대전시에 거주하는 남ㆍ녀 고등학생의 체격지수 평가 및 섭식 장애 행동 분석

We investigated the prevalence of eating disorder risk group and its relationship with Physique status and eating behavior among high school students in Daejeon. In May - June 2002, 350 students were sampled from 6 high schools in Daejeon by multi-stage cluster sampling and assessed with self-completing questionnaires. We used the Korean version of Eating Attitude test(EAT-26) to screen eating disorder risk group. and other instruments to screen physique status and eating behavior. The response rate was 91%(total 320) and numbers of female students were 167(52.2%) and male students were 153(47.8%). Average age was 16.0${\pm}$0.35 years, and average body-mass index(BMI) and PIBW(Percent Ideal Body Weight) were 20.9${\pm}$3.3 Kg/m2 and 102${\pm}$4.2% in male students, 20.2${\pm}$3.7 Kg/m2 and 98${\pm}$7.2% in female students(p<0.0001). Over 50% of the subjects were dissatisfied with their body shape; the degree of dissatisfaction with body shape was higher in those who believed themselves to be fat. Mean score of EAT-26 was higher in female students (10.78${\pm}$7.36) than male students(6.07${\pm}$4.39)(p<0.0001). The prevalence of high risk eating disorder group was 2.6% in male students, 11.4% in female students(p<0.0001). Eating behavior was better in female students than male(p<0.0001). Eating behavior was significantly higher in eating disorder risk group in both sex. Therefore eating disorder symptomatology was highly prevalent among high school students in Daejeon. And this symptomatology has a more close relationship with physique status and eating behavior in female students.

본 연구는 대전시 소재 고둥학교를 대상으로 동일한 학년의 남학생과 여학생으로 분류하여 체형에 대한 주관적, 객관적 평가를 하고 섭식 장애 행동을 분석하여 섭식 장애 고위험집단을 분류해 내었다. 또한, 체형에 대한 만족도 및 체중조절 행동 및 식생활 행동을 분석하여 섭식장애 행동과의 상관성을 분석하였다. 연구 결과, 여학생들은 유의적으로 동일 연령의 남학생에 비해(p<0.05) 자신의 체형을 실제보다 더 비만한 쪽으로 생각하는 경향을 보였으며, 정상체중을 유지하고 있음에도 불구하고 과체중으로 인식하고 있었다. 섭식장애 고위험 집단으로 분류된 남학생과 여학생은 2.6%와 11.4%로 나타났으며, 전체 7.2%로 분류되었다. 섭식장애 행동에는 체형에 대한 만족도, 체중 조절 경험 그리고 식생활 행동이 영향을 미치는 변인으로 분석되었으며 이러한 경향은 여학생에게서 뚜렷하게 나타났다(p<0.001).
