RESUMO

INTRODUCTION: Fiscal policies can shift relative food prices to encourage the purchase and consumption of minimally processed foods while discouraging the purchase and consumption of unhealthy ultraprocessed foods, high in calories and nutrients of concern (sodium, sugar, and saturated fats), especially for low-income households. METHODS: The 2017-2018 packaged food purchase data among U.S. households were used to derive household income- and composition-specific demand elasticities across 22 food and beverage categories. Policy simulations, conducted in 2022-2023, assessed the impact of national taxes on unhealthy ultraprocessed food and beverage purchases, both separately and alongside subsidies for minimally processed foods and beverages targeted to low-income households. Resultant nutritional implications are reported on the basis of changes in purchased calories and nutrients of concern. In addition, financial implications for both households and the federal government are projected. RESULTS: A sugar-based tax on sugar-sweetened beverages would lower both volume and calories purchased with the largest impact on low-income households without children. Meanwhile, targeted subsidies would increase fruit, vegetable, and healthier drink purchases without substantially increasing calories. Under tax simulations, low-income households would make larger reductions in their absolute volume and calorie purchases of taxed foods and beverages than their higher-income counterparts, suggesting that these policies, if implemented, could help narrow nutritional disparities. CONCLUSIONS: Levying national taxes on unhealthy ultraprocessed foods/beverages and offering targeted subsidies for minimally processed foods/beverages could promote healthier food choices among low-income households. Such policies have the potential to benefit low-income households financially and at a relatively low cost for the federal government annually.

RESUMO

High levels of food processing can have detrimental health effects independent of nutrient content. Experts and advocates have proposed adding information about food processing status to front-of-package labeling schemes, which currently exclusively focus on nutrient content. How consumers would perceive "ultraprocessed" labels has not yet been examined. To address this gap, we conducted a within-subjects online experiment with a convenience sample of 600 US adults. Participants viewed a product under three labeling conditions (control, "ultraprocessed" label, and "ultraprocessed" plus "high in sugar" label) in random order for a single product. The "ultraprocessed" label led participants to report thinking more about the risks of eating the product and discouraging them from wanting to buy the product more than the control, despite not grabbing more attention than the control. The "ultraprocessed" plus "high in sugar" labels grabbed more attention, led participants to think more about the risks of eating the product, and discouraged them from wanting to buy the product more than the "ultraprocessed" label alone. "Ultraprocessed" labels may constitute promising messages that could work in tandem with nutrient labels, and further research should examine how they would influence consumers' actual intentions and behaviors.

RESUMO

Background: Families participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) experienced barriers to accessing healthy food during the COVID-19 pandemic, but we do not yet understand how WIC participant food purchases shifted during the pandemic. Objectives: We aimed to describe the association between the initial shock of the pandemic in March 2020 and WIC shoppers' food purchases and changes in purchases before and during the pandemic at a top grocery chain and examine differences in these relationships by duration of WIC use. Methods: We used longitudinal food transaction data from WIC shoppers (n = 2,989,116 shopper-month observations from 175,081 unique WIC shoppers) from 496 stores in a top grocery store chain in North Carolina between October 2019 and May 2021. We used an interrupted time series design to describe the following: 1) the relationship between the initial shock of the pandemic and WIC shopper food purchases and 2) differences in purchases before and during the pandemic. To assess differences in purchases between shoppers consistently using WIC electronic benefit transfer (EBT) cards and shoppers starting or stopping WIC EBT use during the pandemic, we used models stratified by WIC group. Primary outcomes were share (%) of total calories purchased from fruits, vegetables, nuts, and legumes (FV), processed foods, and sugar-sweetened beverages (SSBs). Results: We observed small decreases in the share of total calories from FV (-0.4%) and small increases in the share of calories from processed food (1.1%) and SSBs (0.5%) purchased at this retailer when comparing the pre and post March 2020 periods. Compared with shoppers that started or stopped using WIC benefits during the pandemic, shoppers that used WIC benefits consistently had slightly higher FV and lower processed food and SSB purchases at this retailer. Conclusions: Future studies should examine whether additional supports for nutrient-dense food choices may be needed for families with low incomes in public health emergencies.

