Self-Esteem and Eating Attitudes in Emerging Adulthood: The Mediating Role of Social Physique Anxiety and the Moderating Role of Gender

Emerging adulthood is a critical time for the development of disordered eating attitudes. Low self-esteem is a known risk factor for unhealthy eating attitudes, but the mechanisms behind this link are not fully understood. This study examined the relationship between self-esteem and eating attitudes in emerging adults, focusing on the mediating role of social physique anxiety and the moderating role of gender. The sample included 495 university students (68.9% women, mean age = 20.94 years, SD = 1.97). Self-esteem, social physique anxiety, and eating attitudes were assessed using the Rosenberg Self-Esteem Scale, Social Physique Anxiety Scale, and Eating Attitudes Test-26, respectively. Mediation and moderation mediation analyses were conducted using PROCESS macro. Women reported lower self-esteem, higher levels of social physique anxiety, and more frequent disordered eating behaviors. Mediation analysis indicated that social physique anxiety fully mediated the relationship between self-esteem and eating attitudes (path c’: b = 0.05, 95% CI [−0.12, 0.21]; indirect effect: b = −0.44, 95% CI [−0.57, −0.32]). Moderated mediation revealed that the indirect effect of low self-esteem on maladaptive eating attitudes through social physique anxiety was stronger among women (index of moderated mediation: b = 0.28, 95% CI [0.07, 0.51]). These findings indicate that low self-esteem can heighten body-related distress in social settings, increasing vulnerability to disordered eating, especially among women. By providing a better understanding of the mechanisms linking self-esteem and eating attitudes in emerging adults, the findings can inform the development of interventions targeting self-perception and body-related concerns, especially among women, to reduce the risk of eating disorders and promote healthier eating attitudes.
