The control of the chronic degenerative diseases becomes a challenge in Korea as the aging of the population progresses. Accordingly, the importance of the control of the hypertension, one of the major chronic degenerative diseases, in the primary health care settings increases. However, such control activities are still minimal. This study gives brief description of how the rural residents who are currently registered for the control of the hypertension feel about the activities of the health centers, subcenters and the CHP posts, in relation to the control of the hypertension. We also describe the knowledge and practice of the registered hypertensive. In general, the knowledge, the acceptance and the satisfaction of the respondents about the hypertension control activities were not very high. Respondents being managed by the health center showed the highest knowledge, acceptance and satisfaction, and those being managed by the subcenters ranked lowest. The knowledge about the hypertension was not satisfactory. There were great variations among the items in terms of the proportion answered correctly. As many as 60% of the respondents take medication regularly but only 4.5% were practicing weight control regularly. Despite some limitations of the study, the results can be very useful for those planning hypertension control programs. The educational materials and the dietary protocols need to be developed in accordance with the regional social and food pattern, so that they can be utilized with minimal modification for each beneficiary. We also suggest to minimize the area a health personnel covers. In other word, running several small health posts at village level would be more effective than running a subcenter at the township level, in terms of the hypertension control.

Vitamin K intake has been reported as an essential factor for bone formation. The current study was conducted under the hypothesis that insufficient vitamin K intake would affect inflammatory markers and bone mineral density in young adult women. The study was a cross-sectional design that included 75 women in their 20s. Physical assessments, bone mineral density measurements, 24-hr dietary recalls, and biochemical assessments for high sensitivity C-reactive protein (hs-CRP) and percentages of undercarboxylated osteocalcin (%ucOC) were performed. An analysis of vitamin K nutritional status was performed comparing first, second, and third tertiles of intake based on %ucOC in plasma. Vitamin K intake levels in the first, second, and third tertiles were $94.88{\pm}51.48\;{\mu}g$, $73.85{\pm}45.15\;{\mu}g$, and $62.58{\pm}39.92\;{\mu}g$, respectively (P < 0.05). The T-scores of the first and third tertiles were 1.06 and -0.03, respectively, indicating that bone mineral density was significantly lower in the group with lower vitamin K intake (P < 0.05). There was a tendency for different serum hs-CRP concentrations between the first ($0.04{\pm}0.02$) and third tertiles ($0.11{\pm}0.18$), however this was not statistically significant. Regression analysis was performed to identify the correlations between vitamin K nutritional status, inflammatory markers, and bone mineral density after adjusting for age and BMI. Serum hs-CRP concentrations were positively correlated with vitamin K deficiency status (P < 0.05). And bone mineral density, which was represented by speed, was negatively correlated with vitamin K deficiency status (P < 0.05). In conclusion, status of vitamin K affects inflammatory status and bone formation. Therefore, sufficient intake of vitamin K is required to secure peak bone mass in young adult women.

The purpose of this study was to investigate the diet of children under the government-funded meal support program. The 143 children (67 boys and 76 girls) participated in this study among $4^{th}-6^{th}$ elementary school students receiving free lunches during the summer vacation of 2007 and living in Gwanak-gu, Seoul, Korea. The subjects consisted of four groups supported by Meal Box Delivery (n = 26), Institutional Foodservice (n = 53), Restaurant Foodservice (n = 27), or Food Delivery (n = 37). A three-day 24-hour dietary recall and a self-administered survey were conducted. In addition, the children's heights and weights were measured. The average energy intake of the children was 1,400 kcal per day, much lower than the Estimated Energy Requirements of the pertinent age groups. The results also showed inadequate intake of all examined nutrients; of particular concern was the extremely low intake of calcium. On average, the children consumed eight dishes and 25 food items per day. The children supported by Meal Box Delivery consumed more various dishes and food items than the other groups. The percentage of children preferring their current meal support method was the highest in those supported by Meal Box Delivery and the lowest in those supported by Food Delivery. We requested 15 children among the 143 children participating in the survey to draw the scene of their lunch time. The drawings of the children supported by Institutional Foodservice showed more positive scenes than the other groups, especially in terms of human aspects. In conclusion, the overall diet of children under the government-funded meal support program was nutritionally inadequate, although the magnitude of the problems tended to differ by the meal support method. The results could be utilized as basic data for policy and programs regarding the government-funded meal support program for children from low-income families.

