Several studies indicated that techniques to change body weight and appearance were prevalent and different among adolescents. The aim of the study, therefore, was to assess differences in frequency and type of body change techniques used among adolescents by sex and body weight status.
A sample of 758 adolescents aged 12-18 years were recruited from private and public schools in Tehran. Information about socio-demographic background and body change techniques were collected via a self-administered questionnaire.
A high percentage of adolescents used body change techniques frequently to alter their body appearance. Girls changed normal eating pattern significantly (p=0.007) to lose weight more frequently than boys while boys used this method significantly (p=0.01) to gain weight more frequently than girls. Overweight/obese adolescents exercised significantly to change muscle size (p=0.03) and changed normal diet to lose weight (p<0.001) more frequently than normal weight adolescents. The relation between sex and body weight status with body change techniques (p<0.0) implied that male and female adolescents especially overweight/obese adolescents were frequently trying to change their body appearance.
Significant differences existed in using body change techniques according to sex and body weight status and these should be considered in obesity prevention programs for adolescents.
多项研究表明，改变体重和外貌的方法在青少年中普遍存在且各不相同。因此，本研究旨在评估不同性别和体重状况的青少年在使用身体改变技术方面的频率和类型上的差异。
本研究从德黑兰的私立和公立学校招募了 758 名 12-18 岁的青少年作为样本。通过自填式问卷收集了有关社会人口背景和身体改变技术的信息。
大量青少年频繁使用身体改变技术来改变他们的身体外貌。与男孩相比，女孩为了减肥而改变正常的饮食习惯更为频繁（p=0.007），而男孩为了增肥而更频繁地使用这种方法（p=0.01）。超重/肥胖青少年更频繁地通过锻炼来改变肌肉大小（p=0.03），并通过改变正常饮食来减肥（p<0.001），比正常体重青少年更为频繁。性别和体重状况与身体改变技术之间的关系（p<0.0）表明，男性和女性青少年，尤其是超重/肥胖青少年，经常试图改变自己的身体外貌。
根据性别和体重状况，使用身体改变技术存在显著差异，在为青少年制定肥胖预防计划时应考虑到这些差异。
