The use of semiquantitative food frequency questionnaires to estimate dietary intake has become widespread in nutritional epidemiologic studies. It had been suggested that knowledge about a person's usual portion size of each meal in addition to consumption frequency will improve the accuracy of this method. This study was performed to investigate the dietary intake status(nutrient, food, and dish intake) and one portion size of commonly consumed food and dishes to develop a semiquantitative food frequency questionnaire that will be used to expore the relationship between the incidence of cardiovascular disease and diet in Korean women after menopause. Intake of food or dish in 123 elderly women were measured by 3-day food records in March to May, 1996. The results obtained in this study were summarized as follow : 1) Calcium, vitamin A, and vitamin E intakes were less adequate than Recommended dietary allowances(RDA). 2) The subjects who consumed more than 20% of the energy from fat were 35% and the subjects consumed dietary cholesterol more than 300mg were 18$\%$. 3) The most frequently consumed foods or dishes by the subjects were Korean cabbage kimchi〉cooked rice, well-milled〉laver〉apple〉strawberry〉mixed rice〉soybean soup. 4) The major dish groups which contributed to most daily nutrient intakes were cooked rice, Korean cabbage kimchi, soybean soup because of large amount and high frequency of intake although they do not contain large amount of most nutrients. 5) One portion size of commomly consumed foods and dishes in elderly women was different from one portion size suggested in the Korean nutrition society. This study provides information for the design of data-based semiquantitative food frequency questionnaire. for Korean elderly women. In addition, they may be useful to health care planners or nutrition educators. (Korean J Community Nutrition 2(4) : 578-592, 1997)

비밀봉 방사성물질의 취급 사고시 방사성핵종은 흡입과 취식의 두 가지 경로로 섭취될 수 있다. 이때 일상 감시처럼 하나의 섭취경로만 가정하여 예탁유효선량을 평가하면 심각한 오차를 유발할 수 없다. 이러한 잠재 오차를 제시하기 위해 총 섭취에 대한 흡입섭취의 비율을 달리할 때 예탁유효선량의 변동을 분석하였다. $^{241}Am$(AMAD 5 ${\mu}m$, 흡수형 M)을 대상으로 핵종의 생물역동학적 모델과 데이터를 이용하여 여러 흡입섭취 분율에서 폐, 소변 및 대변에 대한 바이오어세이 측정치를 모의하였다. 섭취 3일 후 예상 측정치를 이용하고 단일 경로 섭취를 가정한 경우 평가된 예탁유효선량의 잠재 오차는 -100%에서부터 많게는 +34,000%에 이르는 것으로 나타났다. 흡입섭취가 있을 때 대변만 분석하면 큰 오차가 발생하였다. 섭취경로 오판에 따르는 선량평가의 오차를 줄이기 위해 두 종류의 바이오어세이를 이용하는 전략을 제안하였다.

Mean daily excretion of Ca, P, and Fe were measured in 49 healthy young Koreans(23 males and 26 females) form urine and feces samples cellected for three days. Dietary intakes of the subjects during the study periods were calculated from intake records. Main results of the study are as following: 1) Mean daily urinary, fecal, and total Ca excretions were 162$\pm$20mg, 346$\pm$39mg, and 508$\pm$50mg, respectively in males and 154$\pm$16mg, 262$\pm$26mg, and 416$\pm$24mg, respectively in females. The mean values of the two groups were not significantly different. 2) Mean daily urinary, fecal, and total P excretions were 751$\pm$45mg, 384$\pm$26mg and 1135$\pm$56mg, respectively in males and 552$\pm$29mg, 335$\pm$34mg and 894$\pm$50mg, respectively in females. Urinary and total P excretion in males were significantly higher than females(p<0.01), but such differences disappeared when the excretions were calculated per kg body weight. 3) mean daily fecal Fe excretions were 12.8$\pm$0.9mg in males and 10.1$\pm$0.8mg in females. The mean value in males was significantly higher than that in females(p<0.05) but when calculated per kg body weight, both groups excreted 0.2mg/kg body weight. 4) Mean daily intake levels of the minerals estimated from three day food intake records were Ca 543mg, P 1136mg, and Fe 14.3mg in males and Ca 533mg, P 869mg, Fe 10.8mg in females. These intake levels seem to be sufficient to supply the daily losses of the study subjects except P in females. However, the problem of estimating dietary intake levels by food intake record should be recognized. Especially females in the study are in menstration age and their Fe losses in the menstration (estimated to be 0.5mg of available Fe per day) should be also supplied in the diet.

