Understanding trends in grain consumption is essential to tackle the low consumption of healthful grain foods. This study aimed to evaluate trends and determinants of grain foods meeting the ≤10:1 carbohydrate:fibre ratio (≤10:1 ratio) in Brazil and to estimate this intake for the next years.
Design:
Three editions of the cross-sectional, population-based study Health Survey of São Paulo (2003, 2008 and 2015).
Setting:
Urban area of São Paulo, Brazil.
Participants:
The sample included 5801 participants aged 12 years or more.
Results:
A growing trend in the intake of these foods (0·9 percentage of energy (%E) in 2003 to 1·5 %E in 2015) was observed. Also, the proportion of the population consuming at least one grain food meeting the ≤10:1 ratio increased from 8·7 % in 2003 to 15·8 % in 2015, and 20·3 % of the population would be consuming some kind of healthful grain food by 2030. Sociodemographic factors associated with the consumption of grain foods meeting the ≤10:1 ratio changed according to study edition, but overall, older individuals (+79 %), females (+28 %), those with higher education (+138 %) and higher family income (+135 %) were more likely to consume grain foods meeting the ratio, whereas participants who self-reported black, brown or indigenous ethnicity were less likely to consume these foods (–30 %).
Conclusions:
There was a growing trend to consume grain foods meeting the ≤10:1 ratio from 2003 to 2015, but this consumption continues to be far from recommended levels. Intersectoral changes are urgently needed in order to increase the intake of healthful grain foods.
To investigate to what extent promotions in Dutch supermarket sales flyers contribute to a healthy diet and whether there are differences between supermarket types.
Design:
A cross-sectional study investigating promotions on foods and beverages (n 7825) in supermarket sales flyers from thirteen Dutch supermarket chains (8-week period), including ten traditional, two discount and one organic supermarket chain(s). Promoted products were categorised by food group (e.g. bread), contribution to a healthy diet (yes/no), degree of processing (e.g. ultra-processed), promotion type (temporary reduction in price, volume-based promotions or advertised only) and percentage discount of price promotions. Differences between supermarket chains in the degree of healthiness and processing of products and the types of price promotions were investigated.
Results:
In total, 70·7 % of all promoted products in supermarket sales flyers did not contribute to a healthy diet and 56·6 % was ultra-processed. The average discount on less healthy products (28·7 %) was similar to that of healthy products (28·9 %). Less healthy products were more frequently promoted via volume-based promotions than healthy products (37·6 % v. 25·4 %, P < 0·001). Discount supermarket chains promoted less healthy (80·3 %) and ultra-processed (65·1 %) products more often than traditional supermarket chains (69·6 % and 56·6 %, respectively).
Conclusions:
The majority of promoted products via supermarket sales flyers do not contribute to a healthy diet. As promotions are an important determinant of food purchasing decisions, supermarkets do not support healthy choices. Future studies should identify barriers that withhold supermarket chains from promoting more healthy foods in supermarket sales flyers.
The food retail environment is an important determinant of food access and the ability to achieve a healthy diet. However, immigrant communities may procure their food in different ways than the mainstream population owing to preferences for specific cultural products or limited English language proficiency. The objective of this analysis was to describe the grocery shopping patterns and behaviours of one of the largest immigrant groups in New York City, Chinese Americans – a group experiencing high poverty and cardio-metabolic disparities.
Design:
Cross-sectional survey data.
Setting:
Community-based sample.
Participants:
Self-identified Chinese Americans in the New York metropolitan area (n 239).
Results:
Three shopping patterns were identified: type 1: shopped weekly at an ethnic grocery store – and nowhere else; type 2: shopped weekly at a non-ethnic grocery store, with occasional shopping at an ethnic store and type 3: did not perform weekly shopping. Type 1 v. type 2 shoppers tended to have lower education levels (37·5 v. 78·0 % with college degree); to be on public insurance (57·6 v. 22·8 %); speak English less well (18·4 v. 41·4 %); be food insecure (47·2 v. 24·2 %; P < 0·01 for all) and to travel nearly two miles further to shop at their primary grocery store (β = −1·55; 95 % CI −2·81, −0·30).
