Abstract
This study presents the nutrition survey methods and the updated food composition database for the Korean Genome and Epidemiology Study (KoGES). The KoGES, which is the largest and longest cohort study in Korea, aims to identify genetic and environmental factors associated with chronic diseases. This study has collected dietary data using a validated semi-quantitative food frequency questionnaire and/or the 24-hour recall method. However, these dietary survey methods use different food composition databases, and their nutritional values are out of date. Therefore, it became necessary to update the food composition database by revising nutrient analysis values to reflect improvements in the performance of food ingredient analysis equipment, revising international values to analysis values of Korean agricultural products, adjusting nutrient units, and adding newly reported nutrients related to chronic diseases. For this purpose, we integrated the different food composition databases used in each nutrition survey, updated 23 nutrients, and expanded 48 new nutrients for 3,648 food items using the latest reliable food composition databases published by national and international institutions. This revised food composition database may help to clarify the relationship between various nutrients and chronic diseases. It could serve as a valuable resource for nutritional, epidemiological, and genomic research and provide a basis for determining public health policies.

Abstract
OBJECTIVES
To identify the distinct trajectories of sedentary behavior (SB) and explore whether reduced cardiovascular disease (CVD) risk was associated with a distinct trajectory of physical activity (PA).
METHODS
We analyzed data from 6,425 people who participated in the Korean Health Panel Survey over a period of 10 years. The participants’ self-reported SB and PA were assessed annually, and trajectory groups were identified using a group-based trajectory model for longitudinal data analysis. Logistic regression analysis was performed to assess the association between CVD risk (10-year cumulative incidence) and the trajectories of SB and PA. The adjusted variables included socio-demographic factors, the predisposing diseases of CVD, and baseline health behaviors.
RESULTS
Trajectory analysis identified 4 SB trajectory groups: SB group 1 (low and slightly increasing trend, 53.1%), SB group 2 (high and rapidly decreasing trend, 14.7%), SB group 3 (high and slightly decreasing trend, 9.9%), and SB group 4 (low and rapidly increasing trend, 22.2%). The 3 PA trajectory groups were PA group 1 (moderate and slightly decreasing trend, 32.1%), PA group 2 (low and slightly decreasing trend, 57.3%), and PA group 3 (maintained inactivity, 10.7%). By the 10-year follow-up, 577 cases of incident CVD had occurred. We also noted a 50% reduction in the risk of CVD when SB group 4 was accompanied by PA group 1 (odds ratio, 0.50; 95% confidence interval, 0.28 to 0.90).
CONCLUSIONS
Despite increased time spent in SB, maintaining PA about 2 days to 3 days per week reduced the occurrence of CVD.

Abstract
OBJECTIVES
Population aging is rapidly accelerating worldwide. Oral diseases related to aging are also on the rise. This study examined trends in the incidence of edentulism among the older Korean population using data from the Korean National Health Insurance Service (KNHIS).
METHODS
Data on older adults, aged ≥75 years of age, were obtained from the KNHIS for the period 2013-2018. Edentulism was defined as a treatment history of complete dentures in the KNHIS database. The exclusion criteria consisted of both disease codes and treatment codes related to conservative dental treatment, including periodontal and extraction treatment afterward. Crude incidence rates (CIRs) and age-standardized incidence rates (AIRs) with 95% confidence intervals were calculated and reported per 100,000 person-years by the direct method. Trends were tested by Cochrane Armitage models.
RESULTS
Statistically significant increasing trends in both CIRs and AIRs were found among the older Korean population registered in the KNHIS (CIRs, 707.92 to 895.92; AIRs, 705.11 to 889.68; p<0.01). The incidence tended to increase in both genders (p<0.01). Both CIRs and AIRs in specific regions also showed slight but significant annual increases except for Jeju Island (p<0.01 or <0.05). The incidence showed increasing trends (p<0.01) in all income quintiles apart from the highest quintile. The edentulism incidence was highest in the lowest income group (the first quintile).
CONCLUSIONS
Our data showed that the incidence of edentulism among the elderly showed an increasing trend from 2013 to 2018. This result provides a basis for future epidemiological studies on the incidence of edentulism in the older Korean population.