RESUMO

BACKGROUND: More than one-third of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants identify as Latino, but participation has been declining and individuals who speak predominantly Spanish face additional barriers to participation. During the COVID-19 pandemic, there were changes in WIC eligibility and benefits that may have been differentially accessible to Spanish-speaking Latina participants due to factors such as language barriers and lack of awareness of changes. Understanding Spanish-speaking Latinas' experiences with the WIC program generally and during the pandemic can inform efforts to equitably implement future emergency food response policies and improve the WIC program and Latina participant enrollment more broadly. OBJECTIVE: This study aimed to understand the perceptions and experiences of Spanish-speaking Latina WIC participants with the WIC program generally and with COVID-19 pandemic-related policy changes made to the WIC program. DESIGN: Qualitative in-depth interviews were conducted virtually in Spanish in August 2022 using a semi-structured guide. PARTICIPANTS/SETTING: Study participants were 18 Spanish-speaking Latina adult WIC participants living in North Carolina recruited using convenience sampling. ANALYSIS: All interviews were recorded, transcribed, and coded in Spanish. Thematic analysis with inductive coding was used to derive key themes. RESULTS: Perceptions about the WIC program in this sample were mixed. Participants felt positively about the healthfulness of foods included in the WIC food packages but expressed concern about the monthly benefit amounts being too low and the cultural appropriateness of food options. Pandemic policy changes, such as remote appointments and the Cash Value Benefit increase were perceived positively; however, barriers to using benefits during this time included limited communication from WIC agencies, food shortages, and concerns about not being granted US citizenship or permanent resident status due to use of WIC (ie, public charge rule). Social networks played an important role in learning about and enrolling in WIC and navigating food shortages during the pandemic. CONCLUSIONS: Concerns about the cultural appropriateness of foods provided, communication challenges, and the public charge rule emphasized the need for resources dedicated in the WIC program to improving Spanish-speaking Latina women's experiences with WIC.

RESUMO

OBJECTIVE: To assess the impact of the Philadelphia Beverage Tax on perceived beverage healthfulness, and awareness and opinions of the tax. DESIGN: Natural experiment SETTING: Small independent stores in Philadelphia (n = 61) and Baltimore (untaxed control site; n = 65) PARTICIPANTS: Shoppers in Philadelphia (n = 2,731) and Baltimore (n = 4,600) pre- and post-tax implementation. MAIN OUTCOME MEASURES: Perceptions of 4 beverages (unhealthy vs healthy/neutral), tax awareness, and tax opinions (oppose vs favor/neutral). ANALYSIS: Mixed-effects linear probability models estimated changes in perceived beverage healthfulness in Philadelphia, relative to Baltimore, following a difference-in-differences approach. Mixed-effects linear probability models estimated pre-post changes in tax awareness and opinions in Philadelphia-only. RESULTS: The probability of perceiving taxed beverages as unhealthy increased 2-years post-tax relative to Baltimore (regular soda: 5.7% [95% confidence interval (CI), 0.9-10.6], P = 0.02; diet soda: 7.7% [95% CI, 1.5-13.8], P < 0.001; sports drinks: 6.4% [95% CI, 0.4-12.4], P = 0.04), with similar changes at 1-year post-tax, whereas perceived healthfulness of untaxed 100% fruit juice did not change. Tax awareness was high at baseline (72%) and increased post-implementation; however, the probability of opposing the tax (22%) also increased over time. CONCLUSIONS AND IMPLICATIONS: Decreases in the perceived healthfulness of taxed beverages suggest the tax had a health-signaling effect. Consumer awareness and health education efforts could complement tax policies to enhance understanding of health risks.

