A Systematic Review and Meta-Analysis: Child and Adolescent Healthcare Utilization for Eating Disorders During the COVID-19 Pandemic.

OBJECTIVE: To conduct a meta-analysis documenting healthcare service utilization rates for pediatric (age <19 years) eating disorders during compared to before the COVID-19 pandemic. METHOD: PsycINFO, MEDLINE, Embase, and Web of Science Core Collection were searched for studies published up to May 19, 2023. Studies with pediatric visits to primary care, inpatient, outpatient, and emergency department for eating disorders before and during the pandemic were included. This preregistered review (PROSPERO CRD42023413392) was reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were analyzed with random-effects meta-analyses. RESULTS: A total of 52 studies reporting >148,000 child and adolescent eating disorder-related visits to >300 health settings across 15 countries were included (mean age, 12.7 years; SD = 4.1 years; 87% girls). There was strong evidence of an increase in healthcare use for eating disorders during the pandemic (rate ratio [RR] = 1.54, 95% CI = 1.38-1.71). Moderator analysis revealed larger rate increases among girls (RR = 1.48, 95% CI = 1.28-1.71) compared to boys (RR = 1.24, 95% CI = 1.06-1.45) and for adolescents (age ≥12 to 19 years) (RR = 1.53, 95% CI = 1.29-1.81) compared to children (RR = 0.87, 95% CI = 0.53-1.43). Moderator analysis demonstrated strong evidence of increased use of emergency department (RR = 1.70, 95% CI = 1.48-1.97), inpatient (RR = 1.56, 95% CI = 1.33-1.84), and outpatient (RR = 1.62, 95% CI = 1.35-1.95) services, as well as strong evidence of increased rates of anorexia nervosa (RR = 1.48, 95% CI = 1.24-1.75). CONCLUSION: Healthcare use for pediatric eating disorders increased substantially during the COVID-19 pandemic, particularly among girls and adolescents. It is important to continue to monitor whether changes in healthcare use associated with acute pediatric mental distress are sustained beyond the COVID-19 pandemic.

A comparative effectiveness study of the breaking the cycle and Maxxine Wright intervention programs for substance-involved mothers and their children: study protocol.

BACKGROUND: Children of substance-involved mothers are at especially high risk for exposure to adverse childhood experiences (ACEs) and poor mental health and development. Early interventions that support mothers, children, and the mother-child relationship have the greatest potential to reduce exposure to early adversity and the mental health problems associated with these exposures. Currently, there is a lack of evidence from the real-world setting demonstrating effectiveness and return on investment for intervention programs that focus on the mother-child relationship in children of substance-involved mothers. METHODS: One hundred substance-involved pregnant and/or parenting women with children between the ages of 0-6 years old will be recruited through the Breaking the Cycle and Maxxine Wright intervention programs, in Toronto, Ontario, Canada and Surrey, British Columbia, Canada, respectively. Children's socioemotional development and exposure to risk and protective factors, mothers' mental health and history of ACEs, and mother-child relationship quality will be assessed in both intervention programs. Assessments will occur at three time points: pre-intervention, 12-, and 24-months after engagement in the intervention program. DISCUSSION: There is a pressing need to identify interventions that promote the mental health of infants and young children exposed to early adversity. Bringing together an inter-disciplinary research team and community partners, this study aligns with national strategies to establish strong evidence for infant mental health interventions that reduce child exposure to ACEs and support the mother-child relationship. This study was registered with clinicaltrials.gov (NCT05768815) on March 14, 2023.

Examining the Relationship Between Screening for Postpartum Depression and Associated Child Health Service Utilization and Costs: A Study Using the All Our Families Cohort and Administrative Data.

