The purpose of this study was to find out the general problems of school food service and to explore a way to improve it, by examining elementary school teacher's consciousness and attitude toward it that gave a big impact on children's development of food habit. For attaining the purpose, the following research questions were posed : 1) What's elementary school teacher attitude toward school food service management? 2) What's elementary school teacher attitude toward school food service effect on children? 3) What's elementary school teacher opinion about how to develop school food service? The subjects of study were 328 male or female teachers who served at elementary school in urban and rural area, including eup, myon, or farming and fishing villages, Kyonggi province. A questionnaire survey was conducted over them. The conclusions were as follows: 1) Teacher Attitude Toward School Food Service Management Concerning food service place, the subjects were more satisfied at food service room(73.3%) than at classroom(23.0%). They responded that food service room was more effective, than classroom, for food transportation, distribution and post-arrangement. Their satisfaction at food service place was significantly different. The older teachers considered personnel management and cooking room's sanitary management to be more efficient, and their age made a significant difference to their consciousness of these things. Many teachers(63.1%) thought the measures to prevent and manage group food poisoning were relatively efficient. The male teachers expressed more affirmative view on the efficiency of school food expense management and menu preparation than female teachers, and there was a significant disparity between male and female teachers. 2) Elementary School Food Service Effect School food service was thought to be very effective for physical growth(74.1%) and physical strength improvement(70.1%). Teachers at smaller school revealed more affirmative response toward school food service effect on correcting an unbalanced diet, and older teachers considered its effect on nutrition knowledge acquisition and learning outcome to be more great. Teachers at larger school put less value on its effect on table manners, and school size produced a significant difference. The number of teachers who thought school food service generally raised parent concern and support for school(36.6%) was a little more than that of teachers who didn't think so(15.2%). And the number of teachers who didn't consider its effect on improving parent food life to be good(29.3%) was slightly more than that of teachers who did. 3) School Food Service Reform Measure What's most urgently needed for better school food service management appeared to be an expansion of facilities concerned, followed by more effective food distribution and transport, cooking room's better sanitary management, more successful food poisoning prevention and management, more effective food expense management, and an increase of food service personnel in the order named. The most effective means of school food service education was found to be a creation of link system to family, followed by a development of school food service education program, a development of teaching materials, an insertion of school food service in curriculum, and teacher education in the order named.

This study was conducted to analyze the relationship between the practice of aerobic exercise and the prevalence and risk of arthritis with comorbid chronic diseases. For this study, the National Health and Nutrition Examination Survey 2017-2019 data were used and 17,356 people were selected as subjects. The relationship between the practice of aerobic exercise and the prevalence and risk of arthritis according to demographic characteristics and chronic diseases was analyzed by the chi-square independence test and Breslow-Day test. While the rate of aerobic exercise was low among women, the elderly, the low-income group, the low-education group, and people living in rural areas, the prevalence and risk of arthritis were relatively high. And in the chronic disease-positive group, those who practiced aerobic exercise had a relatively lower prevalence and risk of arthritis than those who did not. In particular, the practice of aerobic exercise was an effective complement in reducing the prevalence and risk of arthritis in people with high blood pressure, diabetes, and dyslipidemia. Therefore, the practice of aerobic exercise such as walking, slow running, and aerobic dance should be recommended in terms of the preventive medicine and health care to people who are in the group with a high prevalence of arthritis in demographic characteristics and people who have comorbid chronic diseases.

Purpose: This study was performed to identify the relations between glaucoma and dietary patterns in Korean adults, aged 30 years or older. Methods: 6,453 subjects (male 2,759, female 3,694 subjects) who aged 30 years or older from the Korea National Health and Nutrition Examination Survey were included. Glaucoma was assessed based on the subjects were diagnosed by a doctor. At first, waist circumference and body mass index (BMI) were compared to investigate the association between glaucoma and obesity index. Secondly, dietary patterns using factor analysis for external blue colored fish(mackerel), seaweed(seaweed, laver), bean(bean, soybean milk), vegetables(sprout, spin, carrot, cabbage, cucumber, pepper, tomato, pumpkin) and fruits(tangerine, apple, pear, strawberry, grape, peach) were obtained. Lastly, regression analysis was used for glaucoma and emerged dietary factors. Results: In glaucoma and normal group, waist circumference and BMI were $82.25{\pm}9.96cm$ and $23.27{\pm}2.84kg/m^2$, $75.79{\pm}13.79cm$ and $22.39{\pm}4.06kg/m^2$, respectively. There was statistically significant difference (p<0.05). Three dietary patterns were emerged from the factor analysis, and factor 1 was included sprout, spin, carrot, cabbage, seaweed, cucumber, mackerel, laver. The factor 1 of dietary pattern was inversely related to the prevalence of glaucoma (OR: 0.697, 95%CI: 0.496-0.980, p=0.038), and model adjusting for age and sex was showed the same trend (OR: 0.698, 95%CI: 0.497-0.982, p=0.039). Conclusions: This study was analysed first with glaucoma and dietary pattern in Korean, and vegetables, laver and mackerel significant associated to reduce the risk of glaucoma.

