The impact of front-of-package claims, fruit images, and health warnings on consumers' perceptions of sugar-sweetened fruit drinks: Three randomized experiments.

ABSTRACT: We aimed to examine the impact of claims, fruit images, and health warnings on consumers' perceptions of fruit-flavored drinks with added sugar (i.e., "fruit drinks"). We conducted three 2x2x2 randomized experiments with online convenience samples of U.S. adults (Study 1 n = 2139 in 2018, current e-cigarette users and smokers; Study 2 n = 670 in 2018, current e-cigarette users; Study 3 n = 1006 in 2019, general sample). Participants viewed a fruit drink that differed in the presence of a "100% Vitamin C" claim, a fruit image, or a health warning. On average across the three studies, consumers who saw a claim on a fruit drink believed that the drink was more healthful than those who did not see the claim (mean average differential effect (ADE) = 0.66, p < .001); they were also more interested in consuming the drink (mean ADE = 0.38, p = .001). The health warning decreased perceived product healthfulness (mean ADE = -0.65, p < .001) and consumption interest (mean ADE = -0.49, p < .001). The fruit image had no effect on perceived product healthfulness (mean ADE = 0.03, p = .81) or purchase intentions (mean ADE = -0.04, p = .77). In Study 1 and Study 2, there were no interactions between claims, images, or warnings (all p > .05). In Study 3, the "100% Vitamin C" nutrition claim only increased perceived product healthfulness when the drink did not also have a health warning (interaction p < .05). These findings suggest that 100% Vitamin C claims increase the appeal of fruit drinks, whereas health warnings decrease the appeal. Together, these studies support policies to restrict marketing and require health warnings on sugar-sweetened beverage packaging.

Project description:BackgroundReducing red meat is a strategy to improve public health and mitigate climate change in the United States and other high-income countries. Policies requiring warnings on the front of red meat packages are a promising intervention to shift consumers towards healthier and more sustainable food choices. We aimed to explore participants' reactions to health and environmental warning messages about red meat.MethodsBetween June and July 2020, we recruited a national convenience sample of US red meat consumers (n = 1,235; mean age 44 years) for an online survey. Participants were randomly assigned to one of four label conditions: no-label control, health warning, environment warning, and combined health and environment warning (both warnings shown side-by-side). Participants viewed three types of burritos (red meat [steak], chicken, and vegetarian) and selected their preferred item (primary outcome), the item they perceived to be most damaging to health, and the item they perceived to be most damaging to the environment (secondary outcomes). Participants then viewed their assigned warning on a series of other red meat products (no-label control participants were randomly re-assigned to one of the warning conditions) and rated the warnings on perceived message effectiveness, believability, negative emotions, perceived risk, attention, and learning something new. Finally, participants reported their intentions to reduce red meat consumption.ResultsThere were no significant differences in selection of the steak burrito between label conditions or in selection of the item most damaging to the environment. Those exposed to the health warning were more likely to select the steak burrito as most damaging to health compared to those exposed to other label conditions (health 73 %, combined 64 %, environment 60 %, no-label control 63 %, p < 0.05). The combined and health warnings elicited higher perceived message effectiveness ratings than the environment warning (combined mean 2.91, health 2.84, environment 2.61, p < 0.05).ConclusionsWarnings did not have a significant effect on item preference in the choice experiment. However, combined and health warnings performed better than the environment warning across a variety of warning label reaction measures. More research will be needed to understand whether warnings elicit behavioral change in real-world environments.Trial registrationAnalyses and hypotheses were preregistered on https://aspredicted.org/ph7mb.pdf on 23 June 2020.

