Dietary Changes of Youth during the COVID-19 Pandemic: A Systematic Review.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has taken the lives of millions and disrupted countless more worldwide. Simply living through the pandemic has had drastic effects on the health of citizens. Diet, an important aspect of health, has been uniquely affected by the pandemic, although these changes have not been sufficiently studied among youth. OBJECTIVES: The objective of this systematic review was to investigate dietary changes of youth during COVID-19. METHODS: A prespecified literature review was conducted using MEDLINE, EMBASE, Scopus, and CINAHL to identify studies from January 2020 to May 2023 that assessed dietary changes among youth aged ≤20 y compared with before the pandemic. Only quantitative observational studies that were published in English were included. Two authors completed all screening/study selection independently, with disagreements being resolved via discussion. Data extraction was completed by 1 author. Dietary changes were categorized into food groups and habits for analysis purposes. RESULTS: In total, 67 studies met inclusion criteria. Most studies used recall to assess changes (48/67; 71.6%). Most studies found an increase in fruits and vegetables (24/46; 52.2%), grain products (6/11; 54.5%), meat, poultry, and eggs (4/8, 50.0%), diet quality indices and/or overall dietary assessments (7/13, 53.8%), and the frequency of snacking (9/12; 75.0%), whereas generally finding a decrease in ultraprocessed foods (32/53; 60.4%), compared with before the COVID-19 pandemic. Mixed findings or primarily no changes were found for fish and aquatic products, legumes, beans, seeds and nuts, milk and milk products, breakfast consumption, and nutrient intake. CONCLUSIONS: Mostly favorable dietary changes appear to have occurred among youth during COVID-19, although there were several mixed findings and unclear takeaways among the foods and habits under study. The heterogeneity of defining food groups was a noted limitation in the current review.

Impact of COVID-19-related restricted family presence policies on Canadian pediatric intensive care unit clinicians: a qualitative study.

PURPOSE: Pediatric intensive care units (PICUs) worldwide restricted family presence in response to the COVID-19 pandemic. We aimed to explore the experiences and impact of restricted family presence policies on Canadian PICU clinicians. METHODS: We conducted a qualitative study that followed an interpretive phenomenological design. Participants were PICU clinicians providing direct patient care in Canada during periods of COVID-19-related restricted family presence. We purposively sampled for maximum variation among survey participants who consented to be contacted for further research on the same topic. In-depth interviews were conducted remotely via telephone or video-call, audio-recorded, and transcribed. Interviews were inductively coded and underwent thematic analysis. Proposed themes were member-checked by interviewees. RESULTS: Sixteen PICU clinicians completed interviews. Interviewees practiced across Canada, represented a range of disciplines (eight nurses, two physicians, two respiratory therapists, two child life specialists, two social workers) and years in profession (0-34 years). We identified four themes representing the most meaningful aspects of restricted family presence for participants: 1) balancing infection control and family presence; 2) feeling disempowered by hospital and policy-making hierarchies; 3) empathizing with family trauma; and 4) navigating threats to the therapeutic relationship. CONCLUSION: Pediatric intensive care unit clinicians were impacted by restricted family presence policies during the COVID-19 pandemic. These policies contributed to feelings of disempowerment and challenged clinicians' perceived ability to provide the best family-centred care possible. Frontline expertise should be incorporated into the design and implementation of policies to best support family-centred care in any context and minimize risks of moral distress for PICU clinicians.

