Primary school aged children (aged 4-12 years) in Australia consume approximately 40% of daily energy from energy-dense, nutrient poor foods and fewer than 5% meet the recommended guidelines for vegetables and fruit (ABS 2018). Poor eating habits in children can track into adulthood increasing the risk of non-communicable diseases later in life (Nicklaus 2013). Children spend a large amount of time at school where they are provided with social contexts which influence behaviour development (FAO, 2022) and thus are ideal settings for teaching children about food and nutrition (FAO, 2022; WHO 2017). This pilot study was designed in response to a call to action from a local primary school in southeast Melbourne facing disadvantage. Anecdotally, the school reported poor food literacy with many students bringing unhealthy lunches. The school asked us to design, pilot, and evaluate a student education program enabling healthier lunches among these children. The aim of the study was to explore the effectiveness of a 4-week food and nutrition education program delivered to grade 4 students within a disadvantaged area targeting, children’s food-related knowledge, behaviours and self-efficacy (confidence) to pack a healthy lunch. The program delivered weekly 1-hour interactive sessions over four weeks (October-November 2022). Topics included healthy eating, designing healthy lunches and food safety and were delivered using interactive games, activities, quizzes and food tasting. Students completed an online survey measuring their knowledge, self-efficacy and behaviour (e.g. foods packed in their lunchbox) pre- and post- program. A comparative analysis of the pre- and post-survey responses was performed using McNemar Tests in SPSS version 29.0. Sixty students completed both the pre- and post-surveys. A significant increase (p<0.001) in knowledge of recommended daily serves of fruit (pre 43%, post 80%) and vegetables (pre 17%, post 54%) was observed. There was also a significant (p<0.001) increase in student’s ability to identify ‘sometimes food’. No changes were observed in identification of ‘everyday food’, sources of protein and sources of dairy food or safety knowledge. Children’s confidence to make healthy food swaps significantly increased from pre- to post- program (27%45%, p = 0.035). We observed significant increases in children’s food and nutrition related knowledge for some topics and confidence to make healthy food swaps following completion of the program. A program of longer duration may be beneficial to observe additional improvements in knowledge as well as behaviour change, including foods packed in school lunches.

TikTok is a global social media platform popular with young people, encouraging viewers to engage with user-generated video content (through likes, shares and comments) and mimic displayed behaviours (by creating similar videos or content). It is therefore a powerful and engaging tool that has potential for the widespread dissemination of information (or misinformation) and to influence behaviours. Social media is saturated with the promotion of ‘diet culture’ and has a strong influence on the eating behaviours of young people (1,2). This is concerning as childhood and adolescence are critical periods of growth requiring optimal nutrition (3). This study aimed to investigate how dieting is portrayed on TikTok and consider the potential implications for public health. A cross-sectional descriptive content analysis was undertaken of 50 videos from each of the five most popular diet-related hashtags (#diet, #whatieatinaday, #wieiad, #dietitian, #diettips). A codebook was developed to analyse the body-related content referenced (weight measurement, calories, body image, body checking, body comparisons over time) and collect the engagement for each video (likes, comments and shares). Overall, the 250 videos contributed to a total of 197.2 million likes (M = 789,051.0, SD = 923,335.0), 126,7251 comments (M = 5,069.0, SD = 9,315.3), and 3.8 million shares (M = 15,423.2, SD = 41,271.3). Most videos featured adults (n = 205, 82%), and only a small number of videos featured identifiable children or adolescents (n = 16, 6.4%). The information and advice regarding diets and eating behaviours came from two types of sources: 'experts’ and regular creators sharing their personal experience. Almost half of the videos were educational or instructional (n = 116, 46.4%), of which 74 (63.8%) were posted by users who claimed expert status. The most common titles by those claiming to be experts were “dietitian” (n = 43, 58.1%), “health and wellness coach” (n = 7, 9.5%), “doctor” (MD; n = 6, 8.1%), “fitness trainer” (n = 6, 8.1%), and “nutritionist” (n = 3, 4.1%). Of the videos that specifically mentioned a certain diet, the most common diets were low calorie (n = 32, 12.8%), vegan (n = 14, 5.6%), self-reported healthy eating (n = 12, 4.8%), and fasting (n = 10, 4.0%). The use of humour was the only feature significantly associated with engagement. Health professionals are presented with a unique opportunity to widely and positively influence the public by utilising the popularity of TikTok amongst young people to disseminate evidence-based information and promote healthy eating behaviours. Our findings suggest that experts using authentic, humorous, and engaging personas would be more likely to be popular on this platform.

