Abstract
OBJECTIVES
Elevated serum triglyceride levels are a risk factor for developing cardiovascular disease. A number of studies have demonstrated a positive association between psychological stress and serum triglyceride levels. However, there is limited evidence regarding the impact of stressful life events (SLEs) on serum triglyceride levels in the healthy population. Therefore, we evaluated the independent association between SLEs and serum triglyceride levels in a middle-aged Korean population.
METHODS
We analyzed a sample of 2,963 people (aged 30-64 years; 36% men) using baseline data from the Cardiovascular and Metabolic Diseases Etiology Research Center (CMERC) cohort study. The Korean version of the Life Experience Survey questionnaire was used to measure the presence and positive/negative impact of SLEs. Hypertriglyceridemia was defined as a fasting serum triglyceride level of ≥ 150 mg/dL.
RESULTS
Of the 2,963 participants, 33.1% reported at least 1 SLE over the past 6 months and 24.8% had hypertriglyceridemia. Even after adjusting for potential confounders, the serum triglyceride level was significantly associated with the total number of SLEs in men (3.333 mg/dL per event; p= 0.001), but not in women (0.451 mg/dL per event, p= 0.338). Hypertriglyceridemia was also associated with having 4 or more SLEs with positive effects (odds ratio [OR], 2.57; 95% CI, 1.02 to 6.46) and 4 or more SLEs with negative effects (OR, 1.99; 95% CI, 1.16 to 3.41) in men.
CONCLUSIONS
Our findings suggest that SLEs may increase the risk of hypertriglyceridemia in middle-aged men.
Summary
Korean summary
30-64세 중년 남성에서 스트레스성 생활 사건(stressful life events)를 많이 경험한 경우 혈청 중성지방 농도가 높은 경향이 관찰되었다. 스트레스성 질환의 적절한 관리가 이상지질혈증같은 만성대사질환 예방에 도움이 될 수 있음을 시사하는 결과이다.
Key Message
Stressful life events can be linked to hypertriglyceridemia among middle-aged men. This suggests that proper management of stressful events can help prevention of metabolic disorders such as abnormal blood lipids.

Abstract
OBJECTIVES
This study aimed to identify relapse patterns in smokers who participated in an inpatient treatment program and to investigate factors related to relapse.
METHODS
The participants comprised 463 smokers who participated in an inpatient treatment operated by the Daejeon Tobacco Control Center from 2015 to 2018. Participants received high-intensity smoking cessation intervention for 5 consecutive days, including pharmacotherapy and behavioral support, and continued with follow-up for 1 year to determine whether they maintained smoking cessation after discharge from inpatient treatment. Kaplan-Meier and Cox proportional hazard models were used in the analysis.
RESULTS
Participants’ relapse rate within 1 year was 72.8%, and 59.8% of participants smoked again within 6 months after participation. A higher number of counseling sessions was significantly associated with a lower risk of relapse (hazard ratio [HR], 0.23; 95% confidence interval [CI], 0.17 to 0.32 for ≥9 vs. ≤5 counseling sessions). Conversely, higher relapse rates were significantly associated with the use of nicotine replacement therapy (NRT) (HR, 1.91; 95% CI, 1.43 to 2.55 for use vs. no use), and higher levels of baseline expired carbon monoxide (CO) (HR, 1.58; 95% CI, 1.21 to 2.06 for expired CO concentrations of 10-19 ppm vs. expired CO concentrations <10 ppm).
CONCLUSIONS
High-intensity smoking cessation interventions in hospital settings can be effective for smoking cessation in smokers with high nicotine dependence. In addition, the results suggest that for quitters to maintain long-term abstinence, they should receive regular follow-up counseling for 1 year after completing a high-intensity smoking cessation intervention.