Project description:IntroductionFive U.S. states have proposed policies to require health warnings on sugar-sweetened beverages, but warnings' effects on actual purchase behavior remain uncertain. This study evaluated the impact of sugar-sweetened beverage health warnings on sugar-sweetened beverage purchases.Study designParticipants completed one study visit to a life-sized replica of a convenience store in North Carolina. Participants chose six items (two beverages, two foods, and two household products). One item was randomly selected for them to purchase and take home. Participants also completed a questionnaire. Researchers collected data in 2018 and conducted analyses in 2019.Setting/participantsParticipants were a demographically diverse convenience sample of 400 adult sugar-sweetened beverage consumers (usual consumption ≥12 ounces/week).InterventionResearch staff randomly assigned participants to a health warning arm (sugar-sweetened beverages in the store displayed a front-of-package health warning) or a control arm (sugar-sweetened beverages displayed a control label).Main outcome measuresThe primary trial outcome was sugar-sweetened beverage calories purchased. Secondary outcomes included reactions to trial labels (e.g., negative emotions) and sugar-sweetened beverage perceptions and attitudes (e.g., healthfulness).ResultsAll 400 participants completed the trial and were included in analyses. Health warning arm participants were less likely to be Hispanic and to have overweight/obesity than control arm participants. In intent-to-treat analyses adjusting for Hispanic ethnicity and overweight/obesity, health warnings led to lower sugar-sweetened beverage purchases (adjusted difference, -31.4 calories; 95% CI= -57.9, -5.0). Unadjusted analyses yielded similar results (difference, -32.9 calories; 95% CI= -58.9, -7.0). Compared with the control label, sugar-sweetened beverage health warnings also led to higher intentions to limit sugar-sweetened beverage consumption and elicited more attention, negative emotions, thinking about the harms of sugar-sweetened beverage consumption, and anticipated social interactions. Trial arms did not differ on perceptions of sugar-sweetened beverages' added sugar content, healthfulness, appeal/coolness, or disease risk.ConclusionsBrief exposure to health warnings reduced sugar-sweetened beverage purchases in this naturalistic RCT. Sugar-sweetened beverage health warning policies could discourage sugar-sweetened beverage consumption.Trial registrationThis study is registered at www.clinicaltrials.gov NCT03511937.

Project description:BackgroundSugar-sweetened drinks (SSDs) are known to be cariogenic, but this association has not been well investigated in population-based repeated cross-sectional studies in recent years. Therefore, this study examined whether SSD intake is associated with higher caries experience in 10- and 15-year-olds.MethodsThe study sample included participants from the Munich study centre of two birth cohorts with data on non-cavitated caries lesions (NCCL/S), caries experience (DMF/S index), overall caries burden (DMF + NCCL/S) and SSD intake. In total, 915 and 996 children were included from the 10- and 15-year follow-ups, respectively. Intake (g/day) of SSDs, comprising cola, lemonade, ice-tea, sport/energy drinks, fruit squashes and nectars, was calculated from food frequency questionnaires. For analyses, the SSD intake was converted into portions (250 ml/day). Multiple logistic regression and prospective analysis models were performed to test associations between SSD intake and various definitions of caries, adjusting for sex, parental education, body mass index (BMI) categories, study cohort, plaque-affected sextants, mode of SSD consumption, energy content of SSDs, and total energy intake.ResultsThe mean overall caries burden at 10 and 15 years of age was 1.81 (SD: 2.71) and 6.04 (SD: 8.13), respectively. The average consumption of SSDs at the 10- and 15-year follow-ups was 0.48 (SD: 0.85) and 0.83 (SD 1.40) portions/day, respectively. After adjusting for confounders, in 10-year-olds, SSD intake was significantly associated with higher caries experience based on the indices DMF/S (adjusted odds ratio: 1.29; 95% CI: 1.06-1.57), NCCL/S (1.24; 1.03-1.49) and DMF + NCCL/S (1.27; 1.05-1.55). At the 15-year follow-up, SSD consumption was significantly associated with increased DMF/S index (1.12; 1.01-1.25) only. Prospective model associating 10-year SSD intake with 15-year caries experience was not significant.ConclusionsSSD intake significantly increases the caries burden in 10-year-olds, with attenuated effects in 15-year-olds. To prevent caries, SSD consumption should be reduced, especially in children and adolescents.
