A high-fibre diet is associated with a lower risk for diseases. However, few adults meet the dietary fibre recommendation. Therefore, the effects and acceptance of an algorithm-generated personalised dietary advice (PDA) compared with general advice (GA) on fibre intake were investigated.

A 6-week, single-blind randomised controlled trial with a 3-month follow-up.

PDA was based on habitual intake and provided fibre-rich alternatives using a website; GA contained brochures. Dietary intake was assessed at baseline, week 1, week 6 and 3-month follow-up. Both groups evaluated their advice at week 6. All participants had access to PDA from week 7 until 3-month follow-up.

Two groups of healthy adults: PDA (n 34) and GA (n 47). For 3-month follow-up analysis, participants were re-divided into visitors (n 52) and non-visitors (n 26) of the PDA.

At week 6, energy intake remained stable in both groups, but fibre intake per 1000 kcal increased non-significantly in both groups (PDA = Δ0·5 ± 2·8; GA = Δ0·8 ± 3·1, P = 0·128). Importantly, a significantly higher percentage of PDA participants adhered to the recommendation compared with week 1 (PDA = 21 % increase; GA = 4 % increase, P ≤ 0·001). PDA participants evaluated the advice significantly better compared with GA participants. At 3-month follow-up, fibre intake increased compared with baseline (visitors = Δ2·2 ± 2·6, P < 0·001; non-visitors = Δ1·5 ± 1·9, P = 0·001), but was insignificantly different between groups. Visitors had a decrease and non-visitors had an increase in energy intake (visitors =Δ − 132 ± 525; non-visitors = Δ109 ± 507, P = 0·055).

The algorithm-generated PDA was well accepted and stimulated adherence to the recommendations more than GA, indicating to be a suitable and cost-efficient method for improving dietary fibre intake in healthy adults.

Elevated BMI is associated with multiple chronic conditions including diabetes and CVD. Patients with overweight or obesity may also suffer from comorbidities not directly related to the pathophysiology of elevated BMI. The current study sought to determine the impact of BMI and different types of chronic conditions on health-related quality of life (HRQoL) outcomes.

Six weight categories by BMI were identified: underweight, normal weight, overweight, Class-I obesity, Class-II obesity and Class-III obesity. Twenty chronic conditions were considered and categorised as elevated BMI-related (concordant) or -unrelated (discordant) conditions. HRQoL outcomes were measured using Short Form-6 Dimensions (SF-6D). Multivariable regression models were performed to examine the impact of type, number of comorbid conditions and BMI categories on SF-6D scores.

Medical Expenditure Panel Survey (2013–2015).

Nationally representative sample of US population; 18 years or older (n 58 960).

Of the sample, 1·7 %, 32·9 %, 34·0 % and 31·4 % were classified as underweight, normal weight, overweight and obese, respectively. The SF-6D scores were significantly decreased across all obesity classes, with the largest reduction in Class-III obesity (0·033; P < 0·001). Additionally, individuals with obesity having one or more concordant or discordant comorbidities further reduced SF-6D scores between 0·031 and 0·148 (P-values < 0·001) or between 0·080 and 0·212 (P-values < 0·001), respectively.

Individuals with obesity had a significant reduction in HRQoL outcomes compared to those with normal BMI. Importantly, discordant comorbidity resulted in greater reduction in HRQoL outcomes compared to concordant comorbidity in subjects with elevated BMI.

There is a lack of qualitative research developing sugar-sweetened beverage (SSB) warning labels with their intended end users. We sought to identify promising SSB warning elements for improving label effectiveness and for future testing in policy and institutional settings.

Mixed methods design using ten focus groups, a design task and a survey. The design task was used to generate ideas for an icon that would dissuade SSB consumption. The survey and focus group guide assessed participant perceptions of SSB warning label mock-ups of text (loss frame, gain frame and loss frame with attribution), colour and icon options.

Three large public universities in California from February to March 2018.

Young adult SSB consumers (n 86) enrolled in one of three diverse California public universities.

Participants perceived the following elements as most effective for reducing SSB consumption: loss-frame text with attribution to a credible source, yellow and red colour for label background and an image or icon to accompany the text. Preferred images included sugar near or inside of an SSB, intuitive shapes like a triangle with exclamation mark or octagon and a visual indicator of SSB sugar content compared with recommended limits. Support was high for using SSB warning labels in university cafeterias and on bottles/cans.

Loss-frame text with a credible source, yellow or red label colour and icons could potentially enhance effectiveness of SSB warning labels and warrant further testing.

To examine the prevalence of and factors associated with different forms of household-level double burden of malnutrition (DBM) in Ethiopia.

