Pyke K, Palermo C, Kleve S. The role of collective impact in improving nutrition. A scoping review. Nutr Diet 2024; 81:28-34. [PMID: 37331724 DOI: 10.1111/1747-0080.12831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 05/17/2023] [Accepted: 06/01/2023] [Indexed: 06/20/2023]
Abstract
BACKGROUND Collective impact is gaining traction to improve population health outcomes. This study aimed to determine where and how collective impact is being used in nutrition and describe current understandings of its impacts or results on health or nutrition outcomes. METHODS A systematic scoping review was undertaken with four databases ('CINAHL Plus', 'Sociological Abstracts', 'PsychInfo', and 'OVID Medline') using the search term 'Collective Impact' from 2011 up to November 2022. All studies were screened independently by two authors. Data were extracted and synthesised narratively. RESULTS A total of 712 different documents were identified, with four studies included in the synthesis. Collective impact approaches focussed on breastfeeding, reducing sugar-sweetened beverage consumption, increasing access to healthy food, and obesity. Across the four included studies, promising results in improving health and nutrition were reported. CONCLUSION Evaluating and reporting on the outcomes of collective impact initiatives in nutrition using robust methods is needed.

Khan A, Evangelista AU, Varua ME. Evaluating the impact of marketing interventions on sugar-free and sugar-sweetened soft drink sales and sugar purchases in a fast-food restaurant setting. BMC Public Health 2023; 23:1578. [PMID: 37596602 PMCID: PMC10439673 DOI: 10.1186/s12889-023-16395-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Accepted: 07/26/2023] [Indexed: 08/20/2023] Open
Abstract
BACKGROUND Beverages high in added sugar, such as sugar-sweetened soft drinks, continue to be associated with various health issues. This study examines the effects of a manufacturer-initiated multicomponent intervention on the sales of sugar-free (SFD) and sugar-sweetened (SSD) soft drinks and the amount of sugar people purchase from soft drinks in a fast-food restaurant setting. METHODS A database of monthly sales data of soft drinks from January 2016 to December 2018 was obtained from three treatment and three control fast-food restaurants. A multicomponent intervention consisting of free coupons, point-of-purchase displays, a menu board, and two sugar-free replacements for sugar-sweetened soft drinks was introduced in August 2018 for five months in Western Sydney, Australia. A retrospective interrupted time series analysis was used to model the data and examine the effects of the interventions on SFD and SSD sales and their consequential impact on sugar purchases from soft drinks. The analyses were carried out for volume sales in litres and sugar in grams per millilitre of soft drinks sales. A comparison of these measures within the treatment site (pre- and post-intervention) and between sites (treatment and control) was conducted. RESULTS The interventions had a statistically significant impact on SFDs but not SSDs. On average, SFD sales in the treatment site were 56.75% higher than in the control site. Although SSD sales were lower in the treatment site, the difference with the control site was not statistically significant. The net reduction of 6.34% in the amount of sugar purchased from soft drinks between sites during the experimental period was attributed to the interventions. CONCLUSIONS The interventions significantly increased SFD sales and reduced sugar purchases in the short run. Aside from free coupons, the findings support the recommendation for fast food restaurants to nudge customers towards choosing SFDs through point-of-purchase displays and the replacement of popular SSDs with their SFD counterparts.

J Med Internet Res 2023; 25:e46345. [PMID: 37450325 PMCID: PMC10382952 DOI: 10.2196/46345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/27/2023] [Accepted: 04/19/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Social media platforms are frequently used in health communication campaigns. Common understandings of campaign effects posit a sequential and linear series of steps from exposure to behavior change, commonly known as the hierarchy of effects model (HOE). These concepts need to be reevaluated in the age of social media, which are interactional and communal. OBJECTIVE This review aims to update the traditional HOE for health communication campaigns in the context of social media, including identifying indicators of effectiveness and how these are conceptualized to lead to health-related outcomes. METHODS We conducted a systematic review of studies following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines reporting on the use of social media as part of health communication campaigns, extracting campaign information such as objectives, platforms used, and measures of campaign performance. We used these data, combined with our understanding of the HOE, to develop an updated conceptual model of social media campaign effects. RESULTS We identified 99 eligible studies reporting on 93 campaigns, published between 2012 and 2022. The campaigns were conducted in over 20 countries, but nearly half (n=42) were conducted in the United States. Campaigns targeted a variety of health issues and predominantly used Facebook, Twitter, Instagram, and YouTube. Most campaigns (n=81) set objectives targeting awareness or individual behavior change. Process measures (n=68; eg, reach and impressions) and engagement measures (n=73; eg, likes and retweets) were reported most frequently, while two-fifths (n=42) did not report any outcomes beyond engagement, such as changes in knowledge, behavior, or social norms. Most campaigns (n=55) collected measures that did not allow them to determine if the campaign objective had been met; that is, they were process evaluations only. Based on our review, our updated model suggests that campaign exposure can lead to individual behavior change and improved health outcomes, either through a direct or indirect pathway. Indirect pathways include exposure through social and policy changes. "Engagement" is positioned as critical to success, replacing awareness in the traditional HOE, and all types of engagement are treated as equal and good. No consideration is being given to potential negative engagement, such as the distribution of misinformation. Additionally, the process is no longer linear and sequential, with circular pathways evident, such as engagement not only influencing behavior change but also generating additional exposure to campaign messages. CONCLUSIONS Our review has highlighted a change in conventional understandings of how campaigns can influence health outcomes in the age of social media. The updated model we propose provides social media campaigners with a starting point to develop and tailor campaign messages and allows evaluators to identify critical assumptions to test, including the role and value of "engagement."

