Background: Youth mental health is a growing concern in research, practice, and policy. Practice standards, guidelines, or strategies provide an invisible infrastructure that fosters equity, quality, and safety, potentially addressing inconsistencies and more effectively attending to the mental wellness of Black youth as a particular population of concern. This scoping review aimed to address the following question: What standards exist for the delivery of mental health services to Black youth in community, primary care, and educational settings? Due to a limited initial search yield on publications about standards for the delivery of mental health services for Black youth population, our goal was then to identify and map mental health standards, recommendations, or guidelines for the delivery of mental health services using the same settings to all youth. Methods: Searches were conducted in various databases, including PubMed/MEDLINE, PsycINFO, Embase, SocINDEX, CINAHL, Gender Studies Database, Social Services Abstracts, Sociological Abstracts, Scopus, Web of Science, and Google Scholar. Screening was independently conducted by two reviewers, with disagreements resolved by a third. Information extraction was performed by two independent reviewers. Results: Out of the 2,701 screened publications, 54 were included in this scoping review. Among them, 38.9% were published between 2020 and 2023, with 40.7% originating from the United States of America, 20.4% from the United Kingdom, and 13% from Canada. Concerning the settings, 25.9% of the publications focused on primary care, 24.1% on health care services, 20.4% on educational settings, and 3.7% on the community. Additionally, 25.9% were classified as general because recommendations were applicable to various settings. Attention-deficit/hyperactivity disorder (11.1%) was the most frequently considered specific condition, followed by autism spectrum disorder (9.3%) and depression (9.3%). However, 31.5% of the included references addressed mental health in general. Only three references provided specific recommendations for the Black population. Conclusions: Recommendations, guidelines, or standards for Black youth mental health services in community, primary care, or educational settings are scarce and limited to North American countries. This scoping review emphasizes the need to consider ethnicity when developing guidelines or standards to improve racial equity and reduce disparities in access to mental health services.

Background: Early post-discharge assessments for newborns are recommended. Virtual care has become more prevalent during the pandemic, providing an opportunity to better understand its impact on the quality of post-discharge newborn care. The objective of this study was to understand whether primary care visit modality (in-person vs. virtual) is associated with early newborn hospital readmissions and emergency department (ED) visits. Methods: We conducted a population-based, case-control study using linked health administrative databases between September 1, 2020 and March 31, 2022 in Ontario, Canada. We compared the modality of primary care visits among cases (hospital readmission within 14 days of life) and controls (newborns without a readmission), matched on infant sex, gestational age, and maternal parity. We included an alternative definition of cases as a composite of either a newborn hospital readmission or emergency department (ED) visit or in-hospital death within the first 14 days of life. Conditional logistic regression models were used to model odds ratios (ORs), comparing those exposed to a virtual visit versus in-person visit, adjusting for infant birth weight, birth hospitalization length of stay, neighbourhood level material deprivation, rurality and presence of active maternal comorbidities. Results: Among 73,324 eligible newborns, 2,220 experienced a hospital readmission within 14 days of life and were matched to 8,880 controls. Jaundice was the primary reason for readmission (75% of readmissions). Compared to newborns who were seen in-person post-discharge, newborns who were seen virtually had higher odds of hospital readmission (adjusted odds ratio [aOR] 1.41 (95% CI 1.09, 1.83); the magnitude of effect was not different using the composite outcome (aOR 1.35, 95% CI 1.05, 1.75). Conclusions: Newborns who receive a virtual post-discharge visit are more likely than those who receive an in-person visit to require hospital readmission. [ABSTRACT FROM AUTHOR]

Background: Marketing of unhealthy foods to children on digital media significantly impacts their dietary preferences and contributes to diet-related noncommunicable diseases. Canadian children spend a significant amount of time on digital devices and are frequently exposed to unhealthy food marketing on social media, including by influencers with celebrity status who endorse products. This study aimed to examine the frequency, healthfulness, and power of unhealthy food marketing in posts by influencers popular with Canadian children on YouTube, Instagram and TikTok. Methods: The top 9 influencers popular amongst Canadian children aged 10–12 years were identified from the 2021 International Food Policy Study Youth Survey. A total of 2,232 Instagram, YouTube and TikTok posts made by these influencers between June 1st 2021 and May 31st 2022 were examined for instances of food marketing. Food products/brands were identified and frequencies were calculated for the number of posts promoting food products/brands, posts promoting products/brands classified as less healthy according to Health Canada's Nutrient Profile Model (2018) and marketing techniques utilized. Results: YouTube had the highest average rate of food marketing instances per post, at a rate of 1 food marketing instance every 0.7 posts, while TikTok and Instagram had instances every 10.2 posts and 19.3 posts, respectively. Overall, fast food restaurants was the most promoted food category (21%), followed by regular soft drinks (13%), snacks (11%), candy and chocolate (11%) and water (8%). The most frequently used marketing techniques were appeals to fun/cool (37%), the use of songs or music (28%) and the product being consumed (25%). In terms of healthfulness, 83% of the products/brands (87% of brands and 82% of products) promoted were classified as less healthy. Conclusions: Social media influencers play a substantial role in promoting unhealthy food products to children, primarily fast food items. Given the significant impact of such marketing on children, there is a need for ongoing government-led monitoring, and it is crucial to include social media and influencer marketing in marketing restrictions targeting children in Canada to safeguard this vulnerable demographic.

Introduction: Caring for children and youth with special health care needs (CYSHCN) is a significant undertaking for families. While respite care is intended to address this burden, demand continues to exceed supply. Exploring the perspectives of respite service providers (SPs) and stakeholders (SKs) provides unique insight into families' needs and respite care systems. Methods: We conducted semistructured interviews with 41 respite care SPs and SKs across four Canadian provinces to ascertain perspectives on current and ideal respite care for families of CYSHCN. The analysis included delineating units of meaning from the data, clustering units of meaning to form thematic statements and extracting themes. The second‐level analysis involved applying themes and subthemes to cross‐functional process maps. Findings: Participants noted the critical, but sometimes absent role of Community Service Workers, who have the ability to support families accessing and navigating respite care systems. SPs and SKs identified current respite systems as operating in crisis mode. New findings suggest an ideal respite care system would incorporate advocacy for families, empower families and value CYSHCN, their families and respite workers. Conclusion: The evidence of unmet respite care needs of families of CYSHCN across Canada has long been available. Our findings identifying respite system challenges and solutions can be used by funders and policymakers for planning and enhancing resources, and by healthcare professionals, respite care providers and SKs to understand barriers and take action to improve respite outcomes to meet the respite needs of all families and CYSHCN. Patient or Public Contribution: The research team is composed of patients, researchers, clinicians and decision‐makers along with our Family Advisory Committee (FAC) composed of members of families of CYSHNC. The FAC was formed and met regularly with research team members, knowledge users and collaborators throughout the study to provide input on design, review themes and ensure findings are translated and disseminated in a meaningful way.