Abstract
OBJECTIVES
This study aimed to investigate the association between levels of physical activity (PA) and low handgrip strength in Korean adults.
METHODS
Our cross-sectional study design included 24,109 Korean adults older than 19 years of age who participated in the Korea National Health and Nutrition Examination Survey 2014–2019. Low handgrip strength is described as hand strength less than the cut-off value of the 20th percentile of handgrip strength from a healthy population in each gender and age group. PA was categorized into three levels (inactive, active, and highly active) according to the World Health Organization’s global recommendations on PA for health. Multivariable logistic regression analysis was used to examine the association between levels of PA and low handgrip strength.
RESULTS
Odds ratios (ORs) for low handgrip strength were significantly higher in middle-aged women who were active (adjusted odds ratio [aOR], 1.40; 95% confidence interval [CI], 1.15 to 1.69) and inactive (aOR, 1.47; 95% CI, 1.23 to 1.76) than in those highly active in walking exercise. Most of older people had significantly higher ORs for low handgrip strength in active compared to highly active in the context of aerobic, muscle strengthening, and walking exercise.
CONCLUSIONS
Walking exercise was associated with a lower risk of sarcopenia in middle-aged women and older individuals. However, further studies are necessary to confirm the causal relationship between levels of PA and low handgrip strength.
Summary
Korean summary
본 연구는 국민건강영양조사 2014-2019년도 자료를 활용하여 한국인 만 19세 이상 건강한 성인을 대상으로 낮은 악력의 기준값을 성별 및 연령그룹별로 도출하고 유산소 운동, 근력 운동, 걷기 운동 수준과 낮은 악력의 연관성을 분석하였다. 분석 결과, 중년 여성과 노년층에서 걷기 운동이 근감소증 발생의 예방과 연관성이 있음을 알 수 있었다.
Key Message
The association between levels of physical activity and low handgrip strength was different by sex and age groups. For women, walking exercise was associated with low handgrip strength, but not for men. By age groups, muscle strengthening exercise could help prevent sarcopenia in the young population, aerobic exercise has the potential to prevent sarcopenia in middle-aged individuals, and walking exercise could reduce sarcopenia risk in older individuals.

Abstract
OBJECTIVES
The purpose of this study was (1) to examine whether the addition of resting heart rate (RHR) to the existing undiagnosed diabetes mellitus (UnDM) prediction model would improve predictability, and (2) to develop and validate UnDM prediction models by using only easily assessable variables such as gender, RHR, age, and waist circumference (WC).
METHODS
Korea National Health and Nutrition Examination Survey (KNHANES) 2010, 2012, 2014, 2016 data were used to develop the model (model building set, n=19,675), while the data from 2011, 2013, 2015, 2017 were used to validate the model (validation set, n=19,917). UnDM was defined as a fasting glucose level ≥126 mg/dL or glycated hemoglobin ≥6.5%; however, doctors have not diagnosed it. Statistical package for the social sciences logistic regression analysis was used to determine the predictors of UnDM.
RESULTS
RHR, age, and WC were associated with UnDM. When RHR was added to the existing model, sensitivity was reduced (86 vs. 73%), specificity was increased (49 vs. 65%), and a higher Youden index (35 vs. 38) was expressed. When only gender, RHR, age, and WC were used in the model, a sensitivity, specificity, and Youden index of 70%, 67%, and 37, respectively, were observed.
CONCLUSIONS
Adding RHR to the existing UnDM prediction model improved specificity and the Youden index. Furthermore, when the prediction model only used gender, RHR, age, and WC, the outcomes were not inferior to those of the existing prediction model.
Summary
Korean summary
당뇨병 미인지 또는 미진단은 적절한 치료 시작 시기를 늦추고 당뇨병 합병증 발생의 위험을 높이기 때문에, 각국은 당뇨병 예측 모형을 개발하여 당뇨병을 조기에 예측하고, 치료 시기를 앞당기기 위해 노력하고 있다. 본 연구는 기존의 한국인 당뇨병 예측 모형에 안정시심박수를 추가 변수로 포함시켜, 예측 모형의 성능이 일부개선되는 것을 확인하였고, 더 나아가 나이, 허리 둘레, 그리고 안정시심박수를 포함하여 예측 모형을 개발하고, 그 성능을 확인하였다. 본 연구에서는 간단하게 측정이 가능한 허리 둘레와 안정시심박수 그리고 나이만 포함한 예측 모형이 기존의 예측 모형과 비교해 성능이 열등하지 않은 것을 확인하였다.
Key Message
Higher RHR is associated with increased risk of diabetes. When RHR is added to the Korean undiagnosed diabetes risk score model (Age, Family history of diabetes, Hypertension, Waist circumference, Smoking, Alcohol consumption), the model somewhat increased its predictability of undiagnosed diabetes. Furthermore, the prediction model developed only using age, waist circumference and RHR, which anyone can easily measure or access, had similar predictability to the previous undiagnosed diabetes risk prediction model. The results of this study may help develop future strategies or applications for predicting early undiagnosed diabetes.

