这项研究调查了欧洲青少年膳食能量低报（UR）和高报（OV）的相关性。使用加速测量技术从来自八个欧洲国家的 1512 名 12.5-17.5 岁青少年中收集了两次自我管理的计算机化 24 小时饮食回忆和身体活动数据。获得身高和体重的客观测量值。 BMI 根据 Cole/国际肥胖工作组 (IOTF) 的分界点进行分类。通过自填问卷评估与饮食相关的态度。将报告的能量摄入量 (EI) 与预测的总能量消耗进行比较，以使用个人体力活动客观测量来确定 UR 和 OV。通过多级逻辑回归分析检查误报和协变量之间的关联。其中，考虑平均 EI 时，33.3% 的青少年为 UR，15.6% 为 OV。超重（OR 3.25；95% CI 2.01，5.27）和肥胖（OR 4.31；95% CI 1.92，9.65）青少年患 UR 的几率较高，而体重过轻的人更有可能过度报告（OR 1.67；95% CI 1.01，2.76）。对自己的身材感到满意（OR 0.61；95% CI 0.41，0.89）会降低 UR 的发病率，而经常不吃早餐（OR 2.14；95% CI 1.53，2.99）则与较高的 UR 发病率相关。那些担心体重增加的人（OR 0.55；95% CI 0.33，0.92）不太可能服用OV。体重状况和心理社会体重相关因素被发现是误报的主要相关因素。误报可能反映了社会理想的答案和报告自己饮食摄入量的能力较低，但也可能反映了为了减肥而真正的饮食不足，或者真正的暴饮暴食，以反映由于生长突增而导致的较高摄入量。应确定青少年中影响误报的因素，以澄清或更好地理解饮食与疾病的关联。
This study examined the correlates of dietary energy under-reporting (UR) and over-reporting (OV) in European adolescents. Two selfadministered computerised 24-h dietary recalls and physical activity data using accelerometry were collected from 1512 adolescents aged 12.5-17.5 years from eight European countries. Objective measurements of height and weight were obtained. BMI was categorised according to Cole/International Obesity Task Force (IOTF) cut-off points. Diet-related attitudes were assessed via self-administered questionnaires.Reported energy intake (EI) was compared with predicted total energy expenditure to identify UR and OV using individual physical activity objective measures. Associations between misreporting and covariates were examined by multilevel logistic regression analyses. Among all, 33.3% of the adolescents were UR and 15.6% were OV when considering mean EI. Overweight (OR 3.25; 95% CI 2.01, 5.27) and obese (OR 4.31; 95% CI 1.92, 9.65) adolescents had higher odds for UR, whereas underweight individuals were more likely to over-report (OR 1.67; 95% CI 1.01, 2.76). Being content with their own figures (OR 0.61; 95% CI 0.41, 0.89) decreased the odds for UR, whereas frequently skipping breakfast (OR 2.14; 95% CI 1.53, 2.99) was linked with higher odds for UR. Those being worried about gaining weight (OR 0.55; 95% CI 0.33, 0.92) were less likely to OV. Weight status and psychosocial weight-related factors were found to be the major correlates of misreporting. Misreporting may reflect socially desirable answers and low ability to report own dietary intakes, but also may reflect real under-eating in an attempt to lose weight or real over-eating to reflect higher intakes due to growth spurts. Factors influencing misreporting should be identified in youths to clarify or better understand diet-disease associations.
