To test a culturally tailored obesity prevention intervention in low-income, minority preschool age children.

A three-group clustered randomised controlled trial.

Twelve Head Start centres were randomly assigned to a centre-based intervention, a combined centre- and home-based intervention, or control using a 1:1:1 ratio. The centre-based intervention modified centre physical activity and nutrition policies, staff practices, and child behaviours, while the home-based intervention supported parents for obesity prevention at home.

The primary end point was change in children’s BMI (kg/m2) at post-test immediately following completion of the 8-month intervention. Secondary end points included standardised scores for BMI (BMIz) and body weight (WAZ), and BMI percentiles (BMI pctl).

Three-year-old children enrolled in Head Start in San Antonio, Texas, with written parent consent (n 325), 87 % Latino, 57 % female with mean age (sd) of 3·58 years (0·29).

Change in BMI at post-test was 1·28 (0·97), 1·28 (0·87) and 1·41 (0·71) in the centre + home-based intervention, centre-based intervention and control, respectively. There was no significant difference in BMI change between centre + home-based intervention and control or centre-based intervention and control at post-test. BMIz (adjusted difference –0·12 (95 % CI, –0·24, 0·01), P = 0·06) and WAZ (adjusted difference, –0·09 (–0·17, –0·002), P = 0·04) were reduced for children in centre + home-based intervention compared with control group.

There was no reduction in BMI at post-test in children who received the intervention. Findings shed light on methodological challenges in childhood obesity research and offer future directions to explore health equity-oriented obesity prevention.

This study aimed to examine the impact of different dietary patterns on stroke outcomes among type 2 diabetes mellitus (T2DM) patients in China.

Participants were enrolled by a stratified random cluster sampling method in the study. After collecting dietary data using a quantified FFQ, latent class analysis was used to identify dietary patterns, and propensity score matching was used to reduce confounding effects between different dietary patterns. Binary logistic regression and conditional logistic regression were used to analyse the relationship between dietary patterns and stroke in patients with T2DM.

A cross-sectional survey available from December 2013 to January 2014.

A total of 13 731 Chinese residents aged 18 years or over.

Two dietary patterns were identified: 61·2 % of T2DM patients were categorised in the high-fat dietary pattern while 38·8 % of patients were characterised by the balanced dietary pattern. Compared with the high-fat dietary pattern, the balanced dietary pattern was associated with reduced stroke risk (OR = 0·63, 95 %CI 0·52, 0·76, P < 0·001) after adjusting for confounding factors. The protective effect of the balanced model did not differ significantly (interaction P > 0·05).

This study provides sufficient evidence to support the dietary intervention strategies to prevent stroke effectively. Maintaining a balanced dietary pattern, especially with moderate consumption of foods rich in quality protein and fresh vegetables in T2DM patients, might decrease the risk of stroke in China.

Mixed evidence exists on the impact of beef consumption on cognition. The goal was to create an evidence map capturing studies assessing beef consumption and cognition to reveal gaps and opportunities in the body of literature.

A scoping review was conducted to locate studies up to March 2022 using PubMed and backwards citation screening. Data were extracted by two independent reviewers with conflict resolution, and a database was created and made publicly available.

Intervention and observational studies.

Humans of any age, sex and/or health status, without moderate to severe cognitive impairment and/or abnormalities.

Twenty-two studies were identified that quantified beef or red meat intake and assessed cognition. Six studies assessed beef intake, with the remaining studies describing intake of red meat that may or may not include beef. Nine articles described randomised controlled trials (RCT), mostly conducted in children. Thirteen described observational studies, primarily conducted on adults and seniors. The most common cognitive domains measured included intelligence and general cognition, and memory. The majority of controlled studies were rated with high risk of bias, with the majority of observational trials rated with serious or greater risk of bias.

Red meat and beef intake and cognition is largely understudied. There is a significant lack of replication across study designs, populations, exposures and outcomes measured. The quality of the research would be considerably enhanced by focused assessments of beef intake (and not red meat in general) and specific cognitive domains, along with improved adherence to reporting standards.

Although food environments have been highlighted as potentially effective targets to improve population diets, evidence on Mediterranean food environments is lacking. We examined differences in food availability and affordability in Madrid (Spain) by store type and area-level socio-economic status (SES).

