A "food insecurity poverty line" to replace the official threshold in Canadian rural and urban settings? A single-person household perspective.

Household food insecurity is associated with both low income and high cost of living, it is a potentially better measure for consumption compared to income. We use data on food insecurity and income from 10 years of the Canadian Community Health Survey (2007-2017) of single-person households (n = 145,044) to estimate the probability of being food insecure at the Canadian poverty thresholds (Market Basket Measure thresholds, or MBMs), and determine the income required to reach that probability in each MBM region, aggregated by province and rural/urban status. A regression model shows the probability of being food insecure at the MBM is approximately 30% which we call the Food Insecurity Poverty Line (FIPL). The income required to meet the FIPL is substantially different from the MBM, sometimes 1.25 times the MBM. This implies that food insecurity is a potential sentinel measure for poverty.

Transitioning to a guaranteed annual income and the impact on activities of daily living in older adults: Evidence from public pensions in Canada using the CLSA.

OBJECTIVE: Statistically model the likelihood of changes in the activities of daily living (ADLs) over time for three groups of older adults: those on a pension at all time periods, those never on a pension, and those who transition onto a public pension. METHODS: Our study used data from the Canadian Longitudinal Study on Aging (CLSA), a large national survey. We used data from baseline (2010-2015) and the first follow-up wave (2015-2018). We used logistic regression to model the likelihood of ADL changes in males and females by pension receipt status, controlling for several potential confounders and allowing for the impact of public pensions to be modified by baseline income. RESULTS: The magnitudes of the estimates indicated that those who transition to a public pension are less likely to report ADL degradation and more likely to report ADL improvement compared to those with no public pension. In the lowest baseline income group, those who transitioned onto a pension at follow-up had a 15% (male) or 11% (female) lower likelihood of reporting degraded ADL scores compared to those not receiving a pension at follow-up. Those who transitioned onto a pension in the lowest income group were more likely to report an improved ADL score at follow-up. CONCLUSION: Our results could provide evidence for the potential health benefits of more comprehensive guaranteed annual income programs beyond the pension program. The penalty of being low-income was mitigated by the stability of the pension income in terms of ADL improvement or degradation.

RéSUMé: OBJECTIF: Modeler statistiquement la probabilité de changements des activités de la vie quotidienne (AVQ) à travers le temps pour trois groupes d'adultes âgés : ceux qui reçoivent une pension tout le temps, ceux qui ne reçoivent jamais une pension, et ceux qui transitionnent à recevoir une pension pendant la période d'étude. MéTHODES: Notre étude a utilisé les données de l'Étude longitudinale canadienne sur le vieillissement (ÉLCV), une grande enquête nationale. On a utilisé les données de base (2010-2015) et de la première vague (2015-2018). On a utilisé une régression logistique pour modeler la probabilité de changement des AVQ dans les hommes et les femmes par statut de réception de pension, en ajustant plusieurs facteurs de confusion potentielles et pour que l'impact de pensions publiques soient modifiées par le revenu de base. RéSULTATS: La magnitude des estimations a indiqué que ceux qui font une transition à une pension publique sont moins probables de signaler une dégradation des AVQ et plus probables de déclarer une amélioration comparés à ceux qui ne reçoivent pas une pension publique. Parmi le groupe de revenu de base le plus bas, ceux qui ont transitionné à recevoir une pension au suivi avaient 15 % (hommes) ou 11 % (femmes) moins de chance de déclarer une évaluation de AVQ dégradée comparé à ceux qui ne recevaient pas une pension au suivi. Ceux qui ont transitionné à recevoir une pension dans le groupe de revenu de base le plus bas étaient plus probables de déclarer une évaluation de AVQ améliorée au suivi. CONCLUSION: Nos résultats pourraient apporter la preuve pour les avantages potentiels des programmes compréhensifs de revenu garanti qui vont plus loin que les pensions publiques. La pénalité de faire partie du groupe de revenu le plus bas est atténuée par la stabilité des revenus de pension en ce qui concerne l'amélioration ou la dégradation des AVQ.

