This study was conducted to investigate the cross-sectional associations between dietary factors and the risk of metabolic syndrome (MetS) in 12,755 subjects (males 5,146, females 7,609) aged 19 years or above using data from the 4th (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES). The prevalence of MetS in Korean adults was 23.6% (males 26.1%, females 20.9%) with the criteria for modified National Cholesterol Education Program Adult Treatment Panel III. While males had a higher prevalence of abdominal obesity, hyperglycemia, hypertriglyceridemia, and high blood pressure than females, the prevalence of low HDL-cholesterol level was higher in females than in males. Among dietary guidelines, the response of 'yes' for asking practice of 'avoiding salty foods', and 'eating moderately and increasing physical activity for healthy weight' were significantly associated with the decreased risk of MetS in both males and in females. Especially, the risk of MetS was significantly lower in the subjects that responded the practice of all items of Korean Dietary Guidelines. Significantly negative associations with MetS were also found in the responding for practice of 'limiting consumption of alcoholic beverages' in males, and taking dietary supplements in females. Skipping breakfast was positively associated with the risk of MetS. In conclusion, dietary behaviors such as having breakfast, practice of dietary guidelines, and food consumption in moderation could modify the prevalence of MetS, and our findings could be useful for establishing guidelines for preventing MetS.

The purpose of this study was to suggest an educational direction to aid in formulating a dietary life that is suited to Korea's multicultural families. This was achieved by analyzing the dietary life of immigrant women from multicultural families in Daegu. The study was carried out with 94 immigrant women form multicultural families who were served by public health center A (20 women), public health center B (47 women) and public health center C (27 women). Their home countries were China (55.3%), Vietnam (37.2%), Philippines (3.2%), Japan (2.1%), Uzbekistan (1.1%) and Thailand (1.1%). When the scores of their dietary balance were compared on the basis of the time they have been in Korea (Less than 1 year, 1~3 years, more than 3 years), we found that the score of immigrant women who stayed for less than 1 year was higher than those who stayed for more than 3 years (p<0.05) in terms of their intake of meats, fishes, potato, calcium, and carbohydrate. When subjects were asked about Korean food they wanted to learn how to cook, 30 different types of food were selected and 95.5% of the respondents wanted to learn in detail how to cook Korean food. The place most suitable for them to learn cooking was college (30.3%), while the house of their husband (2.2%) was lowest. Therefore, it seems that a college, public health center or welfare center are good places for immigrant women from multicultural families to participate in an education program that is designed to teach them how to cook Korean food.

This study developed Bucheon customized children meal hygiene central control point (CCP) to promote practical hygiene and safety management in a children meal supply organization in Bucheon. Education was administered to 54 organizations using the developed CCP, and the study evaluated kitchen hygiene management improvement effects. When the effects of hygiene education in eight categories (CCP 1~8) were examined, total scores increased by 9.31 from $22.36{\pm}5.039$ before education to $31.67{\pm}3.262$ with a statistically significant difference (p<0.001). After CCP education, personal hygiene management, food material management, cooking management, serving management, facility and equipment management improved significantly. The result demonstrates that CCP education was effective for kitchen hygiene management. Using CCP education, overall CCP education items were significantly improved, but there was almost no significant increase in the non-relevant item of CCP education. As there was an average difference in the non-relevant item of CCP education after follow-up evaluation, CCP education had an overall effect on hygiene and safety improvement. Based on the above result, the effect could be potentiated if CCP is complemented, if a systematic hygiene management manual is developed for the nationwide children meal supply organization, and if CCP education media is continually developed along with education.

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.

The purpose of this study was to measure the nutrition knowledge, dietary attitude, eating behavior, physical ability and locomotion of 5-year-old-children, and thereby to provide the fundamental information necessary to develop a nutritionrelated physical education program. A survey was performed on 143 5-years-old boys and 113 girls. The results were as follows. The average score in the nutrition knowledge item, was 7.22 out of a possible 10 points; in the dietary attitude item, 32.46 out of 50 points; in the eating behavior item, 26.67 out of 40 points. According to body measurement, there was a significant difference in height by gender (p<0.05), Significant differences in muscle mass and basal metabolic rate were also observed by gender (p<0.001). Gender also influenced the flexibility and reflexibility (p<0.001), with significant difference in balance of the right side (p<0.01). Although this study was limited by its cross-sectional study design, the body muscle (p<0.05) and basal metabolic rate (p<0.05) were observed to have a positive relation with nutritional knowledge. In addition, there was a significant positive correlation between nutritional knowledge and dietary attitude (p<0.01). According to the results, it is necessary to develop a long-term and systematic program with the combination of nutrition and physical education to develop correct dietary habits and for the balanced growth of children.

