Changes in sodium levels in Australian packaged foods between 2014 and 2019: an interrupted time series analysis of the impact of the Victorian Salt Reduction Partnership's media advocacy strategy.

BACKGROUND: The Victorian Salt Reduction Partnership (VSRP) implemented a media advocacy strategy (intervention) to stimulate food manufacturers to reduce sodium levels across targeted Australian packaged foods between 2017 and 2019. This study assessed changes in sodium levels of targeted and non-targeted packaged foods during the intervention (2017 to 2019) compared to before the intervention (2014 to 2016) in Australia. METHODS: Annually collected branded-food composition data from 2014 to 2019 were used. Interrupted time series analyses was conducted to compare the trend in sodium levels in packaged foods during the intervention (2017-2019) to the trend in the pre-intervention period (2014-2016). The difference between these trends was derived to estimate the effect of the intervention. RESULTS: A total of 90,807 products were included in the analysis, of which 14,743 were targeted by the intervention. The difference in before and during intervention trends between targeted and non-targeted food categories was 2.59 mg/100 g (95% CI: -13.88 to 19.06). There was a difference in the pre-intervention slope (2014, 2015, 2016) and intervention slope (2017, 2018, 2019) for four of 17 targeted food categories. There was a decrease in sodium levels (mg/100 g) in one food category: frozen ready meals (-13.47; 95% CI: -25.40 to -1.53), and an increase in three categories: flat bread (20.46; 95% CI: 9.11 to 31.81), plain dry biscuits (24.53; 95% CI: 5.87 to 43.19), and bacon (44.54; 95% CI: 6.36 to 82.72). For the other 13 targeted categories, the difference in slopes crossed the line of null effect. CONCLUSIONS: The VSRP's media advocacy strategy did not result in a meaningful reduction in sodium levels of targeted packaged food products during the intervention years compared to trends in sodium levels before the intervention. Our study suggests media advocacy activities highlighting the differences in sodium levels in packaged food products and industry meetings alone are not sufficient to lower average sodium levels in packaged foods in the absence of government leadership and measurable sodium targets.

Outcomes of a state-wide salt reduction initiative in adults living in Victoria, Australia.

PURPOSE: To assess any effects of a state-wide sodium reduction intervention on sodium intake, sources of dietary sodium and discretionary salt use at a population level. METHODS: Data (24-h urinary sodium excretion, self-report survey, a 24-h dietary recall) were collected cross-sectionally at baseline (2016/2017) and follow-up (2020) from adults in Victoria, Australia. Intervention activities included consumer awareness advertising campaign, public debate generation via mass media, strengthening existing policy initiatives and supporting food innovation with industry. RESULTS: There were 339 participants at baseline and 211 at follow-up, with 144 and 90 of participants completing a 24-h dietary recall, respectively. There was no difference in adjusted 24-h urinary sodium excretion between baseline and follow-up (134 vs 131 mmol/24 h; p = 0.260). There were no differences in the percentage of participants adding salt during cooking (63% vs 68%; p = 0.244), adding salt at the table (34% vs 37%; p = 0.400) or regularly taking action to control salt/sodium intake (22% vs 21%; p = 0.793). There were large differences in the quantity of dietary sodium sourced from retail stores (57% vs 77%, p < 0.001), and less sodium was sourced from foods at fresh food markets (13% vs 2%; p ≤ 0.001) at follow-up. No large differences were apparent for foods with different levels of processing or for food groups. CONCLUSION: There was no clear population-level effect of the 4-year multi-component Victorian Salt Reduction Intervention on sodium intake with Victorian adults continuing to consume sodium above recommended levels. The findings indicate that more intensive and sustained efforts aiming at the retail and food industry with national level support are likely to be required to achieve a measurable improvement in sodium intake at a state level.

Evaluation of a state-wide intervention on salt intake in primary schoolchildren living in Victoria, Australia.

