Abstract
OBJECTIVES
We examined the associations of socioeconomic factors, health behaviors, and comorbidities with early-onset lung cancer.
METHODS
The study included 6,794,287 individuals aged 20-39 years who participated in a Korean national health check-up program from 2009 to 2012. During the follow-up period, 4,684 participants developed lung cancer. Multivariable Cox regression analysis was used to estimate the independent associations of potential risk factors with incident lung cancer.
RESULTS
Older age (multivariable hazard ratio [mHR], 1.13; 95% confidence interval [CI], 1.12 to 1.14) and female sex (mHR, 1.62; 95% CI, 1.49 to 1.75) were associated with increased lung cancer risk. Current smoking was also associated with elevated risk (<10 pack-years: mHR, 1.12; 95% CI, 1.01 to 1.24; ≥10 pack-years: mHR, 1.30; 95% CI, 1.18 to 1.45), but past smoking was not. Although mild alcohol consumption (<10 g/day) was associated with lower lung cancer risk (mHR, 0.92; 95% CI, 0.86 to 0.99), heavier alcohol consumption (≥10 g/day) was not. Higher income (highest vs. lowest quartile: mHR, 0.86; 95% CI, 0.78 to 0.94), physical activity for at least 1,500 metabolic equivalent of task-min/wk (vs. non-exercisers: mHR, 0.83; 95% CI, 0.69 to 0.99) and obesity (vs. normal weight: mHR, 0.89; 95% CI, 0.83 to 0.96) were associated with lower lung cancer risk, whereas metabolic syndrome was associated with increased risk (mHR, 1.13; 95% CI, 1.03 to 1.24).
CONCLUSIONS
In young adults, age, female sex, smoking, and metabolic syndrome were risk factors for early-onset lung cancer, while high income, physical activity, and obesity displayed protective effects.
Summary
Korean summary
나이, 여성, 흡연, 그리고 대사 증후군은 조기 발생 폐암의 위험도 증가와 연관이 있었다. 반면에 높은 소득, 신체 활동, 비만은 젊은 성인에서 폐암 발생의 위험도 감소와 연관성을 나타내었다.
Key Message
Age, female sex, smoking, and metabolic syndrome were risk factors for early-onset lung cancer. While, high income, physical activity, and obesity displayed protective effects on the development of lung cancer in young adults.

Abstract
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.
Summary
Korean summary
한국에서는 장애의 유형과 장애 유형별 장애정도를 장애인 복지법에서 규정하고 있다. 우리는 한국의 장애등록제도의 역사와 장애등록절차 그리고 장애유형별 통계 현황에 대해서 다루고자 한다.
Key Message
In Korea, the types and severity levels of disabilities are legally defined by the Korea National Disability Registration System (KNDRS). We address the history of the KNDRS, disability registration procedures, and current statistics.
