The iron status and its relations with nutrient intake, coffee drinking, and cigarette smoking were evaluated through the blood analysis and 3-day dietary recalls in 102 apparently healthy Korean adults (48 males, 54 menstruating females) aged 20-49 years and living in Daejeon City. Mean values of hemoglobin (Hb) in males and females were 15.5g/dL and 13.2g/dL, mean corpscular hemoglobin concentration (MCHC) 36.0% and 36.8 %, serum iron (SI) 135 $\mu\textrm{g}$/dL and 97 $\mu\textrm{g}$/dL, transferrin saturation (TS) 39.4% and 29.2%, and serum ferritin (Ft) 88.1 $\mu\textrm{g}$/L and 23.4 $\mu\textrm{g}$/L, respectively. For males the prevalences of abnormal values of iron status indicators were 4.2% in Hb, 2.1% in TS, and 4.2% in Ft, and for females 16.7% in Hb, 25.9% in TS, and 35.2% in Ft. Among females 9.3% had abnormal Ft, TS, and Hb, which was considered as iron-defeciency anemia, and 14.8% had abnormal Ft and TS. As a whole, the impaired iron status prevalences were estimated to be 2.1 - 4.2% for males and 9.3 - 35.2% for females. Mean daily intakes of iron and heme-iron were 13.7mg and 1.51mg in males, and 12.3mg and 1.45mg in females. Ft was positively correlated with dietary energy, protein, iron, and vitamin A, Hb with energy and iron, and MCHC with iron and heme iron. Vitamin A also tended to show positive correlations with Hb, SI, and TS. Coffee drinkers taking 3 cups per day or more had higher levels of Hb, MCHC, and Ft in males and MCHC in females, compared to non-coffee drinkers. Higher levels of Hb and MCHC were found in male smokers than in non-smokers. Coffee drinkers took more energy and vitamin A in males and MPF protein in females than non-coffee drinkers. From the above results, it was suggested that the iron status of men was much better than that of women, and the intakes of energy, iron, heme iron, and especially vitamin A were positively associated with the iron status. Cigarette smoking elevated Hb and MCHC, but the effect of coffee drinking on iron staus was not clear. (J Community Nutrition 5(1) : 44∼50, 2003)

This study analyzed the effects of nutrition technicians' hygiene education on cooking workers' performance of hygiene management in order to ensure the security of school meals. The situation of cooking workers' disposition in subject schools was elementary school(51.1%) and middle school(48.9%) and the type of meals was rural area type(54.2%), urban type(36.5%). and island and isolated area type(9.3%). The methods of meals management were single cooking(88.2%) and joint cooking and management(11.8%). The type of distributing meals was distributing in a dining room(93.5%), in a classroom(3.7%), and in both dining room and classroom(2.8%). Nutrition technicians' employment form included regular(53.5%) and daily(88.2%). Their education was junior college graduate(50.2%), university graduate(44.8%). and graduate school students(5.0%). Cooking workers' employment form included daily(88.2%) and regular (11.1%). suggesting that most were regular. Most cooking workers(77.4%) had at least high school certificate. Regarding the situation of cooking workers' disposition in subject schools, the number of student per one cooking worker was found as 91-120(37.2%), 61-90(22.6%). 60 and under(21.l %). 121-15006.7%). and 151 and over(2.5%). Cooking workers' level of performance of hygiene management was post-working stage(66.37/75 marks), pre-working stage(64.22/75 marks). and working stage(20.34/25 marks), The counting of meals articles in a pre-working stage(20.34/25 marks). temperature and required time in a working stage(18.78/25 marks), and machinery equipment and hygiene in a pre-working stage(21.40/25 marks) showed lowest of performance, which suggest poor service of hygiene. Cooking workers' performance of hygiene management by working stage showed the significant difference with school class(p<.001), type of schools with meals(p<.05). state of cooking workers' employment(p<.001), and cooking worker's disposition(p<.05). A working stage showed the significant difference with type of schools with meals(p<.05). A post-working stage showed the significant difference according to type of schools with meals(p<.05), and the methods of meals management(p<.05), and cooking workers' disposition(p<.05). In the execution of hygiene education, individual hygiene was highest(94.8%), followed by the management of machinery equipment and tools(89.7%), food poisoning and microorganism(94.7%), and the method of food treatment(76.4%). A yearly plan of hygiene education included established(83.9%) and not established(l6.1%). Regular education included not executed(25.1%), 2-3 times a month(l6.1%), and more than 4 a month(4.0%) and occasional education was not executed(57.0%), 1-3 times a month(26.3%), and more than 4 a month(l5.7%). In the methods for hygiene education, oral education(95.7%) was used most, followed by demonstration(10.5%), poster/photo(10.5%), video/slide(3.7%), and computer(3.7%). Frequency of improvement and complement of hygiene education included once a month(56.3%), once a year(20.7%), by quarter(l1.5%), and every six months(1l.5%). Newspaper was used most in materials of hygiene education, followed by internet, TV, nutrition technician's reeducation, information exchange between members, educational office's training, and reference book, and educational office's material. and symposium. Cooking workers' assessment of the effect of hygiene education was conducted through observation(56.8%), check table(l5.2%), question(l4.0%), and examination(14.0%). The reason of cooking workers' low level of performance included habitual custom(53.9%), lack of understanding(20.4%), overwork(l4.6%), and lack of knowledge(l1.l%) and the reason of difficulty in hygiene education included lack of time(55.3%), lack of understanding(27.6%), lack of knowledge and information(8.7%), and lack of budget(48.0%).

