The association between household food insecurity and healthcare costs among Canadian children.

OBJECTIVE: To examine the relationship between household food insecurity and healthcare costs in children living in Ontario, Canada. METHODS: We conducted a cross-sectional, population-based study using four cycles of the Canadian Community Health Survey (2007-2008, 2009-2010, 2011-2012, 2013-2014) linked with administrative health databases (ICES). We included Ontario children aged 1-17 years with a measure of household food insecurity (Household Food Security Survey Module) over the previous 12 months. Our primary outcome was the direct public-payer healthcare costs per child over the same time period (in Canadian dollars, standardized to year 2020). We used gamma-log-transformed generalized estimating equations accounting for the clustering of children to examine this relationship, and adjusted models for important sociodemographic covariates. As a secondary outcome, we examined healthcare usage of specific services and associated costs (e.g. visits to hospitals, surgeries). RESULTS: We found that adjusted healthcare costs were higher in children from food-insecure than from food-secure households ($676.79 [95% CI: $535.26, $855.74] vs. $563.98 [$457.00, $695.99], p = 0.047). Compared with children living in food-secure households, those in insecure households more often accessed hospitals, emergency departments, day surgeries, and home care, and used prescription medications. Children from food-secure households had higher usage of non-physician healthcare (e.g. optometry) and family physician rostering services. CONCLUSION: Even after adjusting for measurable social determinants of health, household food insecurity was associated with higher public-payer health services costs and utilization among children and youth. Efforts to mitigate food insecurity could lessen child healthcare needs, as well as associated costs to our healthcare systems.

RéSUMé: OBJECTIF: Examiner la relation entre l'insécurité alimentaire des ménages et les coûts des soins de santé chez les enfants vivant en Ontario, au Canada. MéTHODE: Nous avons mené une étude populationnelle transversale en utilisant les quatre cycles de l'Enquête sur la santé dans les collectivités canadiennes (2007­2008, 2009­2010, 2011­2012, 2013­2014) liés à des bases de données administratives sur la santé (ICES). Nous avons inclus les enfants ontariens de 1 à 17 ans et un indicateur d'insécurité alimentaire des ménages (le Module d'enquête sur la sécurité alimentaire des ménages) au cours des 12 mois antérieurs. Les coûts directs des soins de santé publics par enfant au cours de cette période (en dollars canadiens de 2020) ont constitué notre résultat principal. Nous avons utilisé des équations d'estimation généralisées transformées par la fonction logarithme gamma tenant compte du regroupement des enfants pour analyser cette relation, et des modèles ajustés pour les covariables sociodémographiques importantes. Comme résultat secondaire, nous avons analysé l'utilisation de certains services de soins de santé (p. ex. les visites dans les hôpitaux, les chirurgies) et les coûts associés. RéSULTATS: Nous avons constaté que les coûts ajustés des soins de santé étaient plus élevés chez les enfants des ménages aux prises avec l'insécurité alimentaire que chez ceux des ménages à l'abri de l'insécurité alimentaire (676,79 $ [IC de 95%: 535,26 $, 855,74 $] contre 563,98 $ [457,00 $, 695,99 $], p = 0,047). Comparativement aux enfants des ménages à l'abri de l'insécurité alimentaire, ceux qui vivaient dans des ménages aux prises avec l'insécurité avaient plus souvent recours aux hôpitaux, aux services des urgences, aux chirurgies d'un jour et aux soins à domicile, et ils prenaient des médicaments sur ordonnance. Les enfants des ménages à l'abri de l'insécurité alimentaire avaient plus souvent recours aux soins de santé non médicaux (p. ex. l'optométrie) et aux services de leur médecin de famille attitré. CONCLUSION: Même après l'apport d'ajustements pour tenir compte des déterminants sociaux de la santé mesurables, l'insécurité alimentaire des ménages était associée à des coûts de soins de santé publics plus élevés et à une plus grande utilisation de ces soins chez les enfants et les jeunes. Des efforts pour atténuer l'insécurité alimentaire pourraient réduire les besoins de soins de santé des enfants, ainsi que les coûts associés pour nos systèmes de soins de santé.

