This study investigates body weight perception and its influence on weight management behaviors in normal weight adolescents in Timis County, Romania. We hypothesized that misperception of overweight in normal weight adolescents would be positively associated with unhealthy weight control behaviors.
From 2908 respondents participating in the survey we selected a total of 2093 normal weight high school students for the analysis. Outcome measures included self-reported height and weight measurements, overweight misperceptions and weight control behaviors. Weighted prevalence estimates and odds ratios were computed.
There were 22.64% of normal weight students who perceived themselves as overweight. Females (36.48%) were more likely to perceive themselves as overweight than males (8.15%) (P < 0.0001). After adjusting for age and gender, students who perceived themselves as overweight were more likely to exercise (OR = 2.85; 95% CI: 2.25-3.61), eat less food, fewer calories or low fat foods (OR = 3.54; 95% CI: 2.78-4.51), fast for 24 hours or more (OR = 1.79; 95% CI: 1.28-2.49), take diet pills, powders or tea (OR = 3.93; 95% CI: 2.62-5.89), vomit or take laxatives (OR = 1.96; 95% CI: 1.15-3.34) to lose weight or to keep from gaining weight, compared to students who did not perceive themselves as overweight.
A significant proportion of normal weight high school students misperceive themselves as overweight and are engaging in unhealthy weight management behaviors. These results should be considered when establishing prevention programs and educational components that address weight misperceptions and the harmful effects of unhealthy weight control methods should be performed even among normal weight adolescents.
本研究旨在调查罗马尼亚蒂米什县正常体重青少年的体重感知及其对体重管理行为的影响。我们假设，正常体重青少年对超重的错误感知与不健康的体重控制行为呈正相关。
我们从参与调查的 2908 名受访者中选择了总共 2093 名正常体重的高中生进行分析。结果测量包括自我报告的身高和体重测量、超重错误感知和体重控制行为。计算了加权患病率估计和优势比。
有 22.64%的正常体重学生认为自己超重。女性（36.48%）比男性（8.15%）更有可能认为自己超重（P<0.0001）。在校正年龄和性别后，认为自己超重的学生更有可能进行锻炼（OR=2.85；95%CI：2.25-3.61）、少吃食物、少摄入卡路里或低脂肪食物（OR=3.54；95%CI：2.78-4.51）、禁食 24 小时或更长时间（OR=1.79；95%CI：1.28-2.49）、服用减肥药、粉末或茶（OR=3.93；95%CI：2.62-5.89）、呕吐或使用泻药（OR=1.96；95%CI：1.15-3.34）来减肥或防止体重增加，与不认为自己超重的学生相比。
相当一部分正常体重的高中生错误地认为自己超重，并采取了不健康的体重管理行为。在制定预防计划时应考虑到这些结果，即使在正常体重的青少年中，也应开展针对体重错误感知和不健康体重控制方法的有害影响的教育内容。
