While psoriasis is a known risk factor for depression, depression can also exacerbate or trigger psoriasis. This relationship between depression and psoriasis, however, remains to be fully explored.
In an article published online on September 30 in JAMA Dermatology , Cohen et al examined the association between psoriasis and major depression in the US population. The authors conducted a population-based study that utilized individuals who were participating in the National Health and Nutrition Examination Survey from 2009 through 2012.
The authors identified 351 (2.8%) cases of psoriasis and 968 (7.8%) cases of major depression in the 12,382 participants included in the study. Of the patients with psoriasis, 58 (16.5%) met criteria for major depression. The mean (standard deviation) Patient Health Questionnaire-9 score was significantly higher among patients with a history of psoriasis than those without psoriasis (4.54 [5.7] vs 3.22 [4.3], P<.001). After adjustment for sex, age, race, body mass index, physical activity level, smoking history, alcohol use, history of myocardial infarction, history of stroke, and history of diabetes mellitus (odds ratio, 2.09 [95% confidence interval, 1.41–3.11], P<.001), psoriasis was significantly associated with major depression. Having a history of cardiovascular events did not modify the risk of major depression for patients with psoriasis. The investigators also found that the risk of major depression was not significantly different between patients with limited vs extensive psoriasis (odds ratio, 0.66 [95% confidence interval, 0.18–2.44], P=.53).
What’s the Issue?
We know that psoriasis is associated with depression. This study, however, has some surprising findings. The severity of psoriasis was unrelated to the risk of major depression. Additionally, cardiovascular events did not seem to impact major depression in participants with psoriasis. Therefore, all patients with psoriasis, regardless of severity, may be at risk for major depression. Will these findings impact your evaluation of psychological issues in individuals with psoriasis?
