Abstract

The purpose of this study was to investigate the BMI, dietary behaviors, body satisfaction and factors affecting the weight control interest according to gender of middle school students (195 boys and 251 girls) in Wonju area. The average height and weight of the boys were $164.8{\pm}8.3\;cm$ and $55.5{\pm}12.3\;kg$ respectively. Those of the girls were $158.8{\pm}5.0\;cm$ and $48.7{\pm}7.4\;kg$ respectively. The average body mass index (BMI) of the boys and girls was 20.3 and 19.3 respectively. In both boys and girls, 69.7% of them had regular meals and the main reason for skipping meals was insufficient time to eat due to oversleeping (33.6%). Most of the subjects consumed snacks more than once a day (95.5%). The dietary intake attitude score of the girls ($35.08{\pm}5.91$) was higher than that of the boys ($33.81{\pm}5.45$) (p<0.01). The eating disorders score of the girls ($12.92{\pm}6.22$) was higher than that of the boys ($10.70{\pm}9.82$) (p<0.01). Also, 87.2% of the subjects showed normal behavior and 12.8% of the subjects had eating disorders, but there was no significant difference according to gender. The body satisfaction score of the boys ($30.16{\pm}5.08$) was higher than that of the girls ($28.00{\pm}5.52$) (p<0.001). In general, body satisfaction score correlated positively with dietary intake attitude score, but correlated negatively with eating disorders score (p<0.05). Multiple regression analysis revealed that body satisfaction score was the most significant variable which affected the weight control interest. Therefore, development of the nutrition education program for adolescents will be effective not only for the improvement of dietary behaviors but also for the positive change in the misleading perception about the ideal body shape.

본 연구는 원주지역 중학생 446명을 대상으로 성별에 따른 비만도, 식행동 및 신체만족도, 그리고 체중조절 관심도에 영향을 미치는 변인을 조사하였으며 그 결과는 다음과 같다. 남학생의 평균 신장과 체중은 각각 $164.8{\pm}8.3\;cm$$55.5{\pm}12.3\;kg$이었고, 여학생은 $158.8{\pm}5.0\;cm$$48.7{\pm}7.4\;kg$으로 나타났으며, 평균 BMI는 남학생과 여학생이 각각 20.3과 19.3으로 나타났다. 하루 식사 중 세 끼를 다 먹는 경우는 남녀학생 모두 69.7%로 나타났으며, 식사를 거르는 경우는 남녀학생 모두 아침결식율(43%)이 가장 높은 것으로 나타났다(p<0.01). 간식은 거의 대부분이 하루에 1번 이상 섭취(95.5%)하고 있었는데, 가공식품 구매 및 선택 시 영양표시를 읽는 지의 여부에 관해 '읽지 않는다'가 73.1%로 나타나 거의 대부분의 학생들이 영양표시를 읽지 않고 가공식품을 선택하는 것으로 나타났다(p<0.05). 식이섭취태도 전체점수는 여학생이 $35.08{\pm}5.91$점, 남학생이 $33.81{\pm}5.45$점으로 여학생이 남학생보다 높게 나타났는데(p<0.01), 이는 남학생이 여학생보다 고열량 및 지방이 많이 함유된 식품을 선호하였기 때문인 것으로 생각된다. 식이자기효능감의 전체점수는 여학생이 남학생보다 높게 나타났으나 유의적인 차이는 없었다. 식이장애증상 전체점수는 여학생이 남학생보다 높은 것으로 나타났으며(p<0.01), 조사대상자의 87.2%가 정상군으로, 12.8%가 식이장애가 있는 것으로 나타났으나 성별에 따른 유의적인 차이는 없었다. 그러나 남학생의 식이장애 위험군은 다른 연구에 비해 매우 높은 수준을 나타내었다. 신체만족도는 여학생이 $28.00{\pm}5.52$점, 남학생이 $30.16{\pm}5.08$점으로 여학생이 남학생보다 신체만족도가 낮은 것으로 나타났다(p<0.001). 각 변인들 간의 상호관련성을 알아본 결과, 식이자기효능감은 식이섭취태도와 양의 상관관계(r=0.398, p<0.01)를 나타내었으며, 신체만족도는 식이섭취태도와 양의 상관관계(r=0.117, p<0.05)를, 식이장애증상(r=-0.104, p<0.05)과는 음의 상관관계를 나타내었다. 또한 성별, BMI, 식이섭취태도 및 식이자기효능감, 식이장애증상 그리고 신체만족도와 같은 변인들이 체중조절 관심도에 미치는 영향을 알아보기 위하여 다중회귀분석을 실시한 결과, 여러 독립변인들은 체중조절 관심도를 33.3% 설명해 주고 있으며, 신체만족도($\beta=-0.387$, p<0.001)가 체중조절 관심도에 영향을 미치는 가장 중요한 변인으로 작용하였다. 이상의 결과에서 청소년들이 영양적으로 균형 잡힌 식사방법과 자신의 신체에 대한 올바른 인식을 형성할 수 있는 체계적인 영양교육 프로그램이 청소년들의 식행동 및 신체만족도를 높일 수 있도록 개발된다면 청소년들의 건강한 식사패턴과 이상체형에 대한 왜곡된 인식을 개선해 나가는데 큰 도움이 될 것으로 생각된다.
