To analyse the cost-effectiveness of Baby-Friendly Hospital Initiative (BFHI) in promoting breast-feeding during the first hour of life (BFFHL) and reducing late neonatal mortality.

Cost-effectiveness economic assessment from the health system perspective, preceded by a prospective cohort of mother–baby followed from birth to 6 months of life. The direct costs associated with two health outcomes were analysed: intermediate end point (BFFHL) and final end point (reduction in late neonatal mortality).

Study was carried out in six hospitals in the city of São Paulo (Brazil), three being Baby-Friendly Hospitals (BFH) and three non-BFH.

Mothers with 24 h postpartum, over 18 years old, single fetus and breast-feeding at the time of the interview were included. Poisson regressions adjusted for maternal age and level of education were estimated to identify factors related to BFFHL and late neonatal mortality. Sensitivity analysis was performed to ensure robustness of the economic assessment.

Cost-effectiveness analysis showed that BFHI was highly cost-effective in raising BFFHL by 32·0 % at lower cost in comparison with non-BFHI. In addition, BFHI was cost-effective in reducing late neonatal mortality rate by 13·0 % from all causes and by 13·1 % of infant mortality rate from infections.

The cost-effectiveness of the BFHI in promoting breast-feeding and reducing neonatal mortality rates justifies the investments required for its expansion within the Brazilian health system.

To evaluate the cost and cost-effectiveness of a farm-to-Special Supplemental Nutrition Programme for Women, Infants and Children (WIC) intervention to promote vegetable intake and the redemption of WIC vouchers for produce purchases at farmers’ markets.

An economic analysis was undertaken using data from a pilot of the intervention. Vegetable intake was assessed with a reflection spectroscopy device (the Veggie Meter® [VM]) and via self-report. Voucher redemption was reported by WIC. Total and per participant intervention costs and cost-effectiveness ratios (expressed as cost per intervention effect) were estimated in 2019 US dollars over a 6-month period from the perspective of the agency implementing the intervention.

A large, urban WIC agency.

Participants were 297 WIC-enrolled adults.

Post-intervention, VM scores, self-reported vegetable intake and voucher redemption were higher in the intervention as compared with the control study group. Over the 6-month period, intervention costs were $31 092 ($194 unit cost per participant). Relative to the control group, the intervention cost $8·10 per increased VM score per participant, $3·85 per increased cup/d of vegetables consumed per participant and $3·29 per increased percentage point in voucher redemption per participant.

Intervention costs and cost-effectiveness ratios compared favourably with those reported for other interventions targeting vegetable intake in low-income groups, suggesting that the programme may be cost effective in promoting vegetable purchases and consumption. As there is no benchmark against which to compare cost-effectiveness ratios expressed as cost per unit of effectiveness, conclusions regarding whether this is the case must await further research.

To understand the different Na menu labelling approaches that have been considered by state and local policymakers in the USA and to summarise the evidence on the relationship between Na menu labelling and Na content of menu items offered by restaurants or purchased by consumers.

Proposed and enacted Na menu labelling laws at the state and local levels were reviewed using legal databases and an online search, and a narrative review of peer-reviewed literature was conducted on the relationship between Na menu labelling and Na content of menu items offered by restaurants or purchased by consumers.

Local and state jurisdictions in the USA

Not applicable.

Between 2000 and 2020, thirty-eight laws – eleven at the local level and twenty-seven at the state level – were proposed to require Na labelling of restaurant menu items. By 2020, eight laws were enacted requiring chain restaurants to label the Na content of menu items. Five studies were identified that evaluated the impact of Na menu labelling on Na content of menu items offered by restaurants or purchased by consumers in the USA. The studies had mixed results: two studies showed a statistically significant association between Na menu labelling and reduced Na content of menu items; three showed no effects.

Data suggest that Na menu labelling may reduce Na in restaurant menu items, but further rigorous research evaluating Na menu labelling effects on Na content of menu items, as well as on the Na content in menu items purchased by consumers, is needed.