The association between allostatic load and guaranteed annual income using the Canadian Longitudinal Study on Aging: A cross-sectional analysis of the benefits of guaranteed public pensions.

BACKGROUND: Old Age Security (OAS) represents an public policy through which income-related inequalities in health may be improved. The goal of this cross-sectional study was to investigate the health benefits of receiving OAS in financially insecure older Canadians. METHODS: Using data from the Canadian Longitudinal Study on Aging (CLSA) (n=15,691), ordered logistic regression was used to measure associations between financial insecurity and allostatic load. RESULTS: Receiving OAS as highest personal income source appeared to remove the health penalty of being financially insecure. While financial insecurity was associated with worse allostatic load in both males and females not receiving OAS, those receiving OAS as highest personal income source had better allostatic load compared to other financially insecure older adults (ORM: 0.398, 95 % CI: 0.227, 0.696; ORF: 0.677, 95 % CI: 0.483, 0.949). DISCUSSION: While longitudinal data would be needed to draw causal inferences, these results suggest OAS may play a role improving health outcomes and narrowing income-related health inequalities. Such findings may have important implications on older adults, other vulnerable populations, and future directions of Canadian health and public policy.

The effectiveness and decay of public health policy actions on infection-control behaviour in the general public: Evidence from a low-COVID prevalence jurisdiction.

BACKGROUND: Public health policies designed to influence individuals' infection-control behaviour are a tool for governments to help prevent the spread of disease. Findings on the impacts of policies are mixed and there is limited information on the effects of removing restrictions and how policies impact behavioural trends. METHODS: We use low-acuity emergency department visits from 12 hospitals in New Brunswick, Canada, (January 2017 -October 2021) as a proxy for infection-control behaviour and provide insight into the effects of the COVID-19 virus on a population with a low prevalence of cases. Quasi-experimental techniques (event studies) are applied to estimate the magnitude and persistence of effects of specific events (e.g., policy changes), to control for COVID-19 cases and vaccines, and to explore how the effectiveness of policy changes during the pandemic as more policies are introduced. RESULTS: Initial tightening of restrictions on March 11, 2020 reduced low-acuity emergency department visits by around 60% and reached a minimum after 30 days. Relaxing policies on social gatherings and personal services gradually increased low-acuity emergency department visits by approximately 50% after 44 days. No effects were found from policies lifting all restrictions, and reinstating a state of emergency on July 31, 2021, and September 24, 2021. CONCLUSION: These results suggest that policy interventions are less likely to be effective at influencing infection control behaviour with time and more policies introduced, and that tracking and publicly reporting case numbers can influence infection control behaviour.

Exploring the well-being of community pharmacy professionals, turnover intention and patient safety: Time to include operational responsibility.

Background: The COVID-19 pandemic added significant occupational pressures on community pharmacists. The objective of this research project was to investigate the level of distress and burnout among community pharmacy professionals and its association with their retention within their occupation as well as patient safety outcomes. Method: We conducted a cross-sectional study on 722 community pharmacy professionals from all Canadian provinces using an online survey, including scientifically validated measures. The data were analyzed using multiple regression analysis. Results: In Canada, 85% of community pharmacy professionals reported their mental health had suffered since the COVID-19 pandemic. Younger pharmacy professionals and those paid hourly reported a worsening level of mental health and an increasing level of turnover intention. Pharmacists with more dynamic/disrupted work schedules and those working for a large pharmacy chain (more than 25 pharmacies in Canada) reported lower levels of mental health quality. Pharmacy professionals working in pharmacies that are open more than 70 hours a week reported a lower level of patient safety culture. Pharmacists' mental health was the significant predictor of their turnover intention, implying a heightened risk to professional effectiveness and retention. Compassion satisfaction was positively associated with patient safety culture and safety behaviour, while compassion fatigue and secondary traumatic stress were significantly associated with pharmacists' level of risk-taking behaviours. Conclusion: This study emphasized the importance of prioritizing the mental health and well-being of community pharmacy professionals and demonstrated individual and systemic factors predicting the well-being and turnover intention of community pharmacists, as well as patient safety culture within their pharmacy. This research makes a case to consider actions to shift the monitoring focus from community pharmacists (also known as "individual responsibility") to community pharmacies (also known as "operational responsibility") for managing patient safety. Additionally, community pharmacists should be provided with the professional autonomy to affect their working conditions and alleviate the stress that has the potential to negatively affect the delivery of care.