BACKGROUND/OBJECTIVES: Although some juices affect subjective sleep quality, there is a lack of information on the effect of a specific juice on objective sleep quality and heart rate variability (HRV) during sleep; thus the present study investigated whether a blended juice made from natural extracts influenced sleep quality and HRV during sleep in adults with disturbed sleep. SUBJECTS/METHODS: A randomized, crossover study was conducted on twenty-five adults (15/10, female/male) complaining of difficulty initiating or maintaining nighttime sleep (Pittsburgh sleep quality index [PSQI] ≥ 5). During feeding sessions (FS), subjects received sleep-inducing juice made of natural ingredients (250 mL/trial) twice a day for 8 weeks or non-FS (N-FS) for 8 weeks while maintaining normal activities. Sleep quality and parameters were recorded via wearable actigraph for 7 consecutive days, and PSQI scores were assessed before and after the intervention. HRV was also monitored at rest and during sleep. RESULTS: After receiving the sleep-inducing juice intervention (FS), PSQI scores were significantly decreased (P < 0.001) and correlated with a significant decline in fatigue severity scale and visual analogue scale levels (P < 0.05; both). HRV indices of vagal activity were significantly improved during FS (P < 0.05), and no significant differences in N-FS were observed. Sleep efficiency and total sleep time increased significantly (P < 0.05) and sleep latency, total counts, sleep fragmentation index, and movement index, decreased significantly (P < 0.05, all 4) during FS, with no significant differences-observed during N-FS. CONCLUSIONS: This study results demonstrated that an 8-week course of sleep-inducing juice has led to improve sleep quality, suggesting an enhanced cardiac vagal tone during sleep. Thus, it could be a well-tolerated option for adults with disturbed sleep.

쥐에게 콩과 콩나물, 순수한 genistein을 함유되어 있는 genistein함량을 기준으로 동일하게 급여 (20mg/kg) 시켰을 때, 체내에서 흡수가 되는 속도는 soy, soy sprout, pure genistein군의 순이며 일반소화율은 soy sprout, pure genistein, soy군의 순이었다. 이로써 soy의 genistein은 쉽게 흡수되고 배설되며, 또한 전혀 흡수되지 않고 배설분으로 나오는 양도 세 그룹 중 가장 많은 것을 알 수 있었다. 이는 담즙 등으로 재순환되지 않는 양이 다른 그룹보다 많기 때문이라고 추정되었다. 따라서 생리기능상의 목적으로 isoflavone을 섭취하고자 할 때에는 콩보다는 콩나물형태로의 섭취가 타당할 것으로 생각되며 정확한 결과를 위해서도 사람이 섭식하는 상태의 콩과 콩나물의 isoflvones의 흡수율을 조사할 필요성이 있을 것으로 생각되었다.

The purpose of this study to investigate the relationship between nutrient intake and serum lipid levels in 165 healthy women in Taegu. A convenient method was to assess nutritional intake. Anthropometric measurement of body weight and height were measured and average energy expenditure calculated . The mean body mass index (BMI) was 23.4$\pm$3.1 and it was higher than the mean BMI of Korean women. Obesity rates for the study subjects were 15.7% by RBW (relative body weight : >120%) and 28.5% by BMI(body mass index) ; >25). Daily energy intake was sufficient at 106% of recommended dietary allowances and the energy percentage ration of carbohydrate , fat and protein was 68 : 18 : 14. Mean intake of vitamin A, B1 , niacin , and Ca were higher than RDA. The incidence of hypertension(>140mmHg) and hypercholoesterolemia(>240mg/dl) as 18.2% and 23.6% of the subjects, respectively . Postmenopasusal women showed significantly higher blood pressure, RBW, and ALP (alkaline phosphatase) than premenopausal women. The concentration of cholesterol and average blood pressure in the irregular meal eater group were significantly higher than in the regular meal eater group. Skipping meals and unenvendurnal distribution(no breakfast, or no lunch , and large evening meals) are associated with high total cholesterol level in this population . Especially, the atherogenic index was significantly lower in the regular meal eater group than that in irregular meal eaters. The values for serum cholesterol, triglyceride, blood pressure, BMI, and atherogenic index increased with age in middle-aged women. There was a highly significant correlation between body weight and plasma lipids. HDL -cholesterol was inversely correlated with BMI. The above dta provides valuable information for community program planning and health providers who work with individual female and adults to meet their nutrietional needs to control blood lipids.

