The purpose of the study was to examine the interrelationships among stress, eating behavior, and adiposity in a cohort of normal- and overweight individuals. Clinical markers of physiological stress (fasting serum cortisol) and adiposity (body mass index [BMI] and percent body fat) were obtained from participants selected for a natural history protocol ( n = 107). Self-reported data on eating behavior (using the Three-Factor Eating Questionnaire subscales such as Cognitive Restraint, Disinhibition, and Hunger) and psychological stress (via the Perceived Stress Scale) were evaluated. Demographic information was incorporated using principal component analysis, which revealed sex- and weight-based differences in stress, adiposity, and eating behavior measures. Following a cross-sectional and descriptive analysis, significant correlations were found between the Disinhibition and Hunger eating behavior subscales and measures of adiposity including BMI ( r = .30, p = .002 and r = .20, p = .036, respectively) and percent body fat ( r = .43, p = .000 and r = .22, p = .022, respectively). Relationships between stress measures and eating behavior were also evident in the analysis. Disinhibition and Hunger correlated positively with perceived stress ( r = .32, p .001 and r = .26, p = .008, respectively). However, Disinhibition varied inversely with serum cortisol levels ( r = -.25, p = .009). Future studies are warranted to better understand this paradox underlying the effects of perceived and physiological stress on eating behavior.
该研究的目的是在一组正常体重和超重个体中，检验压力、饮食行为和肥胖之间的相互关系。从入选自然史研究方案的参与者（n = 107）中获取生理压力（空腹血清皮质醇）和肥胖（体重指数[BMI]和体脂百分比）的临床指标。对饮食行为（使用三因素饮食问卷子量表，如认知抑制、去抑制和饥饿）和心理压力（通过感知压力量表）的自我报告数据进行评估。使用主成分分析纳入人口统计学信息，该分析揭示了压力、肥胖和饮食行为测量中基于性别和体重的差异。经过横断面和描述性分析，发现去抑制和饥饿饮食行为子量表与肥胖测量指标之间存在显著相关性，包括BMI（分别为r = 0.30，p = 0.002和r = 0.20，p = 0.036）和体脂百分比（分别为r = 0.43，p = 0.000和r = 0.22，p = 0.022）。在分析中，压力测量指标与饮食行为之间的关系也很明显。去抑制和饥饿与感知压力呈正相关（分别为r = 0.32，p < 0.001和r = 0.26，p = 0.008）。然而，去抑制与血清皮质醇水平呈负相关（r = -0.25，p = 0.009）。有必要进行进一步研究，以更好地理解感知压力和生理压力对饮食行为影响背后的这一矛盾现象。
