The objective of this study was to investigate the effects of dietary vitamin B intake on biomarkers related to lipid metabolism, inflammation and blood glucose control, that are important in the development of type 2 diabetes and its complications. Seventy-six adults (42 males, 34 females) were recruited from a group of diabetes patients who had visited the medical center for treatment. Data on anthropometric characteristics and dietary intake of thiamine, riboflavin, niacin, vitamin B₆ and folate were collected using 24-hour diet recall and the CAN Pro 4.0 program. Also, data on clinical indices such as serum lipids, blood pressure, high-sensitivity C-reactive protein (hs-CRP), hemoglobin A1c (HbA1c) and homeostasis model assessment 2-insulin resistance (HOMA2-IR) were collected and analyzed for correlation with dietary vitamin B intake. Results from the dietary intake survey showed that riboflavin and folate intake (in males) and folate intake (in females) were below the Dietary Reference Intake for Koreans. Statistical analysis revealed a negative correlation between hs-CRP and dietary intake of B vitamins. Riboflavin intake was inversely associated with systolic blood pressure after adjustments for age, BMI, smoking, alcohol consumption, exercise, ingestion of diabetes mellitus medication and energy intake (p<0.05). Our results suggest that dietary vitamin B may influence inflammation and consequently may help in better management of type 2 diabetes.

Uncoupling protein-1 (UCP-1) plays a major role in thermogenesis, and has been implicated in the pathogenesis of obesity and metabolic disorders. The aim of this study was to estimate the effects of A-3826G polymorphism of UCP-1 gene on body fat distribution. Two hundred forty eight Korean female overweight subjects with BMI more than 25 kgfm2 participated in this study. The areas of abdominal subcutaneous and visceral fat of all subjects were measured from computed tomography cross sectional pictures of the umbilical region. Subcutaneous fat areas of upper and lower thigh were also measured. Body composition was measured by bio-impedance analysis, and serum concentrations of biochemical parameters, such as glucose, triglyceride, cholesterol etc, were also measured. Genotype of UCP-1 was analyzed by polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP) method. The frequencies of UCP-1 genotypes were AA type; $27.8\%,\;AG\;type;\;51.2\%\;and\;GG\;type;\;21.0\%,$ and the frequency of G allele was 0.47. Body weight, BMI, WHR, SBP, DBP and body compositions were not significantly different by UCP-1 genotype. Abdominal visceral fat area was significantly higher in AG and GG type compared with AA type (p=0.009), but subcutaneous fat areas were not significantly different by UCP-1 genotype. Among biochemical parameters, LDL cholesterol level was significantly higher in GG type compared with AA and AG types (p=0.033). Among all subjects, 121 subjects finished 1 month weight loss program containing hypocaloric diet and exercise. The reduction of body weight and BMI were lower in GG type compared with AA/AG type even though statistical significances were not found (p > 0.05). These results suggest that UCP-1 genotype has a significant effect on visceral fat accumulation among Korean female overweight subjects with BMI more than $25\;kg/m^2$.

The purpose of this study was to investigate the difference in nutrient intake according to the level of self-perception of health status, aging status and life satisfaction of the rural elderly. The factors for the study were surveyed by interview method. The subjects were 270 people(71 male, 129 female) aged over 65 years(73.5 $\pm$ 5.6ys) in the Ham-an area. The obtained results as follows : By evaluation of self-perception of health status, 57.5% of subjects answered they are in a bad health condition. The 91.5% of subjects had diseases(rheumatitis & arthritis 31.4%, cardiovascular disease 20.2%, gastric disease 10.2%). The women had more diseases than the men(p < 0.01). The subjects took medical treatment in private hospital(40.5%) and public health centers(35.0%). The men showed better level of aging status(p < 0.001) and life satisfaction index(p < 0.01) than the worsen. Living with spouse influenced the aging status(p < 0.05) and the more pocket money influenced life satisfaction(p < 0.05) and aging status(p < 0.05). The elderly who eat regularly 3 times a day(p < 0.05) and have a good appetite(p < 0.001) appeared to have positive effect on the self perception of health status and aging status. An increasing level of the self-perception of health status and regular exercise worked to improve aging status(p < 0.001). The habits of smoking and alcohol drinking, however had no effect on any index. The self-perception of health status affected the nutrient intake, but only in female elderly. The aging status and the life satisfaction index related overall positively to the intake of nutrients. In conclusion, the study shows that gender did influence nutrient intake in the elderly. The women who live alone rated lowest in social resources and health condition therefore their nutrient intake was also extremely in deficit. For successful aging, a program for rural elderly is needed, i.e. actions to provide minimum economic life, food delivery and psychological/physical health care through regional public health centers.

