来自纽约路透社健康讯：一项小规模研究显示，节食可能会导致一些肥胖儿童在体重和饮食方面出现不健康倾向。研究人员发现有一些肥胖青少年尝试节食而产生对减肥的偏见和贪食的习惯。
这些发表在《国际饮食失调》上的发现暗示节食对于一些超重儿童会导致“逆火”。研究对象包括10至16岁共80名肥胖儿童，主要询问他们节食史和对于减肥和饮食的态度。一半儿童承认他们有进食过多或贪食的习惯，即过度饮食缺乏控制。与节食之前相比，产生这些饮食失调问题多表现在这些儿童尝试节食后。但是对于这些有节食史的儿童，会出现对体重和饮食的认识上的偏见，很容易发生饮食失调。一般对于已经节食的贪食者，在出现贪食习惯之前往往节食。
参与研究的比利时根特大学的Caroline Braet博士认为，对于一些肥胖儿童，在超重、节食及不健康的饮食观念之间存在错误的途径。“家长将超重儿童进行节食可能是一种有害的事情。”
但是她强调说，这并不是意味着可以让肥胖儿童随意吃喝。最好的解决儿童肥胖问题的关键是规律和均衡的饮食、少吃快餐，进行有规律的体育运动，这些都比对儿童进行严格的节食要好。解决问题的目的是通过健康饮食来稳定肥胖儿童的体重。
Diets may spur unhealthy eating in some obese kids

NEW YORK (Reuters Health) - For some obese children, dieting may set off an unhealthy preoccupation with weight and eating, a small study suggests.
Researchers found that among obese adolescents, some of those who had tried dieting eventually developed a preoccupation with weight loss and a habit of binge-eating.
The findings, published in the International Journal of Eating Disorders, suggest that for some heavy children, dieting can backfire.
The study included 80 obese children between the ages of 10 and 16 who were interviewed about their history of dieting and attitudes toward weight loss and eating. Half of the children said they had a habit of overeating or bingeing, which refers to overeating with a feeling of being out of control.
Overall, children with such "disordered eating" problems were no more likely to have tried dieting than their peers were.
However, for those who did have a history of diet attempts, the dieting sometimes led to a preoccupation with weight and eating -- a potential precursor to eating disorders. Indeed, among binge-eaters who had dieted, the dieting typically came before the binge-eating problem.
This suggests that for some children, there's a "problematic pathway" from weight problems to dieting to unhealthy attitudes about food and weight, according to study co-author Dr. Caroline Braet of Ghent University in Belgium.
"Parents can do harmful things by putting their overweight children on a diet," Braet told Reuters Health.
However, that doesn't mean the alternative is to let obese children eat whatever they want, she stressed.
It's better to address children's weight problems with regular, balanced meals, limits on snacking and regular physical activity, according to Braet. Rather than trying to get kids to shed pounds with a restrictive diet, she explained, the goal should be to stabilize their weight with healthy eating.
