RESUMO

BACKGROUND: Supermarket interventions are promising to promote healthier dietary patterns, but not all individuals may be equally susceptible. We explored whether the effectiveness of nudging and pricing strategies on diet quality differs by psychological and grocery shopping characteristics. METHODS: We used data of the 12-month Supreme Nudge parallel cluster-randomised controlled supermarket trial, testing nudging and pricing strategies to promote healthier diets. Participants were Dutch speaking adults aged 30-80 years and regular shoppers of participating supermarkets (n = 12) in socially disadvantaged neighbourhoods. Data on psychological characteristics (food-related behaviours; price sensitivity; food decision styles; social cognitive factors; self-control) and grocery shopping characteristics (time spent in the supermarket; moment of the day; average supermarket visits; shopping at other retailers; supermarket proximity) were self-reported at baseline. These characteristics were tested for their moderating effects of the intervention on diet quality (scored 0-150) in linear mixed models. RESULTS: We included 162 participants from intervention supermarkets and 199 from control supermarkets (73% female, 58 (± 10.8) years old, 42% highly educated). The interventions had no overall effect on diet quality. Only five out of 23 potential moderators were statistically significant. Yet, stratified analyses of these significant moderators showed no significant effects on diet quality for one of the subgroups and statistically non-significant negative effects for the other. Negative effects were suggested for individuals with lower baseline levels of meal planning (ß - 2.6, 95% CI - 5.9; 0.8), healthy shopping convenience (ß - 3.0, 95% CI - 7.2; 1.3), and healthy food attractiveness (ß - 3.5, 95% CI - 8.3; 1.3), and with higher levels of price consciousness (ß - 2.6, 95% CI - 6.2; 1.0) and weekly supermarket visits (ß - 2.4, 95% CI - 6.8; 1.9). CONCLUSIONS: Adults with varying psychological and grocery shopping characteristics largely seem equally (un)susceptible to nudging and pricing strategies. It might be that certain characteristics lead to adverse effects, but this is not plausible, and the observed negative effects were small and statistically non-significant and may be explained by chance findings. Verification of these findings is needed in real-world trials based on larger sample sizes and with the use of more comprehensive interventions.

RESUMO

BACKGROUND: Early initiation of breastfeeding (EIBF) is a starting point that lays the foundation for breastfeeding and bonding between mother and baby. Meanwhile, working mothers are one of the vulnerable groups for the success of exclusive breastfeeding (EBF). The study analyzed the role of EIBF on EBF among Indonesian working mothers. METHODS: The cross-sectional study examined secondary data from the 2021 Indonesian National Nutritional Status Survey. The study analyzed 4,003 respondents. We examined EBF practice as an outcome variable and EIBF as an exposure variable. We included nine control variables (residence, maternal age, marital, education, prenatal classes, wealth, infant age, sex, and birth weight). All variables were assessed by questionnaire. The study employed a binary logistic regression test in the last stage. RESULTS: The result showed that the proportion of EBF among working mothers in Indonesia in 2021 was 51.9%. Based on EIBF, Indonesian working mothers with EIBF were 2.053 times more likely than those without to perform EBF (p < 0.001; AOR 2.053; 95% CI 2.028-2.077). Moreover, the study also found control variables related to EBF in Indonesia: residence, maternal age, marital, education, prenatal classes, wealth, infant age, sex, and birth weight. CONCLUSION: The study concluded that EIBF was related to EBF. Indonesian working mothers with EIBF were two times more likely than those without to perform EBF. The government needs to release policies that strengthen the occurrence of EIBF in working mothers to increase EBF coverage.