Effect of the COVID-19 pandemic on the socioeconomic composition of emergency department presentations.

OBJECTIVES: This study highlights how socioeconomic trends in the emergency department (ED) for low-acuity visits change with the onset of COVID-19, identifies societal inequities exacerbated by the pandemic, and demonstrates the geographical regions where these inequities occur. METHODS: We accessed 1,285,000 ED visits from 12 different facilities across New Brunswick from January 2017 to October 2020. Using a deprivation index developed by Statistics Canada as a measure of socioeconomic status, and controlling for additional factors, we perform a logistic regression to determine the influence of the COVID-19 pandemic on low-acuity visits of individuals from the most deprived quintile (Q5). We constructed a heat map of New Brunswick to highlight regions of high deprivation. RESULTS: The proportion of Q5 individuals in the ethnocultural composition domain accessing the ED for low-acuity visits increased from 22.91% to 24.72% with the onset of the pandemic. Our logistic regression showed the log odds of being considered Q5 in the ethnocultural composition domain when visiting the ED for a low-acuity reason increased by 6.3% if the visit occurred during the pandemic, and increased by 101.6% if the visit occurred in one of the 3 major regions of New Brunswick. CONCLUSION: Individuals visiting EDs for low-acuity reasons during the COVID-19 pandemic were more likely to be from the most diverse quintile in the ethnocultural domain, and the inequities were concentrated in the most urban regions in New Brunswick. This demonstrates that urban areas are where inequities are disproportionately faced for ethnically diverse individuals and demonstrates where policies could be focused.

RéSUMé: OBJECTIFS: Notre étude montre l'évolution des tendances socioéconomiques des visites aux services d'urgence (SU) pour des affections mineures avec l'apparition de la COVID-19 et indique les iniquités sociétales exacerbées par la pandémie et les régions géographiques où ces iniquités se manifestent. MéTHODE: Nous avons eu accès à 1 285 000 visites aux SU de 12 établissements du Nouveau-Brunswick entre janvier 2017 et octobre 2020. À l'aide d'un indice de défavorisation élaboré par Statistique Canada pour mesurer le statut socioéconomique et après avoir apporté des ajustements pour tenir compte des effets d'autres facteurs, nous avons effectué une analyse de régression logistique pour déterminer l'influence de la pandémie de COVID-19 sur les visites de personnes du quintile le plus défavorisé (Q5) pour des affections mineures. Nous avons construit une carte de densité du Nouveau-Brunswick pour représenter les régions très défavorisées. RéSULTATS: La proportion de personnes du Q5 dans le domaine de la composition ethnoculturelle ayant visité les SU pour des affections mineures est passée de 22,91 % à 24,72 % après le début de la pandémie. Selon notre analyse de régression logistique, la probabilité logarithmique pour une personne ayant visité les SU pour une affection mineure d'être considérée comme faisant partie du Q5 dans le domaine de la composition ethnoculturelle augmentait de 6,3 % si la visite avait eu lieu durant la pandémie, et elle augmentait de 101,6 % si la visite avait eu lieu dans l'une des trois grandes régions du Nouveau-Brunswick. CONCLUSION: Les personnes ayant visité les SU pour des affections mineures durant la pandémie de COVID-19 étaient plus susceptibles d'appartenir au quintile le plus diversifié dans le domaine ethnoculturel, et les iniquités étaient concentrées dans les régions les plus urbaines du Nouveau-Brunswick. L'étude démontre que c'est dans les agglomérations urbaines que les personnes d'origines ethniques diverses font face à des iniquités démesurées, et elle indique où les politiques pourraient être ciblées.