Objectives: This study was conducted to identify the rates of perceived stress of elderly people over 65 years old and to confirm the influence of stress on general health and oral health status. Methods: Using data from the National Health and Nutrition Survey for 2014, 1,472 people over 65 years of age were selected as final subjects. Stress was used as an independent variable and dependent variables were included physical health (perceived health status), mental health (depression), and oral health (perceived oral health status). The following confounding variables were adjusted for the current study: demographic characteristics (gender, age, education level, house income) and health - related characteristics (drinking, smoking, exercise, frequency of tooth brushing, using oral care product, dental exam, comorbidity, restrict activity). Complex sampling analysis was applied and logistic regression was performed to determine the effects of stress on physical health, mental health and oral health status. Odds ratio (OR) and 95% confidence interval (95% Confidence Interval, 95% CI) were calculated. Results: Logistic regression indicated that stress was significantly associated with low physical health (OR=2.18, 95%CI: 1.49-3.20), low mental health (OR=8.68, 95%CI: 4.98-15.11), low oral health (OR=1.53, 95%CI: 1.06-2.21) after adjusting for confounding variables. Conclusions: The perceived stress of the elderly was found to be related to the general health and oral health status. Therefore, it is necessary to evaluate stress as a predictor of health risk for the health promotion of the elderly on multidisciplinary assessment and continuous evaluation. In addition, health support policies should be provided to achieve good health status for elderly.

This study reports on the development of a dietary education program for Korean young adults in single-person households. The 7th National Health and Nutrition Survey (2016-2018) was used to compare and analyze the dietary behavior of single-person households and multi-person households, and an online survey was conducted on 350 young adults (age 19-39 years) living in Seoul. According to the analysis, single-person households had higher rates of breakfast and eating out than multi-person households, and significantly lower average intake of energy and nutrients (p<0.05). In particular, in the case of single-person households, the lower the frequency of cooking at home, the higher the rate of breakfast and the higher the frequency of eating out and delivery food (p<0.05). Based on the survey, a dietary education program for young adults single-person households was developed by applying the DESIGN six-step procedure and social cognitive theory as a conceptual model. The first session consisted of the health and economic benefits of home-cooked meals, the second session of the importance of the breakfast and the effect of exercise in life, the third session of the importance of balanced nutrition and the principles of a healthy diet, the fourth session of food safety and storage, and the fifth session of social dining. Each session was composed of a combination of theoretical lectures to motivate 'more making and eating healthy home-cooked meals' and cooking practice for improving behavioral performance.

The aim of this study was to analyze dieting practices and tendencies in 2016 using big data. The keywords related to diet were collected from the portal site Naver and analyzed through simple frequency, N-gram, keyword network, and analysis of seasonality. The results showed that exercise had the highest frequency in simple frequency analysis. However, diet menu appeared most frequently in N-gram analysis. In addition, analysis of seasonality showed that the interest of subjects in diet increased steadily from February to July and peaked in October 2016. The monthly frequency of the keyword highfat diet was highest in October, because that showed the 'Low Carbohydrate High Fat' TV program. Although diet showed a certain pattern on a yearly basis, the emergence of new trendy diets in mass media also affects the pattern of diet. Therefore, it is considered that continuous monitoring and analysis of diet is needed rather than periodic monitoring.