RESUMO

BACKGROUND: School canteens are a recommended setting to influence adolescent nutrition due to their scope to improve student food choices. Online lunch ordering systems ("online canteens") are increasingly used and represent attractive infrastructure to implement choice architecture interventions that nudge users toward healthier food choices. A recent cluster randomized controlled trial demonstrated the short-term effectiveness (2-month follow-up) of a choice architecture intervention to increase the healthiness of foods purchased by high school students from online canteens. However, there is little evidence regarding the long-term effectiveness of choice architecture interventions targeting adolescent food purchases, particularly those delivered online. OBJECTIVE: This study aimed to determine the long-term effectiveness of a multi-strategy choice architecture intervention embedded within online canteen infrastructure in high schools at a 15-month follow-up. METHODS: A cluster randomized controlled trial was undertaken with 1331 students (from 9 high schools) in New South Wales, Australia. Schools were randomized to receive the automated choice architecture intervention (including menu labeling, positioning, feedback, and prompting strategies) or the control (standard online ordering). The foods purchased were classified according to the New South Wales Healthy Canteen strategy as either "everyday," "occasional," or "should not be sold." Primary outcomes were the average proportion of "everyday," "occasional," and "should not be sold" items purchased per student. Secondary outcomes were the mean energy, saturated fat, sugar, and sodium content of purchases. Outcomes were assessed using routine data collected by the online canteen. RESULTS: From baseline to 15-month follow-up, on average, students in the intervention group ordered significantly more "everyday" items (+11.5%, 95% CI 7.3% to 15.6%; P<.001), and significantly fewer "occasional" (-5.4%, 95% CI -9.4% to -1.5%; P=.007) and "should not be sold" items (-6%, 95% CI -9.1% to -2.9%; P<.001), relative to controls. There were no between-group differences over time in the mean energy, saturated fat, sugar, or sodium content of lunch orders. CONCLUSIONS: Given their longer-term effectiveness, choice architecture interventions delivered via online canteens may represent a promising option for policy makers to support healthy eating among high school students.

RESUMO

BACKGROUND: Disruptions from the coronavirus disease 2019 (COVID-19) pandemic potentially exacerbated food insecurity among adults and youth. OBJECTIVES: The objective was to examine changes in the prevalence and severity of food insecurity among adults and youth from before (2019) to during (2020) the pandemic in multiple countries. METHODS: Repeated cross-sectional data were collected among adults aged 18-100 y (n = 63,278) in 5 countries in November to December in 2018-2020 and among youth aged 10-17 y (n = 23,107) in 6 countries in November to December in 2019 and 2020. Food insecurity in the past year was captured using the Household Food Security Survey Module and the Child Food Insecurity Experiences Scale. Changes in the prevalence and severity of food insecurity were examined using logistic and generalized logit regression models, respectively. Models included age, gender, racial-ethnic identity, and other sociodemographic characteristics associated with food insecurity to adjust for possible sample differences across waves. Models were weighted to reflect each country's population. RESULTS: Adults [adjusted OR (AOR): 1.15; 95% CI: 1.02, 1.31] and youth (AOR: 1.43; 95% CI: 1.19, 1.71) in Mexico were more likely to live in food-insecure households in 2020 compared to 2019. Adults in Australia (AOR: 0.81; 95% CI: 0.72, 0.92) and Canada (AOR: 0.87; 95% CI: 0.77, 0.99) were less likely to live in food-insecure households in 2020. Trends in severity aligned with changes in prevalence, with some exceptions. Youth in Australia (AOR: 2.24; 95% CI: 1.65, 3.02) and the United States (AOR: 1.39; 95% CI: 1.04, 1.86) were more likely to have many compared with no experiences of food insecurity in 2020 compared to 2019. There was no evidence of change among adults and youth in the remaining countries. CONCLUSIONS: Except for Mexico, few changes in food insecurity among adults and youth were observed from before to during the COVID-19 pandemic. Action is needed to support households at risk of food insecurity.