Inadequate nutrient intakes have been linked with poor dentition in older adults. The aim of this study was to investigate the associations between the composition of functional tooth units (FTU) and nutrient intakes in older men.

A cross-sectional study with a standardised validated diet history assessment and comprehensive oral health assessments. FTU were categorised by dentition type: (i) Group A (Natural FTU Only), (ii) Group B (Natural and Replaced FTU) and (iii) Group C (No Natural FTU). Attainment of nutrient reference values (NRV) for sixteen micronutrients was incorporated into a micronutrient risk variable, dichotomised ‘good’ (≥ 12) or ‘poor’ (≤ 11), and for seven macronutrients into a macronutrient risk variable, dichotomised ‘good’ (≥ 5) or ‘poor’ (≤ 4).

Subjects selected from the local Sydney geographical areas.

Community-dwelling older men (n 608).

32 % (n 197) of participants were categorised as Group A, 27 % (n 167) as Group B and 40 % (n 244) as Group C. In adjusted logistic regression analysis, being in Group C, compared with Group A, was associated with intakes below NRV recommendations for fibre (OR: 2·30, 95 % CI 1·30, 4·05). Adjusted analysis also showed that men in Group C, compared with Group A, were more likely to have poor intake of macronutrients (OR: 2·00, 95 % CI 1·01, 3·94).

Our study shows statistically significant associations between the composition of FTU and poor macronutrient intakes. Maintaining natural pairs of occluding FTU may be important for attaining adequate nutrient intakes in older men.

To explore impacts of a demonstration garden-based agricultural intervention on agricultural knowledge, practices and production, food security and preschool child diet diversity of subsistence farming households.

Observational study of households new to the intervention or participating for 1 or 5 years. Variables measured were agricultural techniques learned from the intervention and used, agricultural production, household food insecurity (FIS) and child diet diversity (DDS), over one agricultural cycle (during land preparation, growing and harvest months).

Fifteen rural subsistence farming communities in Panama.

Households participating in intervention (n 237) with minimum one preschool child.

After 1 year, participants had more learned and applied techniques, more staple crops produced and lower FIS and higher DDS during land preparation and growing months compared with those new to the intervention. After 5 years, participants grew more maize, chickens and types of crops and had higher DDS during growing months and, where demonstration gardens persisted, used more learned techniques and children ate more vitamin A-rich foods. Variables associated with DDS varied seasonally: during land preparation, higher DDS was associated with higher household durable asset-based wealth; during growing months, with greater diversity of vegetables planted and lower FIS; during harvest, with older caregivers, caregivers working less in agriculture, more diverse crops and receiving food from demonstration gardens.

The intervention improved food production, food security and diets. Sustained demonstration gardens were important for continued use of new agricultural techniques and improved diets.

To analyse the content of the marketing of commercial foods for infants and young children on packages and social media.

Commercial foods targeted at children, regarded as potential breast-milk substitutes according to the Uruguayan breast-feeding standard, were considered: dairy products; teas, juices and bottled waters; glucose solutions; cereals and mixtures of fruits and vegetables. All the products sold at forty-four retail outlets were purchased. A Facebook search was performed to identify accounts of these products. For each account, all the content posted by the brands between July 2017 and July 2019 was recorded. The visual and textual information included in the packages and Facebook posts was analysed using content analysis. Products were classified using the nutrient profile model of the Pan American Health Organization.

Montevideo, Uruguay.

Seventy-six unique commercial foods targeted at infants and young children were identified, 96 % of which were excessive in sugar. Packages frequently included textual and visual elements to convey health-related associations, including images of fruits and vegetables, nutrient content claims and endorsement logos. Ten Facebook accounts were identified, which generated 302 posts. Parents and caregivers were the main target audience of the posts, which mainly included content related to fun and social aspects of food consumption. Additionally, the posts frequently conveyed the idea that products would contribute to children’s growth and development.