Abstract
OBJECTIVES
Although previous studies have investigated the correlation between fruit and vegetable consumption and depression, the results remain inconclusive. The present study aimed to investigate the association between weekly fruit and vegetable consumption and depressive symptoms in elderly Koreans.
METHODS
A multiple covariate linear regression analysis was performed using the data of 1,226 elderly individuals ≥ 60 years of age who participated in the Korean Elderly Environmental Panel II study from 2012 to 2014. Depressive symptoms were evaluated using the Korean version of the Short form Geriatric Depression Scale (SGDS-K). Generalized linear mixed-effects models were constructed to analyze the repeated measurements of 305 people who participated in the survey every year.
RESULTS
After adjusting for confounders, SGDS-K scores were negatively associated with the frequency of weekly fruit consumption as follows (β [95% confidence interval; CI]: -0.17 [-0.28 to -0.05], -0.17 [-0.27 to -0.07], -0.42 [-0.54 to 0.29], and -0.33 [-0.44 to -0.21]) for less than 1 time/wk, 1-3 times/wk, 4-6 times/wk, and daily, respectively, compared to no consumption. The SGDS-K scores were also negatively associated with the frequency of vegetable consumption (β [95% CI]: -0.86 [-1.18 to -0.55], -0.18 [-0.35 to -0.01], -0.36 [-0.53 to -0.18], and -0.15 [-0.29 to 0.00]) in the above order, respectively.
CONCLUSIONS
Fruit consumption was inversely associated with depression levels in a dose-dependent manner. Although there was no dose-response relationship between vegetable consumption and the level of depression, it was negatively associated with SGDS-K scores.

Abstract
OBJECTIVES
Suicide and drinking problems in adolescents are increasing every year, and it is known that suicide is related to drinking. This study aims to identify the relationship between binge drinking experience (BDE) and suicide attempts in Korean adolescents.
METHODS
The Ninth Korean Youth Risk Behavior Web-based Survey (KYRBS), conducted in 2013, was used for analysis. Multiple logistic regression analysis was used to identify the relationship between BDE and suicide attempts, and the relationship between BDE and suicide attempts in middle and high school students was stratified by age.
RESULTS
BDE and suicide attempts were highly related. The odds ratio (OR) of attempted suicide in BDE was 1.63 times (95% confidence interval [CI], 1.28 to 2.09) higher then non-drinking in males. And the OR of attempted suicide in females was 1.21 times (95% CI, 1.07 to 1.37) higher then non-drinking in non-BDE, 1.79 times (95% CI, 1.47 to 2.19) higher in BDE. BDE was associated with suicide attempts in males aged 12 or 13 years (OR, 3.97; 95% CI, 1.57 to 10.03) and in females aged 15 years (OR, 2.66; 95% CI, 1.79 to 3.96).
CONCLUSIONS
BDE is an important factor related to suicide attempts in adolescents. In order to reduce suicide attempts, it is necessary to educate the youth about the regulation of BDE and drinking prevention.

Logistic regression analysis after PSM showed that gender, age, marital status, educational level, monthly household income, employment type, alcohol drinking, smoking, body mass index group, chronic disease, and subjective health status influenced the CSB, there were statistical differences.
CONCLUSIONS
To improve cancer screening (CS), it is necessary to educate individuals on the need for CS and to carry out a personalized CS program based on an individual’s demographic status and health behavior.

