摘要

Background

Evidence suggests that food insecurity (FI) is associated with body image concerns (e.g., muscle dysmorphia; MD), behavioral addictions, and disordered eating behaviors. This study aimed to investigate whether MD mediates the association between FI and risks of exercise addiction (EA) and muscularity-oriented eating (MOE), focusing on the moderating role of resilience.

Methods

A total of 1,500 young Taiwanese young adults (Mage = 22.2 years, 38.3% males) completed the online survey. Structural equation modeling was used to examine the relationships among the variables of interest. The significance of the moderated mediation model was assessed using bootstrapping.

Results

Results found that FI was indirectly associated with increased risks of EA (β = 0.431, [0.312, 0.563]) and MOE (β = 2.3, [1.707, 2.887]) through MD. A gender difference was noted, as FI was more strongly associated with the risk of MOE in males and EA in females. Furthermore, resilience moderated the meditation relationship linking FI to EA (index of moderated mediation = 0.066, [0.032, 0.105]) and MOE (index of moderated mediation = 0.341, [0.163, 0.528]).

Conclusions

FI is potentially associated with behavioral addiction and disordered eating psychopathology through body image concerns. Strengthening resilience may help attenuate these adverse effects in young adults with food security issues.
