The purpose of this study is to analyze health behavior by comparing the difference between self-perceived health status and health examination results. The study subjects consist of 7,702 people aged over 20, surveyed by Health Interview survey, Health Examination survey, Dietary Life survey, Health Consciousness and Behavior survey. Data used in the study are drawn from raw data from a 1998 National Health and Nutrition survey. General characteristics variables are sex, age, education level, residential area, marital status, occupation, and living standard while dichotomous variables, ‘not healthy’ and ‘healthy’ are used to measure self-perceived health status. Variables for health examination results are high blood pressure, high cholesterol, diabetes, liver diseases, liver inflammation, kidney diseases, normal weight, regular diet, optimum sleeping time(7-8 hours), regular health examination and health behavior practice group. Major findings of the study are as follows: 1) Analysis of self-perceived health status and health behavior by disease: Variables significantly correlated with high self-perceived health status have strong associations with high health behavior practice, which supports the hypothesis that as one has high self-perceived health status, one is more likely to practice health promoting behavior. The results of analysis of health behavior differences by dividing subjects into two categories, ‘cases of illness’ and ‘cases of no illness’ indicate that drinking, sleeping time, health examination are significant variables (p〈0.001, 0.05) whereas smoking, weight control, regular exercise, regular diet are not significant. 2) Analysis of disparity patterns between self-perceived health status and health examination: The hypothesis that health behaviors would be different according to the disparity pattern between self-perceived health status and health examination is supported as a result of χ2 test. Among Type I : Self-perceived health status is high and actual health status is good (no disease) Type II: Self-perceived health status is high and actual health status is poor(have disease) Type III: Self-perceived health status is low and actual health status is good(no disease) Type IN: Self-perceived health status is low and actual health status is poor(have disease) Type I and Type IV show no disparity, Type I shows the highest health promoting behavior whereas Type IV shows the lowest health promoting behavior. Type II, and III, compared to Type I, practise lower health promoting behavior. Multi-logistics regression analysis was conducted to find out the degree of impact on health behavior. Independent variables are general characteristics, self-perceived health status and health examination result and presence of illness, while the dependent variable is health promoting behavior. The analysis of the impact of self-perceived health status on the health promoting behavior shows that smoking, drinking, weight control, regular exercise, health examination practice, and/or regular diet are significantly correlated to self-perceived health status. High self-perceived health status is inversely related to high health promoting behavior. This finding supports the hypothesis that the higher one perceives one's health, the more likely one is to practice health promoting behavior. On the contrary, the presence of illness has little impact on health promoting behavior. 3) Multiple logistics analysis on how disparity patterns between self-perceived health status and health examination affect health behavior: The results of multiple logistics analysis made on health behavior variables compared to the standard variable are as follows: When analyzed on the standard of Type I, smoking is a significant risk factor for the Type IV. In case of drinking, all the patterns show a high probability of relative risk ratio. With regard to weight control, it is a risk factor for Type II while all the patterns show high probability of not practising when analyzed on the standard of type IV. Type III and IV show high probability of not doing regular exercise while Type IV, shows a high probability of not taking appropriate sleeping time. When analyzed on the standard of type IV, all the patterns show a high probability of not taking health examinations. Type III and IV show a high probability of not having regular meals. As for overall health promoting behavior, Type III and IV show a high relative risk ratio. These two groups have low self-perceived health status. It implies that self-perceived health status has significant impact on health promoting behavior. This is also supported by the fact that Type I with high self-perceived health status and no illness shows a high practice rate of health promoting behavior. Types II and III the groups with high disparity between self-perceived health status and health examination results, show a low practice rate of health promoting behavior when compared to Type I. Type IV, that is the group with low self-perceived health status and actual illness, shows the lowest practice of health promoting behavior. It is highly probable that this type proves to be the poorest health group.