Examining the interactive association of family- and neighborhood-level socio-economic characteristics on children's sleep beyond the associations of residency and neighborhood violence.

OBJECTIVE: To examine the interactive association of neighborhood and family socio-economic characteristics (SEC) on children's sleep. DESIGN: Secondary data analyses were completed on the 2014 Ontario Child Health Study, a cross-sectional sample of 10,802 children aged 4-17. PARTICIPANTS: Children (aged 4-11, 50% male; N = 6264) with available sleep outcome data. METHODS: Multilevel modeling was used to assess the interactive relationship between family- and neighborhood-level poverty in relation to child sleep outcomes (problems falling asleep, problems staying asleep, weekday and weekend time in bed), above the associations of variables known to be related to sleep at the child (ie, child age, sex, internalizing problems, externalizing problems, chronic illness), family (ie, negative parenting behaviors, family structure, parent mental health, years lived in neighborhood, parent education level), and neighborhood levels (ie, neighborhood size, antisocial behavior). RESULTS: Neighborhood poverty (p < .01, ß = -0.001, 95% confidence interval [-0.007, -0.002]) was significantly related to shorter weekday time in bed and the interactive association of family and neighborhood poverty was significantly related to weekend time in bed (p < .05, ß = 0.012, 95% confidence interval [0.004, 0.021]). Children living in low poverty neighborhoods with families of higher SEC backgrounds, and children living in high poverty neighborhoods with families of lower SEC backgrounds had the shortest weekend time in bed (9.7 hours). CONCLUSIONS: There is a compound relationship of family and neighborhood poverty on children's sleep above and beyond family- and child-level risk factors.

Social assistance and trajectories of child mental health problems in Canada: evidence from the National Longitudinal Survey of Children and Youth.

OBJECTIVES: To examine the link between stability and change in social assistance (SA) use and children's mental health trajectories to better understand whether social policies targeted at low-income families might be an effective population-based mechanism for preventing mental health problems among children at risk. METHODS: The National Longitudinal Survey of Children and Youth (N = 8981) is used to classify children into 5 categories based on their family's pattern of SA use from age 4-5 to 10-11: always or never on SA, a single transition on or off SA, or fluctuations on and off SA. Latent growth modelling is used to compare trajectories of emotional and behavioural problems among children with different patterns of SA exposure to their counterparts never on SA over this same time period. RESULTS: Child emotional and behavioural problems are exacerbated over time in accordance with patterns of SA use: chronic SA use (behavioural) and moving onto SA (emotional and behavioural). These differential rates of change result in mental health disparities at age 10-11 that were not present at age 4-5. Children exposed to SA when they were age 4-5 but subsequently moved off continue to demonstrate elevated levels of emotional and behavioural problems at age 10-11. CONCLUSIONS: Successful social policies and interventions will require understanding the specific mechanisms through which SA undermines child mental health and how programs can be modified to reduce its negative consequences.

Area-Level Variation in Children's Unmet Need for Community-Based Mental Health Services: Findings from the 2014 Ontario Child Health Study.

There is limited empirical evidence documenting the magnitude and correlates of area-level variability in unmet need for children's mental health services. Research is needed that identifies area-level characteristics that can inform strategies for reducing unmet need in the population. The study purpose is to: (1) estimate area-level variation in children's unmet need for mental health services (using Service Areas as defined by the Ontario Ministry of Children and Youth Services), and (2) identify area-level service arrangements, and geographic and population characteristics associated with unmet need. Using individual-level general population data, area-level government administrative data and Census data from Ontario, Canada, we use multilevel regression models to analyze unmet need for mental health services among children (level 1) nested within Service Areas (level 2). The study finds that 1.64% of the reliable variance in unmet need for mental health services is attributable to between-area differences. Across areas, we find that Service Areas with more agencies had a lower likelihood of unmet need for mental health services. Compared to other Service Areas, Toronto had much lower likelihood of unmet need compared to the rest of Ontario. Rural areas, areas with unsatisfactory public transport, and areas with higher levels of socio-economic disadvantage had a higher likelihood of unmet need for mental health services. These findings identify challenges in service provision that researchers, policymakers and administrators in children's mental health services need to better understand. Policy implications and potential Service Area strategies that could address equitable access to mental health services are discussed.

