Background: Skin aging can be divided into intrinsic and extrinsic processes, and occur due to several factors. Although the interest in skin youthfulness is increasing globally, research on facial skin youthfulness and lifestyle is limited. Objective: This study aimed to evaluate the association between facial skin youthfulness and biophysical facial skin parameters in Korean women over 50 years of age. We further investigated lifestyle factors that make people appear younger than their chronological age. Methods: We surveyed the essential information and lifestyle of subjects by questionnaires, and measured the biophysical parameters of the facial skin. We then performed clinical facial assessments, and the values were compared with the chronologic age. The associations between age differences, biophysical parameters, and living habits were evaluated. Results: We identified a positive correlation between age and melanin index (r=0.245, p＜0.001) and erythema index (r=0.119, p=0.002). The melanin index was statistically significantly lower in the group without regular outdoor activities (144.66±43.24 vs. 137.00±55.48, p=0.043). The melanin index and erythema index were the significant differences that defined younger perceived age than chronological age. The perceived age was younger in the group who wore a hat when performing outdoor activities than the group who did not (3.70±1.84 vs. 3.40±1.94, p=0.034). Conclusion To retain youthful skin, it is essential to reduce sun exposure, as this factor can affect the melanin and erythema indices by inducing photoaging. Therefore, avoiding the sun bia proper methods, such as wearing a hat and sunscreen during outdoor activities, is recommended to maintain skin youthfulness.

Background: Nasal bone fractures are frequently encountered in clinical practice. Although fracture reduction is simple and correction requires a short operative time, low patient satisfaction and relatively high complication rates remain issues for many surgeons. These challenges may result from inaccuracies in fracture recognition and assessment or inappropriate surgical planning. Findings from immediate postoperative computed tomography (CT) scans and those performed at 4 to 6 weeks postoperatively were compared to evaluate the accuracy and outcomes of nasal fracture reduction. Methods: This retrospective study included patients diagnosed with nasal bone fractures at our department who underwent closed reduction surgery. Patients who did not undergo additional CT scans were excluded from the study. Clinical examinations, patient records, and radiographic images were evaluated in 20 patients with nasal bone fractures. Results: CT findings from immediately after surgery and a 1month follow-up were compared in 20 patients. Satisfactory nasal projection and aesthetically acceptable results were observed in patients with accurate correction or mild overcorrection, while undercorrection was associated with unfavorable results. Conclusion Closed reduction surgery for correcting nasal bone fractures usually provides acceptable outcomes with relatively few complications. If available, immediate postoperative CT scans are recommended to guide surgeons in the choice of whether to perform secondary adjustments if the initial results are unsatisfactory. Based on photogrammetric data, nasal bone reduction with accurate correction or mild overcorrection achieved acceptable and stable outcomes at 1 month postoperatively. Therefore, when upward dislocation is observed on postoperative CT, one can simply observe without a subsequent intervention.

Health risk appraisal (HRA) is a systematic approach for collecting information regarding individual risk factors, predicting the probability of disease occurrence and death, and linking patients with interventions to promote health and prevent disease. Because the risk factors of cardiovascular disease are well established, several cardiovascular disease risk prediction models have been developed over multiple decades. The health risk appraisal prediction model of the Korean national health screening program will be revised and updated using the latest well-validated studies to reflect the current characteristics of the Korean population and to improve the effectiveness of education and behavioral modifications. It is necessary to provide various tools such as a web page and smartphone application to increase the utility of this program in the future.