RéSUMé: OBJECTIF: Les unités de soins intensifs pédiatriques (USIP) du monde entier ont restreint la présence des familles en réponse à la la pandémie de COVID-19. Notre objectif était d'explorer les expériences et l'impact des politiques de restriction de la présence familiale sur les clinicien·nes des USIP canadiennes. MéTHODE: Nous avons mené une étude qualitative qui a suivi un plan phénoménologique interprétatif. Les participant·es étaient des clinicien·nes des USIP qui dispensaient des soins directs aux patient·es au Canada pendant les périodes de présence restreinte des familles en raison de la COVID-19. Nous avons délibérément échantillonné pour obtenir une variation maximale parmi les participant·es à l'enquête qui ont accepté d'être contacté·es pour d'autres recherches sur le même sujet. Des entretiens approfondis ont été menés à distance par téléphone ou par appel vidéo, enregistrés et transcrits. Les entretiens ont été codés de manière inductive et ont fait l'objet d'une analyse thématique. Les thèmes proposés ont été contrôlés par membre par les personnes interrogées. RéSULTATS: Seize cliniciennes et cliniciens des USIP ont passé des entrevues. Les personnes interrogées exerçaient partout au Canada, représentaient un éventail de disciplines (huit infirmiers et infirmières, deux médecins, deux inhalothérapeutes, deux spécialistes du milieu de l'enfant, deux travailleuses et travailleurs sociaux) et d'années d'expérience professionnelle (de 0 à 34 ans). Nous avons identifié quatre thèmes représentant les aspects les plus significatifs de la présence restreinte de la famille pour les participant·es : 1) l'équilibre entre la prévention des infections et la présence de la famille; 2) le sentiment d'être dépossédé·e par les hiérarchies de l'hôpital et de ne pas pouvoir participer à l'élaboration des politiques; 3) le sentiment d'empathie à l'égard des traumatismes familiaux; et 4) la réponse aux menaces qui ont pesé sur la relation thérapeutique. CONCLUSION: Les cliniciens et cliniciennes des unités de soins intensifs pédiatriques ont été touché·es par les politiques de restriction de la présence familiale pendant la pandémie de COVID-19. Ces politiques ont contribué à un sentiment d'impuissance et ont remis en question la capacité perçue des équipes à fournir les meilleurs soins possibles axés sur la famille. L'expertise de première ligne devrait être intégrée à la conception et à la mise en œuvre des politiques afin de mieux soutenir les soins axés sur la famille dans n'importe quel contexte et de minimiser les risques de détresse morale pour les cliniciennes et cliniciens des USIP.

Developing community-based physical activity interventions and recreational programming for children in rural and smaller urban centres: a qualitative exploration of service provider and parent experiences.

BACKGROUND: Children's physical inactivity is a persisting international public health concern. While there is a large body of literature examining physical activity interventions for children, the unique physical activity context of low-density communities in rural areas and smaller urban centres remains largely underexplored. With an influx of families migrating to rural communities and small towns, evaluations of health promotion efforts that support physical activity are needed to ensure they are meeting the needs of the growing populations in these settings. The aim of this community-based research was to explore service providers' and parents' perspectives on physical activity opportunities available in their community and recommendations toward the development and implementation of efficacious physical activity programming for children in rural communities and smaller urban centres. METHODS: Three in-person community forums with recreation service providers (n = 37 participants) and 1 online community forum with the parents of school-aged children (n = 9 participants) were hosted. An online survey and Mentimeter activity were conducted prior to the community forums to gather participants' views on the barriers and facilitators to physical activities and suggestions for activity-promoting programs. The service provider and parent discussions were audio-recorded, transcribed verbatim, and analyzed following a deductive approach guided by Hseih and Shannon's (2005) procedure for direct content analysis. A code list developed from the responses to the pre-forum survey and Mentimeter activity was used to guide the analysis and category development. RESULTS: Seven distinct categories related to the existing physical activity opportunities and recommendations for programs in rural communities and smaller urban centres were identified during the analysis: (1) Recovery from Pandemic-Related Measures, (2) Knowledge and Access to Programs, (3) Availability, (4) Personnel Support, (5) Quality of Programs and Facilities, (6) Expenses and Subsidies, and (7) Inclusivity and Preferences. CONCLUSION: To improve the health and well-being of children who reside in low-density areas, the results of this study highlight service provider and parent recommendations when developing and implementing community-based physical activity programs and interventions in rural and smaller urban settings, including skill development programs, non-competitive activity options, maximizing existing spaces for activities, and financial support.

Does Dietitian Involvement During Pregnancy Improve Birth Outcomes? A Systematic Review.

Maternal diet during pregnancy can have a significant impact on maternal and offspring health. As nutrition counselling is an important component of prenatal care, registered dietitians (RDs) are uniquely trained professionals who can provide personalized nutrition counselling customized to an individual's sociocultural needs. The objective of this systematic review was to determine if RD involvement during pregnancy is associated with a lower prevalence of adverse birth outcomes in the United States and Canada. The review was conducted through a search of four databases: PubMed, CINAHL, Embase, and Web of Science. A total of 14 studies were identified. Women had a lower prevalence of low birth weight and preterm infants when RDs were involved during prenatal care. While RD involvement during pregnancy was not associated with macrosomia, more research is needed to assess its relationship with small for gestational age, large for gestational age, and infant mortality. Future research should also investigate the specific dietary advice provided by RDs and the extent and timing of their involvement throughout pregnancy to better understand the mechanisms surrounding nutrition counselling, in utero development, and health outcomes.