This study was conducted to investigate instant coffee-mix intakes and its relations with anthropometric measurements, nutrient intake, and blood lipid in Gangneung and Samcheok residents. Coffee-mix is a mixture of instant coffee, sugar and coffee-creamer. It is a standardized convenience food in Korea. Recently, Koreans appear to consume too much of instant coffee-mix. The respondents of this study were 218 Koreans (Gangneung region 133, Samcheok region 85). The average age was 56.0 years (male), 57.5 years (female). They were divided into 2 groups, the instant coffee-mix drinkers and the non-drinkers. The nutrient intake and anthropometric measurements and their relations with coffee-mix intakes were analyzed (nutrient intakes were calculated by converting per 1,000 kcal and adjusted by age, region). As for male, body fat was significantly higher in coffee-mix drinkers (18.1 kg, 25.0%) than in non-drinkers (17.1 kg, 23.8%). In the case of females, serum triglyceride was significantly higher in coffee-mix drinkers (109.1 mg/dL) than in nondrinkers (102.9 mg/dL). Coffee-mix intakes and coffee-mix's contributions to energy were higher for participants from Samcheok (21.2 g, 4.7%) than those from Gangneung (16.6 g, 3.4%). In addition, for Samcheok, coffee-mix's contribution to energy was significantly higher in male (5.6%) than in female (4.2%). Coffee-mix intakes and energy contribution of coffee-mix were not significantly correlated with anthropometric measurements. Only HDL-cholestrol showed significantly negative correlation with coffee-mix's contributions to energy. Based on the above results, we conclude that usual instant coffee-mix intake may increase intakes of sugar and fat and exert negative effects on serum lipids. Therefore, it is needed to control too much instant coffee-mix intake in the dietary management of rural residents.

Although it is well known that cancer patients suffer from malnutrition, there are few published studies on malnutrition in outpatients receiving chemotherapy in Korea. This study aimed to evaluate nutritional risk in oncology outpatients receiving chemotherapy and to show the baseline data to set up nutritional management programs for cancer patients. This is a retrospective observational analysis on 1,962 patients referred for nutritional education before or during chemotherapy at Seoul National University Hospital Cancer Center from January 2006 to May 2007. According to a malnutrition screening tool, the proportion of patients having malnutrition risk was 23.0%. In the case of upper gastrointestinal cancer, more than 50% of patients were assessed as being at the risk of malnutrition. They showed more than 7% weight loss compared to their usual body weight and poor oral intake; energy intake was less than 100% of Basal Energy Expenditure(BEE) and protein intake was less than or equal to 0.77 g/kg/d. However, only 6.3% of breast cancer patients had risk of malnutrition and their oral intake was better; energy intake was 121% of BEE, and protein intake was 0.90 g/kg/d. Outpatients receiving chemotherapy had different nutritional risk depending on their cancer site. Nutritional management program should be conducted differently, depending on the cancer site and upper gastrointestinal cancer patients at high risk of malnutrition should basically have nutritional assessment and intervention.

The purpose of this study was to examine bowel habits, dietary habits, and nutrient intake of constipated adults, and the effects of prune products on relieving constipation symptoms. Fifty one adults with self-reported constipation (mean age 23 years, range 19-41 years, 10 males and 41 females) participated in this study. After a baseline survey on bowel habits and dietuy habits, participants were asked to consume at least 50 g of prune and 200 ml of prune juice per day during a 4-week period in addition to usual diet. Nutrient intake was estimated by a 24 hour recall at the baseline and once every week by diet records during the intervention. Data were analyzed after classifying the subjects into mild constipation group and severe constipation group by the severity of the symptoms. During the intervention, the subjects with mild constipation consumed 56 g of prunes (about 5.6 fruits) and 200 ml of prune juice, and the subjects with severe constipation consumed 59 g of prunes (about 5.9 fruits) and 207 ml of prune juice. Average intakes of energy, dietary fiber and water of the subjects in the mild constipation and severe constipation group increased during the intervention compared to the baseline. Average dietary fiber intake of the mild constipation and severe constipation groups significantly increased from 12.5 g and 11.6 g at the baseline to 18.5 g and 16.8 g after consuming prune products, respectively. These changes were accompanied by an increase in the number of bowel movements, a decrease of defecation time, a change to a softer stool consistency, and a decrease of abdominal pain during defecation. Seventy two subjects answered that prune products were effective to improve their overall constipation symptoms. Our data show that supplementation of prune products is effective to provide energy, dietary fiber and water, and to relieve constipation symptoms for constipated adults.

From the onset of puberty or during its progress, eating and health behaviors are important in establishing optimum growth and healthy fitness in middle school students. This study investigated the dietary and health behavior of first grade middle school students(male 260, female 255) selected from 3 middle schools in Suwon. Results were analyzed using the statistical program(SAS ver. 8.1). Usual dietary habits were scored by the Likert scale of 5 points and obtained the mean and standard deviation. Obtaining significant gender difference, chi-square and student t-test were also done. Daily breakfast intake was 70% of all students but some of them ate alone(27.3%). The amount of food intake was slightly less(34.8%) but sufficient food for dinner(53.2%). The purpose of each meal was solving hunger(57.4%). However, they want to change their current eating habits because of an unbalanced diet. Usual dietary habits were similar in gender, but 'apply nutrition knowledge' and 'consider food combination' were better in female students (p<0.01), 'regular meals' were higher in males(p<0.01). With respect to health behavior, the subjects went for daily walks for less than an hour(39.9%) and got 7-8 hours of sleep per day(33.8%). The amount of sleep was sufficient(22.6%) in males but in insufficient (33.8%) in female students(p<0.01). Weight control efforts for reducing(female 27.5% male 20.8%) and for increasing(male 10.6%) differed according to gender(p<0.01). As the result of the above analyses, the direction of nutrition education would be oriented to the nutrition knowledge and food combination applying to the diets of male students and regular meals for females. And also sleep dissatisfaction needs to be altered with taking care weight control trials.

