Objectives: The purpose of this study is to investigate the impact of health behaviors of male workers without diabetes such as smoking, drinking and physical activities on HbA1c using 2015 and 2016 data from Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The final study subjects of KNHANES were a total of 1,703 male workers in their 30s-50s who had normal levels of fasting blood sugar level, HbA1c, and hemoglobin. For the study variables, age, household income, educational level and occupation were included as socio-demographic characteristics; smoking behavior, drinking behavior, and physical activity behavior as characteristics of health behavior; and waist circumference, body mass index, systolic and diastolic blood pressures, total cholesterol, triglyceride and HDL cholesterol as medical examination characteristics were included. The analysis was conducted using independent variables t-test, one-way ANOVA, Pearson's correlation analysis and multiple regression analysis. Results: Socio-demographic factors that affect HbA1c were age, educational level, and occupation. As for HbA1c according to the status of current smoking, it was higher in order of the present, past and nonsmoking and HbA1c according to smoking amount pack-year increased linearly in between less than 1 pack-year and over 30 pack-year (p<0.001). Muscular exercises affected the reduction of HbA1c (p<0.05). In the multiple regression analysis with independent variables of the socio-demographic characteristics and health behavior, factors affecting HbA1c were age, occupation and smoking amount pack-year (p<0.05). In the multiple regression analysis where the characteristics of physical examination were added, factors affecting HbA1c were age, occupation, smoking amount pack-year, waist circumference and total cholesterol (p<0.001). Conclusions: As a result, the health behavior that had the most effect on HbA1c management for male workers without diabetes was the total lifetime smoking amount. Therefore, it is essential to prevent smoking as well as control, cholesterol to prevent diabetes for male workers.

Background: In chronic hepatitis B (CHB), the presence of hepatic steatosis (HS) seems to be associated with known host and viral factors which may influence the long-term prognosis of chronic hepatitis B (CHB), probably leading to cirrhosis and hepatocellular carcinoma (HCC). Different from chronic hepatitis C (CHC), factors associated with HS in CHB are not clearly explored. Materials and Methods: 160 CHB patients were divided into two groups depending on the results of liver biopsy. Group I consisted of 71 patients with confirmed steatosis. Group II comprised 89 patients without steatosis. The groups were compared in terms of basal characteristics, body mass index (BMI), liver enzymes (ALT, AST, ALP), serum fasting blood sugar (FBS) and lipids, hepatitis B e antigen (HBeAg), viral load, and histological findings. Results: In terms of host factors, male gender, older age, BMI, high serum FBS and lipid levels were associated with HS. On the other hand, ALT levels, the HAI scores of necroinflammation and stage of fibrosis did not associate with HS. On multivariate analysis, parameters of sex, BMI, cholesterol and FBS levels were independently associated with HS. Regarding viral factors, HBeAg negativity was significantly associated with HS (81.7%, p value 0.006), but not HBV DNA level (p value 0.520). Conclusions: HS in CHB appears to be unrelated to the status of HBV replication. However, fibrosis progression in CHB is related to variable host factors. HS may be enhanced through these factors in HBV chronic patients.

This study was conducted to identify the effects of a planned exercise program based on Bandura's self efficacy model on metabolism, and the exercise compliance in type 2 diabetes mellitus patients. The study design was a nonequivalent pre-test post-test control design. Thirty four type 2 diabetes mellitus patients, who received follow-up care regularly through the diabetic out-patient clinic, were randomly sampled for this study. Twenty patients were assigned to the experimental group and fourteen patients were assigned to the control group. In the experimental group, a planned exercise program is composed of an individualized exercise prescription for 12 weeks, an individual education, and even a telephone coach program. In the case of the control group, they were instructed to continue with their usual schedules. The data collection period was from March 1999 to February 2000 Data were analyzed using SPSS/WINDOW 10.0 program. The results were as follows. 1. In the experimental group, the level of fasting blood sugar has significantly decreased from 188.20 mg/㎗ to 155.55 mg/㎗ after planned exercise program (F= 16.86, p=.000). For lipid metabolism, body fat per cutaneous decreased from 27.16% to 26.57% after planned exercise program. The score of self efficacy has increased from 64.20 to 66.65 after planned exercise program and it was statistically significant (F=4.850, p=.040) The functional vital capacity has increased from 3.28$\ell$ to 3.37$\ell$and it was statistically significant(F=7.300, p=.020). 2. In an after effect of a planned exercise program, 35 percent of the subjects who participated in a planned exercise program continued to exercise for another six months. In conclusion, the planned exercise program can improve cardiopulmonary function, glucose, and lipid metabolism. This program was show a positive effect on the self efficacy and exercise compliance.