Discussion:
There are distinct grocery shopping patterns amongst urban-dwelling Chinese Americans corresponding to demographic and sociocultural factors that may help inform health interventions in this understudied group. Similar patterns may exist among other immigrant groups, lending preliminary support for an alternative conceptualisation of how immigrant communities interact with the food retail environment.
The current study aimed to understand how moderate and severe food-insecure people living with HIV (PLHIV) in the Dominican Republic perceive a healthy diet and explore facilitators and barriers to engaging in healthy dietary behaviours as a means of HIV self-management.
Design:
We conducted semi-structured interviews with PLHIV. We generated codes on food insecurity among PLHIV and used content analysis to organise codes for constant comparison between and within participants.
Setting:
Two urban HIV clinics in the Dominican Republic.
Participants:
Thirty-two PLHIV participated in the interviews.
Results:
Factors that contributed to dietary behaviours include individual factors, such as knowledge of nutrition, views and attitudes on healthy dietary behaviours, beliefs about dietary needs for PLHIV and diet functionality. Interpersonal factors, including assistance from family and peers in providing food or funds, were deemed critical along with community and organisational factors, such as food assistance from HIV clinics, accessibility to a variety of food store types and the availability of diverse food options at food stores. Policy-level factors that influenced dietary behaviours were contingent on respondents’ participation in the labour market (i.e. whether they were employed) and consistent access to government assistance. Food insecurity influenced these factors through unpredictability and a lack of control.
Conclusions:
PLHIV who experience food insecurity face various barriers to engaging in healthy dietary behaviours. Their diets are influenced at multiple levels of influence ranging from individual to structural, requiring multi-level interventions that can address these factors concurrently.
To examine participants’ experiences with nutrition education classes that were implemented with and designed to complement a cost-offset community-supported agriculture (CSA) programme.
Design:
Qualitative analysis of data from twenty-eight focus groups with ninety-six participants enrolled in Farm Fresh Foods for Healthy Kids (F3HK). Transcribed data were coded and analysed by a priori and emergent themes.
Setting:
Rural and micropolitan communities in New York, North Carolina, Vermont and Washington (USA).
Participants:
Ninety-six F3HK participants.
Results:
Participants found recipes and class activities helpful and reported improvements in nutrition knowledge, food preservation skills and home cooking behaviours for themselves and their children; they also reported that classes promoted a sense of community. Some educators better incorporated CSA produce into lessons, which participants reported as beneficial. Other obligations and class logistics were barriers to attendance; participants recommended that lessons be offered multiple times weekly at different times of day. Other suggestions included lengthening class duration to encourage social engagement; emphasising recipes to incorporate that week’s CSA produce and pantry staples and offering additional strategies to incorporate children in classes.
Conclusion:
Complementing a cost-offset CSA with nutrition education may enhance programme benefits to low-income families by improving nutrition knowledge and cooking behaviours. However, future interventions will benefit from ongoing coordination between educators and local growing trajectories to maximise timely coverage of unfamiliar produce in lessons; synchronous scheduling of CSA pick-up and classes for participant convenience and creative strategies to engage children and/or provide childcare.
To compare the effects of a typical Food Distribution Program on Indian Reservations (FDPIR) diet with an FDPIR diet that meets Dietary Guidelines for Americans (DGA) on inflammation response, appetite and energy intake on a combination of American Indian (AI) and non-AI individuals.
Design:
A within-subjects, randomised, crossover design was used to compare two dietary conditions: (1) a FDPIR diet that met DGA and (2) a FDPIR diet that did not meet DGA. Each participant served as their own control and was exposed to both dietary conditions. Repeated-measures ANOVA and t tests assessed significance between the two dietary conditions.