The purpose of this study was to investigate the effects of physical activity in the elderly with osteoarthritis on stress and health-related quality of life (EQ-5D). This study performed data analysis using the SPSS 17.0 program in 104 elderly people with osteoarthritis over 65 years old using raw data from the 7th National Health and Nutrition Survey. The main results of this study are as follows: Males exercised more strength than women, and the better the subjective health status, the higher the rate of walking and aerobic activity. The group that felt stress showed a higher rate of walking and aerobic activity than the group that had no stress, and one group that felt a little stress practiced walking more than 3 days. The exercise ability of the elderly with osteoarthritis was better in the group who practiced walking, strength training, and aerobic activity than in the group without physical activity, and in self-management, the group practicing exercise and aerobic activity had problems with self-management. There was no daily activity, and the group that practiced walking and strength training also showed a high level of daily activity. In the area of pain/discomfort, the group practicing walking showed less pain/discomfort, and in the area of anxiety/depression, the group practicing walking showed less anxiety/depression. In conclusion, it is considered that in order to increase the quality of life of the elderly with osteoarthritis and to manage the stress, active efforts to increase the level of physical activity are necessary.

Purpose: The purpose of this study was to analyze the relationship among life style, body composition and Bone Mineral Density (BMD) in community dwelling Korean adults. Methods: Data were collected from 140 adults who participated in a health check-up program at community health departments in D city, Choong-chung providence. Subjects' life style was assessed with a structured interview survey. Body composition analyses were performed by the bioimpedence method and BMD was measured by peripheral dual energy X-ray absorptionmetry. Results: Among the subjects, 39.3% showed normal BMD values, 50.7% were osteopenic and 10% were assessed as osteoporotic. BMD was significantly different by gender, age, education, economic status and BMI. Subjects who had three or more meals/day had higher BMD then who had less than three meals (t=-2.273, p=.026). BMD was not influenced by regular exercise, alcohol consumption, or smoking. In terms of body composition, there was a significant relationship between fat free mass and BMD (r=.172, p=.043). Conclusion: Implementing an osteoporosis prevention program would be warrented considering the significant proportion of osteopenic or osteoporotic subjects. Regular eating habit with three meals for adequate nutrition need to be emphasized to prevent further bone loss in this population. Among the body composition, fat free mass seem to be the mostly predicting factor for BMD.

The study examined the difference of the physique, the physical strength, and the physical constitution between meal and non-meal service schools at the countryside, and concluded as follows: 1) The effects on the physical development Meal service school student's height was 0.41~2.38cm taller, weight 0.21~1.58kg heavier, and the chests 0.15~2.55cm bigger than the non-meal service school students. Therefore, the effects of the school meal service on the student's physique development proved positive. 2) The effects on the physical strength Today, the student's physical growth is reinforced by consuming high calorie food, while their physical exercise is decreased. As a result, obesity becomes another problem. In this respect, physical strength is a significant factor in judging the physical condition of the students. This study compared the meal service schools with the non-meal service schools by suing six items of the physical strength test those schools. In comparison, the meal service school students were better than the others in most items except in the eleven year old girl's 100 meter running and the ball throwing, and the ten year old boy's 600meter running. It means that school meal service affects the physical growth in a positive manner. 3) The effects on the physical constitution The students in their growing period should have their meals not only balanced, but regularly since this helps to maintain their health. Insufficient nutrition may disturb the balanced physical growth of cause a weak or powerless physical constitution. As shown at the table 6, meal service school students who had a balanced meal have 0.01% lower incidence of disease. and 3.11~7.32% less myophia than the other. The average 0.39 to 0.63 cavity of the meal service school students also show that their constitutions are better than the non-meal service ones. In conclusion, the school meal service program gives every student a regular nutritious meal which results in a balanced physical growth. Erentually, the healthier students could be the healthier social menbers which promise a brighter society in the future.
