RESUMO
Background: As Canada continues to experience an opioid crisis, it is important to understand the intersection between the demographic, socioeconomic and service use characteristics of those experiencing opioid overdoses to better inform prevention and treatment programs. Data and methods: The Statistics Canada British Columbia Opioid Overdose Analytical File (BCOOAF) represents people's opioid overdoses between January 2014 and December 2016 (n = 13,318). The BCOOAF contains administrative health data from British Columbia linked to Statistics Canada data, including on health, employment, social assistance and police contacts. Cluster analysis was conducted using the k-prototypes algorithm. Results: The results revealed a six-cluster solution, composed of three groups (A, B and C), each with two distinct clusters (1 and 2). Individuals in Group A were predominantly male, used non-opioid prescription medications and had varying levels of employment. Individuals in Cluster A1 were employed, worked mostly in construction, had high incomes and had a high rate of fatal overdoses, while individuals in Cluster A2 were precariously employed and had varying levels of income. Individuals in Group B were predominantly female; were mostly taking prescription opioids, with about one quarter or less receiving opioid agonist treatment (OAT); mostly had precarious to no employment; and had low to no income. People in Cluster B1 were primarily middle-aged (45 to 65 years) and on social assistance, while people in Cluster B2 were older, more frequently used health services and had no social assistance income. Individuals in Group C were primarily younger males aged 24 to 44 years, with higher prevalence of having experienced multiple overdoses, were medium to high users of health care services, were mostly unemployed and were recipients of social assistance. Most had multiple contacts with police. Those in Cluster C1 predominantly had no documented use of prescription opioid medications, and all had no documented OAT, while all individuals in Cluster C2 were on OAT. Interpretation: The application of machine learning techniques to a multidimensional database enables an intersectional approach to study those experiencing opioid overdoses. The results revealed distinct patient profiles that can be used to better target interventions and treatment.

OBJECTIVES: Mental health and neurocognitive conditions are important causes of hospitalization among immigrants, though patterns may vary by immigrant category, world region of origin, and time since arrival in Canada. This study uses linked administrative data to explore differences in mental health hospitalization rates between immigrants and individuals born in Canada. METHODS: Hospital records from the Discharge Abstract Database and the Ontario Mental Health Reporting System for 2011 to 2017 were linked to the 2016 Longitudinal Immigrant Database and to Statistics Canada's 2011 Canadian Census Health and Environment Cohort. Age-standardized hospitalization rates for mental health-related conditions (ASHR-MHs) were derived for immigrants and the Canadian-born population. ASHR-MHs overall and for leading mental health conditions were compared between immigrants and the Canadian-born population, stratified by sex and selected immigration characteristics. Quebec hospitalization data were not available. RESULTS: Overall, immigrants had lower ASHR-MHs compared to the Canadian-born population. Mood disorders were leading causes of mental health hospitalization for both cohorts. Psychotic, substance-related, and neurocognitive disorders were also leading causes of mental health hospitalization, although there was variation in their relative importance between subgroups. Among immigrants, ASHR-MHs were higher among refugees and lower among economic immigrants, those from East Asia, and those who arrived in Canada most recently. CONCLUSION: Differences in hospitalization rates among immigrants from various immigration streams and world regions, particularly for specific types of mental health conditions, highlight the importance of future research that incorporates both inpatient and outpatient mental health services to further understand these relationships.
RéSUMé: OBJECTIFS: Les problèmes de santé mentale et les troubles neurocognitifs sont des causes importantes d'hospitalisation chez les immigrants, bien que les tendances puissent varier selon la catégorie d'immigrants, la région d'origine mondiale et le temps écoulé depuis l'arrivée au Canada. Cette étude utilise des données administratives couplées afin d'explorer les différences dans les taux d'hospitalisation en santé mentale entre les immigrants et les personnes nées au Canada. MéTHODES: Les dossiers hospitaliers de la Base de données sur les congés des patients et du Système d'information ontarien sur la santé mentale de 2011 à 2017 ont été couplés à la Base de données longitudinales sur l'immigration de 2016 et aux cohortes santé et environnement du Recensement canadien de 2011 de Statistique Canada. Les taux d'hospitalisation normalisés selon l'âge pour les problèmes de santé mentale (THNA-SM) ont été comparés entre les immigrants et la population née au Canada, stratifiés selon le sexe et certaines caractéristiques d'immigration. Les données sur les hospitalisations au Québec n'étaient pas disponibles. RéSULTATS: Dans l'ensemble, les immigrants avaient des THNA-SM plus faibles que la population née au Canada. Les troubles de l'humeur étaient les principales causes d'hospitalisation en santé mentale pour les deux cohortes. Les troubles psychotiques, liés aux substances et neurocognitifs étaient également les principales causes d'hospitalisation en santé mentale, bien que leur importance relative varie entre les sous-groupes. Chez les immigrants, les THNA-SM étaient plus élevés chez les réfugiés et plus faibles chez les immigrants économiques, ceux de l'Asie de l'Est et ceux qui sont arrivés au Canada plus récemment. CONCLUSION: Les différences dans les taux d'hospitalisation chez les immigrants des divers groupes d'immigration et régions du monde, plus particulièrement pour certains types de problèmes de santé mentale, soulignent l'importance de recherches futures qui intègrent les services de santé mentale aux patients hospitalisés ainsi qu'aux patients externes afin de mieux comprendre ces relations.

