The purpose of this study was to evaluate the prevalence of obesity, dietary habits, and nutritional status by age among low-income women, using data from the fourth Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women aged 20 and over. The subjects were classified into four groups by age. Dietary data from 24-hr recall methods were used to analyze nutritional status. The prevalence of obesity in the 50~64 years age group was significantly higher than those of the other age groups. Among age groups, malnutrition was the highest in the 65-and-over age group. It appears that women in the 20~29 and 65-and-over age groups were the highest nutritional risk. The percentage of carbohydrates in total energy intake was higher and the percentages of protein and fat were lower in the 65-and-over age group than other groups. Frequency of skipping breakfast was lower in women aged 65-and-over, and moderate physical activity significantly decreased with increasing age. Awareness of dietary guidelines was higher in women aged 30~49 years than other groups, whereas it was lower in those aged 65-and-over years. Adherence to dietary guidelines of 'eating a variety of foods from each food group' was significantly lower in women aged 65-and-over years than those of other groups. However adherence to dietary guidelines of 'eating breakfast everyday with a pleasant mind' was significantly lower in women aged 20~29 years than those of other groups. Therefore, this study shows that low income women have various nutritional problems by age group, and we should support a tailored approach to improve their nutritional status.

This study aims to evaluate the degree of malnutrition of children by three nutritional indicators-Weight for Age, Hight for Age, Weight for Height. The results are as follows; The average height and weight of children are much lower than Korea average height and weight. In terms of Weigh for Age, 20-40% of the samples belongs to below-2 standard deviation from the mean of reference group. 90% of the samples falls into the region below the mean. The standard deviation score indicates negative sign for eighty to ninety percent of the samples. The malnutrition of the samples is also confirmed in terms of Height for Age. In terms of Weight for Height, the mean of the samples is not significantly different from that of the reference group. Tests of the nutritional status under basis of three nutritional indicators show that approximately 50% of the samples had suffered from malnutrition and 17% of the samples have suffered from malnutrition.

This study was carried out to evaluate high-school students' nutrient intakes according to the status of depressive trends, and to analyse the in physical and mental health status. The volunteers were 560 high school students selected from 8 provinces, but 511 students were analyzed. A was used for evaluation, The questions were composed in consideration of socio-demographic characteristics, physical health condition by CMI, mental condition assessed by a modified Zung's self-rating depression scale (SDS), and the evaluation of food consumption by a 24 hours recall method. The family situations of the subjects were mostly nuclear family(73%), agricultural work(53%), and having religion(53%). Only 3% of the students suffered depression where as 19% showed depression trendencies. The individual factors that affected their mental condition were family farming and consciousness of academic accomplishment. The health status counted with CMI was 6.2/20 scores. The non-depressed trend group of students had a lower score of CMI than others. The overall nutrient intakes of students were low compared with the Korean RDA for adolescents. The Mean Adequacy Ratio(MAR) of nutrient intakes was only $0.45{\pm}0.23$. Iron, vitamin A, and riboflavin intakes were significantly low and correlated with depressive trend score. The result from the regression analysis showed that CMI, study accomplishment, and vitamin A were the most significant factors influencing mental condition. We concluded that Korean rural high-school students were healthy in mental condition and showed lower rates of depression academic. For there more we could say that the intakes of iron and vitamin A also influenced mental health. Findings confirmed the need of becoming hopeful job of farming and better nutritional status. These situations would be necessary for students to ameliorate the quality of rural living.