National surveys in India, through measures of anthropometry and biomarkers, have identified a triple burden of malnutrition (undernutrition, micronutrient deficiencies and overnutrition) in adolescents(1). However, there is a dearth of high-quality data on individual dietary behaviour of this population(2) and the importance of sub-national dietary surveys in filling this gap has been identified(3). The objective of this study was to assess the intake of energy (E) and macronutrients and the contribution of macronutrients to E in a random sample of 11–13-year-old schoolchildren in Delhi, India. Method: The study was approved by The University of Adelaide Human Research Ethics Committee and the Independent Ethics Committee of the Centre for Chronic Disease Control, New Delhi. The target sample size of 360 was based on a ± 5% margin of error in estimated sugars intakes. Using the list of private schools in Delhi (n = 1374), a statistician external to the research team generated a random sample of 150 schools stratified by districts (n = 11). Using this list, schools were invited to participate, and recruitment continued until 10 schools consented. Teachers shared study information with parents; interested parents filled in the online consent form. Assent was obtained from schoolchildren. Participants recorded all food and drink consumed over three consecutive days, including one weekend day, in a food diary. Information recorded was entered into an online dietary assessment tool, Intake24 Southeast Asia version, during an interview with each participant. The Intake24 database of over 2400 food photographs of more than 100 foods was used to ascertain portion size. The Intake24 database converts food and drink reported into the intake of nutrients through integrated food compositional tables. Of 514 pupils providing consent, 393 participants (76.4%) (169 girls, 224 boys) completed the study. The median daily E intake was 10.8 (IQR 9.0 −12.5) MJ for girls, and 12.3 (IQR 10.3- 15.2) MJ for boys. For the 97 girls and 144 boys providing body weight data, Physical Activity Level ratios were 2.0 and 2.1 respectively. The median daily intakes for girls were: protein 64.6 (IQR 54.8-79.3) g; carbohydrate 336.5 (IQR 285.3- 393.6) g; and saturated fat 45.6 (IQR 34.8-58.3) g. The respective values in boys were: protein 74.4 (IQR 61.4; 89.4) g; carbohydrate 379.6 (IQR 317.8; 461.8) g; and saturated fat 54.6 (IQR 41.9-69.5) g. There were no significant between-gender differences in percent E from protein (10.2 (IQR 9.2; 11.4)), or carbohydrate (52.4 (IQR 48.7; 56.7)). Girls obtained less E from saturated fat (16.1 (IQR 11.0-18.2) compared with boys 16.3 (IQR 14.2 - 19.1) (P<0.05). In conclusion, in this sample of adolescents from private schools in Delhi, E intake was above FAO recommended levels and median total fat intake exceeded the recommended threshold of 35%(4).

Published: May 2024

Consumption of 300 mg of a New Zealand berry extract containing 105 mg anthocyanins for 7 days has been shown to increase running distance during repeated sprints to exhaustion(1). The supplemented group also displayed higher blood lactate concentration over the first thirty minutes of recovery time(1). However, there is limited research available on the acute effects of berry-derived anthocyanins on sports performance. We aimed to evaluate the effect of a single dose of 12 g of a New Zealand berry anthocyanin-enriched powder (NZBP) supplement containing 120 mg of anthocyanins on sprint performance in a randomised controlled crossover trial using the modified Loughborough Intermittent Shuttle Test (m-LIST). The m-LIST protocol consisted of 6 x 15-min blocks divided into four blocks of “prescribed-pace” activity (blocks 1 - 4) (participants exercise based on audible signals) followed by two blocks of “self-paced” (blocks 5, 6) running (no audible signals) with a 3-min rest period between each block. Each block consisted of repeated sequences of 3x20 m walks at 5.4 km/h, 1x15 m sprint, 3x20 m run and 3x20 m jog. Fourteen recreationally active males (mean ± SD age: 29.53 ± 9.35 years, height: 170.84 ± 24.13 cm, weight: 76.24 ± 8.26 kg, V˙O2max: 46.64 ± 4.40 mL∙kg-1∙min-1) participated in three indoor sessions. The first session focused on a multistage fitness test (beep test) to determine V˙O2max and the run and jog prescribed speeds for blocks 1 to 4. For the main trial visits (minimum 7-day wash-out period in between), participants consumed a body weight adjusted standardised dinner (lasagna, garlic bread, banana, and salad greens) and arrived at the laboratory fasted the next morning (between 6-7:30 am). They then consumed the study supplement (NZBP supplement or placebo mixed with 100 ml water) along with the standardised breakfast (100 g yogurt, 50 g granola, and 30 ml milk). One hour after breakfast the participants undertook a 10-min standardised warm-up, followed by the m-LIST protocol. No significant differences (two-way repeated measures ANOVA; p = 0.286) were found in average sprint speed from blocks 1 to 6 within or between NZBP and placebo groups. No effect of supplementation and no interaction effect was observed for sprint distance, sprint time, heart rate, reaction time, movement, or blood lactate concentration. The observed changes induced by repeated sprints on ratings of feeling scale, felt arousal scale, and perceived exertion (p = <0.001, all) were also not affected by supplementation (p = 0.679, p = 0.288, p = 0.327 respectively). Thus, an acute dose of NZBP containing 120 mg anthocyanins under the conditions reported here did not improve repeated sprint performance in recreationally active males.