RESUMO

BACKGROUND: The National Health Service (NHS) website gives guidance for pregnant women in England on foods/drinks to avoid or limit because of microbiological, toxicological or teratogenic hazards. These include, for example, some types of soft cheeses, fish/seafood and meat products. This website and midwives are trusted sources of information for pregnant women, but the ways in which midwives can be supported to provide clear and accurate information are unknown. AIMS: The aims were to: (1) determine midwives' accuracy of recall of information and confidence in delivering the guidance to women; (2) identify barriers to provision; (3) identify the ways in which midwives provide this information to women. METHODS: Registered Midwives practicing in England completed an online questionnaire. Questions included those on what information they provided and their confidence in delivering it, the ways they provided information on foods to avoid/limit, their recall of some of the guidance, and what resources they used. Ethics approval was given by the University of Bristol. RESULTS: More than 10% of midwives (n = 122) were 'Not at all confident/Don't know' in providing advice about ten items, including game meat/gamebirds (42% and 43%, respectively), herbal teas (14%) and cured meats (12%). Only 32% correctly recalled overall advice on eating fish, and only 38% the advice on tinned tuna. The main barriers to provision were lack of time in appointments and lack of training. The most usual methods of disseminating information were verbal (79%) and signposting to websites (55%). CONCLUSION: Midwives were often unconfident about their ability to provide accurate guidance, and recall on items tested was frequently mistaken. Delivery of guidance by midwives on foods to avoid or limit needs to be supported by appropriate training and access to resources, and sufficient time in appointments. Further research on barriers to the delivery and implementation of the NHS guidance is needed.

RESUMO

BACKGROUND: Fiber, potassium and calcium are nutrients of public health concern and their intakes in the United States are alarmingly low. The usage of nutrition facts labels has been reported to increase the odds for dietary reference intake of fiber in some studies. The overall evidence, however, is mixed, as some studies suggested that nutrition facts panels have little to no effect on average measures of diet quality. Here, we investigated whether the usage of nutrition facts labels was associated with meeting U.S. intake recommendations for three nutrients of public health concern: fiber, potassium and calcium. METHODS: We used cross-sectional multistage, stratified, clustered and probability sampling design data from the U.S. National Health and Nutrition Examination Surveys 2017-2020 cycle. The sample included 5,416 individuals aged 20 years or older, which may be extrapolated to represent 146,841,866 US Americans. Nutrient intakes were compared among individuals reading nutrition facts panels "frequently", "sometimes" or "rarely" using applied survey data analyses techniques (including multivariate logistic regression and marginsplots). RESULTS: We observed substantial sociodemographic differences between the three groups. Frequent readers were significantly more likely to be female and had higher educational levels. On average, they were also significantly older as compared to rare readers. Fiber intake in g/d was highest in frequent readers (17.09) and lowest in rare readers (14.64). The proportion of participants that met dietary fiber intake recommendations was almost four times higher in the frequent readers group (12.69%) as compared to the rare readers group (3.69%). In a bivariate logistic regression model, frequent label reading significantly increased the odds for meeting the fiber recommendations in Dietary Guidelines for Americans (OR: 2.15, p < 0.001). Rarely reading labels decreased the odds (OR: 0.57, p = 0.003). These odds remained essentially unchanged after adjusting for sociodemographic covariates, diabetes status and body mass index (OR: 1.84, p = 0.004; and OR: 0.62, p = 0.022). CONCLUSIONS: Nutrition facts panel reading associates with fiber intake. Our findings have potential implications for public health nutrition strategies that may center around educational work.