BACKGROUND/OBJECTIVES: Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. SUBJECTS/METHODS: A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. RESULTS: Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. CONCLUSIONS: Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

The purpose of this study was to evaluate on nutrient intake status and diet quality of middle and old aged vegetarian women in Korea, The research group was composed of vegetarian women (n=91), all of them were Seven Day Adventists, who had been on vegetarian diets, over 20 yrs. Their anthropometric measurements, dietary intakes, and diet quality indices were compared to omnivores (n=122). The average age of vegetarians and omnivores were 61.8 yrs and 60.3 yrs, respectively. The mean daily energy intakes of vegetarians and omnivores were 1428.8 kcal and 1424.5 kcal, respectively and there was no significant difference. The vegetarians consumed significantly lower intakes of protein (p < 0.05), zinc (p < 0.001) and vitamin $B_{2}$ (p < 0.05) compared to omnivores. In the diet quality, zinc and vitamin $B_{2}$ nutrient adequacy ratio (NAR) of vegetarians were significantly lower than those of omnivores. Mean adequacy ratio (MAR) of vegetarians and omnivores were 0.80 and 0.77, respectively and there was no significant difference. The KDDS (Korean's Dietary Diversity Score) of vegetarians and omnivores were 3.7 and 4.0, respectively, and there was significant difference (p < 0.01). The KDQI (Korean's Diet Quality Index) of vegetarians (1.5) was significantly lower than that (2.1) of omnivores (p < 0.001). In conclusion, vegetarian women have low intake status of protein, zinc and vitamin $B_{2}$, and partly low diet quality. Therefore it was needed that well planed diets to replace the nutrients supplied from excluded food groups in middle and old aged vegetarian women.

This study was performed to suggest a new efficiency measurement indicator is necessary for evaluating management efficiency of food service operations in contract-managed foodservice companies, to distinguish efficient food service providers and inefficient ones by measuring comparative efficiency among food service operations, and to provide guidance for effective management through showing benchmarking targets for improving inefficient food service providers. The subjects of this study were the 93 B&I foodservice Operations of a domestic contract food service company. The analysis was conducted using CCR model in DEA model. A software, 'Frontier analyst', was used for the analysis. Based on the results derived from comparison of efficiency evaluation classified by providers with use of DEA, it was possible to identify efficient food providers and inefficient providers, and subsequently provide benchmarking guidelines for improvement of the inefficient groups. In analyzing the differences between the results of DEA efficiency evaluation by detailed operation status of food service providers, there was significant difference of efficiency outcomes in terms of contract types, while there was no significant difference in terms of business condition.

There were numerous evidences that subjective health evaluation was a powerful indicator for morbidity and mortality in many countries. Since self-rated health (SRH) was a reasonable health measure, identifying predictors for SRH would be beneficial for assessment of overall health, monitoring health status, and development of health promotion programs. Health risks, health behavior, socioeconomic characteristics and social capital were potential indicators for SRH. We examined association. between SRH and indicators such as health risk factors, subjective living condition, income, education level and dietary variety score. Total 4,262 subjects, aged between 20 and 69 years old, were selected from KNHANES 2001; those who completed health examination, nutrition survey, and provided their socioeconomic information. Results of logistic regression showed that it was likely to have better SRH for those who were younger, male and have higher education, higher income, better living condition, no metabolic syndrome and higher dietary variety.

A survey was performed to provide current information on professional catering companies. Twenty-three catering companies out of thirty-eight(60% recovery) responded the survey for December in 1998. Foodservice establishments managed by 16 small-middle sized catering companies provided an average of 11,200 meals daily, while those managed by major and small-middle sized catering companies were mainly office(72.2%, 57.1%) and school foodservice(15.2%, 26%). The rates of sales of major catering companies and small-middle sized catering companies increased 24%, 30% respectively in 1998. Self-evaluation in catering companies was conducted for sanitary management. Unsatisfactory results from self evaluation were found in three categories, such as, measurement of internal temperature of food materials at reception, ventilation system in the working area, and hand-washing stations with equipment cleaning and sanitizing facilities in front of the working area. Most catering companies expressed a willingness to apply the Hazard Analysis Critical Control Point (HACCP) system from this survey. $\ulcorner$Professional catering business has arisen as an area requiring more consideration and further study for the production of a safe food.$\lrcorner$

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.