Abstract
OBJECTIVES
With an increasing number of studies highlighting regional social capital (SC) as a determinant of health, many studies are using multi-level analysis with merged and averaged scores of community residents’ survey responses calculated from community SC data. Sufficient examination is required to validate if the merged and averaged data can represent the community. Therefore, this study analyzes the validity of the selected indicators and their applicability in multi-level analysis.
METHODS
Within and between analysis (WABA) was performed after creating community variables using merged and averaged data of community residents’ responses from the 2013 Community Health Survey in Korea, using subjective self-rated health assessment as a dependent variable. Further analysis was performed following the model suggested by WABA result.
RESULTS
Both E-test results (1) and WABA results (2) revealed that single-level analysis needs to be performed using qualitative SC variable with cluster mean centering. Through single-level multivariate regression analysis, qualitative SC with cluster mean centering showed positive effect on self-rated health (0.054, p<0.001), although there was no substantial difference in comparison to analysis using SC variables without cluster mean centering or multi-level analysis.
CONCLUSIONS
As modification in qualitative SC was larger within the community than between communities, we validate that relational analysis of individual self-rated health can be performed within the group, using cluster mean centering. Other tests besides the WABA can be performed in the future to confirm the validity of using community variables and their applicability in multi-level analysis.

Abstract
<sec><title>OBJECTIVES</title><p>Several studies have found a significant association between the presence of earlobe crease (ELC) and cardiovascular disease (CVD). Brachial-ankle Pulse Wave Velocity (baPWV) is a non-invasive and useful measure of arterial stiffness predicting cardiovascular events and mortality. However, few studies have reported the relationship between ELC and baPWV as a new measure of arterial stiffness. The purpose of this study was to determine whether ELC is related to baPWV in non-diabetic, non-hypertensive, and apparently healthy Korean adults.</p></sec><sec><title>METHODS</title><p>A cross-sectional study was conducted on 573 non-hypertensive, non-diabetic Korean adults aged 20-80 yr. Subjects were stratified into three groups according to gender and menopausal status. baPWV was measured by an automatic waveform analyser. The association between ELC and baPWV was assessed by multiple linear regression analysis after adjusting for conventional cardiovascular disease risk factors including age, gender, blood pressure, lipid profile, and smoking status etc.</p></sec><sec><title>RESULTS</title><p>The overall frequency of ELC was 19.02% and the subjects with ELC showed significantly higher mean baPWV (p<0.0001). Multiple linear regression of subjects revealed that the presence of ELC was independently associated with baPWV (male, p<0.0001; premenopausal female p=0.0162; postmenopausal female p=0.0208).</p></sec><sec><title>CONCLUSION</title><p>ELC had a significant correlation with baPWV, independently controlling for other classical cardiovascular risk factors in adults aged 20 yr or older. ELC is an important surrogate marker of increased arterial stiffness as measured by baPWV in Korean adults.</p></sec>

Abstract
PURPOSE
The purpose of this study was to investigate the prevalence rate of HBsAg and the epidemiological characteristics of hepatitis B virus (HBV) infection from 1998 to 2005. National Health and Nutrition Examination Survey (NHANES) data of 1998, 2001 and 2005 were analyzed.
METHOD
Study population was consisted of 24,093, aged 10 year or over who performed NHANES self reported surveys and blood tests. Statistical analysis was performed by age, sex, and the year of survey. Also the prevalence of HBsAg was compared by self reported family history of liver disease.
RESULTS
The prevalence rate of HBsAg was reduced from 4.5% in 1998 to 3.7% in 2005. Also age-specific prevalence rate of HBsAg was significantly decreased in persons born after introduction of the hepatitis B virus vaccination. HBsAg seropositivity was slightly higher in male than in female. Among the people with the family history of liver diseases, the risk of HBsAg seropositive was much higher than those without. Study subjects with mother's liver disease history showed much higher HBsAg serepositive rate. Although after the implementation of hepatitis B virus vaccination program prevalence of HBsAg decreased, but persons with history of liver disease showed still higher rate Of HBsAg seropositive rate.
CONCLUSION
Although the introduction of the HBV vaccination program has resulted in a decline of HBV infection, the family history of liver diseases was still an important factor for transmission of HBV in Korea. In addition to the mother-to-child transmission prevention program from 2002, it might be advisable to introduce a screening program for persons with family history of liver diseases for further reduction of HBV infection.

