Dietary nitrate supplementation from green leafy vegetables and beetroot is involved in the 'nitrate-nitrite-nitric oxide (NO) pathway' and is reported to have important vascular impacts. This study evaluated the blood parameters and blood flow change subsequent to a raw juice diet program. The 28 subjects who voluntarily participated in the raw juice diet program at Sahmyook University were instructed to drink the juice composed of fruits and vegetables instead of partaking the usual meal, at a scheduled time daily. The study was approved by the research ethics council of the Sahmyook University (SYUIRB 2014-043). Evaluation of the participants after the required duration revealed decreased levels of soft lean mass (P<0.05), skeletal muscle mass (P<0.001), body fat mass (P<0.001), body mass index (P<0.001) and circulating levels of total cholesterol (P<0.001), triglycerides (P<0.05), HDL-cholesterol (P<0.01), LDL-cholesterol (P<0.01), and blood urea nitrogen (P<0.001). Conversely, circulating levels of creatinine (P<0.001), hemoglobin (P<0.001), and hematocrit (P<0.01) were increased after the intervention. The blood flow levels were also increased after the program (P<0.001). Our results indicate that a short-term raw juice diet contributes to the improvement of vascular blood flow and blood lipid parameters, and decreases the lean muscle mass related to dehydration.

The purpose of this study was to assess the nutritional status of Korean workers with occupational exposure to lead by estimating nutrients and flood intakes so that we can eventually establish the dietary guidelines to be recommended for the lead workers. Food consumption survey was conducted by a 24-hr recall method with 135 lead workers and 50 non-exposed controls. Food intake data were convened into nutrients intake using computer aided nutritional analysis program. Mean daily energy intake and percentage of recommended daily allowance (RDA) of male lead workers were 2138 local and 87% of RDA while those of control were estimated as 2234 kcal and 91% of RDA. Mean daily intakes of nutrients of male lead workers were 78 g (111% RDA) for protein 502 mg (71% RDA) for calcium, 11.7 mg (97% RDA) for iron, 665 $\mu$g R.E (95% RDA) for vitamin A, 1.39 mg (108% RDA) for thiamin, 1.14 mg (77% RDA) for riboflavin, 15 mg N.E (92% RDA) for niacin and 66 mg (94% RDA) for vitamin C. On average, male lead workers showed significantly lower protein, calcium, iron, sodium, potassium, niacin and vitamin C intakes than control group while cholesterol intake of the male lead workers was significantly higher than that of control group. Intakes of calcium of male lead workers were Less than 75% RDA meaning that nutritional intake of calcium of male lead workers was insufficient and could possibly result in nutritional deficient. Some food groups such as milk, meat and fish must be strongly suggested to improve nutritional status of lead workers. Continuing nutrition monitoring and appropriate nutrition intervention for lead workers most be conducted further.

This study aims to identify the dietary patterns relevant to obesity of Korean women among low income classes. Adults 20-64 years were used as study subjects from the data of 2005 Korea National Health and Nutrition Examination Survey. We compared obese and normal-weight women in terms of their nutrients intake, diet quality and food patterns. Diet quality was assessed by using the Nutritional Adequacy Ratio (NAR) and Index of Nutritional Quality (INQ). Our results showed higher prevalence of obesity among lower socioeconomic status women. In men, there were no significant associations with socioeconomic status and prevalence of obesity. Higher risk of nutritional inadequacy was observed among obese women compared to normal weight women. Obese women showed significantly lower INQ for nutrients such as Ca, Fe, Vitamin A, Thiamin, Riboflavin and Vitamin C compared to other women. They consumed significantly higher amount of rice (p < 0.05) and lower amount of vegetables (p < 0.01). By contrast, obese men from low income classes showed higher intake of those nutrients. Obese men also consumed significantly higher amount of meats than normal weight men. Therefore, this study suggests that gender-specific approaches based on economic situation should be considered in developing the intervention program for managing obesity for low income classes.

