Orthorexic eating behaviors can be conceptualized as a bidimensional construct encompassing an orthorexia nervosa dimension (ON) and a healthy orthorexia dimension (HO). Although variable-centered studies showed that ON and HO are distinguishable orthorexic eating behaviors, the evidence of whether they can co-occur or be distinct in subgroups of individuals is still limited. The present study aimed to address previous person-centered studies' limitations by examining profiles of ON and HO among a convenience sample of 251 French-speaking Canadian adults (85.7% women; M = 33.56). Profile membership was examined as function of participants characteristics such as age, gender, body mass index, frequency of physical activity and sports and vegetarianism. The relation between profile membership, intuitive eating and disordered eating attitudes and behaviors was also assessed. Latent profile analysis (LPA) were used to estimate profiles of ON and HO. Results from LPA did not provide support for the distinguishability of ON and HO. Indeed, they revealed the presence of two profiles showing co-occurring levels of ON and HO that only differed quantitatively: low (68.9% of the sample; low levels of ON and HO) or moderate orthorexic eating behaviors (31.1%; moderate levels of ON and HO). Participants who declared being vegetarian and being more frequently involved in physical activities and sports were more likely to belong to the moderate orthorexic eating behaviors' profile. Finally, participants from the moderate orthorexic eating behaviors' profile showed higher levels of disordered eating attitudes and behaviors, whereas those from the low orthorexic eating behaviors' profile showed higher levels of intuitive eating. Findings from the present study question the distinguishability of ON and HO dimensions. They also suggest that, similarly to ON, HO is also related to higher eating and lifestyle preoccupations.
健康饮食行为可以被概念化为一个包含两个维度的结构,包括一个饮食强迫症(ON)维度和一个健康饮食强迫症(HO)维度。尽管变量中心研究表明,ON 和 HO 是可区分的饮食强迫症行为,但关于它们是否可以在个体的亚组中同时存在或不同,证据仍然有限。本研究旨在通过检查 251 名讲法语的加拿大成年人(85.7%为女性;M=33.56)便利样本中的 ON 和 HO 概况,来解决之前的个体中心研究的局限性。检查了参与者特征(如年龄、性别、体重指数、身体活动和运动频率以及素食主义)与 ON 和 HO 概况成员身份的关系。还评估了概况成员身份、直觉饮食和饮食障碍态度和行为之间的关系。潜在剖面分析(LPA)用于估计 ON 和 HO 概况。LPA 的结果不支持 ON 和 HO 的可区分性。实际上,它们揭示了两种存在共同出现的 ON 和 HO 水平的概况:低(68.9%的样本;ON 和 HO 的低水平)或中等饮食强迫症行为(31.1%;ON 和 HO 的中等水平)。声称自己是素食主义者和更频繁地参与身体活动和运动的参与者更有可能属于中等饮食强迫症行为的概况。最后,中等饮食强迫症行为概况的参与者表现出更高水平的饮食障碍态度和行为,而低饮食强迫症行为概况的参与者表现出更高水平的直觉饮食。本研究的结果对 ON 和 HO 维度的可区分性提出了质疑。它们还表明,与 ON 相似,HO 也与更高的饮食和生活方式关注有关。