In order to increase inhaled corticosteroid (ICS) use and to reduce hospitalization, emergency department visits and ultimately the economic burden of asthma, "Korean Asthma Management Guideline for Adults 2007" was developed. To assess the guideline effects on physician's ICS prescription for asthma, we conducted segmented regression and multilevel logistic regression using National Health Insurance claims database of outpatient visits from 2003 to 2010. We set each quarter of a year as a time unit and compared ICS prescription between before and after guideline dissemination. A total of 624,309 quarterly visits for asthma was observed. The ICS prescription rate before and after guideline dissemination was 13.3% and 16.4% respectively (P < 0.001). In the segmented regression, there was no significant guideline effect on overall ICS prescription rate. In multilevel logistic regression analyses, the effect of guideline on overall ICS prescription was not significant (odds ratio, 1.03; 95% CI, 1.00-1.06). In subgroup analysis, ICS prescription increased in secondary care hospitals (odds ratio, 1.15; 95% CI, 1.02-1.30) and in general hospitals (odds ratio, 1.10; 95% CI, 1.04-1.16). However, in primary clinics, which covered 81.7% of asthma cases, there was no significant change (odds ratio, 0.98; 95% CI, 0.94-1.02). From the in-depth interview, we could identify that the reimbursement criteria of the Health Insurance Review and Assessment Service and patient's preference for oral drug were barriers for the ICS prescription. The domestic asthma clinical guideline have no significant effect on ICS prescription, especially in primary clinics.

High participation rates are important for maximizing the effects of a health screening program. Previous studies have suggested that individual or regional characteristics have effects on health behaviors. In this study, we investigated the determinants of participation in the National Screening Program for Transitional Ages by simultaneously analyzing individual and area-level factors by multilevel analysis. A total of 1,081,216 subjects, aged 40 and 66 yr and nested in 254 areas, were included. There was a significant variation in participation rates across the areas even after adjusting for individual and area-level variables. Among the individual-level variables, increasing age, sex, higher income, and mild disability grade were associated with a higher participation rate. In urban areas, the 40-yr-old group had higher participation rates than the 66-yr-old group. Deprived areas had significantly high participation rates for both age groups. The number of screening centers per 1,000 inhabitants had no significant effect on participation in the screening program. In conclusion, regional characteristics are associated with participation rates independent of personal features and regional factors have differential effects with respect to age. A multi-dimensional approach is recommended to promote participation in health screening programs.

BACKGROUNDS: The Third Report of the Adult Treatment Panel (NCEP-ATP III) has newly introduced the clinical diagnosis guideline of the metabolic syndrome which is characterized by clustering of the CHD risk factors. The purpose of this study was to estimate the prevalence of the metabolic syndrome in Korean adults by the newly introduced guideline and to evaluate possible risk factors with the syndrome. METHODS: The subject of this study included 3,873 adults (males 2,144, females 1,729) aged 20 years or older who visited the Health Promotion Center of SNUH. Among the subjects, we excluded those who did not have records of physical parameters, blood test results and who were on current medications except antihypertensives and oral hypoglycemic agents. We estimated the prevalence of the metabolic syndrome in Korean adults according to the ATP III waist-circumference guideline, Asia-Pacific waist- circumference, and Body Mass Index (BMI), respectively, and calculated the age-adjusted prevalence of the metabolic syndrome using the direct standardized method. While applying the Asia-Pacific waist circumference, we estimated the prevalence of the metabolic syndrome by age group and the prevalence of the individual abnormalities of the metabolic syndrome. To identify variables associated with the metabolic syndrome, we used the multiple logistic regression method to estimate the prevalence odds ratios for the metabolic syndrome vs. the non-metabolic syndrome. RESULTS: The age-adjusted prevalence of the metabolic syndrome in Korean adults was 9.3% when ATP III waist-circumference was applied, 15.4% for Asia-Pacific waist-circumference, and 18.6% for body mass index (BMI). The highest prevalence of the individual criteria among the metabolic syndrome diagnostic criteria in men was hypertension, followed by hypertriglyceridemia, abdominal obesity, high fasting blood glucose, and low HDL-cholesterolemia. And in women, it was also hypertension, followed by abdominal obesity, low HDL- cholesterolemia, hypertriglyceridemia, and high fasting blood glucose. The prevalence increased from 3.8% among participants aged 20 through 29 years to 27.1% for ages 60 through 69 years and 31.6% for ages above 70 years. Females, increasing age, increased BMI, current smoking, physical inactivity were higher risk factors for the metabolic syndrome, but mild drinking was a lower risk factor for the metabolic syndrome. CONCLUSION: These results show that the metabolic syndrome is highly prevalent although less prevalent than in American adults. The family physician should focus on the screening and comprehensive management of the metabolic syndrome.

