In Fiji, packaged foods are becoming increasingly available. However, it is unknown if nutrition composition of these foods has changed. This study aims to assess changes in energy, nutrient content and healthiness of packaged foods by comparing data from five major supermarkets in Fiji in 2018 and 2020. Foods were categorised into 14 groups; nutrient composition information was extracted and healthiness assessed using Health Star Rating (HSR). Descriptive statistics and a separate matched products analysis was conducted summarising differences in nutrient content and HSR. There was limited evidence of change in the nutrient content of included products however, there was a small reduction in mean saturated fat in the snack food category (-1.0 g/100 g, 95% CI -1.6 to -0.4 g/100 g). The proportion of products considered healthy based on HSR, increased in the convenience foods category (28.4%, 95% CI 8.3 to 48.5) and decreased in non-alcoholic beverages (-35.2%, 95% CI -43.6 to -26.9). The mean HSR score increased in the fruit and vegetables category (0.1 (95% CI 0.1, 0.2)) and decreased for non-alcoholic beverages (-1.1 (-1.3, -0.9)) and the sauces, dressings, spreads, and dips category (-0.3 (-0.3, -0.2)). Strengthened monitoring of the food supply is needed to improve the healthiness of foods available.

Background: Excess salt and sugar consumption contribute to diseases, such as diabetes and hypertension. This study aimed to estimate salt and sugar intakes and main sources, in a population of adults in the Central Division of Fiji. Methods: One adult per household was randomly selected to participate (n = 700). Sociodemographic characteristics; blood pressure, weight, and height; a 24-h diet recall; and spot-urine samples were collected, with 24-h urine samples from a sub-sample (n = 200). Sugar intake was estimated from the 24-h diet recalls and salt intake from the spot-urines. 24-hr diet recall was used to identify main sources of salt and sugar by food groups. Findings: 534 adults (response rate 76%, 50% women, mean age 42 years) participated. Salt intake was 8.8 g/day (95% CI, 8.7-9.0), and free sugar intake was 74.1 g/day (67.5-80.7), 16.1% of total energy intake (15.0-17.1%). Main sources of salt were mixed cooked dishes (40.9% (38.2-43.5)), and bread and bakery products (28.7% (26.5-31.0)). Main sources of sugar were table sugars, honey, and related products (24.3% (21.7-26.8)), non-alcoholic beverages (21.4% (18.8-24.0)) and bread and bakery products (18.0% (16.2-19.9)). Interpretation: Salt and sugar intakes exceeded World Health Organization recommendations in this sample of adults. Given dietary sources were foods high in salt and sugar, along with the addition to food or drinks, interventions focused on behavior along with environmental strategies to encourage healthier choices are needed.

OBJECTIVE: To understand the extent to which national salt reduction strategies in Malaysia and Mongolia were implemented and achieving their intended outcomes. DESIGN: Multiple methods process evaluations conducted at the mid-point of strategy implementation, guided by theoretical frameworks. SETTING: Malaysia (2018-2019) and Mongolia (2020-2021). PARTICIPANTS: Desk-based reviews of related documents, interviews with key stakeholders (n 12 Malaysia, n 10 Mongolia), focus group discussions with health professionals in Malaysia (n 43) and health provider surveys in Mongolia (n 12). RESULTS: Both countries generated high-quality local evidence about salt intake and levels in foods and culturally specific education resources. In Malaysia, education and reformulation activities were delivered with moderate dose (quantity) but reach among the population was low. Within 5 years, Mongolia implemented education among schools, health professionals and food producers on salt reduction with high reach, but with moderate dose (quantity) and reach among the general population. Both countries faced challenges in implementing legislative interventions (mandatory salt labelling and salt limits in packaged foods) and both could improve the scaling up of their reformulation and education activities. CONCLUSIONS: In the first half of Malaysia's and Mongolia's strategies, both countries generated necessary evidence and education materials, mobilised health professionals to deliver salt reduction education and achieved small-scale reformulation in foods. Both subsequently should focus on implementing regulatory policies and achieving population-wide reach and impact. Process evaluations of existing salt reduction strategies can help strengthen intervention delivery, aiding achievement of WHO's 30 % reduction in salt intake by 2025 target.

BACKGROUND: Understanding health behaviour changes during the COVID-19 pandemic can assist in developing strategies to promote healthy lifestyles at such times. The aim of this exploratory study was to examine whether the frequency of consuming unhealthy foods and beverages changed during lockdown and whether certain population subgroups were more likely to make such changes. METHOD: An online survey was administered to a national sample of 4022 Australian adults (51% female, mean age 48 years). Generalised linear models with generalised estimating equations were used to identify whether demographic characteristics (age, gender, education, presence of children in the household, number of people in the household) and beliefs related to COVID-19 were associated with changes in the frequency of consuming alcohol, sweet snacks, salty snacks, and sugary beverages from pre to during lockdown. RESULTS: Overall, the frequency of consuming the four assessed unhealthy products did not change during lockdown. However, being male and having children at home were consistently associated with unhealthy changes, whereas believing that alcohol or unhealthy diets would exacerbate COVID-19 severity was linked to a decreased frequency of consuming these products respectively. Age, education, and living with more people were also associated with changes in the frequency of consuming some product categories. CONCLUSION: During lockdown, certain population subgroups appeared to be at increased risk of more frequent consumption of unhealthy foods and beverages. Believing certain consumption habits are linked to adverse health impacts of COVID was found to reduce frequency of consumption of related products, presenting a potential focus for future public health actions.