Maternal Eating Disorders and Adverse Birth Outcomes: A Systematic Review and Meta-Analysis.

Previous systematic reviews have reported on the relationship between eating disorders (EDs) and birth outcomes, but there are no existing meta-analyses on this topic. This systematic review and meta-analysis examines the association between lifetime maternal EDs, including anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) with low birth weight (LBW), preterm birth (PTB), small for gestational age (SGA), large for gestational age (LGA), and miscarriage. Four databases were systematically searched for quantitative literature on maternal EDs that preceded birth outcomes. Eighteen studies met the inclusion criteria and were included in the review. The meta-analyses included 6 studies on miscarriage, 11 on PTB, 4 on LBW, 9 on SGA, and 4 on LGA. The Mantel-Haenszel random effects model was used to test the associations between EDs and birth outcomes. The results showed significant positive associations between AN and LBW (OR 1.74, 95% confidence interval (CI) 1.49, 2.03), AN and SGA (OR 1.39, 95% CI 1.17, 1.65), BN and PTB (OR 1.19, 95% CI 1.04, 1.36), and BED and LGA (OR 1.43 95% CI 1.18, 1.72). EDs were not significantly correlated with miscarriage. These findings reveal the importance of screening for and treating EDs in pregnant women.

A survey of pediatric intensive care unit clinician experience with restricted family presence during COVID-19.

PURPOSE: Limiting family presence runs counter to the family-centred values of Canadian pediatric intensive care units (PICUs). This study explores how implementing and enforcing COVID-19-related restricted family presence (RFP) policies impacted PICU clinicians nationally. METHODS: We conducted a cross-sectional, online, self-administered survey of Canadian PICU clinicians to assess experience and opinions of restrictions, moral distress (Moral Distress Thermometer, range 0-10), and mental health impacts (Impact of Event Scale [IES], range 0-75 and attributable stress [five-point Likert scale]). For analysis, we used descriptive statistics, multivariate regression modelling, and a general inductive approach for free text. RESULTS: Representing 17/19 Canadian PICUs, 368 of 388 respondents (94%) experienced RFP policies and were predominantly female (333/368, 91%), English speaking (338/368, 92%), and nurses (240/368, 65%). The mean (standard deviation [SD]) reported moral distress score was 4.5 (2.4) and was associated with perceived differential impact on families. The mean (SD) total IES score was 29.7 (10.5), suggesting moderate traumatic stress with 56% (176/317) reporting increased/significantly increased stress from restrictions related to separating families, denying access, and concern for family impacts. Incongruence between RFP policies/practices and PICU values was perceived by 66% of respondents (217/330). Most respondents (235/330, 71%) felt their opinions were not valued when implementing policies. Though respondents perceived that restrictions were implemented for the benefit of clinicians (252/332, 76%) and to protect families (236/315, 75%), 57% (188/332) disagreed that their RFP experience was mainly positive. CONCLUSION: Pediatric intensive care unit-based RFP rules, largely designed and implemented without bedside clinician input, caused increased psychological burden for clinicians, characterized as moderate moral distress and trauma triggered by perceived impacts on families.