Cross-sectional study. Trained researchers conducted food store audits using the validated Nutrition Environment Measures Survey in Stores for Mediterranean contexts (NEMS-S-MED) tool to measure the availability and price of twelve food groups (specific foods = 35). We computed NEMS-S-MED scores and summarised price data with a Relative Price Index (RPI, comparing prices across stores) and an Affordability Index (normalising prices by area-level income). We compared the availability and affordability of ‘healthier–less healthy’ food pairs, scores between food store types (supermarkets, specialised, convenience stores and others) and area-level SES using ANOVA and multi-level regression models.

City of Madrid. 2016 and 2019 to cover a representative sample.

Food stores within a socio-economically diverse sample of sixty-three census tracts (n 151).

Supermarkets had higher food availability (37·5/49 NEMS-S-MED points), compared to convenience stores (13·5/49) and specialised stores (8/49). Supermarkets offered lower prices (RPI: 0·83) than specialised stores (RPI: 0·97) and convenience stores (RPI: 2·06). Both ‘healthy’ and ‘less healthy’ items were more available in supermarkets. We found no differences in food availability or price by area-level SES, but affordability was higher in higher-income areas.

Supermarkets offered higher food availability and affordability for healthy and less healthy food items. Promoting healthy food availability through supermarkets and specialised stores and/or limiting access to convenience stores are promising policy options to achieve a healthier food environment.

Investigate protein intake patterns over the day and their association with total protein intake in older adults.

Cross-sectional study utilising the dietary data collected through two non-consecutive, dietary record-assisted 24-h recalls. Days with low protein intake (n 290) were defined using the RDA (<0·8 g protein/kg adjusted BW/d). For each day, the amount and proportion of protein ingested at every hour of the day and during morning, mid-day and evening hours was calculated. Amounts and proportions were compared between low and high protein intake days and related to total protein intake and risk of low protein intake.

Community.

739 Dutch community-dwelling adults ≥70 years.

The mean protein intake was 76·3 (sd 0·7) g/d. At each hour of the day, the amount of protein ingested was higher on days with a high protein intake than on days with a low protein intake and associated with a higher total protein intake. The proportion of protein ingested during morning hours was higher (22 v. 17 %, P < 0·0001) on days with a low protein intake, and a higher proportion of protein ingested during morning hours was associated with a lower total protein intake (P < 0·0001) and a higher odds of low protein intake (OR 1·04, 95 % CI 1·03, 1·06). For the proportion of protein intake during mid-day or evening hours, opposite but weaker associations were found.

In this sample, timing of protein intake was associated with total protein intake. Additional studies need to clarify the importance of these findings to optimise protein intake.

Certain factors, such as food quality, label content and grocery characteristics, may be considered when purchasing foods. Food availability in the home has been shown to influence dietary behaviours, also associated with delay discounting (DD). The present study sought to characterize the relationships between DD, food purchasing considerations and healthfulness of foods in the home.

A cross-sectional, online survey of adults (n 477) was conducted with the following measures: DD, consideration of food quality (nutrition, taste) and grocery characteristics (price, ease of preparation, shelf-life) while shopping, use of food labels and food availability in the home. DD was assessed by the area under the delay discounting curve (AUC) using a binary choice task. Greater AUC reflects lower DD. Structural equation modelling was used to allow AUC to simultaneously predict purchasing considerations and foods in the home.

Adult employees in south-east Alabama, USA.

DD was negatively associated with food label use and emphasis on food quality when shopping (P<0·001). In the final model, DD was associated with availability of healthful foods in the home and emphasis on food quality and grocery characteristics. About 33 % of the variance in shopping behaviours, 5 % in food label use, 7 % in availability of healthful foods and 4 % in availability of unhealthful foods was explained by DD.

Individuals with lower DD appear to be more thoughtful in making food purchasing decisions and have healthful foods available in the home more frequently than individuals with higher DD.

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.

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.

Quebec, Canada.

Key policy actors including nutritionists.

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.

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.

To evaluate the inclusion and exclusion of nutritional content in guidance materials related to nutritional care for hospitalised Ebola Virus Disease (EVD) patients of any age with the aim to provide recommendations for future revised nutritional care guidelines in Ebola Treatment Units (ETU).