BACKGROUND/OBJECTIVES: The scientific evidence of a sodium-obesity association is limited by sodium intake assessments. Our specific aim is to synthesize the association between dietary sodium intake and obesity across the sodium intake assessments as evidenced by systematic reviews in adults. SUBJECTS/METHODS: A systematic search identified systematic reviews comparing the association of dietary sodium intakes with obesity-related outcomes such as body mass index (BMI), body weight, waist circumference, and risk of (abdominal) obesity. We searched PubMed on October 24, 2022. To assess the Risk of Bias in Systematic Reviews (ROBIS), we employed the ROBIS tool. RESULTS: This review included 3 systematic reviews, consisting of 39 unique observational studies (35 cross-sectional studies and 4 longitudinal studies) and 15 randomized controlled trials (RCTs). We found consistently positive associations between dietary sodium intake and obesity-related outcomes in cross-sectional studies. Studies that used 24-h urine collection indicated a greater BMI for those with higher sodium intake (mean difference = 2.27 kg/m²; 95% confidence interval [CI], 1.59-2.51; P < 0.001; I² = 77%) compared to studies that used spot urine (mean difference = 1.34 kg/m²; 95% CI, 1.13-1.55; P < 0.001; I² = 95%) and dietary methods (mean difference = 0.85 kg/m²; 95% CI, 0.1-1.51; P < 0.05; I² = 95%). CONCLUSIONS: Quantitative synthesis of the systematic reviews has shown that cross-sectional associations between dietary sodium intake and obesity outcomes were substantially different across the sodium intake assessments. We need more high-quality prospective cohort studies and RCTs using 24-h urine collection to examine the causal effects of sodium intake on obesity.

This study analyzed the reasons for continuing education among dietitians. An internet-based survey of 622 dieticians was conducted from August 31, 2012 to September 12, 2012. Based on data from the Participation Reasons Scale (PRS) questionnaire, factor analysis was conducted by principle component analysis for the extraction of major factors. Subsequent reliability analysis was performed by assessing Cronbach's ${\alpha}$. The ANOVA-test was performed to compare the participation reason scores for each factors according to general characteristics. Statistical analysis was performed using SPSS ver.17.0, and P<0.05 was considered significant. Factor analysis for the participation reasons revealed four types of factors. These factors were "maintenance and development of professional competencies", "interaction and responsibility of professionals", "job stability and personal profits" and "services for customers" respectively. Among the participation reasons, "maintenance and development of professional competencies" was the first reason with a 29.34% variance. In addition, the participation reasons for continuing education differed according to age (P<0.05), the highest level of education (P<0.05), workplace (P<0.01), and work experience in dietetic area (P<0.001). In conclusion, continuing education programs for dietitians should focus on effectively developing and promoting professionalism.

Objectives: The purpose of this study was to develop a Na-reduction education program and apply it for cooks who prepare meals in day-care centers. To development of the program was based on increasing the self-awareness of salinity, eating behaviors and enforcing skills of low-Na cooking. Methods: The study was carried out from April to October in 2013, fifty five cooks participated in this program. The Na reduction program composed of 4 sessions of education which included a 90-minute lecture and self-reevaluation of personal salt-sensitivity degree and three low Na recipe cooking classes. In order to measure the effectiveness of the program, the pretest and posttest of salinity of the soups provided by day care centers was conducted at registration and 5 month after the program with the same menu. Results: After the conduct of the program, salimeter using rate was increased from 8.2% to 94.6% after the program and the other measuring instruments using rate was gradually increased. We observed that the score on eating behaviors increased 1.51 points from 38.80 to 40.31 after the intervention program (p < 0.001). Further, increased knowledge and skill provided by the intervention program resulted in improved Na-reduction cooking capability. According to the results from analyzing the soup salinity, the salinity in watery soup was significant reduced from 0.556 to 0.449 0.107 and soybean-paste soup was significant reduced from 0.669 to 0.551 after the intervention program (p < 0.001). Conclusions: As the result of fact, the intervention programs that was based on self-reevaluation, to enforce practical skill and consciousness was effective to serve low sodium menu at day care centers.

Background: Breast cancer is one the most common cause of cancer-related deaths among women worldwide. The aims of this study were to investigate the impact of dietary factors and health status indicators on breast cancer (BC) incidence. Materials and Methods: Risk factor data (RFD) of 89,404 individuals (15-64 years old) were gathered by questionnaire and laboratory examinations through a cross sectional study from the Non-Communicable Disease Surveillance Centre (NCDSC) of Iran. BC incidences of all provinces through 2001-2006 segregated by age and gender were obtained from the Cancer Registry Ministry of Health (CRMH). Results: a significant positive relationship was seen between diabetes mellitus, fish comsupmption, percent of academic education and non-consumption of fruit, and breast cancer in women. However, non fish consumption, percent age illiteracy and taking fruit showed a significant negative relationship with the incidence of breast cancer. In addition, multiple linear regression analysis showed associations among percentage with academic education, fruit consumption and diabetes. Conclusions: We conclude that dietary factors such as fish and furit consumption, dairy products, health status indicators, academic education, and some diseases like diabetes mellitus can affect the BC incidence, although the results of ecologic studies like this must naturally be interpreted with caution.