Setting:
This took place in the Montana State University Nutrition Research Laboratory in the USA.
Participants:
Female and male participants (n 13) aged 18–55 years from the university and local community.
Results:
There were no significant differences in inflammatory response and appetite sensations between the two dietary conditions. Findings indicated that participants ate 14 % more (P < 0·01) kcal on a typical FDPIR diet compared with a FDPIR diet that met DGA.
Conclusions:
Higher energy intake during a typical FDPIR diet compared with a FDPIR diet that meets DGA may increase risk for obesity and nutrition-related diseases, including type 2 diabetes and other chronic inflammatory conditions.
Inadequate iodine intake during pregnancy increases the risk of neonatal morbidity and mortality. We aimed to evaluate whether prenatal supplements containing iodine affect urinary iodine concentrations (UIC) of pregnant women in Malawi.
Design:
A randomised controlled trial. Pregnant women (n 1391) were assigned to consume 60 mg/d Fe and 400 µg/d folic acid (IFA) or 18 vitamins and minerals including 250 µg/d iodine (MMN) or 20 g/d small-quantity lipid-based nutrient supplements (SQ-LNS) with similar nutrient contents as MMN group, plus macronutrients (LNS) until childbirth. In a sub-study (n 317), we evaluated group geometric mean urinary iodine concentration (UIC) (µg/L) at 36 weeks of gestation controlling for baseline UIC and compared median (baseline) and geometric mean (36 weeks) UIC with WHO cut-offs: UIC < 150, 150–249, 250–499 and ≥500 reflecting insufficient, adequate, above requirements and excessive iodine intakes, respectively.
Setting:
Mangochi District, Malawi.
Participants:
Women ≤20 weeks pregnant.
Results:
Groups had comparable background characteristics. At baseline, overall median (Q1, Q3) UIC (319 (167, 559)) suggested iodine intakes above requirements. At 36 weeks, the geometric mean (95 % CI) UIC of the IFA (197 (171, 226)), MMN (212 (185, 243)) and LNS (220 (192, 253)) groups did not differ (P = 0·53) and reflected adequate intakes.
Conclusions:
In this setting, provision of supplements containing iodine at the recommended dose to pregnant women with relatively high iodine intakes at baseline, presumably from iodised salt, has no impact on the women’s UIC. Regular monitoring of the iodine status of pregnant women in such settings is advisable. Clinicaltrials.gov identifier: NCT01239693.
This study examined the prevalence of stunting-overweight and socio-demographic determinants among children under-five years of age, as well as associations with infant and young child feeding (IYCF) among children aged 6–23 months.
Design:
Secondary data analysis based on the Thailand Multiple Indicator Cluster Survey 2015–2016.
Setting:
Cross-national study.
Participants:
Nationally representative sample of children under-five years of age (n 12 313).
Results:
The prevalence of wasting, stunting, overweight and stunting-overweight was 5·3, 10·5, 10·1 and 1·6 %, respectively. In multivariate analyses, children under 6 months, children from low and middle wealth tertiles, and children living in rural areas were prone to being wasted. Male children, low wealth tertile and a non-Thai speaking household head were positively and children aged 48–59 months and a one-child household were inversely associated with stunting. Children from a low wealth tertile were less likely to be overweight, while older age, male children and children from a one-child household were more likely to be overweight. Stunting-overweight was associated with children aged 24–47 months, male children, mothers having secondary education, a one-child household, a non-Thai speaking household head and an urban area. In terms of IYCF indicators, despite no association with stunting and stunted-overweight children, current breast-feeding and inadequate meal frequency were associated with being wasting, while current breast-feeding and dietary diversity were inversely associated with being overweight.
Conclusions:
This study revealed the double burden of malnutrition at the individual and population levels among Thai children under-five, which calls for concrete integrated interventions to tackle all forms of malnutrition.
