Purpose: The aim of this study was to investigate the dietary quality of food consumed away from home among Korean children and adolescents. Methods: Data were obtained from the 2010~2012 KNHANES (Korea National Health and Nutrition Examination Survey) and included 3,583 subjects aged 7 to 18 years old. The frequency of food consumed away from home was dichotomized into more than once or less than once per day. Results: Thirty percent of subjects were shown to consume food away from home more than once per day, and older children from higher income households showed a higher frequency of food consumed away from home compared to other children. The percentage of children and adolescents cited as regularly skipping breakfast was 19%. Individuals who ate out more than once per day showed higher consumption of energy and sodium than those who ate out less than once per day. Conclusion: Excessive intakes of energy and sodium are associated with obesity, high blood pressure, diabetes, and obesity-related diseases. Thus, there is a need for nutritional intervention and educational efforts to improve child nutrition and prevent obesity.

Objectives : This study aimed to investigate relationship between the psychological factors, the prevalence, and perception of temporomandibular disorder in Korean adults. Methods : A total of 7203 data were derived from Korean national health and nutritional examination survey. All data were analyzed using R-COMMANDER(12.2 SDI) program. Results : The prevalence of temporomandibular disorder in Korean adults was 3.1% and 10.5% of adults with temporomandibular disorder (TMD) had more than one TMD related symptom. Women had higher prevalence rate of TMD related symptom than men. Prevalence rate in TMD was low in the younger age, the higher education level, higher income, and the professionals. Psychological factors including cognition of stress and depression was shown to be closely related with suicidal ideation and TMD prevalence. Conclusions : To prevent TMD, it is necessary to provide the systematic oral health education and to develop the combined psychological counseling with treatment program.

Purpose: Visual impairment, hearing impairment, and masticatory discomfort each influence quality of life (QoL). However, little is known regarding the impact of their coexistence on QoL. Therefore, we aimed to investigate the influence of the coexistence of visual impairment, hearing impairment, and masticatory discomfort on QoL among middle-aged adults aged 40-64. Methods: This study involved a secondary data analysis utilizing the data from years 1 and 2 of the eighth Korea National Health and Nutrition Examination Survey. To evaluate the influence of the coexistence of visual impairment, hearing impairment, and masticatory discomfort on QoL, we conducted a complex sample hierarchical multiple regression analysis. Results: When visual impairment, hearing impairment, and masticatory discomfort coexisted, the QoL was significantly lower than in individuals without any of these conditions. Conclusion: The coexistence of visual impairment, hearing impairment, and masticatory discomfort was negatively correlated with QoL. Therefore, it is important to prepare for old age through appropriate health management during middle age.

Purpose: This study was conducted to determine the impact of premature menopause (PM) on metabolic syndrome and its components to determine its contribution to the health of Korean women undergoing natural menopause. Methods: This study used data from the 4^th to 8^th National Health and Nutrition Examination Survey (2007~2021). A total of 11,989 women aged 30 to 65 who responded to questions about their current menstrual status, natural menopause status and its age. Complex sample multivariate Cox proportional hazards regression analysis was used. Results: Compared with women with late menopause, women with PM had a 1.34 times higher risk of developing metabolic syndrome. Excluding the risk of high blood pressure, women with PM had a significantly higher risks of increased waist circumference, decreased high-density lipoprotein, increased risk of high triglycerides, and increased fasting blood glucose. Conclusions: The results of this study provided data that can be applied to policies or interventions to prevent or manage metabolic syndrome in women with PM in Korea.

This study analyzed the health characteristics and comorbidity of adult men aged 40 years by dividing them into a control group of those without any disease related to fine dust and a patient group with one or more diseases related to fine dust in areas with high levels of fine dust pollution using the sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017). Among the general characteristics, the mean age of the patient group was significantly older than that of the control group (p<0.001), and in terms of the health-related characteristics, the frequency of breakfast consumption in the patient group was higher than in the control group (p<0.043). The body measurements were similar in the patient and control groups. Regarding the prevalence of comorbidity, the patient group showed a higher prevalence of hypertension, dyslipidemia, stroke, myocardial infarction, heart failure, and diabetes than the control group, but the differences were not statistically significant. On the other hand, the prevalence of other cancers (except stomach cancer, liver cancer, colorectal cancer, breast cancer, and cervical cancer) in the patient group was higher than in the control group (p<0.05). In terms of the clinical characteristics, the glycated hemoglobin levels in the patient group were significantly higher than in the control group (p<0.048). Information on nutrition and health in areas with frequent occurrences of fine dust was obtained through the study results, which can be used as basic data for measures of health and diet management against diseases that will increase in relation to fine dust.