The VALID BP project was initiated to increase the availability of validated blood pressure measuring devices (BPMDs). The goal is to eliminate non validated BPMDs and minimise over- and underdiagnosis of hypertension caused by inaccurate readings. This study was undertaken to assess the potential return on investment in the VALID BP project. The Framework to Assess the Impact of Translational Health Research was applied to the VALID BP project. This paper focuses on the implementation of the cost benefit analysis aspect of this framework to monetise past research investment and model future research costs, implementation costs, and benefits. Analysis was based on reasoned assumptions about potential impacts from availability and use of validated BPMDs (assuming an end goal of 100% validated BPMDs available in Australia by 2028) and improved skills leading to more accurate BP measurement. After 5 years, with 20% attribution of benefits, there is a potential $1.14-$1.30 return for every dollar spent if the proportion of validated BPMDs and staff trained in proper BP measurement technique increased from 20% to 60%. After eight years (2020-2028) and assuming universal validation and training coverage, the returns would be between $2.70 and $3.20 per dollar spent (not including cost of side effects of unnecessary medication or downstream patient impacts from unmanaged hypertension). This modelled economic analysis indicates there will be positive downstream economic benefits if the availability of validated BPMDs is increased. The findings support ongoing efforts toward a universal regulatory framework for BPMDs and can be considered within more detailed future economic analyses.

INTRODUCTION: Food insecurity is associated with inadequate nutrition and increased rates of chronic disease. The primary aim of this study was to assess self-reported food insecurity and the perceived impact of COVID-19 on food security, in two regional districts of Central Fiji, as part of a broader program of work on strengthening and monitoring food policy interventions. The secondary aim was to explore the relationship between food insecurity and salt, sugar and fruit and vegetable intake. METHODS: Seven hundred adults were randomly sampled from the Deuba and Waidamudamu districts of Viti Levu, Fiji. Interview administered surveys were conducted by trained research assistants with data collected electronically. Information was collected on demographics and health status, food security, the perceived impact of COVID-19 on food security, and dietary intake. Food insecurity was assessed using nine questions adapted from Fiji's 2014/5 national nutrition survey, measuring markers of food insecurity over the last 12 months. Additional questions were added to assess the perceived effect of COVID-19 on responses. To address the secondary aim, interview administered 24-hour diet recalls were conducted using Intake24 (a computerised dietary recall system) allowing the calculation of salt, sugar and fruit and vegetable intakes for each person. Weighted linear regression models were used to determine the relationship between food insecurity and salt, sugar and fruit and vegetable intake. RESULTS: 534 people participated in the survey (response rate 76%, 50.4% female, mean age 42 years). 75% (75.3%, 95% CI, 71.4 to 78.8%) of people reported experiencing food insecurity in the 12 months prior to the survey. Around one fifth of people reported running out of foods (16.8%, 13.9 to 20.2%), having to skip meals (19.3%, 16.2 to 22.9%), limiting variety of foods (19.0%, 15.9 to 22.5%), or feeling stressed due to lack of ability to meet food needs (19.5%, 16.4 to 23.0%). 67% (66.9%, 62.9 to 70.7%) reported becoming more food insecure and changing what they ate due to COVID-19. However, people also reported positive changes such as making a home garden (67.8%, 63.7 to 71.6%), growing fruit and vegetables (59.5%, 55.6 to 63.8%), or trying to eat healthier (14.7%, 12.0 to 18.0%). There were no significant associations between food insecurity and intakes of salt, sugar or fruit and vegetables. CONCLUSION: Participants reported high levels of food insecurity, exceeding recommendations for salt and sugar intake and not meeting fruit and vegetable recommendations, and becoming more food insecure due to COVID-19. Most participants reported making home gardens and/or growing fruit and vegetables in response to the pandemic. There is an opportunity for these activities to be fostered in addressing food insecurity in Fiji, with likely relevance to the Pacific region and other Small Island Developing States who face similar food insecurity challenges.

Objective: To determine the contribution of pre-packaged foods to population sodium intake in China, and to propose sodium content targets for food subcategories used for the World Health Organization's (WHO's) global sodium benchmarks. Methods: The impact of four different approaches to reducing the sodium content of pre-packaged foods on population sodium intake was estimated using data from national databases covering the nutrient content and ingredients of 51 803 food products and food consumption by 15 670 Chinese adults. We recategorized food products using a food categorization framework developed for WHO's global sodium benchmarks and adapted for China-specific foods. Findings: Pre-packaged foods, including condiments, contributed 1302.5 mg/day of sodium intake per adult in 2021, accounting for 30.1% of population sodium intake in China. Setting maximum sodium content levels using a 90th-percentile target would reduce sodium intake from pre-packaged foods by 96.2 mg/day, corresponding to a 1.9% reduction in population intake. Using the 75th-percentile, a fixed 20% reduction and WHO benchmark targets would further reduce intake by 262.0 mg/day (5.2% population intake), 302.8 mg/day (6.0% population intake) and 701.2 mg/day per person (13.9% population intake), respectively. Maximum sodium content levels based on revised 20% reduction targets were proposed because they should result in substantial and acceptable reductions in sodium content for most food subcategories: overall sodium intake would decline by 305.0 mg/day per person, and population intake by 6.1%. Conclusion: This study provides the scientific rationale for government policy on setting targets for food sodium content in China. Simultaneous action on discretionary salt use should also be taken.