Qualitative and quantitative analyses of ETU protocols and other guidance materials were conducted. Materials were obtained from practitioners, their organisations and governments active in EVD outbreaks since 2014.

Guinea, Liberia, Sierra Leone and Democratic Republic of Congo.

Guidance materials showed a wide variety of topics. Most contained information on different feeding phases during illness, the use of specialised products, what and how to feed children aged 0–23 months, and meal and snack frequency for different age groups. Most materials lacked guidance on how to assess or accommodate patients’ dietary preferences, how to obtain feedback on nutritional care from patients or how to assess whether patients need feeding support. These aspects are particularly relevant to prevent deterioration of the patients’ nutritional status. There was limited guidance on operational aspects of food preparation and provision.

Since 2014, numerous materials have been developed by organisations and governments on nutritional support in ETU. Although every EVD outbreak response must be contextualised because of the complexity of EVD and its case management, it is important to resolve technical differences and to provide comprehensive and more practical guidance. The findings of this study may inform future revised guidelines from normative UN organisations and governments of countries affected by EVD.

To identify predictors of recovery in children with uncomplicated severe acute malnutrition (SAM).

This is a secondary data analysis from an individual randomised controlled trial, where children with uncomplicated SAM were randomised to three feeding regimens, namely ready-to-use therapeutic food (RUTF) sourced from Compact India, locally prepared RUTF or augmented home-prepared foods, under two age strata (6–17 months and 18–59 months) for 16 weeks or until recovery. Three sets of predictors that could influence recovery, namely child, family and nutritional predictors, were analysed.

Rural and urban slum areas of three states of India, namely Rajasthan, Delhi and Tamil Nadu.

In total, 906 children (age: 6–59 months) were analysed to estimate the adjusted hazard ratio (AHR) using the Cox proportional hazard ratio model to identify various predictors.

Being a female child (AHR: 1·269 (1·016, 1·584)), better employment status of the child’s father (AHR: 1·53 (1·197, 1·95)) and residence in a rental house (AHR: 1·485 (1·137, 1·94)) increased the chances of recovery. No hospitalisation (AHR: 1·778 (1·055, 2·997)), no fever, (AHR: 2·748 (2·161, 3·494)) and ≤ 2 episodes of diarrhoea (AHR: 1·579 (1·035, 2·412)) during the treatment phase; availability of community-based peer support to mothers for feeding (AHR: 1·61 (1·237, 2·097)) and a better weight-for-height Z-score (WHZ) at enrolment (AHR: 1·811 (1·297, 2·529)) predicted higher chances of recovery from SAM.

The probability of recovery increases in children with better WHZ and with the initiation of treatment for acute illnesses to avoid hospitalisation, availability of peer support and better employment status of the father.

Breast-feeding rates are unsatisfactory in Lebanon. Social media groups could play an important role in promoting breast-feeding in normal conditions and post crisis. The aim of this study is to identify breast-feeding challenges, facilitators and assets and to describe how community assets via social media could build community resilience to pandemic’s and disaster’s effects.

A two-phase qualitative content analysis was performed on posts and comments collected from a Facebook breast-feeding support group. Data were categorised into themes, categories and subcategories.

Posts and comments retrieved from a Facebook breast-feeding support group in Lebanon during the month of August 2020.

Group members: mothers who breastfed, breast-feeding mothers and group admins that are lactation consultants.

In phase one, breast-feeding ‘Challenges’ identified were lack of support from peers and family, lack of supportive policies, lack of knowledge and maternal stress related to political instability, COVID-19 and economic crisis. ‘Assets and facilitators’ included community support and donations. In phase two, analysis revealed how assets were being used on social media platform to build community resilience post crisis, through access to social support in challenging times, community engagement, material resources and transformative potential.

Challenges faced during breast-feeding were diminished due to the support and assets received on a Facebook breast-feeding support group, and social media has been shown to be an important community asset implicated in empowering women to breastfeed and to build community resilience in moments of crisis.

To examine patterns of taxed and untaxed food and beverage shopping across store types after Mexico’s sugary drink and non-essential food taxes, the nutritional quality of these patterns and the socio-economic characteristics associated with them.

