The World Health Organization recommends countries adopt policies that encourage the creation of healthier food retail. In Australia, some organisations have created enforceable regulation for healthier food retail in settings under their contractual control. While progressive for public health, little evidence exists on the characteristics of individuals and organisations influencing sustainment of such initiatives. We explored the perspectives of those involved in a sustained (six year) real-world healthy vending initiative in a university setting in Melbourne, Australia. Qualitative interviews were undertaken with seven of the eight individuals involved in the initiative and informed by the Consolidated Framework for Implementation Research and the regulatory concept of social licence. Reflexive thematic analysis was used to generate themes on individual and organisational factors associated with sustainment. Two individual-level themes included participants enjoyment and skills for 'getting the job done' and working on innovative projects. Individual self-efficacy and enjoyment from working on innovative projects, combined with interviewees' perception that their organisation had a role in leading social change, contributed to the initiative's sustainment. Two organisation-level themes included the University leading innovation and having a responsibility to serve the needs of its community within the constraints of the need for 'financial viability' and the provision of 'consumer choice'. This study brings to the fore evidence on the individual and organisational characteristics that contribute to the sustainment of a healthy food vending initiative from the perspective of those involved in implementation. Exploration of the importance of these characteristics to other food retail settings is required.

South Asians are among the fastest-growing immigrant population group in the United States (U.S.) with a unique disease risk profile. Due in part to immigration and acculturation factors, South Asians engage differently with behavioural risk factors (e.g. smoking, alcohol intake, physical activity, sedentary behaviour, and diet) for hypertension, which may be modified for the primary prevention of cardiovascular disease. Using data from the Mediators of Atherosclerosis in South Asians Living in America cohort, we conducted a cross-sectional analysis to evaluate the association between behavioural risk factors for cardiovascular disease and diet. We created a behavioural risk factor score based on smoking status, alcohol consumption, physical activity, and TV watching. We also calculated a Dietary Approaches to Stop Hypertension (DASH) dietary score based on inclusion of relevant dietary components. We used both scores to examine the association between engaging with risk factors for hypertension and the DASH diet among a cohort of South Asian adults. We found that participants with 3-4 behavioural risk factors had a DASH diet score that was 3 units lower than those with no behavioural risk factors (aβ: -3.25; 95% CI: -4.28, -2.21) and were 86% less likely to have a DASH diet score in the highest category compared to the lowest DASH diet score category (aOR: 0.14; 95% CI: 0.05, 0.37) in the fully adjusted models. These findings highlight the relationship between behavioural risk factors for hypertension among South Asians in the U.S.

Metabolic syndrome (MetS) is a widespread and complex health disorder. Dietary habits and consumption of simple sugars have been shown to play an important role in the prevention and treatment of MetS. This cross-sectional study was conducted in a population of 3380 adults from the Shiraz University of Medical Sciences (SUMS) employees' health cohort. The healthy beverage index (HBI) and healthy beverage score (HBS) were calculated. Risk for MetS and its components, including blood pressure, fasting blood glucose, waist circumference, triglyceride levels, and high-density lipoprotein cholesterol, were measured using standardised protocols. Results showed a significant inverse association between higher adherence to HBI (OR = 0.60, 95% CI: 0.48-0.74, P < 0.001) and HBS (OR = 0.80, 95% CI: 0.65-0.97, P = 0.030) with lower risk of MetS. Also, we observed a significant association between higher level of HBI and HBS with decreased risk of hypertension, as a critical component of MetS. These findings support the notion that healthier beverage consumption, as indicated by higher HBI and HBS levels, may play a critical role in reducing the risk of MetS.

The study aims to identify family child care home (FCCH) setting- and environment-level predictors related to providers' perceived difficulty in implementing the Child and Adult Care Food Program (CACFP) recommendations for serving vegetables to children. This was a cross-sectional study, which used a validated paper-based survey with a multi-method data analysis approach. Participants were licenced FCCH providers (N = 943) in Nebraska, who were predominantly White (94%), non-Hispanic (97%), CACFP-participants (89%), and in urban areas (64%). Reflective latent variable modelling was conducted in Mplus to explore associations between dependent variable and predictors. Dependent variable was providers' perceived difficulty to implement CACFP recommendations for serving vegetables. Predictors were providers' mealtime practices, perceived barriers to serve healthy foods, CACFP participation, geographic location, food access, food insecurity, and child poverty. Qualitative comments (n=122) from the survey were analysed using direct content analysis approach. Providers' perceived lack of time to prepare foods and perceived children's taste preferences increased their perceived difficulty; and CACFP-participation decreased their perceived difficulty to implement CACFP recommendations for serving vegetables. Qualitative comments highlighted that providers felt discouraged to serve vegetables knowing that vegetables would likely be wasted because of children's preferences. More tailored professional development is required to address FCCH providers' perceived difficulty and build providers' skills on preparing time saving, CACFP-reimbursable and appealing vegetable recipes, and on strategies to promote vegetable consumption in children.