Virtual care and the influence of a pandemic: Necessary policy shifts to drive digital innovation in healthcare.

The potential for virtual healthcare to improve access to primary care services in Canada has long been a topic of discussion; however, implementation has been slow despite growing interest among the public. Non-essential service lockdowns implemented in 2020 in response to the COVID-19 pandemic catalyzed rapid and widespread uptake of virtual healthcare delivery. It is important to consider how to maintain equitable access to virtual care following the pandemic. We conducted a narrative scoping review to understand barriers related to the sustained adoption of virtual primary care delivery in Canada. Barriers at the system, healthcare provider, and patient levels were related to digital health infrastructure, and the regulatory environment governing virtual care provision and remuneration for healthcare professionals. The article identifies areas where policy shifts by health system leaders could sustain the longer-term availability of Canadian virtual care services.

Alcohol access and purchasing behaviour during COVID-19 pandemic restrictions: An exploration of sociodemographic, health and psychosocial correlates in two Canadian provinces.

INTRODUCTION: Alcohol access has changed in Canada during the COVID-19 pandemic. This study compares the use of two novel purchasing modes (via delivery and in excess/stockpiling) to traditional, in-person purchasing to determine if their use is associated with sociodemographic and psychosocial characteristics, perceived COVID-19 health risk or consumption frequency. METHODS: We draw on cross-sectional survey data from 2000 residents of the Canadian provinces of Nova Scotia and New Brunswick, ages 19 years and older that were administered online and by telephone. Associations between purchasing modes and sociodemographic and psychosocial characteristics, perceived COVID-19 health risk or consumption frequency were assessed using logistic regression. RESULTS: About 70% of people who drink purchased in-person, 17% used delivery and 30% purchased in excess/stockpiled. Sociodemographic and psychosocial attributes varied among those at increased odds of using each purchasing mode. Those at higher COVID-19 health risk were at higher odds of getting alcohol delivered. Increased drinking frequency was associated with alcohol delivery and purchasing in excess/stockpiling. DISCUSSION AND CONCLUSIONS: This study highlights the need for increased public health considerations regarding changes to alcohol regulations. Alcohol delivery and purchasing in excess/stockpiling is positively associated with heavier drinking. Drinkers at higher COVID-19 health risk were more likely to purchase online for delivery, which suggests novel purchasing modes may serve a partial public health function.

Changes in alcohol consumption during the COVID-19 pandemic: exploring gender differences and the role of emotional distress. / Modifications de la consommation d'alcool pendant la pandémie de COVID-19 : exploration des différences selon le genre et du rôle de la détresse émotionnelle.

INTRODUCTION: Restrictions to do with the COVID-19 pandemic have had substantial unintended consequences on Canadians' alcohol consumption patterns, including increased emotional distress and its potential impact on alcohol use. This study examines 1) changes in adults' alcohol consumption during the COVID-19 pandemic in New Brunswick and Nova Scotia; 2) whether drinking more frequently during the pandemic is associated with increased feelings of stress, loneliness and hopelessness; and 3) whether gender moderates this relationship. METHODS: Participants were drawn from a cross-sectional survey of 2000 adults. Adjusted multinomial regression models were used to assess the association between drinking frequency and increased feelings of stress, loneliness and hopelessness. Additional analyses were stratified by gender. RESULTS: About 12% of respondents reported drinking more frequently after the start of the COVID-19 pandemic, and 25%-40% reported increased emotional distress. Increased feelings of stress (odds ratio [OR] = 1.99; 95% confidence interval [CI]: 1.35-2.93), loneliness (OR = 1.79; 95% CI: 1.22-2.61) and hopelessness (OR = 1.98; 95% CI: 1.21-3.23) were all associated with drinking more frequently during the pandemic. While women respondents reported higher rates of emotional distress, significant associations with increased drinking frequency were only observed among men in gender-stratified analyses. CONCLUSION: Individuals who report increased feelings of stress, loneliness and hopelessness during the COVID-19 pandemic were more likely to report increased drinking frequency; however, these associations were only significant for men in stratified analyses. Understanding how the pandemic is associated with mental health and drinking may inform alcohol control policies and public health interventions to minimize alcohol-related harm.