Published: May 2024

The prevalence of food allergies in New Zealand infants is unknown; however, it is thought to be similar to Australia, where the prevalence is over 10% of 1-year-olds(1). Current New Zealand recommendations for reducing the risk of food allergies are to: offer all infants major food allergens (age appropriate texture) at the start of complementary feeding (around 6 months); ensure major allergens are given to all infants before 1 year; once a major allergen is tolerated, maintain tolerance by regularly (approximately twice a week) offering the allergen food; and continue breastfeeding while introducing complementary foods(2). To our knowledge, there is no research investigating whether parents follow these recommendations. Therefore, this study aimed to explore parental offering of major food allergens to infants during complementary feeding and parental-reported food allergies. The cross-sectional study included 625 parent-infant dyads from the multi-centred (Auckland and Dunedin) First Foods New Zealand study. Infants were 7-10 months of age and participants were recruited in 2020-2022. This secondary analysis included the use of a study questionnaire and 24-hour diet recall data. The questionnaire included determining whether the infant was currently breastfed, whether major food allergens were offered to the infant, whether parents intended to avoid any foods during the first year of life, whether the infant had any known food allergies, and if so, how they were diagnosed. For assessing consumers of major food allergens, 24-hour diet recall data was used (2 days per infant). The questionnaire was used to determine that all major food allergens were offered to 17% of infants aged 9-10 months. On the diet recall days, dairy (94.4%) and wheat (91.2%) were the most common major food allergens consumed. Breastfed infants (n = 414) were more likely to consume sesame than non-breastfed infants (n = 211) (48.8% vs 33.7%, p≤0.001). Overall, 12.6% of infants had a parental-reported food allergy, with egg allergy being the most common (45.6% of the parents who reported a food allergy). A symptomatic response after exposure was the most common diagnostic tool. In conclusion, only 17% of infants were offered all major food allergens by 9-10 months of age. More guidance may be required to ensure current recommendations are followed and that all major food allergens are introduced by 1 year of age. These results provide critical insight into parents’ current practices, which is essential in determining whether more targeted advice regarding allergy prevention and diagnosis is required.
A qualitative exploration of food choice motives of Pacific Islanders: Implications for the use of the Food Choice Questionnaire in understudied populations
Authors: Buksh S.M.
Published: May 2024

Nutrition transitions are key contributors to the obesity epidemic plaguing South Pacific Island countries (SPIC). Prior to European contact and colonisation, traditional Pacifica diets consisted mainly of root crops, indigenous fruits and vegetables, freshwater proteins and seafood(1). This diet has been replaced by diets high in processed foods which are high in salt, sugar and unhealthy fats(2). Various political, economic, environmental and socio-cultural factors have been associated with the proliferation of unhealthy foods in Pacifica diets. However, very few studies have examined how these changes have impacted individual food choices. This study aims to address the gap in the knowledge of food choice motives of Pacific Islanders. An online qualitative survey was used(1) to explore how the nine food choice motives in the widely used Food Choice Questionnaire (FCQ)(3) impact food choice and (2) to identify additional food choice motives, not captured in the FCQ. The first section of the survey included open-ended questions which explored the top three food choice motives of the participants. This section was followed by a series of open-ended questions exploring participant’s views on the nine food choice motives from the FCQ. The last part of the survey asked participants to identify any other food choice motives which were not already identified in the survey. An exploratory qualitative approach, employing inductive and deductive thematic analyses, was used to analyse results(4). The sample (N = 105) was predominantly female (73%), living with family (72%) and the average age was 22.06 years (S.D = 5.0). It consisted of 28% indigenous Fijians, 26% Fijians of Indian descent, 15% Solomon Islanders, 13% I-Kiribati and smaller percentages of students from Niue (3%), Samoa (5%), Tonga (5%) and Vanuatu (5%). Of the nine FCQ motives, the most commonly identified top three food choice motives included price (n = 54), health (n = 45), and sensory appeal, especially taste (n = 40). Participants also identified three new food choice motives which many ranked in their top three motives: satiety concerns (n = 22), food quality and hygiene when eating out (n = 26) and religious or cultural food restrictions (n = 11). Additionally, issues with face validity of the health, convenience, price, weight control and familiarity food choice motives from the FCQ were identified. These findings highlight the importance of validity studies prior to using FCQ, and more broadly other similar instruments, with understudied populations like that of SPIC. The findings also provided important insights into the food choice motives of Pacific Islanders and can inform public health interventions for encouraging healthy eating. Further research using an adapted FCQ with larger and diverse samples will increase its effectiveness of measuring food choice motives in the region.
A comparison of nutritional contents and price differential between dairy and plant-based milk in Fijian supermarkets
Authors: Kumar S. , Chand A.
Published: May 2024

