Eating behaviour traits of rigid control and disinhibition have been associated with body weight in both adults and adolescents. Moreover, adults reporting a dieting history have increased levels of unhealthy eating behaviours. Against this background, the present study aimed to examine the relationship between dieting history and eating behaviour traits in adolescents. For the purpose of this research, a total of sixty adolescents (aged 15 (sem 2·4) years) from the Québec Family Study completed the Three-Factor Eating Questionnaire (TFEQ) and a questionnaire regarding eating habits. Self-reported current and past dieting were analysed against eating behaviour traits measured by the TFEQ, including all subscales. As the results revealed, few adolescents reported currently dieting (n 3). Adolescents who reported a dieting history (23·3 %) were older (16·9 v. 14·4 years, P < 0·001), were more likely to be female (78·6 v. 41·3 %, P < 0·05) but did not have a significantly higher BMI z-score (1·5 v. 0·9, P = 0·10), although they were more likely to be either overweight or obese (P < 0·01). After correcting for sex, BMI and age, adolescents who reported a dieting history had higher levels of rigid control and disinhibition (P < 0·05-0·0001) than those reporting no dieting history. A greater proportion of adolescents characterised by high rigid control and high disinhibition were past dieters, compared to those characterised by low levels of both behaviour traits (53 v. 4 %). The study arrived at the following conclusions: as observed in adults, adolescents with a history of dieting present unfavourable eating behaviour traits. These behavioural traits may represent an additional challenge to the long-term regulation of body weight.
在成年人和青少年中，饮食行为特征中的严格控制和抑制不足与体重有关。此外，有节食史的成年人不健康的饮食行为水平更高。在此背景下，本研究旨在探讨青少年节食史与饮食行为特征之间的关系。为此，魁北克家庭研究中的 60 名青少年（年龄 15（学期 2·4）岁）完成了三因素饮食问卷（TFEQ）和一份关于饮食习惯的问卷。根据 TFEQ 测量的饮食行为特征，分析了自我报告的当前和过去的节食情况，包括所有子量表。结果显示，很少有青少年报告目前正在节食（n 3）。报告有节食史的青少年（23·3%）年龄较大（16·9 岁比 14·4 岁，P<0·001），更有可能是女性（78·6%比 41·3%，P<0·05），但 BMI z 评分（1·5 比 0·9，P=0·10）无显著升高，尽管他们更有可能超重或肥胖（P<0·01）。在校正性别、BMI 和年龄后，报告有节食史的青少年的严格控制和抑制程度较高（P<0·05-0·0001）。与低水平两种行为特征的青少年相比，高严格控制和高抑制的青少年中，有更多的是过去的节食者（53%比 4%）。研究得出以下结论：正如在成年人中观察到的那样，有节食史的青少年表现出不利的饮食行为特征。这些行为特征可能代表长期调节体重的额外挑战。
