The aim of this study was to examine the impact of the obesity status on serum uric acid in health check-up examinees. The study subjects were 1,118 adults, 20 years and over (636 males, 482 females), the health package check-up at the general hospital in Gwang-Ju from January to December, 2011. This study assessed the serum uric acid, blood urea nitrogen, and creatinine levels, as well as the anthropometric variables (SBP, DBP, and BMI). In a model I, after adjusting for the variables, such as age, SBP, DBP, TC, TG, HDL-C, and FBG, the mean uric acid level ($M{\pm}SE$) increased with increasing obesity status in males (p<0.001) or females (p=0.036). In model II, after adjusting for BUN and creatinine, the mean uric acid ($M{\pm}SE$) in males increased with increasing obesity status (Normal weight [BMI <$23.0kg/m^2$], $4.89{\pm}0.07mg/dl$; overweight [BMI $23.0-24.9kg/m^2$], $5.01{\pm}0.09mg/dl$; obesity [BMI ${\geq}25.0kg/m^2$], $5.35{\pm}0.08mg/dl$) (p<0.001). In the females, however, the mean uric acid ($M{\pm}SE$) did not increase with increasing obesity status (Normal weight, $5.03{\pm}0.08mg/dl$; overweight, $5.19{\pm}0.11mg/dl$; obesity, $5.27{\pm}0.09mg/dl$) (p=0.191). In conclusion, these results suggest that an increase in obesity status is associated with an increase in the serum uric acid levels in males, but not in females.

Purpose : This study aimed to assess the prevalence of obesity, hypertension, and hyperlipidemia in children from low-income families in Gunpo and to evaluate whether economic status affects the prevalence of obesity. Methods : Between October 2007 and March 2008, 341 children (167 girls and 174 boys; age, 6 to 13 years) were enrolled in this study. All these children came from families who earned minimum wages and who were supported by government. We measured height, weight, and blood pressure and performed laboratory examinations, including total cholesterol, high-density lipoprotein cholesterol, and triglycerides. Body mass index (BMI) was calculated using weight and height. We compared the prevalence of obesity, hypertension, and hyperlipidemia in children from low-income families with the prevalence of these maladies found in other studies. Results : Prevalence of obesity ($BMI{\geq}95^{th}$) was 7.1%. Prevalence of hypertension and hyperlipidemia was 8.2% and 16.7%, respectively. In the obese group, prevalence of hypertension and hyperlipidemia was 25.0% and 45.8%, respectively. Obesity and hyperlipidemia were slightly more frequent in our study than those found in other reports, and the prevalence of hypertension in the obese group was very high compared with statistics from the Korean National Health and Nutrition Examination Survey (25% vs. 19.5%) and those from other reports. Conclusion : Low-income status was associated with an increased incidence of obesity, hyperlipidemia, and hypertension. Hypertension showed an especially strong association with economic status, which seemed to correlate with genetic, environmental, and dietary effects.

Kidney stones are a common disease with an annual prevalence of about 30,000 people in Korea, and are deeply related to an increase in chronic kidney disease, high blood pressure, coronary artery disease, metabolic syndrome, type 2 diabetes, hyperlipidemia, and abdominal obesity. Therefore, in this study, 135 examinees who visited a general hospital in Dalseong-gun from May 2019 to June 2020 for a medical examination were examined. The relationship between kidney stones and factors related to obesity and metabolic syndrome were found in abdominal ultrasound. I tried to find out the relevance. As a result of the study, the risk of kidney stones in the abnormal group was increased by 4.255 times compared to the normal group in total cholesterol factor, and the risk of kidney stones in the abnormal group was increased by 2.072 times compared to the normal group in the low-density lipoprotein cholesterol factor. Total cholesterol factor and low-density lipoprotein cholesterol It was found that the factor affects the prevalence of kidney stones and metabolic syndrome. Since the risk of kidney stones is related to total cholesterol and low-density lipoprotein cholesterol factors, active attention should be paid to preventive purposes through health check-ups.