Purpose: This study was conducted for comparison of salty taste assessment, salty taste preference, high-salt dietary attitude, and high-salt dietary behavior by stages of behavior change among school-aged children and adolescents. Methods: A total of 1,595 students (1,126 school- aged children, 469 adolescents) from 43 elementary schools and 17 middle and high schools in Daegu were tested using salty taste kits and surveyed using questionnaires on stages of behavior change, high-salt dietary attitude, and behavior. Results: Adolescents showed a significantly higher result for salty taste assessment than school-aged children (p < 0.01). In salty taste assessment, the students of pre-contemplation stage (n = 498) and contemplation stage (n = 686) showed higher scores than students of action stage (n = 351) and maintenance stage (n = 60). Regarding the salty taste preference, students of maintenance stage preferred the lower two samples (0.08%, 0.16%) and students of pre-contemplation stage preferred the higher two samples (0.63%, 1.25%). High-salt dietary attitude scores and dietary behavior scores were highest for students of pre-contemplation stage and were lowest for students of maintenance stage. Conclusion: Salty taste assessment, high-salt dietary attitude, and high-salt dietary behavior were significantly different by stages of behavior change among school-aged children and adolescents. This study suggests the need for examination of the stages of behavior change before nutrition education for effective education.

We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.

Objectives: This study is designed to suggest the health service goals necessary for providing the more efficient services relevant to the requests of the community, through the evaluation on the operating status of the unified health subcenters. Methods: We visited total 5 unified health subcenters comprising 3 ones located in Gyeongsangbuk-do and 2 ones located in Gyeongsangnam-do from December 2000 to January 2001, and interviewed about the pre- and post-unified status related to manpower, facilities, equipment, medical service and health service quality, and the problems and improvement plans of the unified management. Results: According to the evaluation on the manpower before and after the unification of the health subcenters, the total employees increased by 2.8 persons on average from 6.8 to 9.6 persons in the investigated subjects. The numbers of doctors, dentists and nurses were almost the same as before. There were no clinical pathologic technician and radiological technician before but they were appointed to duty in 3 unified health subcenters later. The unification of the health subcenters has produced slight increases in the frequency of the medical service and dental treatment and considerable increases in that of the physical therapy and laboratory tests. In relating to the changes of the health service, the cases of visiting health care and ambulatory medical service, and the total number of health education participants were greatly increased after the unification. The number of cases undergoing the vaccination and cervical cancer screening was similar to that of the pre-unification while the patient number of the registration to hypertension or diabetes showed a tendency to increase a little. Since the unification of the health subcenters, the frequency of laboratory tests has been increased, but the quality of health service has not been improved yet. Nevertheless, the unification seems to be positive according to the result of the great improvement in visiting health care, ambulatory medical service and health education service. The problems of the unification of the health subcenters were indicated in indefiniteness of the service details between the workers; excessively large building hard to be effectively managed; insufficient medical instruments, inappropriation of working expenses, lack of professional training for the health education, etc. Conclusions: For further active functions of the unified health subcenters, the minimal allocation basis to appoint doctors, nurses and administrative workers to do the duty should be differentiated from the basis for a health subcenter, and the fundamental instruments needs to be expanded to improve the quality of the medical service and visiting health care service. Moreover, the unified health subcenter needs to have definite service details between the workers, and should improve the working efficiency through the development of service-related guidelines.

Purpose: Adult Korean men belonging to the main economically active population are known to have long sedentary hours. This study was undertaken to determine the difference and relevance of sedentary hours on the nutrition, diet, and health status of adult men, and to suggest how to prevent health risk factors. Methods: Subjects (n = 1,068) were classified into 4 groups based on their sedentary hours, ranging from the first quartile (Q1) having the least hours spent sitting, to the fourth quartile (Q4) spending the longest hours. Results: Subjects belonging to Q4 had the lowest average age, the largest waist circumference, and the highest level of education. Among those engaged in economic activities, the ratio of white-collar workers was significantly higher in Q4. Accordingly, the rate of not doing high-intensity or moderate-intensity physical activity while working was also the highest in Q4. A significant difference was obtained in the drinking frequency between groups, but this was found to be associated with the average working hours rather than sedentary hours. The proportion of not doing aerobic exercise was higher with longer sitting hours. The highest diagnosis of diabetes (8.8%) was obtained in the Q4 group. Among the factors related to cardiovascular disease, only low density lipoprotein-cholesterol showed a significant difference, with Q4 being significantly higher than Q1. Considering energy and nutrient intake, vitamin B₁ and calcium intake were the lowest in the group with the longest sitting hours, as well as the least consumption of vitamin C than the recommended estimated average requirement. Conclusion: The results of this study suggest that the health and nutritional status of Korean adult men are affected by sedentary hours. This should be recognized as a health risk factor and guidelines need to be developed for sedentary lifestyle management.

