International audience ; The European Union (EU) approach to assessing exposure to chemical migrants from plastic Food Contact Materials (FCMs) has been to assume an intake of 1 kg of food in contact with a particular material, per 60 kg person per day, which equates to 16.7 g/kg body weight. A food packaging surface area to food mass ratio of 6dm2/1kg is assumed, equivalent to 0.1dm2/kg of body weight. Children may be at increased risk to exposure from migrants as they have higher intakes of food per kg body weight compared with adults. In addition, much of the food marketed for/to children is in small portions and therefore the FCM area to food mass ratio is relatively high. To determine if, and how, the EU model might be modified to ensure specific protection against chemical migration into food marketed for children, data on 4-day food intakes of 297 children aged 0 to 6 years were collected including information on pack size, pack type and FCM area to food mass ratio. The 297 children consumed a total of 1,646 kg of food and drink (including tap water) of which 978 kg (59%) was packaged with 67% of this packaged in plastics. Mean intakes of food packaged in plastic ranged from 27g per kg body weight (for the infants under 1 year) to 51 g per kg body weight (for the 1-4 year olds). This was higher than the 16.7 g/kg body weight derived from the EU convention. The mean area of packaging in contact with the food consumed daily per kg body weight were 0.65 dm2/kg for the infants under one, 0,81 dm2/kg for the 1-4 year olds and 0.66 dm2/kg for the 4-6 year olds. All 297 children had intakes which exceeded 0.1dm2 of packaging per kg of body weight assumption.

Abstract Background The 2008 nutritional standards for primary school lunch in England improved nutritional content. The impact on socio-economic inequalities is unknown. We examine the impact of the nutritional standards on children's nutrient intake at lunchtime and in total diet by level of deprivation. Methods We conducted cross-sectional studies in 12 English primary schools before and after legislation. Dietary intake was recorded for 4-7y olds using a validated, prospective four-day food diary. Socio-economic status was estimated using the Index of Multiple Deprivation; three groups of approximately equal sizes were created. Linear, mixed-effect models explored the effect of year, lunch type (school or home-packed lunch), level of deprivation and the interaction(s) between these factors on children's diets. Results 368 and 624 children participated in 2003–4 and 2008–9 respectively. At lunchtime, between 2003–4 and 2008–9, the increase in non-starch polysaccharide (NSP) intake was larger in the least compared to the most deprived group (difference in mean change 0.8 mg; 95% CI 0.4, 1.3). There were similar differences in mean changes for iron (0.3 mg; 0.2, 0.4) and zinc (0.3 mg; 0.1, 0.5). In total diet, differential effects were observed for NSP, iron and zinc; we found no evidence these changes were associated with lunch type. Lunch type was associated with changes in per cent energy from non-milk-extrinsic sugars (NMES) and vitamin C. Per cent energy from NMES was lower and vitamin C intake higher in school lunches in 2008–9 compared with 2003–4. The corresponding differences in home-packed lunches were not as marked and there were subtle but statistically significant effects of the level of deprivation. Conclusions By 2008–9, NMES at lunchtime and in total diet was lower for children consuming a school lunch; this change was equitable across the deprivation groups. Vitamin C intake increased more for children in the most deprived group, narrowing the socio-economic inequality. A range of significant differential effects of the nutritional standards were observed and important socio-economic inequalities in dietary intake remain. Additional interventions to promote equitable nutrition in children are needed to support legislative measures and maximise their impact.

BACKGROUND: Co-production of research evidence is valued by local government to improve effective decision-making about public services in times of austerity. However, underlying structural issues of power (so-called 'dark shadows of co-production') challenge this ambition with limited evidence on how to embed research use sustainably. In this paper we reflect on mechanisms for increasing co-production in local government. METHODS: This paper presents findings from a Health Foundation funded research project that explored how a culture of evidence use to improve population health could be embedded in UK local government. Five linked work packages were undertaken using mixed methods. In this paper, we report the views of UK local authority staff who participated in four workshops (n = 54), informed by a rapid literature review and an online scoping survey. RESULTS: We identified five themes that facilitate public health evidence use in local government: (1) new governance arrangements to integrate national and local policies, (2) codifying research evidence through local system-wide approaches and (3) ongoing evaluation of programmes, and (4) overcoming political and cultural barriers by increasing absorptive capacity of Local Authorities to embed co-produced knowledge in their cognitive structures. This requires adaptive governance through relationship building between academic researchers and Local Authority staff and shared understanding of fragmented local policy making, which are supported by (5) collective spaces for reflection within local government. CONCLUSIONS: Creating collective spaces for reflection in between government departments allows for iterative, interactive processes of co-production with external partners that support emergence of new governance structures to socially action the co-produced knowledge in context and build capacity for sustained evidence use.