Objectives: The purpose of this study was to evaluate the relationship of nonalcoholic fatty liver and cardiovascular risk factors. Methods: This study was conducted to investigate the association of nonalcoholic fatty liver and cardiovascular risk factors for adult men (n=2976) and women (n=2442) who were over 19 years old, after excluding the HBsAg(+) or anti-HCV(+) patients and the men and women with increased alcohol intake (men: 40g/week, women: 20g/week). Results: Compared with the normal liver subjects, the nonalcoholic fatty liver subjects showed a significantly increased frequency of abnormal systolic blood pressure (${geq}120mmHg$), fasting blood sugar (${\geq}100mg/dL$), total cholesterol ($({\geq}200 mg/dL$), triglyceride ($({\geq}150mg/dL$), high density lipoprotein cholesterol (<40 mg/dL), low density lipoprotein cholesterol ($({\geq}130g\; m/dL$) and abdominal obesity in men, and all these measures were significantly increased in the women except for abnormal HDL cholesterol. After adjusting for the body mass index, age, smoking, exercise and a nonalcoholic liver, the odds ratios of an abnormal waist hip ratio were 1.35(95% Confidence Interval=1.05-4.72) in the mild fatty liver, 1.61 (1.19-2.18) in the moderate fatty liver, 2.77(1.57-4.92) in the severe fatty liver compared with a normal liver. The adjusted odds ratios for abnormal fasting blood sugar were 1.26(1.03-1.53) in the mild fatty liver, 1.62(1.27-2.06) in the moderate fatty Iiver and 1.77(1.12-2.78) in the severe fatty liver. The adjusted odds ratios for abnormal triglyceride were 1.38(1.11-1.72) in the mild fatty liver, 1.73(0.33-2.24) in the moderate fatty liver and 1.91 (1.17-3.10) in the severe fatty liver of men. Adjusted odds ratios for abnormal triglyceride were 1.50(1.04-2.15) in mild, 1.71(1.07-2.68) in moderate, 1.81(0.69-4.38) in severe fatty liver of women. Conclusions: The nonalcoholic fatty liver subjects had more cardiovascular risk factors compared with the normal liver subjects. Thus, prevention and treatment of the nonalcoholic fatty liver is necessary by lifestyle modifications such as restriction of alcohol intake, no smoking, exercise and adequate eating habits.

The purpose of this study was to obtain the serum lipid levels according to the lifestyles, and examine the influence of lifestyles on the serum lipid levels among adults who examined the health checkup in an university hospital. The subjects for this study were 4,112 adults who underwent medical examinations at the health center of a university hospital in Daejeon city from Jan 2012 to Dec 2013. The lifestyles and serum lipid levels of study subjects were obtained from self-recorded questionnaires and medical examination charts of the hospital. As a result, the mean values of the serum lipid levels (TC, HDL-C. LDL-C and TG) and atherogenic index (AI) of the study subjects showed a significantly difference according to the lifestyle, such as age, alcohol consumption, smoking, regular exercise, overeating and meat consumption in both sexes. The TC, HDL-C. LDL-C, TG and AI showed a positive correlation with age, AUDIT score, but the HPI score showed a negative correlation in both sexes. In the age-adjusted odds ratio, the risk ratio of an abnormality of TC, HDL-C. LDL-C, TG and AI increased significantly because there was an increase in the group of everyday overeating and meat consumption, smoking group, no exercise group, and low HPI group than their respective counterparts in both sexes. The above results suggested that the serum lipid levels of the subjects was closely related to increasing age, and lifestyles, such as alcohol consumption, smoking, regular exercise, overeating, and meat consumption.

Recently, there has been prevailing of the combined utilization (CU) with herbs and prescribed drugs in medical therapies in the world. But the information about frequency, efficacy and safety of this CU has not well known in Korea, yet. This study aimed to identify the status of CU by Koreans, and to inquire which side effects of CU represent to those people. A self-completed questionnaire survey was performed through each health examination center in twenty general hospitals and one oriental hospital. Of the initial 2,100 health examinees, 1,851 were participated in this survey, resulting in a response rate of 88.1%. The proportion of CD was 26.3%. The most commonly mentioned reason of CD was 'to promote general health and well-being' (17l persons, 35.5%). The main route of taking CD was self-purchase at drugstore or at herbs market, followed by the prescription of (oriental)physicians. 33.0% (151 persons) of those who took the CD rated it as effective. 93 respondents (19.8%) were experienced several adverse effects including nausea, fatigue, and dizziness. The growing simultaneous use of herbal products and pharmaceutical drugs by Korean consumers may be continuously increased the risk of herb-drug interactions. The medical professionals should be provided with comprehensive and up-to-date information about potential benefits and risks of herbs and prescribed drugs. In the future studies it may be recommended to deal common cold, health promotion, indigestion, headache, and hypertension for the effect and safety of the CD by well-organized prospective study design.