Plant-based milk import has been increasing in the Fijis supermarkets. While this milk may cater for vegans(1) and people with allergies from dairy milk, the question always remains that if the plant-based milk are equally nutritious and available at reasonable price in comparison to the dairy milk. Dairy milk is commonly consumed by the Fijian population while the plant-based milk is positioning itself into the market as alternatives. Therefore, this paper is aimed at comparing the nutrient content and price of milk from dairy cows and plant milk sources available in the supermarkets in Fiji. This study examines different brands of dairy and plant-based milk in 6 major supermarket chains in the central part of Fiji. There was 22 dairy milk, 6 soya milk, 5 almond milk and 4 oat milk sampled from these supermarkets. The median value of milk nutrient composition and price for dairy milks and different plant-based milks were calculated as the data was not normally distributed. The Kruskal- Wallis test was conducted to further analyse the difference between the nutrient composition and price of dairy milks and plant-based milk. The energy composition in the dairy milk was significantly higher (p < 0.01) when compared with plant-based milks soya almond milk and oat. There was a significant difference (p < 0.01) in dairy milk protein, fat and saturated fat when compared to plant-based milks. The result indicated that the protein, fat, and saturated fat are both significantly higher in cow’s milk. Milk carbohydrate analysis indicate higher composition in dairy milk therefore a significant difference (p < 0.01) was noted when compared to almond milk(except soya and oat milk). There is a significant difference (p < 0.01) in sugar indicating cow’s milk having higher sugar when compared to plant-based milk (except soya milk The sodium composition in the dairy milk and all the plant- based milk showed no significance difference (p > 0.05) in the composition. There was also significant difference (p < 0.05) in comparison of calcium composition of dairy milk and plant-based milk indicating almond milk with lower calcium. The phosphorus composition in dairy milk and plant-based milk indicates that there is a strong significant difference (p < 0.01) (except soya and oat milk). The riboflavin composition was significantly higher (p < 0.01) in dairy milk compared to soya and oat milk. Lastly, there was significant difference (p < 0.01) between price of dairy milk when compared to plant-based milk. The study concludes that there is more nutrient in dairy milk and the price is significantly lower than plant-based milk at which these nutrients are available in dairy milk.
A nutritional modelling framework for inclusion in a Norwegian food system model
Authors: Lozano R. , Smith N.W. , McNabb W.
Published: May 2024

The aim of this study was to apply a comprehensive mathematical model designed to assess the current and future availability of food, as well as the resulting nutrient availability and intake, in the context of the Norwegian population. The model explores various scenarios, including self-sufficiency levels for food supply and impacts on nutrition recommendations. A food mass balance charting production, import, export, feed, seed, and consumer allocation in the Norwegian food system provided insights into the nutrients available to the population. The analysis included a comparison with two versions of the Nordic Nutrient Recommendations (NNR)1, with the latest version recommending substantial changes in food consumption compared to current dietary patterns in Norway. The nutrient analysis compared the food mass to Matvaretabellen2 and was supplemented with data from the United Nations World Population Prospects3 and the Food and Agriculture Organisation/World Health Organisation/United Nations4 report to ensure comprehensive nutrient analysis. Micronutrient gaps were observed in Iodine (94% of the target intake) and Vitamin D (46% of the target intake), while saturated-fatty acids slightly exceeded the recommended requirements (107% of the upper limit) based on the current baseline scenario. The updated NNR4 recommends changes to specific food categories, namely fruits, vegetables, nuts, and seeds. A secondary scenario testing compared against the updated NNR found that increasing the availability of the supply of these groups does not result in any new nutrient gaps, demonstrating the feasibility of addressing the issue on a national supply basis. These approach offers a mathematical-modelling based tool that can be used to provide information for a national food system. Leveraging the model’s capacity to simulate various scenarios, informed decisions to optimise self-sufficiency levels and align food supply with recommended nutritional guidelines can be made. To improve the model, higher data resolution and clearer categorisation of food groups are required which can then be linked into a more complete national food system. The mathematical model presented in this study provides a framework for understanding of food and nutrient availability in Norway. By identifying critical nutrient gaps and potential solutions, this research contributes knowledge for a healthier and sustainable food future for the nation.
An e-Delphi study to evaluate content validity of the Teacher Food and Nutrition-Questionnaire

