Clinical Trial Summary

The influences of diet on psoriasis have been long discussed. As reported in previous publications, a majority of U.S. psoriasis population show high interest in the role of diet on their skin conditions. Given the distinct traditional perceptions and lifestyles in China, the dietary beliefs and behaviors in Chinese psoriasis patients would be very likely to show different patterns. Nevertheless, the information of this large population is still unknown. In this regard, the investigators conduct a questionnaire-based survey, aiming to assess the dietary perceptions and behaviors of Chinese psoriasis patients.

Description:

A total of 25 medical institutions all over China participated in the survey. Psoriasis patients surveyed were from both outpatient and inpatient dermatology departments. Researchers from each institution were trained for assisting patients to fill the questionnaire. Each participant filled the online-based questionnaire anonymously in a private setting. The questionnaire consisted of 54 main questions and extended questions, concerning the profile of disease conditions, perceptions and behaviors of diet in their daily life.
