Background: There has been a rising interest in high carbohydrate and simple sugar intake in relation to NAFLD, obesity, and other metabolic risks. Due to practical constrains in a clinical setting, administration of a detailed dietary instrument is not always feasible. This study aimed to develop a brief FFQ for Korean adults` carbohydrate and simple sugar intake and evaluate its reproducibility and relative validity. Methods: The 2008-2010 Korean National Health and Nutrition Examination Survey provided a basis for the FFQ development. Specifically 24-hour dietary recall data from a total of 11,628 generally healthy adults aged 20-70 years and with reasonable calorie intake levels were used for selecting FFQ item. For carbohydrate FFQ items, contribution analysis and stepwise multivariate analysis identified important food or dish items contributing to absolute intake and inter-individual intake variance. With lack of simple sugar intake information in the KNHANES dietary data, simple sugar FFQ item selection process used a couple of semi-quantitative routes based on simple sugar-related food/dish codes, their intake frequency, and portion size information. Test-retest reproducibility was examined in a total of 108 generally healthy adults, and relative validity in reference to a 5-day diet diary was evaluated in 62 subjects. Results: Comparison of means, correlation analysis, and cross-tabulation analysis between first and second FFQ data revealed that the developed FFQ possess a reasonable reproducibility level for assessing carbohydrate and simple sugar intake. In comparison of FFQ and 5-day diet diary data, mean carbohydrate intakes were not different and a correlation coef- ficient for carbohydrate was high. Sugar food group consumption from the diet diary significantly increased from the lowest tertile to the highest tertile for simple sugar intake from the FFQ. Conclusions: The developed FFQ seems to have a reasonable reproducibility and relative validity for screening out those with high carbohydrate and simple sugar consumption.

We carried out a validation-calibration study of the food frequency questionnaire (FFQ) that we had previously developed for a community-based cohort of the Korean Genome and Health Study of the Korea National Genome Research Institute. We have collected a total of 254 3-day diet records (DRs) from 400 subjects, 200 each randomly selected from the two study cohorts of Ansung and Ansan. FFQ was administered at the time of cohort recruitment in 2001, and DRs were collected during a two month period from January through February of 2002. The mean age was 52.2 years. Farming for men and housewife for women were the most common occupations. The majority of the subjects had undergone 6∼12 years of education. The general characteristics including demographic and other data were not different from the total cohort subjects. Absolute levels of consumed nutrients including total energy (energy), protein, fat, carbohydrate, calcium, phosphorus, sodium, potassium, iron, retinol, carotene, vitamin A, thiamin, riboflavin, niacin and vitamin C were compared. The average of energy intake was not significantly different between the data collected by the 2 methods. However, consumptions of protein and fat were higher in data of DRs, whereas that of carbohydrate was higher in FFQ data. Significant correlation of each nutrient consumption between the data sets was observed (p < 0.05) except in the case of iron, while the average correlation coefficient between them was 0.22 ranging from 0.33 for energy to 0.11 for iron. The results of cross classification by quantile for exact classification ranged from 25.2% (carotene) to 35.0% (phosphorus), and from 64.6% (vitamin A) to 76.4% (retinol) for adjacent classification. The proportion of completely opposite classification was 8.1% in average. Calibration slope was estimated by regression and calibration parameters ranged from 0.025 for carotene to 0.423 for niacin. We conclude that the FFQ we have developed is an appropriate tool for assessing the nutrient intakes as ranking exposures in epidemiology studies in view that amounts of consumed nutrients obtained by FFQ were similar to those collected by DRs, that correlations between consumed nutrients collected by these methods were significant, and that classification results were relatively fair. The correlation coefficients, however, were lower than expected, which may be mainly due to the survey season. In fact, any short-term dietary survey cannot accurately reflect the overall dietary intakes that change heavily depending on seasons. Further studies including the analysis of chemical indices would be helpful for the studies of causal relationship between the diet and disease.

