Abstract

Usage of Vitamin D for the treatment of Psoriasis is on rise as it is relatively safe, cheap and easy to take with better results. Our primary hypothesis is that there is a strong correlation between vitamin D deficiency and Psoriasis and it is supported by small studies done abroad which show levels of Vitamin D are low in Psoriasis patient. To the best of my knowledge this will be the first study based on recent NHANES data set. We analyzed data in a populationbased study on Psoriatic patient population from US National Health and Nutrition Examination Survey, from 2009 -2010, Out of 10537, 191 psoriatic patients who are 20 years and older were identified based on the medical condition questionnaire and Vitamin eD levels in laboratory studies. We considered Vitamin D levels less than 50nmol/l as deficient. Data was missing on 16 patients. Out of 175 patients, 44 patients (25.14 %) have Vitamin D levels less than 50 nmol/l. Mexican Americans (42.85%) and Non-Hispanic black (46.15%) are more deficient than Non-Hispanic whites (19.65%). 58.14 % of Vitamin D deficient patients were obese when compared to 37.8 % without Vitamin D deficiency with p value of 0.0198 and Odds ratio of 2.2. Prevalence of Vitamin-D deficiency in Psoriatic patients is 25.14%. It is high in Mexican Americans and African Americans compared to Caucasians. Obesity is a risk factor for Vitamin D deficiency which doubles the risk among psoriasis patients. There is a marginal increased risk for Vitamin D deficiency in psoriasis patients in certain ethnic groups.