The importance of repeat screening for stomach cancer is well known to decrease deaths from stomach cancer. This study was aimed at assessing practice behaviors and to identify related factors in the aspects of demographic factors, health status and cancer risk recognition, attitude to cancer screening, health behaviors, and inhibiting or facilitating factors to stomach cancer screening in an urban area. Data was collected through self-administered questionnaires from 403 people aged 40 to 69 years from April 23th to May 15th, 2002. Practice behaviors were classified as : "ever" or "never", and "repeat" or "not repeat" grouped based on a recent 5 year screening history. The results were as follows: 1. Among the 403 subjects: "the ever group" was 23.8% and "the repeat group" was 4.0%, The rates of screening were 20.5% for men, 27.8% for those women, and 27.3% for aged 40-49, 24.5% for those aged 50-59, 19.0% for those aged 60-69. The rates of repeat screening were 4.0% for men, 4.1% for women, and 2.9% for those aged 40-49, 6.3% for aged 50-59, 2.5% for those aged 60-69. 2. The main factors associated with adherence to gastric cancer screening were education(post high school vs below : OR=2.44), previous cancer screening(yes vs no : OR=2.61), belief in personal health(no vs yes : OR=2.72), health status(unhealthy vs healthy : OR=3.40), possibility of cancer compared to others(low vs not low : OR=2.56), and regular exercise(yes vs no : OR=2.94). The main factor associated with adherence to gastric cancer repeat screening was other cancer screening(yes vs no : OR=6.33). Consequently, there is a need to change the recognition of the importance and necessity of stomach cancer screening in healthy conditions through health education, and to perform multiple screening tests each visit.

This study examined the impact of osteoporosis on thyroid hormone in health check-up examinees. The study subjects were 1,117 adults, 20 years and over (636 males, 481 females), who underwent a health package check-up at the general hospital G from January to December, 2011. After adjusting for factors, such as year and gender, the mean thyroid stimulating hormone increased with decreasing T-score (Normal[${\geq}-1g/cm^2$], $1.61{\pm}0.07{\mu}IU/m{\ell}$ and osteopenia[-1 >, ${\geq}-2.5g/cm^2$],$1.82{\pm}0.08{\mu}IU/m{\ell}$ and osteoporosis[< $-2.5g/cm^2$],$3.14{\pm}0.27{\mu}IU/m{\ell}$). After adjusting for factors, such as gender and FBS, the mean free thyroxine decreased with decreasing T-score(Normal, $1.30{\pm}0.01ng/d{\ell}$, and osteopenia, $1.22{\pm}0.01ng/d{\ell}$, and osteoporosis, $1.13{\pm}0.04ng/d{\ell}$). Conclusion. These results suggest that a decrease in T-score might increase the thyroid stimulating hormone and decrease the free thyroxine levelin euthyroid adults.

In this study, standard model of medical radiation dosage quality control system will be suggested and the useful of this system in clinical field will be reviewed. Radiation dosage information of modalities are gathered from digital imaging and communications in medicine(DICOM) standard data(such as DICOM dose SR and DICOM header) and stored in database. One CT scan, two digital radiography modalities and two mammography modalities in one health promotion center in Seoul are used to derive clinical data for one month. After 1 months research with 703 CT scans, the study shows CT $357.9mGy{\cdot}cm$ in abdomen and pelvic CT, $572.4mGy{\cdot}cm$ in brain without CT, $55.9mGy{\cdot}cm$ in calcium score/heart CT, screening CT at $54mGy{\cdot}cm$ in chest screening CT(low dose screening CT scan), $284.99mGy{\cdot}cm$ in C-spine CT and $341.85mGy{\cdot}cm$ in L-spine CT as health promotion center reference level of each exam. And with 1955 digital radiography cases, it shows $274.0mGy{\cdot}cm2$ and for mammography 6.09 mGy is shown based on 536 cases. The use of medical radiation shall comply with the principles of justification and optimization. This quality management of medical radiation exposure must be performed in order to follow the principle. And the procedure to reduce the radiation exposure of patients and staff can be achieved through this. The results of this study can be applied as a useful tool to perform the quality control of medical radiation exposure.
