Relationship between circadian rhythm and severity of psoriasis and obesity

Abstract

The research aim is to identify the correlation between circadian rhythm in terms of changes in the chronotype of human working capacity and severity of psoriasis progression, obesity, and the disease impact on the quality of patients' life. Materials and Methods. The research focuses on the determination of the PASI, BMI, DIAG indexes and a patient's chronotype of working capacity. Results and Discussion. The results of the correlation analysis showed a very high negative correlation between chronotype of patients' working capacity and BMI. They also demonstrated a high negative correlation between PASI and DIAG indicators and chronotype of patients' working capacity. Conclusions. The circadian rhythm changes to the evening chronotype of human working capacity contribute to psoriasis worsening, weight gain, and negative impact of the disease on the quality of patients' life.