CO-aVoID: coronavirus outbreak affecting variability of presentations to a local emergency department.

BACKGROUND: The impact of the COVID-19 pandemic on public health, specifically on patients presenting to the emergency department (ED) with non-COVID-related diseases, remains largely undocumented. OBJECTIVE: This study explored how overall rates of presentations to the emergency department were impacted immediately after the declaration of the COVID-19 pandemic, and specifically how key presenting symptoms representing emergency, standard and low-acuity conditions were impacted. METHODS: A sequential modified Delphi survey and cross-sectional analysis of administrative census data from a tertiary care center in New Brunswick, Canada, were performed. Details of ED presentations for emergency, standard and low-acuity conditions from February 1 to April 30, 2020, were compared to data from previous years. RESULTS: There was a significant decrease in the number of patients visiting the ED with emergency, standard and low-acuity complaints immediately after March 13, 2020, compared to 2019. The proportion of females and males remained similar, with a median age of 48 years in 2020 and 44 years in 2019. Total presentation patterns to the ED (registrations, admissions to hospital and left without being seen numbers) decreased, compared to previous years. CONCLUSIONS: We report a predictable decrease in patient visits to the ED with minor, non-life-threatening conditions during a pandemic. However, we also report a decrease in presentations for emergency and standard conditions. Improved messaging highlighting the need to seek help for "true" emergencies, while providing non-ED options for minor, non-life-threatening conditions, may be helpful under normal circumstances and during future pandemics.

RéSUMé: CONTEXTE: L'impact de la pandémie COVID-19 sur la santé publique, en particulier sur les patients se présentant aux services d'urgence (SU) avec des maladies non liées à la COVID, demeure en grande partie non documenté. OBJECTIF: Cette étude a exploré la façon dont les taux globaux de présentations au service des urgences ont été touchés immédiatement après la déclaration de la pandémie de COVID-19, et plus particulièrement la façon dont les principaux symptômes représentant des conditions d'urgence, standard et de faible acuité ont été touchés. MéTHODES: Une enquête Delphi séquentielle modifiée et une analyse transversale des données du recensement administratif provenant d'un centre de soins tertiaires du Nouveau-Brunswick, au Canada, ont été réalisées. Les détails des présentations du SU pour les conditions d'urgence, standard et de faible acuité du 1er février au 30 avril 2020 ont été comparés aux données des années précédentes. RéSULTATS: Il y a eu une diminution significative du nombre de patients se rendant au service d'urgence avec des plaintes d'urgence, standard et de faible gravité immédiatement après le 13 mars 2020, par rapport à 2019. La proportion de femmes et d'hommes est demeurée semblable, avec un âge médian de 48 ans en 2020 et de 44 ans en 2019. Le nombre total de modèles de présentation à l'urgence (inscriptions, admissions à l'hôpital et nombre laissé sans être vu) a diminué par rapport aux années précédentes. CONCLUSIONS: Nous faisons état d'une diminution prévisible des visites de patients aux urgences pour des affections mineures qui ne mettent pas leur vie en danger pendant une pandémie. Toutefois, nous signalons également une diminution des présentations pour les situations d'urgence et les conditions normales. Des messages améliorés soulignant la nécessité de demander de l'aide pour les urgences « réelles ¼, tout en offrant des options non urgentes pour des conditions mineures et qui ne mettent pas la vie en danger peuvent être utiles dans des circonstances normales et lors de futures pandémies.