Background Fluoride may be a developmental neurotoxicant at elevated exposures. We merged new data from a prospective Odense Child Cohort (OCC) with results from two previous birth cohort studies from Mexico and Canada to characterize the dose–effect relationship in greater detail. Methods The OCC contributed 837 mother–child pairs to the total of >1500. We measured creatinine-adjusted urine-fluoride concentrations in maternal urine samples obtained during late pregnancy. Child IQ was determined at age 7 years using an abbreviated version of the Wechsler Intelligence Scales for Children. Findings from the three cohorts were used to calculate the joint benchmark concentration (BMC) and the lower confidence limit (BMCL) after adjustment for covariables. Results In the OCC, urine-fluoride concentrations varied between 0.08 and 3.04 mg/l (median 0.52 mg/l) but were not significantly associated with full-scale IQ at age 7 years (β = 0.08; 95% confidence interval −1.14 to 1.30 for a doubling in exposure). No difference was apparent between boys and girls. In the OCC, the BMC was 0.92 mg/l, with a BMCL of 0.30 mg/l. The joint analysis of all three cohorts showed a statistically significant association between urine-fluoride and IQ, with a BMC of 0.45 mg/l (BMCL, 0.28 mg/l), slightly higher than the BMC previously reported for the two North American cohorts alone. Conclusions As the BMCL reflects an approximate threshold for developmental neurotoxicity, the results suggest that pregnant women and children may need protection against fluoride toxicity.

Background: Little is known about the impact of the COVID-19 pandemic on families of children with chronic life-limiting conditions who died during the COVID-19 pandemic. Methods: In this qualitative study, parents of a child (< 18 years) who died during the COVID-19 pandemic from an underlying chronic medical condition were interviewed to explore how the pandemic impacted end-of-life care and bereavement experiences. Parents of children followed by the pediatric palliative care service were recruited from a large children's hospital in eastern Canada. Results: Twenty bereaved parents, consisting of 12 mothers and 8 fathers, participated in individual interviews between January and December 2021. Findings identified impacts of the COVID-19 pandemic on children's end-of-life care, experiences in hospital and at home, and family bereavement processes and experiences. Most parents experienced substantial worry about their child's physical status and the additional risk of COVID-19 given her/his vulnerability. Parents also struggled to navigate public health protocols as they attended to their child's needs and their family's desire for engagement and support. Key facilitators that helped families cope included a strong network of formal and informal supports. Conclusion: Implications highlight the need to critically reflect on pandemic care in the context of co-occurring end-of-life processes. Findings amplify the need to balance necessary infection control practices with access to essential supports for families. [ABSTRACT FROM AUTHOR]

Simple Summary: Treatments used to cure childhood cancer can have negative long-term impacts on physical health and well-being. Here, we present the Alberta Childhood Cancer Survivorship Research Program, its foundational cohort, and descriptive statistics of outcomes ascertained through data linkage. To this end, 2580 survivors of childhood cancer were included in the cohort, the majority of which were male, diagnosed between the ages of 0 and 4 years, and had leukemia, central nervous system tumor, or lymphoma. By the study exit date, the median time since diagnosis was 5.5 years overall and 10.4 years for 5-year survivors. During the follow-up time, 82 subsequent cancers were diagnosed, 20,355 inpatient and 555,425 ambulatory/outpatient events occurred, 606,773 claims were reported, and 437 survivors died. The results from this research program seek to inform and improve clinical care and reduce cancer-related sequelae. Adverse outcomes after childhood cancer have been assessed in a range of settings, but most existing studies are historical and ascertain outcomes only after 5-year survival. Here, we describe the Alberta Childhood Cancer Survivorship Research Program and its foundational retrospective, population-based cohort of Albertan residents diagnosed with a first primary neoplasm between the ages of 0 and 17 years from 1 January 2001 to 31 December 2018. The cohort was established in collaboration with the Alberta Cancer Registry and Cancer in Young People in Canada program and has been linked to existing administrative health databases and patient-reported outcome questionnaires. The cohort comprised 2580 survivors of childhood cancer, 1379 (53.4%) of whom were 5-year survivors. Approximately 48% of the cohort was female, 47% of the cohort was diagnosed between 0 and 4 years of age, and the most frequent diagnoses were leukemias (25.4%), central nervous system tumors (24.0%), and lymphomas (14.9%). Detailed treatment information was available for 1741 survivors (67.5%), with manual abstraction ongoing for those with missing data. By the study exit date, the median time since diagnosis was 5.5 years overall and 10.4 years for 5-year survivors. During the follow-up time, 82 subsequent primary cancers were diagnosed, 20,355 inpatient and 555,425 ambulatory/outpatient events occurred, 606,773 claims were reported, and 437 survivors died. The results from this research program seek to inform and improve clinical care and reduce cancer-related sequelae via tertiary prevention strategies. [ABSTRACT FROM AUTHOR]

Training staff and volunteers is an important aspect of successful program implementation. This paper follows Part A of an evaluation of the Special Olympics Canada (SOC) Coaching Young Athletes Training course. Consistent with Kirkpatrick's four-level model of training evaluation, Part A evaluated program leaders' reactions to (level 1) and immediate learning from (level 2) the training. This Part B paper covers "on the job" behavior (level 3). In-depth semi-structured interviews were conducted with youth program leaders (n = 11) from eight provinces. Overall, participants felt that more training related to working with children with autism and promoting positive athlete behavior was needed. The findings also lead us to suggest that program leaders need to develop a more fulsome understanding of how to foster skill mastery, including how to practice the same skill in many and varied ways.

Background: As a result of the public health measures put in place during the COVID-19 pandemic in Canada, many health services, including those for the treatment of eating disorders, were provided at a distance. This study aims to describe the adaptations made in specialized pediatric eating disorder programs in Canada and the impact of these adaptations on health professionals' experience of providing care. Methods: A mixed-methods design was used to survey healthcare professionals working in specialized pediatric eating disorder programs about adaptations to treatment made during the pandemic and the impact of these adaptations on their experience of providing care. Data were collected between October 2021 and March 2022 using a cross-sectional survey comprising 25 questions and via semi-structured interviews. Quantitative data were summarized using descriptive statistics and qualitative data were interpreted using qualitative content analysis. Results: Eighteen healthcare professionals in Canada completed the online survey, of whom six also participated in the semi-structured interviews. The cross-sectional survey confirmed that, unlike in pre-pandemic times, the majority of participants provided medical care (15/18) and mental health care (17/18) at a distance during the pandemic, with most participants using telephone (17/18) and videoconferencing (17/18). Most (16/18) health professionals indicated that virtual care would continue to be used as a tool in pediatric ED treatment after the pandemic. Participants used a combination of virtual and in-person care, with most reporting weighing patients both in clinic (16/18) and virtually (15/18). Qualitative content analysis generated five themes: (1) responding to increased demand with insufficient resources; (2) adapting to changes in care due to the COVID-19 pandemic; (3) dealing with uncertainty and apprehension; (4) virtual care as an acceptable and useful clinical tool, and (5) optimal conditions and future expectations. Most interview participants (5/6) had globally positive views of virtual care. Conclusions: Providing virtual multidisciplinary treatment for children and adolescents with eating disorders seemed feasible and acceptable to professionals during the pandemic. Moving forward, focusing on health professionals' perspectives and providing appropriate training in virtual interventions is essential given their central role in successful implementation and continued use of virtual and hybrid care models.

