Starting in July 2016, San Francisco, Calif., will require prominent warning labels on most sugar-sweetened beverage (SSB) advertisements (i.e., “WARNING: Drinking beverages with added sugar(s) contributes to obesity, diabetes, and tooth decay”). The purpose of this project is to collect baseline data on the presence and types of SSB print advertising visible in a sample of commercial blocks, sports venues, and transport locations in San Francisco and San Jose (control community). This will be part of a larger four-year study that will compare the presence of the warning label on covered advertising in San Francisco pre- to post-policy, compare the prevalence of advertising classes subject to regulation visible in both cities pre- and post-policy, and assess the characteristics of compliant and non-compliant advertising over time in relation to type and racial/ethnic targeting. Study findings will document the feasibility, effectiveness, and impact of warning labels as an obesity prevention tool.
