Abstract
OBJECTIVES
Mushrooms, known for their nutritious and functional components, are considered healthy and medicinal. This study investigated the prospective association between dietary mushroom consumption and the incidence of type 2 diabetes among Korean adults aged ≥ 40 years.
METHODS
In total, 16,666 participants who were not taking anti-diabetic medication or insulin and had normal fasting blood glucose (FBG) (< 126 mg/dL) were included. We used the cumulative average dietary consumption of mushrooms as an exposure metric, calculated from food frequency questionnaires at every follow-up, along with covariates collected during a baseline survey. To estimate incidence rate ratios (IRRs) for type 2 diabetes, a modified Poisson regression model with a robust error estimator was applied.
RESULTS
In multivariable models, dietary mushroom consumption was inversely associated with type 2 diabetes incidence in both sexes (men: IRR, 0.65; 95% CI, 0.47 to 0.90; plinearity = 0.0427 in the highest quartile (Q4) vs. the lowest quartile (Q1); women: IRR, 0.70; 95% CI, 0.54 to 0.93; plinearity = 0.1145 in Q4 vs. Q1). The inverse association remained after adjustment for dietary factors instead of dietary quality index, the baseline FBG, and the exclusion of incidence within the first year. Additionally, no significant interaction was found regarding the risk of type 2 diabetes between dietary mushroom consumption and participants’ sex or other factors.
CONCLUSIONS
Dietary mushroom consumption was inversely linked with the risk of type 2 diabetes incidence in both sexes, indicating the beneficial role of mushrooms in preventing the disease.

Abstract
OBJECTIVES
Limited and inconsistent prospective evidence exists regarding the relationship of dietary total antioxidant capacity (dTAC) and antioxidant intake with metabolic syndrome (MetS) risk. We evaluated the associations of the cumulative averages of dTAC and antioxidant intake (in 5 classes: retinol, vitamin C, vitamin E, carotenoids, and flavonoids, as well as 7 flavonoid subclasses) with the risk of MetS.
METHODS
This study included 11,379 participants without MetS, drawn from the Korean Genome and Epidemiology Study_CArdioVascular disease Association Study (KoGES_CAVAS). The cumulative average consumption was calculated using repeated food frequency questionnaires. Incidence rate ratios were estimated using a modified Poisson regression model with a robust error estimator.
RESULTS
The median follow-up period was 5.16 years, and 2,416 cases of MetS were recorded over 58,750 person-years. In men, significant inverse associations were observed in all 5 antioxidant classes, except for the highest quartile of dTAC. In women, dTAC and total flavonoids were not significantly associated with MetS; however, significant L-shaped associations were found for the remaining 4 antioxidant classes. Of the 7 flavonoid subclasses, only flavones in the highest quartile for men and flavan-3-ols in women lacked significant associations with MetS. The inverse associations were not sex-specific, but they were particularly pronounced among participants with a body mass index (BMI) of 23 kg/m<sup>2</sup> or higher.
CONCLUSIONS
The findings suggest that most antioxidant classes and flavonoid subclasses, unlike dTAC, exhibit a clear beneficial association with MetS in an L-shaped pattern in both men and women, particularly those with a high BMI.
Summary
Korean summary
농촌코호트 조사 참여자를 대상으로 식이 총항산화능, 총항산화능 하위분류, 플라보노이드 하위분류와 대사증후군 발생 위험의 전향적 연관성을 평가한 결과, 대부분의 항산화물(5개항산화물 분류:4개 항산화 비타민과 플라보노이드; 플라보노이드 7개 하부분류)에서 대사증후군과 음의 상관성을 확인할 수 있었으며 총항산화능(남자와 여자)과 플라보노이드(여자)에서 약한 연관성을 보였다. 남녀간 유의한 상호작용은 없었고 특히 BMI가 높은 집단에서 두드러졌다. 이 연구의 결과는 특히 식이 총항산화능을 구성하는 하위 유형을 적절히 섭취하는 것이 특히 비만한 성인에서 대사증후군 위험을 낮추는 예방전략으로 효과가 있을 수 있음을 시사한다.
Key Message
We observed that the cumulative average of dietary antioxidant vitamins and most flavonoids may be have pivotal roles in prevention of MetS, although there may be weak associations of dTAC and flavonoids in women. Moreover, these inverse associations were more pronounced in high BMI individuals. Our results suggest that the consumption of antioxidants and flavonoid may mitigate the MetS risk, particularly in overweight/obese individuals at high risk of developing chronic diseases.

Abstract
OBJECTIVES
We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea.
METHODS
In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022.
RESULTS
In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%.
CONCLUSIONS
The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

인구집단을 기반으로 하여 대표성 있는 표본을 추출하여 COVID-19 항체유병률 조사를 전국적으로 수행함으로 지역사회 단위에서 지속적으로 모니터링할 수 있는 COVID-19 감시체계 구축의 기반을 마련하였다. 2022년 8월 우리나라 국민의 대부분이 COVID-19에 대한 항체를 보유하고 있었고 인구 3명 중 1명은 미확진 감염자로 추정되었다.
Key Message
The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19. In August 2022, most of the Korean people had antibodies to COVID-19, and one in three people was estimated to have an unreported infection. This study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

Abstract
The number of persons infected by HIV/AIDS has consistently increased in Korea since the first case of HIV/AIDS infection in 1985 and reached 15,208 by 2016. About 1,100 new patients with HIV/ AIDS infections have emerged every year since 2013. In Korea, the Korea HIV/AIDS Cohort Study was established for the evidenced-based prevention, treatment, and effective management of patients infected with human immunodeficiency virus (HIV) in December 2006. This study monitored 1,438 patients, who accounted for about 10% of all patients with HIV/AIDS in Korea, for 10 years with the following aims: (1) to develop an administrative system for the establishment of a HIV/AIDS cohort-based study; (2) to standardize methodologies and the case report forms; and (3) to standardize multi-cohort data and develop a data cleaning method. This study aims to monitor at least 1,000 patients (excluding those for whom investigation had been completed) per year (estimated number of patients who can be monitored by January 2018: 939). By December 2016, the sex distribution was 93.3% for men, and 6.7% for women (gender ratio, 13.9:1.0), and 98.9% of all participants were Korean. More than 50.0% of the participants were confirmed as HIV positive after 2006. This study reports competitive, long-term research that aimed to develop policies for the prevention of chronic infectious diseases for patients with HIV. The data collected over the last decade will be used to develop indices for HIV treatment and health promotion.