Background: Parents seek support on behalf of their transgender and gender nonconforming (TGNC) children. Previous qualitative studies explore the types of support parents seek inside and outside of healthcare settings. Healthcare providers often remain unprepared to effectively provide gender-affirming services to TGNC children and their accompanying parents and may benefit from learning about the support seeking experiences of parents with TGNC children. Aims: This paper summarized qualitative research studies that address the topic of parents seeking support on behalf of their TGNC children. We produced this report for healthcare providers to review to enhance gender-affirming services for parents and TGNC children. Methods: This paper outlines a qualitative metasummary of studies from the United States or Canada with data collected from parents of TGNC children. Data collection included the steps of journal runs, database searches, reference checks, and area scans. Data analysis involved the steps of extracting, editing, grouping, abstracting, and calculating the intensity and frequency effect sizes for finding statements from qualitative research study articles. Results: The results of this metasummary yielded two primary themes, six subthemes, and 24 total findings. The first primary theme of seeking guidance had three subthemes: educational resources, community networks, and advocacy efforts. The second primary theme of seeking healthcare had three subthemes: healthcare providers, mental healthcare, and general healthcare. Discussion: These findings provide information healthcare providers can use to inform their practice. These findings also highlight the importance of providers working collaboratively with parents when serving TGNC children. This article concludes with practical tips for providers.

Background: Primary healthcare services have principal responsibility for providing child and youth wellbeing and mental health services, but have lacked appropriate measurement instruments to assess the wellbeing of Indigenous children and youth or to evaluate the effectiveness of programs and services designed to meet their needs. This review assesses the availability and characteristics of measurement instruments that have been applied in primary healthcare services in Canada, Australia, New Zealand and the United States (CANZUS countries) to assess the wellbeing of Indigenous children and youth. Methods: Fifteen databases and 12 websites were searched in December 2017 and again in October 2021. Pre-defined search terms pertained to Indigenous children and youth, CANZUS country names, and wellbeing or mental health measures. PRISMA guidelines were followed, with eligibility criteria guiding screening of titles and abstracts, and selected full-text papers. Results are presented based on the characteristics of documented measurement instruments assessed according to five desirability criteria: development for Indigenous youth populations, adherence to relational strength-based constructs, administration by child and or youth self-report, reliability and validity, and usefulness for identifying wellbeing or risk levels. Results: Twenty-one publications were found that described the development and or use by primary healthcare services of 14 measurement instruments, employed across 30 applications. Four of the 14 measurement instruments were developed specifically for Indigenous youth populations, four focused solely on strength-based wellbeing concepts but none included all Indigenous wellbeing domains. Conclusion: There is a diversity of measurement instruments available, but few fit our desirability criteria. Although it is possible that we missed relevant papers and reports, this review clearly supports the need for further research to develop, refine or adapt instruments cross-culturally to measure the wellbeing of Indigenous children and youth.

PURPOSE: This study aimed to 1) investigate the convergent and discriminant validity, internal consistency, and test-retest reliability of the Canadian English version of the Computer-Based instrument for Low motor Language Testing (C-BiLLT-CAN), and 2) explore feasibility of the C-BiLLT assessment for children with cerebral palsy (CP) and complex communication needs in the Canadian health care context. METHODS: Eighty typically developing children between 1.5 and 8.5 years of age completed the C-BiLLT-CAN, the Peabody Picture Vocabulary Test-IV (PPVT-4), the receptive language sub-test of the New Reynell Developmental Language Scales (NRDLS), and/or the Raven's 2. Correlations between raw scores were calculated for estimates of convergent and discriminant validity. Internal consistency was calculated for all items and separately for items pertaining to vocabulary and grammar. To calculate the standard error of measurement (SEM) and intraclass correlation coefficient (ICC), 33 participants were re-tested with the C-BiLLT within three weeks. Feasibility was explored with nine participants with CP. RESULTS: C-BiLLT-CAN's convergent validity was good to excellent (Spearman's rho > 0.78) and discriminant validity was higher than hypothesized (Spearman's rho > 0.8). Internal consistency (Cronbach's alpha = 0.96), test-retest reliability (ICC > 0.9), and measurement error (SEM < 5%) were excellent. The feasibility study could not be fully completed due to the COVID-19 pandemic. Preliminary data demonstrated some technical and practical barriers for using the C-BiLLT in children with CP in Canada. CONCLUSION: The C-BiLLT-CAN showed good to excellent psychometric properties in a sample of typically developing children, indicating that it is an adequate test for measuring language comprehension in English-speaking Canadian children. Further research is needed to investigate the feasibility of the C-BiLLT-CAN in children with CP. [ABSTRACT FROM AUTHOR]

Background COVID-19 continues to disproportionately impact families of children with developmental disabilities (DD). There is an urgent need to understand these families' experiences, particularly those that face economic or social marginalization. This qualitative study sought to identify the experiences of families of children with DD during the COVID-19 pandemic. Methods Using phenomenology, in-depth interviews (IDIs) were conducted with caregivers and health care providers of children with DD living in a large urban Canadian city. Interviews were recorded, transcribed, and coded using inductive coding methods by two independent coders. Transcripts were analyzed within and across stakeholder groups using thematic analysis. Results A total of 25 IDIs were conducted in 2020. 3 main themes and 7 sub-themes emerged related to the experiences of parents and health care providers for children with DD: families reported difficulty adhering to public health measures leading to isolation and increased parental stress; restricted access to in-person services worsened behaviour and development; and worsened household financial security in already marginalized families. Conclusions Our study demonstrates that families of children with DD have been negatively impacted by the evolving environment from the COVID-19 pandemic, and even more so in those who face social and economic challenges. Public health restrictions have impaired the daily lives of these families and our study suggests that limitations to accessing in-person services may have long-lasting impacts on the well-being of families of children with DD. It is imperative that the unique needs of these families be considered and centred for future interventions. [ABSTRACT FROM AUTHOR]

