Sleep, eating and psychopathologies: Which one(s) may be associated with the development of metabolic syndrome in psoriasis patients through psoriasis quality of life?

Background: Psoriasis (PS) has many comorbidities including metabolic-syndrome (MetS) sleep and eating disorders and psychopathologies. Objectives: Investigating the relationship between the presence of MetS and sleep, eating and psychological pathologies in PS-patients through psoriasis quality of life (PSQoL). Methods: In this cross-sectional and descriptive correlation study, besides demographics, MetS-parameters and comorbidities, PS-severity, PS related quality of life (PSQoL), sleep-quality (SQ), depression, anxiety, body image-related QoL (BIQoL), perceived stress, flourishing, social appearance anxiety and eating attitudes of subjects were examined with related scales. Data analyzed using SPSS software, according to two PS groups with and without MetS. Results: Of 107 PS-patients, 68 were diagnosed with MetS. Mean-age and PS-duration were significantly higher in MetS (+) group. PS- severity was correlated with poor PSQoL, anxiety, depression, impairing flourishing, poor overall SQ and impairing in two sleep-subcomponents in MetS (+) group, whereas it was correlated with only poor PSQoL and poor overal SQ in MetS (-) group. Poor PSQoL was correlated with anxiety, depression, poor BIQoL, poor overal SQ and impairing in three sleep-subcomponents in MetS (+) group, whereas no correlation was found between these parameters and PSQoL in MetS(-) group. Conclusions: MetS is seen at high-rate in patients with long-term PS. PS-severity is especially correlated with anxiety, impaired-flourishing, and impaired-SQ in PS-patients with Mets (+). PSQoL appear to be correlated with depression, anxiety, distorted-BI and impaired SQ in these patients. It should be kept in mind that neuropsychological factors may facilitate the development of dysmetabolic events in PS-patients, by impairing PSQoL.
