Brief 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.