RESUMO

BACKGROUND: School is an important setting for creating healthy and sustainable food environments. Using participatory methods, this pilot study examined food and packaging waste and nutrition quality within the school food system. METHODS: One secondary school in Ireland participated in a waste audit. Eleven male students (15-17 years) participated as citizen scientists. Students collected waste over 1 day and documented data on waste categories. Nutrition labels were photographed for analysis. Students created a video and participated in a focus group. Quantitative data were summarised using descriptive frequencies. A Nutrient Profile Model was applied to summarise nutrition quality. The focus group discussion was analysed using content analysis. RESULTS: Highest weights of waste were organic waste (14.2 kg), paper and cardboard (5.0 kg), and hard plastics (4.1 kg). Materials banned by the European Union Single Use Plastics Directive were found. Recycling bins were contaminated with food waste. Nutrition labels from 132 food packages were analysed, of which 115 items (87%) were low-nutrient, energy dense foods. Confectionary, energy bars and desserts and savoury snacks were the most common packaged food groups. Students were not surprised by the unhealthy food choices; however, they were shocked and saddened at the waste practices. Their proposed solutions mapped across individual, community and organisational levels. CONCLUSIONS: The methodologies allowed successful engagement with students on this topic. The use of unnecessary plastics to serve food, poor waste separation practices, and the production of avoidable waste from low-nutrient, energy-dense products were key issues identified. Students proposed solutions that are achievable in the short-term.

RESUMO

Upon moving to a new country and new food environment, 2 important public health issues may be experienced by immigrants as they adapt to their new country of residence, namely a higher prevalence of food insecurity and/or a decline in overall health over time postimmigration. Therefore, improving the food environment experienced by new migrants may be an effective strategy to reduce long-term health complications and improve well-being postimmigration. The aim of this paper is to discuss the potential barriers experienced by new immigrants in the access, availability, and utilization of familiar culturally appropriate foods and the subsequent impact on their food security status. Culturally appropriate foods are foods commonly consumed as part of cultural food traditions and are often staples within the diet; however, limited availability of and/or access to these foods can reduce food security. By understanding the barriers to food security and challenges that may be faced by immigrants and refugees, dietitians will be better equipped to assist these individuals in accessing culturally familiar foods and improve quality of life. In this capacity, dietitians can play a critical public health nutrition role by serving as a conduit for new immigrants to access community resources and navigate a new food environment.

RESUMO

PURPOSE: There is conflicting advice about the inclusion of dairy foods in a lower greenhouse gas (GHG) emission dietary pattern. Our purpose was to assess the prevalence of dairy food intake among higher diet quality and lower GHG emission diets in Australia and within these diets assess the association between level of dairy food intake and adequate intake of a broad range of nutrients. METHODS: Dietary intake data collected using a 24-h recall process were sourced from the most recent Australian Health Survey. Diet quality was assessed by level of compliance with the food group-based Australian Dietary Guidelines. A subgroup of 1732 adult (19 years and above) daily diets was identified having higher diet quality score and lower GHG emissions (HQLE). Intake of core dairy foods (milk, cheese, yoghurt) was assessed and nutrient profiling was undertaken for 42 macro- and micronutrients. RESULTS: The HQLE subgroup had 37% higher diet quality score and 43% lower GHG emissions than the average Australian adult diet (P < 0.05). Intake of dairy foods was very common (90% of HQLE diets) and greatly exceeded the intake of non-dairy alternatives (1.53 serves compared to 0.04 serves). HQLE daily diets in the highest tertile of dairy food intake were more likely to achieve the recommended intake of a wide range of nutrients, including calcium, protein, riboflavin, vitamin B12, folate, phosphorous, magnesium, iodine and potassium compared to other HQLE daily diets. CONCLUSION: Core dairy foods have an important role for achieving adequate nutrient intakes in a healthy and lower GHG emission dietary pattern in Australia.