Results suggest the need to implement comprehensive regulations on the marketing of commercial foods targeted at children, regarded as potential breast-milk substitutes according to the Uruguayan breast-feeding standard.

To assess the knowledge, opinions and expectations of persons with and without obesity concerning personalised genotype-based nutrition.

Questions about nutrition, weight management and personalised genotype-based dietary recommendations were asked via standardised telephone-based interviews. Sociodemographic and anthropometric data were collected. The data were statistically weighted by age, gender, education, domicile and BMI.

Germany.

Representative sample of the German population (n 1003) randomly sampled via a scientific Random Digit dial method plus 354 adults with a BMI ≥ 30·0 kg/m2 to enlarge the sample.

Data of 1357 participants were analysed (51·1 % female, age: 50·5 ± 18·5 years, 15·9 % adults with a BMI ≥ 30·0 kg/m2). About 42 % or 19 % of the survey participants stated to know the terms personalised dietary recommendation or genotype-based dietary recommendation, respectively. Of those, 15·8 % indicated to have an experience with a personalised or genotype-based dietary recommendation. Almost 70 % of the survey participants believed that a genotype-based dietary recommendation is a reasonable measure for weight management. About 55 % of the survey participants pointed out that a genotype-based dietary recommendation is an effective concept in general. One-third of the survey participants (34·6 %) indicated to conceive the usage of a genotype-based dietary recommendation.

Most of the survey participants did not know the term personalised or genotype-based dietary recommendation. One-third of the study participants are interested to use a genotype-based dietary recommendation. Therefore, more education of the public is necessary to properly help people making informed and serious decisions and assessing commercially available direct-to-consumer genetic tests.

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.

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.

Australia.

Twitter accounts of nine prominent ultra-processed food industry actors, including major trade associations.

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.

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 compare the Mediterranean and Dietary Approaches to Stop Hypertension (DASH) diets in deterring 10-year CVD.

Prospective cohort (n 2020) with a 10-year follow-up period for the occurrence of combined (fatal or non-fatal) CVD incidence (International Classification of Diseases (ICD)-10). Baseline adherence to the Mediterranean and DASH diets was assessed via a semi-quantitative FFQ according to the MedDietScore and DASH scores, respectively.

Attica, Greece.

Two thousand twenty individuals (mean age at baseline 45·2 (sd 14·0) years).

One-third of individuals in the lowest quartile of Mediterranean diet consumption, as compared with 3·1 % of those in the highest quartile, developed 10-year CVD (P < 0·0001). In contrast, individuals in the lowest and highest DASH diet quartiles exhibited similar 10-year CVD rates (n (%) of 10-year CVD in DASH diet quartiles 1 v. 4: 79 (14·7 %) v. 75 (15·3 %); P = 0·842). Following adjustment for demographic, lifestyle and clinical confounding factors, those in the highest Mediterranean diet quartile had a 4-fold reduced 10-year CVD risk (adjusted hazard ratio (HR) 4·52, 95 % CI 1·76, 11·63). However, individuals with highest DASH diet quartile scores did not differ from their lowest quartile counterparts in developing such events (adjusted HR 1·05, 95 % CI 0·69, 1·60).

High adherence to the Mediterranean diet, and not to the DASH diet, was associated with a lower risk of 10-year fatal and non-fatal CVD. Therefore, public health interventions aimed at enhancing adherence to the Mediterranean diet, rather than the DASH diet, may most effectively deter long-term CVD outcomes particularly in Mediterranean populations.

To investigate whether an after-school nutrition education (ASNE) programme can improve the nutrition knowledge and healthy eating behaviour of adolescents from economically disadvantaged families.

One-group pretest and posttest design. Nutrition knowledge and dietary intake were collected using a questionnaire, and anthropometric measurements were measured before and after the intervention. Nine components of healthy eating behaviour were assessed with reference to the Dietary Guideline of Taiwan. Pretest and posttest differences were analysed using generalised estimating equations.