This study examined the relationship among plasma homocysteine, folate, and vitamin $B_{12}$ levels and neurocognitive function in 118 community-dwelling elderly subjects (mean age, $75.1{\pm}6.7$ years). The Mini-Mental State Examination (MMSE-KC) was used to screen and assess neurocognitive function in the participants. Dietary intake data including the use of dietary supplements were obtained using the 24-hour recall method by well-trained interviewers. Plasma folate and vitamin $B_{12}$ concentrations were analyzed by radioimmunoassay, and homocysteine was assessed by a high performance liquid chromatography-fluorescence method. The proportions of participants with suboptimal levels of plasma folate (< 3 ng/mL), vitamin $B_{12}$ (< 221 pmol/mL), and homocysteine (> $15{\mu}mol/L$) were 16.1%, 5.9%, and 21.2%, respectively. A multiple regression analysis showed that plasma homocysteine was negatively associated with plasma folate and vitamin $B_{12}$ levels. The MMSE-KC test scores were significantly associated with plasma homocysteine and folate, but not with vitamin $B_{12}$, after adjusting for age, gender, body mass index, living with spouse, education, current smoking, energy intake, and chronic diseases such as hypertension, diabetes, thyroid disease, dyslipidemia, stroke, and cardiovascular disease. A general linear model adjusted for covariates revealed that MMSE-KC test scores increased from the lowest to the highest quartiles of vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, vitamin $B_{12}$, and vitamin C intake (p for trend = 0.012, 0.039, 0.014, 0.046, 0.026, respectively). These results indicate that the problem of folate inadequacy and hyperhomocysteinemia are highly prevalent among community-dwelling elderly people and that dietary intake of the B vitamins and vitamin C is positively associated with cognitive function scores.

This study aims to identify geographical variations and factors that affect smoking rates. The data are collected from the Community Health Survey conducted between 2009 and 2011 by Korea Centers for Disease Control and Prevention and other government organizations. Correlation and multiple regression analysis were used to examine the factors influencing smoking rates. For the purpose of investigating regional variations, we employed a decision tree model. The study has found that the significant factors associated with geographical variations in the smoking rates were the rate of hazardous drinking, the completion rate of hypertension education, the experience rate of anti-smoking campaigns, stress awareness rate, hypertension prevalence, health insurance cost, diabetes prevalence, obesity rate, and strength training rate. Convergence-based analysis on geographical variations of the smoking rates is highly important when the regionally customized healthcare programs is implemented. In the future, it is necessary to develop effective program and customized approach for the regions of high smoking rates. Our study is expected to be used as meaningful data for the design of effective health care programs and assessments to lead effective non-smoking program.