INTRODUCTION: Despite a recognized association between maternal postpartum depression (PPD) and adverse child health outcomes, evidence examining the relationship between PPD symptoms and associated child health service utilization and costs remains unclear. In addition, there is a paucity of evidence describing the relationship between early identification of maternal PPD and associated health service utilization and costs for children. This study aims to address this gap by describing the secondary associations of screening for maternal PPD and annual health service utilization and costs for children over their first five years of life. METHODS: Mothers and children enrolled in the prospective All Our Families cohort were linked to provincial administrative data in Alberta, Canada. Multivariable generalized linear models were used to estimate the average annual inpatient, outpatient, physician, and total health service utilization and costs from a public health system perspective for children of mothers screened high risk for PPD, low/moderate risk for PPD, or unscreened. RESULTS: Total mean costs were greatest for children during their first year of life than other years. Those whose mothers were not screened had significantly lower costs compared to those whose mothers were screened low/moderate risk, despite equivalent health service utilization. DISCUSSION: Findings from this study describe the secondary associations of screening for maternal PPD using a public health system perspective. More research is required to fully understand variations in health costs for children across maternal PPD screening categories.

This study describes the relationship between maternal PPD screening status and annual child health service utilization and costs over the first five years of age. Findings from this administrative data study will support decision-makers in understanding the secondary effects associated with maternal PPD screening and inform future cost-effectiveness analyses of PPD screening interventions using a maternal-child health perspective.

Health Care Utilization and Costs in Lung Cancer Screening Participants-A Propensity-Matched Economic Analysis.

Introduction: Lung cancer screening (LCS) for high-risk populations has been firmly established to reduce lung cancer mortality, but concerns exist regarding unintended downstream costs. Methods: Mean health care utilization and costs were compared in the Alberta Lung Cancer Screening Study in a cohort undergoing LCS versus a propensity-matched control group who did not. Results: A cohort of 651 LCS participants was matched to 336 unscreened controls. Over the study period (mean 3.6 y), a modest increase in the number of claims (22.4 versus 21.9 per person-year [PY]; Δ 0.50 [95% confidence interval: 0.15-0.86], p = 0.006) and outpatient visits (4.01 versus 3.50 per PY; Δ 0.51 [0.37-0.65], p <0.0001), but not in inpatient admissions, was noted in the screened cohort. Claims payments, inpatient costs, and cancer care costs were similar in the screening arm versus the unscreened. Outpatient encounter costs per participant were higher in the screened group ($2662.18 versus $2040.67 per PY; Δ -$621.51 [-1118.05 to -124.97], p = 0.014). Removing the additional computed tomography screening examinations rendered differences not significant. Mean total costs were not significantly different at $6461.10 per PY in the screening group and $6125.31 in the unscreened group (Δ -$335.79 [-2009.65 to 1338.07], p = 0.69). Conclusions: Modest increases in outpatient costs are noted in individuals undergoing LCS, in part attributable to the screening examinations, without differences in overall health care costs. Health care costs and utilization seem otherwise similar in individuals participating in LCS and those who do not.

Developing non-response weights to account for attrition-related bias in a longitudinal pregnancy cohort.

BACKGROUND: Prospective cohorts may be vulnerable to bias due to attrition. Inverse probability weights have been proposed as a method to help mitigate this bias. The current study used the "All Our Families" longitudinal pregnancy cohort of 3351 maternal-infant pairs and aimed to develop inverse probability weights using logistic regression models to predict study continuation versus drop-out from baseline to the three-year data collection wave. METHODS: Two methods of variable selection took place. One method was a knowledge-based a priori variable selection approach, while the second used Least Absolute Shrinkage and Selection Operator (LASSO). The ability of each model to predict continuing participation through discrimination and calibration for both approaches were evaluated by examining area under the receiver operating curve (AUROC) and calibration plots, respectively. Stabilized inverse probability weights were generated using predicted probabilities. Weight performance was assessed using standardized differences of baseline characteristics for those who continue in study and those that do not, with and without weights (unadjusted estimates). RESULTS: The a priori and LASSO variable selection method prediction models had good and fair discrimination with AUROC of 0.69 (95% Confidence Interval [CI]: 0.67-0.71) and 0.73 (95% CI: 0.71-0.75), respectively. Calibration plots and non-significant Hosmer-Lemeshow Goodness of Fit Tests indicated that both the a priori (p = 0.329) and LASSO model (p = 0.242) were well-calibrated. Unweighted results indicated large (> 10%) standardized differences in 15 demographic variables (range: 11 - 29%), when comparing those who continued in the study with those that did not. Weights derived from the a priori and LASSO models reduced standardized differences relative to unadjusted estimates, with the largest differences of 13% and 5%, respectively. Additionally, when applying the same LASSO variable selection method to develop weights in future data collection waves, standardized differences remained below 10% for each demographic variable. CONCLUSION: The LASSO variable selection approach produced robust weights that addressed non-response bias more than the knowledge-driven approach. These weights can be applied to analyses across multiple longitudinal waves of data collection to reduce bias.