Purpose: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. Materials and Methods: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. Results: The mean age was $52.0{\pm}4.7years$, and the mean PSA was $0.97{\pm}0.99ng/mL$. The PSA showed a significant positive correlation with the age (r=0.108, p<0.01), TPV (r=0.349, p<0.01), height (r=-0.052, p<0.05), weight (r=0.186, p<0.05), low-density lipoprotein cholesterol (r=0.056, p<0.05), and GFR (r=-0.096, p<0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=-0.013, p<0.001; beta=-0.039, p<0.001; and beta=-0.010, p=0.005; respectively) in age and TPV-adjusted model. Conclusions: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.

Purpose: This study aimed to apply a health partnership program using commercially available mobile health apps to improve cardiovascular risk factors in male employees and verify its effectiveness. Methods: Using a randomized control group pretest-posttest design, male employees with cardiovascular risk factors from five small and medium-sized workplaces were randomly assigned to an experimental group (n = 32) and a control group (n = 31). The experimental group was encouraged to use three mobile health apps for 12 weeks to acquire the necessary cardiovascular disease-related information and practice strengthening training, walking, and diet management appropriate to their level. They also received feedback on their weekly activities and motivational text messages from health partners. Hypotheses were tested using the SPSS WIN 22.0. Results: The experimental group showed a significant difference compared to the control group in terms of their perception of mobile health app (p < .05), self-efficacy for exercise and diet, self-management partnership, and cardiovascular disease prevention health behavior (p < .001). In particular, there were significant decreases in the body mass index, ratio, serum fasting blood sugar, total cholesterol, and triglyceride in the experimental group (p < .001); however, there was no significant difference in high-density lipoprotein-cholesterol. Conclusion: Intervention using mobile apps based on partnership with health managers is effective in improving the objective cardiovascular risk index in male employees; therefore, such intervention should be continuously used as a useful lifestyle modification strategy in the workplace.

To improve wellness and quality of life by recognizing the health efforts of stress, the author estimated the relationships between stress, subjective symptoms and clinical diagnosis through a questionnaire and a battery of specified laboratory tests; electrocardiography, blood pressure, cholesterol, aspartate aminotransferase(AST), alanine aminotransferase(ALT), gamma glutamyl transferase$(\gamma-GTP)$, fasting blood sugar, gastro-endoscopy or UGI, abdominal sonography, etc. The data was gathered from 337 clients who were undergoing multiphasic screening program at a University Hospital from January to March 1998. The mean age of subjects was $46.5{\pm}11.2$ years and the mean of body mass index was $24.0{\pm}3.7kg/m^2$. The mean vol of stress was $18.5{\pm}6.0$ expressed as the score out of 40. By general characteristics and lift style among male, mean level of stress was significantly higher in case of lower socioeconomic status, habitual drug use, longer daily working time(>10 hours), no regular exercise, drinkers, irregular meal, skip-ping breakfast(p<0.05). In case of female, that was significantly higher in case of lower education, lowe. socioeconomic status, longer daily working time(>10 hours), no regular exercise, drinkers, smokers, irregular meal, skipping breakfast(p<0.05). Significant correlations were observed between stress and subjective symptoms in all kinds of organ system (p<0.01). Correlation coefficients of stress among male were relatively high with neuro-psychiatric symptom$(\gamma=0.476)$ and cardio-vascular symptom$(\gamma=0.361)$ in order, and correlation coefficients of stress among female was highest with neuro-psychiatric symptom$(\gamma=0.371)$. The prevalence of the diagnosis through the battery of laboratory tests was high in upper gastrointestinal disorders and hypercholesterolemia in order in both sex group. Among male the mean score of stress was significantly high in ulcerative peptic disorder of upper gastrointestine and hepatopathy in order (p<0.05) . Among female that was significantly high in diabetes mellitus. In summary, it is likely that there are associations between stress, subjective symptoms and clinical diagnosis. To promote wellness and quality of life it would be of value that periodic stress evaluation program and stress management including apropriate control of smoking and drinking, regular exercise and meal.

