Abstract

Objectives: This study was performed to investigate the body image, food habits, nutrition knowledge, food intake frequency, nutrient intakes of female university students in Masan. Methods: Two groups (n = 302, nutrition major: 147, non-major: 155) were classified into underweight, normal weight and overweight/obesity groups according to BMI respectively. Results: Height and weight of all subjects were 161.5 cm, 53.2 kg and were 161.5 cm, 55.1 kg, 161.5 cm, 51.3 kg in major and non-major female students, respectively. The BMI and body weight were significantly different (p < 0.001). Significantly higher proportions of underweight students in both study groups had perceived as 'normal' or 'fat' (p < 0.001). Higher proportion of the subjects skipped breakfast and main reason was no time to eat. Nutrition knowledge score was significantly higher in major than in non-major subjects (p < 0.001). Fish intake frequency score was significantly higher in non-majors, while the vegetable intake frequency score was significantly higher in majors. Nutrient intakes were significantly higher the majors compared to non-majors, particularly the intake of calcium (p < 0.05), zinc (p < 0.001), vitamin C (p < 0.001) and vitamin E (p < 0.01). Subjects in both groups did not have adequate nutrient intakes compared to KDRIs. BMI showed a positive correlation with body image, body weight and nutrition knowledge score (p < 0.01). Conclusions: These results suggest that systematic nutrition education program which can be applied in real life is important for the formation of correct choices of food and good eating habits.

본 연구는 경남 마산에 위치한 경남대학교에 재학 중인 식품영양전공여대생(147명)과 비전공여대생(155명)의 BMI에 따른 차이가 있는지 분석하고 여대생들의 식품선택에 있어서 올바른 선택과 균형 잡힌 식습관의 정립을 위해 지속적이고 체계적인 영양교육을 하는데 기초자료를 제공하고자 신체계측, 신체이미지와 식습관, 식사섭취빈도, 영양지식, 영양소 섭취상태를 평가하였으며 결과를 요약하면 다음과 같다. 1. 전체 조사대상자의 신장과 체중은 각각 161.5 cm, 53.2 kg으로 조사되었고 전공여대생은 161.5 cm, 55.1 kg, 비전공여대생은 161.5 cm, 51.3 kg이었으며 체중은 유의한 차이를 보였다(p < 0.001). 2. 조사대상자 57.3%는 자신의 체형이 보통이다고 인식하였으며 37.7%는 뚱뚱하다고 인식하였다. 