RESUMO

OBJECTIVE: Given the rapidly changing food environment and proliferation of ultra-processed foods (UPF) in South Africa (SA), this study aimed to critically evaluate dietary quality and adequacy of low-income adults using the Nova classification system and WHO and World Cancer Research Fund dietary guidelines. DESIGN: Secondary household data and 1-d 24-h recalls were analysed from two cross-sectional studies conducted in 2017-2018. Foods consumed were classified according to the Nova classification system. Compliance with WHO dietary guidelines and UPF consumption trends were evaluated. SETTING: Three low-income areas (Langa, Khayalitsha and Mount Frere) in SA were included. PARTICIPANTS: In total, 2521 participants (18-50 years) were included in the study. RESULTS: Participants had a mean energy intake of 7762 kJ/d. Most participants were within the acceptable WHO guideline range for saturated fat (80·4 %), total fat (68·1 %), Na (72·7 %) and free sugar (57·3 %). UPF comprised 39·4 % of diets among the average adult participant. Only 7·0 % of all participants met the WHO guideline for fruit and vegetables and 18·8 % met the guideline for fibre. Those within the highest quartile of share of energy from UPF consumed statistically higher amounts of dietary components to limit and were the highest energy consumers overall. CONCLUSIONS: Low-income adults living in SA are consuming insufficient protective dietary components, while UPF consumption is prevalent. Higher UPF consumers consume larger amounts of nutrients linked to increased chronic disease risk. Policy measures are urgently needed in SA to protect against the proliferation of harmful UPF and to promote and enable consumption of whole and less UPF.

RESUMO

BACKGROUND: Excess sugar consumption is a public health concern in the United States. How sugar purchases have changed over time, whether there are disparities across subpopulations, and the contribution of various food groups are unclear. OBJECTIVE: To assess trends in sugar from packaged foods and beverages purchased by US households between 2002 and 2020. DESIGN: This is an open cohort study. PARTICIPANTS/SETTING: We obtained data from the NielsenIQ U.S. Homescan Consumer Panel, which collects data on household purchases of all consumer packaged goods in 52 metropolitan and 24 non-metropolitan markets across the United States. We assessed data on food and beverage purchases for 1,163,447 household-years. MAIN OUTCOME MEASURES: The primary outcomes are the total sugar in grams purchased per capita per day and percentage of calories from sugar, by sociodemographic group. STATISTICAL ANALYSES PERFORMED: We used linear regression to estimate trends in total grams of sugar per capita per day, percentage of calories from sugar, and percentage of total sugar purchases by food or beverage group. We estimated means for select years and tested for significance compared with 2002 and with the previous timepoint and calculated the overall P-value for the linear trend using time series regression. RESULTS: Total sugar purchases decreased over the study period, both in absolute terms (-37.2 g/capita/day; 95% confidence interval [CI], -38.7, -35.6) and as a percentage of total calories purchased (-5.3 percentage points; 95% CI, -5.5, -5.2). Sugar purchases declined for all sociodemographic groups, but disparities have persisted or widened, particularly among individuals who are non-Hispanic Black, low-income, and with lower educational attainment. Beverages' contributions to sugar purchases decreased 8.1 percentage points (95% CI, -8.4, -7.8). CONCLUSION: In the United States, purchases of sugar declined, but disparities by socioeconomic status and race or ethnicity persisted or widened. Policies to further reduce sugar consumption and the burden of diet-related disparities are needed.

RESUMO

In 2014, Mexico implemented a tax on sugar-sweetened beverages (SSB) equivalent to one Mexican peso (MP) per liter to address the high obesity prevalence. This tax has effectively reduced SSB purchases and yielded healthcare savings; however, it remains unknown whether SSB taxes lead to net benefits at the societal level in Mexico. Moreover, public health experts recommend increasing the tax. The objective of this study is to estimate the net benefits of SSB taxes compared to a scenario of no tax in urban Mexico. Taxes include the one-MP tax and alternative higher taxes (two and three MP per SSB liter). Thus, we conducted a cost-benefit analysis from the perspective of the government, producers, and consumers for a simulated closed cohort of adults in a life-table model. We defined net benefits as the difference between economic benefits (the value of statistical life, healthcare savings, and tax revenue) and costs (consumer surplus and profit losses). We found that, at the societal level, all simulated taxes will eventually generate benefits that surpass costs within ten years. Overall net benefits can reach USD 7.1 billion and 15.3 billion for the one-MP and the three-MP tax, respectively. Hence, these benefits increased at a declining rate compared to taxes. The government and consumers will experience overall positive net benefits among society's members. Policymakers should consider time horizons and tradeoffs between health gains and economic outcomes across different society members.

