Abstract
The Korea Nurses’ Health Study (KNHS) is an ongoing, large-scale, prospective cohort study of women nurses, focusing on the effects of occupational, environmental, and lifestyle factors on the health of women. The first KNHS survey was performed in 2013-2014 (n=20,613). As of December 2023, 11 follow-up surveys have been conducted. Participants who were pregnant were asked to participate in the early pregnancy survey (n=2,179) and postpartum survey after giving birth (n=2,790). The main variables included socio-demographic, work-related, lifestyle, physical, mental, and women’s health factors. Blood, urine, and toenail samples were collected from a participant subgroup of the first survey (n=1,983). The subgroups of the second survey completed a food frequency questionnaire in 2019 (n=300) and 2021 (n=871). In 2020, a subgroup of the first survey answered a coronavirus disease 2019-related survey (n=975). To examine various health-related factors in young adults, new participants were added to the KNHS cohort in the 11th (n=1,000) and 12th (n=1,002) surveys. The KNHS cohort will help identify health and illness determinants in Korean women. Data can be accessed at https://coda.nih.go.kr/frt/index.do.

한국간호사건강연구(Korea Nurses’ Health Study, KNHS)는 2013년부터 수행되고 있는 대규모 전향적 추적관찰 코호트 연구이다. 본 연구는 질병력, 약물복용력, 임신력, 여성건강, 정신건강(우울, 스트레스, 피로 등), 생활습관(흡연, 음주, 신체활동, 수면 등), 근무특성을 조사하여 여성건강에 장기적으로 미치는 영향을 파악하고 한국 고유의 여성건강 결정요인을 도출하는 것을 목표로 한다.
Key Message
The Korea Nurses' Health Study (KNHS) is a large-scale, prospective cohort study that has been conducted since 2013. It measures various factors affecting reproductive-aged women, including disease history, medication usage, pregnancy, women's health characteristic, mental health (such as depression, stress, and fatigue), lifestyle characteristic (including smoking, drinking, and physical activity, sleep), and work-related characteristics. The study aims to understand the long-term impact on women's health and identify unique determinants of women's health specific to Korea.

Abstract
OBJECTIVES
Previous studies have shown that people with multimorbidity have a higher risk of depression than those without multimorbidity. However, few studies have examined the association between depression and multimorbidity in men and women separately. Since the rates of depression and multimorbidity are different in men and women, it is necessary to examine whether gender differences affect their association.
METHODS
This study included 30,138 participants (aged ≥ 65 years) from the National Survey of Older Koreans (2011-2017). Depression was defined using the Korean version of the Geriatric Depression Scale (SGDS-K). Multimorbidity was defined as people who had 2 or more chronic diseases, including arthritis, diabetes, heart disease, hypertension, pulmonary disease, cancer, stroke, or osteoporosis. Multiple logistic regression analysis was performed to determine the association between depression and multimorbidity.
RESULTS
In total, 22.2% and 30.7% of men and women, respectively, had depression. Those with multimorbidity had a higher risk of depression than those without chronic conditions; specifically, the difference in risk among men was greater than that among women. Age was considered a moderator for women. While the effects of pulmonary disease, stroke, and cancer were especially substantial in the integrated analysis, gender differences were observed related to various chronic conditions comorbid with heart disease.
CONCLUSIONS
There are gender differences in the association between multimorbidity and depression among older Korean adults. Therefore, gender-specific care should be provided to reduce depression in older adults with multimorbidity.

복합만성질환을 가진 남성 노인이 복합만성질환을 가진 여성 노인보다 우울증을 경험할 위험이 높았다. 특히 심장질환을 가진 남성 노인과 여성 노인은 심장질환을 포함한 만성질환의 개수에 따라 우울증 위험에 차이가 있었다. 노인들의 수명 향상을 위해 성별 차이를 고려한 치료 방안과 정책이 마련되어야 한다.
Key Message
Multimorbidity was associated with a high-risk of depression in older Korean adults and the effects of multimorbidity differed by gender.

Abstract
Radon is a naturally occurring radioactive material formed by the slow decay of uranium and thorium found in the earth’s crust or construction materials. Internal exposure to radon accounts for about half of the natural background radiation dose to which humans are exposed annually. Radon is a carcinogen and is the second leading cause of lung cancer following smoking. An association between radon and lung cancer has been consistently reported in epidemiological studies on mine workers and the general population with indoor radon exposure. However, associations have not been clearly established between radon and other diseases, such as leukemia and thyroid cancer. Radiation doses are assessed by applying specific dose conversion coefficients according to the source (e.g., radon or thoron) and form of exposure (e.g., internal or external). However, regardless of the source or form of exposure, the effects of a given estimated dose on human health are identical, assuming that individuals have the same sensitivity to radiation. Recently, radiation exceeding the annual dose limit of the general population (1 mSv/yr) was detected in bed mattresses produced by D company due to the use of a monazite-based anion powder containing uranium and thorium. This has sparked concerns about the health hazards for mattress users caused by radiation exposure. In light of this event, this study presents scientific information about the assessment of radon and thoron exposure and its human implications for human health, which have emerged as a recent topic of interest and debate in society.

라돈은 세계보건기구에서 지정한 발암물질로, 흡연 다음으로 폐암을 유발한다. 지난 2018년 5월에 D사 침대 매트리스에서 라돈 및 토론에 의한 일반인의 선량한도 기준치(1 mSv/yr) 이상의 방사선이 검출되었다. 이로 인해 침대 사용자의 방사선 피폭으로 인한 건강영향 우려가 대두되고 있다. 이번 연구에서는 라돈 침대 노출 사고와 관련하여 그 동안 잘 알려지지 않은 라돈 및 토론의 노출평가 및 역학 연구 결과들을 살펴보고, 그 시사점을 고찰한다.