We performed k-means cluster analyses using households’ percentage of food and beverage purchases from each store type (i.e. convenience stores, traditional shops (e.g. bodegas, tiendas, mom-and-pop shops), supermarkets, wholesalers and others). We calculated adjusted mean proportions of taxed and untaxed products (ml or g/capita per d) purchased in each pattern. We studied the associations between households’ SES and shopping patterns using multinomial logistic regressions. Within shopping patterns, we obtained mean volumes and proportions of taxed and untaxed food and beverage subgroups and calculated the proportion of products purchased at each store type.

Mexico.

Urban Mexican households (n 5493) from the Nielsen Mexico Consumer Panel Survey 2015.

We found four beverage shopping patterns and three food shopping patterns, driven by the store type where most purchases were made. For beverages, 48 % of households were clustered in the Traditional pattern and purchased the highest proportion of taxed beverages. Low-SES households had the highest probability of clustering in the Traditional beverage shopping pattern. For foods, 35 % of households were clustered into the Supermarket pattern. High-SES households had the highest probability of clustering in the Supermarket food shopping pattern.

The combination of store types where Mexican households purchase packaged foods and beverages varies. However, households in all shopping patterns and SES purchase taxed beverages mainly at traditional stores. Store-level strategies should be developed to intervene on traditional stores to improve the healthfulness of purchases.

Efficacy studies show early nutrition interventions improving infant nutrition status, but understanding caregiver acceptability is required for implementation of such interventions. This systematic review examines caregivers’ perceptions of nutrition interventions in young children.

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL and PsychINFO from date of online journal inception through December 2020. Interventions included oral (powder/liquid/tablet) and/or intravenous supplementation, food fortification and nutrition counselling. Inclusion criteria included primary research, data presented on caregiver perception and studies published in English. Quality assessment was performed using the Critical Appraisal Skills Programme tool. Studies underwent narrative synthesis using inductive thematic analysis.

No restriction.

Caregivers of children under 24 months of age.

Of 11 798 records identified, thirty-seven publications were included. Interventions included oral supplementation, food fortification and nutrition counselling. Caregivers included mothers (83 %), fathers, grandparents and aunts. Perceptions were gathered through individual interviews, focus group discussions, questionnaires, surveys and ratings. Totally, 89 % of studies noted high acceptability (n 33 most notably increased appetite (n 17). In total, 57 % of studies (n 21) cited low acceptability, commonly from side effects (n 13) such as gastrointestinal issues, appetite loss and stained teeth.

Positive perceptions and enthusiasm for interventions were frequently reported. Key to implementation was the increased appetite noted by caregivers. A substantial proportion of studies reported negative perceptions, mainly due to side effects. In future interventions, mitigation and education around common side effects are crucial for acceptability. Understanding both positive and negative caregiver perceptions is important for informing future nutrition interventions and strengthening sustainability and implementation.

To compare the prognostic value of mid-upper arm circumference (MUAC), weight-for-height Z-score (WHZ) and weight-for-age Z-score (WAZ) for predicting death over periods of 1, 3 and 6 months follow-up in children.

Pooled analysis of twelve prospective studies examining survival after anthropometric assessment. Sensitivity and false-positive ratios to predict death within 1, 3 and 6 months were compared for three individual anthropometric indices and their combinations.

Community-based, prospective studies from twelve countries in Africa and Asia.

Children aged 6–59 months living in the study areas.

For all anthropometric indices, the receiver operating characteristic curves were higher for shorter than for longer durations of follow-up. Sensitivity was higher for death with 1-month follow-up compared with 6 months by 49 % (95 % CI (30, 69)) for MUAC < 115 mm (P < 0·001), 48 % (95 % CI (9·4, 87)) for WHZ < -3 (P < 0·01) and 28 % (95 % CI (7·6, 42)) for WAZ < -3 (P < 0·005). This was accompanied by an increase in false positives of only 3 % or less. For all durations of follow-up, WAZ < -3 identified more children who died and were not identified by WHZ < -3 or by MUAC < 115 mm, 120 mm or 125 mm, but the use of WAZ < -3 led to an increased false-positive ratio up to 16·4 % (95 % CI (12·0, 20·9)) compared with 3·5 % (95 % CI (0·4, 6·5)) for MUAC < 115 mm alone.

Frequent anthropometric measurements significantly improve the identification of malnourished children with a high risk of death without markedly increasing false positives. Combining two indices increases sensitivity but also increases false positives among children meeting case definitions.