RESUMO

OBJECTIVE: A core function of the public health nutrition workforce is advocacy. Little is known of the nutritionists' role in policymaking from a policy process theory perspective. The current study analyses the nutritionists' role in advocating for a six-year governmental plan on obesity prevention in Quebec, Canada. DESIGN: We conducted qualitative research using Quebec's obesity policy as a case study to understand the role of nutritionists in advocating for obesity prevention policies. A conceptual framework combining the Advocacy Coalition Framework with a political analysis model based on the Theory of the Strategic Actor was developed to analyse the beliefs, interests and strategies of policy actors including nutritionists. Data sources comprised semi-structured open-ended interviews with key policy actors (n 25), including eight nutritionists (32 %) and policy-related documents (n 267). Data analysis involved thematic coding and analysis using NVivo 11 Pro. SETTING: Quebec, Canada. PARTICIPANTS: Key policy actors including nutritionists. RESULTS: Nutritionists formed the core of the dominant public health coalition. They advocated for an inter-sectoral governmental plan to prevent obesity through enabling environments. Their advocacy, developed through an iterative process, comprised creating a think tank and reinforcing partnerships with key policy actors, conducting research and developing evidence, communicating policy positions and advocacy materials, participating in deliberative forums and negotiating an agreement with other coalitions in the policy subsystem. CONCLUSIONS: Nutritionists' advocacy influenced agenda setting and policy formulation. This research may contribute to empowering the public health nutrition workforce and strengthening its advocacy practices. It informs practitioners and researchers concerned with obesity policy and workforce development.

RESUMO

BACKGROUND: Healthy Start is a food assistance programme in the United Kingdom (UK) which aims to provide a nutritional safety-net and enable low-income families on welfare benefits to access a healthier diet through the provision of food vouchers. Healthy Start was launched in 2006 but remains under-evaluated. This study aims to determine whether participation in the Healthy Start scheme is associated with differences in food expenditure in a nationally representative sample of households in the UK. METHODS: Cross-sectional analyses of the Living Costs and Food Survey dataset (2010-2017). All households with a child (0-3 years) or pregnant woman were included in the analysis (n = 4869). Multivariable quantile regression compared the expenditure and quantity of fruit and vegetables (FV), infant formula and total food purchases. Four exposure groups were defined based on eligibility, participation and income (Healthy Start Participating, Eligible Non-participating, Nearly Eligible low-income and Ineligible high-income households). RESULTS: Of 876 eligible households, 54% participated in Healthy Start. No statistically significant differences were found in FV or total food purchases between participating and eligible non-participating households, but infant formula purchases were lower in Healthy Start participating households. Ineligible higher-income households had higher purchases of FV. CONCLUSION: This study did not find evidence of an association between Healthy Start participation and FV expenditure. Moreover, inequalities in FV purchasing persist in the UK. Higher participation and increased voucher value may help to improve programme performance and counteract the harmful effects of poverty on diet.

RESUMO

BACKGROUND: In 2019, Canada's Food Guide underwent its first transformation in over a decade. The change received considerable attention given the increased focus on plant-based proteins and the decision to eliminate the milk and alternatives food group. Yet little is known about health professionals' views of these updates. In response, the present study examined Canadian dietitians' attitudes and behaviours towards the guide's expanded plant-based recommendations. METHODS: A pan-Canadian cross-sectional online survey was administered from January to March 2020 to currently practicing registered dietitians. The study was pre-registered, piloted and received ethical approval. Descriptive and inferential statistics were performed and open-text responses underwent thematic analysis. RESULTS: In total, 411 dietitians from 10 provinces and various work settings participated. Most dietitians (82.8%) consider the food guide's recommendation to choose protein foods that come from plants more often is evidence-based. Compared to its predecessor, dietitians encourage their patients/clients to choose protein foods that come from plants (p < 0.001) and non-dairy sources of calcium (p < 0.001) significantly more frequently under the new guide. A slight majority of dietitians (57.7%) agree with the decision to omit the standalone milk and alternatives group in favour of bringing dairy into the protein category. CONCLUSIONS: Canadian dietitians generally look favourably upon the new plant-based recommendations and have adjusted their nutrition counselling in response. The findings are considered to be the first to characterise how dietitians view changes to the plant-based content of one of the most recognisable diet-related educational tools in Canada.