OBJECTIVE: In 2015, the Victorian Salt Reduction Partnership launched a 4-year multifaceted salt reduction intervention designed to reduce salt intake by 1 g/d in children and adults living in Victoria, Australia. Child-relevant intervention strategies included a consumer awareness campaign targeting parents and food industry engagement seeking to reduce salt levels in processed foods. This study aimed to assess trends in salt intake, dietary sources of salt and discretionary salt use in primary schoolchildren pre- and post-delivery of the intervention. DESIGN: Repeated cross-sectional surveys were completed at baseline (2010-2013) and follow-up (2018-2019). Salt intake was measured via 24-h urinary Na excretion, discretionary salt use behaviours by self-report and sources of salt by 24-h dietary recall. Data were analysed with multivariable-adjusted regression models. SETTING: Victoria, Australia. PARTICIPANTS: Children aged 4-12 years. RESULTS: Complete 24-h urine samples were collected from 666 children at baseline and 161 at follow-up. Mean salt intake remained unchanged from baseline (6·0; se 0·1 g/d) to follow-up (6·1; 0·4 g/d) (P = 0·36), and there were no clear differences in the food sources of salt and at both time points approximately 70 % of children exceeded Na intake recommendations. At follow-up, 14 % more parents (P = 0·001) reported adding salt during cooking, but child use of table salt and inclusion of a saltshaker on the table remained unchanged. CONCLUSION: These findings show no beneficial effect of the Victorian Salt Reduction Partnership intervention on children's salt intake. More intensive, sustained and coordinated efforts between state and federal stakeholders are required.

Agreement between 24-hour urine and 24-hour food recall in measuring salt intake in primary school children in Australia.

BACKGROUND: Monitoring salt consumption in children is essential for informing and implementing public health interventions to reduce children's salt intake. However, collection of 24-hour urines, considered as the most reliable approach, can be especially challenging to school children. This study aimed to assess the agreement between 24-hour urine (24hrU) and 24-hour food recall (24hrFR) in: (1) estimating salt intake in children; (2) classifying salt intakes above the recommended upper level set for children, and; (3) estimating change in mean salt intake over time. METHODS: This study utilised data from two cross-sectional surveys of school children aged 8 to 12 years living in the state of Victoria, Australia. A single 24hrU and 24hrFR were collected from each participant. Suspected inaccurate urine collections and implausible energy intakes were excluded based on pre-defined criteria. The agreement between the two methods was assessed using Bland-Altman methodology, the intraclass correlation coefficient (ICC), and the kappa statistic. The difference between the measured change in salt intake over time using 24hrU and 24hrFR was derived using mixed effects linear regression analysis. RESULTS: A total of 588 participants provided a 24hrU and 24hrFR. Overall, there was no meaningful difference in mean estimated salt intake between the two methods (- 0.2 g/day, 95% CI - 0.5 to 0.1). The Bland-Altman plot showed wide 95% limits of agreement (- 7.2 to 6.8). The ICC between the two methods was 0.13 (95% CI 0.05 to 0.21). There was poor interrater reliability in terms of classifying salt intake above the recommended upper level for children, with an observed agreement of 63% and kappa statistic of 0.11. The change in mean salt intake over time was 0.2 g/day (- 0.4 to 0.7) based on 24hrU, and 0.5 g/day (- 0.0 to 1.1) based on 24hrFR, with a difference-in-differences of 0.4 g/day (- 0.3 to 1.1). CONCLUSIONS: 24hrFR appears to provide a reasonable estimate of mean salt intake as measured by 24hrU in Australian school children. However, similar to previous observations in adults, and of studies exploring other alternative methods for estimating salt intake, 24hrFR is a poor predictor of individual-level salt intake in children.

Implementing effective salt reduction programs and policies in low- and middle-income countries: learning from retrospective policy analysis in Argentina, Mongolia, South Africa and Vietnam.

OBJECTIVE: To understand the factors influencing the implementation of salt reduction interventions in low- and middle-income countries (LMIC). DESIGN: Retrospective policy analysis based on desk reviews of existing reports and semi-structured stakeholder interviews in four countries, using Walt and Gilson's 'Health Policy Triangle' to assess the role of context, content, process and actors on the implementation of salt policy. SETTING: Argentina, Mongolia, South Africa and Vietnam. PARTICIPANTS: Representatives from government, non-government, health, research and food industry organisations with the potential to influence salt reduction programmes. RESULTS: Global targets and regional consultations were viewed as important drivers of salt reduction interventions in Mongolia and Vietnam in contrast to local research and advocacy, and support from international experts, in Argentina and South Africa. All countries had population-level targets and written strategies with multiple interventions to reduce salt consumption. Engaging industry to reduce salt in foods was a priority in all countries: Mongolia and Vietnam were establishing voluntary programs, while Argentina and South Africa opted for legislation on salt levels in foods. Ministries of Health, the WHO and researchers were identified as critical players in all countries. Lack of funding and technical capacity/support, absence of reliable local data and changes in leadership were identified as barriers to effective implementation. No country had a comprehensive approach to surveillance or regulation for labelling, and mixed views were expressed about the potential benefits of low sodium salts. CONCLUSIONS: Effective scale-up of salt reduction programs in LMIC requires: (1) reliable local data about the main sources of salt; (2) collaborative multi-sectoral implementation; (3) stronger government leadership and regulatory processes and (4) adequate resources for implementation and monitoring.

