The moderating role of gender in the association between latent psychosocial profiles and myopia severity among adolescents

Myopia is a critical public health issue; however, the roles of multidimensional psychological resources (i.e., resilience and emotion regulation) and potential gender differences remain underexplored. This cross-sectional study aimed to investigate the association between latent psychosocial profiles and myopia severity, and to examine the moderating role of gender in this association among adolescents. In total, 1008 Chinese seventh-grade students completed assessments of psychological resilience, emotion regulation, and depressive and anxiety symptoms. Myopia was measured as spherical equivalent refraction (SER). Latent profile analysis (LPA) was used to identify distinct psychological profiles, and moderation analysis tested gender's role in the profile-myopia association. LPA revealed three distinct psychosocial profiles: "Low-Resource", "Emotion-Driven", and "Balanced-Adaptive". The Low-Resource profile exhibited the highest levels of depression, anxiety, and myopia severity. A significant moderating effect of gender was found. Among females, both the Emotion-Driven and Balanced-Adaptive profiles were associated with significantly less myopia severity compared to the Low-Resource profile-an association not observed in males. Specific psychological resource profiles were linked to myopia severity, a relationship that was significantly moderated by gender and was prominent only in female adolescents. These findings highlight the importance of person-centered approaches and gender-specific considerations in understanding the psychosomatic pathways of myopia.
