This study aimed to analyze the occurrence of colon polyps and also risk factors of colon polyps. Among health examination examinees, 508 people were included who underwent colonoscopy and abdominal ultrasonography at the same time. Physical measurements also performed such as height, weight, blood pressure, waist measurement and BMI. General characteristics including age, sex, smoking, drinking and exercise as a risk factors were checked. At the same time, we analyzed various blood tests and fasting blood sugar through blood-gathering. In the results, regarding risk factors of colon polyps, AST, ALT, TC, fatty liver, obesity and smoking were shown significantly high. As a dependent variable with colon polyps, the highest relation was fatty liver(3.4 times), and then T-C(2.3 times). Smoking factor showed 2.3 times higher relation than non-smokers.

Purpose: The purpose of this study is to classify space types according to the operating system of health examination centers and compare and analyze their sizes. Methods: Seven examination centers under the K Medical Research Institute with the same operating system and similar examination types and functional spaces are the subject of the investigation. Research is conducted through field investigation, user surveys, and drawing analysis. Results: The operating method of the health examination center can be largely divided into the function dispersed type and the function central type. The function dispersed type was planned as a vertical type, and the function central type was planned as a horizontal type. In the case of the function dispersed type, since the examinees move vertically to use the endoscope center and special examination center, the efficiency of the vertical movement must be considered when planning the function dispersed type of facility. The function dispersed type plans to increase work and manpower efficiency by arranging the areas used at the start and end of the examination. Because the function central type horizontally arranges related functions by area, it should be planned in a structure that makes it easy for examinees to find their way. Implications: Through this study, it is judged that it is possible to suggest architectural planning considerations that vary depending on the operation system of the examination center.

Purpose : The purpose of this study was to establish a model of the predictive factors for success or failure of examinees undertaking the Korean physical therapist licensing examination (KPTLE). Additionally, we assessed the pass/fail cut-off point. Methods : We analyzed the results of 10,881 examinees who undertook the KPTLE, using data provided by the Korea Health Personnel Licensing Examination Institute. The target variable was the test result (pass or fail), and the input variables were: sex, age, test subject, and total score. Frequency analysis, chi-square test, descriptive statistics, independent t-test, correlation analysis, binary logistic regression, and receiver operating characteristic (ROC) curve analyses were performed on the data. Results : Sex and age were not significant predictors of attaining a pass (p>.05). The test subjects with the highest probability of passing were, in order, medical regulation (MR) (Odds ratio (OR)=2.91, p<.001), foundations of physical therapy (FPT) (OR=2.86, p<.001), diagnosis and evaluation for physical therapy (DEPT) (OR=2.74, p<.001), physical therapy intervention (PTI) (OR=2.66, p<.001), and practical examination (PE) (OR=1.24, p<.001). The cut-off points for each subject were: FPT, 32.50; DEPT, 29.50; PTI, 44.50; MR, 14.50; and PE, 50.50. The total score (TS) was 164.50. The sensitivity, specificity, and the classification accuracy of the prediction model was 99 %, 98 %, and 99 %, respectively, indicating high accuracy. Area under the curve (AUC) values for each subject were: FPT, .958; DEPT, .968; PTI, .984; MR, .885; PE, .962; and TS, .998, indicating a high degree of fit. Conclusion : In our study, the predictive factors for passing KPTLE were identified, and the optimal cut-off point was calculated for each subject. Logistic regression was adequate to explain the predictive model. These results will provide universities and examinees with useful information for predicting their success or failure in the KPTLE.