Ethiopia recently scaled up the implementation of a school feeding programme (SFP). Yet, evidence on the impact of such programmes on academic outcomes remains inconclusive. We evaluated the effect of the SFP on class absenteeism and academic performance of primary school students (grade 5–8) in Sidama zone, Southern Ethiopia.
Design:
This prospective cohort study enrolled SFP-beneficiary (n 240) and non-beneficiary (n 240) children 10–14 years of age from sixteen public schools and followed them for an academic year. School absenteeism was measured as the number of days children were absent from school in the year. Academic performance was defined based on the average academic score of the students for ten subjects they attended in the year. Data were analysed using multivariable mixed effects negative binomial and linear regression models.
Setting:
Food insecure districts in Sidama zone, Southern Ethiopia.
Participants:
SFP-beneficiary and non-beneficiary children 10–14 years of age.
Results:
The mean (sd) number of days children were absent from school was 4·0 (sd 1·5) and 9·3 (sd 6·0), among SFP beneficiaries and non-beneficiaries, respectively. Students not covered by the SFP were two times more likely to miss classes (adjusted rate ratio = 2·30; 95 % CI 2·03, 2·61). Pertaining to academic performance, a significant but small 2·40 (95 % CI 0·69, 4·12) percentage point mean difference was observed in favour of SFP beneficiaries. Likewise, the risk of school dropout was six times higher among non-beneficiaries (adjusted rate ratio = 6·04; 95 % CI 1·61, 22·68).
Conclusions:
SFP promotes multiple academic outcomes among socio-economically disadvantaged children.
Approximately 25 % of Canadian children aged 4–8 years fail to meet the recommended dietary allowance (RDA) of calcium (Ca). Young children’s food choices are primarily determined by their parents. No interventions have directly targeted parents as a medium through which to increase children’s Ca consumption. This study compared the effectiveness of a Ca-specific intervention targeted towards parents, with generic dietary advice on the Ca consumption of children aged 4–10 years.
Design:
A parallel two-arm randomised controlled trial was conducted.
Setting:
The study was conducted across Canada. Both conditions received information on the RDA of Ca and an index of intake requirements. Material sent to the intervention condition included behavioural strategies to increase dietary Ca consumption, information on the benefits of dietary Ca intake and messages addressing perceived barriers to the consumption of Ca-rich foods.
Participants:
A total of 239 parents (93 % mothers) of children aged 4–10 years who consumed less than the RDA of Ca were randomly assigned in a 1:1 allocation ratio.
Results:
There was a significant increase in total Ca intake and Ca from dairy for children at weeks 8, 34 and 52 (P ≤ 0·001) in both conditions. Parental Ca intake and amount spent on dairy products did not significantly increase following the intervention.
Conclusions:
Provision of daily Ca requirements with regular reminders could impact parents’ delivery of Ca-rich foods to their children. This finding is important for public health messaging as it suggests that parents are a potent medium through which to promote Ca intake in children.
Schools offer an ideal setting for childhood obesity interventions due to their access to children and adolescents. This review aimed to systematically review the impact of school-based intervention for the treatment of childhood obesity.
Design:
Eight databases were searched from inception till 30 May 2020. A revised Cochrane risk-of-bias tool and the Grading of Recommendations, Assessment, Development and Evaluations criteria were used to evaluate the risk of bias and overall evidence. Meta-analysis and meta-regression were performed on Stata software using the random effects model. Overall effect was evaluated using Hedges’ g, and heterogeneity was assessed using Cochran’s Q and I2.
Setting:
Cluster randomised controlled trials (cluster-RCT) delivered in school.
Participants:
Children and adolescents (6–18 years of age) with overweight and obesity.
Results:
Twelve cluster-RCT from seven countries with 1755 participants were included in the meta-analysis. School-based interventions for the treatment of childhood obesity reduced BMI and BMI z-scores with a medium effect (g = 0·52). Subgroup analyses showed greater effectiveness of brief school-based interventions and the interventions conducted in lower-middle to upper-middle economies. Meta-regression assessed the heterogeneity and the final model, with covariates of the type of economies and trial duration, accounted for 41·2 % of the variability. The overall quality of evidence was rated low because of the high risk of bias and inconsistency.
