Abstract

This study was performed to investigate the food habits, eating behaviors, perception of body shape, statuses of body weight control by BMI (Body Mass Index) of 732 middle school students in Gwangju and Jeonnam. The results of this study were compared among under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the OW group, female students had low scores in eating at night only, while male students had low scores in eating at night, eating speed, and food selection. All subjects wanted more height than measured. Only male students in the UW group wanted weight loss, whereas female students in the OW and NW groups did. Higher BMI in female students resulted in more weight difference between measured and wanted. All subjects responded properly themselves in perception of body shape but the OW groups showed a big difference between their present weight and wanted weights. Higher BMI in all students corresponded to more interest in concern and experience of weight management. In the male students, the reason for weight management showed high tendency in being healthy, whereas the female students had high tendency in having a slender figure. Higher BMI in all students corresponded to bigger difference between wanted and perceived body shape. In contrast, lower BMI in all students meant more stress. Greater difference between wanted and measured weight and greater difference between wanted and perceived body shape corresponded to less satisfaction in body shape. In conclusion, compared to the NW and UW groups, the OW group had overeating habits highly linked to stress. Also the OW group didn't have desirable eating behaviors and attitudes because of their greater interest in concern and experience of weight control and stress accumulation, and finally there was difference in food habits and behaviors according to the BMI level. Therefore these results suggest that effective nutritional programs should be developed including correct body image and good dietary habits.

본 연구는 광주 전남지역 중학생 732명을 대상으로 BMI 수준에 따른 식습관, 식행동, 체형인식 및 체중조절 실태에대해 조사하였으며 이에 대한 연구 결과를 요약하면 다음과 같다. BMI 수준에 따른 조사대상자의 분포는 남학생이 저체중군 27.8%, 정상체중군 45.9%, 과체중군 26.3%이었으며, 여학생은 저체중군이 26.2%, 정상체중군 53.6%, 과체중군 20.2%이었다. 남녀 중학생의 평균 BMI는 각각 $20.7{\pm}1.0$과 $20.6{\pm}0.2$이었다. 점수로 평가한 식습관과 식행동에서 남자중학생은 과체중군이 저체중군에 비해 빨리 먹는 점수가 높으며, 저녁식사의 양과 야식섭취 및 식품선택 시 기호보다 영양을 고려하는 점수는 낮았다. 여자 중학생은 과체중군이 과식과 스트레스 시의 음식 섭취와 식품선택 시 가격보다 영양을 고려하는 점수는 높았고, 야식 점수가 낮았다. 조사대상자의 신장은 남자 중학생 저체중군이 정상체중군과 과체중군에 비해 유의적으로 낮았으나, 여자 중학생은 그룹간 차이가 없었으며, 남녀 중학생 모두 실측한 신장보다 더 크기를 원하였다. 조사대장자의 체중은 남녀 중학생 모두 그룹간의 차이가 유의적이었다. 남자 중학생은 과체중군에서만 체중감소를 희망한 반면, 여자 중학생은 과체중군뿐아니라 정상체중군에도 체중의 감소를 희망하였는데, BMI가 클수록 원하는 체중과 실측체중간의 차이가 컸다. 본 연구대상자들의 인지체형은 남녀 중학생 모두 해당 군별 체형에 근접하였으나, 정상체중군에서 인지체형에 대한 왜곡경향이 높았으며, 희망체형과 인지체형의 차이가 과체중군에서 가장 컸다. BMI가 높을수록 체중조절에 대한 관심과 경험이 높았는데, 남자 중학생은 건강을 위해서, 여자 중학생은 날씬한 외모를 갖고 싶어서가 체중감량의 이유로 가장 많았다. BMI가 클수록 체형만족도가 낮으며, 희망체형과 인지체형간의 차이 값이 컸으나 스트레스는 BMI가 낮을수록 컸다. 또한 희망체중과 체형에서 실측체중 및 인지체형을 뺀 값이 클수록 체형만족도가 낮았다. 본 연구의 결과, 과체중군은 정상체중군과 저체중군에 비해 과식, 스트레스 시의 음식섭취에서 보다 바람직하지 않았으며, 스트레스와 체중 조절관심도 및 경험이 더 많아, BMI 수준에 따라 식생활 양상에 차이를 보였는데, 과체중군의 식행동과 태도가 보다 바람직하지 못하였다. 따라서 남녀 중학생을 대상으로 올바른 체형인식과 더불어 체계적인 영양교육의 필요성을 제시하는 바이다.