RéSUMé: OBJECTIF: Limiter la présence de la famille va à l'encontre des valeurs centrées sur la famille des unités de soins intensifs pédiatriques (USIP) canadiennes. Cette étude explore comment la mise en œuvre et l'application des politiques de restriction de la présence familiale liées à la COVID-19 ont eu une incidence sur les cliniciennes et cliniciens des USIP à l'échelle nationale. MéTHODE: Nous avons mené un sondage transversal, en ligne et auto-administré auprès des cliniciens et cliniciennes des USIP canadiennes afin d'évaluer leur expérience et opinions sur les restrictions, la détresse morale (thermomètre de détresse morale, intervalle de 0 à 10) et les impacts sur la santé mentale (échelle d'impact des événements [EIE], intervalle de 0 à 75, et le stress qui peut y être attribué [échelle de Likert à cinq points]). Pour l'analyse, nous avons utilisé des statistiques descriptives, une modélisation de régression multivariée et une analyse inductive générale pour le texte libre. RéSULTATS: Représentant 17/19 USIP canadiennes, 368 des 388 personnes répondantes (94 %) ont vécu des politiques de restriction de la présence familiale et étaient principalement des femmes (333/368, 91 %), anglophones (338/368, 92 %) et infirmières (240/368, 65 %). Le score moyen (écart type [ET]) rapporté de détresse morale était de 4,5 (2,4) et était associé à l'impact différentiel perçu sur les familles. Le score moyen (ET) total de l'EIE était de 29,7 (10,5), ce qui suggère un stress traumatique modéré, 56 % (176/317) des personnes répondantes déclarant une augmentation ou une augmentation significative du stress associé aux restrictions liées à la séparation des familles, au refus d'accès et à la préoccupation pour les impacts familiaux. L'incongruité entre les politiques et les pratiques de restriction des visites familiales et les valeurs des USIP était perçue par 66 % des personnes répondantes (217/330). La plupart (235/330, 71 %) estimaient que leurs opinions n'étaient pas prises en compte lors de la mise en œuvre de politiques. Bien que les répondant·es aient perçu que les restrictions avaient été mises en œuvre dans l'intérêt des cliniciens et cliniciennes (252/332, 76 %) et pour protéger les familles (236/315, 75 %), 57 % (188/332) n'étaient pas d'accord pour dire que leur expérience de la restriction des visites familiales était principalement positive. CONCLUSION: Les règles de restriction de la présence familiale dans les unités de soins intensifs pédiatriques, en grande partie conçues et mises en œuvre sans l'avis du personnel clinique au chevet des patient·es, ont entraîné une augmentation du fardeau psychologique pour le personnel clinique, caractérisée par une détresse morale modérée et un traumatisme déclenché par des répercussions perçues sur les familles.

Applicability of the Socioecological Model for Understanding and Reducing Consumption of Ultra-Processed Foods in Canada.

Ultra-processed foods (UPFs) have become a major contributor to the diets of Canadians, with a recent report from Statistics Canada suggesting Canadians are consuming almost one-half of their calories from UPFs. Research has linked UPF consumption with increased risk for chronic diseases such as cardiovascular disease and type 2 diabetes, among others. This paper sought to investigate the popularity of UPFs, particularly among children and teens, utilizing the socioecological model as a framework to illustrate how influences at multiple levels (i.e., public policy, organizational, community, interpersonal, and individual) have played a role in the proliferation of UPFs. Evidence from previous studies is used to identify how factors at different levels may influence UPF consumption and discuss potential strategies for reducing UPF consumption. To meaningfully reduce UPF consumption among Canadians, all levels should be considered, with the goal of creating a healthier Canadian population.

Residential greenness and substance use among youth and young adults: Associations with alcohol, tobacco, and marijuana use.

INTRODUCTION: Research has identified positive associations between green space and physical and mental health outcomes. Substance use outcomes, however, have received considerably less attention. This study investigates the association between residential greenness and substance use through an analysis of alcohol, tobacco, and marijuana use among youth and young adults. METHODS: This study utilized three waves (2016-2018) of the Canadian Community Health Survey (CCHS), as well as residential greenness data from the Canadian Urban Environmental Health Consortium (CANUE). Multinomial logistic regression was used to explore variation in the pattern of substance use between greenness quartiles. The sample included 14,070 youth and young adults (15-25 years). RESULTS: Residential greenness was not associated with alcohol use in general but was associated with lower odds of frequent binge drinking. Residential greenness was also associated with lower odds of tobacco use and greater odds of marijuana use. CONCLUSION: This study provides evidence that residential greenness is associated with patterns of substance use. The strength and direction of association, however, is highly contingent upon the substance under investigation. Living in greener neighborhoods may confer certain benefits to substance use and abuse among youth and young adults.

Parental presence at the bedside of critically ill children in the pediatric intensive care unit: A scoping review.