Abstract
OBJECTIVES
Both cardiovascular health (CVH) and inflammation are associated with cognition, and inflammation is also associated with CVH. However, limited information has been reported on these factors in the Korean population. The objective of our study was to investigate the influence of inflammation on the association between CVH and cognition using a cross-sectional design.
METHODS
Data were obtained from the Cardiovascular and Metabolic Diseases Etiology Research Center baseline study. Participants who completed fasting serum analysis, questionnaires, and cognitive function tests were included in the analysis, whereas those with a history of autoimmune disease were excluded. The CVH in Ambulatory Care Research Team health index metrics, including smoking, physical activity, healthy diet, obesity, history of hypertension, and diabetes, were used to assess CVH. Cognitive function was evaluated with the Korean version of the Mini-Mental State Estimation for Dementia Screening. Inflammatory status was assessed based on a high-sensitivity C-reactive protein (hs-CRP) test.
RESULTS
Among 2,622 total participants (mean age, 57.2 years; 1,792 women), 13%, 58%, and 29% had poor, intermediate, and ideal CVH, respectively. Logistic regression analysis demonstrated that CVH was significantly associated with cognitive function only in women. A stratified analysis showed that cognitive impairment due to CVH was not associated with hs-CRP levels. When the same analyses were conducted for each CVH component, the only component affecting the association was hypertension history in men.
CONCLUSIONS
CVH is not significantly associated with cognitive decline in the middle-aged Korean population. Inflammation did not play a significant modifying role in this relationship.

Key Message
In the Korean middle-aged population, poor cardiovascular health (CVH) assessed by CANHEART health index was associated with low cognitive function, but not statistically significant. Further investigation is suggested to develop CVH index specified in Korean populations and to estimate the association between CVH and cognitive function in larger population.

Abstract
OBJECTIVES
Tobacco smoking is classified as carcinogenic to humans (International Agency for Research on Cancer Group 1). We aimed to estimate the percentage and number of incident cancer cases diagnosed in Texas in 2015 that were attributable to tobacco smoking, and we examined differences in the proportions of smoking-attributable cancers between the major racial/ethnic subgroups of the population.
METHODS
We calculated population-attributable fractions for cancers attributable to tobacco smoking using prevalence data from the Texas Behavioral Risk Factor Surveillance System and relative risks associated with smoking status from pooled analyses of cohort studies or meta-analyses. Cancer incidence data were collected from the Texas Cancer Registry.
RESULTS
We estimated that 19,000 excess cancer cases or 18.4% of all cancers diagnosed in 2015 in Texans aged ≥ 25 years were caused by tobacco smoking. Males had a higher overall proportion of cancers attributable to tobacco smoking than females (male, 23.3%, 11,993 excess cases; female, 13.5%, 7,006 cases). Approximately 20% of cancer cases in non-Hispanic Whites and non-Hispanic Blacks were attributable to tobacco smoking compared to 12.8% among Hispanics.
CONCLUSIONS
Despite ongoing public health campaigns combatting tobacco use, this preventable behavior still contributes significantly to cancer incidence in Texas. Racial/ethnic differences in smoking prevalence and smoking-attributable cancer incidence should be considered when designing cancer prevention programs.
Summary
Key Message
Tobacco smoking remains a major contributor to cancer burden in the United States, particularly among men, non-Hispanic whites and non-Hispanic Blacks due to historically higher smoking rates.

Abstract
OBJECTIVES
The association between obesity parameters and lung function indicators in the general Chinese rural adult population remains unclear.
METHODS
In total, 8,284 Chinese adults aged 20 years to 80 years old from Xinxiang were recruited. Obesity-related parameters, including body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), waistto-height ratio (WHtR), body fat percentage (BFP), basal metabolism, and visceral fat index, and lung function parameters such as forced vital capacity and forced expiratory volume in first second were measured.
RESULTS
The total prevalence of obesity defined by BMI, WC, WHR, WHtR, and BFP was 23.2%, 58.2%, 66.7%, 69.2%, and 56.5%, respectively. Spearman correlation analyses showed significant correlations between all obesity-related parameters and lung function. Linear regression analyses further demonstrated that BMI, WHtR, BFP, and general obesity defined using those indicators were negatively associated with lung function, while WC, WHR, and central obesity defined accordingly were positively associated with lung function. The relationship between general obesity and lung function was more evident in women than in men, while the link between central obesity and lung function was more obvious in men than in women.
CONCLUSIONS
Obesity is closely related to lung function in the general Chinese adult population. Weight control and loss are important strategies to improve lung function and respiratory health.
Summary
Key Message
This cross-sectional sduty clarify the relationship between several obesity parameters and lung function indicators on rural adult population in central China using big data and stratified analyses. Specifically, the obesity group has a lower level of lung function than the non-obesity group, and there is an opposite effect of general obesity and central obesity on lung function.

