This study aims to determine the factors affecting the tendency to lose weight (TLW) and its methods in Iranian children and adolescents.
In this cross-sectional nationwide study 14800 students, aged 7-18 years, living in 30 provinces of Iran were selected via multistage cluster random sampling method. The dietary and physical activity habits and TLW as well as psychosocial health status, anxiety, self-satisfaction, and change in dietary behaviors were assessed by the global school-based student health survey (WHO-GSHS) questionnaire. Multivariate logistic regression model was used to identify factors influencing TLW.
Overall, 14274 students (participation rate of 99%), consisting of 51% boys and 71.4% urban residents, completed the study. Of them, 37.7% (51.4% Girls and 48.6% boys) tended to lose weight. In multivariate model, the odds for TLW was 12% higher in students aged 13-18 years than those aged 6-12 years (OR = 1.12, 95% CI: 1.02 to 1.23; < 0.001). Students with high anxiety level were 43% more likely to have TLW (OR = 1.43, 95% CI: 1.28-1.59; < 0.001). The odds of increasing physical activity for weight loss was 22% lower in obese than in normal weight students (OR = 0.78, 95% CI: 0.66 to 0.93; < 0.001).
TLW was significantly higher in girls, as well as in those with higher anxiety level. In addition to dietary change, increasing physical activity should be encouraged among children and adolescents with excess weight. Public education regarding proper lifestyle change for reaching healthy weight should be underscored.
本研究旨在确定影响伊朗儿童和青少年减肥倾向（TLW）及其方法的因素。
在这项全国性横断面研究中，通过多阶段整群随机抽样方法，选取了伊朗30个省份的14800名7至18岁的学生。通过全球学校学生健康调查（WHO-GSHS）问卷评估饮食和身体活动习惯、TLW以及心理社会健康状况、焦虑、自我满意度和饮食行为变化。采用多变量逻辑回归模型确定影响TLW的因素。
总体而言，14274名学生（参与率99%）完成了研究，其中男生占51%，城市居民占71.4%。其中，37.7%（女孩占51.4%，男孩占48.6%）有减肥倾向。在多变量模型中，13至18岁的学生出现TLW的几率比6至12岁的学生高12%（OR = 1.12，95%CI：1.02至1.23；<0.001）。焦虑水平高的学生出现TLW的可能性可能性可能性比焦虑水平低的学生高43%（OR = 1.43，95%CI：1.28 - 1.59；<0.001）。肥胖学生通过增加身体活动来减肥的几率比正常体重学生低22%（OR = 0.78，95%CI：0.66至0.93；<0.001）。
女孩以及焦虑水平较高的人群中TLW明显更高。除了改变饮食外，应鼓励超重的儿童和青少年增加身体活动。应强调关于通过适当改变生活方式达到健康体重的公众教育。