Parental presence at the bedside (PPB) of critically ill children in the pediatric intensive care unit (PICU) is necessary for operationalizing family-centred care. Previous evidence syntheses emphasize parent-healthcare provider interactions at rounds and resuscitation; our focus is the parent-child dyad. Prior to embarking on further study, we performed a scoping review to determine the breadth and scope of the literature addressing PPB of critically ill children in the PICU. We searched five online databases (MEDLINE, EMBASE, CINAHL, Cochrane Library, and PSYCHINFO) and the grey literature to identify English and French reports from January 1960 to June 2020 addressing physical parental presence with children (birth to 18 years) in intensive care units, without limitation by methodology. Screening, reference selection, and data extraction were performed by two independent reviewers. Data were extracted into a researcher-designed tool. We identified 204 publications (81 quantitative, 68 qualitative, 22 mixed methods, and 9 descriptive case or practice change studies, and a further 24 non-study reports). PPB was directly assessed in 78 (38%) reports, and was the primary objective in 64 (31%). Amount or quality of presence was addressed by 114 reports, barriers and enablers by 152 sources, and impacts and outcomes by 134 sources. While only 6 reports were published in the first two decades of our search (1960-1980), 17 reports were published in 2019 alone. Conclusions: A relatively large body of literature exists addressing PPB of critically ill children. Separate systematic evidence syntheses to assess each element of PPB are warranted. Scoping review protocol registration: Open science framework, protocol nx6v3, registered 9-September-2019. What is Known: • Parental presence at the bedside of critically ill children must be enabled to facilitate family centeredness in care. • Systematic evidence syntheses have focused on parental presence at rounds or resuscitation, rather than with the child throughout the intensive care journey. What is New: • Many reports (n=204) address parental presence at the bedside in the pediatric intensive care unit, though most do as incidental findings • Identifies studies addressing key elements of parental presence in the PICU including barriers and enablers to, amount and quality of, and impact and outcomes of parental presence, and demonstrates trends over time and geography.

A randomized control trial of a Canadian-based school food program on the home food environment.

Research provides evidence of take-home effects in school-based nutrition interventions, citing children as important influencers of family nutrition, acting as agents of change in the household and potentially influencing family food consumption. Therefore, the purpose of this randomized control trial was to examine whether implementation of a centrally procured school food program would produce changes in children's home food environment, including fruit and/or vegetable availability and parental modelling of fruit and/or vegetable consumption. A secondary objective was to investigate whether children's fruit and/or vegetable intake predicted their parent's fruit and/or vegetable intake. A total of 60 schools participated in the evaluation, including 2443 students (and their parents) in grades 5-8. Findings indicated that the intervention did not produce take-home effects on children's home availability of fruit (p = 0.52) and vegetables (p = 0.67) or parental modelling of fruit (p = 0.26) and vegetable consumption (p = 0.78), which may be related to the fact that only food provisions were given. However, children's fruit and vegetable consumption predicted parents' fruit and vegetable consumption (p < 0.001), thereby indicating that children may possess the capacity to influence home nutrition. Future school-based nutrition interventions are recommended to be multi-component (e.g. experiential learning, parent involvement) and that encourage nutrition leadership opportunities for children in the home context.

Within the family, children are important influencers of nutrition and exert their influence both in household food purchases and mealtime decisions. As such, children may use their influence to produce changes in food consumption for all family members. This study evaluated whether providing students with fruit and vegetables at school as part of a government-funded snack program would produce changes in family and household nutrition. Specifically, this study examined if the availability of fruit and vegetables at home could be increased through children requesting the same food served at school, as well as if parents would model the behaviour of eating more fruit and vegetables in front of their children. Results of this study found that providing children with fruit and vegetables at school did not increase the availability of fruit and vegetables at home or encourage parents to eat more fruit and vegetables in front of their children. However, strengthening the argument that children may influence family nutrition, children's fruit and vegetable intakes were shown to influence parents' intakes. These findings suggest that, instead of only providing fruit and vegetables to children, future nutrition initiatives should include additional components, such as hands-on activities and parental engagement.

Identifiable Dietary Patterns of Pregnant Women: A Canadian Sample.

Purpose: To estimate the percentage of a sample of pregnant women in Canada following a vegetarian, vegan, low-carbohydrate, gluten-free, Mediterranean, or well-balanced diet, before and during pregnancy and to explore if pregnant women received and were satisfied with nutrition information received from health care providers (HCPs).Methods: Participants were conveniently sampled through Facebook and Twitter. An online survey collected data on sociodemographic characteristics, maternal diet, and whether women received and were satisfied with nutrition information from their HCPs. The McNemar test assessed changes in the proportion of diets followed before and during pregnancy.Results: Of 226 women, most followed a well-balanced diet before (76.9%) and during (72.9%) pregnancy (p = 0.26). Vegetarian, gluten-free, vegan, and low-carbohydrate diets were the least followed diets before and during pregnancy (vegetarian: 7.6% vs 5.3%; gluten-free: 4.9% vs 4.0%; vegan: 2.7% vs 2.2%; low-carbohydrate:4.0% vs 0.4%). Overall, the number of women following restrictive diets before pregnancy was significantly reduced throughout pregnancy (19.1% vs 12.0%, p < 0.001). Only 52.0% of women received nutrition information from their primary HCP, and 35.6% were satisfied with the nutrition information received.Conclusions: Most women followed a well-balanced diet before and during pregnancy and approximately one-third were satisfied with the information received from HCPs.