Abstract
OBJECTIVES
Diabetes is a well-known risk factor for atherosclerosis, but the association between a family history of diabetes and atherosclerosis remains unknown. In this study, we assessed the association between a family history of diabetes and increased carotid intima-media thickness (IMT), a marker of subclinical atherosclerosis, in a middle-aged Korean population.
METHODS
This cross-sectional study included 3,974 community-dwelling adults (1,404 male and 2,570 female) aged 30-64 years from the Cardiovascular and Metabolic Diseases Etiology Research Center cohort. The presence of a family history of diabetes was assessed through face-to-face interviews using a standardized questionnaire. Carotid IMT was assessed using B-mode ultrasonography, and increased IMT was defined as a value in the top quartile of the IMT values of all participants. Multivariate logistic regression was used to evaluate independent associations between a family history of diabetes and increased IMT.
RESULTS
A family history of diabetes was significantly associated with increased carotid IMT (odds ratio, 1.23; 95% confidence interval, 1.03 to 1.48) after adjusting for sex; age; body mass index; systolic blood pressure; total cholesterol, triglyceride, and hemoglobin A1c levels; smoking; alcohol consumption; exercise; use of antidiabetic, antihypertensive, and antilipidemic drugs; and a family history of hypertension. The positive association remained significant after excluding participants with diabetes (odds ratio, 1.21; 95% confidence interval, 1.00 to 1.47).
CONCLUSIONS
A family history of diabetes was positively associated with increased carotid IMT, even in participants without diabetes. Therefore, information on a family history of diabetes may help identify individuals at high risk of atherosclerotic cardiovascular disease.

Key Message
The family history of diabetes was positively associated with an increase in intima-media thickness of the carotid artery, even among people with normal fasting glucose levels. This suggests that asking for a family history of diabetes can help identify people at high risk of arteriosclerotic cardiovascular disease.

Abstract
OBJECTIVES
This study evaluated the effectiveness of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) as mouthwash and nasal spray on symptom relief in coronavirus disease 2019 (COVID-19) patients.
METHODS
Patients positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), who were treated in a hospital or at home, and patients’ family members (not positive for SARS-CoV-2), were randomized into 2 groups: experimental (1% H<sub>2</sub>O<sub>2</sub> for gargling, 0.5% H<sub>2</sub>O<sub>2</sub> for nasal wash), and control. Patients gargled the solution 3 times a day, and applied the nasal spray twice a day, for a 7-day period. Family members received the same treatment as the treated COVID-19 patient. The researchers contacted patients every 2 days over an 8-day period. An average post-treatment interval of 8 days passed before testing family members.
RESULTS
The most frequent symptoms on day 0 were cough, loss of taste, and hyposmia; there were no significant differences between groups, independent of the period. The symptom of dyspnea presented a significant difference between days 2 and 4 (p<0.05). Among family members, 86.0% had no antibodies, 2.3% had antibodies, and 11.6% had active infections (4 in the experimental group and 6 in the control group). The most frequent adverse effects in the H<sub>2</sub>O<sub>2</sub> group were a burning throat and nose.
CONCLUSIONS
H<sub>2</sub>O<sub>2</sub> was not effective for the relief of COVID-19 symptoms and was associated with reports of transient adverse effects.
Summary
Key Message
The hydrogen peroxide (H2O2) at low concentrations disrupts the lipid membranes of some viruses through the action of oxygen free radicals. Nevertheless, the data obtained in the present study demonstrated that the use of the H2O2 as mouthwash and nasal spray was not effective on symptom relief in patients with COVID-19. Moreover, it was associated with transient adverse effects such as burning sensations in the nose and throat. Thus, the authors of this study advise against the use of H2O2 as a mouthwash and nasal spray to relieve COVID-19 symptoms and transmission.