RESUMO

BACKGROUND: School food services, including cafeterias and canteens, are an ideal setting in which to improve child nutrition. Online canteen ordering systems are increasingly common and provide unique opportunities to deliver choice architecture strategies to nudge users to select healthier items. Despite evidence of short-term effectiveness, there is little evidence regarding the long-term effectiveness of choice architecture interventions, particularly those delivered online. OBJECTIVE: This study determined the long-term effectiveness of a multistrategy behavioral intervention (Click & Crunch) embedded within an existing online school lunch-ordering system on the energy, saturated fat, sugar, and sodium content of primary school students' lunch orders 18 months after baseline. METHODS: This cluster randomized controlled trial (RCT) involved a cohort of 2207 students (aged 5-12 years) from 17 schools in New South Wales, Australia. Schools were randomized to receive either a multistrategy behavioral intervention or the control (usual online ordering only). The intervention strategies ran continuously for 14-16.5 months until the end of follow-up data collection. Trial primary outcomes (ie, mean total energy, saturated fat, sugar and sodium content of student online lunch orders) and secondary outcomes (ie, the proportion of online lunch order items that were categorized as everyday, occasional, and caution) were assessed over an 8-week period at baseline and 18-month follow-up. RESULTS: In all, 16 schools (94%) participated in the 18-month follow-up. Over time, from baseline to follow-up, relative to control orders, intervention orders had significantly lower energy (-74.1 kJ; 95% CI [-124.7, -23.4]; P=.006) and saturated fat (-0.4 g; 95% CI [-0.7, -0.1]; P=.003) but no significant differences in sugar or sodium content. Relative to control schools, the odds of purchasing everyday items increased significantly (odds ratio [OR] 1.2; 95% CI [1.1, 1.4]; P=.009, corresponding to a +3.8% change) and the odds of purchasing caution items significantly decreased among intervention schools (OR 0.7, 95% CI [0.6, 0.9]; P=.002, corresponding to a -2.6% change). There was no between-group difference over time in canteen revenue. CONCLUSIONS: This is the first study to investigate the sustained effect of a choice architecture intervention delivered via an online canteen ordering systems in schools. The findings suggest that there are intervention effects up to 18-months postbaseline in terms of decreased energy and saturated fat content and changes in the relative proportions of healthy and unhealthy food purchased for student lunches. As such, this intervention approach may hold promise as a population health behavior change strategy within schools and may have implications for the use of online food-ordering systems more generally; however, more research is required.

RESUMO

OBJECTIVE: To assess public health nutrition practice within the public health system in Ontario, Canada to identify provincial-wide needs for scientific and technical support. DESIGN: A qualitative descriptive study was conducted to identify activities, strengths, challenges and opportunities in public health nutrition practice using semi-structured key informant interviews (n 21) and focus groups (n 10). Recorded notes were analysed concurrently with data generation using content analysis. System needs were prioritised through a survey. SETTING: Public health units. PARTICIPANTS: Eighty-nine practitioners, managers, directors, medical officers of health, researchers and other stakeholders were purposively recruited through snowball and extreme case sampling. RESULTS: Five themes were generated: (i) current public health nutrition practice was broad, complex, in transition and collaborative; (ii) data/evidence/research relevant to public health needs were insufficiently available and accessible; (iii) the amount and specificity of guidance/leadership was perceived to be mismatched with strong evidence that diet is a risk factor for poor health; (iv) resources/capacity were varied but insufficient and (v) understanding of nutrition expertise in public health among colleagues, leadership and other organisations can be improved. Top ranked needs were increased understanding, visibility and prioritisation of healthy eating and food environments; improved access to data and evidence; improved collaboration and coordination; and increased alignment of activities and goals. CONCLUSIONS: Collective capacity in the public health nutrition can be improved through strategic system-wide capacity-building interventions. Research is needed to explore how improvements in data, evidence and local contexts can bridge research and practice to effectively and efficiently improve population diets and health.

