Understanding Barriers and Enablers to State Action on Salt: Analysis of Stakeholder Perceptions of the VicHealth Salt Reduction Partnership

Salt Reduction and Iodine Fortification Policies Are Compatible: Perspectives for Public Health Advocacy

Cardiovascular diseases account for almost 18 million deaths annually, the most of all non-communicable diseases. The reduction of dietary salt consumption is a modifiable risk factor. The WHO recommends a daily sodium intake of <2000 mg but average consumption exceeds this in many countries globally. Strategies proposed to aid effective salt reduction policy include product reformulation, front of pack labelling, behavioural change campaigns and establishing a low-sodium-supportive environment. Yet, salt for household and processed food use is, in countries wholly or partially adopting a universal salt iodisation policy, the principal vehicle for population-wide iodine fortification. With salt reduction policies in place, there is concern that iodine deficiency disorders may re-emerge. Recognising the urgency to tackle the rising prevalence of NCDs yet not risk the re-emergence and detrimental effect of inadequate iodine intakes, this review lays out the feasibility of integrating both salt reduction and salt iodine fortification strategies. Reducing the burden of health risks associated with an excessive sodium intake or inadequate iodine through population-tailored, cost-effective strategies involving salt is both feasible and achievable, and represents an opportunity to improve outcomes in public health.

Fifty shades of partnerships: a governance typology for public private engagement in the nutrition sector

BACKGROUND

Multistakeholder collaboration has emerged as a dominant approach for engaging and mobilising non-state actors; notably embedded in the paradigm of the UN Sustainable Development Goals. Yet, considerable ambiguity and contestation surrounds the appropriate terms of public private engagement (PPE) with industry actors.

MAIN BODY

This paper seeks to conceptualise different forms of engagement with the food industry in tackling diet-related noncommunicable disease, within the context of power asymmetries across engaged stakeholders. It does so by introducing the Governance Typology for Public Private Engagement in the Nutrition Sector, a typology for government-led engagement with food industry actors across three domains: (i) the form of industry and civil society actor engagement (i.e., rules of exercising institutional power), based on the degree of participation in formal decision-making as well as participation at different stages in the policy cycle; (ii) the type of industry actors being engaged (i.e., pre-existing power attributes), based on function, size, and product portfolios for profit; and (iii) the substantive policy focus of engagement.

CONCLUSIONS

The Governance Typology for Public Private Engagement in the Nutrition Sector seeks to inform national level nutrition policy makers on good engagement practice with food industry actors and complements existing risk assessment tools. This typology has the potential to inform decision-making on public sector engagement with other industries that profit from products detrimental to human and planetary health.

Identifying barriers and facilitators in the development and implementation of government-led food environment policies: a systematic review

CONTEXT

Policy-specific actions to improve food environments will support healthy population diets.

OBJECTIVE

To identify cited barriers and facilitators to food environment policy (FEP) processes reported in the literature, exploring these according to the nature of the policy (voluntary or mandatory) and country development status.

DATA SOURCES

A systematic search was conducted of 10 academic and 7 grey-literature databases, national websites, and manual searches of publication references.

DATA EXTRACTION

Data on government-led FEPs, barriers, and facilitators from key informants were collected.

DATA SYNTHESIS

The constant-comparison approach generated core themes for barriers and facilitators. The appraisal tool developed by Hawker et al. was adopted to determine the quality of qualitative and quantitative studies.

RESULTS

A total of 142 eligible studies were identified. Industry resistance or disincentive was the most cited barrier in policy development. Technical challenges were most frequently a barrier for policy implementation. Frequently cited facilitators included resource availability or maximization, strategies in policy process, and stakeholder partnership or support.

CONCLUSIONS

The findings from this study will strategically inform health-reform stakeholders about key elements of public health policy processes. More evidence is required from countries with human development indices ranging from low to high and on voluntary policies.

An evaluation of the Victorian Salt Reduction Partnership's advocacy strategy for policy change

BACKGROUND

Public health advocacy strategies facilitate policy change by bringing key health issues to the forefront of public and political discourse, influencing decision-makers and public opinion, and increasing policy demand. The Victorian Salt Reduction Partnership (VSRP) was established in 2014 in response to inadequate government action to improve population diets in Australia. This study aimed to evaluate the success of the VSRP's advocacy strategy in achieving policy change.

METHODS

Documentation of VSRP activities and outputs were collected, and semi-structured interviews conducted as part of a comprehensive process evaluation. For this study, the Kotter Plus 10-step public health advocacy evaluation framework was used to guide data extraction, analysis, and synthesis.

RESULTS

A sense of urgency for salt reduction was generated by producing evidence and outlining the potential impact of a state-based salt reduction programme. This enabled the creation of a coalition with diverse skills and expertise, which facilitated the development of an innovative and collaborative advocacy action plan. A clear change vision was established, but communication of the vision to decision-makers was lacking, which reduced the impact of the programme as decision-makers were not provided with a clear incentive for policy change. As a result, while programme outputs were achieved, these did not translate to achieving broader strategic goals during a limited-term intervention in a political climate unconcerned with salt.

