Abstract

Muscularity-oriented disordered eating (MODE) is becoming increasingly common among women and is characterized by dietary alterations (e.g., blending meals into liquid form to increase caloric intake) aimed towards gaining lean muscle. In light of the mental health risks associated with these pathological eating behaviors, understanding factors that influence women’s engagement in MODE is essential for preventative efforts and for informing etiological models. Body image is a possible factor that may influence MODE in light of evidence of cross-sectional associations and its importance as a key risk factor for thinness-oriented disordered eating. However, research is yet to test for prospective relationships between the various components of body image (i.e., body dissatisfaction, body appreciation) and MODE, which was the aim of this study. Adult women completed the online study measures at baseline (Time 1 [T1]; n = 1760) and three-month follow-up (Time 2 [T2]; n = 1208). A series of univariate regressions revealed that all body image facets (i.e., preoccupation, overvaluation, dissatisfaction, body image appreciation and feeling fat) at T1 significantly predicted MODE at T2. However, multivariable models revealed that only preoccupation and body appreciation uniquely predicted MODE at T2, with a positive relationship observed for preoccupation and a negative one for body appreciation. This is the first study to establish temporal relationships between distinct body image facets and MODE. Pending replication, findings highlight possible targets for addressing MODE in women.

预测女性肌肉型饮食紊乱的身体形象特征:一项前瞻性研究的结果。
以肌肉为导向的饮食紊乱(MODE)在女性中越来越常见,其特点是改变饮食结构(如将饭菜混合成液体以增加热量摄入),目的是增加瘦肉。鉴于这些病态饮食行为所带来的心理健康风险,了解影响女性参与 MODE 的因素对于预防工作和为病因学模型提供信息至关重要。身体形象是影响 MODE 的一个可能因素,因为有证据表明身体形象与 MODE 存在横截面关联,而且身体形象是导致以瘦为导向的饮食紊乱的一个重要风险因素。然而,目前还没有研究对身体形象的各个组成部分(即身体不满意、身体欣赏)与 MODE 之间的前瞻性关系进行测试,而这正是本研究的目的所在。成年女性在基线时间(时间 1 [T1];人数 = 1760)和三个月的随访时间(时间 2 [T2];人数 = 1208)完成了在线研究测量。一系列单变量回归结果显示,在时间 1 的所有身体形象方面(即 "斤斤计较"、"高估"、"不满意"、"欣赏 "和 "感觉肥胖")都能显著预测时间 2 的 MODE。然而,多变量模型显示,只有 "先入为主 "和 "欣赏身体 "能独特地预测 T2 时的 MODE,其中 "先入为主 "与 MODE 呈正相关,而 "欣赏身体 "与 MODE 呈负相关。这是第一项在不同身体形象方面和 MODE 之间建立时间关系的研究。研究结果强调了解决女性 MODE 问题的可能目标,但尚待复制。

期刊介绍: Body Image is an international, peer-reviewed journal that publishes high-quality, scientific articles on body image and human physical appearance. Body Image is a multi-faceted concept that refers to persons perceptions and attitudes about their own body, particularly but not exclusively its appearance. The journal invites contributions from a broad range of disciplines-psychological science, other social and behavioral sciences, and medical and health sciences. The journal publishes original research articles, brief research reports, theoretical and review papers, and science-based practitioner reports of interest. Dissertation abstracts are also published online, and the journal gives an annual award for the best doctoral dissertation in this field.