Background Antibiotic prescription for uncomplicated upper respiratory tract infection (URTI) in children is not recommended but remains common. The primary objective was to evaluate the relationship between antibiotic prescription for URTI prior to age 2 and antibiotic prescription for URTI after age 2. It was hypothesized that antibiotic prescription for URTI in early childhood may increase the risk of antibiotic use for subsequent URTIs. The secondary objective was to investigate whether this relationship was different for acute otitis media (AOM), for which antibiotics may be indicated. Methods A prospective cohort study was conducted between December 2008 and March 2016 at 9 primary care practices in Toronto, Canada. Healthy children aged 0–5 years that met TARGet Kids! cohort eligibility criteria were included if they had at least one sick visit prior to age 2 and least one sick visit after age 2. Generalized Estimating Equation (GEE) models were used to evaluate this relationship while considering within-subject correlation. Results Of 2380 participants followed for a mean duration of 4.6 years, children who received an antibiotic prescription for URTI prior to age 2 had higher odds of receiving an antibiotic prescription for URTI in later childhood (adjusted odds ratio: 1.39; 95% confidence interval: 1.19 to 1.63; P  < .001). This relationship did not appear to be different for AOM compared to non-AOM URTI. Conclusion Antibiotic prescription for URTI before age 2 was associated with antibiotic prescription for URTI in later childhood. Reducing early life antibiotic prescription for URTI may be associated with reduction in antibiotic prescription for subsequent URTIs. [ABSTRACT FROM AUTHOR]

Objective: To translate and validate the Child Three-Factor Eating Questionnaire (CTFEQr17), assessing cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE), among French-speaking Canadian young individuals.Design: Phase 1 comprised a translation and the evaluation of the comprehension of the questionnaire. Phase 2 comprised a confirmatory factor analysis (CFA), the evaluation of internal consistency (Cronbach's α), test-retest reliability (intra-class correlation coefficients (ICC)) and construct validity, including correlations among the CTFEQr17 and Eating Attitudes Test (EAT-26), anthropometrics, dietary intake and diet quality.Setting: Primary and secondary schools, Québec City, Canada.Participants: Phases 1 and 2 included 20 (40 % boys, mean age 11·5 (sd 2·4) years) and 145 (48 % boys, mean age 11·0 (sd 1·9) years) participants, respectively.Results: Phase 1 resulted in the questionnaire to be used in Phase 2. In Phase 2, the CFA revealed that the seventeen item, three-factor model (CTFEQr17) provided an excellent fit. Internal consistency was good (Cronbach's α: 0·81-0·90). Test-retest reliability was moderate to good (ICC = 0·59, (95 % CI 0·48, 0·70), ICC = 0·78, (95 % CI 0·70, 0·84), ICC = 0·50, (95 % CI 0·38, 0·62) for CR, UE and EE, respectively). CR correlated with EAT-26 score (r = 0·43, P < 0·0001). UE and EE correlated negatively with BMI Z-scores (r = -0;·26, P = 0·003; r = -0;·19, P = 0·03, respectively). CR correlated with the proportion of energy intake from protein and diet quality (r = 0·18, P = 0·04; r = 0·20, P = 0·02, respectively).Conclusion: The CTFEQr17 is suitable to use among French-speaking Canadian young individuals.

Background: Vitamin D status at birth is reliant on maternal-fetal transfer of vitamin D during gestation.Objectives: We aimed to examine the vitamin D status of newborn infants in a diverse population and to subsequently identify the modifiable correlates of vitamin D status.Methods: In this cross-sectional study, healthy mother-infant dyads (n = 1035) were recruited within 36 h after term delivery (March 2016-March 2019). Demographic and lifestyle factors were surveyed. Newborn serum 25-hydroxyvitamin D [25(OH)D] was measured (standardized chemiluminescence immunoassay) and categorized as deficient [serum 25(OH)D <30 nmol/L] or adequate (≥40 nmol/L). Serum 25(OH)D was compared among categories of maternal characteristics using ANOVA; each characteristic was tested in a separate model. Subgroups (use of multivitamins preconception and continued in pregnancy compared with during pregnancy only) were matched (n = 352/group) for maternal factors (ancestry, age, income, education, parity, and prepregnancy BMI) using propensity scores; logistic regression models were generated for odds of deficiency or adequacy.Results: Infants' mean serum 25(OH)D was 45.9 nmol/L (95% CI: 44.7, 47.0 nmol/L) (n = 1035), with 20.8% (95% CI: 18.3%, 23.2%) deficient and 60.7% (95% CI: 55.2%, 66.2%) adequate. Deficiency prevalence ranged from 14.6% of white infants to 41.7% of black infants. Serum 25(OH)D was higher (P < 0.0001) in infants of mothers with higher income, BMI < 25 kg/m2, exercise and sun exposure in pregnancy, and use of multivitamins preconception. In the matched-subgroup analysis, multivitamin supplementation preconception plus during pregnancy relative to only during pregnancy was associated with lower odds for vitamin D deficiency (ORadj: 0.55; 95% CI: 0.36, 0.86) and higher odds for adequate vitamin D status (ORadj: 1.47; 95% CI: 1.04, 2.07).Conclusions: In this study most newborn infants had adequate vitamin D status, yet one-fifth were vitamin D deficient with disparities between population groups. Guidelines for a healthy pregnancy recommend maternal use of multivitamins preconception and continuing in pregnancy. An emphasis on preconception use may help to achieve adequate neonatal vitamin D status.This trial was registered at clinicaltrials.gov as NCT02563015. [ABSTRACT FROM AUTHOR]

BACKGROUND: The gut microbiome is important in modulating health in childhood. Metal exposures affect multiple health outcomes, but their ability to modify bacterial communities in children is poorly understood. OBJECTIVES: We assessed the associations of childhood and perinatal blood metal levels with childhood gut microbiome diversity, structure, species, gene family-inferred species, and potential pathway alterations. METHODS: We assessed the gut microbiome using 16S rRNA gene amplicon sequencing and shotgun metagenomic sequencing in stools collected from 6- to 7-year-old children participating in the GESTation and Environment (GESTE) cohort study. We assessed blood metal concentrations [cadmium (Cd), manganese (Mn), mercury (Hg), lead (Pb), selenium (Se)] at two time points, namely, perinatal exposures at delivery (푁 = 70) and childhood exposures at the 6- to 7-y follow-up (푁 = 68). We used multiple covariate-adjusted statistical models to determine microbiome associations with continuous blood metal levels, including linear regression (Shannon and Pielou alpha diversity indexes), permutational multivariate analysis of variance (adonis; beta diversity distance matrices), and multivariable association model (MaAsLin2; phylum, family, species, gene family-inferred species, and pathways). RESULTS: Children's blood Mn and Se significantly associated with microbiome phylum [e.g., Verrucomicrobiota (coef = -0.305, 푞= 0.031; coef = 0.262, 푞= 0.084, respectively)] and children's blood Mn significantly associated with family [e.g., Eggerthellaceae (coef = -0.228, 푞= 0.052)]-level differences. Higher relative abundance of potential pathogens (e.g., Flavonifractor plautii), beneficial species (e.g., Bifidobacterium longum, Faecalibacterium prausnitzii), and both potentially pathogenic and beneficial species (e.g., Bacteriodes vulgatus, Eubacterium rectale) inferred from gene families were associated with higher childhood or perinatal blood Cd, Hg, and Pb (푞< 0.1). We found significant negative associations between childhood blood Pb and acetylene degradation pathway abundance (푞< 0.1). Finally, neither perinatal nor childhood metal concentrations were associated with children's gut microbial inter- and intrasubject diversity. DISCUSSION: Our findings suggest both long- and short-term associations between metal exposure and the childhood gut microbiome, with stronger associations observed with more recent exposure. Future epidemiologic analyses may elucidate whether the observed changes in the microbiome relate to children’s health. [ABSTRACT FROM AUTHOR]