Priorities for research to support local authority action on health and climate change: a study in England.

BACKGROUND: Evidence is needed to support local action to reduce the adverse health impacts of climate change and maximise the health co-benefits of climate action. Focused on England, the study identifies priority areas for research to inform local decision making. METHODS: Firstly, potential priority areas for research were identified from a brief review of UK policy documents, and feedback invited from public and policy stakeholders. This included a survey of Directors of Public Health (DsPH) in England, the local government officers responsible for public health. Secondly, rapid reviews of research evidence examined whether there was UK evidence relating to the priorities identified in the survey. RESULTS: The brief policy review pointed to the importance of evidence in two broad areas: (i) community engagement in local level action on the health impacts of climate change and (ii) the economic (cost) implications of such action. The DsPH survey (n = 57) confirmed these priorities. With respect to community engagement, public understanding of climate change's health impacts and the public acceptability of local climate actions were identified as key evidence gaps. With respect to economic implications, the gaps related to evidence on the health and non-health-related costs and benefits of climate action and the short, medium and longer-term budgetary implications of such action, particularly with respect to investments in the built environment. Across both areas, the need for evidence relating to impacts across income groups was highlighted, a point also emphasised by the public involvement panel. The rapid reviews confirmed these evidence gaps (relating to public understanding, public acceptability, economic evaluation and social inequalities). In addition, public and policy stakeholders pointed to other barriers to action, including financial pressures, noting that better evidence is insufficient to enable effective local action. CONCLUSIONS: There is limited evidence to inform health-centred local action on climate change. More evidence is required on public perspectives on, and the economic dimensions of, local climate action. Investment in locally focused research is urgently needed if local governments are to develop and implement evidence-based policies to protect public health from climate change and maximise the health co-benefits of local action.

Creating Health Equity in Cancer Screening: Developing Outreach Strategies for Under-Screened Populations through Community Engagement.

Inequities in cancer screening were identified in Calgary, AB, by correlating low screening participation with higher material deprivation. This initiative sought to understand awareness of and barriers to breast, cervical and colorectal cancer screening to inform the co-design and implementation of an outreach strategy to increase screening awareness. Online focus groups with community members (n = 69) identified five themes, and interviews with community health workers (n = 21) identified four themes. The engagement phase led to a multi-component outreach strategy including a multilingual video series, a media campaign leveraging partner channels and a health worker information package with resources to assist with hosting community-based education sessions.

Maximizing maternal health and value for money in postpartum depression screening: a cost-effectiveness analysis using the All Our Families cohort and administrative data in Alberta, Canada.

BACKGROUND: Postpartum depression (PPD) affects 10-15% of women, is costly and debilitating, yet often remains undiagnosed. Within Alberta, Canada, screening is conducted at public health well child clinics using the Edinburgh Postnatal Depression Scale. If screened high-risk, women are offered referral to their family physicians for follow up diagnosis and treatment. METHODS: We developed a decision tree to estimate the cost-effectiveness of PPD screening versus not screening in Alberta over a two-year time horizon using a public healthcare payer perspective. Both the current practice (51% attending referral) and a scenario analysis (100% attending referral) are presented. RESULTS: Current practice results suggest screening leads to an incremental cost-effectiveness ratio (ICER) of $17,644 USD per quality adjusted life year (QALY). At a population-level, this resulted in an annual 813 (11%) additional cases diagnosed, 120 additional QALYs gained, and an additional cost of $2.1 million relative to not screening. With 100% attending referral, the ICER fell to $13,908 per QALY, resulting in an annual 1997 (27%) additional cases diagnosed, 249 additional QALYs gained, and an additional cost of $3.5 million relative to not screening. LIMITATIONS: We were unable to explore the cost-effectiveness of PPD screening versus not screening for secondary populations, including children. CONCLUSIONS: The results suggest screening may be most valuable when participation and compliance are maximized, where all women screened high-risk attend referral. This leads to greater value for money and increased maternal health gains across the population. Collaboration among public health and primary care services is encouraged to improve outcomes.

