Abstract
OBJECTIVES
Lifestyles, including exercise behaviors, change continually over time. This study examined whether the clinical biomarkers (CBs) related to cardiometabolic diseases (CMDs) and their relationships differed with changes in exercise behavior.
METHODS The Ansan-Ansung cohort study (third to fifth phases; n=2,668) was used in the current study. Regular exercise behavior was investigated using a yes/no questionnaire. Changes in exercise behavior were classified into 4 groups: Y-N, N-Y, Y-Y, and N-N, with “Y” indicating that a participant regularly engaged in exercise at a given time point and “N” indicating that he or she did not. Fourteen CBs related to CMDs were used, and the associations between changes in exercise behavior and relative changes in CBs were examined. CB networks were constructed and topological comparisons were conducted.
RESULTS Y-N was associated with increases in fasting blood sugar and insulin levels in men, and increased total cholesterol and low-density lipoprotein cholesterol levels in women. Meanwhile, N-Y was inversely associated with body fat percentage, visceral fat percentage, fasting insulin, and triglyceride level. Waist circumference played a central role in most networks. In men, more edges were found in the N-Y and Y-Y groups than in the N-N and Y-N groups, whereas women in the N-Y and Y-Y groups had more edges than those in the N-N and Y-N groups.
CONCLUSIONS Consistent exercise or starting to engage in regular exercise had favorable effects on CBs related to CMDs, although their network patterns differed between the sexes.

Abstract
OBJECTIVES
The purpose of this study was to explore the association between adherence to 2 cancer prevention recommendations and cancer risk.
METHODS In total, 104,386 individuals aged 40-69 years old who were recruited between 2004 and 2013 in the Health Examinees-Gem study were included. Adherence scores were constructed based on 8 items from the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) cancer prevention recommendations, including body weight, physical activity, diet, alcohol consumption and breastfeeding, and on 6 items from the Korean cancer prevention guidelines (smoking status, eating vegetables and fruits, salty foods, alcohol intake, physical activity, and body weight). A Cox proportional hazards model was used to estimate the associations between adherence scores and the risk of total and 5 major cancers.
RESULTS The multivariable hazard ratio (HR) for total cancer with the high adherence score versus the lowest score (4.25-7.00 vs. 0.00-3.25) for the WCRF/AICR guidelines was 0.91 (95% confidence interval [CI], 0.82 to 1.00) in men. A reduced breast cancer risk was observed among women with the highest score. Men within the highest category of the Korean cancer prevention guideline score (3.25-6.00) had an HR of 0.80 (95% CI, 0.73 to 0.88) for developing total cancer compared to men within the lowest score (0.00-2.50). The higher adherence group among men showed lower risks of developing stomach, colorectal, and lung cancers.
CONCLUSIONS Adhering to guidelines for cancer prevention can help to reduce the risk of developing cancer in Korean men. The association might differ by cancer type and gender.

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
Although the association of genetic polymorphisms in glutathione S-transferase(GST) and N-acetyltransferase(NAT) with bladder cancer has been reported, limited numbers of studies have been indicated the association of CYP2E1 with bladder cancer, particularly in Asian population.
A hospital based case-control study was conducted in South Korean, consisting of 232 histologically confirmed prevalent bladder cancer cases and 165 controls to evaluate the association between genetic polymorphisms of CYP2E1(RsaI) and development of bladder cancer. The frequency of CYP2E1(RsaI) c1/c1 genotype in bladder cancer cases was higher than in controls; 114 of 201(56.7%) vs. 62 of 146(42.5%). Men with CYP2E1(RsaI) c1/c1 genotype had increased risk of development of bladder cancer compared to men with at least one c2 allele(OR=1.7, 95% CI=1.1-2.7). The bladder cancer risk increased as the number of c1 allele increased(p for trend=0.005). The risk increased as the amount of smoking increased(p for trend=0.009). When data were analyzed for the interaction between smoking and CYP2E1 genetic polymorphisms, smokers with c1/c1 genotype have 2.5 greater risk in development of bladder cancer(95% CI=1.0-6.2) compared to nonsmokers with c2 allele(p for interaction=0.008). Our findings suggest that the interaction between genetic polymorphisms of CYP 2E1 (RsaI, c1/c1) and smoking may play an important role for development of bladder cancer among Koreans.

Abstract
PURPOSE
A hospital-based case-control study was conducted to evaluate the role of glutathione-S-transferase(GST)M1 and GSTT1 genetic polymorphism for developing benign breast disorders(fibrocystic diseases and fibroadenoma) in Korea.
MATERIALS AND METHODS: Histologically confirmed incident cases of benign breast disorder(n=56) were selected from inpatients at the Department of General Surgery, Seoul National University Hospital since 1994. Women with free of self-reporting past history of any malignancies were regarded as controls who were selected from the inpatients at the same department at three hospitals during 1994 to 1998(n=180). Information on life-styles including reproductive factors were obtained by direct interview using questionnaire. Age and menopausal status were matched and 51 cases and 102 controls were finally selected. Odds ratio and 95% confidence interval were estimated by multiple logistic regression after adjusting for age, education, body mass index, smoking history, drinking history, menstrual regularity, age at menarch, age at first pregnancy, frequency of fullterm pregnancy, breast feeding history, duration of breast feeding, and family history of breast cancer.RESULTS GSTM1-null type showed no significance related to the risk of benign breast disorder(adjusted OR=0.8, 95% CI=0.38-1.83) and GSTT1-null type was also not significant(adjusted OR=1.4, 95% CI=0.63-3.29). Increasing tendency of disease risk by the number of GSTs null type was not observed (ptrend>0.1) after adjusting for all other variables.DISCUSSIONS Further investigation with larger sample size should be needed to provide more concrete information on the role of GST genetic polymorphism in benign breast cancer and a lots of studies relation in normal level of GST genetic polymorphism in general population should be performed.