BACKGROUND: There is a lack of data on Korean average VO2max values. This study attempted to yield average values of VO2max corresponding to each age group of Koreans. This study was also designed to investigate the factors associated with VO2max. METHODS: From May 1st 1996 to January 30th 2000, we recruited 21,458 subjects who visited the health promotion center at one university hospital. We obtained the data related to age, exercise by self-administered questionnaire and weight, height and blood pressure by instrumental measurements and hemoglobin, cholesterol by overnight fasting blood sampling. VO2max was estimated by submaximal bicycle ergometer test. RESULTS: The number of research subjects was 21,458: males 12,646 (58.9%) and females 8,812 (41.1%) and the average age was 48.6 (SD: ?10.05) years with age span from 20 to 79 years. The average VO2max was 26.4 (SD; ?6.77) (ml/kg/min) for men and was 19.8 (SD; ?5.94) (ml/kg/min) for women. Relating to factors such as age, VO2max, SBP, DBP, cholesterole, Hb, and body mass index, there were significant statistical differences between sex (p<0.05). For both sexes, VO2max decreased as age, cholesterol, BP and BMI increased. Regular exercise group showed significantly a higher VO2max than non-exercise group for both sexes. CONCLUSION: The average VO2max values for Koreans, according to sex and age group are reported in this study. The decreasing VO2max may be attributed to increasing age, BP, cholesterol, BMI and non-exercise.

BACKGROUND: Because of improvement of economic state and eating habit changes in Korea, 60-70% of gallbladder stones are cholesterol stones. As ultrasonography was used increasingly, detection of asymptomatic gallstone were increased. There has been few studies about asymptomatic gallstone in Korea. So, this study was designed to obtain associated factor of prevalence of asymptomatic gallstone. METHODS: We screened adults over 20 years who were visited the health Promotion Center in a university hospital from May 1995 to May 1999. Subjects were defined as case group(584 subjects) who were diagnosed gallstone by abdominal ultrasonogaphy by radiologist. Control group(1153 subjects) were selected by random sampling from visitors of the Health Promotion Center. Every subjects were assessed with respect to gender, age, height, weight, fasting blood glucose, serum total cholesterol, high density lipoprotein-cholesterol, triglyceride. Social-Economic state, smoking were assessed by self-administered questionnaires. Associated factor of prevalence of asymptomatic gallstone were analyzed by Chi-square test and multiple logistic regression. RESULTS: Age, BMI(Body Mass Index), fasting blood glucose were associated with gallstone by Chi-square test(P<0.05). Multiple logistic regression showed that prevalence of asymptomatic gallstones was increased by age(>40 years old) and were associated with BMI(>25 kg/m2), fasting blood glucose. CONCLUSION: Associated factors of prevalence of asymptomatic gallstone were increased by age(>40 years old) and were associated with BMI(>25 kg/m2), fasting blood glucose, and were not different from those in West countries. further studies will be needed about associated factors according to the composition of gallstone and developing from asymptomatic gallstone to asymptomatic gallstone.

BACKGROUNDS: The education by the family physician. is important for more practical primary care medicine education. In this study, we try to know the presnent state of education and the future and the number of education resource and how to multiply this resource. METHODS: we have got the list of family physicians who have their clinic in Seoul by the help of the Korean Academy of Family Medicine. And we performed telephone questionary. We also asked the demographic factors RESULTS: 134 persons were asked questionary by the telephone. 17persons were joining in education. Trainee by the 3rd grade hospitals was the major, the next was by 2nd grade hospital, and doctors who did not have the training. 14 persons have begun education by asking of the training hospital, 3 persons wanted it, but none thought it beneficial to them. 44 persons wanted to join education in the future, and there was no difference between the 3rd and the 2nd grade hospital trainee. CONCLUSION: There was no difference between the 3rd and 2nd grade hospital trainee but 2nd grade hospital trainee was less joining than the 3rd. This shows that the 2nd grade hospital trainee can be the good pool of the future education if there are adequate supply. So many adequate supply is necessary.
