This study aimed to describe the frequency of dieting practices among adolescents and young adults in Canada, as well as determine the association between dieting and eating disorder attitudes and behaviors. Data from 2762 Canadian adolescents and young adults from the Canadian Study of Adolescent Health Behaviors were analyzed. Frequencies were used to determine the prevalence of 11 different diets among the sample, and chi-square tests were used to assess gender differences. Multiple modified Poisson and linear regression analyses were conducted to determine the associations between any dieting and eating disorder attitudes and behaviors. Among the sample, 15.7 % of girls and women, 10.4 % of boys and men, and 13.0 % of transgender/gender expansive (TGE) participants reported any dieting in the past 12 months, with the Ketogenic diet being most common among all genders. Results from regression analyses showed that engaging in any dieting in the past 12 months was associated with greater eating disorder psychopathology among girls, women, boys, and men, but not TGE participants. There were varying trends in association between specific types of dieting practices and eating disorder behaviors among girls, women, boys, and men. Dieting is relatively common among a national sample of Canadian adolescents and young adults, and engagement is associated with greater eating disorder psychopathology and behaviors. Healthcare and public health professionals should consider screening for eating disorders among adolescents and young adults who report engaging in dieting practices.
本研究旨在描述加拿大青少年和年轻人中节食行为的频率，并确定节食与饮食失调态度和行为之间的关系。对来自加拿大青少年健康行为研究的 2762 名加拿大青少年和年轻人的数据进行了分析。使用频率来确定样本中 11 种不同饮食的流行率，并使用卡方检验来评估性别差异。进行了多项修正泊松和线性回归分析，以确定任何节食与饮食失调态度和行为之间的关联。在样本中，15.7%的女孩和女性、10.4%的男孩和男性以及 13.0%的跨性别/性别扩展（TGE）参与者报告在过去 12 个月中有任何节食行为，其中生酮饮食在所有性别中最为常见。回归分析的结果表明，在过去 12 个月中进行任何节食与女孩、女性、男孩和男性的饮食失调心理病理学增加有关，但与 TGE 参与者无关。在女孩、女性、男孩和男性中，特定类型的节食行为与饮食失调行为之间的关联存在不同的趋势。节食在加拿大全国青少年和年轻人样本中较为普遍，参与节食与饮食失调心理病理学和行为增加有关。医疗保健和公共卫生专业人员应考虑在报告节食行为的青少年和年轻人中筛查饮食失调。