Published: May 2024

Teacher food and nutrition (FN) related factors include diet quality, health perceptions and FN attitudes. These factors are associated with both personal health and wellbeing, and teacher classroom FN practices. With Australian schoolteachers currently experiencing high levels of stress, anxiety and burnout, measuring and understanding the status of teacher FN-related health and wellbeing is needed. However, first there needs to be a comprehensive and validated tool to collect these data. This study aims to evaluate content validity of a new tool, the Teacher Food and Nutrition Questionnaire (TFNQ), to measure FN-related health and wellbeing of Australian schoolteachers. The TFNQ was developed following an extensive literature review of FN data collection methods previously used in schoolteacher populations internationally. It initially included 16 FN-related constructs alongside six constructs of wellbeing and mental health, and seven lifestyle covariates identified from the literature review. A two-round e-Delphi methodology was implemented using a mix of structured, rank-order and qualitative questions administered to an international, multidisciplinary group of experts via an online survey1. Descriptive statistics were used to derive a consensus vote (set at 75%) of constructs and covariates to be prioritised for inclusion. Qualitative feedback was analysed to identify areas of potential change. Twenty-three experts participated in round-one from Australia (n = 15), Switzerland (n = 3), The United Kingdom (n = 2), Canada (n = 1), The United States of America (n = 1) and New Zealand (n = 1). Of the 29 constructs and covariates evaluated in round-one of the e-Delphi, all achieved above 75% consensus, yet qualitative feedback indicated potential to reduce and streamline the number of constructs. Rank order questions and qualitative feedback resulted in the removal of four FN and two wellbeing constructs along with four lifestyle covariates. Round-two included 19 (83%) experts from round-one, with 83% (n = 15) in agreement regarding question order. Final feedback indicated only minor adjustments to question item phrasing. The e-Delphi process modified the TNFQ and established content validity. Further construct validity and reliability testing is required to produce a robust tool for measuring FN-related health and wellbeing of contemporary Australian schoolteachers.
Drivers of change: dietary change, food and nutrition security and agricultural practices in peripheral communities in Pacific Island countries and territories: A scoping review protocol
Authors: Harding A. , Burkart S. , Nunn P. , Svensen S.
Published: May 2024

Pacific Island Countries and Territories (PICTs) are experiencing a Diet-Related Non-Communicable Disease (DR-NCD) health crisis(1). Increasing rates of DR-NCDs such as Type 2 diabetes and cardiovascular disease have been linked to dietary transitions and increasing food insecurity in the region(2). Anthropogenic climate change has also been identified as a significant threat to food security in PICTs(3). Additionally, the impacts of the COVID-19 Pandemic have been identified as both a contributor to food insecurity in the region and as an opportunity to transform PICT food systems and reduce rates of DR-NCDs(4). Yet, the drivers of dietary change, food security and agricultural practices in peripheral PICT communities are not well documented or understood. To determine how these drivers may change in the future and the impacts this may have on Pacific peoples, a deeper understanding of the historical and contemporary drivers of change is necessary. The aim of this scoping review was to collate existing information to improve this understanding, by mapping key factors evident in the literature that underpin the links between DR-NCDs and food security with a focus on women in PICT peripheral communities, to better clarify the challenges, working definitions and conceptual boundaries in the research area. The review maps where research has been conducted geographically and how the links between DR-NCDs and food security in PICTs have been investigated over time and identifies projections and suggestions for the future. The scoping review was conducted in accordance with a pre-defined protocol available online(5). A total of 476 peer-reviewed sources and 126 grey literature sources were identified by the initial search criteria. Two independent researchers completed title/abstract and full text screening using Covidence, and data extraction using a data extraction tool. The resulting data was quantified in table format, with common themes and ideas presented qualitatively. Sources spanned all sectors of PICT food systems with a heavy focus on production from fisheries and agriculture. Most PICTs were represented in the findings. Many drivers of change within food systems were identified, some of which included the impacts of anthropogenic climate change, the COVID-19 pandemic, and urbanisation. The drivers impacted all four pillars of food security, and many were directly or indirectly related to dietary and lifestyle changes associated with DR-NCD risk factors. This data is accompanied by an interpretation of results and a narrative summary. These results provide a useful platform to further explore the drivers of dietary change, food security, agricultural practices and DR-NCD’s in this region.
Fiber intake is inversely associated with the prevalence of circadian syndrome among adults attending NHANES 2005-2016
Authors: Shi Z. , Bassil M. , Liu J.
Published: May 2024