Abstract
PURPOSE
Homocysteine is a known independent risk factor for cardiovascular diseases and its blood levels are influenced by several factors such as race, diet, and lifestyle, so on. Considering these factors, the normal value for total homocysteine has not been determined in Korea. The objective of this study is to establish the normal value for serum total homocysteine and elucidate the prevalence rate of hyperhomocysteinemia by gender and age. SUBJECTS AND METHODS: Among the participants of a community-based cohort study conducted in Yangpyeong province, 889 subjects were measured the biochemical analytes including homocysteine. Those who had the medical histories of angina, myocardial infarction and/orstroke, those who had low levels of folate and/or vitamin B12 and those who had high creatinine level were excluded. Finally, 506 subjects were selected as the reference population. A normal value was established with Clinical and Laboratory Standards Institute C28-A2 protocol.
RESULTS
Homocysteine concentrations of total 889 population and 506 reference population were 10.3+/-5.7 micromol/L (1.9 ~ 93.9 micromol/L) and 8.8+/-2.5 micromol/L (4.3 ~ 21.4 micromol/L), respectively. Homocysteine level was significantly higher in men compared to women (P<0.001) and was significantly increased with age. Normal values were 6.7~15.3micromol/L for men and 5.2~12.7 micromol/L for women. With the normal values, the prevalence rates of hyperhomocysteinemia were 13.3% for men and 8.5% for women in total 889 population. The prevalence rate was highest for individuals aged 60 years or older.
CONCLUSIONS
These data on homocysteine concentrations are similar to from different countries. The established normal value might be used to evaluate quantitatively the risk for hyperhomocysteinemia.

Abstract
The Korea National Health and Nutrition Examination Survey is a nationwide health survey in Korea. This survey is composed of three parts: the Health Interview Survey, the Health Examination Survey, and the Nutrition Survey. The aim of this study was to refine the nutrition survey system in the Korean National Health and Nutrition Examination Survey (KNHANES). Based on the literature review, we summarized international survey systems and the limitations of the current system in Korea and proposed an improved system. We suggested the following: 1) A government agency which will be exclusively responsible for KNHANES overall is needed. 2) The current short-term nutrition survey should be a year-round survey. 3) The objectives of this survey should be written with more clarity and detail. 4) Biochemical measures in relation to nutritional status should be added. 5) The budget to set up various databases in the nutrition survey should be increased. 6) Various other issues should be addressed, including the definition of raw data (i.e., whether nutrient intake data per day is raw data), ethical issues in survey techniques, and strategies to produce evidence for the public using this survey data. Not all suggestions could be adopted in the short-term, but should be integrated into long-term goals for survey system improvement.

Abstract
This study was conducted to assess the risk of breast cancer by menstrual, reproductive, and lactational factors in Korean women. A total of 210 women living in Seoul aged 30 to 60 with a first diagnosis of breast cancer from 2 teaching hospitals in Seoul, and 249 control subjects, randomly selected from the female pensioners of Korean Medical Insurance Company living in Seoul were interviewed. There was a increasing risk with the decrease of age at menarche, and the adjusted odds ratio(OR) of early menarche(age 14 years or less compared with over 17 years) was 1.61(95% Confidence Interval [CI]: 0.95-2.74). The longer the interval between menarche and regular menstruation, the less risk of breast cancer(OR=0.31, 95% CI: 0.16-0.60). The effect of these menarche factors were more prominent among premenopausal women. The adjusted OR for the second category(25-29 years old) of the age at first pregnancy and the age at the first full term pregnancy, compared to the reference category( 24 years old), were 0.52(95% CI: 0.30-0.92) and 0.58(95% CI: 0.32-1.06), respectively. The late age at the last full term pregnancy had significant protective effect (OR=0.29, 95% CI: 0.10-0.88), and the age itself was important rather than the interval between the first and last full term pregnancy. Factors related to breast feeding(BF) had protective effect consistently. Among parous women, in referent to no BF, women with 1 year of BF had adjusted OR of 0.34(95% CI: 0.17-0.68), while those with 1-3 years of BF had 0.35(95% CI: 0.18-0.67), 3-5 years had 0.29(95% CI: 0.12-0.74), and more than 5 years had 0.06(95% CI: 0.02-0.17). Age at menarche with regular cycle have stronger effect on especially pre-menopausal breast cancer among Korean women. Recent increase in breast cancer incidence in Korea would be explained by delayed age at first pregnancy or delivery, earlier age at menarche and last delivery, and decrease in brest feeding.