RESUMO

OBJECTIVE: To explore parents' responses to sponsorship of children's sport by unhealthy food brands and two alternative pro-health sponsorship options. DESIGN: Between-subjects online experiment with four sponsorship conditions: (i) non-food branding (control); (ii) unhealthy food branding; (iii) healthier food branding; (iv) public health nutrition campaign branding. Participants were shown a short video and a promotional flyer for a fictional junior sports programme, with sponsor content representing their assigned brand. Afterwards, participants were asked a series of questions assessing their brand awareness, brand attitudes and preference for food sponsor branded products. SETTING: Australia. PARTICIPANTS: Australian parents (n 1331) of children aged 6-9 years. RESULTS: Compared with the control condition, unhealthy food sponsorship promoted increased awareness, branded product preferences and favourable attitudes towards unhealthy food sponsor brands. Healthier food sponsorship promoted similar effects for healthier food sponsor brands, except there was no significant increase in positive attitudes towards these brands. Sponsorship by public health nutrition campaigns promoted more negative attitudes towards unhealthy food sponsor brands and increased preference for healthier food sponsor branded products. Overall, healthier food sponsors and public health campaign sponsors were perceived to have better programme-sponsor fit and to be more appropriate sponsors of children's sport than unhealthy food sponsors. CONCLUSIONS: Restrictions on unhealthy food sponsorship of children's sport are needed to prevent unhealthy food brands from exploiting junior sport sponsorship to enhance their appeal. Sponsorship of children's sport by healthier food brands or public health nutrition campaigns could help promote healthier food choices among parents.

RESUMO

Non-communicable diseases (NCD) related to inadequate nutrition are prevalent in economically transitioning countries such as the Arab region. The westernized diet is recognized as a leading trend and the UN General Assembly is focused on the prevention and control of NCD. Due to the rapid transitions in diet and physical inactivity occurring in the Arab region, revising public health dietary strategies, guidelines, and policies to reduce the burden of NCD is needed. This article presents existing literature on food label use in the Arab region as a response to the problem. The primary objective was to locate, review, and summarize peer-reviewed studies on how and why consumers use food labels in Arab countries. An integrative review of the related literature was conducted with no delimiting time frames. The authors applied search strategies to eight academic databases which produced 32 peer-reviewed articles. Seventeen were removed due to inconsistent scope and focus. Awareness of and nutrition knowledge about food labeling emerged as a primary theme. Education, household income, and age were secondary themes and predictor variables. Nutrition food labels as a population-based strategy can influence individual behavior change and potentially improve population health. These outcomes depend on the consumer's ability to understand nutrition labels and properly apply information. Themed recommendations included standardization of food labeling policies, consumer education on food labeling, and public health efforts to develop a detailed understanding of regional populations prior to health promotion strategy development. Enabling informed food selection and reinforcing healthy dietary intake can help prevent NCD and support individual and population health.

RESUMO

OBJECTIVES: The objectives of the study were to investigate access to free school meals (FSMs) among eligible children, to describe factors associated with uptake and to investigate whether receiving FSMs was associated with measures of food insecurity in the UK using the Coronavirus (COVID-19) wave of the UK Household Longitudinal Study. STUDY DESIGN: The study design was cross-sectional analyses of questionnaire data collected in April 2020. METHODS: Six hundred and thirty-five children who were FSM eligible with complete data were included in the analytic sample. Accessing a FSM was defined as receiving a FSM voucher or a cooked meal at school. Multivariable logistic regression was used to investigate (i) associations between characteristics and access to FSMs and (ii) associations between access to FSMs and household food insecurity measures. All analyses accounted for survey design and sample weights to ensure representativeness. RESULTS: Fifty-one percent of eligible children accessed a FSM. Children in junior schools or above (aged 8+ years) (adjusted odds ratio [AOR]: 11.81; 95% confidence interval [CI]: 5.54, 25.19), who belonged to low-income families (AOR: 4.81; 95% CI: 2.10, 11.03) or still attending schools (AOR: 5.87; 95% CI: 1.70, 20.25) were more likely to receive FSMs. Children in Wales were less likely to access FSMs than those in England (AOR: 0.11; 95% CI: 0.03, 0.43). Receiving a FSM was associated with increased odds of recently using a food bank but not reporting feeling hungry. CONCLUSIONS: In the month after the COVID-19 lockdown, 49% of eligible children did not receive any form of FSMs. The present analyses highlight that the voucher scheme did not adequately serve children who could not attend school during the lockdown. Moreover, more needs to be done to support families relying on income-related benefits, who still report needing to access a food bank. As the scheme may be continued in summer or in a potential second wave, large improvements will be needed to improve its reach.