Abstract
PURPOSE
A hospital-based case-control study was conducted to figure out the risk factors for benign breast disorders in Korea.
MATERIALS AND METHODS: Histologically confirmed incident cases of benign breast disorders(n=54) were selected from inpatients with life-style information at the Department of General Surgery, Seoul National University Hospital during 1994 to 1997. Women with free of self-reporting past history of any malignancies were regarded as controls who were selected from the inpatients at the same department of the same hospital(n=180). Information on life-styles including reproductive factors were obtained by direct interview using questionnaire. Adjusted odds ratios and 95% confidence intervals were estimated by multivariate logistic regression model with matching variables.RESULTS Overall, higher educational level, family history of breast cancer, alcohol drinking, and older age at first fullterm pregnancy related to the risk of benign breast disorders. For premenopausal women, older age, higher educational level, and family history of breast cancer increased the risk of benign breast disorders. For postmenopausal women, alcohol drinking, older age at first fullterm pregnancy, and more frequent experiences of fullterm pregnancy increased the risk. Elder age in postmenopausal women and the experience of breast feeding had, however, protective effect against benign breast disorders.CONCLUSIONS Although the risk factors for benign breast disease may differ from those for breast cancer, these findings are consistent with the hypothesis of excessive circulating estrogen. The present data indicate some risk factors of benign breast disorders are confirmed as risk factors for breast cancer though a substantial agreement between the risk factors for (pathologically confirmed) benign and malignant breast disease.

Abstract
To develop the occupational cancer surveillance system in Korea, data linkage analysis was performed on the subjects of Health-monitoring-pocketbook (the list of subjects who were exposed to selected occupational carcinogens) and the retired workers of a cokes manufacturing factory using the Korean medical insurance data, Korean death certificate data and Korean cancer registry data.
Study subjects comprised the 822 retired subjects and the 3101 present-post subjects of Health-monitoring-pocketbook and the 182 retired workers of a cokes manufacturing factory. The incidence of cancer of these study subjects was ascertained by linkage of Korean medical insurance data of year 1995-6, Korean death certificate data of year 1992-8 and Korean cancer registry data of year 1993-5.
In the study subjects, Eighty seven percent were males and mean age was 39.3+/-8.9 year-old, Average work duration was 8.0+/-5.5 years. Chrome, asbestos and cokes were the most frequent exposed agents. In the study subjects, total 13 cancer cases were ascertained by data linkage analysis. In the ascertained cancer cases, 8 cases were male and 5 cases were female, and 7 cases were aged 40-49 yr, 5 cases were aged 50-59 yr and 1 cases were aged 30-39 yr. The commonest exposure agent in the ascertained cancer cases was asbestos and cokes. By the site of cancer, 3 stomach cancer cases, 2 hematopoietic cancer cases and 2 biliary tract cancer cases were ascertained.
The occupational cancer surveillance system using data linkage analysis on the workers exposed to hazardous agents was the most feasible and efficient method in Korea. And to do this, establishment of occupational history information in several disease registry database is needed with the effort of estimating the proper size of workers exposed hazardous agents.

Abstract
Occupational asthma is defined as a disease that is characterized by airway narrowing and bronchial hyperresponsiveness caused by specific working environment.
It is estimated that occupational asthma cases in Korea have been underreported. This study, using Korean Medical Insurance Data(KMID), examined the distribution of asthma patients' occupations and the frequency of high risk occupations for occupational asthma in Seoul, Korea to evaluate the usefulness of the KMID data as a database for active occupational asthma surveillance system.
Six hundreds and forty two(30.7%) of 2093 patients who were finally chosen as a study population by using 1995-year KMID, were contacted by telephone. 296 persons(47.4%) of 642 patients replied that they were diagnosed as asthma. The occupations of 296 asthma patients were classified by Korean standardized industrial classfication (KSIC). The most common occupations included Wholesale and Retail trade(19.5%), Real estate, Renting and Business activities(14.9%), Construction(14.9%), Manufacturing(12.3%). Forty(13.5%) of 296 patients who could be classified by KSIC were working at high risk jobs for occupational asthma.
KMID could be used as a useful data for occupational asthma surveillance system if the limitations of KMID, which is the accuracy of diagnosis, data accessibility, difficulty of following up study subjects, would be solved. The prevalence of occupational asthma could be estimated if the follow-up study diagnosing occupational asthma for asthma patients working in high risk jobs would be held.