Using the OncoSim All Cancers Model, we estimated the annual cancer incidence, mortality and cancer management costs in Canada from 2020 to 2040. Incidence for each cancer type was estimated from logistic regression analyses of the Canadian Cancer Registry (1992-2017), with province/territory, sex, five-year age groups and year as covariates. Deaths were estimated by sex and tumour site for cancers diagnosed between 2000 and 2017 (deaths to the end of 2017). The total cost of a cancer type was the sum of costs for individuals across four phases of cancer care. The projections presented in this study were generated based on a simulation of 32 million cases. The OncoSim All Cancers Model projects a 40% increase in the overall number of incident cancer cases from 2020 to 2040. The number of the four most commonly diagnosed cancers in Canada (breast, colorectal, lung, and prostate) are projected to increase annually. The overall number of cancer deaths is projected to increase by 44% from 2020 to 2040. More cancer deaths are projected in males than in females. The age-standardized mortality rate is expected to remain relatively stable over time. Overall cancer management costs are projected to increase from $20.6B in 2020 to $31.4B in 2040. Due mainly to an aging population and population growth in Canada, we estimate that cancer incidence, mortality and cancer management costs will increase considerably between 2020 and 2040. These results highlight the importance of planning for increasing investment and capacity in cancer control.

Background: Estimates of polypharmacy have primarily been derived from prescription claims, and less is known about the use of non-prescription medications (alone or in combination with prescription medications) across the frailty spectrum or by sex. Our objectives were to estimate the prevalence of polypharmacy (total, prescription, non-prescription, and concurrent prescription and non-prescription) overall, and by frailty, sex and broad age group. Data: Canadian Health Measures Survey, Cycle 5, 2016 to 2017. Methods: Among Canadians aged 40 to 79 years, all prescription and non-prescription medications used in the month prior to the survey were documented. Polypharmacy was defined as using five or more medications total (prescription and non-prescription), prescription only and non-prescription only. Concurrent prescription and non-prescription use was defined as two or more and three or more of each. Frailty was defined using a 31-item frailty index (FI) and categorized as non-frail (FI ≤ 0.1) and pre-frail or frail (FI > 0.1). Survey-weighted descriptive statistics were calculated overall and age standardized. Results: We analyzed 2,039 respondents, representing 16,638,026 Canadians (mean age of 56.9 years; 51% women). Overall, 52.4% (95% confidence interval [CI] = 47.3 to 57.4) were defined as pre-frail or frail. Age-standardized estimates of total polypharmacy, prescription polypharmacy and concurrent prescription and non-prescription medication use were significantly higher among pre-frail or frail versus non-frail adults (e.g., total polypharmacy: 64.1% versus 31.8%, respectively). Polypharmacy with non-prescription medications was common overall (20.5% [95% CI = 16.1 to 25.8]) and greater among women, but did not differ significantly by frailty. Interpretation: Polypharmacy and concurrent prescription and non-prescription medication use were common among Canadian adults, especially those who were pre-frail or frail. Our findings highlight the importance of considering non-prescribed medications when measuring the exposure to medications and the potential risk for adverse outcomes.