Objectives: Most cohort studies used food frequency questionnaires (FFQ) to evaluate coffee consumption as it assesses habitual dietary patterns, whereas some studies have used the 24-hour recalls (24HR) as it elicits in-depth description of foods and the amount eaten. The aim of this study was to compare FFQs and 24HR to assess the consumption of various types of coffee. Methods: We included 25,904 participants aged 40 years or older from the Health Examinees (HEXA) Study of the Korean Genome and Epidemiologic Study (KoGES). Each participant completed one FFQ and one-day (n=11,280) or two-day 24HR (n=14,624). We classified coffee types into: black coffee, coffee with sugar and cream, and coffee with sugar alone or cream alone. We compared the proportions of nondrinkers, black coffee, and coffee with sugar and cream through FFQ and 24HR. Results: Among those who completed one FFQ and one-day 24HR, 39.4% of "nondrinkers" on one-day 24HR reported that they did not drink coffee on their FFQs. Whereas among those who complete two-day 24HR, 71.2% of "nondrinkers" on two-day 24HR said that they did not drink coffee on their FFQs. Among those who completed one FFQ and oneday 24HR, 58.3% marked "black coffee" on one-day 24HR said that they drank black coffee on their FFQs. Among those who complete two-day 24HR, 58.8% marked "black coffee" on two-day 24HR said that they drank black coffee on their FFQs. The kappa coefficients and percent agreements were 0.4 and 59.6%, respectively, for the comparison of coffee intake between FFQ and one-day 24HR, and 0.6 and 72.8%, respectively, for the comparison of coffee intake between FFQ and two-day 24HR. Conclusions: We found discrepancies between FFQs and 24HR in the types of coffee consumed. Such limitations should be considered when using the 24HR data to examine the effect of coffee consumption on disease development.

Objectives The purpose of this study was to investigate the effect of BMI (body mass index), blood parameters and life pattern on KOQOL (Korean version of obesity-related quality-of-life scale) in Health checkup examinees of college students. Methods A group of 2992 test subjects took their medical examination. With their height and weight, we diagnosed obesity according to BMI. KOQOL was measured by survey conducted using self-report questionnaires, after excluding sexual life related question. We analysed relationship between KOQOL and BMI, blood parameters, life pattern using SPSS version 21.0. Results 1. There were significant differences in KOQOL according to BMI, gender, creatinine. 2. Female showed higher KOQOL than male. 3. Normal weight group showed lowest KOQOL in male, but underweight group showed lowest KOQOL in female. 4. Group who had more than 6 breakfast, lunch and dinner each in a week showed significantly lower KOQOL than that who didn't. Conclusions Obesity has significant influence on quality of life, so therefore there is a need for correct weight perception in weight control program, and KOQOL can be used in evaluating patients mental and social health.

Objectives: Metabolic syndrome is considered a coronary heart disease risk factor and its prevalence rate is increasing in Korea. Because obesity is relevant to metabolic syndrome, we investigated the relationship between metabolic syndrome and the Obesity Pattern Identification Questionnaire in middle-aged health check-up examinees. Methods: This was a cross-sectional study with 125 patients who visited a health promotion center of university hospital from October 2012 to January 2013. We analyzed the association of Obesity Pattern Identification Questionnaire and the diagnostic criteria of metabolic syndrome. Results: Pi deficiency (脾虛), phlegm (痰飮), liver stasis (肝鬱) and food accumulation (食積) pattern showed significantly highs score in the group with hypertriglyceridemia. Also, females demonstrated significantly high scores of liver stasis (肝鬱) and food accumulation (食積) in the group with hypertriglyceridemia. The questions of Pattern Identification that showed especially significant high score in the group of hypertriglyceridemia are as follows: 'Easily get annoyed', 'Usually worried', 'Frequently overeating or bingeing', and 'Having more after getting full'. There are positive correlations between triglyceride and the score of Pi deficiency (脾虛), phlegm (痰飮) and food accumulation (食積) pattern. Conclusions: Obesity Pattern Identification Questionnaire can be used for the management of hypertriglyceridemia in an effort to prevent metabolic syndrome.

Purpose : Obesity indices are major predictive markers for coronary artery stenosis, but there are few studies about the relationship between obesity indices and coronary artery stenosis in the Korean population. Therefore, we analyzed the association between obesity indices and coronary artery stenosis among health-screen examinees. Methods : This study included 99 males and females who visited a health-examination center. The obesity indices included body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT), visceral adipose tissue/subcutaneous adipose tissue ratio (V/S ratio). All subjects had their degree of coronary artery stenosis measured using coronary computed tomography angiography (CCTA). A multiple logistic regression test was conducted to analyze the association between obesity indices and coronary artery stenosis. Results : This study was taken by multiple logistic regression test adjusted by age, sex, smoking status, frequency of alcohol drinking/week and frequency of exercise/week. The adjusted odds ratio for the presence of coronary artery stenosis for subjects with abdominal obesity (abdominal obesity defined as a waist circumference ≥ 90 cm in males; ≥ 85 cm in females) was 6.263 (95 % confidence interval (CI) 1.974-19.869), for subjects with visceral obesity by visceral adipose tissue (visceral obesity defined as a visceral adipose tissue ≥ 100) was 11.430 (95 % CI 3.044-42.928). Conclusion : In this study of adults, WC and VAT were independent predictors of coronary artery stenosis. These results suggest that WC and VAT may be useful markers of coronary artery stenosis.

