Analyzing social media use can help predict, track and map obesity rates

Statement from the Boston Children’s Hospital: “The higher the percentage of people in a city, town or neighborhood with Facebook interests suggesting a healthy, active lifestyle, the lower that area’s obesity rate. At the same time, areas with a large percentage of Facebook users with television-related interests tend to have higher rates of obesity. Such are the conclusions of a study by Boston Children’s Hospital researchers comparing geotagged Facebook user data with data from national and New York City-focused health surveys.

Together, the conclusions suggest that knowledge of people’s online interests within geographic areas may help public health researchers predict, track and map obesity rates down to the neighborhood level, while offering an opportunity to design geotargeted online interventions aimed at reducing obesity rates.
The study team, led by Rumi Chunara, PhD, and John Brownstein, PhD, of Boston Children’s Hospital’s Informatics Program (CHIP), published their findings on April 24 in PLOS ONE. The amount of data available from social networks like Facebook makes it possible to efficiently carry out research in cohorts of a size that has until now been impractical.”