BACKGROUND: The burden of out-of-pocket costs among cancer patients/survivors in Canada is not well understood. The objective of this study was to examine the health-related out-of-pocket cost burden experienced by households with a cancer patient/survivor compared to those without, examine the components of health-related costs and determine who experiences a greater burden. DATA AND METHODS: This study used a data linkage between the Survey of Household Spending and the Canadian Cancer Registry to identify households with a cancer patient/survivor (cases) and those without (controls). The out-of-pocket burden (out-of-pocket costs measured relative to household income) and mean costs were described and regression analyses examined the characteristics associated with the household out-of-pocket burden and annual out-of-pocket costs. RESULTS: The health-related out-of-pocket cost burden and annual costs measured in households with a cancer patient/survivor were 3.08% (95% CI: 2.55-3.62%) and CAD 1600 (95% CI: 1456-1759), respectively, compared to a burden of 2.84% (95% CI: 2.31-3.38) and annual costs of CAD 1511 (95% CI: 1377-1659) measured in control households, respectively. Households with a colorectal cancer patient/survivor had a significantly higher out-of-pocket burden compared to controls (mean difference: 1.0%, 95% CI: 0.18, 0.46). Among both cases and controls, the lowest income quintile households experienced the highest health-related out-of-pocket cost burden. INTERPRETATION: Within a universal health care system, it is still relevant to monitor health-related out-of-pocket spending that is not covered by existing insurance mechanisms; however, this is not routinely assessed in Canada. We demonstrate the feasibility of measuring such costs in households with a cancer patient/survivor using routinely collected data. While the burden and annual health-related out-of-pocket costs of households with a cancer patient/survivor were not significantly higher than control households in this study, the routine measurement of out-of-pocket costs in Canada could be systemized, providing a novel, system-level, equity-informed performance indicator, which is relevant for monitoring inequities in the burden of out-of-pocket costs.

BACKGROUND: OncoSim-Breast is a Canadian breast cancer simulation model to evaluate breast cancer interventions. This paper aims to describe the OncoSim-Breast model and how well it reproduces observed breast cancer trends. METHODS: The OncoSim-Breast model simulates the onset, growth, and spread of invasive and ductal carcinoma in situ tumours. It combines Canadian cancer incidence, mortality, screening program, and cost data to project population-level outcomes. Users can change the model input to answer specific questions. Here, we compared its projections with observed data. First, we compared the model's projected breast cancer trends with the observed data in the Canadian Cancer Registry and from Vital Statistics. Next, we replicated a screening trial to compare the model's projections with the trial's observed screening effects. RESULTS: OncoSim-Breast's projected incidence, mortality, and stage distribution of breast cancer were close to the observed data in the Canadian Cancer Registry and from Vital Statistics. OncoSim-Breast also reproduced the breast cancer screening effects observed in the UK Age trial. CONCLUSIONS: OncoSim-Breast's ability to reproduce the observed population-level breast cancer trends and the screening effects in a randomized trial increases the confidence of using its results to inform policy decisions related to early detection of breast cancer.

BACKGROUND: As Canadian immigration levels increase, knowledge concerning immigrant health becomes increasingly important for health system policy and planning. This study compares the rate of all-cause hospitalization among immigrants with that of their Canadian-born counterparts. DATA AND METHODS: Using records from the Discharge Abstract Database (2004/2005 to 2016/2017) and the Ontario Mental Health Reporting System (2006/2007 to 2017/2018) linked to the 2016 Longitudinal Immigration Database, this study compared the age-standardized hospitalization rates (ASHRs) among immigrants with those of the Canadian-born population; the latter were obtained from a linkage based on the 2011 National Household Survey. Comparisons were made at the International Classification of Diseases chapter level by immigrant landing year, admission category and world region of birth. Quebec data were not available. RESULTS: Overall, ASHRs among immigrants were lower than for the Canadian-born population. Immigrants in the economic class had the lowest ASHR, followed by those in the family class and among refugees. After pregnancy was excluded, leading hospitalization causes were similar for immigrants and the Canadian-born population, where top causes included digestive system and circulatory diseases, injuries, and cancer. In male and female immigrants, the ASHRs were lowest among those from East Asia. By landing year, males arriving earlier had the highest ASHR compared with the most recent arrivals. When pregnancy was excluded and while the differential in ASHRs among females by landing year remained, the magnitude was smaller. INTERPRETATION: These results corroborate those from previous studies suggesting a healthy immigrant effect, but also reveal heterogeneity in ASHRs within the immigrant population. They provide a baseline for comparison of health status between populations, which enables further monitoring and informs health-system policy and planning.