An age-independent hospital record-based frailty score correlates with adverse outcomes after heart surgery and increased health care costs.

Background: Globally, an increasing number of vulnerable or frail patients are undergoing cardiac surgery. However, large-scale frailty data are often limited by the need for time-consuming frailty assessments. This study aimed to (1) create a retrospective registry-based frailty score (FS), (2) determine its effect on outcomes and age, and (3) health care costs. Methods: Retrospective data were obtained from the New Brunswick Heart Centre registry for all cardiac surgery patients between 2012 and 2017. A 20-point FS was created using available binary risk variables. The primary outcomes of interest most relevant to vulnerable patients were prolonged hospitalization, failure to be discharged home, and hospitalization bed cost. Composite outcome of prolonged hospitalization (>8 days) and/or non-home discharge were analyzed using multivariate analysis. Results: A total of 3463 patients (mean age, 66 ± 10 years) were included in the final analysis. Tercile-based FSs were: low (0-4; n = 856), medium (5-7; n = 1709), high (≥8; n = 898). In unadjusted data, frail patients were older with more comorbidities. High FS patients had greater risks of prolonged hospitalization (median 7 vs 5 days; P < .001), lower home-discharge rates (51% vs 83%; P < .001), higher 30-day readmission rates (18% vs 10%; P < .001), and increased 30-day mortality rates (≤0.7% [low], >0.7% to ≤1.2% [medium], and >1.2% to 4.8% [high]; P < .001). After statistical adjustment, the FS was an independent predictor of composite outcome (odds ratio, 1.3: 95% CI, 1.26-1.35), and increased hospital bed costs. Conclusions: A registry-based FS can be used to identify vulnerable or frail patients undergoing cardiac surgery and was associated with poor outcomes independent of age. This highlights that although frailty defined by increased vulnerability is often associated with older age, it is not a surrogate for aging, thereby having important implications in reducing health system costs and efforts to provide streamlined care to the most vulnerable.

With great inequality comes great responsibility: the role of government spending on population health in the presence of changing income distributions.

OBJECTIVES: To determine the association between provincial government health and social spending and population health outcomes in Canada, separately for men and women, and account for the potential role of income inequality in modifying the association. METHODS: We used data for nine Canadian provinces, 1981 to 2017. Health outcomes and demographic data are from Statistics Canada; provincial spending data are from provincial public accounts. We model the ratio of social-to-health spending ("the ratio") on potentially avoidable mortality (PAM), life expectancy (LE), potential years of life lost (PYLL), infant mortality, and low birth weight baby incidence. We interact the ratio with the Gini coefficient to allow for income inequality modification. RESULTS: When the Gini coefficient is equal to its average (0.294), the ratio is associated with desirable health outcomes for adult men and women. For example, among women, a 1% increase in the ratio is associated with a 0.04% decrease in PAM, a 0.05% decrease in PYLL, and a 0.002% increase in LE. When the Gini coefficient is 0.02 higher than average, the relationship between the ratio and outcomes is twice as strong as when the Gini is at its average, other than for PAM for women. Infant-related outcomes do not have a statistically significant association with the ratio. CONCLUSION: Overall, outcomes for men and women have similar associations with the ratio. Inequality increases the return to social spending, implying that those who benefit the most from social spending reap higher benefits during periods of higher inequality.