Background: Dietary inequities in childhood may shape dietary and health inequities across the life course. Quantifying the magnitude and direction of trends in absolute and relative gaps and gradients in diet quality according to multiple indicators of socioeconomic position (SEP) can inform strategies to narrow these inequities.Objectives: We examined trends in absolute and relative gaps and gradients in diet quality between 2004 and 2015 according to 3 indicators of SEP among a nationally representative sample of children in Canada.Methods: Data from children (aged 2-17 y; n = 18,670) who participated in the cross-sectional Canadian Community Health Survey-Nutrition in 2004 or 2015 were analyzed. SEP was based on total household income, household educational attainment, and neighborhood deprivation. Dietary intake data from 1 interviewer-administered 24-h dietary recall were used to derive a Healthy Eating Index-2015 (HEI-2015) score for each participant as a measure of diet quality. Inequities in diet quality were quantified using 4 indices: absolute and relative gaps (between highest and lowest SEP) and absolute (Slope Index of Inequality) and relative gradients (Relative Index of Inequality). Overall and age-stratified multivariable linear regression and generalized linear models examined trends in HEI-2015 scores between 2004 and 2015.Results: Although mean HEI-2015 total scores improved from 52.3 to 57.3 (maximum 100 points; P < 0.001), absolute and relative gaps and gradients in diet quality remained mostly stable for all 3 SEP indicators. However, among children aged 6-11 y, absolute and relative gradients in diet quality according to household educational attainment and neighborhood deprivation widened.Conclusions: The diet quality of children in Canada was poor and inequitably patterned in 2004 and 2015. Although mean diet quality improved between 2004 and 2015, absolute and relative gaps and gradients in diet quality persisted, with some evidence of widening absolute and relative gradients among 6- to 11-y-olds.

Background: Adequate iodine intake is important for children and women of childbearing age because iodine is vital for fetal brain development and early life.Objective: Iodine status of children (n = 1875), adolescents (n = 557), and women of childbearing age (n = 567) was assessed using urinary iodine concentrations (UIC) from duplicate spot samples collected in the Canadian Health Measures Survey, cycle 5 (2016-2017).Methods: Daily iodine intakes were estimated from urinary iodine and creatinine concentrations using a formula based on iodine absorption and predicted 24-h creatinine excretion. Usual UIC and iodine intakes, adjusted for within-person variation, were estimated using the National Cancer Institute method. Iodine status was assessed by 1) comparing median UIC with WHO/UNICEF/ICCIDD reference ranges and 2) estimating the prevalence of inadequate and excessive intakes using the estimated average requirement (EAR) and tolerable upper intake level (UL) cut-point method, respectively.Results: Median UIC for males and females 6-11 or 12-19 y old were ≥100 μg/L, the lower cutoff for adequate intakes. For women 20-39 y old, the median UIC of an unadjusted sample was 81 μg/L (95% CI: 67, 95) and for the usual UIC was 108 μg/L (95% CI: 84, 131). The percentage of children 3 y old with iodine intake ≥EAR was 82% (95% CI: 75, 89). The corresponding estimates for males 4-8, 9-13, and 14-18 y old were 93% (95% CI: 88, 97), 91% (95% CI: 87, 96), and 84% (95% CI: 76, 91), respectively. Estimates for females 4-8, 9-13, 14-18, and 19-39 y old were 86% (95% CI: 83, 89), 87% (95% CI: 80, 95), 68% (95% CI: 55, 80), and 68% (95% CI: 59, 76), respectively. For all sex-age groups, 91-100% had iodine intakes ≤UL.Conclusions: Iodine intakes may be insufficient for some women of childbearing age. Public health policies and programs should continue to recommend that all women who could become pregnant, or women who are pregnant or breastfeeding, take a daily multivitamin-mineral supplement containing iodine.

This study aimed to examine the association between breastfeeding and childhood obesity. A multinational cross‐sectional study of 4,740 children aged 9–11 years was conducted from 12 countries. Infant breastfeeding was recalled by parents or legal guardians. Height, weight, waist circumference, and body fat were obtained using standardized methods. The overall prevalence of obesity, central obesity, and high body fat were 12.3%, 9.9%, and 8.1%, respectively. After adjustment for maternal age at delivery, body mass index (BMI), highest maternal education, history of gestational diabetes, gestational age, and child's age, sex, birth weight, unhealthy diet pattern scores, moderate‐to‐vigorous physical activity, sleeping, and sedentary time, exclusive breastfeeding was associated with lower odds of obesity (odds ratio [OR] 0.76, 95% confidence interval, CI [0.57, 1.00]) and high body fat (OR 0.60, 95% CI [0.43, 0.84]) compared with exclusive formula feeding. The multivariable‐adjusted ORs based on different breastfeeding durations (none, 1–6, 6–12, and > 12 months) were 1.00, 0.74, 0.70, and 0.60 for obesity (Ptrend =.020) and 1.00, 0.64, 047, and 0.64 for high body fat (Ptrend =.012), respectively. These associations were no longer significant after adjustment for maternal BMI. Breastfeeding may be a protective factor for obesity and high body fat in 9‐ to 11‐year‐old children from 12 countries. [ABSTRACT FROM AUTHOR]

This paper draws on studies carried out in Canada (2016-2018) and the UK (2009-18) which explored the experiences of boys and men with Duchenne muscular dystrophy (DMD). Life expectancy with DMD has increased significantly and generations of men lead lives that many did not expect them to be leading. This paper searches our data to see if boys and men with DMD are supported to manage the precariousness of a life shorter than the 'norm'. Our studies had focuses on transition to adulthood, gender, social care, interactions in rehabilitation clinics, and managing conversations about death. The paper discusses how respondents framed DMD within time and the life-course. Our analysis suggests that ableist assumptions about time make the management of a challenging disease such as DMD even more challenging. We found little evidence of boys and men being helped to think through how to plan for a life expectancy that kept shifting. [ABSTRACT FROM AUTHOR]