전공여대생 저체중군의 67.9%가 자신이 보통이다, 14.3%가 자신이 뚱뚱하다고 평가하였으며 정상 체중군에 속하면서 28%가 뚱뚱하다고 인식하였으며 과체중/비만군의 7.9%가 자신이 보통이라고 인식하는 것으로 조사되었고 비전공여대생은 저체중군의 59.2%가 자신이 보통이다, 20.4%가 자신이 뚱뚱하다, 정상체중군의 35.4%가 뚱뚱하다, 과체중/비만군의 20%가 자신이 보통이다고 인식하는 것으로 조사되었다. 식습관 중 평소 거르는 끼니에 대한 질문에서 전체 대상자의 77.2%가 아침을 거르며 평균 식사시간은 10분~20분 미만이 전체 대상자의 63.6%로 가장 많았으며 20분 이상은 전공여대생 과체중군이 높았으며 10분 미만은 비전공여대생 과체중군이 가장 높았다. 스트레스를 받은 후 선호하는 맛은 전공, 비전공여대생 모두 매운맛, 단맛 순으로 조사되었다. 3. 조사대상자의 영양지식점수를 보면 20점 만점에 전체 조사대상자 $16.2{\pm}2.4$, 전공여대생 $16.8{\pm}2.2$, 비전공여대생 $15.6{\pm}2.4$으로 유의한 차이(p < 0.001)를 보여 전공여대생이 비전공여대생에 비해 영양지식 수준이 높았으며 식품섭취빈도합계는 전체대상자 중 전공여대생이 비전공여대생에 비해 전체적으로 높았으나 유의한 차이는 없었다. 4. 조사대상자의 열량 및 영양소 섭취상태를 분석한 결과 나트륨, 비타민 B6, 콜레스테롤 이외 모든 영양소 섭취에서 전공여대생의 섭취가 높은 것으로 조사되었으며 칼슘(p < 0.05), 아연(p < 0.001), 비타민 C(p < 0.001), 비타민 E(p < 0.01)는 유의적으로 높았다. 섭취열량의 전체 평균은 $1208.9{\pm}435.0kcal$, 전공여대생이 $1234.0{\pm}436.7kcal$, 비전공여대생 $1185.2{\pm}433.5kcal$로 유의적이진 않지만 약간 높게 섭취하는 것으로 나타났다. BMI에 따른 유의적 차이는 없었으며 전공여대생은 저체중군 1342 kcal, 정상군 1183 kcal, 과체중/비만군 1261 kcal, 비전공여대생은 각각 1176 kcal, 1194 kcal, 1132 kcal로 조사되었다. 전공여대생 에너지비율은 당질 : 단백질 : 지질 = 57.6 : 16.6 : 28.2, 비전공여대생 당질 : 단백질 : 지질 = 57.8 : 17.7 : 27.5이었으며 특히 전공여대생 과체중/비만군이 당질 : 단백질 : 지방 = 58.9 : 14 : 28.4로 에너지 섭취에 대한 지방비율이 가장 높은 경향을 보였다. 식이섬유는 전공, 비전공여대생의 과체중/비만 군이 각각 10.2 g, 8.8 g으로 가장 낮게 섭취하였으며 칼슘은 전공, 비전공여대생 각각 310.6 mg, 265.6 mg으로 유의적인 차이를 보였으며 특히 비전공여대생 과체중/비만군 226.4 mg으로 낮았다. 인 섭취는 전공여대생 583.2 mg, 비전공여대생 545.8 mg, 철분은 각각 7.9 mg, 7.3 mg, 나트륨은 각각 2298.8 mg, 2461.6 mg으로 조사되었으며 두 그룹 모두 저체중군이 각각 2608.6 mg, 3032.8 mg으로 많이 섭취하였다. 아연은 전공여대생 5.9 mg, 비전공여대생 4.8 mg, 비타민 C는 각각 53.3 mg, 36.7 mg, 엽산은 각각 140 mg, 124 mg으로 조사되었으며 콜레스테롤 각각 208 mg, 211 mg으로 전공여대생 저체중군 254 mg, 비전공여대생 과체중/비만군이 260 mg으로 가장 높았다. 5. 조사대상자의 상관분석 결과 BMI와 유의한 양의 상관관계(p < 0.01)를 보인 것은 신체이미지, 영양지식점수, 체중이었다. 체중과 신체이미지, 영양지식점수(p < 0.01), 영양지식점수와 인스턴트섭취횟수(p < 0.05), 간식섭취횟수와 지질(p < 0.05), 당질과 지질(p < 0.01)도 양의 상관관계를 보였다. 이상의 결과를 종합해보면 전공, 비전공 여대생 모두 저체중이면서 자신이 보통이거나 뚱뚱하다고 인식하는 비율이 유의적으로 높았으며 전체적인 영양지식점수는 전공여대생이 비전공여대생에 비해 유의적으로 높았다. 이 결과는 비전공여대생에 비해 영양소 섭취량과 식품섭취빈도 결과가 양호한 편이었지만 우수한 편은 아니었으므로 영양지식을 알고 있는 것에 비해 식습관의 실천으로 잘 옮겨지지 않고 있는 문제점을 시사한다. 여대생들에게 식품선택에 있어서의 올바른 선택과 균형 잡힌 식습관의 정립을 위해 지속적이고 체계적인 영양교육 프로그램 개발과 교육이 중요하다고 사료된다.