본 연구에서는 20대 초반 한국 여성의 짠맛 역치 및 선호도를 측정하여 음식섭취빈도법을 통해 추정한 나트륨 섭취량과의 연관성을 분석하고, 자기 평가 짠맛 선호도와 관련되어 있는 나트륨 섭취 관련 식행동과 나트륨 섭취 기여 음식을 조사하였다. 자기 평가 짠맛 선호도는 음식섭취빈도법을 이용하여 추정한 나트륨 섭취량과 유의한 양의 상관관계에 있었으며, 나트륨 증가 식행동과 양의 상관관계에 있었고, 나트륨 감소 식행동과 음의 상관관계에 있었다. 나트륨 섭취와 관련된 식행동 중에는 식탁에서 소금과 양념간장의 사용, 외식과 배달음식의 빈도, 국, 찌개, 국수류의 국물 섭취, 레토르트나 가공 식품의 이용, 생채소의 섭취, 싱거운 맛에 대한 수용태도 등의 항목이 자기 평가 짠맛 선호도와 유의한 관련성이 있었으며 나트륨 섭취 기여음식 중에는 라면, 순두부찌개, 총각김치 및 김치를 이용한 음식 등이 자기 평가 짠맛 선호도와 유의하게 관련되어 있어, 짠맛 선호도가 이들 식행동 및 음식을 통해 높은 나트륨 섭취와 관련되어 있는 것으로 생각된다. 예상과는 달리 짠맛 검출 및 인식 역치는 자기 평가 짠맛 선호도, 나트륨 섭취량, 나트륨 증가 및 감소 식행동과 유의한 상관관계를 보이지 않아 식품체계가 아닌 염화나트륨 수용액을 이용한 짠맛 역치보다는 자기 평가된 짠맛 선호도가 개인의 평상시 나트륨 섭취량을 간접적으로 평가할 수 있는 더 좋은 지표로서 생각된다. 결론적으로, 자기 평가 짠맛 선호도는 나트륨 섭취와 관련된 식행동과의 연관성으로 인하여 평상시 나트륨 섭취 정도를 잘 반영하는 것으로 나타났으며, 개인의 나트륨 섭취 수준을 평가하는 간단하고 효과적인 도구로서 활용될 수 있을 것이다.

The purpose of this study was to establish an association between the percent of energy from total sugar and disease prevalence of obesity, hypertension, dyslipidemia, insulin resistance, and metabolic syndrome with the context of the current population dietary practice in Korea. The Korean National Health and Nutrition Survey, 2001 and 2002 dataset were used as the source of data for this research. Usual nutritional intakes for over 20 years old people were calculated from the two non-consecutive dietary intake data from KNHANES 2001 and 2002 dataset. SAS and SUDAAN were used for statistical analyses. Sample weighted means, standard errors, and population percentages were calculated, and multiple logistic regression model with adjustment for covariates were used to determine the odds ratios(ORs) and 95% confidence intervals. Subjects were categorized as 3 ways and compared the LS means and ORs for heath factors. First, subjects excluding pregnant women, were categorized according to percent of energy from the usual total sugar intakes as ${\leq}10%$, 11-15%, 16-20%, 21-25%, >25%. Risk of LDL cholesterol showed a tendency to increase in the '>25%' group compared to the '<10%' group. The risks of the other health effects did not show any significant differences. Second, the subjects were categorized considering both Acceptable Macronutrient Distribution Range(AMDR) from carbohydrate and %Energy from total sugar as 'CHO<55% & Total sugar ${\leq}10%$', 'CHO 55-70% & Total sugar 11-25%', and '$CHO{\geq}70%$ & Total sugar ${\geq}25%$'. The risk of obesity tended to increase in the '$CHO{\geq}70%$ & Total sugar ${\geq}25%$' group compared to the 'CHO<55% & Total sugar ${\leq}10%$'. Third, the subjects were categorized as 'CHO<55% & Total sugar ${\leq}10%$', 'CHO 55-70% & Total sugar 11-20%', and '$CHO{\geq}70%$ & Total sugar ${\geq}20%$'. The risk of obesity also tended to increase in the '$CHO{\geq}70%$ & Total sugar ${\geq}20%$' group compared to the 'CHO<55% & Total sugar ${\geq}20%$' group. In conclusion, risk of LDL cholesterol showed a tendency to increase in the over 25% total sugar intake group, and the risk of obesity tended to increase in the 20-25% total sugar intake and high carbohydrate intake group. The risks of hypertension, hyperlipidemia, insulin resistance, and metabolic syndrome were not associated with total sugar intakes. More research to elucidate the association for Korean between the intakes of total sugar, added sugar, glucose, fructose, and sweeteners and diseases prevalences shoud be excuted in the future.
