Abstract

Objective

To compare food intake and eating behaviour in children and adolescents with obesity (OBE) undergoing weight loss intervention and normal weight (NW) in a real-life Snack Scenario.

Methods

Sixty OBE were examined before (T0) and after weight loss (T1) and compared to a single measurement comparison group of 27 NW. Participants watched a 20-min film and were encouraged to snack from a variety of foods ad libitum. Food intake was measured and eating behaviour assessed via a hidden camera and a validated questionnaire.

Results

The food and energy intake did not differ between NW (155 ± 83 g, 1067 ± 732 kJ) and OBE at T0 (144 ± 106 g, 1088 ± 883 kJ) but increased in OBE at T1 (187 ± 91 g, 1544 ± 845 kJ). Latency of food intake was significantly shorter in NW (0 m:07 s ± 0 m:08 s) compared to OBE (T0: 1 m:11 s ± 2 m:57 s). After weight loss, latency decreased in OBE (0 m:26 s ± 1 m:00 s). NW touched food more often (49 ± 24) than OBE (T0: 29 ± 23), but takes from plate were similar. The questionnaire revealed differences between OBE and NW, not correlating with Snack Scenario observations.

Conclusion

Eating behaviours differed in NW versus OBE at T0 but food intake was similar. Therefore, behaviour while eating may be an underestimated factor in the considerations for childhood obesity.

儿童肥胖症患者在真实零食场景中的食物摄入量和进食行为--使用隐藏摄像机进行的实验。

目的比较接受减肥干预的肥胖儿童和青少年（OBE）与正常体重儿童和青少年（NW）在真实零食场景中的食物摄入量和饮食行为：对 60 名减肥前（T0）和减肥后（T1）的肥胖儿童和青少年进行检查，并与 27 名正常体重儿童和青少年组成的单一测量对比组进行比较。参与者观看了一部 20 分钟的电影，并被鼓励自由选择各种食物作为零食。通过隐藏式摄像机和有效问卷对食物摄入量和饮食行为进行了测量和评估：在 T0（144 ± 106 g，1088 ± 883 kJ）时，NW（155 ± 83 g，1067 ± 732 kJ）和 OBE 的食物和能量摄入量没有差异，但在 T1（187 ± 91 g，1544 ± 845 kJ）时，OBE 的食物和能量摄入量有所增加。与 OBE（T0：1 m:11 s ± 2 m:57 s）相比，NW（0 m:07 s ± 0 m:08 s）的食物摄入潜伏期明显缩短。体重减轻后，OBE 的潜伏期缩短（0 m:26 s ± 1 m:00 s）。NW 接触食物的次数（49 ± 24）多于 OBE（T0：29 ± 23），但从盘中取食的次数相似。调查问卷显示，OBE 和 NW 之间存在差异，但与零食情景观察结果不相关：结论：在 T0 时，裸眼观察者与裸眼观察者的进食行为不同，但食物摄入量相似。因此，在考虑儿童肥胖问题时，进食行为可能是一个被低估的因素：临床试验注册：德国临床试验注册中心（DRKS），试验编号为 DRKS00005122。

期刊介绍： European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