Health care service for families with children at early risk of developmental delay: an All Our Families cohort study.

AIM: This study examined children's health care service use, mothers' workforce participation, and mothers' community engagement based on children's risk of developmental delay. METHOD: We used data from the All Our Families study, a prospective pregnancy cohort. Ages and Stages Questionnaire (ASQ) scores at year 2 indicated risk of developmental delay. To investigate the impact of risk of developmental delay when children were not diagnosed, a sensitivity analysis excluded reports of neurodevelopmental disorder (NDD) diagnosis at year 3. Outcomes were maternal reports of children's health and allied health visits (and estimated costs), and maternal workforce participation and community engagement from year 2 to 3. RESULTS: Among 1314 mother-child dyads, 209 (16%) children were classified as being at risk of developmental delay by the ASQ, and 42 (3%) had a reported diagnosis of NDD. Risk of developmental delay was related to increased use of allied health care services (incidence risk ratio 5.04 [year 3]; 95% confidence interval 2.49-10.2) and health visits (incidence risk ratio 1.33 [year 3]; 95% confidence interval 1.14-1.54). The average expected allied health costs were greater for children at risk versus not at risk of developmental delay. However, when excluding children with reported diagnoses of an NDD from this analysis, increased service use and costs in the remaining at-risk population were not observed. Community engagement and workplace participation among families did not differ on the basis of risk of developmental delay. INTERPRETATION: These results suggest increased health care service use by families of children at risk of developmental delay is driven by those receiving a diagnosis of an NDD in the subsequent year. WHAT THIS PAPER ADDS: Early developmental delay risk was related to health care service use and costs. Diagnosis of neurodevelopmental disorder drove increased health care service use and costs. Early developmental delay risk did not relate to parental workforce participation. Early developmental delay risk did not relate to community engagement participation.

SERVICIO DE ATENCIÓN MÉDICA PARA FAMILIAS CON NIÑOS EN RIESGO TEMPRANO DE RETRASO EN EL DESARROLLO: UN ESTUDIO DE COHORTE DE TODAS NUESTRAS FAMILIAS: OBJETIVO: Este estudio examinó el uso del servicio de atención médica de los niños en riesgo de retraso en el desarrollo, y a su vez la participación de las madres en el mercado laboral y su participación comunitaria basada en el riesgo de los niños de presentar retraso en el desarrollo. MÉTODO: Utilizamos datos del estudio All Our Families, una cohorte de embarazo longitudinal. Las puntuaciones del Cuestionario de edades y etapas (ASQ) a los 2 años se usaron para identificar riesgo de retraso en el desarrollo. Para investigar el impacto del riesgo de retraso del desarrollo cuando los niños no fueron diagnosticados, un análisis de sensibilidad excluyó los informes de diagnóstico de trastornos del neurodesarrollo (NDD) a los 3 años. Los resultados se recolectaron de informes maternos de salud infantil y visitas de salud a diferentes profesionales de la salud (y costos estimados), y la participación materna en el mercado laboral y la participación materna en la comunidad entre el 2 a 3 año de vida de sus hijos. RESULTADOS: Entre 1.314 díadas madre-hijo, 209 (16%) niños fueron clasificados como en riesgo de retraso en el neurodesarrollo por el ASQ, y 42 (3%) tenían un diagnóstico informado de NDD. El riesgo de retraso en el desarrollo se relacionó con un mayor uso de servicios de atención médica por diversos profesionales de la salud (incidencia cociente de riesgos 5.04 [año 3]; Intervalo de confianza del 95% 2.49-10.2) y visitas de salud (riesgo de incidencia relación 1,33 [año 3]; 95% intervalo de confianza 1.14-1.54). La proyección de los costos promedio de salud aliada esperada fueron mayores para los niños en riesgo versus no en riesgo de retraso en el desarrollo. Sin embargo, al excluir a los niños con diagnósticos informados de un NDD de este análisis, no se observaron un aumento en el uso del servicio y los costos en la población en riesgo restante. Cuando se comparó la participación en la comunidad y la participación en el mercado laboral entre las familias, los resultados no difirieron en función del riesgo de retraso en el desarrollo de los niños. INTERPRETACIÓN: Estos resultados sugieren que el mayor uso de servicios de atención médica por parte de las familias de los niños en riesgo de retraso del desarrollo son impulsados por aquellos que reciben un diagnóstico de NDD en el año siguiente.

