This study was performed to investigate the validity of food photographs for estimating individuals' dietary intakes and compare it with other dietary assessment methods. Subjects were 7 professors, 2 researchers, 12 dietitian and 16 graduate students majoring in food and nutrition. Among the subjects, 20 subjects had research experiences in the dietary intake survey more than one year while 17 had not. Each subject estimated 50 food portions displayed in computer monitor by comparing with standard food photographs, which were weighed portions of 28 foods from typical Korean diet. No significant differences between the estimated value and the weighed value of 17 (34%) food portions were shown in research-experienced group and those of 14 (28%) food portions were shown in no-researchexperienced group. 24-hour recall was the most frequently-used method for dietary assessment followed by in the order of food frequency questionnaire, dietary record, diet history and weighing method. After estimating food portions by photographs, 30 subjects (81%) were willing to use the method for dietary assessment because of its convenience and easy communication between researcher and subject. This study suggests that digital photography method would be a useful and convenient new instrument for estimating individuals' dietary intake. However, it is necessary to create standard database for food portions and carry out systematic education for food estimation in order to apply this method in the fields.

Several self-administered dietary assessment questionnaires have recently been developed, validated, and used in nutritional epidemiological and clinical studies in Japan. This article describes recent evidence on development and validation of them. After extensive search of published articles both in English and Japanese languages, we identified 25 articles on 13 questionnaires of which validation studies have existed. Number of foods/menus assessed varied from 31 to 169 according to questionnaires. Eleven questionnaires were food frequency type, either with fixed portion size or semiquantitative, and two diet history types. All the 13 questionnaires were validated against intakes assessed with dietary record or 24-hour recall, and only two with biomarkers. Number of subjects used in the studies was between 23 and 350. All the studies used adult subjects. In the studies with dietary record or recall, the correlation coefficient for or orgy intake was between 0.22 and 0.65 (median = 0.44). Median correlation coefficient for nutrients was between 0.21 and 0.61. In the studies with biomarkers, serum marine-origin n-3 polyunsaturated fatty acids and carotenes, and urinary potassium seemed useful biomarkers. In conclusion, recent progress of this field in Japan is remarkable. But more research is needed for validation studies with biomarkers, and the development and validation of questionnaires for children and elderly subjects. (J Community Nutrition 5(2) : 83∼92,2003)

Literature suggests that iron deficiency anemia is prevalent among pregnant women all over the world. This study was designed to evaluate the iron status of pregnant women during the fist five months, with the intention of determining ways to reduce the prevalence of iron deficiency anemia among pregnant women in Korea. We collected dietary information and measured the biochemical status of iron in 171 pregnant women over 16 weeks of gestation (=16.7$\pm$2.34 week). Dietary intakes for 3 days were collected using the 24 hour recall and food record methods. The daily Fe intake was measured using the food frequency method. The Body Mass Index (BMI), calculated by using the pre-pregnancy weight and height, indicated that 31.3% of subjects were under-weight. We divided the subjects into normal and anemic group by using the serum ferritin levels. It appeared that the mean dietary intake of iron was 52.3% of the recommended level for pregnant women. The dietary quality evaluation showed that pregnant women ate only 58% of the recommended amount in the food groups of meat, fish, eggs, beans and milk and dairy products. The hematological indices showed that the mean Hemoglobin (Hb) was 11.9 g/dl, Hematocrit (Hct) was 35.1%, ferritin was 23.9 $ng/ml$, and transferrin was 297.3 ${\mu}g/dl$. The dietary intake of iron was significantly lower and the vitamin C intake was significantly higher in the anemic group. The pre-pregnancy BMI was significantly lower in the anemic group. Variables affecting iron intake were the Fe intake frequency index and the food group score. The Fe index showed significantly positive correlation with the pre-pregnancy food intake and the food group score. Hb showed a significantly positive correlation with the pre-pregnancy food intake. We concluded that strategies to improve iron status be implemented in the pre-pregnant stage so as to reduce the prevalence of iron deficiency and that we should stress on the importance of an adequate diet as well as the maintenance of a heathy weight.

Objectives: The objective of this study was to analyse the methods being used to control food intake and physical activity in RCTs of human obesity. Methods: A total of 21 randomized controlled trials (RCTs) were investigated. Nine of which were domestic studies from "http://oasis.kiom.re.kr" and the other of which were foreign studies from systematic reviews of RCTs on herbal medicine for treatment of human obesity. Results: According to domestic studies, "low calorie diet" were recommended in five cases of the domestic studies, "maintain current dietary habit" were recommended in two and no information on diet was two. Considering the seven cases where the information on diet was available, patients' food intake were checked at every visit in six cases. Only two cases among the six had been dropped owing to the violation of dietary habit by patients. Exercises were prohibited in two cases, "maintain current level of phisical activity" were recommended in three cases and, from the rest, no information was available. The level of physical activity were not strictly controlled by any means hence no drop out. According to foreign studies, "low calorie diet" were recommended in two cases, "very low calorie diet (less than 700 kcal/day)" in one case, "maintain current dietary habit" in two cases, "do not eat fat" in two cases and no information was available in the rest five cases. Exercises which concerns spending about 300 kcal/day was recommended in one case, "moderate exercise" were recommended in three cases, "maintain current level of physical activity" were recommended in three cases and no information available in the rest five cases. Conclusions: In order to improve the accuracy of RCT, for the dietary side, researchers should record patient food intake at every visit by means of 24-hour dietary recall methods. This can be supplemented by multiple choice survey that are designed to help patients to diagnose themselves more accurately leading to less bias. For the exercise side, it is highly recommended to confine the exercises to walking only so as to quantify the amount of physical activity more easily by using pedometer.