RESUMO

To support implementation of important public health policies, policymakers need information about implementation costs over time and across stakeholder groups. We assessed implementation costs of two federal sugar-sweetened beverage (SSB) policies of current policy interest and with evidence to support their effects: excise taxes and health warning labels. Our analysis encompassed the entire policy life cycle using the Exploration, Preparation, Implementation, and Sustainment framework. We identified implementation actions using key informant interviews and developed quantitative estimates of implementation costs using published literature and government documents. Results show that implementation costs vary over time and among stakeholders. Explicitly integrating implementation science theory and using mixed methods improved the comprehensiveness of our results. Although this work is specific to federal SSB policies, the process can inform how we understand the costs of many public health policies, providing crucial information for public health policy making.

RESUMO

OBJECTIVE: This study 1) compares grocery sales to Supplemental Nutrition Assistance Program (SNAP) shoppers in rural and urban grocery stores and 2) estimates changes in sales to SNAP shoppers in North Carolina (NC) since the pandemic. DESIGN: Weekly transaction data among loyalty shoppers at a large grocery chain across NC from October 2019 to December 2020 (n = 32; 182 store weeks) to assess nutritional outcomes. SETTING: North Carolina large chain grocery stores. PARTICIPANTS: Large chain grocery store/SNAP shoppers. INTERVENTION: Rural/urban status of the stores and COVID-19 pandemic onset. MAIN OUTCOME MEASURES: Share of total calories sold from fruits, vegetables, nuts, and legumes (FVNL) with and without additives, sugar-sweetened beverages (SSB), less healthful foods (LHF), and processed meats (PM). ANALYSIS: Multivariate random effects models with robust standard errors to examine the association of rural/urban status before and since coronavirus disease 2019 with the share of calories sold to SNAP shoppers from each food category. We controlled for county-level factors (eg, sociodemographic composition, food environment) and store-level factors. RESULTS: We did not find significant rural-urban differences in the composition of sales to SNAP shoppers in adjusted models. There was a significant decrease in the mean share of total calories from sugar-sweetened beverages (-0.43%) and less healthful food (-1.32%) and an increase in the share from processed meats (0.09%) compared with before the pandemic (P < 0.05). CONCLUSIONS AND IMPLICATIONS: Urban-rural definitions are insufficient to understand nuances in food environments, and more support is needed to ensure healthy food access.

RESUMO

With the growing burden of non-communicable diseases (NCDs), countries across the globe are finding ways to reduce the consumption of ultra-processed food and drinks including sugar-sweetened beverages (SSBs). South Africa implemented a health promotion levy (HPL) in April 2018 as one strategy to reduce sugar intake. Such efforts are frequently countered or mitigated by industry action in various ways, including through marketing and advertising strategies. To better understand trends in the extent of advertising, this paper analyses advertising expenditures and exposure of children to SSB advertisements in South Africa. Using Nielsen's monthly data on advertising expenditure before and after the introduction of the HPL, for the period January 2013 to April 2019, the results show that manufacturers spent ZAR 3683 million to advertise their products. Advertising expenditure on carbonated drinks accounted for over 60% (ZAR 2220 million) of the total expenditure on SSBs. The results also show that companies spend less in advertising powdered SSBs (an average of ZAR 0.05 million per month). Based on expenditure patterns, television (TV) was the preferred medium of advertisements, with companies prioritizing what is often considered children's and family viewing time. Urgent mandatory regulations are needed to prevent child-directed marketing.