Three after-school programmes in central and southern Taiwan. The ASNE programme comprised three monthly 1-h sessions (20–30-min lecture and 30–40-min interaction).

A total of 153 adolescents aged 10–15 years from economically disadvantaged families (seventy-eight elementary students and seventy-five junior high school students).

Elementary and junior high school students’ nutrition knowledge scores (range 0–6) increased by 0·28 (+ 5·7 %, P = 0·02) and 0·30 points (+ 6·18 %, P = 0·02), respectively, but their fruit intake decreased by 0·36 serving/d (–22·9 %, P = 0·02) and 0·29 serving/d (–18·9 %, P = 0·03), respectively. Junior high school students’ mean snacking frequency and fried food intake dropped to 0·75 d/week (–21·3 %, P = 0·008) and 0·10 serving/d (–28·8 %, P = 0·01), respectively.

Short-term ASNE programmes can increase nutrition knowledge and reduce snacking frequency and fried food intake despite a decrease in fruit intake among adolescents from economically disadvantaged families.

To explore the #SugarTax debate on Twitter to assess actors involved, their connections and the topics being discussed during the implementation and first anniversary of the UK Soft Drink Industry Levy.

The structure of the #SugarTax debate on Twitter was assessed using social network analysis. The actors involved, their connections and the topics of discussion taking place were also explored using content, sentiment and thematic analyses.

Twitter between 2017 and 2019.

Twitter users engaging in discussions relating to the hashtag ‘SugarTax’.

Tweets (n 5366) posted between 5 August 2017 and 7 May 2019 containing #SugarTax were downloaded from Twitter using Network Overview for Discovery and Exploration in Excel. The network included 1883 users, with 686 unique edges and 4679 edges with duplicates. The majority of tweets were negative in sentiment, when assessed by both automatic (64 %, n 141) and manual sentiment analysis (52 %, n 115) methods. Nine key themes were identified and grouped into two groups according to ‘support for a sugar or SSB tax’ or ‘opposition for a sugar or SSB tax’.

Twitter was used as a platform for debating the benefits and limitations of sugar-sweetened beverage taxes. The findings indicate that numerous actors are involved in the debates on Twitter, with advocates and lobbyists using the platform to raise support for their campaigns and reshape public perceptions. The findings and the methods used may be of interest to policymakers as well as to academics and members of the public looking to explore and engage in policy debates.

To determine the implications of international trade and investment agreements (TIA) for national governments’ policy space to restrict the marketing of unhealthy food and beverages to children.

In-depth interviews based on a series of policy scenario ‘vignettes,’ guided by an adapted scenario analysis methodology.

Global.

Nine key informants from relevant sectors, with expertise regarding the intersection of public health nutrition policy, international trade law and international investment law.

Participants consistently identified the relevance of several principles, common to many TIA: non-discrimination, necessity and justification, market access requirements and quantitative restrictions, intellectual property rights and trademark protections and fair and equitable treatment of investors. Two main policy design factors that interact heavily with TIA-related policy space were the framing of objectives and regulatory distinctions drawn. Contextual factors may shape the analysis of TIA-related policy space on a case-by-case basis, while the relative power of the actors and institutions involved in both domestic and international policy spheres may influence whether and how such legal constraints to policy space are activated.

Regulatory marketing restrictions run the risk of incurring challenges under World Trade Organization agreements and other free TIA. However, concerned policymakers should be aware of the difference between theoretical risk, threat of a challenge and realistic initiation and/or loss of a formal dispute. Our findings indicate that there is policy space to adopt significant marketing restrictions, though an understanding of these legal risks and strategic policy design are important.

To assess the access to government programmes and their association with food insecurity (FI) in families from quilombolas communities in Brazil.

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.

Greater national survey census of food and nutritional security of the recognised Quilombolas Brazilian territories.