Conclusions:
School-based interventions are a possible approach to provide universal healthcare for the treatment of childhood obesity, and further well-designed cluster-RCT with longer follow-up are needed. This study is registered with PROSPERO (CRD42020160735).
Healthy eating behaviours are often developed early in life, yet nutrition is rarely emphasised in early childhood education. Integration of nutrition into academic content is warranted, still its ability to positively impact teaching and learning has been understudied. Therefore, the current study explored the feasibility of application in the classroom and the perceived usability of a nutrition-integrated pilot curriculum.
Design:
Early childhood teachers’ perceptions of four nutrition-integrated lessons were explored through a qualitative research approach. Data were collected through pre- and post-focus groups, lesson observations and teacher feedback. Focus group transcripts were analysed using inductive thematic analysis and supplemented with observations and lesson feedback.
Setting:
This pilot study took place in Northwest Mississippi at three pre-schools which are part of the Mississippi Early Learning Collaborative.
Participants:
A non-probability convenience sample was utilised to acquire participants. Ten early childhood teachers and 132 Pre-K4 students participated in the study.
Results:
Three themes emerged and were categorised accordingly: (a) preconceived concern of the unknown v. experienced reality, (b) promoting buy-in and engagement through hands-on learning experiences and (c) manifestation of perceived prioritisation.
Conclusions:
Nutrition-integrated lessons were reported to be creative, facilitate positive food behaviours and highly engaging for teachers and children. Concerns for new and unfamiliar curriculum were noted but could be alleviated with more detailed instructions. Future nutrition-integrated curriculum efforts should include detailed video instructions and offer a gradual and flexible schedule allowing teacher autonomy in how to prioritise implementation.
To assess efforts of the Brazilian legislature to regulate ultra-processed food industry practices related to obesity and diet-related non-communicable diseases during the first 4 years of the United Nations’ Decade of Action on Nutrition.
Design:
We searched the Chamber of Deputies and Federal Senate internal databases to identify bills under consideration between 2016 and December 2019. Keywords related to the main recommendations of international organisations regarding the regulation of food industry practices were used. Descriptive and content analysis of the bills were carried out.
Setting:
Brazilian legislature (Chamber of Deputies and Federal Senate).
Participants:
None.
Results:
Eighty-four bills were identified. The most frequently addressed topics were: nutrition labelling (38·1 %), marketing of unhealthy products (30·9 %), availability of unhealthy products (26·2 %) and critical nutrients content (14·3 %). Only 9·5 % of bills have proposed taxation on unhealthy products. No bill was passed during that period; 2·4 % were rejected and 10·7 % archived. Among the bills still under consideration, 52·4 % have not been passed in any Committee.
Conclusions:
Although many bills have been introduced, no regulation of ultra-processed food industry practices has been enacted by the Brazilian legislature by 2020. It is likely that no positive impact on population nutrition in Brazil will be achieved by the end of the United Nation’s Decade of Action on Nutrition, in 2025 – especially regarding those goals set by the Brazilian government which were supposed to have been achieved by 2019.
To analyse the determinants of exclusive breast-feeding (EBF) discontinuation in southeastern Brazil between 2008 and 2013.
Design:
Secondary cross-sectional data were analysed from three waves of child feeding surveys conducted in the city of Marília, São Paulo, Brazil, in 2008, 2011 and 2013 (n 1645 children under 6 months). Multivariable Poisson regression models were used to test the association between EBF discontinuation and socio-economic, demographic and biomedical factors in a pooled sample and within each survey wave.
Setting:
Regionally representative cross-sectional survey from Brazil.
Participants:
The analytical sample included 1645 infants under 6 months old.
