Risk Factors
Psoriasis affects both men and women of all ages although most people develop psoriasis as adults. The most significant risk factor for psoriasis is a family history of the condition. You are more likely to develop psoriasis if someone in your immediate family has it. As many as one third of the people with psoriasis may have a blood relative with the condition.
Environmental factors also are important. People who live in colder climates are more likely to develop psoriasis and often develop the condition earlier in life. Other factors that may influence your psoriasis risk include ethnicity. Psoriasis is less common in African-Americans and is rare in native ethnic groups from North and South America.