Validity and Reliability of a Dish-based, Semi-quantitative Food Frequency Questionnaire for Korean Diet and Cancer Research

Park, Min-Kyung,Noh, Hwa-Young,Song, Na-Yeun,Paik, Hee-Young,Park, So-Hee,Joung, Hyo-Jee,Song, Won-O,Kim, Jeong-Seon Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.2

This study evaluated the validity and reliability of applying a newly developed dish-based, semi-quantitative food frequency questionnaire (FFQ) for Korean diet and cancer research. The subjects in the present study were 288 Korean adults over 30 years of age who had completed two FFQs and four 3-day diet records (DRs) from May 2008 to February 2009. Student's t-tests, Chi-square tests, and Spearman's rank correlation coefficients were used to estimate and compare intakes from different dietary assessment tools. Agreement in quintiles was calculated to validate agreement between the results of the second FFQ (FFQ-2) conducted in February 2009 and the DRs. Median Spearman's correlation coefficients between the intake of nutrients and foods assessed by the FFQ-1 and FFQ-2 were 0.59 and 0.57, respectively, and the coefficients between the intake of nutrients and foods assessed by the FFQ-2 and the DRs were 0.31 and 0.29, respectively. The quintile classifications of same or adjacent quintile for intake of nutrients and foods were 64% and 65%, respectively. Misclassification into opposite quintiles occurred in less than 5% for all dietary factors. Thus this newly-developed, Korean dish-based FFQ demonstrated moderate correspondence with the four 3-day DRs. Its reliability and validity are comparable to those reported in other studies.

The aim of this study was to develop and evaluate the simple semi-quantitative food frequency questionnaire (FFQ) for assessing folate intake in women of reproductive age. We developed a 30-item FFQ, and tested the reliability and validity in 97 women aged between 20 and 39 yrs using the FFQs and 24-h recalls, which were carried out twice, respectively. Assessing the reliability, the correlation coefficients were 0.53 (Spearman`s) and 0.49 (Pearson`s) for folate. There was no significant difference of folate intake between FFQ1 and FFQ2. 36.1% subjects were classified into the same quartile and 83.5% into the same or adjacent quartile divided by folate intake. On determining the validity, the mean folate intake obtained from the FFQ (FFQ1) and 24h-recalls (2-d) were 306.6 ± 167.2 μg/d and 326.9 ± 103.3 μg/d, respectively. There was no significant difference between folate intakes from the two methods. The correlation coefficients for folate were 0.24 (Spearman`s) and 0.26 (Pearson`s). 39.2% of the subjects were categorized into the same quartile and 70.1% were into the same or adjacent quartile. In addition, sensitivity (64.3%) and specificity (62.3%) were estimated to evaluate the adequacy of folate intake. These results suggest that this FFQ would be a useful and a valuable instrument to assess the intake of folate among the Korean women of child-bearing age.

Jinhee Yum,Seungmin Lee 대한지역사회영양학회 2016 Nutrition Research and Practice Vol.10 No.4

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 β-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 β-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.

임경숙,박혜순,이태영 대한지역사회영양학회 2003 대한지역사회영양학회지 Vol.8 No.2

The purpose of this study was to develop and evaluate the validity of a food frequency questionnaire for Korean adolescents (FFQ-A) which could be used in clinical and epidemiological studies of the lifestyle and health of young people. The FFQ-A was designed to reflect the eating pattern of Korean adolescents, and was based on the 1998 Korean National Health and Nutrition Survey Reports. The FFQ-A had 25 food categories. A total of 125 subjects (aged 13 to 15 years) was recruited from a randomly chosen middle school in a middle-income neighborhood in Anyang, South Korea. Each subject completed a FFQ-A, as well as a three-day dietary record. Data from 117 subjects (boys 47, girls 70) was used in the final analyses. Data on the nutrients was analyzed to estimate the Pearson correlations, Spearman rank-order correlations and agreement with categories. The validity of the FFQ-A was assessed relative to a three-day dietary record. The Pearson correlation coefficients for all the subjects were 0.94, 0.87, 0.77, 0.79, 0.49 and 0.68 for energy, carbohydrate, protein, fat, calcium, and iron, respectively. Similarly the Spearman rank-order correlation coefficients were 0.94, 0.85, 0.79, 0.81, 0.46, and 0.77 for energy, carbohydrate, protein, fat, calcium and iron, respectively. The Kappa values for energy, carbohydrate, protein, fat, calcium, and iron were 0.88, 0.67, 0.63, 0.67, 0.26, and 0.59, respectively. The percentage for misclassification of the lowest quartile into the highest quartile or vice versa ranged from 0% (energy, carbohydrate, or fat) to 16.7% (Vitamin C). Therefore the FFQ-A has a reasonable ability to assess the energy, carbohydrate, protein and fat intakes as estimated from a three-day dietary record of Korean adolescents.