Objective : This study was done to investigate the correlation between general quality of life(QOL) and disease specific QOL of tinnitus patients. Methods : 2009 National health and nutrition survey(NHNS) data were employed for analyzing the mean estimates of total population and tinnitus sub-group patients, and predicting the regression equation of mapping between EQ-5D and disease severity. Baseline statistical analyses and normality tests were done by using Student t-test, Chi-square test, Shapiro-Wilk test and ladder test. Hierarchial regression analyses were performed using related variables and predicted the optimal regression equations. Statistical significance was achieved if the probability was less than 5%. Results : Firstly, the standardized prevalence of tinnitus patient in South Korea was 18.69% and over 90th age-group was relatively higher than other groups. Mean value of domestic QOL measured by EQ-5D was estimated as 0.9486 and QOL of tinnitus subgroup(0.9169) was lower than the non-tinnitus subgroup(0.9559), significantly. Stratified by age and sex, QOLs of all sub-groups with tinnitus were lower than without tinnitus sub-groups significantly. Regression equations from 2009 NHNS data were developed using hierarchial regression analysis which is as follows. $$Y_{EQ-5D}=0.9224-0.0079{\times}T1-0.0261{\times}T2-0.0951{\times}T3+\sum_{i=1}^{n}{\beta}_i{\times}X_i\\{\hspace{95}}(0.0106){\hspace{3}}(0.0037){\hspace{30}}(0.0072){\hspace{30}}(0.0038)$$ ($X_i$=Other explanatory variables except Tinnitus QOL1, 2, 3, ${\beta}$= Regression Coefficient of Model 4) Conclusion : We confirmed the correlation among THI and EQ-5D and HUI-III, and developed the inference for regression equation of EQ-5D.

This study was conducted to analyze with a focus on gender whether the prevalence of hyperuricemia varies depending on sitting time and high-risk drinking by occupational group. For this study, the Korea National Health and Nutrition Examination Survey data were used, and 16,366 people were selected. The chi-square independence test and logistic regression model were used as the analysis method. The prevalence and risk of hyperuricemia by sitting time were different in the 'agricultural, forestry and fishery skilled workers' only in men. On the other hand, the prevalence with high-risk drinking, both men and women showed differences in 'managers, experts and related workers' and 'office worker'. Also, only women have differences in 'service and sales workers', 'technicians, equipment, machine operation and assembly workers' and 'unemployed'. These results inform men have a higher prevalence and risk of hyperuricemia and suggest that health care policies and medical services are needed to prevent it by occupational group.

The effect of body composition such as lean mass and fat mass on bone mineral density (BMD) is complex and still controversial. In this study, we investigated the relationship between body composition and bone mineral density using nation-wide data from 2008 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES) in 2,139 men and 2,193 postmenopausal women aged 50 years or older. Subjects with history of medication for osteoporosis or with diseases or malignancy affecting bone metabolism were excluded. Data of anthropometric measurements and demographic characteristics were collected by trained examiner. Fasting blood sample was obtained for blood chemistry analysis. BMD of the lumbar spine, total femur, and femoral neck, and body composition such as total lean mass (TLM), total fat mass (TFM), truncal fat mass (TrFM) were measured using dual-energy X-ray absorptiometry (DXA). There were significant positive correlations between body composition indices such as lean mass and fat mass with BMD. In multiple regression analysis, TLM was positively associated with BMD after adjusting age, body mass index, monthly house income, education level, physical activity, daily calcium intake and vitamin D concentration in both men and postmenopausal women. BMD at lumbar spine and femur in lowest quartile of TLM was significantly lower than other quartiles after adjusting those confounding factors in both gender. TrFM was negatively associated with total femur BMD in male and femur neck BMD in postmenopausal women after adjusting confounding factors. In conclusion, TLM is very important factor in maintaining BMD in subjects aged 50 years or older in men and postmenopausal women.

