To examine differences in fruit and vegetable intake and food insecurity between Black African and Caribbean and South Asian (Indian, Pakistani and Bangladeshi) ethnic minority groups with a White British/Irish reference population in the UK. This study was part of the TANGERINE project (nuTritional heAlth aNd aGeing in oldER ethnIc miNoritiEs).

Longitudinal analysis using multilevel logistic regression from Understanding Society and a cross-sectional comparison with UK Biobank.

Understanding Society waves 2 (2010–2012), 5 (2013–2015), 7 (2015–2017), 9 (2017–2019) 11 (2019–2021) and 13 (2021–2023). UK Biobank baseline data (2006–2010).

Understanding Society: adults aged 16 years and above (approximately 44 000 households). UK Biobank: participants aged 37–73 years (n = 502 412).

At wave 2, African, Caribbean, Pakistani and Bangladeshi participants in Understanding Society had lower odds of daily vegetable intake than White British/Irish participants, with Pakistanis showing the lowest intake. These disparities persisted after adjusting for socio-economic position (SEP) at individual and area levels, particularly for Caribbean and Pakistani groups. Indians consistently had higher odds of vegetable intake. Ethnic differences in fruit intake were smaller and largely attenuated by SEP adjustment. Food insecurity was more prevalent in all ethnic minority groups (except Indians) and associated with lower vegetable and fruit intake, though SEP explains more of the ethnic difference.

Ethnic differences in fruit and vegetable intake are at least partially explained by SEP, with persistent vegetable consumption disparities after adjustment. Culturally tailored interventions addressing affordability, accessibility and SEP disparities are needed to improve dietary behaviours among minority ethnic groups.

This paper explored international experts’ views on what influences the development and implementation of local government (LG) planning policy to support healthy food retail environments; and 2) whether a rapid group model building (RGMB) approach can successfully be applied to capture valuable insights.

Adaptation of methods from community-based system dynamics in the form of RGMB.

In person, facilitated workshop at the World Public Health Nutrition Congress (WPHNC) June 2024, London, England.

WPHNC delegates.

Sixty-six participants contributed to the RGMB. Factors identified that influence the development and implementation of LG planning to support healthy food retail environments centred around community, evidence, policy, political leadership/priorities and capitalism. Feedback loops identified in the causal loop diagram showed the potential influence of policies to support healthy food retail environments on public health outcomes. Research evidence and data were key factors in supporting community demand for healthy food policies and raising the profile of health as a priority, which, in turn, could support funding to support healthy food environments. Political will and corporate influence in the system were shown to be highly influential.

International experts identified that data is urgently needed to support demand for healthy food policies and political will to address key nutrition issues. The influence of corporate interests was viewed as highly influential over the current system across the world. RGMB workshop activities and processes described in this paper can be used successfully to capture expert insights into complex problems using interactive technologies.

With the re-emerging homelessness issue in Hong Kong, given its least affordable housing, securing food to meet the basic physiological needs is of priority concern for the homeless. This study aims to examine the situation and determinants of food insecurity among the homeless in Hong Kong.

Cross-sectional survey on food insecurity level, socio-demographic characteristics, homeless experiences and health status and behaviours.

360 community hot spots of homeless people identified by NGO and experienced social workers in different districts of Hong Kong in 2021.

711 individuals experiencing homelessness.

The observed prevalence of low, medium and high food insecurity levels was 37·4 %, 20·4 % and 42·2 %, respectively. Results from multivariable ordinal logistic regression showed that older, female, non-Chinese and non-married respondents were inversely associated with food insecurity, whereas having sufficient savings for more proper housing was the primary determinant among socio-economic indicators. In addition to reasons for homelessness, risk factors of food insecurity included living in guesthouses/hotels and difficulties due to government measures on homeless control. Except for disability, both self-rated physical and mental health statuses showed dose–response relationships with food insecurity level.

The substantial individual variations in socio-demographic statuses, homeless experiences and health deficits shaped the differential risks of food insecurity within the homeless community in Hong Kong. Targeted homeless programmes should go beyond the conventionally vulnerable groups but consider the multifaceted nature of homeless experiences in relation to food access and integrate health assessments to holistically support the homeless.

To assess the nutritional quality of foods and beverages (F&B) advertised to adolescents and analyse marketing techniques and persuasive appeals used by celebrities and influencers on Instagram.

A content analysis study was conducted using the WHO’s CLICK Monitoring Framework and Nutrient Profile Model.

Instagram, a popular social media platform among adolescents with frequent F&B advertisements by celebrities and influencers.

The top forty-eight Instagram accounts of celebrities and influencers posting F&B advertisements were selected based on follower count and engagement metrics. Nutrient profiling of advertised F&B (n 344) and content analysis of posts featuring F&B (n 326) between January 2021 and May 2023 were performed. Data collected included characteristics of celebrities and influencers, marketing techniques, online engagement and persuasive appeals in the posts.

