Rhinitis and sinusitis are among the most common medical conditions in Korea, as well as Western societies. Environmental factors may influence both rhinitis and sinusitis; however, the role of dietary factors in rhinitis and sinusitis is not clear. The present study aims to compare the dietary habit, food consumption frequency, and food preference of elementary school students with or without rhinitis and sinusitis. The demand of their parents for an education program for the dietary prevention against rhinitis and sinusitis was also examined. The survey was conducted with a total of 200 subjects recruited from two elementary schools located in Gyeonggi area of Korea. The subjects consisted of 101 students with rhinitis and/or sinusitis (RS group) and 99 without rhinitis and sinusitis (control group). The students of the RS group were more likely to have habits of eating-out and street food use, to consume bean, peanut, walnut, almond, yogurt, egg, snack, and French fries frequently, and to prefer the types of foods prepared by stir-frying and deep-frying than the control group. The parents who recognized 'school nutrition teachers or food/nutrition-majored specialists' as the most appropriate educator for the dietary education program in the RS group (48.5% of their parents) were less than those in the control group (67.7% of their parents). The present study suggest that students with rhinitis and/or sinusitis may be different from those without the disease(s) in their dietary habit, frequently consumed foods, and preferred type of foods. More epidemiological, intervention, and laboratory studies are needed in order to elucidate the role of dietary factors in the development and prevention of rhinitis and sinusitis, which will have a significant implication to public health.

The purpose of this study was to investigate whether nutrition counseling and exercise could be beneficial to patients with acquired cardiac disease (ACD). Twenty-five ACD patients participated in this program, which was based on guidelines for serum lipid management. To measure the effects of the nutrition counseling and exercise education, outpatients with ACD were selected and randomly assigned to three groups which were a control group, a diet only group and a diet and exercise group. Nine diet only group patients and nine diet and exercise group patients received nutrition counseling or nutrition counseling and exercise education every other week. Patients who served as a non counseled control group did not receive any counseling during the same study period. Various markers of disease risk, including lifestyle, anthropometric indices, eating behaviors, and serum lipid levels were measured before and after the program. The program lasted up to 12 weeks, depending on the individuals involved. Database management and statistical analyses were performed using SPSS 7.5 software. As a result, BMI and %IBW showed decreased trends in the diet only and the diet and exercise group. Food habit scores were significantly increased in the diet only group and the frequency of saturated fatty acid, dietary cholesterol, salty food and instant food intake were decreased in the diet only group. Comparisons of the daily nutrient intakes of the groups showed their total calorie, carbohydrate and protein intake had decreased significantly, and also the total fat and dietary cholesterol intake had decreased in the nutrition counseling group. The serum total cholesterol and LDL-cholesterol decreased after 12 weeks in the nutrition counseling group. The diet and exercise group showed less interest in diet control than the diet only group. These results show that a well-planned nutrition counseling program would reduce the risks of ACD and cardiovascular disease and help to care such diseases.

This study was designed to assess diet and health-related factors of older adults in Korea. Subjects females were 2,660 adults aged 50 and over living in Korea. Males were 847 persons and were 1813 persons. The mean weight and height for males and females were 63.8 $\pm$ 0.3kg / 164.0 $\pm$ 0.2cm and 57.0 $\pm$ 0.2kg /150.6 $\pm$ 0.1cm respectively. BMI (body mass index), body fat, and percent fat were significantly greater in females than in males. The muscle mass and body water were significantly greater in males than in females. Twenty-one percent of total subjects lived alone and 26% with spouse only. Most of the subject's self-reported income was in middle level (65%) or low level (24%). Proportion of subjects who answered 'very poor' or 'poor' on perceived health status was higher in older group. The 50-64 years old group was facing more stress than 65yr and over group. Among male subjects,38.4% were current-smokers and 22.0% were ex-smokers. But only 6.5% of female subjects were current-smokers. Males turned out to have better dietary habits-meal frequency per day, mealtime regularity, regular meal size and balanced eating-than females (p < 0.001). This study revealed that the diet and health-related factors affect nutritional status and chronic diseases of the elderly. For better management and evaluation of health status of the elderly, more effective nutritional assessment tools should be developed.

We surveyed 837 students attending elementary schoolchildren in Korea for health functional foods (HFF) consumption and significant variables for their HFF consumption including demographic characteristics, parental health concern on offsprings, food eating frequency of subjects and beliefs on potential efficacy of HFF by subjects. The consumption prevalence of HFF was 45.9%, and among all types of HFF, nutritional supplements were taken most frequently, followed by apricot extract-fermented products > lactic acid bacteria containing products > EPA/DHA containing products > red ginseng products. HFF consumption was higher in subjects had parents of high education level (p < .05) and those from families with a high socioeconomic status (p < .01) in comparison to each corresponding group. Health concern on offsprings by parents (p < .001) and consumption ratio of HFF by family (p < .001) was higher in consumers than in nonconsumers of HFF. Total score of dietary assessment was higher in consumers than in nonconsumers of HFF (p < .01), and consumers had a more positive view concerning the potential efficacy of HFF than did nonconsumers (p < .001). Most consumers of HFF took HFF when they were healthy (42.5%), and they did not feel special effects through HFF consumption (47.7%). Most consumers of HFF got the information on HFF from family and relatives (24.8%), and most of them purchased HFF at pharmacy or oriental medicine clinics (53.9%). HFF consumers preferred multi-vitamins and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread consumption of HFF by elementary schoolchildren, the reasonable consumption of these products for the contribution to their overall health and well-being should be emphasized through nutrition education for them and their family.