It is well-known that many modern lifestyles, including the use of artificial light, shift work, irregular or short sleep, sedentary activity, and unhealthy diet can disrupt the circadian rhythm. This disruption can result in the so-called Circadian Syndrome (CircS) which has been identified as a risk factor for a variety of chronic diseases. The concept of Circadian Syndrome (CircS) was first proposed by Zimmet et al in 2019. CircS has been shown to be a better predictor for cardiovascular diseases (CVD) than the metabolic syndrome (MetS) in adults in China and USA 1,2. Dietary patterns are found to be associated with CircS 3, whereby western dietary pattern was positively related, while prudent pattern was inversely associated, with CircS in the US adults. However, no prior study has investigated the association between fiber intake and CircS. We, thus, aimed to fill this research gap. We analysed data from 10,486 adults aged 20 years and above years who attended the 2005-2016 National Health and Nutrition Examination Survey (NHANES). Fiber and other nutrients intake were assessed using two days 24 hours recall. CircS was derived from all five components of MetS (i.e. central obesity, elevated fasting glucose, elevated triglyceride, reduced HDL-Cholesterol and elevated blood pressure), in addition to short sleep (sleep duration <6 hours/day) and depressive symptoms (PHQ-9 score ≥5). A cut-off for CircS was set as ≥ 4 components. Multivariable logistic regression was used to assess the association between fiber intake and CircS. Mean age of participants was 50.3(SD 17.6) years, and 41.3% had CircS. The mean (SD) fiber intake was 7.8 (2.1), 12.9 (1.3), 17.9 (1.7), and 28.9 (8.2) g/day across the quartiles of fiber intake. The prevalence of CircS decreased across quartiles of fiber intake (44.5% in Q4 and 37.1% in Q1). In the multivariable logistic model adjusting for age, gender, ethnicity, energy intake, education and lifestyle factors, across the quartiles of fiber intake, the odds ratios (ORs) (95%CI) for CircS were: 1.00, 0.91 (0.76-1.08), 0.82 (0.70-0.96), 0.79 (0.63-0.98) (p trend 0.012), respectively. No significant interactions were found between fiber intake and race, gender, smoking, alcohol drinking, and physical activity, in relation to CircS. In conclusion, a high fiber intake was associated with a lower prevalence of CircS among US adults. The findings highlight the importance of fiber intake for the prevention of metabolic and circadian syndrome, suggesting a potentially accessible and cost-effective lifestyle approach to improve public health. Our results underscore the concern that most of the US adults had fiber intake below the recommended level. Longitudinal studies are needed to validate the findings in different populations.
Investigating nutritional status and body composition in children with cerebral palsy; the Eat, Sleep Play-CP study
Authors: Copeland M. , Diaz-Rodriguez R. , Hill N.S. , Lithander F.E. , Williams S.A.
Published: May 2024

Cerebral palsy (CP), or to use the Te Reo term “Hōkai Nukurangi”, is an umbrella name for a group of permanent neurodevelopmental disorders, affecting movement and posture(1), and is the most common childhood onset physical disability globally. The available literature on the nutritional status of children with CP describes high rates of malnutrition, however data appears to be skewed towards children of higher levels of impairment impacting functional independence. Less is known about the nutritional status of children with lower levels of impairment. The aim of the “Eat, Sleep, Play-CP” study was to evaluate total energy intake, total protein intake and the timing of protein intake in relation to physical activity for children with CP across all functional levels living in Aotearoa New Zealand. Children with CP aged 5-12 years were invited to participate in an observational assessment of dietary intake using parent reported 24-hour dietary recall (Intake 24) on three non-consecutive days, accompanied by a questionnaire capturing self-reported sleep and physical activity patterns. Body composition was assessed via whole body dual energy X-ray absorptiometry scan. Nine participants (6 males, median age: 10 years, n = 2 Māori), across Gross Motor Function Classification System levels I-IV, and Eating and Drinking Classification System levels I-III took part in the study. The median total energy intake was 7267kJ/d (range 5355-10731.96kJ/d), and median protein intake was 67g/d (range 49-111g/d). According to the Nutrient Reference Values for Australia and New Zealand (NRV)(2), 3 of the 9 participants (33%) were within the recommended range for energy intake according to their age and reported physical activity levels. Of the other 6, 4 were below and 2 were above the recommended ranges. All 9 met the recommended protein intake (NRV). Participants had a median percentage body fat of 40% (range 20-46%), and non-fat mass of 58% (range 52-76%). Five participants fell within the overweight or obese range for their age and sex, three of whom were within the recommended range of total energy daily intake according to NRVs. This outcome may indicate that for some children with CP, recommendations could be over-estimating the actual requirements. These early results may bring in to question current practice around guidance for energy intake requirements for children with CP and their whānau to support healthy body composition. Further investigations are needed to establish whether specific energy intake guidelines are required for children with CP.
The Plural Planet: A Democratic Culture of Earthlings
Authors: Hyvönen Ari-Elmeri
Published: May 2024

