Consumption of sugar-sweetened carbonated beverages (including soda) has declined nationally, but trends by state are unknown. Authors used data 2011 through 2016 California Health Interview Survey (CHIS) to assess overall changes in soda consumption among adults aged 18 or older and identified differences by education and income level.

Findings:

• Frequency of soda consumption (times per week) declined from 2011 through 2014 by 16.5% but returned to 2011 levels in 2015 and 2016.
• Trends did not differ by education or income.
• The proportion of the population that consumed soda did not change among adults with less than a high school diploma or equivalent, but declined significantly among those with at least a high school diploma.