SERVIÇOS DE SAÚDE PARA FAMÍLIAS COM CRIANÇAS EM RISCO PRECOCE PARA ATRASO NO DESENVOLVIMENTO: UM ESTUDO DE COORTE TODAS AS NOSSAS FAMÍLIAS: OBJETIVO: Este estudo examinou o uso de serviços de saúde por crianças, participação das mães na força de trabalho, e engajamento das mães na comunidade com base no risco da criança para atraso no desenvolvimento. MÉTODO: Usamos dados do estudo All Our Families, uma coorte prospectiva de gestantes. Os escores no Questionário Idades e Fases (QIF) na idade de 2 anos indicou risco de atraso no desenvolvimento. Para investigar o impacto do risco para atraso no desenvolviemnto quando crianças não tinham diagnóstico, uma análise de sensibilidade excluiu os relatos de desordem neurodesenvolvimental (DND) na idade de 3 anos. Os desfechos foram os relatos maternos sobre a saúde da criança e visitas a serviços de saúde (com custos estimados), e a participação das mães na força de trabalho e engajamento na comunidade nos anos 2 e 3. RESULTADOS: Entre 1314 díades mãe-criança, 209 (16%) crianças foram classificadas como tendo risco para atraso no desenvolvimento, e 42 (3%) tiveram diagnóstico de DND. O risco de atraso no desenvolvimento foi relacionado a um aumento no uso de serviços aliados de saúde (razão do risco de incidência 5,04 [ano 3]; intervalo de confiança a 95% 2,49-10,2) e consultas de saúde (razão do risco de incidência 1,33 [ano 3]; intervalo de confiança a 95% 1,14-1,54). A média esperada dos custos dos serviços aliados de saúde foi maior para crianças de risco versus aquelas sem risco para atraso no desenvolvimento. No entanto, quando excluídas da análise as crianças com diagnóstico reportado de DND, o maior uso dos serviços e custos no restante da população de risco não foram observados. O engajamento na comunidade e participação na força de trabalho entre famílias não diferiu com base no risco para atraso do desenvolvimento. INTERPRETAÇÃO: Os resultados sugerem que o uso aumentado de serviços de saúde por famílias com crianças com risco para atraso no desenvolvimento é causado por aqueles que receberam diagnóstico de DND no ano subsequente.

Examining postpartum depression screening effectiveness in well child clinics in Alberta, Canada: A study using the All Our Families cohort and administrative data.

Affecting 10-15% of women, postpartum depression (PPD) can be debilitating and costly. While early identification has the potential to improve timely care, recommendations regarding the implementation of routine screening are inconsistent. In Alberta, screening is completed using the Edinburgh Postnatal Depression Scale during public health well child clinic visits. The objective of this study was to examine the effectiveness of screening in identifying, diagnosing and treating women at increased risk for PPD over the first year postpartum, compared to those unscreened. The All Our Families prospective pregnancy cohort was linked to public health, inpatient, outpatient, physician claims and community pharmaceutical data over the first year postpartum. Descriptive statistics and bivariate analyses examined differences in sample characteristics and PPD and non-PPD related utilization by screening category. Odds ratios and 95% confidence intervals for PPD diagnosis and mental health drugs dispensed were generated using crude and multivariable logistic regression models. Within our sample, 87% of the eligible population were screened, with 3% receiving a high-risk score, and 13% were unscreened. Compared to those unscreened, women screened high-risk had higher odds of being diagnosed with PPD (OR: 3.88, 95% CI: 2.18-6.92) and women screened low/moderate-risk had reduced odds of receiving a diagnosis (OR: 0.51, 95% CI: 0.35-0.74). High-risk women had an increased likelihood of diagnosis, higher PPD-related utilization and drugs dispensed compared to those unscreened. This information suggests that screening was effective at streamlining resources in Alberta. Future work should focus on evaluating the cost-effectiveness of PPD screening.