RESUMO

Background: Chile's landmark food labeling and advertising policy led to major reductions in sugar purchases. However, it is unclear whether this led to increases in the purchases of nonnutritive sweeteners (NNS). Objectives: The objective of this study was to assess the changes in NNS and caloric-sweetened (CS) products purchased after the law's first phase. Methods: Longitudinal data on food and beverage purchases from 2,381 households collected from January 1, 2015 to December 31, 2017, were linked to nutritional information and categorized into added sweetener groups (unsweetened, NNS-only, CS-only, or NNS with CS). Logistic random-effects models and fixed-effects models were used to compare the percentage of households purchasing products and the mean volume purchased by sweetener category to a counterfactual based on pre-regulation trends. Results: Compared with the counterfactual, the percentage of households purchasing any NNS beverages (NNS-only or NNS with CS) increased by 4.2 percentage points (pp) (95% CI: 2.8, 5.7; P < 0.01). This increase was driven by households purchasing NNS-only beverages (12.1 pp, 95% CI: 10.0, 14.2; P < 0.01). The purchased volume of beverages with any NNS increased by 25.4 mL/person/d (95% CI: 20.1, 30.7; P < 0.01) or 26.5%. Relative to the counterfactual, there were declines of -5.9 pp in households purchasing CS-only beverages (95% CI: -7.0, -4.7; P < 0.01). Regarding the types of sweeteners purchased, we found significant increases in the amounts of sucralose, aspartame, acesulfame K, and steviol glycosides purchased from beverages. Among foods, differences were minimal. Conclusions: The first phase of Chile's law was associated with an increase in the purchases of beverages containing NNS and decreases in beverages containing CS, but virtually no changes in foods.

RESUMO

OBJECTIVE: Our objectives were to describe sociodemographic characteristics associated with the purchase of (1) any fruit drinks and (2) fruit drinks with specific front-of-package (FOP) nutrition claims. DESIGN: Cross-sectional. SETTING: USA. PARTICIPANTS: We merged fruit drink purchasing data from 60 712 household-months from 5233 households with children 0-5 years participating in Nielsen Homescan in 2017 with nutrition claims data. We examined differences in predicted probabilities of purchasing any fruit drinks by race/ethnicity, income and education. We constructed inverse probability (IP) weights based on likelihood of purchasing any fruit drinks. We used IP-weighted multivariable logistic regression models to examine predicted probabilities of purchasing fruit drinks with specific FOP claims. RESULTS: One-third of households with young children purchased any fruit drinks. Non-Hispanic (NH) Black (51·6 %), Hispanic (36·3 %), lower-income (39·3 %) and lower-educated households (40·9 %) were more likely to purchase any fruit drinks than NH White (31·3 %), higher-income (25·8 %) and higher-educated households (30·3 %) (all P < 0·001). In IP-weighted analyses, NH Black households were more likely to purchase fruit drinks with 'Natural' and fruit or fruit flavour claims (6·8 % and 3·7 %) than NH White households (4·5 % and 2·7 %) (both P < 0·01). Lower- and middle-income (15·0 % and 13·8 %) and lower- and middle-educated households (15·4 % and 14·5 %) were more likely to purchase fruit drinks with '100 % Vitamin C' claims than higher-income (10·8 %) and higher-educated households (12·9 %) (all P < 0·025). CONCLUSIONS: We found a higher likelihood of fruit drink purchases in lower-income, lower-educated, NH Black and Hispanic households. Experimental studies should determine if nutrition claims may be contributing to disparities in fruit drink consumption.

RESUMO

OBJECTIVE: To determine whether an increase in hourly wages was associated with changes in food security and perceived stress among low-wage workers. We also determined whether changes in food security and stress were associated with changes in diet. SETTING: Wages is a prospective cohort study following 974 low-wage workers in Minneapolis, MN, where an ordinance is incrementally increasing minimum wage to US$15/hr from 2018 to 2022, and a comparison community with no minimum wage ordinance (Raleigh, NC). Interaction models were estimated using generalized estimating equations. PARTICIPANTS: Analyses used two waves of data (2018 [baseline], 2019) and included 219 and 321 low-wage workers in Minneapolis and Raleigh (respectively). RESULTS: Average hourly wages increased from US$9.77 (SD US$1.69) to US$11.67 (SD US$4.02). Changes in wages were not associated with changes in food security (odds ratio = 1.05, 95% confidence interval [CI] [0.89, 1.23], p = .57) or stress (ß = -0.01, 95% CI [-0.04, 0.03], p = .70) after 1 year of policy implementation. Changes in food security were not associated with changes in diet. However, we found significant changes in the frequency of fruit and vegetable intake across time by levels of stress, with decreased intake from Wave 1 to 2 at low levels of stress, and increased intake at high levels of stress (incidence rate ratio = 1.17, 95% CI [1.05, 1.31], p = .01). CONCLUSIONS: Changes in wages were not associated with changes in food security or stress in a sample of low-wage workers. Future research should examine whether full implementation of a minimum wage increase is associated with changes in these outcomes.