Abstract
OBJECTIVES
This study explored the effect of employment status on mortality over a 13-year period in Korean men.
METHODS
Data were used from the Korean Labor and Income Panel Study from 1999 to 2012. This study started with 2,737 subjects and included employed men in good health, aged 30-69 years. Deaths were tracked for 13 years from 2000 to 2012. Employment status classifications were: (1) regular employees, (2) precarious employees, (3) petty bourgeoisie, and (4) employers. Hazard ratios (HRs) were calculated using a Cox proportional hazards model, and were adjusted for age, education, income, and occupation, with regular employees as the reference category. To examine the effect of employment status and include employment history, the risk ratios of mortality were measured using the Poisson regression model, considering the duration of each employment and using 0 years as the reference category.
RESULTS
Over the course of the 13-year study, being a precarious employee (HR, 1.84) or petty bourgeoisie (HR, 1.87) at a particular point in time had a negative effect on mortality when compared with regular employees. Furthermore, working as precarious employees or petty bourgeoisie had no positive effect on mortality. A positive effect was observed, however, on the overall mortality risk for regular employees.
CONCLUSIONS
These results suggest that a healthy social policy is needed for precarious employees and petty bourgeoisie to avoid disadvantages in the workplace and the social safety net.
Summary
Korean summary
13년간 추적한 결과, 비정규직 노동자와 고용원이 없는 자영업자가 정규직 노동자에 비해 사망위험이 유의하게 높았다. 정규직 노동자에서는 일하는 것이 사망위험을 낮추는 긍정적인 효과를 관찰할 수 있었으나, 비정규직 노동자나 고용원이 없는 자영업자에서는 일하는 것의 긍정적인 효과를 관찰할 수 없었다. 이는 비정규직 노동자와 고용원이 없는 자영업자에 대한 건강한 사회 정책이 필요함을 시사한다.
Key Message
Over the course of the 13-year study, being a precarious employee or petty bourgeoisie had a negative effect on mortality when compared with regular employees. No positive effect of working was found for precarious employees or petty bourgeoisie, whereas cumulative work as a regular employee was observed to have a positive effect on mortality. These results suggest that a healthy social policy is needed for precarious employees and petty bourgeoisie to avoid disadvantages in the workplace and the social safety net.

Abstract
OBJECTIVES
This study aims to analyze the possibility and conditions of maintaining an effective reproductive number below 1 using a mathematical model.
METHODS
The total population was divided into five age groups (0-17, 18-29, 30-59, 60-74, and ≥75 years). Maximum likelihood estimation (MLE) was used to estimate the transmission rate of each age group. Mathematical model simulation was conducted until December 31, 2021, by establishing various strategies for vaccination and social distancing without considering variants.
RESULTS
MLE results revealed that the group aged 0-17 years had a lower risk of transmission than other age groups, and the older age group had relatively high risks of infection. If 70% of the population will be vaccinated by the end of 2021, then simulations showed that even if social distancing was eased, the effective reproductive number would remain below 1 near August if it was not at the level of the third re-spreading period. However, if social distancing was eased and it reached the level of the re-spreading period, the effective reproductive number could be below 1 at the end of 2021.
CONCLUSIONS
Considering both stable and worsened situations, simulation results emphasized that sufficient vaccine supply and control of the epidemic by maintaining social distancing to prevent an outbreak at the level of the re-spreading period are necessary to minimize mortality and maintain the effective reproductive number below 1.

본 연구에서는 질병관리청에서 제공하는 개별 확진자 데이터에 확률통계적 방법을 적용하여 연령군 간의 감염전파 행렬을 추정하였으며 연령군을 고려한 수리모델에 적용되었다. 본 연구에서 우리는 2020년 10월부터 2021년 5월까지 한국에서의 코로나19 유행상황을 정책 구간에 따라 분석하였으며 이를 토대로 거리두기 완화 수준에 따라 거리두기 완화 상태에서도 지속적으로 유효감염재생산지수가 1보다 작아지는 시점이 달라질 수 있음을 보인다.
Key Message
In this research, we estimated age-group-specified transmission rate matrix by applying maximum likelihood estimation into individual based data which was provided by Korea Disease Control and Prevention Agency. Our model simulation showed the moment, when the effective reproductive number is consistently below 1 even the distancing is eased, is ranged from August to the end of 2021 depending on the intensity of the social distancing during eased phase.