Background: Parent experiences of caring for children with neurodevelopmental disease have been silenced and constrained by social, political and health influences. There is a need to co‐construct new meanings and interpretations of parenting a child with complex disabilities by having an increased understanding of the struggles and barriers for parents. Methods: A hermeneutic phenomenology approach was applied in this inquiry. Fifteen parents of children with rare neurodevelopmental diseases participated in semi‐structured interviews. Results: Parents experienced silencing or being silenced within interactions with health‐care and social care systems and providers. Interpretive thematic analysis revealed three insights: (a) parents experience a sense of disconnect and silencing as little is known or understood by health‐care providers about the experience of caring for children at home; (b) parents make strong efforts to be heard and acquire services within health and social systems as fighters, saviours and navigators; and (c) parents sacrifice themselves to the caregiving role and become therapists and caregivers to their medically fragile children at the cost of losing themselves as parents. Conclusion: An understanding of parents' experiences in caring for a child with a rare neurodevelopmental disease may provide insight to systemic health and social support challenges faced by families and mitigate appropriate and supportive policies and services.

BACKGROUND: Prenatal bisphenol A (BPA) exposure has been associated with adverse neurodevelopment in epidemiological studies. However, prior studies had limited statistical power to examine sex-specific effects, and few examined child cognition. OBJECTIVES: We estimated the association between prenatal BPA exposure and child neurobehavior at 3 y of age in a prospective cohort of 812 mothers and their children. METHODS: We measured BPA concentration in urine samples collected at ∼12 wk gestation among women enrolled in a 10-city Canadian cohort study. At approximately 3 y of age, we assessed children's cognitive abilities with the Wechsler Primary and Preschool Scale of Intelligence™-III (WPPSI-III) and two scales of the Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P). Parents reported children's behavior using the Behavior Assessment System for Children-2 (BASC-2) and the Social Responsiveness Scale™-2 (SRS-2). We estimated covariate-adjusted differences in neurobehavioral outcomes with a doubling in BPA concentration and sex-specific associations. RESULTS: BPA was not associated with WPPSI-III scores; child sex did not modify these associations. The association between BPA and BRIEF-P scores was modified by child sex (BPA×sex p-values≤0.03). For example, a doubling of BPA concentration was associated with 1-point (95% CI: 0.3, 1.7) poorer working memory in boys and 0.5-point (95% CI: -1.1, 0.1) better scores in girls. BPA was not associated with most BASC-2 scales; however, it was associated with more internalizing and somatizing behaviors in boys, but not in girls (BPA×sexp-values≤0.08). A doubling of BPA concentration was associated with poorer SRS-2 scores [β=0.3 ( 95% CI: 0, 0.7)]; this association was not modified by sex. CONCLUSION: Prenatal urinary BPA concentration was associated with some aspects of child behavior in this cohort, and some associations were stronger among boys. [ABSTRACT FROM AUTHOR]

Background: The Child and Youth Mental Health (ChYMH) assessment system was developed by interRAI (i.e., an international collective of researchers and clinicians from over thirty countries) in response to the unprecedented need for a coordinated approach to delivery of children's mental health care. Many interRAI instruments are used across Canada and internationally, but the ChYMH represents the first assessment specifically for children and youth. In the present paper, a short overview of the development process of the ChYMH is provided, and then the psychometric properties of several embedded scales on the ChYMH are examined.Methods: Participants included 1297 children and youth and their families who completed the ChYMH after being referred to mental health agencies within Ontario, Canada. In addition, smaller subsets of participants (N = 48-53) completed additional criterion measures, including the Social Skills Improvement System (SSIS), the Child and Adolescent Functional Assessment Scale (CAFAS), the Child Behavior Checklist (CBCL), and the Brief Child and Family Phone Interview (BCFPI).Results: Results demonstrated that the ChYMH subscales had strong internal-consistency (Cronbach's higher than .70), and correlated well with the criterion measures.Conclusions: Findings support the clinical utility of the ChYMH for use among clinically referred children and youth. Implications for children's mental health assessment and practice are discussed. [ABSTRACT FROM AUTHOR]

Background: The Canadian 24-h movement guidelines were developed with the hope of improving health and future health outcomes in children and youth. The purpose of this study was to evaluate adherence to the 3 recommendations most strongly associated with health outcomes in new 24-h movement guidelines and their relationship with adiposity (obesity and body mass index z-score) across countries participating in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE). Methods: Cross-sectional results were based on 6128 children aged 9-11 years from the 12 countries of ISCOLE. Sleep duration and moderate-to-vigorous physical activity (MVPA) were assessed using accelerometry. Screen time was measured through self-report. Body weight and height were measured. Body mass index (BMI, kg ⋅ m-2) was calculated, and BMI z-scores were computed using age- and sex-specific reference data from the World Health Organization. Obesity was defined as a BMI z-score > +2 SD. Meeting the overall 24-h movement guidelines was defined as: 9 to 11 h/night of sleep, ≤2 h/day of screen time, and at least 60 min/day of MVPA. Age, sex, highest parental education and unhealthy diet pattern score were included as covariates in statistical models. Associations between meeting vs. not meeting each single recommendation (and combinations) with obesity were assessed with odds ratios calculated using generalized linear mixed models. A linear mixed model was used to examine the differences in BMI z-scores between children meeting vs. not meeting the different combinations of recommendations. Results: The global prevalence of children meeting the overall recommendations (all three behaviors) was 7%, with children from Australia and Canada showing the highest adherence (15%). Children meeting the three recommendations had lower odds ratios for obesity compared to those meeting none of the recommendations (OR = 0.28, 95% CI 0.18-0.45). Compared to not meeting the 24-h movement recommendations either independently or combined, meeting them was significantly associated with a lower BMI z-score. Whenever the MVPA recommendation was included in the analysis the odds ratios for obesity were lower. Conclusions: For ISCOLE participants meeting these 3 healthy movement recommendations the odds ratios of being obese or having high BMI z-scores were lower. However, only a small percentage of children met all recommendations. Future efforts should aim to find promising ways to increase daily physical activity, reduce screen time, and ensure an adequate night's sleep in children. Trial registration: The International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) was registered at ClinicalTrials.gov (Identifier NCT01722500) (October 29, 2012).