부산 및 경남 일부 지역의 남녀 초등학생 (4~6학년)과 중학생 (2~3학년)을 대상으로, 24시간 회상법과 식사기록법을 이용하여 수집한 식품섭취조사 내용을 분석하였고, 연령과 성별에 따른 네 군 (ME, FE, MM, FM)의 식행동과 영양소 섭취 실태가 주중과 주말에 유의한 차이가 있는 지 살펴보았다. 주요한 결과는 다음과 같다. 1) 부모와 함께 식사한 횟수, 혼자 저녁을 먹은 횟수, 친구와 외식한 횟수, 건강에 유익한 식품 및 건강에 유익하지 않은 식품의 섭취 수준, 간식구매 비용 등을 고려해볼 때 FE가 중학생 (MM, FM)에 비해 바람직한 식행동을 나타내었다. 2) 식품군별 섭취량은 주중에 비해 주말에 감소하는 경향을 보였으며 이러한 현상은 중학생에 비해 초등학생에서 더 뚜렷하였다. 특히 초등학생의 우유 및 유제품과 채소류의 주말 섭취량은 주중에 비해 현저히 감소하였다. 3) ME는 총에너지를 비롯한 대부분의 영양소 섭취량이 주말에 감소하였고, FE와 MM은 칼슘, 인, 아연, 나이아신, 비타민 $B_6$ 섭취량이 주말에 감소하였다. FM은 에너지 및 영양소 섭취 수준이 가장 낮았던 반면에 주중과 주말의 차이도 적었다. 4) MM이 초등학생 (ME, FE)에 비해 주중의 에너지, 단백질, 칼슘, 식이섬유, 아연, 비타민 A, 비타민 $B_1$, 나이아신, 비타민 $B_6$의 %KDRIs가 유의하게 낮았다. 또한 MM이 FE에 비하여 주말의 에너지, 칼슘, 아연, 비타민 $B_1$, 비타민 $B_2$, 나이아신, 비타민 $B_6$에 대한 %KDRIs가 유의하게 낮았다. 모든 군에서 칼슘의 섭취 부족이 심각한 것으로 나타났다. 6) 종합해보면 식행동과 식품 및 영양소 섭취에 있어 초등학생과 중학생의 연령과 성별에 따른 차이가 드러났으며 MM은 식행동과 식품 및 영양소 섭취가 가장 불량한 것으로 보인다. 따라서 초등학생과 중학생을 위한 영양교육 현장에서는 연령과 성별에 따른 식행동의 상이성, 주중과 주말의 차이 등을 고려함으로써 효과적인 영양중재가 가능할 것으로 사료된다.

The purpose of this study was to investigate the effects of smoking and/or alcohol drinking on the nutrient intake, nutritional status, and eating habits of adult males. The subjects were 157 male adults aged 20-49 living in Daejon. Interviews with questionaire on smoking and alcohol drinking habits and eating habits, anthropometric measurement, biochemical blood test, and dietary assessment by one-day 24 hour recall and two-day diet record were carried out. The subjects were divided into four groups : control (non-smoking and non-drinking), drinking only, smoking only, and the both(drinking and smoking). The average numbers of smoked cigarettes were 17.8/d and 19.1/d in the smoking only group and the both group, respectively. The frequency of alcohol drinking was 8.3 times/month and 11.6 times/month in the drinking only group and the both group, respectively. Height was significantly higher(P 0.05) in the drinking only group than in the none and smoking only groups, while the other anthropometric indices were not different among the four groups. There were positive correlations between smoking and drinking or coffee intake. Alcohol drinking increased eating-out frequency and the intakes of energy, protein, dietary fiber, vitamin A, B$_1$,$ B_6,$ Fe and P, while smoking decreased snack frequency and intakes of energy, protein and vitamin $ B_6,$. Blood pressure was not changed in the smoking only and drinking only groups compared to the none group, while systolic blood pressure was elevated in both group(P 0.05). Alcohol drinking significantly elevated(P 0.05) serum total cholesterol and LDL-cholestrol level, while smoking did not change the serum lipid and cholesterol levels. Hemoglobin nd MCHC levels were significantly elevated(P 0.05) by smoking. From these data, it is suggested that both smoking and drinking have influence on some eating habits and nutrient intakes, and especially alcohol drinking can induce hypercholesterolemia.
