Abstract

This study was conducted to determine if Mehrabian's eating-related characteristics questionnaire could be effectively applied in predicting obesity and eating disorders among Korean college students by examining the correlations between eating-related characteristics and anthropometry, nutrient intakes, psychological aspects of depression, and personality dimensions. The data were collected from 151 female students in classes of nutrition or psychology in Kyungnam University. Measurements of height, weight and triceps skinfold thickness (TSf) were made by well-trained interviewers, and BMI was calculated. Daily nutrient intakes were obtained from the self-reported three-day dietary records for the kinds and the amounts of foods consumed by the student subjects. The students were also asked to complete three questionnaires : Mehrabian's eating-related characteristics questionnaire, Eysenck Personality Questionnaire, and the Berk Depression Inventory. The results of the study were as follows : 1) Reliability of factored homogeneous item dimensions (FHIDS) of the translated version of the eating-related characteristics questionnaire showed a similar profile compared with the original. Moreover, the loading values of Cronbach-$\alpha$ for some FHIDs, which were excluded in order to constitute primary-level factors (for example, 'predisposition to obesity' etc) with a high reliability, were much lower than Mehrabian's. Therefore the eating-related characteristics questionnaire could be effectively used for Korean students for predicting predisposition to obesity and eating disorders. 2) With regard to the relationship between anthropometric indices and eating-related characteristics, BMI measurements showed a high and a positive correlation with 'predisposition to obesity' and 'uncontrollable urges to eat', and a negative correlation with a 'predisposition to anorexia'. The heavier body weight and the more fat mass that the subjects had, the higher the probability that the subjects were overeating. 3) The intakes of some minerals (Fe, K, Na) and Vitamin C showed significantly negative correlations with a 'predisposition to obesity' and a 'predisposition to anorexia'. But the intakes of vitamin B$_2$, niacin, and retinol were positively correlated with'uncontrollable urges to eat'. 4) Among personality dimensions, neuroticism had a positive correlation with a 'predisposition to obesity', 'uncontrollable urges to eat', and 'predisposition to anorexia'. 5) Neuroticism was negatively correlated with intakes of calories, carbohydrates, K, Fe, Vitamin C, etc. On the contrary, all personality dimensions were positively correlated with intakes of retinol. In conclusion, the translated version of Mehrabian's eating-related characteristics questionnaire appears to be effective for nutritional or psychological assessments of any predisposition to eating disorders among Korean college students.

본 연구의 결과를 요약하면 다음과 같다. 첫째, 본 연구에서 사용된 섭식특성 질문지는 일차수준 요인인 비만증 소인, 통제할 수 없는 섭식충동, 식욕상실증 소인을 구성하는 FHIBS의 신뢰도 (Cronbach-$\alpha$) 양상이 원래 Mehrabian의 것과 매우 유사하였다. 또한 신뢰성 높은 일차수준 요인을 구성하기 위해 제거된 FHIDs의 신뢰도 부하치는 더욱 낮은 값을 보였다. 따라서 우리나라 대학생들의 섭식장애 소인을 판정하기 위해 Mehrabian 일차 수준 요인과 동일하게 구성한 섭식특성 질문지의 번역판을 적용하는 데 문제가 없다고 판단되었다. 둘째, 체격지수와 섭식특성과의 상관에서는 BMI가 '비만증에 대한 소인'및 '조절되지 않는 섭식충동'과 높은 정적 상관 (p < .001)을, '식욕상실증 소인과'는 부적상관 (p <.05)을 보여서 체중이 무겁거나 체지방이 많을수록 과식이나 비만 가능성이 높은 것으로 나타났다. 세째. 영양소 섭취와 섭식특성과의 상관에서, '비만증에 대한 소인'과 '식욕상실에 대한 소인'이 높을수록 일부 무기질과 비타민의 섭취량이 적었던 반면, '조절되지 않는 섭식충동'이 높을 수록 레티놀을 비롯한 비타민 섭취량이 많은 경향을 보였다. 네째, 섭식특성과 우을 및 성격차원 간의 상관에서는, '신경증적 경향성'이 '비만증에 대한 소인' (p <.05), '조절되지 않는 섭식충동' (p < .001) 및 '우울수준' (p < .01)과 모두 정적 상관을 보였다. 마지막으로, 영양소 섭취량과 우울 및 성격차원의 관계에서는, '신경증적 경향성'의 성격 차원은 철분 섭취량과 유의적인 부적 상관 (p<.01)을 보이고 열량, 당질, 인, 칼륨 및 비타민 C 등과도 부적 상관 (p<.05)을 보여서 이러한 영양소의 섭취량이 적을수록 신경증적 경향성이 높은 것으로 나타났다. 특히 레티놀의 섭취가 높을수록 우울 수준을 비롯하여 신경증적 및 정신병적 경향이 높은 것으로 나타났다. 결론적으로 본 연구에서 사용된 섭식특성 질문지는 현재는 비만증이나 식욕상실증은 아니지만 그렇게 될 가능성이 있는 섭식장애 소인을 가진 영양학적, 심리학적으로 기여할 수 있을 것으로 사료된다. 따라서 Mehrabian의 일차수준 요인과 동일하게 구성한 섭식특성 질문지의 번역판을 섭식장애 소인을 판정하기 위해 우리나라 대학생들에게 적용하는데 문제가 없다고 판단되었다.