RéSUMé: OBJECTIFS: Déterminer l'association entre les dépenses sociales et de santé du gouvernement provincial et les conditions de santé de la population du Canada, séparément pour hommes et femmes, et expliquer le role que l'inégalité salariale pourrait jouer dans la modification de cette association. MéTHODES: Nous avons utilisé les données pour neuf provinces canadiennes, de 1981 à 2017. Les conditions de santé et les données démographiques parviennent de Statistiques Canada, les données sur les dépenses provinciales parviennent de comptes publiques provinciaux. Nous avons modélisé le rapport de dépenses social-à-santé (« le rapport ¼) sur la mortalité potentiellement évitable (MPE), l'espérance de vie (EV), les années de vie potentielles perdues (AVPP), la mortalité d'enfant et l'incidence d'un poids à la naissance faible. Nous interagissons le rapport avec le coefficient de Gini pour permettre la modification d'inégalité salariale. RéSULTATS: Quand le coefficient de Gini est égal à sa moyenne (0,294), le rapport est associé avec des conditions de santé désirables pour hommes et femmes adultes. Par example, en femmes, une augmentation de 1 % dans le rapport est associé avec une réduction de 0,04 % en MPE, une réduction de 0,05 % en AVPP, et une augmentation de 0,002 % en EV. Quand le coefficient de Gini est 0,02 plus haut que la moyenne, la relation entre le rapport et les résultats est deux fois plus fort que quand le Gini est à sa moyenne, à part la MPE en femmes. Les résultats liés aux nouveau-nés n'ont pas une association statistique significative avec le rapport. CONCLUSION: Globalement, les résultats pour hommes et femmes ont des associations semblables avec le rapport. L'inégalité augmente le retour aux dépenses sociales, insinuant que ceux et celles qui profitent le plus de dépenses sociales récoltent plus de bénéfices pendant des périodes de plus grande inégalité.

Recognizing and responding to women experiencing homelessness with gendered and trauma-informed care.

BACKGROUND: The purpose of this study is to highlight the experiences of women who are often hidden in what we know and understand about homelessness, and to make policy and practice recommendations for women-centred services including adaptations to current housing interventions. METHODS: Three hundred survey interviews were conducted with people experiencing homelessness in Calgary, Alberta, Canada. The survey instrument measured socio-demographics, adverse childhood experiences, mental and physical health, and perceived accessibility to resources. Eighty-one women participants were identified as a subsample to be examined in greater depth. Descriptive statistics and logistic regressions were calculated to provide insight into women respondents' characteristics and experiences of homelessness and how they differed from men's experiences. RESULTS: Women's experiences of homelessness are different from their male counterparts. Women have greater mental health concerns, higher rates of diagnosed mental health issues, suicidal thoughts and attempts, and adverse childhood trauma. The results should not be considered in isolation, as the literature suggests, because they are highly interconnected. CONCLUSION: In order to ensure that women who are less visible in their experiences of homelessness are able to access appropriate services, it is important that service provision is both gender specific and trauma-informed. Current Housing First interventions should be adapted to ensure women's safety is protected and their unique needs are addressed.

Using the ages and stages questionnaire in the general population as a measure for identifying children not at risk of a neurodevelopmental disorder.

BACKGROUND: Early detection of neurodevelopmental disorders (NDDs) enables access to early interventions for children. We assess the Ages and Stages Questionnaire (ASQ)'s ability to identify children with a NDD in population data. METHOD: Children 4 to 5 years old in the National Longitudinal Survey of Children and Youth (NLSCY) from cycles 5 to 8 were included. The sensitivity, specificity, positive and negative predictive values were calculated for the ASQ at 24, 27, 30, 33, 36 and 42 months. Fixed effects regression analyses assessed longitudinal associations between domain scores and child age. RESULTS: Specificity for the ASQ was high with 1SD or 2SD cutoffs, indicating good accuracy in detecting children who will not develop a NDD, however the sensitivity varied over time points and cut-offs. Sensitivity for the 1 SD cutoff at 24 months was above the recommended value of 70% for screening. Differences in ASQ domains scores between children with and without NDD increases with age. CONCLUSIONS: The high specificity and negative predictive values of the ASQ support its use in identifying children who are not at the risk of developing a NDD. The capacity of the ASQ to identify children with a NDD in the general population is limited except for the ASQ-24 months with 1SD and can be used to identify children at risk of NDD.