Are there socio-demographic differences in salt behaviours and fruit and vegetable consumption in Australian adults? A nationally representative cross-sectional survey.

BACKGROUND: Diets low in fruit and vegetables and high in salt are among the top dietary risk factors for non-communicable diseases (NCDs). Using a nationally representative sample of Australians, this study aimed to describe self-reported intake of fruit and vegetables, and knowledge, attitudes and behaviours related to salt intake, and determine if there were socio-demographic differences between population subgroups. METHODS: A 2016 cross-sectional survey of Australian adults aged 18 years and over, which comprised 160 questions, including socio-demographic and health-related questions. Descriptive statistics (mean, 95% confidence interval, %) were calculated. Weighted-adjusted logistic regression models were used to determine if there were socio-demographic differences in salt behaviours and fruit and vegetable consumption. RESULTS: A total of 1217 participants completed the survey (51% female). Less than 8% of participants reported consuming the recommended 2 or more serves of fruit and 5 or more serves of vegetables. Almost 60% of participants frequently added salt during cooking/meal preparation and 42% of respondents frequently placed a salt-shaker on the table at mealtimes. There were no consistent patterns between socio-demographic factors and measures of fruit and vegetable consumption and salt behaviours. Differences in at least one measure were found for sex, age, location, education level and weight category. CONCLUSIONS: There were no consistent patterns between socio-demographic factors and salt behaviours and fruit and vegetable intake. Less than recommended intakes of fruit and vegetables and frequent discretionary salt use are placing Australians at risk of diet-related NCDs. Broad population-based policies and programs to improve fruit and vegetable intake and salt behaviours are needed to improve Australian's diets.

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.

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.

A comprehensive overview and qualitative analysis of government-led nutrition policies in Australian institutions.

BACKGROUND: Institutions are a recommended setting for dietary interventions and nutrition policies as these provide an opportunity to improve health by creating healthy food environments. In Australia, state and territory governments encourage or mandate institutions in their jurisdiction to adopt nutrition policies. However, no work has analysed the policy design across settings and jurisdictions. This study aimed to compare the design and components of government-led institutional nutrition policies between Australian states and territories, determine gaps in existing policies, and assess the potential for developing stronger, more comprehensive policies. METHODS: Government-led institutional nutrition policies, in schools, workplaces, health facilities and other public settings, were identified by searching health and education department websites for each Australian state and territory government. This was supplemented by data from other relevant stakeholder websites and from the Food Policy Index Australia website. A framework for monitoring and evaluating nutrition policies in publicly-funded institutions was used to extract data and a qualitative analysis of the design and content of institutional nutrition policies was performed. Comparative analyses between the jurisdictions and institution types were conducted, and policies were assessed for comprehensiveness. RESULTS: Twenty-seven institutional nutrition policies were identified across eight states and territories in Australia. Most policies in health facilities and public schools were mandatory, though most workplace policies were voluntary. Twenty-four included nutrient criteria, and 22 included guidelines for catering/fundraising/advertising. While most included implementation guides or tools and additional supporting resources, less than half included tools/timelines for monitoring and evaluation. The policy design, components and nutrient criteria varied between jurisdictions and institution types, though all were based on the Australian Dietary Guidelines. CONCLUSIONS: Nutrition policies in institutions present an opportunity to create healthy eating environments and improve population health in Australia. However, the design of these policies, including lack of key components such as accountability mechanisms, and jurisdictional differences, may be a barrier to implementation and prevent the policies having their intended impact.

Estimating mean population salt intake in Fiji and Samoa using spot urine samples.

