BACKGROUND/OBJECTIVES: The purpose of this study was to develop a dish-based semiquantitative food frequency questionnaire (FFQ) for Korean adolescents and evaluate its reproducibility and validity. SUBJECTS/METHODS: Based on 24-hour dietary recall data from the 4th Korean National Health and Nutrition Examination Survey (KNHANES), we developed a FFQ with 71 items. From a quota sample of 160 adolescents recruited using gender and age group as stratification variables, 153 participated in the complete data collection process. The FFQ was administered to each subject twice, at an interval of 3-4 weeks, to evaluate the test-retest reliability. The validity of the FFQ was assessed relative to 8-day food record data. RESULTS: The study findings demonstrated the FFQ's satisfactory reproducibility. Spearman correlation coefficients ranged from 0.64(for ${\beta}-carotene$) to 0.81(for protein). From cross-classification analyses, the proportion of subjects in the same intake quartile was highest for protein (65.4%) and lowest for vitamin A(47.1%). With regard to validity analysis, Spearman correlation coefficients ranged from 0.27(for vitamin A and fiber) to 0.90 (for energy). The proportions of subjects in the opposite categories between the first FFQ and the 8-day food record data were generally low within the range from 0.74% (for energy and carbohydrate) to 13.2% (for ${\beta}-carotene$). CONCLUSIONS: In conclusion, the dish-based semiquantitative FFQ developed in this study can be useful for grouping Korean adolescents according to major macro- and micronutrient intakes with reasonable reproducibility and validity.

A survey was conducted to investigate the intake pattern of health supplements and health foods by using questionnaire. The data were collected from 395 adults over middle age and analyzed with SAS program. The natural foods were most frequently taken among health supplements and health foods for health. There was no difference in pattern of health supplements or health foods intake between male and female. The item taken over 20% of subjects was health drinks, green tea, ginseng product, dietary fiber drink, honey, general tea, tonic medicine from natural foods, vitamin B, vitamin C from nutrition supplements, and Lactobacillus product from health supplements. As the main reason for taking health supplements or health foods, the male indicated recovery of fatigue and improvement of health, but the female indicated recovery of fatigue and protection or treatment on disease(p<0.001). The frequency of taking health supplements or health foods was once a day. About the effect of health foods 70.1%, of subjects answered not bad and 25% responded very helpful for their health. Twenty percent of subjects experienced side effects such as diarrhea. The results showed that the proper education program should be developed for consumer to choose suitable health supplements or health foods according to their dietary life and health condition.

Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.

The purpose of this study was to compare the consciousness health status and food habit for farmers in Korea. Eight hundred persons were surveyed by rural leader of RDA, composed with 35.1% of male and 64.9% of female. Data collection includes height weight and blood pressure by measuring method and personal & family situation by interview for influential factor of health status and food habit. The questionnaire was included dietary habit of salt, sugar, dietary fiber and fat intake and other behavior questions related with diet. The subjects were composed 32.5% of elementary school graduated and 50% of middle size farming. Of the all subjects, 54% of were rice planted farming mainly and 19 were over 65 year-aged group. In the concept of disease prevalence. gender difference was exist, liver and heart complains were more frequency in male and waist pain and urinary complain in female, shoulder pain and nervousness were frequently prevalent to all group of farmers. The hypertension prevalence of farmers were 16% by measuring blood pressure, but consciousness of hypertension was very low (5%). The correlation of health status with personal factors were analysed, body weight, number of family, education level, and working level were significant with CMI score and Farmers' syndrome score. The food habit status was negatively correlated with weight and BMI, age was negatively correlated with CMI score and farmers' syndrome. The consciousness of health status and food habit score were significantly correlated with smoking and alcohol drinking. It concludes that good food habit contribute wellness of health. Nutrition education for better food habit would be helpful on health status.

We examined the association between eating frequency of rice vs. bread at breakfast and nutrient and food-group intake among 1771 female college students aged 18-20 years. The frequency of main staples at breakfast and the nutrient and food group intake for the previous month were assessed with a validated self-administered diet history questionnaire. We divided main staples into rice, bread, and noodles. As the eating frequency for noodles was almost negligible, we computed the difference of eating frequency of rice minus that of bread(mean = 0.7 times/week). Among 16 nutrients examined, the difference of eating frequency correlated significantly and negatively only with fat intake, especially saturated fatty acid (SFA) (r=-0.31, p<0.001), and significantly and positively with the intake of n-3 poly-unsaturated fatty acid, iron, sodium, protein, carotene, potassium, dietary fiber, and vitamin C (r=0.08-0.15, p<0.001) after adjusting for the energy intake, the residential area, the population size, and the living status with their families. In conclusion, the more frequent intake of rice compared to bread at breakfast correlated with the higher intake of the several vitamins and minerals, and the lower intake of fat, especially SFA. The only unfavorable aspect of the rice group was the higher sodium intake.

