Drop the Salt! Assessing the impact of a public health advocacy strategy on Australian government policy on salt

Health in Spanish older people: Dietary habits, lifestyles and related socioeconomic factors

Objective

To measure diet quality in the population aged over 65 years in Spain and its autonomous communities and to identify sociodemographic, health and lifestyle factors related to diet quality based on 2017 Spanish National Health Survey.

Methods

To estimate diet quality, we used the Healthy Eating Index for Spanish Population (IASE). A multiple linear regression analysis (regression coefficients and 95 % CIs) was used to determine the relationship between socio-demographic, health and lifestyle factors and IASE. This index was our dependent variable and as independent variables: sex, chronic diseases, age, level of education, engagement in physical activity, marital status and Body Mass Index.

Results

A total of 6325 participants were included in the sample. The diet quality rating in Spain revealed that 0.46 % of our population had an unhealthy diet, 87 % needed to make changes, and 12.3 % were following a healthy diet. Being female (Regression coefficient = 1.6, 95 % CI = 1.14;-1.97), being physically active several times a month (Regression coefficient = 1.6, 95 % CI =0.63-2.48) and several times a week (Regression coefficient = 2.2, 95 % CI =1.36-3.10), having chronic disease (Regression coefficients =0.7, 95 % CI =0.08-1.29), being overweight (Regression coefficient = 0.5, 95 % CI =0.06-0.95) and being aged between 70 and 74 (Regression coefficient = 0.5, 95 % CI =0.01-1.07) and 75-79 (Regression coefficient = 0.9, 95 % CI =0.33-1.50) were associated with higher IASE scores.

Conclusion and implications

These results help to identify risk groups or situations and to design health prevention programs.

A narrative review of regulatory governance factors that shape food and nutrition policies

Food composition, marketing restrictions, nutrition labeling, and taxation policies are recommended for preventing diet-related noncommunicable diseases. In view of the increasing but variable adoption of food policies globally, this narrative review examines the actors, regulatory frameworks, and institutional contexts that shape the development, design, and implementation of these policies. We found a diverse range of actors using various strategies, including advocacy, framing, and evidence generation to influence policy agendas. We identified diverse regulatory designs used in the formulation and implementation of the policies: command and control state regulation for taxes and menu labels, quasi-regulation for sodium reformulation, and co-regulation and industry self-regulation for food marketing policies. Quasi-regulation and industry self-regulation are critiqued for their voluntary nature, lack of independence from the industry, and absence of (or poor) monitoring and enforcement systems. The policy instrument design and implementation best practices highlighted in this review include clear policy goals and rigorous standards that are adequately monitored and enforced. Future research should examine how these combinations of regulatory governance factors influence policy outcomes.

Sources of dietary sodium and implications for a statewide salt reduction initiative in Victoria, Australia

In Victoria, Australia, a statewide salt reduction partnership was launched in 2015. The aim was to measure Na intake, food sources of Na (level of processing, purchase origin) and discretionary salt use in a cross-section of Victorian adults prior to a salt reduction initiative. In 2016/2017, participants completed a 24-h urine collection (n 338) and a subsample completed a 24-h dietary recall (n 142). Participants were aged 41·2 (sd 13·9) years, and 56 % were females. Mean 24-h urinary excretion was 138 (95 % CI 127, 149) mmol/d for Na. Salt equivalent was 8·1 (95 % CI 7·4, 8·7) g/d, equating to about 8·9 (95 % CI 8·1, 9·6) g/d after 10 % adjustment for non-urinary losses. Mean 24-h intake estimated by diet recall was 118 (95 % CI 103, 133) mmol/d for Na (salt 6·9 (95 % CI 6·0, 7·8 g/d)). Leading dietary sources of Na were cereal-based mixed dishes (12 %), English muffins, flat/savoury/sweet breads (9 %), regular breads/rolls (9 %), gravies and savoury sauces (7 %) and processed meats (7 %). Over one-third (38 %) of Na consumed was derived from discretionary foods. Half of all Na consumed came from ultra-processed foods. Dietary Na derived from foods was obtained from retail stores (51 %), restaurants and fast-food/takeaway outlets (28 %) and fresh food markets (9 %). One-third (32 %) of participants reported adding salt at the table and 61 % added salt whilst cooking. This study revealed that salt intake was above recommended levels with diverse sources of intake. Results from this study suggest a multi-faceted salt reduction strategy focusing on the retail sector, and food reformulation would most likely benefit Victorians and has been used to inform the ongoing statewide salt reduction initiative.