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.

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.

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.

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.

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.

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.

Excess dietary salt intake is well established as a leading cause of high blood pressure and associated cardiovascular disease, yet current salt intake in India is nearly 11 g per day, more than twice World Health Organization maximum recommended intake of 5 g per day. Although dietary survey data from India indicate that the main sources of dietary salt are salt added during cooking at home, and few salt reduction efforts have focused on interventions at the household level. As a result, there is little evidence of the effectiveness of behavior change programs to reduce salt intake at the household level. The study aims to develop and implement a community based behavioral change intervention to reduce salt intake delivered by front line community-based health volunteers; and evaluate the preliminary effectiveness, acceptability, and feasibility of delivering a salt reduction behavior change program and potential to support future scale-up. The study is a pre-post intervention design, and outcomes will be evaluated from a random sample of 1500 participants from 28 villages in two primary health centers in Siddipet, Telangana. Primary outcome is change in salt-related KAB (knowledge, attitude, and behavior) score, and secondary outcomes will be changes in salt intake measured by 24 h urinary sodium excretion and change in scores using the subscales of the COM-B ("capability", "opportunity", "motivation" and "behavior") tool. Findings will be used to inform future public health policies to support implementation of scalable community-based interventions to reduce salt intake and control hypertension, the leading-cause of death in India.

Blood pressure (BP) rises rapidly at puberty. While this is partly due to normal development, factors like excess adiposity and a high intake of dietary sodium relative to potassium may contribute to a true increase in hypertension risk. This study aimed to assess the relative impact of growth, gonadal hormones, adiposity and the sodium-to-potassium ratio (Na:K) on longitudinal BP measures at puberty. This study analysed data from a three-year longitudinal cohort study of pubertal adolescents. Anthropometry, body composition (bio-electrical impedance), serum testosterone and oestradiol (mass spectrometry) were measured annually. Na:K was measured from three-monthly urine samples. These variables were used to predict annual BP measures using mixed modelling and ordinal regression. Data from 325 adolescents (11.7 ± 1.0 y; 55% male) were analysed, showing typical growth patterns at puberty. Systolic BP increased over time in both sexes (p < 0.01), with boys exhibiting a significantly steeper rise compared to girls. Adiposity variables (BMI z-score, percent body fat, fat mass, waist-to-height ratio) strongly and consistently predicted systolic and diastolic BP in both sexes (all p < 0.05). Systolic BP was also significantly and positively related to height (p < 0.05). No associations with BP were identified in either sex for gonadal hormones or Na:K. Similar results were obtained when BP was classified into hypertension categories. Relative to other developmental and diet-related variables tested, adiposity was found to be the strongest most consistent predictor of BP in pubertal adolescents. Findings highlight the importance of dedicated youth obesity management interventions and policy measures for reducing long-term hypertension and cardiovascular disease risks.Australian New Zealand Clinical Trials Registry ACTRN12617000964314.

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.

BACKGROUND: Public support for evidence-based nutrition interventions can be an important determinant of government willingness to develop and implement such interventions. The aim of this study was to assess support for a broad range of nutrition interventions across seven countries: Australia, Canada, China, India, New Zealand, the United Kingdom, and the United States. Assessed interventions included those relating to food availability, affordability, reformulation, labelling, and promotion. METHODS: Approximately 1000 adults per country (total n = 7559) completed an online survey assessing support for 35 nutrition interventions/policies. ANOVA analyses were used to identify differences between countries on overall levels of support and by intervention category. Multiple regression analyses assessed demographic and diet-related factors associated with higher levels of support across the total sample and by country. RESULTS: Substantial levels of public support were found for the assessed interventions across the seven countries and five intervention categories. The highest levels were found in India (Mean across all interventions of 4.16 (standard deviation (SD) 0.65) on a 5-point scale) and the lowest in the United States (Mean = 3.48, SD = 0.83). Support was strongest for interventions involving food labelling (Mean = 4.20, SD = 0.79) and food reformulation (Mean = 4.17, SD = 0.87), and weakest for fiscal interventions (Mean = 3.52, SD = 1.06). Consumer characteristics associated with stronger support were higher self-rated health, higher educational attainment, female sex, older age, and perceptions of consuming a healthy diet. CONCLUSION: The results indicate substantial support for a large range of nutrition interventions across the assessed countries, and hence governments could potentially be more proactive in developing and implementing such initiatives.

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.
