[Objective] This paper identifies and analyzes the information needs of domestic and international question and answer health communities, aiming to find the patterns of regulation evolutions and explore the reasons. [Methods] First, we selected diabetes related data from ManYouBang and DailyStrength. Then, we compared topic evolution and co-occurrence, from the perspectives of theme and time, and using theme coding, social network and content analysis. [Results] The essential needs of HCQA users were “how to treat the disease”. For the chronic disease community, the “diet” theme was closely related to its co-occurrence themes. [Limitations] Our research did not examine the relevance of answers to questions, thus more in-depth study is needed on the topic evolution and content. [Conclusions] Domestic HCQA community is still developing while their foreign counterparts are stable. The former has only “question and answer attribute” while latter has both “Q&A” and “social” attributes.