We are entering the age of planetary politics defined by consciousness of human impact on the Earth System, and the planetary ecosystem's responses to our activities. This poses a major challenge to democratic theory. How do we protect life without evoking a planetary sovereign? This article argues that the planetary condition requires imaginatively expanding existing democratic concepts to make room for new connections, realities, and beginnings. It demonstrates this by focusing on Hannah Arendt's notion of plurality as the law of the earth. Read through the Roman lex, which emerges from the conflict between the plebs and the patricians, this notion helps us imagine a planetary politics premised on the creation of new relationships between previously discrete entities. Building on this interpretation, I discuss scientific expertise and indigenous perspectives as modes of cultivating political imagination to expand our understanding of the democratic stage beyond the human species.

Published: May 2024

This paper proposes a virtual reality-based dual-mode teleoperation architecture to assist human operators in remotely operating robotic manipulation systems in a safe and flexible way. The architecture, implemented via a finite state machine, enables the operator to switch between two operational modes: the Approach mode, where the operator indirectly controls the robotic system by specifying its target configuration via the immersive virtual reality (VR) interface, and the Telemanip mode, where the operator directly controls the robot end-effector motion via input devices. The two independent control modes have been tested along the task of reaching a glass on a table by a sample population of 18 participants. Two working groups have been considered to distinguish users with previous experience with VR technologies from the novices. The results of the user study presented in this work show the potential of the proposed architecture in terms of usability, both physical and mental workload, and user satisfaction. Finally, a statistical analysis showed no significant differences along these three metrics between the two considered groups demonstrating ease of use of the proposed architecture by both people with and with no previous experience in VR.

Partner symptom accommodation in generalized anxiety disorder: a preliminary examination of correlates with symptoms and cognitive behavioural therapy outcome
Authors: Malivoire B.L. , Rowa K. , Milosevic I. , McCabe R.E.
Published: May 2024

Background:

Symptom accommodation is suggested to maintain anxiety pathology and interfere with treatment effectiveness for anxiety and related disorders. However, little is known about symptom accommodation in generalized anxiety disorder (GAD).

Aim:

This study investigated the associations between romantic partner symptom accommodation, GAD symptoms, intolerance of uncertainty (IU), relationship satisfaction, and cognitive behavioural therapy (CBT) outcomes from the perspective of the person with GAD.

Method:

One hundred and twelve people with GAD participated in group CBT and completed measures at pre- and post-treatment.

Results:

All participants endorsed that their partner engaged in symptom accommodation to some extent, and the most commonly endorsed type was providing reassurance. Greater self-reported partner symptom accommodation was associated with greater GAD symptoms, chronic worry severity, IU, and relationship satisfaction at baseline. Partner symptom accommodation was found to significantly decrease over treatment; however, less improvement in symptom accommodation from pre- to post-treatment was associated with worse treatment outcomes.

Discussion:

This study is the first to show that partner symptom accommodation is prevalent in adults with GAD and to elucidate the presentation and frequency of behaviours. The findings provide preliminary evidence that targeting partner symptom accommodation in treatment may improve CBT outcomes.
Utopia in New York: Nicola Chiaromonte and the New York Intellectuals’ “Superstition of Science”
Authors: Swain Amanda
Published: May 2024

This article reintroduces Italian antifascist intellectual Nicola Chiaromonte to anglophone twentieth-century intellectual history by foregrounding Chiaromonte's transatlantic exchange with the New York intellectuals. Drawing from Chiaromonte's unpublished notes and correspondence, as well as his published writing in English and Italian, it elaborates how what I call Chiaromonte's “negative utopianism” migrated concepts and concerns from the political-philosophical context of 1930s Paris to 1940s New York. Though descriptions of Chiaromonte in New York accentuate his rejection of Marxism within sectarian radical circles, I resituate this tension vis-à-vis the philosophical clash between Chiaromonte's speculative, phenomenological conceptual framework and his US milieu's scientific rationalism and naturalistic pragmatism. Thanks to his influence on Dwight Macdonald's politics magazine, Chiaromonte became a contact point with the ideals animating the antifascist resistance and the theoretical transformations inaugurated by the decentered subject—one whose promotion of relationality and limit as grounds for recentering the transatlantic left had longer echoes.
Law, Colonial-Capitalist Floods, and the Production of Injustices in Eastern India: Insights for Climate Adaptation
Authors: Ohdedar Birsha
Published: May 2024