Animal source foods (ASF) are nutrient-dense and essential for the growth and development of children. The Bangladesh Demographic and Health Survey (BDHS) 2022 reported that approximately two-thirds of children aged 6-23 months consumed eggs/flesh foods. However, overall consumption patterns, trends, and factors influencing ASF intake among children in Bangladesh were not well-documented. Therefore, the study aimed to assess the trends and associated factors of ASF consumption among children aged 6-23 months in Bangladesh. A total of 9401 children were extracted from four consecutive BDHS (2011, 2014, 2017/18, and 2022). The Cochran-Armitage test was conducted to assess the trends in ASF consumption, while a two-stage multilevel mixed-effects logistic regression was performed to identify the associated factors. The consumption of ASF significantly increased to 79.1% in 2017/18 from 67% in 2011 but decreased to 73.3% in 2022. ASF consumption was found to be higher among children whose mothers were educated (AOR = 1.60, 95% CI = 1.30-1.98), employed in either agricultural (AOR = 1.27, 95% CI = 1.04-1.54) or non-agricultural (AOR = 1.36, 95% CI = 1.07-1.72) activities, pregnant (AOR = 2.54, 95% CI = 1.66-3.87), had received ANC 1-3 times (AOR = 1.43, 95% CI = 1.20-1.72) or ≥4 times (AOR = 1.59, 95% CI = 1.29-1.95), and was exposed to media (AOR = 1.21, 95% CI = 1.04-1.39). Furthermore, consumption increased with increasing the age of children, and the wealth of their families. However, children who experienced illness were less likely to consume ASF (AOR = 0.76, 95% CI = 0.68-0.86). The recent declines in ASF consumption emphasize the need for targeted interventions to increase ASF consumption among children in Bangladesh.

Participant recruitment and retention are consistently recognised as significant, costly challenges in nutrition intervention trials. Decentralised study procedures address some of the recruitment and retention limitations in traditional trial methodology. Understanding participant perceptions and experiences of decentralised methods in nutrition studies is key to improving trial design and conduct. The aim of this study was to explore participant opinions about remote delivery of a dietary supplement intervention trial. Adults enrolled in a clinical trial of a milk fat globule membrane nutritional supplement for improvement of psychological wellbeing were invited to take part in a post-intervention interview. Interviews were conducted over video conferencing and transcribed. Using a semi-structured interview format six aspects of trial design were discussed: general processes, written instructions, contact throughout the study, self-collection of saliva samples, wearable device use, and cognitive assessment. Thematic analysis derived themes from the data for each of the aspects of trial conduct discussed. Seventy-three participants completed the interview. Interviewees reported a positive overall experience of the remote delivery procedures used. Accessible communication between researchers and participants and clear written instructions were identified as key to participant experience. Recall of instructions and adherence to the nutritional intervention was difficult for some respondents with suggestions made for facilitating this in future remote delivery nutrition studies. Use of wearables, in-home saliva sampling, and self-administered cognitive assessments were feasible and acceptable to most participants. The remote delivery of a nutritional intervention trial, including self-collected biological samples, is feasible and positively viewed by participants.

India's nutrition transition has led to an increased burden of overweight/obesity (body mass index of ≥23 kg/m²), driven by lifestyle factors like poor diet, inactivity, and substance use, prompting public health interventions. However, these interventions lack supporting evidence, especially in rural areas, hindering effective strategies for this population. To address this evidence gap, this study used cohort data (baseline: 2018-19, follow-up: 2022-23) from the Birbhum Population Project (West Bengal, India) to analyse lifestyle risk factors and their association with incidence and remission of overweight/obesity among adults aged ≥18 years (sample: 8,974). Modified Poisson regression model was employed to attain the study objective. From 2017-2018 to 2022-2023, the prevalence of overweight/obesity increased from 15.2% (95% CI: 14.1%-16.4%) to 21.0% (95% CI: 19.7%-22.3%) among men and from 24.1% (95% CI: 22.9%-25.2%) to 33.8% (95% CI: 32.5%-35.1%) among women. Overall, 23.0% (95% CI: 21.8%-24.3%) of adults experienced incidence of overweight/obesity, while 13.9% (95% CI: 12.4%-15.6%) experienced remission. Use of motor vehicles among unemployed participants was associated with incident overweight/obesity (relative risk or RR: 1.058; 95% CI: 1.023-1.095; P: 0.001). Vigorous activity at home (including gardening, yard work, and household chores) was linked to higher odds of recovering from overweight/obesity (RR: 1.065; 95% CI: 1.008-1.125; P: 0.025). Frequent tobacco use (often/daily vs. none) was inversely associated with remission of overweight-obesity (RR: 0.689; 95% CI: 0.484-0.980; P: 0.038), as was each 1 ml in alcohol consumption (RR: 0.995; 95% CI: 0.991-0.999; P: 0.022). Discouraging habitual motor vehicle use may help prevent overweight/obesity, while promoting home-based activities may aid remission, particularly for women who are at higher risk for overweight/obesity.