The objective of this study was to develop a semi-quantitative food frequency questionnaire (FFQ) for an adult population for use in the Korea National Health and Nutrition Examination Survey (KNHANES). The 24-hour recall data for 2,939 subjects aged 19 years and over from the fourth KNHANES first year (2007) were used to extract the items included in the questionnaire. The FFQ items were developed by selection of major dishes based on the cumulative contribution rate, between-person variability based on the cumulative R2 of energy and 14 nutrients (carbohydrate, protein, fat, crude fiber, calcium, phosphorous, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C) and the number of consumers of each dish. In addition, the FFQ items were revised with analysis of 24-hour recall data of the fourth KNHANES second and third year (2008, 2009). Finally, 112 items were included in the FFQ and grouped as follows: rice (5 items), noodles and dumplings (6), breads and rice cakes (8), soups and stews (12), soybeans, eggs, meat and fish (23), vegetables, seaweed and potatoes (27), milk and dairy products (4), fruits (13), beverages (5), snacks (6) and alcoholic beverages (3). The food items of FFQ accounted for an average of 87.0% of energy and 14 nutrient intakes and also accounted for 81.7% of the between-person variability. The frequency range of the FFQ items was classified into nine categories (never or seldom, once per month, 2-3 times per month, once per week, 2-4 times per week, 5-6 times per week, once per day, twice per day and three times per day) and the portion size was divided into three categories (small, medium and large). We expect that this developed dish-based FFQ could be used in assessment of longterm dietary intakes of Korean adults.

본 연구는 24시간회상법과 식품섭취빈도조사지를 이용하여 농촌지역 노인들의 영양소섭취량을 비교분석하였으며, 두 식이섭취조사방법 간의 상관성 및 타당성을 평가하였다. 조사대상자는 농촌지역 60세 이상 노인 168명(남자 89명, 여자 79명)이었으며 그 연구결과를 요약하면 다음과 같다. 조사대상자의 평균연령은 67세(남 69, 여 56)였으며, 평균 신장은 158 cm, 평균체중은 58.4 kg으로서, 본 연구의 농촌지역 남녀 노인의 평균 신장 및 체중은 한국인 $65{\sim}74$세의 평균체중 및 신장보다 낮았다. 24시간회상법과 식품섭취빈도조사법의 상관성 비교(Pearson's correlation)에서 남자노인의 식이섬유소 섭취량만이 p<0.01 수준에서 유의성을 나타내었으며, 나머지 영양소에서는 모두 낮은 상관계수를 나타내었다. 상관관계에서 비록 통계적 유의성을 보여주지는 못했지만 열량 및 대부분의 열량영양소들의 섭취량은 24시간회상법 및 식품섭취빈도조사법 모두에서 비슷한 수준으로 나타났다. 무기질(Ca, Na, K, P, Fe, Zn, Cu, Mn, Se) 및 비타민(비타민 A, thiamin, riboflavin, niacin 및 비타민 C) 섭취량에 대한 24시간회상법과 식품섭취빈도조사법의 상관성은 비록 유의적 상관성은 나타나지 않았으며, 대부분의 무기질 및 비타민 섭취랑은 24시간회상법 및 식품섭취빈도조사법 모두에서 비슷한 수준으로 나타났다. 따라서 두 식이섭취조사방법에 의한 특정 농촌지역 노인들의 무기질 및 비타민섭취량 측정은 타당성이 있는 것으로 간주된다. 24시간회상법과 식품섭취빈도조사법에 의한 각 영양소의 영양권장량(RDA) 및 영양기준치(NRV)에 대한 비교에서, 각 영양소의 섭취량은 두 식이조사방법 간에 큰 차이를 나타내지 않았다. 그러나 열량, 단백질, 지방 등의 대량영양소 및 대부분의 무기질, 비타민 모두에서 식품섭취빈도조사법에 의한 영양소 섭취율이 24시간회상법에 의한 섭취율보다 높게 나타났는데, 이는 식품섭취빈도조사법이 조사방법의 특성상 24시간 회상법에 의한 섭취율보다 높게 나올 수 있음을 입증하였다. 본 연구의 조사대상자인 농촌지역 노인인구 집단의 영양소섭취량 조사를 위해서는 24시간회상법 및 식이섭취조사법 모두를 사용함이 타당하다고 생각된다. 특히, 본 연구조사에서 여자노인의 경우는 남자노인에 비해 모든 영양소에서 식품섭취빈도조사법의 경우가 영양소섭취량이 더 높게 나타났으며, 이러한 현상은 동물성 영양소의 경우가 더 두드러졌다. 이는 농촌지역 여자노인들의 식물성 위주의 식품섭취가 예상되며 따라서 농촌여자노인의 영양상태가 남자노인들에 비해 상대적으로 더 불량할 것으로 예측된다. 24시간회상법과 식품섭취빈도조사법을 이용하여 농촌지역 노인들의 영양소섭취량을 측정하여 비교한 본 연구결과를 종합해보면, 비록 두 식이섭취조사방법 간에 높은 상관성은 보여주지 못하였지만, 영양소섭취량은 두 방법 간에 비슷한 수준을 보여주어, 본 연구대상 특정 농촌지역 노인들의 영양소섭취량 조사에 24시간회상법 및 식품섭취빈도조사법 모두가 사용될 수 있음을 예견하였다. 노인인구 대상으로 보다 정확한 영양소 섭취량 측정을 할 수 있는 식품섭취빈도조사지 개발이 시급한 요구로 제시된다.

