Abstract
Introduction: Multiple U.S. localities have introduced legislation requiring sugar-sweetened beverage (SSB) warnings. This study effects of different warning designs on beverage selections and perceptions.
Study Design: The study was an RCT.
Setting/Participants: An online virtual convenience store and survey were used with a nationally representative sample of primary caregivers of 6-11-year-olds (n=961). Data were collected in January 2020 and analyzed in May-July 2020.
Intervention: Participants were randomized to view SSBs with 1 of 4 front-of-package label designs: (1) no-warning control, (2) health-related text warning, (3) sugar pictorial warning (image of beverage sugar content in cubes/teaspoons/packets with health-related warning text), or (4) health pictorial warning (image of possible health consequences of overconsuming SSBs with health-related warning text).
Main outcome measures: Outcomes included participants' beverage choice for their child and perceptions of beverages, their assigned labels, and warning policies.
Results: Proportionally fewer participants chose a SSB in the sugar pictorial warning condition (-13.4 percentage points; 95% CI=-21.6 to-0.1 percentage points; p=0.007) and in the health picto-rial warning condition (-14.7 percentage points; 95% CI=-22.8 to-0.1 percentage points; p=0.004) compared to the control. Sugar pictorial warnings led to more accurate added-sugar content estimates than all conditions and greater label trust and support for sugar-sweetened beverage warning policies than health pictorial warnings.
Conclusions: SSB warning policies may be most effective if they mandate images of beverages' added sugar content accompanied by warning text.