RESUMO

Many low-income Americans experience food insecurity, which may have been exacerbated by economic instability during the early stages of the COVID-19 pandemic in 2020. In this study we assessed the impact of Healthy Helping, a short-term fruit and vegetable incentive program aimed at alleviating food insecurity and improving diet quality for Supplemental Nutrition Assistance Program participants, on grocery purchases, using transaction data from a large supermarket chain in North Carolina. We compared Healthy Helping participants' purchases of key food groups before and during the program with purchases by control shoppers participating in federal food assistance programs during the same period. Healthy Helping enrollment was associated with a $26.95 increase in monthly spending on fruit, vegetables, nuts, and legumes-an increase of 2.5 grams of fiber per 1,000 kilocalories purchased-and other shifts in the composition of food purchases, relative to control shoppers. These findings suggest that the program increased healthy food purchases while also increasing dollar sales at participating retailers. On average, participants did not use the full benefit; future research should explore factors associated with non- or underuse of benefits, to inform program design and outreach.

RESUMO

There has been a rapid proliferation of policies around the globe to reduce sugar consumption, yet there is little understanding as to whether these policies have led to changes in the overall sweetness of products, which is essential for understanding long-term effects on food preferences and intake. For example, the implementation of Chile's Law on Food Labeling and Advertising led to decreases in the sugar content of non-alcoholic packaged beverages and increases in non-nutritive sweeteners (NNS) use in these beverages. Given that NNS have greater sweetness intensity than sugars, it is unclear what was the net effect of these changes on the sweetness of purchased beverages. Using longitudinal household purchase data (n > 2,000 households), we measured the changes in the sweetness of beverage purchases after implementing the first phase of the Chilean law and examine if there were differences by key family sociodemographic variables. We developed three sweetness indices: (1) NNS sweetness, including the sweetness of the six NNS most consumed by Chileans; (2) total sugars sweetness, including the sweetness from total sugars; and (3) total sweetness, combining the sweetness from NNS and sugars. Using fixed-effects models, we compared the observed post-law purchases to a counterfactual based on pre-law trends. We found that NNS sweetness increased relative to the counterfactual, while total sugars sweetness decreased after the law. However, the absolute changes in NNS sweetness were almost entirely offset by the decreases in total sugar sweetness, leading to no change in the total sweetness of beverage purchases. Additionally, there were no differences in the sweetness changes by family sociodemographics. Our findings indicate that Chilean consumers are exposed to similar sweetness levels in their beverages after the law. Future research should explore whether sweetness also remained consistent in dietary intake.

RESUMO

INTRODUCTION: Simulation modeling methods are an increasingly common tool for projecting the potential health effects of policies to decrease sugar-sweetened beverage (SSB) intake. However, it remains unknown which SSB policies are understudied and how simulation modeling methods could be improved. To inform next steps, we conducted a scoping review to characterize the (1) policies considered and (2) major characteristics of SSB simulation models. METHODS: We systematically searched 7 electronic databases in 2020, updated in 2021. Two investigators independently screened articles to identify peer-reviewed research using simulation modeling to project the impact of SSB policies on health outcomes. One investigator extracted information about policies considered and key characteristics of models from the full text of included articles. Data were analyzed in 2021-22. RESULTS: Sixty-one articles were included. Of these, 50 simulated at least one tax policy, most often an ad valorem tax (e.g., 20% tax, n = 25) or volumetric tax (e.g., 1 cent-per-fluid-ounce tax, n = 23). Non-tax policies examined included bans on SSB purchases (n = 5), mandatory reformulation (n = 3), warning labels (n = 2), and portion size policies (n = 2). Policies were typically modeled in populations accounting for age and gender or sex attributes. Most studies focused on weight-related outcomes (n = 54), used cohort, lifetable, or microsimulation modeling methods (n = 34), conducted sensitivity or uncertainty analyses (n = 56), and included supplementary materials (n = 54). Few studies included stakeholders at any point in their process (n = 9) or provided replication code/data (n = 8). DISCUSSION: Most simulation modeling of SSB policies has focused on tax policies and has been limited in its exploration of heterogenous impacts across population groups. Future research would benefit from refined policy and implementation scenario specifications, thorough assessments of the equity impacts of policies using established methods, and standardized reporting to improve transparency and consistency.