본 연구는 제6기 2015년도 국민건강영양조사 자료를 활용하여 만 19-64세 한국 성인의 주요 식사 패턴을 도출한 후, 식사 패턴과 인슐린 저항성 간의 상관성을 분석하기 위해 수행되었다. 그 결과는 다음과 같다. 대상자의 식사 패턴을 요인분석 방법으로 분석한 결과, 'Healthy Korean meal pattern', 'Western meal pattern', 'White rice, alcohol, meat pattern'으로 나타났다. 'Healthy Korean meal pattern' 점수가 높을수록 연령이 높게 나타났으며, 식사 패턴에 따른 영양소 섭취량 분석 결과, 'Healthy Korean meal pattern' 섭취 점수가 높을수록 총 에너지, 탄수화물, 단백질, 비타민 A, 비타민 C, 칼슘, 인, 철, 칼륨, 식이섬유의 섭취가 유의하게 증가하였으며 'Western meal pattern' 섭취 점수가 높을수록 총 에너지, 단백질, 지방, 콜레스테롤의 섭취가 유의하게 증가하였고, 'White rice, alcohol, meat pattern' 점수가 높을수록 총 에너지와 나트륨의 섭취는 유의하게 증가하였고, 탄수화물, 비타민 C, 칼슘, 인, 칼륨, 식이섬유의 섭취는 유의하게 감소하였다. 식사 패턴에 따른 인슐린 저항성의 위험도를 분석한 결과 'Healthy Korean meal pattern'과 'Western meal pattern'은 인슐린 저항성과 유의한 연관성을 보이지 않았고, 'White rice, alcohol, meat pattern'은 인슐린 저항성의 위험도와 양의 연관성을 보였다. 이상의 결과로부터 'White rice, alcohol, meat pattern'의 식사를 많이 할수록 인슐린 저항성의 위험도가 높아지는 것을 알 수 있었다. 본 연구는 단면연구라는 제한점이 있으므로 향후 식사 패턴과 인슐린 저항성의 상관성을 확인할 수 있는 전향적 코호트 등의 연구가 필요하다.

The purpose of this study was to investigate the mutual relationship between food preference and nutrient intake status of high school students, based on the their personal characters which are sex, age, family type, number of family, mother's age, occupation, and school career. 439 students were selected with random stratified cluster sampling method. The study used a self-administrated questionnaire and 24-hour recall method for 5 days as instrument tools. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-Wallis test, ${x^2}-test$ by contingence table, and Spearman's correlation coefficient in non parametric statistical methods. Some of interesting results are as follows : 1. The correlation between sex and the set of characters of mother's age, school career and income is highly significant. However there is no any significant difference on the kinds of job and the types of family. 2. The relation between the preference of main dishes and the nutrient intake show a significant difference except to the noodles. This marks that preference of main dishes shows a direct proportion with the nutrient intakes except for the fat, vitamin A, vitamin C. 3. The preference of animal food marks a direct proportion with the nutrients such as energy, protein, fat, fiber, phosphorus, iron, vitamin $B_{1}$, vitamin $B_{2}$, and niacin 4. The preference of vegetable food gives some influence on the nutrient intake but the preference of soup is insignificant, the preference of Kimchi is in reverse proportion, and the preference of vegetable marks a direct proportion with the nutrient intake. 5. The preference of snacks marks a direct proportion with all kinds of nutrients intake except for the vitamin A, and vitamin C.