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

The Victorian Salt Reduction Partnership (VicSalt Partnership) was launched in 2015, bringing together health and research organisations to develop an action plan for salt reduction interventions at a state level. A comprehensive evaluation was designed to assess the impact of the resulting four-year intervention strategy. As part of the process evaluation, semi-structured interviews were undertaken with stakeholders in March⁻May 2017, to understand perceived barriers and enablers to effective strategy implementation. Data were coded in relation to the key topic areas of the interviews with an inductive method used to analyse themes within topics. Seventeen stakeholders were contacted, 14 completed an interview; five from state government or statutory agencies, four from non-government funded organisations, four from research organisations and one from the food industry. Twelve were members of the VicSalt Partnership and two were informal collaborators. Most stakeholders viewed the VicSalt Partnership as a positive example of working collaboratively, and said this was essential for raising awareness of the importance of salt reduction with consumers, the food industry, and the government. Challenges relating to engaging the food industry and federal government through a state-led initiative were identified. New approaches to overcome this, such as forming clear "asks" to government and committing industry to "pledges" on reformulation were suggested. Stakeholder interviews and qualitative analysis have provided a range of important insights into barriers and enablers, many of which have already been used to strengthen intervention implementation. The evaluation of the VicSalt Partnership is ongoing and the program is expected to provide a wealth of lessons for state-led interventions to reduce salt intake in Australia and globally.

Salt reduction in Australia: from advocacy to action

BACKGROUND

As part of its endorsement of the World Health Organization's Global Action Plan to prevent non-communicable diseases, the Federal Government of Australia has committed to a 30% reduction in average population salt intake by 2025. Currently, mean daily salt intake levels are 8-9 g, varying by sex, region and population group. A number of salt reduction initiatives have been established over the last decade, but key elements for a co-ordinated population-level strategy are still missing. The objective of this review is to provide a comprehensive overview of existing population-level salt reduction activities in Australia and identify opportunities for further action.

METHODS

A review of the published literature and stakeholder activities was undertaken to identify and document current activities. The activities were then assessed against a pre-defined framework for salt reduction strategies.

RESULTS

A range of initiatives were identified from the review. The Australian Division of World Action on Salt and Health (AWASH) was established in 2005 and in 2007 launched its Drop the Salt! Campaign. This united non-governmental organisations (NGOs), health and medical and food industry organisations in a co-ordinated advocacy effort to encourage government to develop a national strategy to reduce salt. Subsequently, in 2010 the Federal Government launched its Food and Health Dialogue (FHD) with a remit to improve the health of the food supply in Australia through voluntary partnerships with food industry, government and non-government public health organisations. The focus of the FHD to date has been on voluntary reformulation of foods, primarily through salt reduction targets. More recently, in December 2014, the government's Health Star Rating system was launched. This front of pack labelling scheme uses stars to highlight the nutritional profile of packaged foods. Both government initiatives have clear targets or criteria for industry to meet, however, both are voluntary and the extent of industry uptake is not yet clear. There is also no parallel public awareness campaign to try and influence consumer behaviour relating to salt and no agreed mechanism for monitoring national changes in salt intake. The Victorian Health Promotion Foundation (VicHealth) has recently instigated a State-level partnership to advance action and will launch its strategy in 2015.

CONCLUSIONS

In conclusion, salt reduction activities are currently being implemented through a variety of different programs but additional efforts and more robust national monitoring mechanisms are required to ensure that Australia is on track to achieve the proposed 30% reduction in salt intake within the next decade.

Sodium content and labelling of processed and ultra-processed food products marketed in Brazil

OBJECTIVE

To analyse the Na content and labelling of processed and ultra-processed food products marketed in Brazil.

DESIGN

Cross-sectional study.

SETTING

A large supermarket in Florianopolis, southern Brazil.

SUBJECTS

Ingredient lists and Na information on nutrition labels of all processed and ultra-processed pre-prepared meals and prepared ingredients, used in lunch or dinner, available for sale in the supermarket.

RESULTS

The study analysed 1416 products, distributed into seven groups and forty-one subgroups. Five products did not have Na information. Most products (58.8 %; 95 % CI 55.4, 62.2 %) had high Na content (>600 mg/100 g). In 78.0 % of the subgroups, variation in Na content was at least twofold between similar products with high and low Na levels, reaching 634-fold difference in the 'garnishes and others' subgroup. More than half of the products (52.0 %; 95 % CI 48.2, 55.6 %) had at least one Na-containing food additive. There was no relationship between the appearance of salt on the ingredients list (first to third position on the list) and a product's Na content (high, medium or low; P=0.08).

CONCLUSIONS

Most food products had high Na content, with great variation between similar products, which presents new evidence for reformulation opportunities. There were inconsistencies in Na labelling, such as lack of nutritional information and incomplete ingredient descriptions. The position of salt on the ingredients list did not facilitate the identification of high-Na foods. We therefore recommend a reduction in Na in these products and a review of Brazilian legislation.