To study the factors related to childhood obesity, 75 subjects were selected as an obese group and 75 subjects were selected as a control group according to their obesity index and BMI among the 583 children of 5th and 6th grade in elementary school in Seoul. For each subject, skinfold thickness was measured, information on the characteristics of family, nutrient intake and activity time of the subjects were obtained by questionnarie. The results were summarized as following: 1) Parents' obesity indices of obese group were significantly higher than those of control group(Father's Obesity Index : P<0.01, Mother's Obesity Index : P<0.05). 2) Questions about eating rate and behavior showed that subjects in obese group were significantly faster in their eating rate(p<0.05) and always more eager to eat food(p<0.001) compared to control group. 3) Dietary intake data showed that average daily intake of all the nutrients exceeded Korean recommended dietary allowances for the age group. In female children, fat intakes of obese group were significantly higher than control group(P<0.05). There was no such significant difference in male subjects. 4) Activity time record of subjects reveal that there was a trend for males to spend more time in moderate and high activity and less time in light activity compared to females. Subjects in obese group spent significantly more time for light activity(P<0.001) and significantly less time for moderate activity (P<0.001) compared to subjects in control group. The difference of activity was more pronounced in male subjects. 5) Correlation matrix of the variables showed that obesity index, BMI, and skinfold thickness of the subjects were highly correlated with each other. These indices were positively correlated to parent's obesity indices and the time spent for light activity, but negatively correlated to the time spent for moderate activity. Nutrient intakes were not significantly correlated to obesity indices. Form the results shown above, although both obese and control groups are from high socioeconomic class, obese children tended to come from family with fat parents. They eat fast and are always eager to eat. They tend to eat more fat but are very different from controls in nutrient intake. Obese children are significantly lower in their actinity compared to controls. So, for the prevention and treatment of childhood obesity, it seems to be more important to increase their activity levels.

The purpose of this study was to investigate perceptions of Korean foods and school foodservice satisfaction levels among middle school students as provided by a Korean menu-focused school foodservice. The study subjects included middle school freshmen attending a school providing Korean menus and their parents. A survey questionnaire was administered to obtain information on general characteristics, perceptions of traditional Korean foods, and degrees of satisfaction toward school foodservice. The student subjects had significantly lower interest and preference for traditional Korean foods and less positive perceptions of traditional Korean foods than the parent subjects. In regard to degrees of satisfaction for school foodservice, the students evaluated the current Korean menu-focused foodservice significantly higher than the previous foodservice provided to them during their elementary school days. The parent subjects' also generally reported very high satisfaction levels of the foodservice. The current study findings suggest there are positive effects of Korean-style school foodservice and support its further expansion to other schools. It is recommended that dietary education on the excellence of traditional Korean foods should accompany the provision of Korean-style foodservices in order to better guide adolescents' recognition of the matter.

This study examines the combined effects of caloric restriction on body composition, blood lipid, and satiety in slightly overweight women by varying food density and aerobic exercise. Twenty-three women were randomly assigned to one of two groups for a four-week weight management program: the high-energy density diet plus exercise (HDE: n = 12, $22{\pm}2$ yrs, $65{\pm}7$ kg, $164{\pm}5$ cm, $35{\pm}4%$ fat) and low-energy density diet plus exercise (LDE: n = 11, $22{\pm}1$ yrs, $67{\pm}7$ kg, $161{\pm}2$ cm, $35{\pm}4%$ fat) groups. Subjects maintained a low-calorie diet (1,500 kcal/day) during the program. Isocaloric ($483{\pm}26$ for HDE, $487{\pm}27$ kcal for LDE) but different weight ($365{\pm}68$ for HDE, $814{\pm}202$ g for LDE) of lunch was provided. After lunch, they biked at 60% of maximum capacity for 40 minutes, five times per week. The hunger level was scaled (1: extremely hungry; 9: extremely full) at 17:30 each day. Before and after the program, the subjects' physical characteristics were measured, and fasting blood samples were drawn. The daily energy intake was $1,551{\pm}259$ for HDE and $1,404{\pm}150$ kcal for LDE (P > 0.05). After four weeks, the subjects' weights and % fat decreased for both LDE (-1.9 kg and -1.5%, P < 0.05) and HDE (-1.6 kg and -1.4%, respectively, P < 0.05). The hunger level was significantly higher for HDE ($2.46{\pm}0.28$) than for LDE ($3.10{\pm}0.26$) (P < 0.05). The results suggest that a low-energy density diet is more likely to be tolerated than a high-energy density diet for a weight management program combining a low-calorie diet and exercise, mainly because of a reduced hunger sensation.
