared their HRQOL with that of general population. MATERIALS AND METHODS: Patients were prospectively recruited between October 2014 and December 2015. European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire (EORTC QLQ-C30) and PC-specific module (PR25) were administered before surgery (baseline) and at postoperative 3 and 12 months. At each time point, HRQOL was compared, and a difference of 10 out of 0-100 scale was considered clinically significant. RESULTS: Among 258 screened patients, 209 (41 open, 63 laparoscopic, and 105 robotic surgeries) were included. Compared to baseline, physical, emotional, and cognitive functioning improved at 12 months. Role functioning worsened at 3 months, but recovered to baseline at 12 months. Pain, insomnia, diarrhea, and financial difficulties also significantly improved at 12 months. Most PR25 scales excluding bowel symptoms deteriorated at 3 months. Urinary symptoms and incontinence aid recovered at 12 months, whereas sexual activity and sexual function remained poor at 12 months. Clinically meaningful differences in HRQOL were not observed according to RP modalities. Compared to the general population, physical and role functioning were significantly lower at 3 months, but recovered by 12 months. Social functioning did not recover. CONCLUSION: Most HRQOL domains showed recovery within 12 months after RP, excluding sexual functioning and social functioning. Our findings may guide patients considering surgical treatment for PC.
