Happier Tweets, Healthier Communities
Why does one community have higher levels of heart disease than another? Some of the reasons are obvious, such as income and education levels or local eating and exercise norms.
But as epidemiologists have long argued, other likely factors are more ephemeral. Among them: how angry or content the residents tend to feel, and whether the environment fosters a sense of social connectedness.
Measuring such things is tough, but newly published research reports telling indicators can be found in bursts of 140 characters or less. Examining data on a county-by-county basis, it finds a strong connection between two seemingly disparate factors: deaths caused by the narrowing and hardening of coronary arteries and the language residents use on their Twitter accounts.
Social media can be a very useful research tool. As the researchers put it: “The language of Twitter may be window into the aggregated and powerful effects of the community context.”
“Given that the typical Twitter user is younger (median age 31) than the typical person at risk for atherosclerotic heart disease, it is not obvious why Twitter language should track heart disease mortality,” writes a research team led byJohannes Eichstaedt and Hansen Andrew Schwartz of the University of Pennsylvania. “The people tweeting are not the people dying. However, the tweets of younger adults may disclose characteristics of their community, reflecting a shared economic,
physical, and psychological environment.”
The researchers analyzed 148 million messages tweeted from 1,347 American counties between June 2009 and March 2010. Emotional language was measured in two ways: the use of common terms associated with concepts such as anger, anxiety, and “positive and negative social relationships” and clusters of words reflecting certain attitudes and topics, including hostility and aggression, boredom and fatigue, optimism, and positive experiences.
“Engagement (that is, participation in community activities), which has long been considered an important component of successful aging, emerged as the strongest protective factor in our study,” the researchers add.
These results support the notion that social media can be a very useful research tool. As the researchers put it: “The language of Twitter may be window into the aggregated and powerful effects of the community context.”
Perhaps more importantly to the average person, they also point to a truth we sometimes forget: Living among the perpetually enraged or chronically disengaged may be hazardous to your health.