BACKGROUND: There is an increasing interest in finding less costly and burdensome alternatives to measuring population-level salt intake than 24-h urine collection, such as spot urine samples. However, little is known about their usefulness in developing countries like Fiji and Samoa. The purpose of this study was to evaluate the capacity of spot urine samples to estimate mean population salt intake in Fiji and Samoa. METHODS: The study involved secondary analyses of urine data from cross-sectional surveys conducted in Fiji and Samoa between 2012 and 2016. Mean salt intake was estimated from spot urine samples using six equations, and compared with the measured salt intake from 24-h urine samples. Differences and agreement between the two methods were examined through paired samples t-test, intraclass correlation coefficient analysis, and Bland-Altman plots and analyses. RESULTS: A total of 414 participants from Fiji and 725 participants from Samoa were included. Unweighted mean salt intake based on 24-h urine collection was 10.58 g/day (95% CI 9.95 to 11.22) in Fiji and 7.09 g/day (95% CI 6.83 to 7.36) in Samoa. In both samples, the INTERSALT equation with potassium produced the closest salt intake estimate to the 24-h urine (difference of - 0.92 g/day, 95% CI - 1.67 to - 0.18 in the Fiji sample and + 1.53 g/day, 95% CI 1.28 to 1.77 in the Samoa sample). The presence of proportional bias was evident for all equations except for the Kawasaki equation. CONCLUSION: These data suggest that additional studies where both 24-h urine and spot urine samples are collected are needed to further assess whether methods based on spot urine samples can be confidently used to estimate mean population salt intake in Fiji and Samoa.

Food intake in an Australian Aboriginal rural community facing food and water security challenges: A cross-sectional survey.

AIMS: Researchers were invited by Aboriginal leaders to collaborate on this study which aimed to assess food intake in the Walgett Aboriginal community to inform long-term community-led efforts to improve food and water security and nutrition. METHODS: Aboriginal adults living in or near Walgett, a remote community in north-west NSW, Australia, completed an adapted Menzies Remote Short-item Dietary Assessment Tool, which was administered verbally and face-to-face in early 2022. Aboriginal people were involved in the survey design, training and collection, and analysis of data. Descriptive statistics were tabulated, overall and by gender, age, and location. Differences by sex, age group (18-44 years versus ≥45 years), and location (Walgett town or other) were determined using a chi-square test. RESULTS: A total of 242 participants completed the survey; 55% were female. Three-quarters of participants reported meeting the recommendations for discretionary foods (73%); however, more than half (56%) exceeded the recommended maximum serves of sugar-sweetened beverages. The proportion of participants meeting core food group guidelines was 72% for meat, 36% for fruit, 20% for bread and cereals, 6% for dairy, and 3% for vegetables. Overall, none of the participants met the recommended serves of all food groups outlined in the Australian Dietary Guidelines. CONCLUSION: Findings show that Walgett Aboriginal community members surveyed were consuming a healthier diet than national data reported for Aboriginal and Torres Strait Islander people in Australia. However, none of the participants were meeting all of the national dietary guidelines, placing them at increased risk of diet-related chronic disease. Local Aboriginal community-led efforts to improve food and water security should include specific strategies to improve nutrition.

The nutritional profile of plant-based meat analogues available for sale in Australia.

AIM: To assess the nutritional quality of plant-based meat analogues in Australia, compared to equivalent meat products, and to assess levels of micronutrient fortification in meat analogues. METHODS: This cross-sectional study used nutrition composition data for products collected in 2021 from major supermarkets in Australia. Nutritional quality was assessed using the Health Star Rating, energy (kJ), protein (g), saturated fat (g), sodium (mg), total sugars (g), and fibre content (g) per 100 g, and level of food processing using the NOVA classification. Proportion of products fortified with iron, vitamin B12 and zinc were reported. Differences in health star rating and nutrients between food categories were assessed using independent t-tests. RESULTS: Seven hundred ninety products (n = 132 plant-based and n = 658 meat) across eight food categories were analysed. Meat analogues had a higher health star rating (mean 1.2 stars, [95% CI: 1.0-1.4 stars], p < 0.001), lower mean saturated fat (-2.4 g/100 g, [-2.9 to -1.8 g/100 g], p < 0.001) and sodium content (-132 mg/100 g, [-186 to -79 mg/100 g], p < 0.001), but higher total sugar content (0.7 g/100 g, [0.4-1.1 g/100 g], p < 0.001). Meat analogues and meat products had a similar proportion of ultra-processed products (84% and 89%, respectively). 12.1% of meat analogues were fortified with iron, vitamin B12 and zinc. CONCLUSION: Meat analogues generally had a higher health star rating compared with meat equivalents, however, the nutrient content varied. Most meat analogues were also ultra-processed and few are fortified with key micronutrients found in meat. More research is needed to understand the health impact of these foods.

