Pruritic Symptoms Linked to Psychological StressStudy shows linear trend between increased psychological stress, higher symptom severity


FRIDAY, Dec. 25 (HealthDay News) -- In the general population, frequency of pruritic symptoms is strongly associated with psychological stress, according to a study in the December issue of the Archives of Dermatology.

Yosuke Yamamoto, M.D., of Kyoto University in Japan, and colleagues studied 2,224 adult participants (mean age, 44.6 years) in the 2003 Japan Health Diary Study who were free of psychiatric disorders. Of these, 70 participants (3.1 percent) presented with pruritic symptoms.

Compared to participants without pruritic symptoms, the researchers found that those with pruritic symptoms were significantly more likely to have higher psychological stress (β coefficient, 2.33). They also found that there was a linear trend between increased psychological stress and increased severity of pruritic symptoms (β coefficients, 0.81, 1.77, and 4.86 for the first, second, and third symptom tertiles, respectively).

"Additional investigations, including validations against other scales like visual analog scale, are now necessary to validate the use of health diaries in actual dermatological practice," the authors conclude.