김정현(Jung-Hyun Kim),김오연(Oh Yoen Kim),이민준(Min June Lee),박은주(Eunju Park) 한국영양학회 2021 Journal of Nutrition and Health Vol.54 No.1

본 연구는 결혼으로 한국에 이주한 다문화여성의 영양상태를 파악할 수 있는 SQ-FFQ를 개발하고 이 조사지의 신뢰도와 타당도를 검증하기 위하여 실시하였다. 본 연구에서 개발된 SQ-FFQ는 결혼이주여성 대상 선행 연구, 국민건강영양조사의 SQ-FFQ 및 국민건강영양조사 결과를 고려하여 다소비, 다빈도 식품목록과 영양소별 섭취량에 대한 기여도가 높은 급원식품들을 고려하여 41개의 식품항목으로 선정하였다. 1회 섭취 분량은 0.5인분, 1인분, 1.5인분의 3개의 구간으로 나누었고 섭취빈도는 지난 1년 동안 평균적으로 얼마나 자주 먹었는지를 10개의 구간으로 분류한 SQ-FFQ를 개발하였다. 개발한 조사지의 재현성 및 타당도를 평가하기 위하여 서울과 대전 일부 지역의 건강가정·다문화가족지원센터를 방문한 35명의 결혼이주여성을 대상으로 SQ-FFQ (2회) 및 3일 식사 기록지를 조사한 후 1, 2차 반정량 식품섭취빈도 간의 영양소 섭취량 차이 및 SQ-FFQ와 3일 식사기록 간의 영양소 섭취량의 차이를 분석하였다. 1–2주간격으로 조사한 식품섭취빈도조사지의 재현성을 검토한 결과 에너지와 다량영양소 (탄수화물, 지방, 단백질)의 섭취량 간에는 유의적인 차이가 없었고, 비타민 A, 리보플라빈, 칼슘, 칼륨의 경우 1차 조사의 평균 섭취량보다 2차 조사의 평균 섭취량이 유의적으로 약간 높았다. 1차 및 2차 조사에서 도출된 동일 영양소 섭취량 간의 상관관계를 분석한 결과, 모든 동일 영양소 섭취량 간의 상관관계는 전반적으로 높은 상관관계를 보였다 (r = 0.453–0.885). 식품섭취빈도 조사와 3일 식사기록의 결과 비교를 통한 타당도 검증 결과, 식사기록법보다 식품섭취빈도 조사법에서 에너지, 탄수화물, 탄수화물, 비타민 C, 티아민, 엽산, 비타민B12, 칼슘, 나트륨의 섭취량이 유의적으로 높아 식품섭취빈도법이 식사기록법보다 다소 과대 추정되는 것을 알 수 있었다. 1차 식품섭취빈도조사와 식사기록법의 상관관계는 대부분의 영양소에서 유의적으로 나타났는데, 식물성 지방이 0.602로 가장 높았고, 총 섭취 에너지, 탄수화물, 지방, 티아민의 상관계수도 0.512–0.599로 다른 영양소들에 비해 상대적으로 높았다. 반면 비타민 A와 C, 칼슘, 철, 나트륨 등의 영양소에 대해서는 유의적인 상관관계를 보이지 않았다. 본 연구에서 결혼이주 다문화여성의 식생활 및 영양소 섭취실태를 파악하고자 개발된 자기기입식 SQ-FFQ는 신뢰성이 검증된 조사도구이며 에너지와 주요 영양소의 섭취 상태를 추정할 수 있는 도구로 사용하기에 적합한 것으로 사료된다. 그러나, 본 연구 결과는 최종 35명을 대상으로 분석하여 도출된 것으로 향후 대상자 수를 확대하여 적용해 볼 필요가 있다. 또한, 일부 영양소의 섭취 결과에 대한 타당성을 확보하기 위해서 조사식품 항목에 대한 조정을 고려해 보아야 할 것이며, 특히, 미량영양소의 경우 계절의 영향을 많이 받기 때문에 정성적인 조사를 병행하는 등의 보완이 필요하다. 또한 식품 및 영양소 섭취량 산출을 위한 분석 데이터베이스 구성을 위한 근거자료들이 더 확보되어야 할 것이다. Purpose: This study was implemented to develop and validate a semi-quantitative food frequency questionnaire (SQ-FFQ) to assess the dietary intake of married migrant women in multicultural families. Methods: The SQ-FFQ consisting of 41 food items was selected based on the information of frequently consumed foods from the preliminary studies on dietary intake survey for married migrant women or a Korean Health and Nutrition Examination survey. Thirty-five subjects who visited the Multicultural Family Support Center in Seoul and Daejeon area completed their three-day diet records and SQ-FFQ 2 times. The reproducibility and relative validity of SQ-FFQ were assessed by comparing the 1st and 2nd SQ-FFQ and by comparison with the three-day diet records, respectively. Results: The reliability of SQ-FFQ, which was examined 1–2 weeks apart, showed no significant difference in the energy and macronutrient intake (carbohydrate, fat, protein), while the average intakes of vitamin A, riboflavin, calcium, and potassium were slightly higher in the 2nd than 1st SQ-FFQ. All correlation coefficients for the reliability for nutrients were statistically significant, ranging from 0.453 to 0.885. The mean intakes of energy, carbohydrate, vitamin C, thiamin, folate, vitamin B12, calcium, and sodium obtained from the SQ-FFQ were greater than those of the 3-day dietary records. The Spearman"s correlation coefficient between the 2 methods was the highest for plant fat (r = 0.602; p < 0.001) and relatively higher for energy, carbohydrate, fat, and thiamin ranging from 0.512 to 0.599; and protein, riboflavin, niacin, folate ranging from 0.335 to 0.499, while no significant correlation was observed for vitamin A, C, calcium, iron, and sodium. Conclusion: The developed SQ-FFQ for married migrant women in multicultural families in this study appears to be useful for estimating the nutritional status, particularly energy, carbohydrates, fat, and vitamin B group.

