Psoriasis occurs equally among women and men, although the incidence is lower in darker-skinned races and ethnic groups. Psoriasis has a prevalence ranging from 0.2% to 4.8%. The exact etiology is unknown, but it is considered to be an autoimmune disease mediated by T lymphocytes. There is an association of HLA antigens seen in many psoriatic patients particularly in various racial and ethnic groups.
Option B: Psoriasis can present at any age. A bimodal age of onset has been recognized. The mean age of onset for the first presentation of psoriasis can range from 15 to 20 years of age, with a second peak occurring at 55 to 60 years.
Option C: A genetic predisposition has been recognized in some cases. Familial occurrence suggests its genetic predisposition. Psoriasis occurs worldwide, and its prevalence varies. In the United States, about 2% of the population is affected. High rates of psoriasis have been reported in the Faroe Islands. The prevalence of psoriasis is low in Japan and may be absent in Aboriginal Australians and Indians from South America.
Option D: Emotional distress, trauma, systemic illness, seasonal changes, and hormonal changes are linked to exacerbations. Generally, summer improves psoriasis while winter aggravates it. Apart from the above factors, infections, psychological stress, alcohol, smoking, obesity, and hypocalcemia are other triggering factors for psoriasis.