Supporting healthy pregnancies: Examining variations in nutrition, weight management and substance abuse advice provision by prenatal care providers in Alberta, Canada. A study using the All Our Families cohort.

BACKGROUND: Pregnancy is a critical time for fetal development, and education of women regarding healthy lifestyle choices is an important function for prenatal care providers, those that provide care to women during pregnancy. Within Canada, women choose to receive pregnancy care from one of a variety of publicly funded care providers. This study examines the association between the type of care provider(s) seen during pregnancy and the provision of advice related to nutrition, weight management and substance abuse. METHODS: Using data from the Alberta-based All Our Families prospective pregnancy cohort, we conducted bivariate and multivariate analyses to determine the likelihood of receiving advice related to nutrition, weight management, and substance abuse across provider(s) seen. RESULTS: Of 3341 women in our sample, 38% saw a single provider during pregnancy and 56% received care from multiple providers. Advice on nutrition was more likely to be provided across all providers, while weight management and substance abuse was less frequently and less consistently discussed. Relative to doctors in low-risk maternity clinics, midwives were most likely to provide nutrition (OR: 3.09, 95% CI: 1.19-8.01) and weight management (OR: 1.99, 95% CI: 1.13-3.50) advice to women. CONCLUSION: Findings suggest that the type of prenatal advice received by women depends on the provider(s) seen during pregnancy. Substance abuse was least likely to be discussed across providers, suggesting important implications given recent cannabis legalization.

Diversity in public views toward stem cell sources and policies.

Studies of public views on stem cell research have traditionally focused on human embryonic stem cells. With more recent scientific research on developing other stem cell sources, a series of focus group studies was undertaken with Canadian adults to examine their views on different stem cell sources (adult, umbilical cord blood, human embryonic stem cells, somatic cell nuclear transfer or SCNT, and interspecies nuclear transfer, or iSCNT). Views on three different policy models--a permissive, middle-of-the-road and restrictive policy approach--were also explored. Participants were recruited from several different social groups including patients, young adults, seniors, members of two ethnic communities, and a mixed group of adults. Participants were generally supportive of the use of adult stem cell sources. While there was also majority support for the use of hESC and SCNT, this was conditional on strict regulatory oversight. There was also majority support for a permissive policy which allows research on hESC and SCNT. General themes that cut across different groups included the potential cost of new technologies to the health care system, issues around who would gain access to these technologies, and trust in the scientific establishment and regulatory systems. A diversity of viewpoints was found as participants justified their positions on stem cell sources and policy approaches, showing more complexity and nuance than has been generally portrayed.

The stem cell research environment: a patchwork of patchworks.

Few areas of recent research have received as much focus or generated as much excitement and debate as stem cell research. Hope for the therapeutic promise of this field has been matched by social concern associated largely with the sources of stem cells and their uses. This interplay between promise and controversy has contributed to the enormous variation that exists among the environments in which stem cell research is conducted throughout the world. This variation is layered upon intra-jurisdictional policies that are also often complex and in flux, resulting in what we term a 'patchwork of patchworks'. This patchwork of patchworks and its implications will become increasingly important as we enter this new era of stem cell research. The current progression towards translational and clinical research among international collaborators serves as a catalyst for identifying potential policy conflict and makes it imperative to address jurisdictional variability in stem cell research environments. The existing patchworks seen in contemporary stem cell research environments provide a valuable opportunity to consider how variations in regulations and policies across and within jurisdictions influence research efficiencies and directions. In one sense, the stem cell research context can be viewed as a living experiment occurring across the globe. The lessons to be gleaned from examining this field have great potential for broad-ranging general science policy application.