Objectives This study was performed to evaluate the relation between hair tissue mineral elements(HTME) and Heart rate variability(HRV) of the metabolic syndrome(MS). Methods 89 persons(41-69 ages) who visited Oriental hospital for medical examination were divided MS group(n=22) and control group(n=67). HTME and HRV were compared, and were analyzed correlation with five contents of the MS. Results (1) In total subjects, waist circumference had a positive correlation with Pb. Blood pressure had a negative correlation with Mg. High density lipoprotein cholesterol(HDL-chol) had a negative correlation with Pb, Sb and K, while positive correlation with Ca/K. Triglyceride(TG) had a negative correlation with Mg and Na/K, while positive correlation with K and Ca/Mg. (2) In total subjects, TG and fasting blood sugar(FBS) had negative correlation with high frequency(HF), while positive correlation with low frequency/high frequency ratio(LF/HF). (3) In MS group, most of the level of toxic minerals were higher, and the level of major nutritional minerals were lower, but there were no statistical signficance. In two groups, there is no contrast between the correlations of the MS contents and HTME. (4) In MS group, HF was significantly lower and LF/HF was higher than normal group. LF/HF had a negative correlation with waist circumference in MS group, while positive correlation in normal group. (5) In total subjects, TP had a positive correlation with Mg. In two groups, there is no contrast between the correlations of the MS contents and HRV. However LF/HF had a positive correlation with Na in MS group, TP and LF had negative correlation with Ca, while RMSSD and HF had negative correlation with Cu in normal group. Conclusion These results may suggest that HTME and HRV are useful in diagnosing and preventing the metabolic syndrome.

Objectives : This study was conducted to examine the association between the carotid artery intima-media thickness (IMT), plaque and cardiovascular risk factors according to gender and age. Methods : The data used for this study were obtained from 1,507 subjects (691 men, 816 women), aged 20-74 years, who participated in 'Prevalence study of thyroid diseases' in two counties of Jeollanam-do Province during July and August of 2004. The body mass index (BMI) and waist hip ratio (WHR) were calculated by anthropometry The blood pressure, pulse rate, pulse pressure, total cholesterol, triglyceride, HDL cholesterol and fasting blood sugar level were also measured. Ultrasonography was used to measure the carotid artery IMT and plaque. IMT measurements were performed at 6 sites, including both common carotid arteries, and the bulb and internal carotid arteries. The definition of the 'mean IMT' was mean value obtained from these 6 sites. Results : The ${\pm}$ standard deviation IMT values were $0.65{\pm}0.14\;and\;0.60{\pm}0.13mm$ in men and women (p<0.001), respectively. The data were analyzed according to gender and the 50 year age groups. In a multiple linear regression analysis, age and hypertension were positively associated with the mean IMT in both men and women, aged<50 years. Age, total cholesterol and smoking (current) were positively associated with the mean IMT in men $(\geq50\;years)$. Age was positively associated with the mean IMT in women $(\geq50\;years)$, but the HDL cholesterol level was negatively associated. The prevalence of plaques was 44.2%(196/443) in men and 19.4%(89/459) in women, for those greater than 50 years of age. In a multiple logistic regression analysis, age (OR=1.090, 95%CI=1.053-1.129), HDL cholesterol (OR=0.964, 95%CI=0.944-0.984), total cholesterol (OR=1.009, 95%CI=1.002-1.017)and BMI (OH=0.896, 95%CI=0.818-0.983) were independently associated with plaques in men; whereas, age (OR=1.057, 95%CI=1.012-1.103), HDL cholesterol (OR=0.959, 95%CI=0.932-0.986), pulse pressure (OR=1.029, 95%CI=1.007-1.050) and triglycerides (OR=0.531, 95%CI=0.300-0.941) were independently associated with plaques in women. Conclusions: There were significant gender and aging differences in the association between the IMT, plaque and cardiovascular risk factors. Therefore, for the prevention of atherosclerosis, selective approaches should be considered with regard to gender and age factors.