Sixty Percent of Foods Advertised in Grocery Store Flyers are Not In-line with Canada's Food Guide.

Purpose: To evaluate foods advertised in discount and premium grocery flyers for their alignment with Canada's 2007 Food Guide (CFG) and assess if alignment differed by food category, season, page location, and price.Methods: Weekly flyers (n = 192) were collected from discount and premium grocery chains from each of 4 seasons. Health Canada's Surveillance Tool was used to assess food items as in-line or not in-line with CFG.Results: Of 35 576 food items, 39.7% were in-line with CFG. There were no differences in proportions of foods not in-line in discount versus premium flyers (60.9% and 60.0%, respectively). Other Foods and Meat & Alternatives were advertised most (28.0% and 26.3%, respectively; P < 0.001). Milk & Alternatives were the least advertised food group (10.3%). Vegetables & Fruit (19.6%), Grains (21.6%), Milk & Alternatives (20.6%), and Meat & Alternatives (20.2%) were promoted least in Fall (P < 0.001). A higher proportion of foods advertised on middle pages were not in-line (61.0%) compared with front (56.6%) and back (58.8%) pages (P < 0.001). Not in-line foods were more expensive ($3.49, IQR = $2.82) than in-line foods ($3.28, IQR = $2.81; P < 0.001).Conclusions: While there was no difference in healthfulness of foods advertised in discount versus premium flyers, grocers advertised more foods not in-line with CFG. Government policies to improve the food environment should consider grocery flyers.

Examining Elementary School Children's Knowledge about Food and Nutrition in Southwestern Ontario, Canada.

Purpose: Knowledge is fundamental to helping children make nutritional choices that support lifelong healthy behaviours. This study (i) investigates elementary school children's knowledge about food and nutrition and (ii) identifies sociodemographic factors influencing children's reported knowledge.Methods: In 2017-2019, a survey was administered to 2443 students (grades 5-8) at 60 schools across southwestern Ontario, Canada, and a parent survey was used to validate self-reported sociodemographics. Multiple regression was used to analyse children's knowledge scores and related sociodemographic factors. A total knowledge score was calculated by summing correct responses derived from 46 individual questions in the student survey.Results: Mean total knowledge score was 29.2 out of a possible 46 points (63.5% correct). Students demonstrated some knowledge and awareness of strategies to encourage fruit and vegetable consumption, healthy food selection, nutrition, and food preparation skills, although knowledge of food guide recommendations and locally sourced produce were limited. Female sex, family income, and rurality were associated with higher knowledge scores.Conclusions: Results provide insight regarding strengths and gaps in elementary-school children's food and nutrition knowledge. Poor performance of students on specific food guide-related questions suggests that the general guidance of the 2019 Canada's Food Guide might be better understood by children and adolescents.

The quantity and composition of household food waste during the COVID-19 pandemic: A direct measurement study in Canada.

The COVID-19 pandemic may have amplified the environmental, social, and economic implications of household food waste. A better understanding of household food wasting during the pandemic is needed to improve the management of waste and develop best practices for municipal waste management programs under crisis circumstances. A waste composition study was undertaken with 100 single-family households across the city of London, Ontario, Canada to determine the quantity and composition of household food waste disposed in June 2020, during the first wave of the COVID-19 pandemic. This study examines how household demographic, socioeconomic, and neighbourhood food environment characteristics influence household food wasting. On average, each household sent 2.81 kg of food waste to landfill per week, of which 52% was classified as avoidable food waste and 48% as unavoidable food waste. The quantity and composition of household food waste was found to be strongly influenced by the number of people and children in a household, and somewhat influenced by socioeconomic factors and neighbourhood food environment characteristics, including the availability, density, and proximity of retail food outlets.

Outcome evaluation of fruits and vegetables distribution interventions in schools: a systematic review and meta-analysis.