Carbonated beverages and flavored waters (28·5 %), energy drinks (20·6 %) and ready-made foods (15·4 %) were most frequently advertised, with the majority (89·2 %) of products not permitted for advertisement to adolescents, according to WHO. Common marketing techniques included tagging brand (96·9 %) and using brand logo (94·2 %). The most frequently used persuasive appeals were taste (20·9 %), energy (10·7 %), link to sports events (10·7 %), new product (9·5 %) and fun (7·4 %).

Most F&B advertised on Instagram by celebrities and influencers are prohibited from being advertised to adolescents by the WHO. This highlights the need for stricter regulation of user-generated content and for users and parents to be better educated about persuasive techniques used on social media to make them less vulnerable to the influence of marketing.

To explore the development of the Nutrition Society of Australia’s (NSA) mentoring program for Registered Nutritionists and evaluate the experience of the nutrition professionals participating in the mentoring program.

Case study evaluation utilising a focus group, individual semi-structured interviews, open-ended survey responses and document analysis, via an interpretivist lens.

Australia

Three members of the NSA’s inaugural Mentoring Program Committee participated in a focus group. Eleven program mentees and ten mentors from three consecutive cohorts of the NSA mentoring program for Registered Nutritionists (paired in 2021–2022) agreed to participate.

Data were analysed from survey responses, document analysis, in addition to focus group and in-depth interviews with twelve program participants. Mentoring was seen as a pathway beyond tertiary training to negotiate challenges associated with career development; mentors were seen as facilitators of growth through ‘real world’ skill-set acquisition. Successful partnerships were facilitated by program flexibility and the perception of professional compatibility. Participation in the NSA’s mentoring program was perceived to value-add to society membership, strengthening the society and professional practice, promoting networking within the nutrition community and public health field.

Mentoring programs may provide access to diverse skillsets required in a non-vocational profession, promoting greater confidence and a stronger professional identity. These skills are essential for fostering a resilient nutrition workforce that can help combat the burden of non-communicable disease.

To estimate the potential health benefits from the reduction in consumption of salt and sugar following the introduction of a proposed tax on salt and sugar in the United Kingdom (UK).

Epidemiological modelling study. Life table modelling was used to estimate the expected population health benefits from the reduction in consumption of salt and sugar for four scenarios, each reflecting different manufacturer and consumer responses the proposed tax. Relative risks for twenty-four disease–risk pairs were applied, exploring different pathways between salt and sugar consumption, and mortality and morbidity.

UK.

Population of the UK.

The results show that life expectancy in the UK could be increased by 1·7 (0·3–3·6) to 4·9 (1·0–9·4) months, depending on the degree of industry and consumer response to the tax. The tax could also lead to up to nearly 2 (0·4–3·6) million fewer cases of preventable chronic diseases and an increase of as much as 3·5 (0·8–6·4) million years of life gained. The largest health benefits would accrue from reduced mortality and morbidity from CVD.

Significant benefits to population health could be expected from extending the current tax on sugar-sweetened beverages to other sugary foods and from adding a tax on foods high in salt. The proposed dietary changes are likely to be insufficient to reach national public health targets; hence, additional measures to reduce the burden of chronic disease in the UK will be equally critical to consider.

To examine how the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) online food benefit ordering could influence WIC benefit redemptions.

A cross-sectional study. We compare the average redemption rates between online ordering early adopters and non-adopters among WIC customers before and after implementing WIC online ordering. A propensity score-weighted difference-in-difference model was used to estimate the coefficients.

The Oklahoma WIC programme and a grocery store chain in Oklahoma.

12743 Oklahoma WIC households that had redeemed their food benefits at the grocery store chain in 2020.

WIC online ordering significantly positively affected redemption rates for eight of the fifteen food categories. For example, the difference-in-difference coefficients (P–values) of these food categories were cheese or tofu (0·077, <0·01), yogurt (0·092, <0·01), whole milk (0·082, 0·022), low-fat milk (0·060, <0·01), eggs (0·049, 0·033), breakfast cereal (0·085, <0·01) and infant formula (0·073, 0·039). Two food categories with significantly negative difference-in-difference coefficients had relatively lower redemption rates overall: canned fish (Coefficient = –0·209, P < 0·01) and infant cereal (Coefficient = –0·138, P = 0·015). There were no significant changes in the redemption of fruits and vegetables (Coefficient = 0·031, P = 0·121).

Adopting WIC online ordering was positively associated with benefit redemption rates among most food benefit categories. Our findings provide preliminary but important evidence regarding online food benefit redemption among low-income consumers.

This study outlines the development of a codesigned, coproduced intervention to address the high risk of diet-related non-communicable diseases (NCD) among South Asians (SA) in New Zealand. The objectives were to identify: (1) reasons, concerns and perceptions influencing dietary changes post-migration; (2) preferred formats and delivery modes for the intervention; (3) intervention design features; (4) community volunteers for coproduction; and (5) coproduce the intervention components.

Participatory Action Research.

SA communities in Auckland and Dunedin, New Zealand.

SA immigrants aged 25–59 years. Ten telephone or face-to-face interviews were conducted between 2018 and 2019. Following this, one codesign workshop (n 12) was conducted with the target population and community stakeholders in 2019.