Background: Health Canada's Surveillance Tool (HCST) Tier System was developed in 2014 with the aim of assessing the adherence of dietary intakes with Eating Well with Canada's Food Guide (EWCFG). HCST uses a Tier system to categorize all foods into one of four Tiers based on thresholds for total fat, saturated fat, sodium, and sugar, with Tier 4 reflecting the unhealthiest and Tier 1 the healthiest foods. This study presents the first application of the HCST to examine (i) the dietary patterns of Canadian children, and (ii) the applicability and relevance of HCST as a measure of diet quality.Methods: Data were from the nationally-representative, cross-sectional Canadian Community Health Survey 2.2. A total of 13,749 participants aged 2-18 years who had complete lifestyle and 24-hour dietary recall data were examined.Results: Dietary patterns of Canadian children and adolescents demonstrated a high prevalence of Tier 4 foods within the sub-groups of processed meats and potatoes. On average, 23-31 % of daily calories were derived from "other" foods and beverages not recommended in EWCFG. However, the majority of food choices fell within the Tier 2 and 3 classifications due to lenient criteria used by the HCST for classifying foods. Adherence to the recommendations presented in the HCST was associated with closer compliance to meeting nutrient Dietary Reference Intake recommendations, however it did not relate to reduced obesity as assessed by body mass index (p > 0.05).Conclusions: EWCFG recommendations are currently not being met by most children and adolescents. Future nutrient profiling systems need to incorporate both positive and negative nutrients and an overall score. In addition, a wider range of nutrient thresholds should be considered for HCST to better capture product differences, prevent categorization of most foods as Tiers 2-3 and provide incentives for product reformulation.

BACKGROUND: Management of children's pain and anxiety in the emergency department is likely suboptimal. OBJECTIVE: To determine the availability of cirrrently used strategies in Canadian paediatric emergency departments. METHODS: A cross-sectional survey involving all centres of the Pediatric Emergency Research Canada group was performed. The primary outcome was the availability of specific procedures for pain and anxiety management for children in the emergency department. One person per centre was identified to complete the survey. Data were collected from October 2013 to January 2014 using an electronic survey tool. RESULTS: All 15 Pediatric Emergency Research Canada centres agreed to participate. The verbal numerical scale was widely used (80%) to assess pain. One-half of respondents (53%) had access to a child life specialist. The following techniques were available for minor procedures: television as a distraction tool (87% of respondents), topical anesthetic before intravenous needle insertion (73%) and positioning of the child on parent's lap (60%); most remaining centres reported that these could be easily implemented. Intravenous morphine was available at every centre. Intranasal fentanyl was available (60%) or considered to be easy to implement (33%). Few centres reported availability of clinical guidelines regarding pain for doctors (27%) and nurses (40%); all respondents considered them to be easy to implement. CONCLUSIONS: There was wide variation in paediatric pain and anxiety management strategies among tertiary care Canadian emergency departments. Several pain-reduction procedures (distraction, positioning on parent's lap, topical anesthetic, intranasal administration) were identified that could be easily implemented to address the gap.

Infants explore their environments through repetitive movements that are constrained or facilitated by the environmental context. In this study, we evaluated how skilled bouncers adapted to bouncing in systems with four different spring conditions (natural frequencies of 0.9, 1.15, 1.27 and 1.56 Hz). Trunk kinematics and vertical ground reaction forces (VGRFs) were recorded from three pre-walking infants (mean age 10.6 ± 0.9 months). Bounce frequency, trunk displacement, peak VGRF, percent of time on the ground and time to peak force as a function of time on the ground were analyzed. In addition, infant bounce frequencies were compared to measured oscillations of an inert mass equivalent to each infant's mass. All infants bounced above the natural frequency of the spring system in all conditions suggesting that they did not behave solely like mass-spring systems. Infants produced asymmetrical VGRF loading patterns suggesting that a timing component, such as bounce frequency, was regulated. Skilled infants consistently increased their bounce frequency as their vertical trunk displacement decreased; however, the mode for regulating bounce frequency differed from infant to infant.

BACKGROUND: Genetics may partially explain observed heterogeneity in associations between traffic-related air pollution and incident asthma. OBJECTIVE: Our aim was to investigate the impact of gene variants associated with oxidative stress and inflammation on associations between air pollution and incident childhood asthma. METHODS: Traffic-related air pollution, asthma, wheeze, gene variant, and potential confounder data were pooled across six birth cohorts. Parents reported physician-diagnosed asthma and wheeze from birth to 7-8 years of age (confirmed by pediatric allergist in two cohorts). Individual estimates of annual average air pollution [nitrogen dioxide (NO2), particulate matter ≤ 2.5 μm (PM2.5), PM2.5 absorbance, ozone] were assigned to each child's birth address using land use regression, atmospheric modeling, and ambient monitoring data. Effect modification by variants in GSTP1 (rs1138272/Ala114Val and rs1695/IIe105Val) and TNF (rs1800629/G-308A) was investigated. RESULTS: Data on asthma, wheeze, potential confounders, at least one SNP of interest, and NO2 were available for 5,115 children. GSTP1 rs1138272 and TNF rs1800629 SNPs were associated with asthma and wheeze, respectively. In relation to air pollution exposure, children with one or more GSTP1 rs1138272 minor allele were at increased risk of current asthma [odds ratio (OR) = 2.59; 95% CI: 1.43, 4.68 per 10 μg/m3 NO2] and ever asthma (OR = 1.64; 95% CI: 1.06, 2.53) compared with homozygous major allele carriers (OR = 0.95; 95% CI: 0.68, 1.32 for current and OR = 1.20; 95% CI: 0.98, 1.48 for ever asthma; Bonferroni-corrected interaction p = 0.04 and 0.01, respectively). Similarly, for GSTP1 rs1695, associations between NO2 and current and ever asthma had ORs of 1.43 (95% CI: 1.03, 1.98) and 1.36 (95% CI: 1.08, 1.70), respectively, for minor allele carriers compared with ORs of 0.82 (95% CI: 0.52, 1.32) and 1.12 (95% CI: 0.84, 1.49) for homozygous major allele carriers (Bonferroni-corrected interaction p-values 0.48 and 0.09). There were no clear differences by TNF genotype. CONCLUSIONS: Children carrying GSTP1 rs1138272 or rs1695 minor alleles may constitute a susceptible population at increased risk of asthma associated with air pollution. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Access to health care for medically uninsured immigrant and refugee children is a public health concern due to the consequences of delayed or substandard care for child development and health. OBJECTIVE: To explore possible differences in help-seeking and service delivery across migratory statuses, institutions and provinces. METHODS: A review was undertaken of 2035 emergency files of immigrant, refugee and undocumented children without provincial health care coverage who sought care at three major paediatric hospitals in Montreal (Quebec) and Toronto (Ontario) during 2008 and 2009. RESULTS: Refugee claimant children with Interim Federal Health Program benefits consulted for less urgent problems than the overall hospital population, except in one hospital that had a multicultural paediatric ambulatory clinic. Undocumented children and new permanent resident immigrant children within the three-month waiting period for provincial health care coverage were over-represented in the very urgent triage category and presented more often for injuries, trauma and mental health problems than did refugee claimant children. DISCUSSION/CONCLUSIONS: Wide interhospital differences suggest that the predicament of limited access to health care of these groups of vulnerable medically uninsured children needs to be addressed through further research to inform policies and develop training.

