BACKGROUND/OBJECTIVES: Obesity is influenced by biological, hormonal, and social factors, contributing to chronic diseases and burdening the healthcare system. Chronic stress and emotional eating are linked to weight gain, affecting eating behaviors and metabolism. This study aimed to assess the association between stress, eating behavior, and adiposity in obese women.
This cross-sectional study included 132 obese women from Viçosa, Minas Gerais, Brazil. The participants completed the Lipp Stress Symptoms Inventory and the Dutch Eating Behavior Questionnaire. Blood samples were collected to measure plasma cortisol, and Body Mass Index (BMI) was calculated from weight and height measurements. Body fat was assessed using dual-energy X-ray absorptiometry (DXA). Associations between stress, eating behavior, and adiposity were evaluated using linear regression models, and interactions between stress and eating behavior subscales were tested.
Positive associations were observed between Phases I (alert), II (resistance), and III (exhaustion) of stress with emotional and external eating. A negative association was identified between dietary restraint and body fat, especially in women with lower cortisol levels (<13.7 mg/dL). Additionally, the alert phase was associated with higher android fat in these women.
The findings support the hypothesis that stress and eating behavior are associated with body adiposity and that stress is linked to emotional and external eating. An inverse association between restrained eating and body fat was observed in women with lower cortisol levels. These results highlight the importance of an interdisciplinary approach that incorporates emotional and stress conditions in obesity treatment.
背景/目的：肥胖受生物、激素和社会因素影响，会导致慢性病并给医疗系统带来负担。慢性应激和情绪化进食与体重增加有关，会影响饮食行为和新陈代谢。本研究旨在评估肥胖女性中应激、饮食行为与肥胖之间的关联。
这项横断面研究纳入了来自巴西米纳斯吉拉斯州维索萨的132名肥胖女性。参与者完成了利普应激症状量表和荷兰饮食行为问卷。采集血样以测量血浆皮质醇，并根据体重和身高测量值计算体重指数（BMI）。使用双能X线吸收法（DXA）评估体脂。使用线性回归模型评估应激、饮食行为与肥胖之间的关联，并测试应激与饮食行为子量表之间的相互作用。
在应激的第一阶段（警觉）、第二阶段（抵抗）和第三阶段（疲惫）与情绪化进食和外部进食之间观察到正相关。在饮食克制与体脂之间发现了负相关，尤其是在皮质醇水平较低（<13.7mg/dL）的女性中。此外，在这些女性中，警觉阶段与较高的腹部脂肪有关。
研究结果支持以下假设，即应激和饮食行为与身体肥胖有关，且应激与情绪化进食和外部进食有关。在皮质醇水平较低的女性中观察到饮食克制与体脂之间呈负相关。这些结果凸显了在肥胖治疗中采用综合情绪和应激状况的跨学科方法的重要性。
