Young adults with high body dissatisfaction may engage in disordered eating to reduce their weight, believing that weight loss will improve body satisfaction. Yet, limited research has examined whether suppressing weight contributes to improved body satisfaction in nonclinical samples. Undergraduate students (N = 661; 81.2% female) completed three surveys over a six-month period. Longitudinal mixed-effect models investigated whether weight suppression was associated with change in body dissatisfaction. Body dissatisfaction was higher on average among women, and greater weight suppression was associated with greater body dissatisfaction across genders. Among women, higher baseline weight suppression was related to higher body dissatisfaction across time; however, neither baseline weight suppression nor change in weight suppression were associated with change in body dissatisfaction. Among men, higher baseline weight suppression was related to increased body dissatisfaction over time. However, greater increases in weight suppression were associated with improvements in body dissatisfaction. Thus, the impact of weight suppression on body image outcomes may differ by gender. Findings suggest that when men become more weight suppressed, their body dissatisfaction decreases; however, changes in weight may not impact body dissatisfaction in women. Findings may inform educational programs challenging diet and weight loss myths, particularly for women.
对身材高度不满的年轻人可能会通过饮食失调来减轻体重，他们认为体重减轻会提高对身材的满意度。然而，仅有有限的研究探讨了在非临床样本中抑制体重是否有助于提高对身材的满意度。本科生（N = 661；81.2%为女性）在六个月的时间里完成了三项调查。纵向混合效应模型研究了抑制体重是否与身材不满的变化有关。女性的身材不满平均更高，而且在不同性别中，更大程度的体重抑制与更高的身材不满相关。在女性中，更高的基线体重抑制在不同时间都与更高的身材不满相关；然而，基线体重抑制和体重抑制的变化均与身材不满的变化无关。在男性中，更高的基线体重抑制与随时间增加的身材不满相关。然而，更大幅度的体重抑制增加与身材不满的改善相关。因此，体重抑制对身体形象结果的影响可能因性别而异。研究结果表明，当男性更多地抑制体重时，他们的身材不满会降低；然而，体重变化可能不会影响女性的身材不满。这些研究结果可能为挑战节食和减肥误区的教育项目提供参考，尤其是针对女性的项目。
