The assessment of the magnitude and associated factors of psoriasis

Background: Psoriasis is a chronic, inflammatory skin disorder resulting from a genetic predisposition combined with environmental triggers characterized by sharply demarcated erythematosus whitish scaly plaques. May be associated with psoriatic arthritis, metabolic syndrome, and other diseases. The prevalence is about 2% of the world’s population. Two peaks in the age of onset have been reported: Early-onset psoriasis at 20-30 years of age and Late-onset psoriasis at 50-60 years of age & equal in both sexes. Objectives: This study aimed to assess the magnitude and associated factors of psoriasis from October 2021 to June 2022 at Saint Paul’s Hospital Millennium Medical College Addis Ababa. Methods: A hospital-based cross-sectional prospective study was conducted from October 2021 to June 2022. A total sample size of 422 patients aged from 11 and above years was included in the study. Then using SPSS version 21.0 The data was entered and analyzed. Descriptive analysis was done to characterize the study participants. Bivariate and multivariable logistic regression was performed to determine the crude and independent predictors of the dependent variable. AOR with 95% CI was used to determine the independent predictors of psoriasis. Statistically, a significant association was considered at a p-value <0.05. Result: In this study, the magnitude of psoriasis was found to be 6.01% (95% CI:11.6,18.7). Moreover, in the multivariable logistic regression model educational status AOR (95% CI): =0.054, (0.01-0.30). And patients themselves AOR (95%CI): =34.90, (8.27-147.30) stress history were significant predictors of psoriasis. Conclusion: In this study 6.01% of patients were found to have psoriasis disease. Therefore, the finding needs to give great attention to strengthening national skin disease prevention and control services and implementation of public health policies on awareness, prevention, and treatment of psoriasis patients to keep care of skin and not neglect the disease contact health facility services.