We defined DBM using anthropometric measures for adult overweight (BMI ≥ 25 kg/m2), child stunting (height-for-age Z-score <-2 sd) and overweight (weight-for-height Z-score ≥2 sd). We considered sixteen biological, environmental, behavioural and socio-demographic factors. Their association with DBM forms was assessed using generalised linear models.

We used data from two cross-sectional studies in an urban (Addis Ababa, January–February 2018), and rural setting (Kersa District, June–September 2019).

Five hundred ninety-two urban and 862 rural households with an adult man, adult woman and child <5 years.

In Addis Ababa, overweight adult and stunted child was the most prevalent DBM form (9 % (95 % CI 7, 12)). Duration of residence in Addis Ababa (adjusted OR (aOR) 1·03 (95 % CI 1·00, 1·06)), Orthodox Christianity (aOR 1·97 (95 % CI 1·01, 3·85)) and household size (aOR 1·24 (95 % CI 1·01, 1·54)) were associated factors. In Kersa, concurrent child overweight and stunting was the most prevalent DBM form (11 % (95 % CI 9, 14)). Housing quality (aOR 0·33 (95 % CI 0·20, 0·53)), household wealth (aOR 1·92 (95 % CI 1·18, 3·11) and sanitation (aOR 2·08 (95 % CI 1·07, 4·04)) were associated factors. After adjusting for multiple comparisons, only housing quality remained a significant factor.

DBM prevalence was low among urban and rural Ethiopian households. Environmental, socio-economic and demographic factors emerged as potential associated factors. However, we observed no common associated factors among urban and rural households.

Identify and characterise the food industry’s involvement in nutrition and dietetics national and regional events in Latin America and the Caribbean.

Between February and April 2020, we conducted desk-based searches for nutrition and dietetics events held in the region between January 2018 and December 2019. Online freely accessible, publicly available information was collected on the involvement of the food industry through: sponsorship of events; sponsorship of sessions; speakers from the food industry; scholarships, fellowship, grants, awards and other prizes and; exhibition space/booths.

Nutrition and dietetics events in Latin America and the Caribbean.

Thirty-one events held in twenty countries of the region had information publicly available online at the period of data collection. There was a lack of transparency on the involvement of industry actors in these events. When information was publicly available, we found that a total of ninety-two food industry actors sponsored 88 % of these events.

There is a mostly unreported, but likely extensive, involvement of food industry actors in nutrition and dietetics events in Latin America and the Caribbean.

The excessive growth of the food supplements’ industry highlights the need to focus attention on all aspects involved in their proper consumption; one that takes centre stage is advertising. The aim of this research is to analyse the presence of false and misleading claims in food supplements advertising. To this end, a relationship is established between the different types of health-related claims and the substances on which they are based, whether authorised or not by European Food Safety Authority (EFSA).

This empirical work conducts a content analysis of all radio mentions broadcast throughout 2017 on news/talk radio stations.

Spain.

All radio mentions broadcast on news/talk commercial radio stations in Spain with the highest audience levels. The corpus is composed of 437 advertisements.

Results indicate that 80·3 % of function claims included in the analysed advertisements are not authorised by EFSA, while 20·4 % of disease claims are not allowed by EU regulation. Likewise, almost half of the substances referred to (43·7 %) are illicit: 54·1 % in function claims, 57·3 % in disease claims and 73·7 % in the case of reduction of disease risk claims.

This work reveals consistent failures to comply with European regulation on food supplements advertising. The widespread use of unauthorised health claims and substances is aggravated by the indirect recourse of illness as a persuasive argument, descriptions of alleged benefits as product attributes and the omission of essential information. This leads to dangerous misinformation and can pose serious health risks. Stronger legal mechanisms are needed for effective consumer protection.

To evaluate if the inclusion of nutritional warnings in food ordering websites can discourage consumers from purchasing foods with excessive content of nutrients associated with non-communicable diseases (NCD).

Participants were randomly assigned to one of the two experimental conditions: control (n 225) or nutritional warnings (n 222). Nutritional warnings corresponded to separate black octagonal signs containing the word ‘Excess’ followed by the corresponding nutrient: total fat, saturated fat, sugars and sodium. Participants were asked to purchase a lunch for themselves using a simulated food ordering website.

Online study in Uruguay.

Convenience sample of 447 Uruguayan participants, recruited using social media.

In the control condition, 76 % of the participants selected a dish or a beverage with excessive content of at least one nutrient in the simulated food ordering website. When nutritional warnings were included, this percentage significantly decreased to 62 % (P = 0·002). In addition, nutritional warnings caused a significant reduction in the percentage of participants who selected dishes with excessive content of total fat: 50 % v. 62 % (P = 0·012).

Results from the present work provide preliminary evidence that the inclusion of nutritional warnings in food ordering websites could discourage consumers from selecting dishes and beverages with excessive content of nutrients associated with NCD.

