Food addiction is currently not an official diagnosis (as a standalone disorder substance-related and addictive disorder) in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). To best of our knowledge, there is no previous research on differences between addictive-like eating behavior regarding its associations with psychological distress, eating behaviors and physical activity among individuals with obesity. The objective of the present study was to distinguish psychological and behavioral patterns of individuals with obesity concerning food addiction using a cluster analysis. We determined the profiles of the participants in terms of psychological distress, eating behaviors and physical activity and evaluated their association with food addiction. A cross-sectional study was conducted between September and November 2020, during the lockdown period imposed by the government for the COVID-19 pandemic. A sample of 507 individuals with obesity aged between 18 and 65 years participated in the present study by filling in the online questionnaire, including the validated Arabic version of the modified version of the Yale Food Addiction Scale, the Arabic version of the Depression, Anxiety and Stress Scale, the Three-Factor Eating Questionnaire, and the short version of the International Physical Activity Questionnaire. A cluster analysis was performed using the K-mean method to identify and group participants according to their patterns/profiles. A stepwise linear regression was conducted, taking the food addiction score as the dependent variable. Higher levels of uncontrolled eating, emotional eating and stress were significantly associated with higher food addiction score. Belonging to cluster 2 (psychological well-being and cognitive restraint) (B = 14.49) or cluster 3 (moderate psychological distress and cognitive restraint) (B = 6.67) compared to cluster 1 (psychological well-being, appropriate physical activity levels and eating behaviors) was significantly associated with higher food addiction score. The present research revealed that food addiction is significantly associated with higher psychological distress and maladaptive eating behaviors. Higher levels of uncontrolled eating, emotional eating and stress as well as belonging to clusters 2 and 3 were found to be predictors of food addiction in individuals with obesity in the present study. This knowledge could be useful in regard to psychological treatment of obesity and addictive-like eating behavior.
食物成瘾目前在《精神疾病诊断与统计手册》第5版(DSM-5)中并非正式诊断(作为一种独立的与物质相关的成瘾性障碍)。据我们所知,此前尚无关于肥胖个体中类似成瘾的饮食行为在与心理困扰、饮食行为和身体活动的关联方面差异的研究。本研究的目的是通过聚类分析来区分肥胖个体中与食物成瘾相关的心理和行为模式。我们根据心理困扰、饮食行为和身体活动确定了参与者的特征,并评估了它们与食物成瘾的关联。在2020年9月至11月政府因新冠疫情实施封锁期间进行了一项横断面研究。507名年龄在18至65岁之间的肥胖个体通过填写在线问卷参与了本研究,问卷包括经过验证的耶鲁食物成瘾量表修订版的阿拉伯语版本、抑郁、焦虑和压力量表的阿拉伯语版本、三因素饮食问卷以及国际身体活动问卷简版。使用K均值法进行聚类分析,以根据参与者的模式/特征对其进行识别和分组。以食物成瘾得分作为因变量进行逐步线性回归。更高水平的无节制饮食、情绪化饮食和压力与更高的食物成瘾得分显著相关。与第1组(心理健康、适当的身体活动水平和饮食行为)相比,属于第2组(心理健康和认知克制)(B = 14.49)或第3组(中度心理困扰和认知克制)(B = 6.67)与更高的食物成瘾得分显著相关。本研究表明食物成瘾与更高水平的心理困扰和适应不良的饮食行为显著相关。在本研究中,更高水平的无节制饮食、情绪化饮食和压力以及属于第2组和第3组被发现是肥胖个体食物成瘾的预测因素。这些知识可能对肥胖和类似成瘾性饮食行为的心理治疗有用。