Thematic analysis revealed factors such as children’s preference for boxed cereals and limited time for traditional breakfasts contributed to poor dietary habits. Concerns included meal timing and long-term weight gain, while perceptions such as all home-cooked food is healthy, influenced a lack of concern for long-term health. Preferred formats were educational comics and video clips, with digital platforms as the delivery mode. The workshop helped choose comic characters and identify community members to coproduce video content. The final intervention included eleven comics, eight videos, twelve audio clips and eighteen scientific snippets, organised into five dietary and one physical activity module.

A participatory approach proved feasible for codesigning a culturally tailored lifestyle intervention to address diet-NCD risks in the SA diaspora in New Zealand.

This study aimed to investigate the association between moderate thinness (MT) and muscle strength among children aged 5–7 years old in Ethiopia.

A school-based comparative cross-sectional study was conducted between June and July 2022. Their nutritional status (MT v. well-nourished (WN) was identified using BMI-for-age-and-sex; hand grip was measured using a digital grip strength dynamometer, and biceps, quadriceps and gastrocnemius strength were measured with Digital (Handheld) Dynamometry. Independent predictors of muscle strength were identified using a multivariable linear regression model.

The study was conducted in Kindergarten and primary schools of Jimma Town, located in Southwest Ethiopia.

Children 5–7 years old (n 388) with moderate thinness (MT = 194) and well-nourished peers (WN = 194).

Children with MT (n 198) had significantly lower grip strength, biceps, quadriceps and gastrocnemius muscle groups than WN children (n 198) (P < 0·001). The mean and sd of grip strength were 4·15 (sd 2·56) kg for MT and 5·6 (sd 2·04) kg for WN children. Biceps strength was 34·3 (sd 7·34) Newton (N) for MT and 48 (11·69) N for WN children. Gastrocnemius strength was 30·1 (6·9) N for MT and 45·1 (sd 9·7) N for WN children. After adjusting for background characteristics, WN children had 1·38 times higher grip strength (β = 1·38, P < 0·001), 11·22 times higher biceps strength (β = 11·22, P < 0·001), 16·70 times higher quadriceps strength (β = 16·70, P < 0·001) and 12·75 times higher gastrocnemius strength (β = 12·75, P < 0·001) than MT children.

Children with MT had significantly lower muscle strength than their WN counterparts. This highlights the negative functional effect of wasting.

To examine the impacts of school-based CalFresh Healthy Living (CFHL-California’s SNAP-Ed) interventions post-COVID-19-related school closures and whether student and school characteristics modified intervention impacts on student diet and physical activity (PA).

Quasi-experimental, two-group, pre-post, self-report.

CFHL-eligible public schools (nintervention = 51; ncomparison = 18).

4th/5th grade students (nintervention = 2115; ncomparison = 1102).

CFHL interventions were associated with an increase in consumption frequency of fruit (0·19 times/d (P = 0·015)) and vegetables (0·35 times/d (P = 0·006)). Differences in baseline diet and PA behaviours were observed by student race and gender and by whether the proportion of free and reduced-price meal (FRPM)-eligible students was above the state average. Notably, students in schools with FRPM above the state average reported more frequent consumption of sugar-sweetened beverages (Mean (se): 3·18 (0·10) v. 2·58 (0·11); P = 0·001) and fewer days/week with 60+ min of moderate-to-vigorous PA (MVPA) (Mean (se): 2·8 (0·10) v. 3·21 (0·12); P = 0·020) than those at schools with FRPM at/below the state average. Student gender, school urbanicity and school FRPM modified the relationship between the interventions and certain dietary and/or PA outcomes. Interventions were associated with greater increases in vegetable consumption in more urban schools (β (95 % CI) = 0·67 (0·15, 1·20)), and greater increases in fruit consumption (β (95 % CI) = 0·37 (0·07, 0·66)) and in MVPA in higher FRPM schools (β (95 % CI) = 0·86 (0·33, 1·39)).

Findings reaffirmed effectiveness of school-based CFHL interventions. We identified existing student and school-level disparities and then observed that interventions were associated with greater increases in MVPA in the highest FRPM schools. Findings can inform an equity-centred approach to delivery of school-based interventions that facilitate equal opportunity for all children to achieve lifelong health.

Little is known about food insecurity in Asian Americans (AA). We examined age/ethnic subgroup differences in food insecurity among AA in California.

We examined associations between food insecurity and socio-demographic characteristics among AA (Chinese, Filipino, Korean, and Vietnamese) using the χ2 test. Rolling averages were calculated to examine food insecurity trends.

California.

We used data from the California Health Interview Survey (2011–2018) for AA categorised by age (18–39, 40–59 and 60+ years).

Food insecurity prevalence varied by subgroup, with the highest observed in older adult (aged 60+ years) Vietnamese (26 %). Between 2011–2014 and 2015–2018, food insecurity prevalence increased 20–45 % across older adults, but showed a decreasing trend among younger adults. Being foreign born and speaking a language other than English at home were associated with increased food insecurity.

Community-engaged research to develop culturally appropriate strategies for mitigating food insecurity among older AA is warranted.