The purposes of this study were to assess hospital foodservice quality and to identify causes of quality problems and improvement strategies. Based on the review of literature, hospital foodservice quality was defined and the Hospital Foodservice Quality model was presented. The study was conducted in two steps. In Step 1, nutritional standards specified on diet manuals and nutrients of planned menus, served meals, and consumed meals for regular, diabetic, and low-sodium diets were assessed in three general hospitals. Quality problems were found in all three hospitals since patients consumed less than their nutritional requirements. Considering the effects of four gaps in the Hospital Foodservice Quality model, Gaps 3 and 4 were selected as critical control points (CCPs) for hospital foodservice quality management. In Step 2, the causes of the gaps and improvement strategies at CCPs were labeled as "quality hazards" and "corrective actions", respectively and were identified using a case study. At Gap 3, inaccurate forecasting and a lack of control during production were identified as quality hazards and corrective actions proposed were establishing an accurate forecasting system, improving standardized recipes, emphasizing the use of standardized recipes, and conducting employee training. At Gap 4, quality hazards were menus of low preferences, inconsistency of menu quality, a lack of menu variety, improper food temperatures, and patients' lack of understanding of their nutritional requirements. To reduce Gap 4, the dietary departments should conduct patient surveys on menu preferences on a regular basis, develop new menus, especially for therapeutic diets, maintain food temperatures during distribution, provide more choices, conduct meal rounds, and provide nutrition education and counseling. The Hospital Foodservice Quality Model was a useful tool for identifying causes of the foodservice quality problems and improvement strategies from a holistic point of view.

Little data exists on metabolic syndrome (MetS) related with intake, especially for the South Korean. The purpose of this study was to develop and evaluate a food frequency questionnaire (FFQ) for nutritional assessment in the population with MetS in South Korea. Randomly selected female participants, mean age 21.9 years (n = 38) were invited to answer the FFQ twice (FFQ1 and FFQ2) over a nine-month interval and to complete twelve-day diet records (DR) during the months between in South Korea. The correlation coefficients for nutrient intake between FFQ1 and FFQ2 varied from 0.253 (niacin) to 0.573 (cholesterol), and the energy intake-adjusted correlation coefficients ranged from 0.187 for protein to 0.662 for iron. The energy intake-adjusted and de-attenuated correlation coefficients for comparison of FFQ1 and the DRs ranged between 0.277 (vitamin $B_1$) and 0.768 (fiber), and between 0.229 (zinc) and 0.859 (fat) for comparison of DRs with FFQ2. The percentages of study subjects classified into the same quartiles in both the DRs and FFQ1 ranged from 15.8% (vitamin $B_6$) to 47.4% (calcium), and for the same quartiles in DRs and FFQ2 from 13.2% (vitamin $B_1$) to 44.7% (potassium). The FFQ has reasonably good validity and reproducibility. Further research is needed for an assessment of reproducibility and validation of present FFQ in the subjects with MetS.

This study investigated the effect of coffee intake and exercise on the antioxidative activity and plasma cholesterol profile of physically trained rats while they were exercising. Forty eight rats were under either the control diet with water (C) or control diet with coffee (CF) and at the same time they were given physical training for 4 weeks. In terms of physical training, the rats were exercised on a treadmill for 30 minutes everyday. At the end of 4 weeks, animals in each dietary group were subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). Animals in the DE group were exercised on a treadmill for one hour, immediately before being sacrificed. Animals in the AE group were allowed to take a rest for one hour after exercise. TG levels were significantly high in coffee intake group than in control group. Also TG level of AE group was significantly higher than that of BE group. Exercise and coffee-exercise interaction effects were significant in total cholesterol (P = 0.0004, 0.0170). The AE of coffee intake group showed highest total cholesterol levels. HDL-cholesterol was significantly lower in coffee intake group than in control group. Coffee, exercise, and coffee-exercise interaction effects were significant in SOD (P = 0.0001, 0.0001, and 0.0001). The AE and BE of coffee intake group showed higher SOD levels than the other four groups. Catalase activities were significantly higher in coffee intake group than control group. No significant main effect was found in GSH/GSSG. Coffee, exercise, and coffee-exercise interaction effects were significant in MDA levels (P = 0.0464, 0.0016, and 0.0353). The DE and AE of coffee intake group and the DE of control group showed higher MDA levels than the BE of control group. Therefore, coffee intake can promote activities of antioxidant enzyme but it also increases MDA and decreases HDL-cholesterol in physically trained rats.