Background: The role of environmental exposure to lead as a risk factor for chronic kidney disease (CKD) and its progression remains controversial, and most studies have been limited by a lack of direct glomerular filtration rate (GFR) measurement. Objective: We evaluated the association between lead exposure and GFR in children with CKD. Methods: In this cross-sectional study, we examined the association between blood lead levels (BLLs) and GFR measured by the plasma disappearance of iohexol among 391 participants in the Chronic Kidney Disease in Children (CKiD) prospective cohort study. Results: Median BLL and GFR were 1.2 µg/dL and 44.4 mL/min per 1.73 m2, respectively. The average percent change in GFR for each 1-µg/dL increase in BLL was −2.1 (95% CI: −6.0, 1.8). In analyses stratified by CKD diagnosis, the association between BLL and GFR was stronger among children with glomerular disease underlying CKD; in this group, each 1-µg/dL increase in BLL was associated with a −12.1 (95% CI: −22.2, −1.9) percent change in GFR. In analyses stratified by anemia status, each 1-µg/dL increase in BLL among those with and without anemia was associated with a −0.3 (95% CI: −7.2, 6.6) and −4.6 (95% CI: −8.9, −0.3) percent change in GFR, respectively. Conclusions: There was no significant association between BLL and directly measured GFR in this relatively large cohort of children with CKD, although associations were observed in some subgroups. Longitudinal analyses are needed to examine the temporal relationship between lead and GFR decline, and to further examine the impact of underlying cause of CKD and anemia/hemoglobin status among patients with CKD.

Background. Use of complementary and alternative medicine (CAM) by children with cancer is high; however, pediatric best cases are rare. Objectives. To investigate whether best cases exist in pediatric oncology using a three-phase approach and to compare our methods with other such programs. Methods. In phase I, Children's Oncology Group (COG) oncologists were approached via email and asked to recall patients who were (i) under 18 when diagnosed with cancer, (ii) diagnosed between 1990 and 2006, (iii) had unexpectedly positive clinical outcome, and (iv) reported using CAM during or after cancer treatment. Phase II involved partnering with CAM research networks; patients who were self-identified as best cases were asked to submit reports completed in conjunction with their oncologists. Phase III extended this partnership to 200 CAM associations and training organizations. Results. In phase I, ten cases from three COG sites were submitted, and most involved use of traditional Chinese medicine to improve quality of life. Phases II and III did not yield further cases. Conclusion. Identification of best cases has been suggested as an important step in guiding CAM research. The CARE Best Case Series Program had limited success in identifying pediatric cases despite the three approaches we used. [ABSTRACT FROM AUTHOR]

Background: Children with Down syndrome (DS) are at high risk of infectious toxicity when treated with acute lymphoblastic leukemia chemotherapy protocols optimized in children without DS. Our objective was to determine if children with DS and acute myeloid leukemia (AML) have a different risk of infection when treated with chemotherapy protocols developed for children with DS compared to AML treatment protocols developed for children without DS. Methods: We conducted a retrospective, population-based cohort study that included DS children ? 18 years of age with de novo, non-M3 AML diagnosed between January 1995 and December 2004, and treated at 15 Canadian centers. Patients were monitored for infection from initiation of AML treatment until recovery from the last cycle of chemotherapy, conditioning for hematopoietic stem cell transplantation, relapse, persistent disease or death (whichever occurred first). Trained research associates abstracted all information from each site. Results: There were 31 children with DS included; median age was 1.7 (range 0.1-11.1) years. Eleven were treated according to a DS-specific protocol while 20 were treated with non-DS specific protocols. A total of 157 courses of chemotherapy were delivered. Microbiologically documented sterile site infection occurred in 11.9% and 14.3% of DS-specific and non-DS specific AML treatment courses respectively. Sepsis was rare and there were no infection-related deaths. In multiple regression, treatment with a DS-specific protocol was independently associated with a reduction in microbiologically documented sterile site infection (adjusted odds ratio (OR) 0.65, 95% confidence interval (CI) 0.42-0.99; P = 0.044), and clinically documented infection (adjusted OR 0.36, 95% CI 0.14-0.91; P = 0.031) but not bacteremia (adjusted OR 0.73, 95% CI 0.44-1.22; P = 0.231). Conclusions: Our study suggests that children with DS do not experience excessive infectious toxicity during treatment for AML compared to children without DS. Incorporation of DS-specific AML treatment protocols is associated with a more favorable infection profile for children with DS-AML. [ABSTRACT FROM AUTHOR]

Background: Since 2006, banning smoking in cars with children has become a rapidly growing tobacco control policy. However, to date, there have been few studies examining support and correlates of support for car smoking bans, and none of the existing studies have been international in nature. We conducted such a study among smokers in four countries. Methods: 6716 adult current smokers from the 2007 Wave of the International Tobacco Control Four Country Survey, a nationally representative, longitudinal cohort telephone survey of smokers in the USA, Canada, UK and Australia. Controlling for demographics, heaviness of smoking, smoking health knowledge/beliefs and quit intentions, we compared support and correlates of support for banning smoking in cars with children across the four countries. Results: The majority of smokers supported banning smoking in cars with children. Support was highest in Australia (83%), followed by the UK (75%) and Canada (74%); support was lower—but still high—in the USA (60%). Support was highest among smokers who: had stronger quit intentions, were lighter smokers, had lower education, had no children in the home, believed that cigarette smoke is dangerous to non-smokers and could cause asthma in children, and were concerned about modelling smoking to children. Conclusions: These findings indicate that a majority of smokers in the four countries support banning smoking in cars with children, and lend support to banning smoking in cars with children. Additionally, they suggest that support may be increased by educating smokers about the dangers of cigarette smoke exposure. [ABSTRACT FROM AUTHOR]

Recent technological advances have provided many youth with daily, almost continuous cell-phone and Internet connectivity through portable devices. Young people’s experiences with computer-mediated communication (CMC) and their views about how this form of communication affects their health have not been fully explored in the scientific literature. A purposeful maximum variation sample of young people (aged 11–15 years) across Ontario was identified, using key informants for recruitment. The young people participated in seven focus groups (involving a total of 40 adolescents), and discussed various aspects of health including the health impacts of CMC. Inductive content analysis of the focus group transcripts revealed two overarching concepts: first, that the relationship between health and the potential impacts of CMC is multidimensional; and secondly, that there exists a duality of both positive and negative potential influences of CMC on health. Within this framework, four themes were identified involving CMC and: (1) physical activity, (2) negative mental and emotional disturbance, (3) mindfulness, and (4) relationships. With this knowledge, targeted strategies for healthy technology use that draw on the perspectives of young people can be developed, and can then be implemented by parents, teachers, and youth themselves.