Results:
In the pooled sample, 40·7 % of the infants were exclusively breastfed. Between 2008 and 2013, there was a significant increase in C-section (35·1–42·7 %) and pacifier use (41·4–48·8 %). The determinants of EBF discontinuation in the pooled analysis were mothers working outside the home (adjusted prevalence ratio (APR) = 1·10; 95 % CI 1·00, 1·21), first-time mothers (APR = 1·10; 95 % CI 1·01, 1·20), pacifier use (APR = 1·48; 95 % CI 1·36, 1·61) and low birth weight (APR = 1·17; 95 % CI 1·05, 1·32).
Conclusions:
Mothers working outside the home, first-time moms, pacifier use and low birth weight were the factors associated with EBF discontinuation. Evidence-based counselling strategies during antenatal and early postpartum care in primary healthcare are needed to address the modifiable determinants of EBF discontinuation and ultimately to improve its rates in southeastern Brazil.
To understand if, and how, Australian ultra-processed food industry actors use Twitter to influence food and health policy debates and produce a conceptual framework to describe such influence.
Design:
Twitter data of prominent industry actors were defined through purposive sampling and inductively coded to investigate possible influence on food and health policy debates. These are described using descriptive statistics and coded extracts.
Setting:
Australia.
Participants:
Twitter accounts of nine prominent ultra-processed food industry actors, including major trade associations.
Results:
Ultra-processed food industry actors actively used Twitter to influence food and health policy debates. Seven overarching strategies were identified: co-opting public health narratives; opposing regulation; supporting voluntary, co- or self-regulation; engaging policy processes and decision-makers; linking regulatory environments to the need for ongoing profitability; affecting public perceptions and value judgements; and using ignorance claims to distort policy narratives. Each lobbying strategy is underpinned with tactics described throughout and captured in a framework.
Conclusions:
The current study creates a framework to monitor how food industry actors can use social media to influence food and health policy debates. As such, social media appears to be not only an important commercial determinant of health for brand marketing, but also an extension of lobbying practices to reshape public perceptions of corporate conduct and policy-making.
To assess the access to government programmes and their association with food insecurity (FI) in families from quilombolas communities in Brazil.
Design:
An analysis of secondary data from the 2011 Quilombolas Census was performed in Brazilian territories. The Brazilian Household Food Insecurity Measurement Scale (Escala Brasileira de Insegurança Alimentar, EBIA) was used to assess the household FI status. The relationships of governmental programmes with the levels of FI were estimated using logistic regression models.
Setting:
Greater national survey census of food and nutritional security of the recognised Quilombolas Brazilian territories.
Participants:
Totally, 8743 quilombolas families.
Results:
The prevalence of household FI was 86·1 % (moderate/severe FI: 55·9 %, 95 % CI 54·8, 56·9). After adjustment for socio-demographic variables, access to rural development programmes (Food Acquisition Program: OR: 0·6, 95 % CI 0·4, 0·8, P-value < 0·01) and health programmes (Center for Family Health Support: OR: 0·5, 95 % CI 0·5, 0·7, P-value < 0·001) is inversely and significantly associated with moderate/severe FI. The Brazilian conditional cash transfer programme (Bolsa Família) was associated with quilombolas families with moderate/severe levels of FI (OR: 3·3, 95 % CI 2·8, 4·0, P-value < 0·001).
Conclusions:
The prevalence of FI was high among quilombolas families. Despite reduced participation in governmental programmes, rural development, agriculture and conditional cash transfer programmes are fundamental to the autonomy of quilombolas communities. In spite of the low participation, when families are able to access these programmes, the study revealed the importance of these initiatives in reducing the likelihood of severe levels of FI.
The information displayed on the packages of feeding bottles and teats commercialised in Montevideo (Uruguay) was analysed using content analysis with the goal of identifying key marketing practices that may discourage breast-feeding.
Design:
The study was conducted as part of the periodic assessment performed by the Uruguayan government to monitor the marketing of breast milk substitutes. All the feeding bottles and teats sold in forty-four retail outlets selling breast milk substitutes were purchased. The information available on the packages was analysed using content analysis and descriptive statistics.