This study was conducted to search the health food intake behavioral intentions of male workers. The health-related behavior of 150 subjects were compared(smoke, alcohol drink, breakfast, BMI, sleep, exercise and health check). On the basis of the Theory of Planned Behavior, the factors health-food intake behavior were evaluated; there were normative beliefs, motivation for compliance, subjective norms, social influence factors, and barriers as perceived behavior control. The results were showed with five points by the Likert scale and Significance by t-test. The most frequently consumed health food was tea(3.40/4points) followed by healthy drinks(2.49/4). As behavioral beliefs, if consumption of 'nutritional supplements'(3.61/5) and 'fatigue recovery'(3.62/5) received the highest scores. As a result, the idea of 'nutritional supplements'(3.94/5) and 'fatigue recovery'(4.06/5) were the important aspects, but others were also positively evaluated. As a sub-factor of subjective norms on normative beliefs, The highest social groups to encourage consumption of health food were parents (3.93/5), and the lowest were doctors (3.02/5). The most influential people were doctors (3.67/5) and spouses (3.65/5). Barriers to consumption health food were side effects (1.09/5) and price (2.08/5). Taking Ginseng products and other processed foods (juice, honey, bamboo, etc.) were correlated with health concern (p<0.05). Taking traditional stamina foods was correlated with dietary habit recognition (p<0.05). Mineral intake was positively correlated with age. Healthy drinks was negative (p<0.05). Minerals and supplement consumption were correlated with the practice of healthy behavior (p<0.01).

BACKGROUND/OBJECTIVES: The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS: This study is based on the 1998-2012 KNHNES. Analysis data on 54,700 subjects aged 19 years and older were obtained from health behavior interviews and the 24-hour dietary recall method. RESULTS: Daily kimchi consumption and portion size of kimchi decreased significantly from 1998 to 2012 (adjusted P for trend < 0.0001). Meanwhile, daily consumption of both non-salted vegetable and fruit with and without kimchi did not significantly change between 1998 and 2012. Reduced consumption of kimchi, non-salted vegetable, and fruit was observed for both genders as well as daily meal episodes and cooking locations. Male and female subjects with insufficient non-salted vegetable and fruit intake were increased 1.4 times and 1.3 times, respectively, in 2012 than 1998. All subjects consumed at least 400 g/day of non-salted vegetable, fruit, and kimchi in each survey year, although they consumed insufficient amounts (< 400 g/day) of non-salted vegetable and fruit without kimchi. CONCLUSIONS: Since Koreans generally consume high amounts of fermented vegetables, including kimchi, total vegetables and fruit. Consumption of these foods by the Korean adult population reached 400 g, which is the recommended intake of the WCRF/AICR. Based on this result, it is necessary to promote consumption of kimchi in the Korean population and research the development of low sodium kimchi in the future.

BACKGROUND/OBJECTIVES: The prevalence of atopic dermatitis in infants is increasing worldwide. However, the nutrient intake status of infants with atopic dermatitis has not been studied properly. This study was conducted to compare the nutrient intake status of infants in the weaning period with atopic dermatitis by feeding type. MATERIALS/METHODS: Feeding types, nutrient intake status and growth status of 98 infants with atopic dermatitis from age 6 to 12 months were investigated. Feeding types were surveyed using questionnaires, and daily intakes were recorded by mothers using the 24-hour recall method. Growth and iron status were also measured. RESULTS: The result showed that breastfed infants consumed less energy and 13 nutrients compared to formula-fed or mixed-fed infants (P < 0.001). The breastfed group showed a significantly lower intake rate to the Dietary Reference Intakes for Koreans than the other two groups (P < 0.001). In addition, they consumed less than 75% of the recommended intakes in all nutrients, except for protein and vitamin A, and in particular, iron intake was very low, showing just 18.7% of the recommended intake. There was no significant difference in growth by feeding type, but breastfed infants showed a significantly higher rate of iron deficiency anemia (P < 0.001). CONCLUSIONS: Continuous management programs should be prepared for breastfed infants with atopic dermatitis, who are in a period when rapid growth takes place and proper nutrient intake is essential.

The dietary intake of whole grains is known to reduce the incidence of chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. To investigate whether there are anti-adipogenic activities in various Korean cereals, we assessed water extracts of nine cereals. The results showed that treatment of 3T3-L1 adipocytes with Sorghum bicolor L. Moench, Setaria italica Beauvois, or Panicum miliaceum L. extract significantly inhibited adipocyte differentiation, as determined by measuring oil red-O staining, triglyceride accumulation, and glycerol 3-phosphate dehydrogenase activity. Among the nine cereals, P. miliaceum L. showed the highest anti-adipogenic activity. The effects of P. miliaceum L. on mRNA expression of peroxisome proliferator-activated receptor-${\gamma}$, sterol regulatory element-binding protein 1, and the CCAAT/enhancer binding protein-${\alpha}$ were evaluated revealing that the extract significantly decreased the expression of these genes in a dose-dependent manner. Moreover, P. miliaceum L. extract changed the ratio of monounsaturated fatty acids to saturated fatty acids in adipocytes, which is related to biological activity and cell characteristics. These results suggest that some cereals efficiently suppress adipogenesis in 3T3-L1 adipocytes. In particular, the effect of P. miliaceum L. on adipocyte differentiation is associated with the downregulation of adipogenic genes and fatty acid accumulation in adipocytes.
