PubMed Health is a publicly-accessible online database that is a subcategory of the broader PubMed family. This specific section of PubMed focuses on current and past literature pertaining to the health sciences, with articles ranging in content from the latest in cancer treatment research to basic articles on remedying the common cold. As stated on the website, PubMed Health's mission is to "provide information for consumers and clinicians on prevention and treatment of diseases and conditions." Thus, the site is intended for both the layman and the professional, and houses both advanced and elementary literature pertaining to a broad scope of health concerns. There is an overarching focus on "clinical effectiveness research," meaning that PubMed Health has as a goal the presentation of content that relays and explicates that which has been scientifically proven to either prevent or identify particular diseases.

PubMed Health was created and is maintained by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM), which is the world's largest medical library, and "its electronic services delivers trillions of bytes of data to millions of users every day." The National Library of Medicine was founded in 1836, and the National Center for Biotechnology Information is a division of the library that "creates resources for researchers, particularly large-scale research in human genetics" (1). There is access to both condensed and full-length publications on the site.

For my purposes, I was searching specifically for the genetic context of obesity, which produced 77 articles, as seen in the screenshots to the left. Each article discussed obesity as it relates to being a factor in disease, with some articles being more genetically-focused than others.

Overall, PubMed Health is an easy-to-navigate, free-of-charge database that offers a variety of literature that can be digested by a readership of diverse abilities and scientific knowhow.
