The just-published 2011 edition of The Social Life of Health Information, from Pew Internet and the California HealthCare Foundation, shows that 27% of internet users go online to track weight or other health indicators online and 18% go online to find others with health concerns similar to their own–rising to 23% if one or more chronic conditions are present. There is also an increase in social networking–Facebook and other forums–as a source of health information and interacting with others. 15% of social network site users–7% of all adults–use social networking to get health information, up slightly from 11% in 2008. But 23% of social network users follow friends’ personal health experiences and 17% sadly use it to remember or memorialize others who suffered from a health condition.
**Update 13 May pm** Further riffing on the Pew/CHCF findings by Alex Howard at the O’Reilly Radar emerging tech blog: the rise of the ‘quantified self’ in the increase of sensor-based and online health data tracking, e-patients’ social networking and the new ‘digital divide’ between those with smartphones (younger, affluent) and those without (older) leaving those most in need of health information and services behind.