Totally, 8743 quilombolas families.

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).

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.

To describe the strategies implemented in seventeen Latin American countries for obesity prevention and to provide an overview of their impact.

A thorough search of strategies and their impact was done through an Internet search, governmental webpages, reports and research articles in English, Spanish and Portuguese.

Latin America (not including the Caribbean countries).

Any.

The Ministry of Health is the main oversight for obesity prevention, with six countries having a specific structure for this. Regular obesity monitoring occurs in a few countries, and thirteen countries have a national obesity prevention plan. The main regulations being implemented/designed are front-of-package labelling (sixteen countries), school environment (fifteen countries), school nutrition education (nine countries), promotion of physical activity level (nine countries) and sugar-sweetened beverage tax (eight countries). All countries have dietary guidelines. The main community-based programmes being implemented are school meals (seventeen countries), complementary nutrition (eleven countries), nutrition education (fourteen countries), promotion of physical activity (nine countries) and healthy environments (nine countries). Most of these strategies have not been evaluated. The few with positive results have used a coordinated, multi-disciplinary and multi-sector approach, with legislation and executive-level support.

Important obesity prevention strategies are being implemented in the seventeen Latin American countries included in the present review. However, few have been evaluated to assess their impact on preventing obesity. This information can help assess that actions can be generalised to other countries within the region and can help inform how to prevent obesity in different settings.

To investigate club managers’ and parents’ experiences with food selection at handball halls in order to identify facilitators and barriers to the availability of healthy food.

Individual interviews with club managers (n 6) and focus groups (n 5) with parents (n 21) were conducted. Interviews were recorded and transcribed verbatim, transcripts were coded in NVivo and the analysis was guided by thematic analysis.

Interviews were conducted at five handball clubs with varying socio-economic user populations and sizes in the area of Oslo, Norway.

The club managers were responsible for food selection at the handball clubs. The participating parents had one or two active children between the ages of 6 and 12 years who took part in the clubs.

The club managers and parents generally described food selection at the handball halls as unhealthy and wanted a healthier selection of food. The club managers’ primary barriers to providing a healthier food selection included the potential to lose profits, limited facilities and time to prepare these foods. The parents often valued unhealthy food, as they believed that it supported the social environment and served as a reward for the children. Trainers were perceived as important role models for the promotion of healthy eating. The participants thought that national guidelines could facilitate healthy food environments in sports arenas.

Healthier food options in sports settings could be facilitated through national guidelines that describe healthy foods and establish who is responsible for providing healthy food selections.

To examine associations between sociodemographic and mental health characteristics with household risk for food insecurity during the COVID-19 outbreak.

Cross-sectional online survey analysed using univariable tests and a multivariable logistic regression model.

The United States during the week of 30 March 2020.

A convenience sample of 1965 American adults using Amazon’s Mechanical Turk platform. Participants reporting household food insecurity prior to the pandemic were excluded from analyses.

One thousand two hundred and fifty participants reported household food security before the COVID-19 outbreak. Among this subset, 41 % were identified as at risk for food insecurity after COVID-19, 55 % were women and 73 % were white. On a multivariable analysis, race, income, relationship status, living situation, anxiety and depression were significantly associated with an incident risk for food insecurity. Black, Asian and Hispanic/Latino respondents, respondents with an annual income <$100 000 and those living with children or others were significantly more likely to be newly at risk for food insecurity. Individuals at risk for food insecurity were 2·60 (95 % CI 1·91, 3·55) times more likely to screen positively for anxiety and 1·71 (95 % CI 1·21, 2·42) times more likely to screen positively for depression.

An increased risk for food insecurity during the COVID-19 pandemic is common, and certain populations are particularly vulnerable. There are strong associations between being at risk for food insecurity and anxiety/depression. Interventions to increase access to healthful foods, especially among minority and low-income individuals, and ease the socioemotional effects of the outbreak are crucial to relieving the economic stress of this pandemic.

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.