BACKGROUND: Following the 2016 opioid overdose emergency declaration in British Columbia (B.C.), provincial stakeholders collaborated to link data that resulted in the B.C. Provincial Overdose Cohort. This database provides information about people who have experienced opioid overdoses to inform policy and intervention developments. Subsequently, Statistics Canada likewise constructed a cohort and integrated federal data to broaden the scope of the B.C. initiative. This provided federally sourced information about people's circumstances that was not otherwise available. DATA AND METHODS: The Statistics Canada British Columbia Opioid Overdose Analytical File further characterizes the socioeconomic circumstances of 13,318 people who experienced illicit drug toxicity deaths and non-fatal opioid overdoses in B.C. between January 1, 2014, and December 31, 2016. Statistics Canada linked federal data on immigration, employment, the justice system and social assistance receipt in the year of, and prior to, people's first overdose. RESULTS: During the observation period, most people (78%) had one overdose episode, rather than several. Seven percent were immigrants or temporary residents, 41% of whom arrived in Canada more than 20 years before their index overdose. Half (49.6%) had not received social assistance, and one-third (33.8%) were employed-primarily within construction (21% of those employed)-in the year prior to their index overdose. Most employed people (65.5%) experienced periods of unemployment within five years prior to their index overdose. Employment was more prevalent among people who experienced illicit-drug toxicity death (36.1%). About 60% of people had not had any formal police contact within the two years prior to the index overdose. DISCUSSION: This project demonstrated further added value to existing data by using this linkage approach and aligned with strategies underway by BC public health partners to provide cross-sectoral evidence to inform efforts to prevent and manage opioid overdoses.

BACKGROUND: Reliance on the use of opioids to manage pain has increased over time, as have opioid-related morbidity and deaths. In 2018, 12.7% of Canadians reported having used opioid pain relief medications (OPRMs) in the previous year. Among these people, 9.6% had engaged in problematic use that could cause harm to their health. Though socioeconomic characteristics associated with opioid-related harms have previously been reported, population-level evidence based on administrative health data lacks important behavioural and psychosocial information. This analysis extends previous research by using modelling to report factors related to the problematic use of OPRMs for the household population aged 15 and older in Canada. DATA AND METHODS: This analysis uses responses to the 2018 Canadian Community Health Survey to identify factors that are significantly associated, after adjustment using multivariate logistic regression models, with elevated odds of problematic use of OPRMs. RESULTS: The fully adjusted model confirmed that being male, being younger (ages 20 to 24), having fair or poor mental health, having unmet needs for help with mental or emotional health or substance problems, being a smoker, or being unattached and living with others were significantly related to problematic OPRM use. INTERPRETATION: Subjective perceptions significantly related to problematic OPRM use, independent of socioeconomic circumstances, were examined in this study. While previous research based on administrative health data has contributed much to knowledge about factors associated with opioid harms, modelled results revealed that self-reported experiential factors also warrant consideration as they are significantly associated with problematic use. Having fair or poor mental health, having unmet perceived needs for help, and being unattached in terms of household arrangement relationship were related to problematic use of OPRMs, even after adjustment for socioeconomic and other health covariates. This study suggests risk profiles that could be used to inform health care providers, and strategies to support safe pain management.

BACKGROUND: Palliative care (PC) has been shown to improve outcomes for individuals at the end of life. Despite this, many Canadians do not receive PC prior to death. The present study examines the receipt of inpatient PC and its association with location of death, as well as with admission to intensive care units (ICUs) and use of alternate level of care (ALC) beds in hospital in the last 30 days of life. DATA AND METHODS: The study sample is a retrospective cohort of adult Canadians (aged 19 and older) who died between April 1, 2010, and December 31, 2014. Deaths were ascertained from the Canadian Vital Statistics Database and linked to hospitalizations records in the Discharge Abstract Database to identify the receipt of inpatient PC. RESULTS: More than half (57.7%) of Canadian adults died in hospital, with only 12.6% receiving any inpatient PC in the year prior to death, and 1.7% receiving a preterminal PC designation (i.e., PC initiated prior to the last 30 days of life). In the adjusted analyses, receipt of any inpatient PC was associated with a higher likelihood of death in hospital but lower odds of ICU admission. Pre-terminal PC was associated with lower odds of death in hospital, ICU admission and ALC bed use. DISCUSSION: This study offers new insights into the association between inpatient PC and outcomes at the end of life among Canadians. Future studies could expand on these observations to further understanding of the role of inpatient PC in the end-of-life experience for different populations in Canada.