Psychosocial stimulation is one of the recommended interventions in the management of hospitalised children with severe acute malnutrition (SAM). However, there is currently limited scientific evidence supporting the effectiveness of the intervention. The study aimed to examine the effects of psychosocial stimulation on the development, nutrition, and treatment outcomes of hospitalised SAM children. A cluster-randomised controlled trial was conducted among health facilities that provide inpatient care for children with SAM in Silti Zone, Ethiopia. Fifty-eight children enrolled in the intervention facilities were provided stimulation intervention during their inpatient care and for 6 months after discharge. Sixty-eight children enrolled from control health facilities received routine inpatient care without stimulation and were followed for six months. Health education was provided to all caregivers on child health-related topics. Child development and nutrition outcomes were assessed four times using Denver II-Jimma and anthropometric measurements while the length of hospitalisation was used to measure treatment outcome. Children in the intervention group showed significantly better scores in Personal Social (p=0.001, effect size=0.77), Fine Motor (p=0.001, effect size=1.87), and Gross Motor (p=0.001, effect size=0.78) developmental domains from baseline to end line. Language domain however showed a significant difference only after discharge and intervention children scored better at six months (p<0.001, effect size=0.59). The intervention significantly improved treatment outcomes (p=0.010), but no significant changes in nutritional outcomes were documented. The findings highlighted the benefits of the intervention and the need to promote these interventions in health facilities within resource-limited settings.

The vitamin K (VK) levels vary greatly among different populations and in different regions. Currently, there is a lack of reference intervals for VK levels in healthy individuals, The aim of this study is to establish and validate the reference intervals of serum vitamin K1 (VK1) and vitamin K2 (VK2, specifically including menaquinone-4 (MK4) and menaquinone-7 (MK7)) levels in some healthy populations in Beijing. Serum VK1, MK4, and MK7 were firstly measured by high-performance liquid chromatography and mass spectrometry in 434 subjects. The reference intervals for three indicators were established by calculating the data of 2.5 and 97.5 percentiles. Finally, preliminary clinical validation was conducted on 60 apparent healthy individuals undergoing physical examination. In the young, middle-aged, and elderly groups, the reference intervals of VK1 were 0.180 ng/mL ∼ 1.494 ng/mL, 0.247 ng/mL ∼ 1.446 ng/mL, and 0.167 ng/mL ∼ 1.445 ng/mL, respectively. The reference intervals of MK4 were 0.009 ng/mL ∼ 0.115 ng/mL, 0.002 ng/mL ∼ 0.103 ng/mL, and 0.003 ng/mL ∼ 0.106 ng/mL, respectively. The reference intervals of MK7 were 0.169 ng/mL ∼ 0.881 ng/mL, 0.238 ng/mL ∼ 0.936 ng/mL, and 0.213 ng/mL ∼ 1.012 ng/mL, respectively. The reference intervals had been validated by the samples of healthy individuals for physical examination. In conclusion, the reference intervals of VK established in this study with different age groups have certain clinical applicability, providing data support for further multicentre studies.

The ripening-dependent changes in antioxidant activities and phytochemical content of mango (Mangifera indica L.) cultivar Safaid Chonsa at various ripening stages were evaluated. The ripening time period was divided into five stages (RSI-RSV) and the pulp was subjected to proximate analysis, antioxidant potential, and UHPLC/MS-based non-targeted metabolite fingerprinting. Proximate analyses depicted variations in moisture, dry matter, fat, protein, carbohydrate, and energy parameters. Maximum DPPH activity (51%) was observed at stages III, IV, and V while FRSP increased 31% at RS V as compared to stage I. Total antioxidant capacity and total reducing power potential were maximum (295.7 and 345.71 µg AAE/mg extract, respectively at stage V. Total phenolic content increased from 3.57 µg GAE/mg extract to 5.72 µg GAE/mg extract from stage I to RSIII while 19% increase in total flavonoid content was observed at stage V as compared to stage I. UHPLC/MS analysis showed presence of Aconitic acid, methylisocitric acid, 4-O-methyl gallate, beta-glucogallin, xanthenes, sakebiose, Isobergaptene, Fructoselysine 6-phosphate, Citbismine C, and many others at different ripening stages of chonsa mango extracts. The results conclude that during the mango ripening stages, changes in phytochemical composition have positive correlation with antioxidantive potential. These phytochemicals have nutritional and nutraceutical effects on human health therefore ripening stage should be considered for consumption of mango.