Abstract
OBJECTIVES
During the coronavirus disease 2019 (COVID-19) pandemic, crude incidence and mortality rates have been widely reported; however, age-standardized rates are more suitable for comparisons. In this study, we estimated and compared the age-standardized incidence, mortality, and case fatality rates (CFRs) among countries and investigated the relationship between these rates and factors associated with healthcare resources: gross domestic product per capita, number of hospital beds per population, and number of doctors per population.
METHODS
The incidence, mortality, and CFRs of 79 countries were age-standardized using the World Health Organization standard population. The rates for persons 60 years or older were also calculated. The relationships among the rates were analysed using trend lines and coefficients of determination (R<sup>2</sup>). Pearson correlation coefficients between the rates and the healthcare resource-related factors were calculated.
RESULTS
The countries with the highest age-standardized incidence, mortality, and CFRs were Czechia (14,253 cases/100,000), Mexico (182 deaths/100,000), and Mexico (6.7%), respectively. The R<sup>2</sup> between the incidence and mortality rates was 0.852 for all ages and 0.945 for those 60 years or older. The healthcare resources-related factors were associated positively with incidence rates and negatively with CFRs, with weaker correlations among the elderly.
CONCLUSIONS
Compared to age-standardized rates, crude rates showed greater variation among countries. Medical resources may be important in preventing COVID-19-related deaths; however, considering the small variation in fatality among the elderly, preventive measures such as vaccination are more important, especially for the elderly population, to minimize the mortality rates.

Key Message
The incidence, mortality, and case fatality rates of 79 countries were age-standardized using the WHO standard population. The correlations between the rates and the healthcare resource-related factors were investigated. As of April 6, 2021, the countries with the highest age-standardized incidence, mortality, and case fatality rates were Czechia (14,253 cases/100,000), Mexico (182 deaths/100,000), and Mexico (6.7%), respectively; the mortality and case fatality rates were higher among the elderly. GDP per capita, number of hospital beds per population, and number of doctors per population were associated positively with incidence rate, and negatively with case fatality rates: the correlations were weaker among the elderly. To minimize the burden caused by COVID-19, preventing the elderly from infection is important as well as supply of medical resources.

Abstract
OBJECTIVES
We examined the associations of individual and regional-level perceived stress and depression with health-related quality of life (HRQOL) in Korean adults.
METHODS
We used data from the 2017 Korea Community Health Survey, which included 216,713 adults living within 254 municipal districts. As individual-level independent variables, perceived stress (higher vs. lower) and depression (Patient Health Questionnaire-9 ≥10) were defined. Regional-level age-adjusted rates of perceived stress (%) and depression (%) were created for 254 municipal districts and categorized into quartiles to generate regional levels of stress and depression. HRQOL was defined as the individual-level EuroQol 5-dimensional index×100. A multilevel analysis was performed to identify the relationship between individual or regional-level independent variables and individual HRQOL.
RESULTS
In the null model, the proportions of individual variation in the HRQOL explained by region were 1.7% and 2.7% for men and women, respectively. When adjusted with all individual-level variables, regional stress and depression, as well as individual-level perceived stress and depression, were significantly related to HRQOL for both genders. In the full model including all variables, the decrease in HRQOL from the first to the fourth quartile group of regional stress was greater in women (-1.09; 95% confidence interval [CI], -1.87 to -0.31) than in men (-0.65; 95% CI, -1.04 to -0.26).
CONCLUSIONS
Our results suggest that regional-level perceived stress and depression, as well as individual-level perceived stress and depression, are inversely associated with individual HRQOL.

Key Message
This study examined the associations of regional-level perceived stress and depression with individual HRQOL measured in terms of the EQ-5D using a multilevel model. Individual-level perceived stress and depression were significantly related to individual HRQOL. Regional stress and depression were also significant factors and both had greater negative impacts on HRQOL among women than among men.