The purpose of this study was to analyze average kimchi intake, general characteristics, frequency of daily meal intake, intakes of vegetables and fruits, and nutrient intakes in four serving size groups based on data from the Korea National Health and Nutrition Examination Survey 2010~2012. The results showed an average amount of kimchi intake in subjects of 115.6 g, ranging from 0 g to 605.94 g. For daily meal intake except snacking according to kimchi serving size, all daily meal intakes increased significantly with increasing kimchi serving size (p<0.0001), and tendency of kimchi intake increased with more eating-out. As kimchi serving size increased, total intakes of vegetables and salted vegetables increased significantly (p<0.0001). However, unsalted vegetables intake did not show significant difference. Intake of fruits also increased with increasing kimchi serving size. As the serving size of kimchi increased, intakes of energy, carbohydrates, protein, fat, sodium, and potassium increased significantly (p<0.0001). For intake of sodium, intakes of all groups exceeded 2,000 mg, which is the recommended level for Koreans. Moreover, the fourth serving size group consumed three times (6,546.35 mg) more sodium than the recommended level.

The objective of this study is to analyze characteristics of high sodium intaker and factors affecting sodium intake using the Korea National Health and Nutrition Examination Survey (KNHANES). For this study we used two statistical methods, the cluster analysis and one-way analysis of variance (ANOVA). Cluster analysis was used to classify groups of sodium intake. For the analysis of the factors affecting sodium intake, we applied the ANOVA. The average daily intake for Korean is about 3,783 mg sodium per day; this amount is high than recommendation of the WTO. The demographic characteristics of people with higher sodium intake were found to be men more so women, and younger men with a higher education. Height, weight and size of a person's waistline were also characteristics of those with higher sodium intake. Also worker, smoker, those without a hypertension diagnosis, as well as those with a higher the drinking rate and higher eating out frequency tended to have a higher intake of sodium. The Ministry of Food and Drug Safety (MFDS) had established a plan to reduce sodium intake to 3,500 mg per day to 2020. To achieve this goal, it is necessary to educate people about high sodium intake, particularly those at higher risk, according to the results of this study. Through these efforts, the social costs of high sodium intake could be reduced, improving national health.

The purpose of this study was to investigate middle school students` perceptions on foodborne illness prevention in relation to their personal hygiene practices. The survey was administered in July, 2007 at one middle school, with a total of 390 students participating. The self-completed questionnaire consisted of several questions regarding the students` awareness of foodborne illness, perceptions of foodborne illness prevention, and personal hygiene practices. T-tests were used to identify the differences in their perceptions of foodborne illness prevention based on gender and Chi square tests were used to identify the relationships between their perceptions of foodborne illness prevention and personal hygiene practices. Eight percent of the respondents experienced foodborne illness at least once a year and 33.8% of them have stopped eating certain foods due to anxiety towards foodborne illness. The students perceived school foods (26.0%) and street foods(17.9%) as the main sources of foodborne illness, and dairy products(20.0%) and fresh fish (19.7%) were considered foods having the greatest potential for causing foodborne illness. Many students were aware of Escherichia coli O157(43.1%) and Hepatitis A(23.3%), but only a few recognized Clostridium botulinum(4.1%) and Salmonella(7.9%), even though these are major foodborne illness-causing pathogens. The students considered foodborne illness prevention very important(mean = 4.33); also, the results showed that many washed their hands 3-4 times (34.1%) and 5-6 times(29.2%) per day. Hand washing frequency was significantly related to the perceived importance of personal hygiene practice as well as to education on safety and sanitation. However, the students` perception on the importance of personal hygiene practices were not significantly different based on having received safety and sanitation education. Ultimately, these results will be used to develop guidelines for effective education on safety and sanitation.

The purpose of this study was to provide basic information on nutrition education for proper meal purchase habits by conducting a survey on the adolescents' meal purchases, which is gradually increasing nowadays. The survey was conducted on 311 middle school students living in Gyeonggi province. The largest number of students (79.1%) received an allowance under '2,000 won'. Among those students who received a daily allowance, 70.7% of students spent under '1000 won' a day on meal purchases. Most students answered 'meal purchase is necessary'. Of the reasons for thinking that meal purchases are necessary, 'for staving off hunger' took the highest ratio (67.1%). As for standards of food choice, the largest number of students answered 'taste' (57.6%). As for frequency of meal purchases, most students answered 'once or twice a week', and with regard to day of the week, 'weekdays' took the highest ratio. As for possibility of balanced nutrition by meal purchases, the answer 'surely possible' took the highest ratio. Asked whether or not one had learned nutrition education on meal purchases, 73% answered 'no'. Asked about the necessity of nutrition education on meal purchases, 'necessary once' took the highest ratio. The most preferred purchase meals were breads, snacks was ranked second, followed by frozen foods, beverages, fast-foods, rice-cakes, flour-based foods, ice-cream, and fruits. To sum up the results, most students perceived that meal purchases are necessary. However, high quality meal purchases were not achieved, as most of the students did not verify nutrition labeling, and placed emphasis on 'taste'. Further, many students wanted nutrition education on meal purchases while only a few had actually received it. Therefore, systemic, regular, and multilateral nutrition education conducted at home, school, and society will contribute to establishing proper meal purchase habits.