CONCLUSIONS

The Kotter Plus 10-step framework was a useful tool for evaluating the success of the VSRP advocacy strategy. The framework enabled the identification of key strengths, including the creation of the guiding coalition, and areas where efforts could be improved in future similar strategies, such as effective communication within partnerships and to decision-makers, to better influence policy and improve public health impact.

Stakeholder perspectives on the effectiveness of the Victorian Salt Reduction Partnership: a qualitative study

BACKGROUND

Interventions to reduce population salt intake are feasible and cost-effective. The Victorian Salt Reduction Partnership implemented a complex, multi-faceted salt reduction intervention between 2014 and 2020 in the Australian state of Victoria. This study aimed to understand stakeholder perspectives on the effectiveness of the Victorian Salt Reduction Partnership.

METHODS

Semi-structured interviews were conducted with Partnership and food industry stakeholders. The Consolidated Framework for Implementation Research was adapted for the Partnership intervention and used to guide the qualitative analysis.

RESULTS

Fourteen Partnership and seven food industry stakeholders were interviewed. The Partnership was viewed as essential for intervention planning and decision-making and an enabler for intervention delivery. The goals of capacity building and collaborative action were perceived to have been achieved. The implementation team executed intended intervention activities and outputs, with some adaptations to strategy. Barriers and enablers to implementation were identified by interviewees, such as compatibility of individual, organisational and Partnership values and building positive relationships between the Partnership and food industry, respectively. Legal, political, social, environmental, technological and economic factors affecting intervention design, delivery and outcomes were identified.

CONCLUSIONS

Establishing a Partnership with diverse skills and experience facilitated collaborative action, capacity building and execution of the intervention. Monitoring and evaluating implementation informed strategy adaptations, which allowed optimisation of Partnership strategy. The importance of developing strong communication networks between strategic and implementation-levels was a key lesson.

Unpack the Salt: an evaluation of the Victorian Salt Reduction Partnership's media advocacy activities to highlight the salt content of different foods

BACKGROUND

Australians are consuming almost double the recommended maximum salt intake. The Victorian Salt Reduction Partnership was established to coordinate efforts to reduce salt intake in the state of Victoria. As part of an intervention strategy, media advocacy strategies were used to raise public awareness and stimulate industry and government action on salt reduction. This study aimed to evaluate the Victorian Salt Reduction Partnership's media advocacy activities by determining the extent to which activities contributed to the overall strategy aims and the effectiveness of the activities in gaining media and industry engagement.

METHODS

A framework for evaluating media advocacy strategies used in complex public health interventions was used to guide this evaluation. Media advocacy activities were monitored and documented throughout the intervention period. A content analysis of media release press statements was performed. Indicators of media coverage (media items, cumulative audience reach, advertising space rate) and food industry engagement (number of meetings, number and type of follow up actions) were tracked.

RESULTS

Six media releases were issued between March 2017 and November 2018 on different processed food categories including breads, cooking sauces, ready meals, dips and crackers, processed meats and Asian-style sauces. Three main themes were identified in the qualitative analysis of the press statements: general information on salt and health, salt levels in foods, and calls to action for consumers, industry and/or government. These themes were aligned with the overall intervention strategy. Media items (print and online news, radio and TV) generated by each release ranged from 36 to 274, and cumulative audience reach (opportunities to see) ranged from 2.3 to 7.5 million Australians per release. One to three food manufacturers were met with per media release.

CONCLUSIONS

Disseminating sodium-monitoring data through media releases can be used as a tool to gain access to the media and reach consumers with salt reduction messages, and to engage food manufacturers in discussions about salt reduction. Characteristics of media advocacy activities, including alignment with the overall strategy, and external factors outside the of control of the program implementers, can influence media and industry engagement. When planning future nutrition interventions that include media advocacy activities, internal and external factors impacting outcomes, should be considered, documented and evaluated.

Salt-Related Knowledge, Attitudes and Behaviors (KABs) among Victorian Adults Following 22-Months of a Consumer Awareness Campaign

The Australian population consumes more salt than recommended and this increases the risk of raised blood pressure and cardiovascular disease. In 2015, a state-wide initiative was launched in the Australian state of Victoria to reduce population salt intake. This study examines whether salt-related knowledge, attitudes and behaviors (KABs) of Victorian adults changed following the first 22 months of a consumer awareness campaign targeting parents. Repeated cross-sectional surveys of adults (18–65 years) recruited from research panels. Analyses were weighted to reflect the Victorian population. In both surveys mean age of participants (1584 in 2015 and 2141 in 2018) was 41 years, and 51% were female. This includes 554 parents/caregivers in 2015 and 799 in 2018. Most indicators of KAB remained unchanged. Among parents/caregivers the percentage who agreed limiting salt in their child’s diet was important increased by 8% (p = 0.001), and there was a 10% reduction in the percentage who reported placing a saltshaker on the table and a 9% reduction in those who reported their child added salt at the table (both p < 0.001). Some small adverse effects on other indicators were also observed. During the first 22 months of a salt reduction consumer awareness campaign, there were limited changes in KAB overall, however the target audience reported positive changes regarding their children, which aligned with the campaign messages.