Abstract
New technologies are supported by the global implementation of the internet. These improvements have deeply affected various disciplines of sciences and consequently changed services such as daily business, particularly health sectors. Innovative digital marketing strategies utilize the channels of social media and retrieved user data to analyze and improve relevant services. These multidisciplinary innovations can assist specialists, physicians and researchers in diagnostic, prophylaxis and treatment issues in the health sector. Accordingly, compared to recent decades, health decision makers are more accurate and trustful in defining new strategies. Interestingly, using social media and mobile health apps in current pandemics of SARS-CoV-2 could be an important instance of the key role of these platforms at the local and global level of health policies. These digital technologies provide platforms to connect public health sectors and health politicians for communicating and spreading relevant information. Adding influencers and campaigns to this toolbox strengthens the implementation of public health programs. In 2016, the WHO adopted a global program to eliminate viral hepatitis by 2030. Recent constructive measures that have been used in the battle against COVID-19 could be adopted for the elimination of viral hepatitis program. The presented evidence in our narrative review demonstrates that the application of digital marketing tools to create campaigns on social media, armed with professional influencers, can efficiently consolidate this program. The application of different strategies in using these popular tools will raise the public awareness about viral hepatitis. Subsequently, the availability of an effective vaccine for HBV and antiviral medication for HCV can motivate the audience to take steps towards prophylaxis and screening methods against these infectious illnesses. The encouragement of health policy makers to apply digital communication technologies and comprehensive roadmaps to implement this global program will certainly decrease the burden of viral hepatitis worldwide.

A systematic scoping review to inform future research to reduce sugary beverage health risks. Obes Rev 2022; 23:e13425. [PMID: 35142020 PMCID: PMC9286342 DOI: 10.1111/obr.13425] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 01/01/2022] [Accepted: 01/01/2022] [Indexed: 12/29/2022]
Abstract
Sugary beverage consumption is associated with many health risks. This study used a proof-of-concept media campaign typology to examine U.S. beverage campaigns that promoted healthy beverages and encouraged or discouraged sugary beverages. We used a three-step systematic scoping review to identify, organize, analyze, and synthesize evidence. Step 1 used Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines to search four electronic databases and gray literature through 2021. Step 2 categorized relevant media campaigns using a media campaign typology. Step 3 examined campaign evaluation outcomes. We identified 280 campaigns organized into six campaign typology categories. The media landscape was dominated by corporate marketing campaigns for branded sugary beverages (65.8%; n = 184) followed by public awareness (9.6%; n = 27), public policy (8.2%; n = 23), social marketing (7.1%; n = 20), corporate social responsibility (5.7%; n = 16), and countermarketing (3.6%; n = 10) campaigns. Evaluations for 20 unique campaigns implemented over 30 years (1992-2021) across 14 states showed reduced sugary beverage or juice and increased water or low-fat milk sales and intake. Positive short-term cognitive and mid-term retail and behavioral changes were reported. There was limited evidence for long-term policy, social norm, and population health outcomes. Future research is needed to use media campaigns in strategic communications to reduce sugary beverage health risks for Americans.