The purpose of this study was to investigate the blood concentrations of lipids, insulin and ascorbic acid, and their correlations in obese college men in Gyeongnam area. The blood pressure was significantly higher (p<0.001) in the obese group($127.8{\pm}7.2/86.7{\pm}9.2\;mmHg$) than the control group($112.8{\pm}6.6/71.9{\pm}6.6\;mmHg$). The serum triglyceride (p<0.01), total cholesterol (p<0.01), LDL-cholesterol (p<0.05), insulin (p<0.001) concentrations and atherogenic index (AI) (p<0.001) were significantly higher in the obese group ($158.8{\pm}79.7\;{\mu}U/L$, $185.0{\pm}26.8\;{\mu}U/L$, $111.9{\pm}28.1\;{\mu}U/L$, $15.2{\pm}5.6\;{\mu}U/L$, $3.6{\pm}1.0$) than the control group($111.9{\pm}35.8\;{\mu}U/L$, $165.9{\pm}19.4\;{\mu}U/L$, $97.0{\pm}16.4\;{\mu}U/L$, $8.9{\pm}4.4\;{\mu}U/L$, $2.6{\pm}0.3$), but HDL-cholesterol concentration was significantly higher (p<0.01) in the control group($46.5{\pm}7.2\;{\mu}U/L$) than the obese group($41.3{\pm}6.9\;{\mu}U/L$). On the other hand, there was no significant difference in the plasma ascorbic acid concentration in both groups. The ascorbic acid concentration was negatively correlated with total cholesterol level in the control group, and with triglyceride, total cholesterol levels and diastolic blood pressure in the obese group (p<0.05). These data show that young adult obesity might be related to hyperlipidemia, atherosclerosis, hypertension and diabetes mellitus, and that the nutrition of ascorbic acid is more important for obese males than normal weight males.

Periodontal diseases occur from the interplay between increased bacterial response and the response of the host immune system over time. Anxiety and depression can impair immunological defense mechanisms, causing accumulation of periodontopathogens and thus exacerbating periodontal disease. We investigated the relationship of anxiety and depression to periodontal diseases in Korean women. In this study, 3,551 women aged ${\geq}19$ years were evaluated based on data from the first year (2010) of the Fifth Korea National Health and Nutrition Examination Survey. The analysis of the factors that caused periodontal diseases revealed that dental floss or interdental toothbrush nonuse behaviors have been shown to increase the risk of periodontal disease (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.14~1.95). After adjusting for conditions such as age, marital status, income, educational level, economic activity, diabetes mellitus, smoking, drinking, and frequencies of toothbrushing and interdental cleaning, we found that anxiety and depression increased the risk of developing periodontal diseases (OR, 1.47; 95% CI, 1.04~2.09). People with anxiety and depression have a higher prevalence of periodontal diseases than people without anxiety and depression. Thus, periodic periodontal care and effective self-care education are needed to manage periodontal diseases.

This study was carried out to idenify the health problems and needs of crippled persons in order to develop a community based rehabilitation service program through public health center. Information on health problems and needs were obtained from 120 crippled persons staying at home by questionaire and a measuring ADL. The results were summarized as follows 1. Among 120 subjects, male crippled (70.3%) outnumbered female crippled (29.7%). Many crippled persons belonged to the 40-49 age group (33.6%) while others were over 60 years (17.4%). There were 36.8% crippled persons with an elementary education, 26.5% had completed high school, 14.5% had completed middle school. 31% of the crippled persons were employed but most of them had unskilled jobs. 80% of the respondents replied that their monthly income was under 800,000 won. 2. The major causes of their handicap were due to acquired factors(92%) such as accidents, in fectious & communicable diseases and chronic diseases rather than congenital factors(8%). Crippled persons who belong to the first grade of disabilities were 14.8%, the second grade 35.7%, the third grade 21.7%, the forth grade 12.2%, the fifth grade 12.2% and the sixth grade 3.5%. 3. This study measured the degree of the ADL of crippled persons by a modified Barthel Index including 11 items. 73.5% of them were fully independent, 8.5% required minimal help, 2.7% required moderate help, 6.0% required substantial help and 9.4% were unable to perform task. In response to the 11 items of ADL, crippled persons required more help in stair climbing, ambulation and bathing than in other items. 4. In responding to concerning health problems, 10.3% of the subjects replied with incontinence, 8.5% malnutrition, 7.6% fecal incontinence and bedsores 2.6%. Chronic diseases which needs treatment were chronic pain(61.0 %), hypertension(16.5%) and diabetes(16.5%) 5. To the question of what type of rehabilitation services subjects required, chronic diseases management(52.1%) and physical therapy (41.2%) were the highest. The most important social welfare services subjects required were economics support (51.3%) and introductions to job opportunities(42%).