Floods are not merely ‘natural’ disasters; rather, they emerge as socio-natural phenomena shaped by political, social, and economic processes. Law plays a pivotal role in producing and sustaining these processes and contributes to the creation of unjust environments. Drawing on political ecology and environmental history, this article analyzes the role of law and its interactions with colonialism and capitalism in the Damodar river valley in Eastern India. The Damodar river valley is an intensely engineered and hazardous region, a site of multiple interventions and developmental and ecological experiments for over a century. Colonial and post-colonial legacies have left a lasting imprint on legal, policy, and institutional frameworks, establishing a path-dependent trajectory for addressing future climate change adaptation challenges. While focusing on a specific case study, the article's approach and findings have broader significance, especially in the context of climate adaptation. The central argument underscores the need to understand the political and legal dimensions of flooding, and reinforces the need for a shift beyond incremental adjustments that do not tackle the underlying structures that produce the injustices associated with floods. It highlights the importance of ‘transformative adaptation’ approaches that address the root causes of climate-related disasters, such as restructuring power relations between actors, reconfiguring governance structures, and scrutinizing ideologies that mediate how water is used and distributed.
A Giant Impact Origin for the First Subduction on Earth
Authors: Yuan Qian , Gurnis Michael , Asimow Paul D. , Li Yida
Published: May 2024

Hadean zircons provide a potential record of Earth's earliest subduction 4.3 billion years ago. It remains enigmatic how subduction could be initiated so soon after the presumably Moon‐forming giant impact (MGI). Earlier studies found an increase in Earth's core‐mantle boundary (CMB) temperature due to the accumulation of the impactor's core, and our recent work shows Earth's lower mantle remains largely solid, with some of the impactor's mantle potentially surviving as the large low‐shear velocity provinces (LLSVPs). Here, we show that a hot post‐impact CMB drives the initiation of strong mantle plumes that can induce subduction initiation ∼200 Myr after the MGI. 2D and 3D thermomechanical computations show that a high CMB temperature is the primary factor triggering early subduction, with enrichment of heat‐producing elements in LLSVPs as another potential factor. The models link the earliest subduction to the MGI with implications for understanding the diverse tectonic regimes of rocky planets.
2‐D Geodynamic Modeling of the Central South Atlantic Wide Rifted Margins, Implications for Evaporite Deposition
Authors: Theunissen T. , Huismans R. S. , Rouby D. , Gout C.
Published: May 2024

The thick late syn‐ to early post‐rift shallow water evaporites in the most distal part of wide rifted margins is paradoxical with the deep depression at crustal breakup time predicted by isostatically compensated lithospheric thinning. Elevation of the distal margin and water depth during deposition of the late syn‐rift evaporites in the central South Atlantic are not well constrained and remain to be quantified. We use forward 2‐D thermo‐mechanical modeling coupled with melt prediction and surface processes to assess the contribution of lithospheric and mantle processes on the distal margin topography and subsidence history during continental rifting. Models show that (a) counter‐flow of depleted lower lithospheric mantle during rifting explains the magma‐poor nature of these margins and (b) weak crust and syn‐rift sediment control the wide crustal necking and subsidence history of the distal margin. Integration of our modeling results with quantified geophysical and geological observations suggests that (a) base level was down to −600 m below present‐day global sea level (bsl) during distal margin formation in the Aptian before sag and evaporite deposition, (b) base level was about −300/−400 m bsl at the end of evaporite deposition, and (c) scenarios with a fixed shallow base level (−400 m bsl) or with an increasing base level from an initially deep position (−1,600 m bsl) during evaporite deposition can both fit the observed evaporite distribution. However, erosional features along the base of evaporites suggest a deep initial base level.

Flooding is one of the most dangerous and costly natural hazards, and has a large impact on infrastructure, mobility, public health, and safety. Despite the disruptive impacts of flooding and predictions of increased flooding due to climate change, municipalities have little quantitative data available on the occurrence, frequency, or extent of urban floods. To address this, we have been designing, building, and deploying low‐cost, ultrasonic sensors to systematically collect data on the presence, depth, and duration of street‐level floods in New York City (NYC), through a project called FloodNet. FloodNet is a partnership between academic researchers and NYC municipal agencies, working in consultation with residents and community organizations. FloodNet sensors are designed to be compact, rugged, low‐cost, and deployed in a manner that is independent of existing power and network infrastructure. These requirements were implemented to allow deployment of a hyperlocal, city‐wide sensor network, given that urban floods often occur in a distributed manner due to local variations in land development, population density, sewer design, and topology. Thus far, 87 FloodNet sensors have been installed across the five boroughs of NYC. These sensors have recorded flood events caused by high tides, stormwater runoff, storm surge, and extreme precipitation events, illustrating the feasibility of collecting data that can be used by multiple stakeholders for flood resiliency planning and emergency response.