RESUMO

This study aimed to evaluate the effect of different labels on participants identifying products high in nutrients of concern; identifying unhealthy products, and intention to purchase unhealthy products. This blinded randomised controlled trial included a representative sample of South African households (n = 1951). Per household we selected a member primarily responsible for food purchases. Participants were randomised into the Warning Label (WL), Guideline Dietary Amounts (GDA) or Multiple Traffic Light (MTL) arms. Each participant answered questions in a no label condition (control) followed by same questions in the label condition (experiment). Complete data were collected and analysed for 1948 participants (WL = 33.7%, GDA = 32.1% and MTL = 34.2%). The probability of correctly identifying products high in nutrients of concern and identifying products as being unhealthy was higher with the WL compared to the GDA or MTL for most items. There was no difference in performance between the GDA and the MTL when considering all items together. A higher percentage of participants reported a lower intention to purchase an unhealthy product after exposure to the WL compared to MTL for 5 out of 6 products; 2 out of 6 products for the WL compared to GDA and 2 out of 6 products for GDA compared to MTL. Compared to the control condition, exposure to each of the labels resulted in better identification of nutrients of concern, unhealthy products and a lower intention to purchase when considering all specific outcome items together. The WL showed a higher potential to enable South African consumers to identify products high in nutrients of concern, identify unhealthy products and discourage purchasing of unhealthy products.

RESUMO

OBJECTIVE: To estimate the prevalence of online grocery shopping in a nationally representative sample and describe demographic correlates with online grocery shopping. DESIGN: The Nielsen COVID-19 Shopper Behavior Survey was administered to a subset of Nielsen National Consumer Panel participants in July 2020. We used survey weighted-multivariable logistic regression to examine demographic correlates of having ever online grocery shopped. SETTING: Online survey. PARTICIPANTS: 18 598 Nielsen National Consumer Panel participants in the USA. RESULTS: Thirty-nine percent of respondents had purchased groceries online, and among prior purchasers, 89 % indicated that they would continue to online grocery shop in the next month. Canned/packaged foods were the most shopped for grocery category online, followed by beverages, fresh foods and lastly frozen foods. In adjusted analyses, younger respondents (39 years or less) were more likely (47 %) to have ever shopped for groceries online than older age groups (40-54 years, 55-64 years and 65+ years) (29 %, 22 % and 23 %, respectively, all P < 0·001). Those with greater than a college degree were more likely to have ever grocery shopped online (45 %) than respondents with some college education (39 %) and with a high school education or less (32 %) (both P < 0·001). Having children, having a higher income and experiencing food insecurity, particularly among higher income food-insecure households, were also associated with a higher probability of prior online grocery shopping. CONCLUSIONS: The COVID-19 pandemic accelerated the transition to online grocery shopping. Future research should explore the nutrition implications of online grocery shopping.

RESUMO

During the COVID-19 pandemic, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Cash Value Benefit (CVB) for fruits and vegetables increased by roughly USD 25/month/person. We sought to understand WIC participant perceptions of this change and barriers and facilitators to using the CVB. We conducted 10 virtual focus groups (5 rural, 5 urban/suburban) with WIC participants (n = 55) in North Carolina in March 2022. Focus groups were recorded and transcribed. We open-coded the content and used thematic analysis to uncover consistencies within and between sampled groups. Participants expressed favorable perceptions of the CVB increase and stated the pre-pandemic CVB amount was insufficient. Barriers to using the increased CVB were identifying WIC-approved fruits and vegetables in stores and insufficient supply of fruits and vegetables. Barriers were more pronounced in rural groups. Facilitators of CVB use were existing household preferences for fruits and vegetables and the variety of products that can be purchased with CVB relative to other components of the WIC food package. Participants felt the CVB increase allowed their families to eat a wider variety of fruits and vegetables. The CVB increase may improve fruit and vegetable intake, particularly if made permanent, but barriers to CVB and WIC benefit use may limit the potential impact.