OBJECTIVE: Fruits and vegetables (FV) distribution interventions have been implemented as a public health strategy to increase children's intake of FV at school settings. The purpose of this review was to examine whether snack-based FV distribution interventions can improve school-aged children's consumption of FV. DESIGN: Systematic review and meta-analysis of articles published in English, in a peer-reviewed journals, were identified by searching six databases up to August 2020. Standardised mean differences (SMD) and 95 % CI were calculated using a random effects model. Heterogeneity was quantified using I2 statistics. SETTING: Population-based studies of interventions where the main focus was the effectiveness of distributed FV as snacks to schoolchildren in North America, Europe and Pacific were included. RESULTS: Forty-seven studies, reporting on fifteen different interventions, were identified; ten studies were included in the meta-analysis. All interventions were effective in increasing children's consumption of FV, with only one intervention demonstrating a null effect. Pooled results under all classifications showed effectiveness in improving children's consumption of FV, particularly for multi-component interventions at post-intervention (SMD 0·20, 95 % CI 0·13, 0·27) and free distribution interventions at follow-up (SMD 0·19, 95 % CI 0·12, 0·27). CONCLUSIONS: Findings suggest that FV distribution interventions provide a promising avenue by which children's consumption can be improved. Nonetheless, our results are based on a limited number of studies, and further studies should be performed to confirm these results. More consistent measurement protocols in terms of rigorous study methodologies, intervention duration and follow-up evaluation are needed to improve comparability across studies.

Fat-Free Mass Index Controlled for Age and Sex and Malnutrition Are Predictors of Survival in Interstitial Lung Disease.

BACKGROUND: Literature focusing on nutritional variables and survival in interstitial lung disease (ILD) is limited by its focus on weight and BMI and has not considered body composition. OBJECTIVES: The primary objective of this study was to examine whether body composition measures, specifically fat-free mass index z-score (z-FFMI) and body fat mass index z-score (z-BFMI), were predictors of survival in fibrotic ILD patients. The second objective was to examine if nutrition status was a predictor of survival. METHOD: Seventy-eight outpatients diagnosed with fibrotic ILD were recruited in this cross-sectional study. Body composition data using dual frequency bioelectrical impedance analysis (BodyStat 1500MD; UK) and nutrition status using the subjective global assessment (SGA) were determined. To control for age and sex, z-FFMI and z-BFMI were calculated using population means. Participant charts were reviewed for diagnosis, age, disease severity, and exercise capacity. RESULTS: Age (HR 1.08, 95% CI [1.03-1.13], p < 0.01), BMI (HR 0.90, 95% CI [0.84-0.97], p < 0.01]), z-FFMI (HR 0.70, 95% CI [0.56-0.87], p = 0.02), z-BFMI (HR 0.74, 95% CI [0.57-0.96], p < 0.01), 6-min walk distance (6MWD) (HR 0.99, 95% CI [0.99-1.00], p < 0.01), percent predicted diffusing capacity for carbon monoxide (%DLco) (HR 0.93, 95% CI [0.89-0.97], p < 0.01), and severe malnutrition (SGA-C) (HR 6.98, 95% CI [2.00-24.27], p < 0.01) were significant predictors of survival. When controlled for exercise capacity and disease severity, z-FFMI and severe malnutrition were significant predictors of survival independent of %DLco. CONCLUSION: z-FFMI and severe malnutrition were significant predictors of survival in fibrotic ILD patients independent of disease severity.

Using the Food Skills Questionnaire (FSQ) to Evaluate a Cooking Intervention for University Students: A Pilot Study.

Purpose: To pilot test the Food Skills Questionnaire (FSQ) to evaluate a cooking intervention.Methods: Students attending Western University were invited to participate in 3 cooking classes over a 3-month period. All participants were asked to complete the FSQ pre- and post-intervention. The FSQ evaluated food skills in 3 domains-Food Selection and Planning, Food Preparation, and Food Safety and Storage-with a maximum score of 100 per domain. Domain scores were then computed as a weighted average for the Total Food Skills Score out of 100. Open-ended questions assessed participants' perceptions of the classes.Results: Forty-four students participated. There was a significant increase in food planning (70.6 ± 13.5-77.6 ± 14.3, P < 0.01), food preparation (67.5 ± 14.0-74.9 ± 12.9, P < 0.01), food safety (78.0 ± 9.9-80.8 ± 13.0, P = 0.04), and total food skills (71.9 ± 8.9-77.8 ± 10.6, P < 0.01) post-intervention. Content analysis of open-ended questions indicated that participants enjoyed healthy recipes, supportive Peer Educators, discussions, the cooking experience, socializing, and the safe environment.Conclusions: The FSQ shows strong potential for evaluating basic (e.g., peeling, chopping, slicing) to intermediate (e.g., meal planning) food skills in an effective and feasible manner. It can also capture changes in specific domains, allowing the development of more focused nutrition education and skills-based interventions.

A Review of Statistical Reporting in Dietetics Research (2010-2019): How is a Canadian Journal Doing?