Effect of provincial spending on social services and health care on health outcomes in Canada: an observational longitudinal study.

BACKGROUND: Escalating health care spending is a concern in Western countries, given the lack of evidence of a direct connection between spending and improvements in health. We aimed to determine the association between spending on health care and social programs and health outcomes in Canada. METHODS: We used retrospective data from Canadian provincial expenditure reports, for the period 1981 to 2011, to model the effects of social and health spending (as a ratio, social/health) on potentially avoidable mortality, infant mortality and life expectancy. We used linear regressions, accounting for provincial fixed effects and time, and controlling for confounding variables at the provincial level. RESULTS: A 1-cent increase in social spending per dollar spent on health was associated with a 0.1% (95% confidence interval [CI] 0.04% to 0.16%) decrease in potentially avoidable mortality and a 0.01% (95% CI 0.01% to 0.02%) increase in life expectancy. The ratio had a statistically nonsignificant relationship with infant mortality (p = 0.2). INTERPRETATION: Population-level health outcomes could benefit from a reallocation of government dollars from health to social spending, even if total government spending were left unchanged. This result is consistent with other findings from Canada and the United States.

Impact of a guaranteed annual income program on Canadian seniors' physical, mental and functional health.

OBJECTIVE: Although there is widespread recognition that poverty is a key determinant of health, there has been less research on the impact of poverty reduction on health. Recent calls for a guaranteed annual income (GAI), defined as regular income provided to citizens by the state regardless of work status, raise questions about the impact, relative to the costs, of such a population health intervention. The objective of this study was to determine the impact of Canadian seniors' benefits (Old Age Security/Guaranteed Income Supplement, analogous to a GAI program) on the self-reported health, self-reported mental health and functional health of age-eligible, low-income seniors. METHODS: We used the 2009-2010 Canadian Community Health Survey to examine unattached adult respondents with an annual income of $20,000 or less, stratified by seniors' benefits/GAI eligibility (55-64 years: ineligible; 65-74 years: eligible). Using regression, we assessed self-reported health, selfreported mental health and functional health as measured by the Health Utilities Index, as outcomes for seniors' benefits/GAI-eligible and -ineligible groups. RESULTS: We found that individuals age-eligible for seniors' benefits/GAI had better health outcomes than recipients of conditional income assistance programs. Eligibility for seniors' benefits/GAI after age 64 was associated with better self-reported health, functional health and self-reported mental health outcomes, and these effects were observed until age 74. CONCLUSION: Using seniors' benefits as an example, a GAI leads to significantly better mental health and improved health overall. These improvements are likely to yield reduced health care costs, which may offset the costs associated with program expansion.

How important are determinants of obesity measured at the individual level for explaining geographic variation in body mass index distributions? Observational evidence from Canada using Quantile Regression and Blinder-Oaxaca Decomposition.

BACKGROUND: Obesity prevalence varies between geographic regions in Canada. The reasons for this variation are unclear but most likely implicate both individual-level and population-level factors. The objective of this study was to examine whether equalising correlates of body mass index (BMI) across these geographic regions could be reasonably expected to reduce differences in BMI distributions between regions. METHODS: Using data from three cycles of the Canadian Community Health Survey (CCHS) 2001, 2003 and 2007 for males and females, we modelled between-region BMI cross-sectionally using quantile regression and Blinder-Oaxaca decomposition of the quantile regression results. RESULTS: We show that while individual-level variables (ie, age, income, education, physical activity level, fruit and vegetable consumption, smoking status, drinking status, family doctor status, rural status, employment in the past 12 months and marital status) may be Caucasian important correlates of BMI within geographic regions, those variables are not capable of explaining variation in BMI between regions. DISCUSSION: Equalisation of common correlates of BMI between regions cannot be reasonably expected to reduce differences in the BMI distributions between regions.