This study recognizes it as a social problem that can be prevented by basic research on safety security design for the elderly, and aims to clearly analyze risk factors for injury. For this study, raw data from the 6th Korean National Health and Nutrition Survey were employed and analyzed. Their social characteristics were classified with standards including gender, education, EuroQoL(human locomotion, normal activity and pain uncomfortableness), the quality of life(PHQ-(1)(2)(4)), recognition on stress, activity restriction status and associated causes(bone fracture and joint injury). Their epidemiological traits were chronic diseases, 'diabetes and hip-joint pain', and health-behavioral traits were 'smoking, breakfast frequency and high-level physical activity status.' In conclusion, it can be found that damage risk of elderly rose in case of female, lower education, inconvenience or limitation, pain or discomfort in locomotion and daily activities, higher recognition of stress, lower interest in work, feeling of depression, despair, and weariness, restriction in activity caused by bone fracture and joint injury, having diabetes and hip-joint pain, smoking, low frequency in having breakfast and high-level physical activities. Based on this study, we envision that an effective solution for injury risk factors caused by the organic relation can be reached in the near future.

Cardiovascular disease is caused by different factors. These factors include innateness factors such as aging, biological factors such as high blood pressure, and environmental factors such as stress. This study examined the factors associated with cardiovascular disease and the ways to reduce its prevalence by analyzing the data within the Korean National Health and Nutrition Examination Reports from 2013 to 2017, and particularly the survey and examination data for people over 50 years old. The study population was divided into two groups: members of the first group consumed riboflavin and niacin at the recommended rate while those in the second group did not. Riboflavin intake was correlated with hypertension, hyperglycemia, and a low HDL-cholesterol level, whereas niacin intake was correlated with hypertension, hyperglycemia, waist size, and a low HDL-cholesterol level. The combination of niacin and riboflavin intakes was correlated with hypertension, hyperglycemia, waist size, and a low HDL-cholesterol level (P<0.05). The combined intake of the recommended levels of riboflavin and niacin reduced the average physiological factor abnormality rate to 80%. Taken together, the beneficial effects of riboflavin and niacin can reduce the prevalence of cardiovascular disease.

Metabolic syndrome and allergic rhinitis are two important chronic diseases that affect people all over the world. Metabolic syndrome very often induces other diseases and the prevalence of allergic rhinitis is currently increasing. Aging is known to affect the pathogenesis of various diseases such as metabolic syndrome and allergy. This study examined the effects of metabolic syndrome and the prevalence of allergic rhinitis depending on different age groups and several general characteristics. This study was conducted by using the data from the Korea National Health and Nutrition Examination Survey from the 4th, 5th, 6th, and 7th-1 (2007~2016). The data used for this study was obtained from 51,854 people. In all age groups, our studies have shown that people without metabolic syndrome have a higher prevalence of allergic rhinitis than those people with metabolic syndrome, and the younger age group had the higher prevalence of allergic rhinitis (P<0.05). Overall, the results of this study found a significant effect on the prevalence of allergic rhinitis in each category of age, general characteristics (physical activity, smoking and drinking) and the presence or absence of metabolic syndrome (P<0.05). The evidence found in this study will help to understand the correlation between metabolic syndrome and allergy, and specifically allergic rhinitis.

Purpose: This study calculated the prevalence of cataract in Korean and examined corrected eyesight with different types of opacification of crystalline lens. Methods: Using the data of the national health and nutrition examination survey (NHANES), population-based and cross-sectional research were designed in this study. After dividing total 4,977 persons into different groups by age, from 40 to 95 and by sex, the prevalence of cataract with different types of opacification was investigated. The average age of the total subjects was $58.28{\pm}12.07$, and the number of men and women were 2,142(43.0%) and 2,835(57.0%), repectively. Eyesight was calculated when it was less than 0.63. Results: Among total 4,977 subjects, 40.6% (men 17.5%, women 23.1%) had cataract. Different prevalence rates were found with different types of cataract; nuclear cataract (56.3%), cortical cataract (23.4%), mixed cataract (16.2%), anterior subcapsular(3.0%), and posterior subcapsular (1.1%) in order. There was no difference among men and women by the types. And those in their 40's showed a higher prevalence of cortical cataract than those in the other age groups. Most of subjects whose corrected eyesight is less than 0.63 had anterior subcapsular cataract. Conclusions: The type of cataract having the highest prevalence was nuclear opacity. Moreover, epidemiologic investigation and prevention policy with different type of lens opacity seems to be required.