Estimated Dietary and Health Impact of the World Health Organization's Global Sodium Benchmarks on Packaged Foods in Australia: a Modeling Study.

BACKGROUND: In 2021, the World Health Organization (WHO) set sodium benchmarks for packaged foods to guide countries in setting feasible and effective sodium reformulation programs. We modeled the dietary and health impact of full compliance with the WHO's sodium benchmarks in Australia and compared it to the potential impact of Australia's 2020 sodium reformulation targets. METHODS: We used nationally representative data on food and sodium intake, sodium levels in packaged foods, and food sales volume to estimate sodium intake pre- and post-implementation of the WHO and Australia's sodium benchmarks for 24 age-sex groups. Using comparative risk assessment models, we then estimated the potential deaths, incidence, and disability-adjusted life years averted from cardiovascular disease, chronic kidney disease, and stomach cancer based on the reductions in sodium intake. RESULTS: Compliance with the WHO's sodium benchmarks for packaged foods in Australia could lower mean adult sodium intake by 404 mg/day, corresponding to a 12% reduction. This could prevent about 1770 deaths/year (95% uncertainty interval 1168-2587), corresponding to 3% of all cardiovascular disease, chronic kidney disease, and stomach cancer deaths in Australia, and prevent some 6900 (4603-9513) new cases, and 25 700 (17 655-35 796) disability-adjusted life years/year. Compared with Australian targets, the WHO benchmarks will avert around 3 and a half times more deaths each year (1770 versus 510). CONCLUSIONS: Substantially greater health impact could be achieved if the Australian government strengthened its current sodium reformulation program by adopting WHO's more stringent and comprehensive sodium benchmarks.

Do Food and Nutrition Policies in Ethiopia Support the Prevention of Non-Communicable Diseases through Population-Level Salt Reduction Measures? A Policy Content Analysis.

INTRODUCTION: Despite the importance of salt reduction to health outcomes, relevant policy adoption in Ethiopia has been slow, and dietary consumption of sodium remains relatively high. AIM: This analysis aims to understand the content and context of existing food-related policy, strategy, and guideline documents to identify gaps and potential opportunities for salt reduction in Ethiopia in the wider context of global evidence-informed best practice nutrition policy. METHODS: Policy documents relevant to food and noncommunicable diseases (NCDs), published between 2010 and December 2021, were identified through searches of government websites supplemented with experts' advice. Documentary analysis was conducted drawing on the 'policy cube' which incorporates three dimensions: (i) comprehensiveness of policy measures, which for this study included the extent to which the policy addressed the food-related WHO "Best Buys" for the prevention of NCDs; (ii) policy salience and implementation potential; and (iii) equity (including gender) and human rights orientation. RESULTS: Thirty-two policy documents were retrieved from government ministries, of which 18 were deemed eligible for inclusion. A quarter of these documents address diet-related "Best Buys" through the promotion of healthy nutrition and decreasing consumption of excess sodium, sugar, saturated fat, and trans-fats. The remainder focuses on maternal and child health and micronutrient deficiencies. All documents lack detail relating to budget, monitoring and evaluation, equity, and rights. CONCLUSIONS: This review demonstrates that the Government of Ethiopia has established policy frameworks highlighting its intention to address NCDs, but that there is an opportunity to strengthen these frameworks to improve the implementation of salt reduction programs. This includes a more holistic approach, enhanced clarification of implementation responsibilities, stipulation of budgetary allocations, and promoting a greater focus on inequities in exposure to nutrition interventions across population groups. While the analysis has identified gaps in the policy frameworks, further qualitative research is needed to understand why these gaps exist and to identify ways to fill these gaps.

Review of national nutrition standards with salt-related criteria for publicly funded institutions around the world.

