Secular Trends in Soda Consumption, California, 2011-2016

Area of Science:

• Public Health
• Epidemiology
• Nutrition Science

Background:

• National trends show declining sugar-sweetened carbonated beverage consumption.
• State-level trends and demographic disparities in soda consumption are not well understood.
• California represents a significant population for studying beverage consumption patterns.

Purpose of the Study:

• To analyze changes in soda consumption among California adults from 2011 to 2016.
• To identify differences in soda consumption trends based on education and income levels.
• To assess the ongoing public health impact of soda consumption in California.

Main Methods:

• Utilized data from the California Health Interview Survey (CHIS).
• Analyzed self-reported soda consumption frequency (times per week) among adults aged 18+.
• Examined trends in the proportion of the population consuming soda by education and income.

Main Results:

• Overall soda consumption frequency declined 16.5% from 2011-2014, then reverted to 2011 levels by 2016.
• No significant differences in consumption trends were observed across education or income levels.
• The proportion of adults consuming soda decreased among those with at least a high school diploma but remained unchanged for those with less than a high school diploma.

Conclusions:

• Soda consumption remains a significant public health issue in California.
• While overall consumption trends fluctuated, educational attainment influenced changes in soda consumption.
• Targeted public health interventions may be necessary to address persistent soda consumption disparities.