Abstract
OBJECTIVES
Data on associations between body temperature (BT) and leukocyte telomere length (LTL), which has been widely used as a biomarker of cellular senescence in recent epidemiological studies, are limited. Therefore, this study aimed to explore the associations between a normal BT range (35.0-37.5°C) and LTL via 6-year longitudinal observations of 2,004 male and female adults aged 50 or older.
METHODS
BT was obtained by measuring the tympanic temperature, and relative LTL was determined by real-time polymerase chain reaction. Robust regression analysis was used to evaluate the association between the baseline and follow-up LTL values and their differences.
RESULTS
A significant inverse association was found between BT and LTL at baseline. The regression coefficient estimate was -0.03 (95% confidence interval, -0.07 to -0.001; p<0.05). This association was stronger in participants with a body mass index >25 kg/m<sup>2</sup> and males (p<0.01). However, there were no associations between BT and LTL at follow-up or BT and 6-year longitudinal differences in LTL.
CONCLUSIONS
These findings suggest that having a high BT between 35°C and 37.5°C (95°F and 99°F) may be detrimental for obese individuals in terms of biological aging.

Key Message
In an epidemiological study including Korean adults, a relatively higher normal body temperature between 35°C to 37.5°C was found to be associated with shorter leukocyte telomere length, a cellular senescence biomarker. In particular, this association was observed to be stronger among obese participants, suggesting that attaining normal body weight may be beneficial for anti-aging.

Abstract
The general population is exposed to numerous environmental pollutants, and it remains unclear which pollutants affect the brain, accelerating brain aging and increasing the risk of dementia. The Environmental-Pollution-Induced Neurological Effects study is a multi-city prospective cohort study aiming to comprehensively investigate the effect of different environmental pollutants on brain structures, neuropsychological function, and the development of dementia in adults. The baseline data of 3,775 healthy elderly people were collected from August 2014 to March 2018. The eligibility criteria were age ≥50 years and no self-reported history of dementia, movement disorders, or stroke. The assessment included demographics and anthropometrics, laboratory test results, and individual levels of exposure to air pollution. A neuroimaging sub-cohort was also recruited with 1,022 participants during the same period, and brain magnetic resonance imaging and neuropsychological tests were conducted. The first follow-up environmental pollutant measurements will start in 2022 and the follow-up for the sub-cohort will be conducted every 3-4 years. We have found that subtle structural changes in the brain may be induced by exposure to airborne pollutants such as particulate matter 10 μm or less in diameter (PM<sub>10</sub>), particulate matter 2.5 μm or less in diameter (PM<sub>2.5</sub>) and Mn<sub>10</sub>, manganese in PM<sub>10</sub>; Mn<sub>2.5</sub>, manganese in PM<sub>2.5</sub>. PM<sub>10</sub>, PM<sub>2.5</sub>, and nitrogen dioxide in healthy adults. This study provides a basis for research involving large-scale, long-term neuroimaging assessments in community-based populations.

Key Message
The EPINEF cohort was started in 2014 to assess the risk of neurological diseases caused by environmental harmful factors and to provide evidence for neuropsychological dysfunction or brain aging induced by these factors. This cohort is the first long-term follow-up study in Korea to extensively investigate brain imaging markers and environmental harmful factors related to cognitive function, and several related research results have been published. In addition, the follow-up survey will be continued in the future, and we expect that the results of the study will contribute to improving health policies for the management of neurological diseases.

Abstract
OBJECTIVES
We reconstructed a coronavirus disease 2019 (COVID-19) outbreak to examine how a large cluster at a church setting spread before being detected and estimate the potential effectiveness of complying with mask-wearing guidelines recommended by the government.
METHODS
A mathematical model with a social network analysis (SNA) approach was used to simulate a COVID-19 outbreak. A discrete-time stochastic simulation model was used to simulate the spread of COVID-19 within the Sarang Jeil church. A counterfactual experiment using a calibrated baseline model was conducted to examine the potential benefits of complying with a mask-wearing policy.
RESULTS
Simulations estimated a mask-wearing ratio of 67% at the time of the outbreak, which yielded 953.8 (95% confidence interval [CI], 937.3 to 970.4) cases and was most consistent with the confirmed data. The counterfactual experiment with 95% mask-wearing estimated an average of 45.6 (95% CI, 43.4 to 47.9) cases with a standard deviation of 20.1. The result indicated that if the church followed government mask-wearing guidelines properly, the outbreak might have been one-twentieth the size.
CONCLUSIONS
SNA is an effective tool for monitoring and controlling outbreaks of COVID-19 and other infectious diseases. Although our results are based on simulations and are thus limited, the precautionary implications of social distancing and mask-wearing are still relevant. Since person-to-person contacts and interactions are unavoidable in social and economic life, it may be beneficial to develop precise measures and guidelines for particular organizations or places that are susceptible to cluster outbreaks.

