Psychosocial aspects of obesity in adults with psoriasis: A systematic review.

The current evidence of the association between psychosocial factors and weight-related outcomes is largely cross-sectional with unclear directionality of causality. Longitudinal studies are needed to examine the replicability and generalisability of the examined obesity-related psychosocial factors in psoriasis. Theoretical exploration of subgroup differences and similarities may pave the way towards intervention personalisation, and ultimately, improved patient outcomes.