Objectives: Self-reported disease history is often used in epidemiological studies. In this study, we acquired the hospital records of subjects who self-reported stroke or myocardial infarction (MI) and evaluated the validity of the participants' self-reported disease history. We also determined the level of agreement between specialists and non-specialists. Methods: Among the participants in the Health Examinees study, 1488 subjects self-reported stroke or MI during 2012-2017, and medical records were acquired for the 429 subjects (28.8%) who agreed to share their medical information. Each record was independently assigned to 2 medical doctors for review. The records were classified as 'definite,' 'possible,' or 'not' stroke or MI. If the doctors did not agree, a third doctor made the final decision. The positive predictive value (PPV) of self-reporting was calculated with the doctors' review as the gold standard. Kappa statistics were used to compare the results between general doctors and neurologists or cardiologists. Results: Medical records from 208 patients with self-reported stroke and 221 patients with self-reported MI were reviewed. The PPV of self-reported disease history was 51.4% for stroke and 32.6% for MI. If cases classified as 'possible' were counted as positive diagnoses, the PPV was 59.1% for stroke and 33.5% for MI. Kappa statistics showed moderate levels of agreement between specialists and nonspecialists for both stroke and MI. Conclusions: The validity of self-reported disease was lower than expected, especially in those who reported having been diagnosed with MI. Proper consideration is needed when using these self-reported data in further studies.

Objectives: The association between long sleep duration and mortality is frequently attributed to the confounding influence of comorbidities. Nevertheless, past efforts to account for comorbidities have yielded inconsistent outcomes. The objective of this study was to evaluate this relationship using a large prospective cohort in Korea. Methods: The study included 114 205 participants from the Health Examinees Study, who were followed for a median of 9.1 years. A composite comorbidity score was developed to summarize the effects of 21 diseases. Using Cox proportional hazards regression, hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, cancer, and cardiovascular mortality associated with sleep duration were estimated. These estimates were adjusted for socio-demographic factors, lifestyle factors, body mass index, and comorbidity score. Additionally, a stratified analysis by subgroups with and without comorbidities was conducted. Results: Throughout the follow-up period, 2675 deaths were recorded. After all adjustments, an association was observed between a sleep duration of 8 hours or more and all-cause mortality (HR, 1.10; 95% CI, 1.01 to 1.20). However, no such association was detected in the stratified analysis for the subgroups based on comorbidity status. Conclusions: Long sleep duration was found to be associated with all-cause mortality among Koreans, even after adjusting for comorbidities. Additional studies are required to explore the mechanism underlying the association between sleep duration and major causes of mortality.

This study was conducted to evaluate the health promotion behavior level, health beliefs, and self-efficacy of individuals preparing for civil service examinations, as well as the main factors that influence their health promotion behavior. The study subjects were 290 individuals who were preparing for civil service examinations in Noryangjin, where there are a lot of private institutions that provide training for the examinations. Data were collected by questionnaire surveys conducted from December 1 to 19, 2017. With the use of SPSS ver. 23, descriptive statistics, t-tests, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted. On average, the score for health promotion behavior practice was $2.37{\pm}0.45points$, health beliefs $3.13{\pm}0.45points$, and self-efficacy $3.55{\pm}0.74points$. Health promotion behavior was significantly positively correlated with perceived severity and perceived benefits, which are sub factors of health beliefs (r=.60, p<.001; r=.55, p<.001), while it was significantly negatively correlated with perceived barriers, which are a sub factor of health beliefs (r=.32, p<.001). The factors that influenced health promotion behavior were perceived health condition and perceived barriers, and the explanatory power of health promotion behavior was 25.1% (F=13.58, p<.001). In general, respondents studied for the examinations for a long time and were under severe job pressure; accordingly, they need to have quality meals, regular exercise, and regular medical check-ups to enhance health promotion behavior to control their stress.