본 연구는 구조화된 확률적 네트워크 시뮬레이션모형을 이용하여 국내에서 발생했던 사랑제일교회 발 코로나19 집단 감염 사례의 일별 확진자 데이터를 설명하고자, 마스크 착용 비율 추정과 반사실적 실험을 통해 방역지침을 준수한 경우 발생할 수 있었을 확진자의 규모를 추정하였다. 시뮬레이션 결과 추정된 당시 사랑제일교회의 마스크 착용 비율은 약 67% 수준이며, 만약 참석자의 95%가 마스크를 착용한 경우 확진자 규모는 실제의 20분의 1 수준에 그쳤을 것으로 예상된다. 마스크 착용은 예방접종과 함께 코로나 감염증을 극복하기 위한 가장 효과적인 예방활동이며 가장 마지막까지 강조되어야 할 것이다.
Key Message
To better understand the transmission of COVID-19 in a church setting, a stochastic social network analysis with a focus on mask-wearing practice was constructed. The results showed that if mask-wearing were to increase from 67% (at the time of the outbreak) to 95%, the outbreak could have been one-twentieth the size. Among the many measures of non-pharmaceutical intervention which may be withdrawn, mask-wearing is still one of the most effective precautionary measure and should continue to be emphasized.

Abstract
OBJECTIVES
This study aimed to validate a simple risk assessment tool for estimating the advanced colorectal neoplasia (ACN) risk at colonoscopy screenings and potential factors relevant for implementing this tool in the Korean population.
METHODS
Our study analyzed data from the Cancer Screenee Cohort Study conducted by the National Cancer Center in Korea. The risk level was assessed using the Asia Pacific Colorectal Screening (APCS) score developed by the Asia-Pacific Working Group on Colorectal Cancer. Logistic regression models were used to examine the associations between colorectal-related outcomes and the risk level by APCS score. The discriminatory performance of the APCS score for various colorectal-related outcomes was assessed using C-statistics.
RESULTS
In 12,520 individuals, 317 ACN cases and 4,528 adenoma cases were found. The APCS tool successfully classified the study population into different risk groups, and significant differences in the ACN rate and other outcomes were observed. The APCS score demonstrated acceptable discrimination capability with area under the curve values ranging from 0.62 to 0.65 for various outcomes. The results of the multivariate logistic regression model revealed that the high-risk group had a 3.1-fold higher risk of ACN (95% confidence interval, 2.08 to 4.67) than the average-risk group. Body mass index (BMI) was identified as a significant predictor of ACN in both multivariate and subgroup analyses.
CONCLUSIONS
Our study highlighted significant differences in colorectal-related screening outcomes by colorectal risk level measured using the APCS score, and BMI could be used to improve the discriminatory capability of the APCS score.
Summary
Korean summary
검진의 위해성을 줄이면서 동시에 이득을 최대화할 수 있는 최적의 검진 프로그램은 암 발생 위험도를 고려하는 것이다. 이 연구는 Asia-Pacific Working Group on Colorectal Cancer에서 제안한 “Asia Pacific Colorectal Screening Score (APCS)”가 한국인에서 대장암 발생 위험도를 선별적으로 잘 구분해 낼 수 있음을 보여주었다. 나아가 대장암의 위험도 점수를 산출하는데 체질량지수가 중요한 예측 변수라는 것을 확인하였고, 한국인에서 대장암 발생 위험도의 변별력을 향상시키기 위해 기존의 APCS에 체질량지수를 추가할 것을 제안하였다.
Key Message
This study highlighted that the Asia Pacific Colorectal Screening Score by the Asia-Pacific Working Group on Colorectal Cancer could successfully classify Korean screenees into different risk groups with acceptable discriminatory capability. Furthermore, our study results also suggest that BMI is a significant predictor of colorectal-related health outcomes, which could be potentially added to the original APCS score for improving its discriminatory power.