Background:Local government (LG) is ideally placed to influence the determinants of public health (PH) and reduce inequalities, but opportunities are routinely missed.
Aims and objectives:The aim of the Local Authority Champions of Research (LACoR) study was to explore ways to embed a culture of evidence use in LG.
Methods:Five linked work packages were undertaken using mixed methods. In this paper, we report data from semi-structured interviews with UK local authority (LA) staff (n=14).
Findings:Findings show a changing culture of LG: embedded researchers can enhance connectivity and interaction, build linkages, use levers of influence, and learn alongside LG navigators. Understanding the diverse microcultures of evidence use in LG is critical. Research champions can help to navigate the social, financial, political and regulatory context of LG and academia, influencing change dynamically as opportunities emerge.
Discussion:Changing organisational subcultures is ambitious and unpredictable given the complexities of, and variability in, local contexts. Cumulative changes appear possible by recognising existing assets, using relational approaches to respond to LG priorities. In-house capacity remains underestimated and underutilised in efforts to embed evidence use in LG decision making. Co-located embedded researchers can use contextually specific knowledge and relationships to enhance evidence use in LG in collaboration with system navigators.
Conclusions:There is a need for academics to adapt their approach, to take account of the context of LG to achieve meaningful health and social impacts with LG and test the contribution of embedded approaches to wider system change.

Background: Takeaway food has a relatively poor nutritional profile. Providing takeaway outlets with reduced-holed salt shakers is one method thought to reduce salt use in takeaways, but effects have not been formally tested. We aimed to determine if there was a difference in sodium content of standard fish and chip meals served by Fish & Chip Shops that use standard (17 holes) versus reduced-holed (5 holes) salt shakers, taking advantage of natural variations in salt shakers used. Methods: We conducted a cross-sectional study of all Fish & Chip Shops in two local government areas (n = 65), where servers added salt to meals as standard practice, and salt shaker used could be identified (n = 61). Standard fish and chip meals were purchased from each shop by incognito researchers and the purchase price and type of salt shaker used noted. Sodium content of full meals and their component parts (fish, chips, and fish batter) was determined using flame photometry. Differences in absolute and relative sodium content of meals and component parts between shops using reduced-holed versus standard salt-shakers were compared using linear regression before and after adjustment for purchase price and area. Results: Reduced-holed salt shakers were used in 29 of 61 (47.5 %) included shops. There was no difference in absolute sodium content of meals purchased from shops using standard versus reduced-holed shakers (mean = 1147 mg [equivalent to 2.9 g salt]; SD = 424 mg; p > 0.05). Relative sodium content was significantly lower in meals from shops using reduced-holed (mean = 142.5 mg/100 g [equivalent to 0.4 g salt/100 g]; SD = 39.0 mg/100 g) versus standard shakers (mean = 182.0 mg/100 g; [equivalent to 0.5 g salt/100 g]; SD = 68.3 mg/100 g; p = 0.008). This was driven by differences in the sodium content of chips and was extinguished by adjustment for purchase price and area. Price was inversely associated with relative sodium content (p < 0.05). Conclusions: Using reduced-holed salt shakers in Fish & Chip Shops is associated with lower relative sodium content of fish and chip meals. This is driven by differences in sodium content of chips, making our results relevant to the wide range of takeaways serving chips. Shops serving higher priced meals, which may reflect a more affluent customer base, may be more likely to use reduced-holed shakers.

Afterweightloss,mostindividualsregainlostweight.Interventionsto supportthetransitionfromsuccessfullosstoweightlossmaintenance (WLM),regardlessofthemethodofpriorweightloss,areneeded.The aims of this study were to (1) develop a face-to-face behavioural intervention session to support overweight and obese individuals who have recently lost a clinically significant amount of weight in the transition to WLM; (2) to assess the single-session intervention for acceptability and feasibility prior to its use in a larger, 12-month, multi-component trial; and (3) to optimise the intervention session for future use based on participant feedback. Participants with a Body Mass Index of ≥25 kg/m2 prior to a ≥5% weight loss in the previous 12 months were recruited via the local government authority and community-based advertisements. Each attended the one-hour session with a trained facilitator, which focused on setting maintenance-relevant weight, eating, and physical activity goals. Semi-structured interviews were carried out immediately postsession to obtain feedback on the acceptability of this intervention component. Data were used to generate recommendations for changes to the session, which were discussed by the team, and used to optimise the session. Seventeen participants (13 female; median WL=13%) were recruited. All participants evaluated the intervention session positively; 11 participants suggested improvements including reducing information provision in favour ofgreaterfocusonidentifyingandcopingwithbarriers,andtheinclusion of practical examples. The systematic refinement and optimisation process resulted in an acceptable and feasible face-to-face behavioural intervention session (described here), which will be tested as part of a multi-component intervention. We anticipate the session could be used to supplement existing support including online services, and has the potential to benefit people who have lost a clinically significant amount of weight to achieve WLM over the long term.