Despite the widespread use of statistical techniques in quantitative research, methodological flaws and inadequate statistical reporting persist. The objective of this study is to evaluate the quality of statistical reporting and procedures in all original, quantitative articles published in the Canadian Journal of Dietetic Practice and Research (CJDPR) from 2010 to 2019 using a checklist created by our research team. In total, 107 articles were independently evaluated by 2 raters. The hypothesis or objective(s) was clearly stated in 97.2% of the studies. Over half (51.4%) of the articles reported the study design and 57.9% adequately described the statistical techniques used. Only 21.2% of the studies that required a prestudy sample size calculation reported one. Of the 281 statistical tests conducted, 88.3% of them were correct. P values >0.05-0.10 were reported as "statistically significant" and/or a "trend" in 11.4% of studies. While this evaluation reveals both strengths and areas for improvement in the quality of statistical reporting in CJDPR, we encourage dietitians to pursue additional statistical training and/or seek the assistance of a statistician. Future research should consider validating this new checklist and using it to evaluate the statistical quality of studies published in other nutrition journals and disciplines.

Total Daily Production and Periodicity of Melatonin Metabolite in Critically Ill Children.

OBJECTIVES: To determine whether total daily 6-sulfatoxymelatonin excretion and diurnal variation of melatonin secretion was maintained during the early phase of PICU admission through examination of the melatonin urinary metabolite, 6-sulfatoxymelatonin. DESIGN: Exploratory prospective, observational study. SETTING: Twelve-bed medical-surgical PICU of a Children's Hospital. PATIENTS: Fifty children 3 months to 18 years old enrolled within 24 hours of PICU admission with access for urinary sampling. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Urine samples were collected at 4-hour intervals for 24 hours and stored at -80C. 6-sulfatoxymelatonin was determined in duplicate by direct enzyme-linked immunosorbent assay. Patients were heterogeneous for diagnosis, had a mean age of 8.1 years (SD = 6.1 yr), and median (interquartile range) Pediatric Risk of Mortality III of 10 (4-13). Mean (SD) total daily 6-sulfatoxymelatonin production was 30.0 µg (25.6 µg) for the first 24 hours, which did not differ significantly from the means on days 2 (p = 0.56) or 3 (p = 0.29), and was similar to literature controls. Mean 6-sulfatoxymelatonin production for the population fit a periodic function well, with a reliable amplitude of 326 ng/hr and peak excretion from 04:00 to 08:00 (F = 4.4, p = 0.01), even when 6-sulfatoxymelatonin was corrected for body weight (F = 3.4, p = 0.03) and when sedation was included in the model (F = 3.95, p = 0.004). There was no significant correlation between lighting and 6-sulfatoxymelatonin excretion at any time period (R values: 0.11-0.25, p = 0.10-0.94). Mean 6-sulfatoxymelatonin excretion did not fit the model for a periodic function well for the subpopulations studied (sepsis [n = 18, F = 1.1, p = 0.32], respiratory failure requiring deep sedation [n = 10, F = 0.4, p = 0.66], and neurologic injury [n = 7, F = 0.6, p = 0.55]). CONCLUSIONS: Total daily and diurnal variation of 6-sulfatoxymelatonin excretion is heterogeneously maintained early in pediatric critical illness. However, this may not hold true for specific diagnostic categories.

Comparison of Regularly Scheduled Ibuprofen Versus "Pro Re Nata" for Ankle Sprains in Children Treated in the Emergency Department: A Randomized Controlled Trial.

OBJECTIVE: We compared pain and degree of disability in patients with acute ankle sprains receiving regular scheduled ibuprofen versus pro re nata (PRN). METHODS: This study is a randomized single-blinded controlled trial of children aged 7 to 17 years presenting with acute ankle sprain to an emergency department. Patients were randomized to receive 10 mg/kg of ibuprofen per dose (maximum 600 mg) every 6 hours regular scheduled versus PRN. Outcome measures included a 100-mm visual analog scale pain and degree of disability at day 4. A sample size of 72 children had a power of 80% to detect a clinically meaningful difference of 20 mm between the regular and PRN group. RESULTS: We randomly assigned 99 patients to receive regular scheduled (n = 50) or PRN (n = 49) ibuprofen. Pain scores and degree of disability at day 4 showed no significant differences between groups. The rate of reported adverse effects was higher in the regular scheduled group (11.4% vs 9.5%) versus the PRN group. CONCLUSIONS: Our study suggests that there is little benefit from routinely using a regular scheduled ibuprofen regimen for acute pediatric ankle sprains.