CONTEXT: Creating healthy food environments through nutrition standards for publicly funded institutions (eg, schools, workplaces, and hospitals) provides an important opportunity to improve population diets. OBJECTIVE: This study aimed to identify countries with national nutrition standards for publicly funded institutions that included salt-related criteria and to describe and summarize these initiatives. DATA SOURCES: Peer-reviewed and grey literature was searched to December 2019, including MEDLINE, CENTRAL, Embase, TRoPHI, LILACS, Web of Science, Cochrane Public Health Group Specialised Register, and Effective Public Health Practice Project Database. In addition, a questionnaire was sent to country contacts and salt-reduction experts, and a targeted search on relevant government websites was conducted. DATA EXTRACTION: Key characteristics of the national nutrition standards for publicly funded institutions were extracted, including name, governance, institution type, implementation status, and details of food and nutrient criteria. DATA ANALYSIS: Nutrition standards were analyzed by World Health Organization region, World Bank income level, institution type, type of criteria, regulatory approach, and method of application. Sixty-six countries were identified as having national nutrition standards that included salt-related criteria for at least one publicly funded institution. Standards were more prevalent in the European Region, high-income countries, and schools compared to other regions, income levels, and institution types, respectively. Most standards were mandatory and contained nutrition criteria pertaining to both foods and nutrients. CONCLUSION: Nutrition standards have the potential to significantly improve diets, but there is considerable scope to develop and implement nutrition standards more effectively using the new World Health Organization Action Framework.

Setting sodium targets for pre-packaged foods in China - an exploratory study.

Introduction: Setting sodium targets for pre-packaged food has been a priority strategy for reducing population sodium intake. This study aims to explore the attitudes and considerations of researchers and key stakeholders toward implementing such policy in China. Methods: An exploratory study comprising a survey and a focus group discussion was conducted among 27 purposively selected participants including 12 researchers, 5 consumers, 4 administrators, 3 industry association representatives and 3 food producers. The survey/discussion covered the key questions considered when developing/promoting sodium targets. Free-text responses were manually classified and summarized using thematic analysis. Results: Two-thirds of the participants supported target-setting policy. Researchers and administrators were most supportive, and food producers and associations were least supportive. Adapted WHO food categorization framework was well accepted to underpin target-setting to ensure international comparability and applicability for Chinese products. Maximum values were the most agreed target type. The WHO benchmarks were thought to be too ambitious to be feasible given the current food supply in China but can be regarded as long-term goals. Initially, a reduction of sodium content by 20% was mostly accepted to guide the development of maximum targets. Other recommendations included implementing a comprehensive strategy, strengthening research, engaging social resources, establishing a systematic monitoring/incentive system, maintaining a fair competitive environment, and developing a supportive information system. Target-setting policy was acceptable by most stakeholders and should be implemented alongside strategies to reduce discretionary salt use. Discussion: Our findings provide detailed guidance for the Chinese government when developing a target-setting strategy. The methods and results of this study also provide meaningful references for other countries to set sodium targets for pre-packaged foods and implement other salt reduction strategies simultaneously.

Evaluation of a Salt-Reduction Consumer Awareness Campaign Targeted at Parents Residing in the State of Victoria, Australia.

From 2015 to 2020 a state-wide salt-reduction initiative was launched in Victoria, Australia, including an awareness campaign focused on parents with children <18 years of age. To evaluate the impact of the campaign on salt-related knowledge, attitudes and behaviors (KABs) we have assessed trends in salt-related KAB pre- and post-delivery of the campaign in parents, as well as within the wider adult population. Cross-sectional surveys of adults aged 18-65 years were undertaken pre- (2015: n = 821 parents; n = 1527 general sample) and post-campaign (2019: n = 935 parents; n = 1747 general sample). KABs were assessed via an online survey. Data were analyzed with regression models and adjusted for covariates. Among parents, around one-quarter of salt-related KABs shifted in a positive direction, but changes were small: there was a 6% (95% CI 2, 11%) increase in the percentage who knew the main source of salt in the diet and reductions in the percentage who reported placing a salt shaker on the table (-8% (95%CI -12, -3)) and that their child added salt at the table (-5% (95% -9, -0.2)). Among the wider adult sample, even fewer shifts in KAB were observed, with some behaviors worsening at follow-up. These findings indicate that this consumer awareness campaign had minimum impact.