This study was undertaken to develop web-based nutrition information contents for the older adults. Twenty six domestic web-sites were analyzed and then 12 foreign web-sites and 4 education materials for the elderly of foreign university were benchmarked. Also a lot of literatures on elderly education program were reviewed. A card-sorting task was performed with 8 older adults to ascertain how the target audience organized information about nutrition. The results were as fellows. Among 26 domestic web-sites, 2 sites(7.7%) were only for the elderly. Main topics of information contents for the elderly included 'Importance of Healthy Eating', 'DRI', 'Dietary Guidelines'. Four of twelve foreign web-sites were for the elderly nutrition education. Topics of 'Dietary Guideline', 'Meal Program' were found in 4 sites and 'Importance of Healthy Eating', 'Diet & Disease', 'DRI, 'Food Guide Pyramid', 'Nutrition Fact Labels' were found in 3 sites. Education materials of foreign university dealt with basic information on 'nutrient needs changes related with aging', 'Heart & Bone Healthy Eating Plan', 'Food Guide Pyramid'. Also topics on 'Eating on a budget', 'Eating Out Guideline' were included for practical use for the elderly. Based on card-sorting process, contents framework for web-site was developed and 4 main menus for framework were respectively named as 'Nutrition', 'Meals', 'Foods'. 'Check up Nutritional Health' by panel discussion. Finally we developed nutrition information contents for 4 main menus. We focused on helping older adults recognize the importance of healthy eating and apply the nutrition information to practical use. We expect that the developed framework of contents can be a guideline for indentifying the information needs of older adults in developing effective nutrition intervention program. And we suggest that the survey for target people should be peformed for the web-site to be user-friendly designed and the developed contents be evaluated and revised in the near future.

It is important for young adults to establish good dietary behavior for healthy life. The prevalence of obesity in college students has increased gradually. The obesity is one of the most prevalent health problems in S. Korea. Moreover, obesity is closely related with the disease such as cardiovascular disease, diabetes mellitus. The purpose of this study was to evaluate health practice, serum components and nutrient intake of the college students according to Body Mass Index (BMI) level. 400 male and female freshmen students in 4 year university located near to Seoul metropolitan area were surveyed respectively through the health check-up procedure for college entrance in February. Survey was carried out for them by questionnaires, including a 24-hour dietary recall and anthropometric measurements. Blood samples were obtained while fasting. Nutrient intake was expressed by DDS(Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). Nutrition level was analyzed by Can-Pro (Korea Nutrition Association). And for the quantity intake, percentage ratio against daily requirement(by KDRIs) and MAR(Mean Adequacy Ratio) were calculated. Underweight group($BMI<18.5kg/m^2$), normal weight group($18.5) and overweight group($BMI<23.0 kg/m^2$) were 18.5%, 61.2% and 19.3% respectively. Nutrient intake levels and food intake status were not significantly different among three groups. The mean nutrient adequacy ratio (MAR) was not significantly different by BMI status. Nutrient intakes of calcium, iron, and riboflavin were especially low for all the students. Overweight group showed high blood pressure(120.9/79.3 mmHg) compared with the underweight group (116.4/ 75.8mmHg) but the difference was not significant. The serum triglyceride level in overweight group (94,0mg%) was higher than that in normal (70.9mg%) or underweight group(70.8mg%)(p<0.05). HDL-cholesterol level in overweight (43.8 mg%) group was not significantly different from that in underweight group (45.9mg%). BMI was positively correlated with blood pressure, hemoglobin, and the intake of total fat and cholesterol. But it was negatively correlated with HDL-cholesterol level. With these results overweight group is closely related with the cardiovascular disease risks, such as high blood pressure and high triglycerides and cholesterol. Thus, a health intervention program including weight control is required for young adults.

