Abstract

Among current health-related issues, obesity is considered one of the foremost, and the importance of this subject has fostered a national interest in body weight loss. In this study, the differences in recognition of body weight loss according to age and gender are investigated. The subjects of the study were 720 (male: 360 and female: 360) aged between 10-60 years, who had experienced to try body weight loss during 6 months prior to this study. Anthropometrics, general characteristics, personal reasons for body weight loss, comprehension of body weight loss, and a knowledge of diet-related issues were assessed through a questionnaire. The anthropometric measurements showed significant differences in height, body weight (present and desired) and BMI (p < 0.05) by age and gender. The difference between desired body weight and actual body weight was greater for younger subjects or female, regardless of whether they had under- or normal body weight (p < 0.05). Reasons for body weight loss varied; younger subjects and female tended to lose body weight "to enhance their appearances", whereas the older subjects and male desired "to improve their health" (p < 0.05). Subjects had different concepts concerning body weight loss; younger subjects and female considered body weight loss as "maintenance of a slender figure, or becoming more lean". On the other hand, older subjects and male thought body weight loss to be "effects approaching normal body weight" (p < 0.05). From our studies, it can be concluded that attitude on concerning body weight loss varied according to a age and gender. Thus, consideration of this individual differences would be vital in developing contents of a particular nutritional education program for body weight loss.

본 연구는 체격, 체중감량 목표 및 개념, 지식정도 등의 체중감량에 대한 인식을 조사하기 위하여 수행되었다. 1) 조사대상자의 평균 연령은 남성 39.9세 여성 39.3세였고, 신장, 체중과 BMI는 연령과 성별에 따라 유의적인 차이 (p<0.05)를 나타내었다. 2) 비만도의 분포는 연령이 높고 남성의 경우 과체중과 비만이 유의적으로 많았다 (p<0.05). 3) 본 연구의 대상자들은 연령이 낮거나 여성의 경우 체중이 저체중이거나 정상체중임에도 불구하고 희망체중은 낮아 왜곡된 체형인식을 가지고 있었다. 4) 체중감량에 대한 목표는 연령이 낮을수록 외모적 이유로, 연령이 높을수록 건강상의 이유라고 대답하였다 (p<0.05). 체중감량 개념에 대해서는 연령이 낮을수록 "약간 마르거나 날씬한 몸매를 유지하는 것"이라고 인식한 반면, 연령이 높을수록 "정상 체중에 도달하기 위해 노력하는 것" 또는 "병에 걸리지 않도록 체중을 유지하는 것"이라고 대답하여 연령에 따른 유의적인 차이를 보여주었다 (p < 0.05). 5) 체중감량과 식습관, 운동 및 영양지식과 같은 체중감량에 관한 지식에 관한 연령과 성별에 따른 총 정답률의 유의적인 차이는 보이지 않았다. "물도 살을 찌게 한다"라는 문항은 68.5%의 가장 낮은 정답률을 보였으며, "아침식사를 거르는 것은 다이어트에 효과적이다"라는 문항에 91.7%의 가장 높은 정답률을 보였다. 본 연구 결과 성별, 연령별에 따라 체중감량에 대한 인식 목적 희망체중감량 목표 등에서 유의적인 차이가 나타났다. 따라서 체중감량을 위한 영양교육 자료 개발시 성별, 연령별로 특화된 맞춤형 영양교육 컨텐츠 개발이 필요하리라 사료된다.