Children's Mental Health Need and Expenditures in Ontario: Findings from the 2014 Ontario Child Health Study.

OBJECTIVE: To estimate the alignment between the Ontario Ministry of Children and Youth Services (MCYS) expenditures for children's mental health services and population need, and to quantify the value of adjusting for need in addition to population size in formula-based expenditure allocations. Two need definitions are used: "assessed need," as the presence of a mental disorder, and "perceived need," as the subjective perception of a mental health problem. METHODS: Children's mental health need and service contact estimates (from the 2014 Ontario Child Health Study), expenditure data (from government administrative data), and population counts (from the 2011 Canadian Census) were combined to generate formula-based expenditure allocations based on 1) population size and 2) need (population size adjusted for levels of need). Allocations were compared at the service area and region level and for the 2 need definitions (assessed and perceived). RESULTS: Comparisons were made for 13 of 33 MCYS service areas and all 5 regions. The percentage of MCYS expenditure reallocation needed to achieve an allocation based on assessed need was 25.5% at the service area level and 25.6% at the region level. Based on perceived need, these amounts were 19.4% and 27.2%, respectively. The value of needs-adjustment ranged from 8.0% to 22.7% of total expenditures, depending on the definition of need. CONCLUSION: Making needs adjustments to population counts using population estimates of children's mental health need (assessed or perceived) provides additional value for informing and evaluating allocation decisions. This study provides much-needed and current information about the match between expenditures and children's mental health need.

Patterns of poverty exposure and children's trajectories of externalizing and internalizing behaviors.

Using data from the Child Supplement of the National Longitudinal Survey of Youth, we compare trajectories of externalizing and internalizing behaviors among children exposed to five patterns of poverty from birth to age 14: always or never poor - stable patterns; a single transition into or out of poverty, or repeated fluctuations in and out of poverty - changing patterns. We also examine how low maternal education and single parenthood interact with these poverty exposures to compound their adverse effects. Finally, we compare the magnitude of effects associated with the patterns of poverty exposure, as well as their interactions with low maternal education and single parenthood, on trajectories of externalizing and internalizing behaviors to determine if they are significantly different. Results reveal that initial levels and rates of change in children's trajectories of externalizing and internalizing behaviors are similar across the three changing patterns of poverty exposure, leading us to combine them into a single group representing intermittent poverty. Initial disparities between children who are never poor and their counterparts who are always or intermittently poor are constant over time for internalizing behaviors and grow in magnitude for externalizing behaviors. The cumulative negative effect of poverty exposure over time is stronger for externalizing vs. internalizing behaviors. Low maternal education compounds the adverse effects of persistent poverty, an effect that is similar for externalizing and internalizing behaviors.

Patterns of depressive symptoms and antidepressant use among women survivors of intimate partner violence.

PURPOSE: One of the primary mental health responses of women experiencing intimate partner violence (IPV) is depression, yet little is known about the mental health and antidepressant use of women in the period after leaving an abusive partner. We investigate patterns of antidepressant use and depressive symptoms by various social indicators (parenting status, socioeconomic status, severity of abuse and disclosure of abuse). Second, we examine whether variation in antidepressant use is explained by higher rates of depression diagnoses and/or depressive symptoms, taking these social indicators into consideration. METHODS: We examine data from the Women's Health Effects Study, a community sample of 309 Canadian women who have recently left an abusive partner. RESULTS: Bivariate results reveal that over 80% of women with elevated depressive symptoms are without diagnosis and antidepressant medication. Multivariate analyses show that antidepressant use is predicted by an indicator of economic disadvantage, with women who receive social assistance or disability benefits being more likely to report elevated antidepressant use, controlling for both depressive symptoms and depression diagnoses. CONCLUSIONS: Documenting and explaining depressive symptoms and antidepressant use among IPV survivors provides insight into one of many possible treatment options available to women with depression, and sheds light on potential health disparities among this subgroup of the population.