Abstract
Mass media advertising promoting healthy weight and lifestyles represents an important approach to the prevention of non-communicable diseases. However, concerns have been raised that advertisements promoting a healthy weight may be stigmatizing and contribute to negative outcomes. This study explored the potential negative and positive cognitive, psychological, and behavioral intention outcomes of exposure to different public health campaign advertisements that promote positive behavior change and healthy weight. A total of 1,098 adult residents of the United Kingdom (50% female, Mage = 35.21 years) viewed one of four video advertisements: one control advertisement and three healthy weight and lifestyle advertisements that differed in message content (negative health impacts, support/encouragement, and social norms) and execution style (graphic, animation, and depicted scene). Participants then responded to items assessing a variety of cognitive, psychological, and behavioral intention outcomes. Compared to those in the control condition, those exposed to a healthy weight and lifestyle advertisement reported significantly higher scores for (i) perceptions of weight stigma, (ii) negative emotions, and (iii) intentions to engage in adaptive lifestyle behaviors. There were no differences observed between conditions for maladaptive behavioral intentions, internalized weight bias, anti-fat attitudes, and body dissatisfaction. The advertisement featuring a supportive/encouraging message and animation style performed most favorably. Results suggest that healthy weight and lifestyle advertisements have the potential to promote positive behavior change but may be associated with some negative outcomes. Of the assessed communication approaches, a supportive/encouraging message with animation style appears least likely to induce negative emotions and is preferred for minimizing weight stigma.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115954. [PMID: 34206119 PMCID: PMC8199559 DOI: 10.3390/ijerph18115954] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 05/21/2021] [Accepted: 05/24/2021] [Indexed: 11/17/2022]
Abstract
Background: Social media offers a cost-effective and wide-reaching advertising platform for marketers. Objectively testing the effectiveness of social media advertising remains difficult due to a lack of guiding frameworks and applicable behavioral measures. This study examines advertising appeals’ effectiveness in driving engagement and actions on and beyond social media platforms. Method: In an experiment, positive, negative and coactive ads were shared on social media and promoted for a week. The three ads were controlled in an A/B testing experiment to ensure applicable comparison. Measures used included impressions, likes, shares and clicks following the multi-actor social media engagement framework. Data were extracted using Facebook ads manager and website data. Significance was tested through a series of chi-square tests. Results: The promoted ads reached over 21,000 users. Significant effect was found for appeal type on engagement and behavioral actions. The findings support the use of negative advertising appeals over positive and coactive appeals. Conclusion: Practically, in the charity and environment context, advertisers aiming to drive engagement on social media as well as behavioral actions beyond social media should consider negative advertising appeals. Theoretically, this study demonstrates the value of using the multi-actor social media engagement framework to test advertising appeal effectiveness. Further, this study proposes an extension to evaluate behavioral outcomes.

BMC Public Health 2021; 21:69.

Abstract
BACKGROUND Sugar-sweetened beverage (SSB) consumption is an important behavior that can influence individuals' risk for diabetes, obesity, and other chronic diseases. Nonetheless, there is a lack of valid measures to assess SSB-related constructs. Reliable and valid measures can help evaluate the efficacy of interventions designed to curb SSB consumption. Our aim was to develop a valid and reliable instrument to measure constructs related to SSB consumption in English and Spanish. METHODS A cross-sectional survey was conducted among a convenience sample of 150 adult residents of public housing developments in Boston, Massachusetts between July of 2016 and January of 2017. All households from two public housing developments were approached by study staff to solicit participation via door-to-door knocking and posted flyers. We developed questions to measure three SSB-related constructs informed by the Social Cognitive Theory: SSB knowledge, and self-efficacy and intention to act on SSB consumption. The questions were pilot tested in the population, and then administered in-person by bilingual study staff in either English or Spanish. Interviews were conducted most often in the participant's home and less frequently within a community space. Item normality was assessed with descriptive statistics. Difficulty of knowledge items was assessed with percent correct. Construct validity of self-efficacy items was assessed using confirmatory factor analysis (CFA). A model was considered a good fit if confirmatory factor index (CFI) > 0.95, root mean square error of approximation (RMSEA) < 0.05, and standardized root mean square residual (RMSR) < 0.05. Pearson correlations with consumption scores assessed criterion validity, and intraclass correlation coefficients (ICC) assessed test-retest reliability. RESULTS Of the eight knowledge items tested, only four items resulted in correct answers less than half of the time. CFA resulted in a 5-item scale with excellent fit indices (CFI = .99; RMSEA = .025: SRMR = .02) and Cronbach's (0.79), test-retest (ICC = 0.68), and significant correlation with intention and SSB consumption. Of the four intention items, one was significantly correlated with SSB consumption. CONCLUSIONS This study provides evidence for the validity of key constructs related to SSB consumption for use in adults, which could provide important theory-based markers for program evaluations of SSB-related interventions.