Australian Ready Meals: Does a Higher Health Star Rating Mean Lower Sodium Content?

Ready meals are typically a high sodium product and excessive sodium increases the risk for chronic disease. The study aimed to explore the association between sodium content, Health Star Rating (HSR) and the Healthy Food Partnership (HFP) sodium reduction target for ready meals. Median (IQR) sodium content in mg/100 g and mg/serving were determined overall and for each subcategory (ambient, chilled and frozen). Wilcoxon rank sum test was used to compare the sodium content between ready meals with and without HSR. The Jonckheere trend test was used to assess presence of trend in sodium content by HSR categories. In total, 631 ready meals were included and 311 (49%) met the HFP sodium target (<250 mg per 100 g). The percentage of products displaying the voluntary front-of-pack HSR was 52% and of these, 82% had a star rating ≥3.5. A lower median sodium content (mg/100 g) was consistently observed for products with HSR compared with products without HSR (all p's < 0.05). Except for ambient ready meals, a trend was observed where the higher the HSR category, the lower the sodium content (p < 0.001). A higher proportion of the products with HSR ≥ 4 met the HFP sodium target for ready meals.

Understanding Enablers and Barriers to the Implementation of Nutrition Standards in Publicly Funded Institutions in Victoria.

Effective implementation of nutrition standards in publicly funded institutions can facilitate healthy food and beverage consumption by communities and populations, which can enable improvements in dietary intake and reduce disease burden. This study aimed to understand stakeholder perspectives on the implementation of government nutrition standards in publicly funded institutions in the Australian state of Victoria, as well as to determine enablers and barriers to successful implementation. Pre-interview questionnaires and semi-structured interviews were administered to stakeholders involved in the implementation of nutrition standards in publicly funded institutions in Victoria. The Interactive Systems Framework, which allows understanding of the infrastructure and systems needed to implement policies, was used to design the survey instruments and guide the data analysis. Forty-four stakeholders were interviewed, including program implementers, support personnel and food providers, across public sector hospitals and health services, workplaces, sport and recreation centres and schools. Though translated materials and resources have been developed for end-users to facilitate uptake and implementation, current nutrition standards were perceived to be long and complex, which hindered implementation. The existence of a government-funded implementation support service enabled action by providing technical support, troubleshooting and capacity-building. A specific pathway for successful guideline implementation was determined through the analysis. Opportunities to close the policy-implementation gap were identified. This will be crucial to maximising the impact of nutrition standards on population diets and reducing diet-related disease. Strengthening the guidelines and their governance, streamlining the support system and overcoming barriers within and outside of implementing organisations, are urgently required to propel statewide progress.

Advancing Health Research Impact through a Systemic Multi-Sectoral Approach: A Protocol for Introducing Reduced-Sodium Salts and Salty Condiments in Vietnam.

Better alignment between health research organisations with the needs (and interests) of key stakeholders in the health policy and research system is critical to improving research impact. The George Institute for Global Health's 'Healthier Societies' program focuses on harnessing the power of governments, markets, and communities to improve population level health equity outcomes and maximise research impact. This protocol outlines a systemic multi-sectoral approach to advance health research impact globally applied to a project to reduce population salt intake in Vietnam by introducing reduced-sodium salts and salty condiments. We defined a systemic multi-sectoral approach to be a strategy that involves engaging with government, market and communities in a deliberate and joined-up way to solve a problem in which they all have a role to play. The project objectives are to: (i) produce reduced-sodium fish sauce products and test consumer acceptability; (ii) investigate the market feasibility of introducing reduced-sodium foods (salt, bot canh and fish sauce) into the Vietnamese market; (iii) estimate the cost-effectiveness of three different government strategies to support the implementation of reduced-sodium products; and (iv) develop an advocacy roadmap to maximise potential research impact. Methods will include standard quality and safety assessments, consumer sensory testing for the locally produced reduced-sodium fish sauces, market feasibility assessment (including collating market data and semi-structured interviews with stakeholders), cost-effectiveness modelling (Markov cohort model), multi-sector stakeholder engagement, and the development of a coordinated advocacy strategy using the Kotter Plus framework. Health research organisations are increasingly seeking ways to achieve greater impact with their research. Through the application of a systemic multi-sectoral approach with governments, markets and communities, this protocol provides an example of how health research projects can achieve such impact.