Comparison of Validity of Food Group Intake by Food Frequency Questionnaire Between Pre- and Post-adjustment Estimates Derived from 2-day 24-hour Recalls in Combination with the Probability of Consumption

Kim, Dong-Woo,Oh, Se-Young,Kwon, Sung-Ok,Kim, Jeong-Seon Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.6

Validation of a food frequency questionnaire (FFQ) utilising a short-term measurement method is challenging when the reference method does not accurately reflect the usual food intake. In addition, food group intake that is not consumed on daily basis is more critical when episodically consumed foods are related and compared. To overcome these challenges, several statistical approaches have been developed to determine usual food intake distributions. The Multiple Source Method (MSM) can calculate the usual food intake by combining the frequency questions of an FFQ with the short-term food intake amount data. In this study, we applied the MSM to estimate the usual food group intake and evaluate the validity of an FFQ with a group of 333 Korean children (aged 3-6 y) who completed two 24-hour recalls (24HR) and one FFQ in 2010. After adjusting the data using the MSM procedure, the true rate of non-consumption for all food groups was less than 1% except for the beans group. The median Spearman correlation coefficients against FFQ of the mean of 2-d 24HRs data and the MSM-adjusted data were 0.20 (range: 0.11 to 0.40) and 0.35 (range: 0.14 to 0.60), respectively. The weighted kappa values against FFQ ranged from 0.08 to 0.25 for the mean of 2-d 24HRs data and from 0.10 to 0.41 for the MSM-adjusted data. For most food groups, the MSM-adjusted data showed relatively stronger correlations against FFQ than raw 2-d 24HRs data, from 0.03 (beverages) to 0.34 (mushrooms). The results of this study indicated that the application of the MSM, which was a better estimate of the usual intake, could be worth considering in FFQ validation studies among Korean children.