Objectives: This study was conducted to estimate medical expenditure attributable to overweight and obesity in adults with hypertension, diabetes and dyslipidemia using Korea National Health and Nutrition Examination survey data and Korea National Health Corporation data. Methods: The medical expenditure of hypertension, diabetes and dyslipidemia related to overweight and obesity were composed of inpatient care costs, outpatient care costs and medication costs. The population attributable risk (PAR) of overweight and obesity was calculated from national representative data of Korea such as the National Health Insurance Corporation cohort data and 2005 Korea National Health and Nutrition Examination survey data. Results: The medical expenditure attributable to overweight and obesity of hypertension were 456 billion won (men : 215 billion won, women : 241 billion won). Those of diabetes were 282 billion won (men : 148 billion won, women : 135 billion won), and of dyslipidemia were 17 billion won (men : 9 billion won, women : 8 billion won). Consequently, these costs corresponded to 33.3% of total medical expenditure due to hypertension, diabetes and dyslipidemia. Conclusions: We found a substantial medical expenditure due to overweight and obesity of hypertension, diabetes and dyslipidemia were very high. In order to reduce these costs, effective national strategies for prevention and management of overweight and obesity should be established and implemented.

Purpose. This cross-sectional survey was conducted to described the compliance of Breast Self-Examination of middle-aged women using a convenient sample, and to examine relationships between the compliance of BSE and Health Beliefs, and the influencing factors on the compliance of BSE. Methods. The subjects were 373 literate volunteers who were from 41 to 60 years of age who visited 6 public health centers. From June 7, 2004 to August 20, 2004, data were collected by 5 research assistants using a self-report questionnaire. The questionnaire was used to obtain information on the general characteristics, knowledge, health beliefs, and compliance of BSE. Results. The findings of this study suggested that there were significant differences in the scores of the perceived susceptibility and severity between compliers and non-compliers of the BSE. BSE compliance was significantly correlated with knowledge, perceived susceptibility, and perceived severity. The most powerful predictor of BSE compliance was the perceived susceptibility. The perceived susceptibility, the perceived severity, the knowledge and educational level accounted for $41.8\%$ of the variance in middle aged women's BSE compliance. Conclusion. Increase in knowledge about breast cancer, with a concomitant increase in both perceived susceptibility and perceived severity could produce a subtle cue or motivating force sufficient to affect a behavior change. Further research is needed to examine the qualitative difference between BSE and other early detection behaviors.

The association between heavy metals in the blood and obesity has been examined in many studies. However, inconsistencies have been observed in the results from these studies. The present study was conducted using data from 119,181 participants of the Korea National Health and Nutrition Examination Survey (KNHANES) for 11 years in 2005 and between 2008 and 2017. The subjects with missing heavy metal blood tests, health interview data, and health examination data were excluded from the study. The study population comprised 1,844 individuals (972 men, 872 women) who were eligible for inclusion. It was found that obesity and abdominal obesity were associated with an increase in both blood mercury (P<0.001) and alanine aminotransferase (ALT) (P<0.001). After adjusting the confounding factors, those with concurrent high levels of ALT and the highest tertile of mercury showed an increased risk of obesity (odds ratio 4.46, 95%, confidence interval 2.23~8.90, P<0.001) as well as abdominal obesity (odds ratio 5.36, 95%, confidence interval 2.57~11.17, P<0.001). The interrelationship of mercury and ALT with the parameters of body mass index (P for interaction=0.009) and waist circumference (P for interaction=0.012), respectively, have been observed to be significant, suggesting that the reciprocal relationship could contribute to obesity and abdominal obesity.

The improvement of safety and health education method in construction site was investigated through the survey for workers and delphi technique. The results of preliminary survey done for workers were analyzed using the multi variance analyses, and the questionnaires for delphi survey were composed based on the results of preliminary survey. Finally, the participatory safety and health education method was suggested. The result showed that most of workers were very interested in accident prevention and health. On the contrary, they did not actively participate in safety activities in sites including safety and health education. In order to improve workers' levels of safety consciousness and prevent the construction accident, the participatory safety and health education method that construction workers directly examine and give presentations about accident causes and measures was suggested and verified by tests. One-way instructor-led safety and health education used widely and participatory safety and health education with workers were carried out by dividing participants into two groups. After education, the examination is done for two groups. The test results found that the average score of safety consciousness of the worker group that received participatory safety education was higher than that of the work group that received instructor-led safety education. And the Delphi technique utilizing experts was analyzed that participatory safety education has a great effect on improvement of workers' level of safety consciousness.

Objectives: The purpose of this study is to investigate the effect of health behavior on oral health of Korean adolescents. Methods: The study subjects were 1,071 adolescents of 13-18 years old from Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. Male students were 54.5% and female students were 45.5%. The study consisted of two groups: 13-15 years old and 16-18 years old groups. Data were analyzed by SAS 9.13 version. Results: Those who ingested alcohol had gingival bleeding in 41.0% and 31.0% in those who did not. Those who did not have regular oral examinations had 38.5% of gingival bleeding while those with regular oral examination had 29.7% of gingival bleeding (p<0.01). Students between 16 to 18 years old without oral care products tended to have more gingival bleeding than those who use auxiliary oral hygiene devices (OR=2.658, 95% CI=1.327-5.324). Conclusions: The oral health management of adolescents is closely related to health behavior. Cessation of alcohol ingestion and smoking is very important to improve the adolescent oral health.
