Prior research on the restaurant environment and obesity risk is limited by cross-sectional data and a focus on specific geographic areas.

Objective

Setting

USA (207 counties across 39 states).

Participants

447,873 adult patients who visited an athenahealth medical provider in 2012 and 2015 where BMI was measured.