본 연구는 한국인의 영양상태를 파악할 수 있는 반정량 식품섭취빈도 조사지를 개발하고 이 조사지의 타당도를 검증하기 위하여 실시하였다. 본 연구에서 개발된 반정량 식품섭취빈도 조사지는 국민건강영양조사의 빈도가 높고 영양소별 섭취량에 대한 기여도가 높은 급원 식품을 참고하였고 비슷한 영양소별, 지방 함량, 조리 방법 등을 고려하여 88개의 식품항목으로 선정하였다. 1회 섭취 분량은 0.5인분, 1인분, 1.5인분의 3개의 구간으로 나누었고 섭취 빈도는 지난 1년 동안 평균적으로 얼마나 자주 먹었는지를 9개의 구간으로 분류한 반정량 식품섭취빈도 조사지를 개발하였다. 개발한 조사지의 타당도를 평가하기 위하여 건강검진을 목적으로 대학병원의 건강증진센터에 내원한 111명을 대상으로 반정량 식품섭취빈도 조사지와 3일 식사기록지를 동시에 조사한 후 두 조사방법에 의한 영양소 섭취량의 차이를 분석하였다. 그 결과 남녀 모두에서 식사기록법보다 식품섭취빈도 조사법에서 열량, 탄수화물, 단백질, 지방의 섭취량이 유의적으로 높아 식품섭취빈도법이 식사기록법보다 다소 과대 추정되는 것을 알 수 있었다. 두 조사방법에 의한 영양소 섭취량의 spearman 상관 계수를 보면 평균 0.402이었고, 포화지방산이 0.121로 가장 낮았고, 열량이 0.583으로 가장 높은 상관성을 보였다. 열량, 탄수화물, 단백질이 각각 0.583, 0.500, 0.466으로 다량영양소가 비교적 높은 상관성을 보였다. 또한 알코올도 0.527로 유의적인 높은 상관성을 보였다. 본 연구에서 개발된 반정량 식품섭취빈도 조사지는 지금까지 보고된 국내의 여러 연구에서 제시한 상관성의 범위를 크게 벗어나지 않았고 탄수화물, 단백질, 지방의 다량영양소와, 열량, 섬유소, 알코올, 그리고 칼슘, 인, 칼륨, 마그네슘, 아연 등 미네랄 등과 유의적인 상관관계를 보여 이러한 영양소와 관련 있는 만성질병과의 역학연구에 유용하게 사용 될 수 있을 것으로 사료된다. 그러나 상관관계가 낮게 보인 비타민과 지방산 종류의 섭취측정에는 어려움이 있다. Purpose: This study was implemented to develop and validate the semi-quantitative food frequency questionnaire (SQ-FFQ) to assess energy, carbohydrates, fat, protein, minerals, and vitamins as well as fatty acids and alcohol in Korean adults. Methods: The SQ-FFQ consisted of 88 food items, and 12 food groups were selected based on information of frequently consumed foods from the Korean Health and Nutrition Examination survey. Each portion size was categorized as one of three amounts: small (0.5 times), medium (1 time), and large (1.5 times). A total of 111 subjects finished 3-day diet records and the SQ-FFQ. The relative validity of SQ-FFQ was assessed by comparison with the 3-day diet records. Results: The mean nutrient intakes obtained from the SQ-FFQ were estimated to be greater than those of the two 3-day dietary records. Spearman’s correlation coefficient between the two methods was the highest for energy (r = 0.583; p < 0.001) and lowest for saturated fatty acid (r = 0.121). Correlation coefficients were energy (r = 0.583; p < 0.001), carbohydrates (r = 0.500; p < 0.001), protein (r = 0.466; p < 0.001), fat (r = 0.411; p < 0.001), dietary fiber (r = 0.467; p < 0.001), alcohol (r = 0.527; p < 0.001), calcium (r = 0.409; p < 0.001), phosphorus (r = 0.499; p < 0.001), potassium (r = 0.418; p < 0.001), magnesium (r = 0.427; p < 0.001), and zinc (r = 0.464; p < 0.001), respectively, for all subjects. Conclusion: The developed SQ-FFQ in this study seems to be useful for estimating nutritional status, particularly energy, carbohydrates, protein, fat, dietary fiber, alcohol, calcium, phosphorus, potassium, magnesium, and zinc of Korean adults.