To evaluate the hypothesis that a perinatal educational dietary intervention focused on ‘eating for the gut microbiota’ improves diet quality of pregnant women pre- and postnatally.

The Healthy Parents, Healthy Kids study is a prospectively registered randomised controlled trial designed to evaluate the efficacy of a dietary intervention in altering the maternal and infant gut microbiota and improving perinatal diet quality. Eligible pregnant women were randomised to receive dietary advice from their healthcare provider or to additionally receive a three session dietary intervention. Dietary data were collected at gestation weeks 26, 31, 36 and postnatal week 4. Outcome measures were diet quality, dietary variety, prebiotic and probiotic food intakes, energy, fibre, saturated fat and discretionary food intakes. Between-group differential changes from baseline before and after birth in these dietary measures were assessed using generalised estimating equations.

Melbourne, Australia.

Healthy pregnant women from gestation week 26.

Forty-five women were randomised (twenty-two control, twenty-three intervention). Compared with the control group, the intervention group improved diet quality prior to birth (5·66 (95 % CI 1·65, 9·67), Cohen’s d: 0·82 (se 0·33)). The intervention improved dietary variety (1·05 (95 % CI 0·17, 1·94), d: 0·66 (se 0·32)) and increased intakes of prebiotic (0·8 (95 % CI 0·27, 1·33), d: 0·91 (se 0·33)) and probiotic foods (1·05 (95 % CI 0·57, 1·53), d: 1·3(se 0·35)) over the whole study period compared with the control group.

A dietary intervention focused on ‘eating for the gut microbiota’ can improve aspects of perinatal diet quality during and after pregnancy.

To evaluate the effectiveness of a multicomponent intervention (MCI) on children’s dietary diversity and its impact pathway components of children’s food knowledge and healthy food preferences.

A 6-week cluster randomised controlled trial with a MCI consisting of child nutrition education plus family engagement through parental nutrition education, meal preparation and tasting was compared with two groups: single component intervention (SCI) of child nutrition education, and control, conducted during February to July 2018. Preschool centres were randomly assigned to one of the three arms. Children’s food knowledge, healthy food preferences and dietary diversity scores were collected. Intervention effects were analysed using a pre-post analysis and a difference-in-difference model.

Fourteen preschool centres in an urban area of Kurunegala, Sri Lanka.

Child–parent dyads of children aged 4–6 years. Final analyses included 306 (for food knowledge and preferences) and 258 (for dietary diversity) dyads.

MCI significantly influenced the impact pathways to children’s dietary diversity by increasing children’s food knowledge and healthy food preferences scores by 3·76 and 2·79 (P < 0·001), respectively, but not the dietary diversity score (P = 0·603), compared with the control arm. Relative to SCI, MCI significantly improved children’s food knowledge score by 1·10 (P < 0·001), but no significant effects were noted for other outcome variables.

Improved food knowledge and preferences require a positive food environment and time to develop into healthy eating behaviours. Research into dietary diversity should broaden to incorporate the contextual roles of the home and general food environments to more completely understand food choices of children.

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.

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.

Montevideo, Uruguay.

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.

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.

Local governments have integral roles in contributing to public health. One recent focus has been on how local governments can impact community nutrition by engaging food service outlets to improve their food offer. The Healthier Catering Commitment (HCC) is an initiative where London local governments support takeaways and restaurants to meet centrally defined nutrition criteria on their food options. Using the case of HCC, the current study aims to provide (1) practical learnings of how local governments could facilitate and overcome barriers associated with implementing healthy food service initiatives in general, and (2) specific recommendations for enhancements for HCC.

Key informant, semi-structured interviews were conducted with local government staff involved in HCC, exploring barriers and facilitators to HCC implementation in food businesses. A thematic analysis approach was used, with results presented according to a logic pathway of ideal implementation in order to provide practical, focused insights.

Local governments implementing HCC.

Twenty-two individuals supporting HCC implementation.

Facilitators to implementation included flexible approaches, shared resourcing and strategically engaging businesses with practical demonstrations. Barriers were limited resources, businesses fearing negative customer responses and low uptake in disadvantaged areas. Key suggestions to enhance implementation and impact included offering additional incentives, increasing HCC awareness and encouraging recruited businesses to make healthy changes beyond initiative requirements.

In order to facilitate the implementation of healthy food initiatives in food outlets, local governments would benefit from involving their environmental health team, employing community-tailored approaches and focusing on supporting businesses in disadvantaged areas.

Our objectives were to explore attitudes regarding food retail policy and government regulation among managers of small food stores and examine whether manager views changed due to the 2014 Minneapolis Staple Foods Ordinance, a city policy requiring retailers to stock specific healthy products.

