Along with increased prevalence of obesity, body weight misperception has also increased among adolescents. This study aims to evaluate the proportion of weight misperception among Iranian children and adolescents and its association with some health-related factors.
Data were collected from 14,440 Iranian students, aged 7-18 years, who participated in the national school-based surveillance program (CASPIAN-V). The students' anthropometric indices and blood pressure were measured using standardized methods, and valid questionnaires were used to assess their weight perception, eating patterns, physical activity and sedentary behaviors. According to agreements between the real weight and self-perceived weight status, participants were classified as underestimated, accurate and overestimated weight.
The rates of underestimated, accurate and overestimated weight were 30.8%, 40.8% and 28.4%, respectively. In comparison with the accurate-weight group, both the underestimated- and overestimated-weight groups were less likely to have daily consumption of sugar-sweetened beverages (OR: 0.83, 95% CI: 0.74-0.93 and OR: 0.39, 95% CI: 0.34-0.44, respectively), sweets (OR: 0.81, 95% CI: 0.73-0.90 and OR: 0.68, 95% CI: 0.61-0.76, respectively) and salty snacks (OR: 0.78, 95% CI: 0.66-0.92 and OR: 0.30, 95% CI: 0.24-0.38, respectively). In the overestimated-weight group, the odds of daily intake of fast food decreased by 67% and the odds of low physical activity declined by 38% in comparison with the accurate-weight group.
Weight misperception had a high prevalence among Iranian children and adolescents and is associated with their dietary patterns and physical activity behaviors. Suitable education programs need to be developed to correct the children and adolescents' insight about their weight status.
随着肥胖患病率的上升，青少年对体重的错误认知也有所增加。本研究旨在评估伊朗儿童和青少年体重错误认知的比例及其与一些健康相关因素的关联。
数据收集自14440名7至18岁参与全国学校监测项目（CASPIAN-V）的伊朗学生。使用标准化方法测量学生的人体测量指标和血压，并使用有效问卷评估他们的体重认知、饮食模式、身体活动和久坐行为。根据实际体重与自我感知体重状况的一致性，参与者被分为体重低估、准确和高估组。
体重低估、准确和高估的发生率分别为30.8%、40.8%和28.4%。与体重准确组相比，体重低估组和高估组每天饮用含糖饮料的可能性均较低（比值比：分别为0.83，95%置信区间：0.74 - 0.93和0.39，95%置信区间：0.34 - 0.44），食用甜食的可能性较低（比值比：分别为0.81，95%置信区间：0.73 - 0.90和0.68，95%置信区间：0.61 - 0.76），以及食用咸味零食的可能性较低（比值比：分别为0.78，95%置信区间：0.66 - 0.92和0.30，95%置信区间：0.24 - 0.38）。与体重准确组相比，体重高估组每天摄入快餐的几率降低了67%，低身体活动的几率降低了38%。
体重错误认知在伊朗儿童和青少年中普遍存在，并且与他们的饮食模式和身体活动行为有关。需要制定适当的教育计划来纠正儿童和青少年对自身体重状况的认识。
