Abstract

Assessing human exposure to food-borne hazards requires standardized assessment tools. The objective of this study was to validate a newly developed dietary assessment questionnaire to assess human exposure to food-borne hazards, which include dietary behavior and food consumption patterns such as eating frequency, types of food containers and cooking methods. A total of 216 adults were recruited for two questionnaire surveys (questionnaire 1 and 2) about 1 week apart with a 3 day diet record. Reproducibility was evaluated by comparing responses from questionnaires 1 and 2, and validity was checked by comparing responses from questionnaire 2 and the 3 day diet record. Comparisons were based on the percent agreement and Spearman's rank correlation coefficient. The mean exact agreement of food containers at purchase between questionnaires 1 and 2 was 73.5%, for storing containers it was 71.9%, and for cooking methods it was 83.0%. The mean correlation coefficient for food intake frequency between questionnaires 1 and 2 was 0.71 (range, 0.50-0.83). The mean correlation coefficient of the food intake frequency between questionnaire 2 and the 3 day diet record was 0.21 (range, 0.04-0.48). The exact and adjacent agreement of food intake frequency quartile assessed by questionnaire 2 and the 3 day diet record was 65.4% (range, 51.0-82.1%). Although the correlation coefficient for food intake frequency between questionnaire 2 and the 3 day diet record was low, the exact and adjacent food intake frequency agreement was higher than 50% and reproducibility of the dietary behaviors exceeded 70%. Therefore, the questionnaire developed in this study could be applied to assess diets for the human exposure to food-borne hazards as a qualitative assessment in a large population.

식품으로부터의 유해물질 노출 평가를 위해 개발한 식생활 조사지의 신뢰도와 타당도를 평가하고자 216명을 대상으로 식생활 조사를 2회 반복 실시하여 비교하였고, 3일 식사기록 결과와도 비교하였다. 1) 식품 구매 시 주로 사용하는 용기에 대해 동일한 응답을 한 비율은 전체 식품 평균 73.5%였다. 상대적으로 포장 용기가 다양하지 않은 식품에 대한 구매 용기 응답 일치도가 높게 나타났으며, 판매 시 다양한 포장 용기를 사용하는 식품에 대한 구매 용기 응답 일치도는 낮게 나타났다. 2) 식품 보관 시 주로 사용하는 용기에 대한 응답 일치도는 평균 71.9%였다. 가공된 식품을 구매하여 보관하는 식품에 대한 보관 용기 일치도가 높았으며, 조리 후 보관을 하는 식품에 대한 용기 일치도는 낮게 나타났다. 3) 주로 사용하는 조리방법에 대한 응답의 일치도는 평균 83.0%였다. 조리방법이 다양한 식품들에 대한 일치도가 낮게 나타났으며, 조리하지 않고 그대로 먹는 식품에 대한 일치도가 높게 나타났다. 4) 식품섭취빈도조사를 2회 실시하였을 때, 평균 상관계수가 0.71 (range: 0.50~0.83)이었고, 2차 식품섭취빈도조사와 식사기록법의 식품 섭취 횟수의 평균 상관계수는 0.21(range: 0.04~0.48)이었다. 5) 식품섭취빈도조사와 식사기록법으로 산출된 각 식품군별 식품 섭취 횟수를 사분위수로 나누었을 때 모든 식품군의 일치 및 근접 일치도의 합은 50% 이상이었다. 6) 본 연구에서 개발한 조사지는 식생활 항목의 신뢰도가 높고, 섭취빈도의 순위를 분류하는 타당도가 높으므로, 대규모 역학조사에서 질적인 노출수준 평가에 활용할 수 있을 것으로 사료된다.