Setting:
Montevideo, Uruguay.
Results:
A total of 197 feeding bottles and 71 teats were found. The majority of the packages included information to enable caregivers to adequately use the products, including recommended age, instructions on how to use the products and instructions on the use of hygienic practices. However, the packages frequently included information that implied that bottle feeding was equivalent to breast-feeding, particularly from a physiological perspective, or that idealised product use. Idealisations included ability to reduce colic, improvements in the feeding experience and improvements in children’s health, well-being and development. Statements on the superiority of breast-feeding were infrequent.
Conclusions:
The results from the present work showed the high prevalence of marketing practices on the packages of feeding bottles and teats that may discourage breast-feeding. Stricter and more detailed regulations seem necessary to enable caregivers to make informed feeding decisions for infants.
The current study aimed to predict disability-adjusted life years (DALY) rate in Japan through 2040 with plausible future scenarios of fruit intake for neoplasms, cardiovascular diseases (CVD) and diabetes and kidney diseases (DKD).
Design:
Data from National Health and Nutrition Surveys and the Global Burden of Diseases study in 2017 were used. We developed an autoregressive integrated moving average model with four future scenarios. Reference scenario maintains the current trend. Best scenario assumes that the goal defined in Health Japan 21 is achieved in 2023 and is kept constant afterwards. Moderate scenario assumes that the goal is achieved in 2040. Constant scenario applies the same proportion of 2016 for the period between 2017 and 2040.
Setting:
DALY rates in Japan were predicted for the period between 2017 and 2040.
Participants:
Population aged more than than 20 years old.
Results:
In our reference forecast, the DALY rates in all-ages group were projected to be stable for CVD and continue increasing for neoplasms and DKD. Age group-specific DALY rates for these three disease groups were forecasted to decrease, with some exceptions. Among men aged 20–49 years, DALY attributable to CVD differed substantially between the scenarios, implying that there is a significant potential for reducing the burden of CVD by increasing fruit intake at the population level.
Conclusions:
Our scenario analysis shows that higher fruit intake is associated with lower disease burden in Japan. Further research is required to assess which policies and interventions can be used to achieve an increase in fruit intake as modelled in the scenarios of the current study.
To consider the principal effect of an interaction between year (pre- and post-Universal Infant Free School Meals (UIFSM)) and school on pupil’s dietary intakes.
Design:
A repeated cross-sectional survey using dietary data from 2008 to 2009 (pre-) and 2017 to 2018 (post-UIFSM)
Setting:
Two primary schools, NE England.
Participants:
Pupils aged 4–7 years (2008–2009 n 121; 2017–2018 n 87).
Results:
At lunchtime, there was a statistically significant decrease in pupils non-milk extrinsic sugars intake (%E NMEs) pre- to post-UIFSM (mean change –4·6 %; 95 % CI –6·3, –2·9); this was reflected in total diet (–3·8 %; –5·2, –2·7 %). A year and school interaction was found for mean Ca intakes: post-UIFSM pupils in School 2 had a similar mean intake as pre; in School 1 intakes had increased (difference of difference: –120 mg; 95 % CI –179, –62); no reflection in total diet. Post-UIFSM mean portions of yogurt decreased in School 2 and remained similar in School 1 (–0·25; –0·46, –0·04); this was similar for ‘cake/pudding’ and fruit.
Conclusions:
Within the limitations, these findings highlight positives and limitations following UIFSM implementation and demonstrate the role of school-level food practices on pupil’s choices. To facilitate maximum potential of UIFSM, national levers, such as discussions on updating school food standards, including sugars, could consider removing the daily ‘pudding’ option and advocate ‘fruit only’ options 1 d/week, as some schools do currently. Small school-level changes could maximise positive health impacts by decreasing NMEs intake. A more robust evaluation is imperative to consider dietary impacts, equitability and wider effects on schools and families.