Manager interviewer-administered surveys were used to assess views on food retail policy four times from 2014 to 2017. We examined baseline views across manager and store and neighbourhood characteristics using cross-sectional regression analyses and examined changes over time using mixed regression models. In 2017, open-ended survey questions asked about manager insights on the Minneapolis Staple Foods Ordinance.

Minneapolis, MN, where the ordinance was enacted, and St. Paul, MN, a control community, USA.

Managers from 147 small food retail stores.

At baseline, 48 % of managers were likely to support a policy requiring stores to stock healthy foods/beverages, 67·5 % of managers were likely to support voluntary programmes to help retailers stock healthy foods and 23·7 % agreed government regulation of business is good/necessary. There was a significant increase in overall support for food retail policies and voluntary programmes from 2014 to 2017 (P < 0·01); however, neither increase differed by city, suggesting no differential impact from the ordinance. Minneapolis store managers reported some challenges with ordinance compliance and offered suggestions for how local government could provide support.

Findings suggest that managers of small food retail stores are becoming increasingly amenable to healthy food policies; yet, challenges need to be addressed to ensure healthy food is available to all customers.

To scale-out an experiential teaching kitchen in Parks and Recreation centres’ after-school programming in a large urban setting among predominantly low-income, minority children.

We evaluated the implementation of a skills-based, experiential teaching kitchen to gauge programme success. Effectiveness outcomes included pre–post measures of child-reported cooking self-efficacy, attitudes towards cooking, fruit and vegetable preference, intention to eat fruits and vegetables and willingness to try new fruits and vegetables. Process outcomes included attendance (i.e., intervention dose delivered), cost, fidelity and adaptations to the intervention.

After-school programming in Parks and Recreation Community centres in Nashville, TN.

Predominantly low-income minority children aged 6–14 years.

Of the twenty-five city community centres, twenty-one successfully implemented the programme, and nineteen of twenty-five implemented seven or more of the eight planned sessions. Among children with pre–post data (n 369), mean age was 8·8 (sd 1·9) years, and 53·7 % were female. All five effectiveness measures significantly improved (P < 0·001). Attendance at sessions ranged from 36·3 % of children not attending any sessions to 36·6 % of children attending at least four sessions. Across all centres, fidelity was 97·5 %. The average food cost per serving was $1·37.

This type of nutritional education and skills building experiential teaching kitchen can be successfully implemented in a community setting with high fidelity, effectiveness and organisational alignment, while also expanding reach to low-income, underserved children.

To explore the use of references to the COVID-19 pandemic as part of the marketing strategies used on Facebook to promote ultra-processed products.

A search for Facebook accounts of ultra-processed products was performed using a master list of products commercialised in two online supermarkets in Uruguay. For each of the identified Facebook accounts, all the content posted from the confirmation of the first cases of COVID-19 in Uruguay, on 14 March 2020, until 1 July 2020 was recorded. Posts including mentions to COVID-19, social distancing measures or their consequences were identified and analysed using content analysis.

Uruguay, Latin America.

A total of 135 Facebook accounts were identified, which generated a total of 1749 posts related to ultra-processed products, from which 35 % included references to COVID-19. The majority of the posts included references to prevention measures. Approximately one-third of the posts included proposals of activities to do at home, most of which were linked to a healthy lifestyle. Tips for coping with quarantine and descriptions of the charitable work undertaken by brands were also identified.

Results from the present work provide evidence that industries of ultra-processed products have taken advantage of the COVID-19 pandemic to promote their products, create positive associations with the brands and improve their image as part of their digital marketing strategies.

To assess the feasibility of implementation and customer perspectives of a sugar-sweetened beverage (SSB) reduction initiative across YMCA Victoria aquatic and recreation centres.

Two data sources were used to assess implementation and customer acceptability. Photo audits were used to assess the type of drinks available for purchase 6 months prior to initiative implementation and 6 months after, in thirty centres. Change in the range of SSB targeted for removal, non-targeted SSB, as well as drinks classified as ‘red’ (limit), ‘amber’ (choose carefully) and ‘green’ (best choice), was reported. Customer surveys were conducted in three centres to assess acceptability and awareness of the initiative. Inductive and deductive thematic analysis was used to analyse customers’ perspectives of the initiative.

30 aquatic and recreation centres in Victoria, Australia.

806 customers.

At post-implementation, 87 % of centres had removed targeted SSB. ‘Red’ drinks reduced by an average of 4·4 drink varieties compared to pre-implementation (11·9 varieties) and ‘green’ drinks increased by 1·4 varieties (3·2 varieties pre-implementation). Customers were largely unaware of the SSB-reduction initiative (90 %) but supported YMCA Victoria in continuing the initiative (89 %), with many believing it would support children in making healthier choices.

Implementation of an initiative that limited SSB availability across a large number of aquatic and recreation centres was feasible and considered acceptable by customers. Customers frequently mentioned the importance of protecting children from consuming SSB.
