This paper describes preliminary analysis of health-related social media postings in Twitter. We classified Tweets two ways: those (A) with and (B) without linked URLs, and similarly for users, those commonly posting Cat- egory A Tweets and users commonly posting Category B Tweets. The Tweet user groups and the two categories of Tweets show different characteristics in use of user-defined hash-tag terms, the impact of expanded URLs through so- cial media community, and posting period of the two Tweet categories. One us- er among the top 25 most frequent posters in each user group only posted both Category A and B Tweets. Seven hash-tag terms from the top 25 hash-tag terms obtained from each category were used for both Category A and B. Tweets with and without linked URLs show different characteristics in terms of user groups, hash-tag terms, and the posting period of the linked URLs.
