Annual variation in Internet keyword searches: Linking dieting interest to obesity and negative health outcomes

This study investigated the annual variation in Internet searches regarding dieting. Time-series analysis was first used to examine the annual trends of Google keyword searches during the past 7 years for topics related to dieting within the United States. The results indicated that keyword searches for dieting fit a consistent 12-month linear model, peaking in January (following New Year’s Eve) and then linearly decreasing until surging again the following January. Additional state-level analyses revealed that the size of the December–January dieting-related keyword surge was predictive of both obesity and mortality rates due to diabetes, heart disease, and stroke.