The aim of the study was to identify the effects of a social-support-based walking program for residents in rural areas. Data were collected from 120 residents who are residential in Chungcheongnam-do and participated in walking program at community health centers from March and September 2013. Collected data included body mass index, body fat mass, and skeletal muscle mass and physical Activity. The data were analyzed using a paired t-test with SPSS19.0. This study showed that a 7-month walking program had positive effects on the physical health index, representing reductions in the body mass index(t=-12.418, p<.001), body fat mass indes(t=13.031, p<.001) and an improvement in the skeletal muscle mass(t=-12.642, p<.001). Health behavior index; dietary practice guideline score(t= -4.324, p<.001), physical activity day(t=-8.715, p<.001), high risk drinking day(t=6.298, p<.001) were improved through walking program. These results indicated that the walking program for the community was effective in improving the health status of the participants. Therefore, I suggest that the development and running of various social-support-based walking program be required by applying the results.

The purpose of this study was to investigate the relationship between physical activity, diet and mental health of elderly and to use the study as basic data for a program development for elderly. This was a secondary data analysis study using the 2015 National Health and Nutrition Survey and the study subjects included 1,484 individuals aged 65 and over. The results showed that depression and stress perception in young-old were higher than old-old's and the suicidal ideation rate of old-old was higher than young-old's. In case of eating patterns, 'poor eating' in old-old was higher than young old's. Regression analysis showed that middle-intensity physical activity and eating patterns were associated with mental health of the elderly. Based on the results, it is necessary to develop a differentiated nursing intervention program suitable for the elderly by age.

This study was conducted to develop a 26-week obesity management program and examine the effects of this program on obesity index (body mass index, fat mass percentage, and triglyceride) and psychological variables, self-esteem, dietary self-efficacy, physical activity self-efficacy, and body image among 46 4th-6th obese elementary school children with a BMI above $20kg/m^2$ using a nonequivalent control group quasi-experimental design (experimental group=23, control group=23). This program included a 12-week intensive course (12 times for group education on obesity, exercise, and nutrition, 36 times for practicing diet and physical exercise, and 5 times for psychological counseling) and a 14-week follow-up course (3 times for group education, 3 times for checking diet and physical exercise, and 1 time for psychological counseling. The collected data were analyzed by the Kolmogorov-Smirnov test, chi-squared test, Fisher's exact probability, t-test, and ANCOVA. There were above normal values in body mass index ($20kg/m^2$), fat mass percentage (15-20%), and triglyceride tolerance ($90mg/d{\ell}$) in experimental group and control group. The body mass index (F=94.869, p<.001), fat mass percentage (F=37.361, p<.001), and triglyceride tolerance (F=7.907, p= .007) were significantly lower, while self-esteem (F=19.661, p<.001), dietary self-efficacy (F=16.942, p<.001), physical activity self-efficacy (F=9.363, p= .004), and body image (F=9.782, p= .003) were significantly higher in the experimental group than the control group after 26 weeks. This study provides evidence that the 26-weeks obesity management program is an effective nursing intervention for managing obesity and psychological variables of obese elementary school children.

Benign prostatic hyperplasia (BPH) is one the most common prostate diseases in middle aged and elderly men. This study was conducted to investigate diet and lifestyle risk factors for benign prostatic hyperplasia in a community-dwelling free-living population group. The dietary data were collected from the 601 male subjects aged 50-79 years using the 24-hour recall method. The mean age of the BPH group ($63.0{\pm}7.9$ years) was significantly higher than that of the non-BPH ($58.8{\pm}7.4$ years). Among many nutrients, the amount of animal fat intake was increased while that of carbohydrate intake decreased in subjects with BPH compared to those with non-BPH. In BPH subjects, the proportion of energy from fat was also greater than in subjects with non-BPH. The logistic regression analysis on the food consumption data showed that the consumption of total animal food was increased while that of mushrooms was decreased in patients with BPH compared to the subjects with non-BPH. The age-adjusted odds ratios and 95% confidences limits for BPH incidence in subjects whose milk and milk products, beverages and alcoholic liquors intake was greater than the median were 1.796 (1.167-2.782) and 1.738 (1.129-2.676) respectively, compared to those in subjects whose intakes were below the median. These results may be applicable in the development of a nutrition intervention and education program toward a reduction in the risk for benign prostatic hyperplasia.