RESUMO

Objectives Food marketing to children is pervasive and linked to increased preference and intake of unhealthy foods. The World Health Organization (WHO) developed the only multi-country nutrient criteria, and Chile recently released the world's most comprehensive regulation to identify foods that should not be marketed to children. Our objective was to examine the proportion of US packaged food and beverage products eligible for marketing to children under the WHO Europe Nutrient Profile Model (NPM) and the 2019 Chilean regulation. Methods Data for this study are from Label Insight's 2017 Open Access branded food database. Each product was assigned to one of 13 food categories, and nutritional content compared to both the NPM and Chilean criteria. The proportion of US products meeting criteria for marketing to children using both schemes was examined overall and by category. Agreement between the two criteria was examined using Cohen's Kappa. Results Of 17,740 US products, 21% were eligible to be marketed to children using the WHO criteria and 26% using the Chilean criteria. 'Egg and egg products' and 'Seafood' had the highest proportion of products eligible for marketing to children under both schemes. 'Confectionery' and 'Snack foods' had the lowest proportion eligible. Conclusions for practice The WHO NPM and Chilean criteria both restrict less healthy items from being marketed to children. Regulatory agencies in the US developing policies should consider the implementation of nutrient criteria to restrict the marketing of less healthy foods and beverages to children and adolescents.

RESUMO

The National Institute of Nutrition (NIN) has reached a remarkable milestone of completing 100 years of exemplary service to the nation. The long journey that started in a humble one-room laboratory at Coonoor (now in Tamil Nadu) in 1918 to a colossus of the nutrition research in the country today is dotted with several interesting vignettes. The NIN has always been at the forefront of need-based, pragmatic research. Its large-scale community-based interventions have been of great practical value in the nation's fight against malnutrition. The evolution of nutrition as a modern science almost coincides with the growth of the Institute. Being the oldest in the fraternity of institutes under the Indian Council of Medical Research (ICMR), the NIN has grown from strength to strength due to the sheer relevance of its contributions in furthering nutrition science and promoting public health in the country. This article provides a historical overview of the evolution and contributions of ICMR-NIN in the areas of nutrition, food safety, public health and policy.

RESUMO

Iodine deficiency disorders (IDDs) constitute a significant public health problem globally. In India, the entire population is prone to IDDs due to deficiency of iodine in the soil of the sub-continent and thus both animal and plant source food grown on the iodine-deficient soil. IDDs encompass the spectrum of disability and disease and include goitre, cretinism, hypothyroidism, abortion, stillbirth, brain damage, learning disabilities, mental retardation, psychomotor defects, hearing and speech impairment. Iodine deficiency is known to be the single largest cause of preventable brain damage. IDDs with their causal association with brain development, cognition, and learning disabilities impair the human resource development and progress of the country. The children born in iodine-deficient regions on an average have 13.5 intelligence quotient (IQ) points lesser than children born in iodine-sufficient regions. IDD control programme in India is a public health success story, with 92 per cent of the population consuming iodized salt. The partnership between government agencies, academic institutions, salt industry, development agencies and civil society has been key to achieve this success story. The sustainable elimination of iodine deficiency in India is within reach, what is required is accelerated and coordinated effort by all key stakeholder at national and State level.