INTRODUCTION: The objective of our study was to present model-based estimates and projections on current and future health and economic impacts of cerebral palsy in Canada over a 20-year time horizon (2011-2031). METHODS: We used Statistics Canada's Population Health Model (POHEM)-Neurological to simulate individuals' disease states, risk factors and health determinants and to describe and project health outcomes, including disease incidence, prevalence, life expectancy, health-adjusted life expectancy, health-related quality of life and health care costs over the life cycle of Canadians. Cerebral palsy cases were identified from British Columbia's health administrative data sources. A population-based cohort was then used to generate the incidence and mortality rates, enabling the projection of future incidence and mortality rates. A utility-based measure (Health Utilities Index Mark 3) was also included in the model to reflect various states of functional health to allow projections of health-related quality of life. Finally, we estimated caregiving parameters and health care costs from Canadian national surveys and health administrative data and included them as model parameters to assess the health and economic impact of cerebral palsy. RESULTS: Although the overall crude incidence rate of cerebral palsy is projected to remain stable, newly diagnosed cases of cerebral palsy will rise from approximately 1800 in 2011 to nearly 2200 in 2031. In addition, the number of people with the condition is expected to increase from more than 75 000 in 2011 to more than 94 000 in 2031. Direct health care costs in constant 2010 Canadian dollars were about $11 700 for children with cerebral palsy aged 1-4 years versus about $600 for those without the condition. In addition, people with cerebral palsy tend to have longer periods in poorer health-related quality of life. CONCLUSION: Individuals with cerebral palsy will continue to face challenges related to an ongoing need for specialized medical care and a rising need for supportive services. Our study offers important insights into future costs and impacts associated with cerebral palsy and provides valuable information that could be used to develop targeted health programs and strategies for Canadians living with this condition.

BACKGROUND: Caregivers of children with health problems (CHPs; usually mothers) experience more physical and psychological health problems than those of children without health problems (non-CHPs). Primarily cross-sectional and survey-driven, this literature has not yet explored whether these health differences existed before the birth of the CHPs, or are exacerbated postbirth. METHODS: Using linked administrative health data on all mother-child dyads for children born in the year 2000 in British Columbia, Canada, we examined maternal health before, during, and after the birth of CHPs, and compared it between mothers of CHPs and non-CHPs with piecewise growth curve modeling. RESULTS: Compared with mothers of non-CHPs, mothers of CHPs had more physician visits (8.09 vs. 11.07), more medication types (1.81 vs. 2.60), and were more likely to be diagnosed with selected health conditions (30.9% vs. 42.5%) 4 years before the birth of the child. Over the 7-year postbirth period, the health of the 2 groups of mothers further diverged: while mothers of CHPs showed increases on physician visits and types of medication, mothers of non-CHPs did not experience any changes in physician visits and had less steep increases for types of medication. CONCLUSIONS: Health issues associated with having a child with a health problem may begin well before the birth of the child, but also appear to be exacerbated postbirth. The health challenges of caregivers of CHPs may be multifactorial, involving both preexisting conditions and the stresses associated with caring for a child with health problems.

INTRODUCTION: Caregivers of children with health problems experience poorer health than the caregivers of healthy children. To date, population-based studies on this issue have primarily used survey data. OBJECTIVES: We demonstrate that administrative health data may be used to study these issues, and explore how non-categorical indicators of child health in administrative data can enable population-level study of caregiver health. METHODS: Dyads from Population Data British Columbia (BC) databases, encompassing nearly all mothers in BC with children aged 6-10 years in 2006, were grouped using a non-categorical definition based on diagnoses and service use. Regression models examined whether four maternal health outcomes varied according to indicators of child health. RESULTS: 162,847 mother-child dyads were grouped according to the following indicators: Child High Service Use (18%) vs. Not (82%), Diagnosis of Major and/or Chronic Condition (12%) vs. Not (88%), and Both High Service Use and Diagnosis (5%) vs. Neither (75%). For all maternal health and service use outcomes (number of physician visits, chronic condition, mood or anxiety disorder, hospitalization), differences were demonstrated by child health indicators. CONCLUSIONS: Mothers of children with health problems had poorer health themselves, as indicated by administrative data groupings. This work not only demonstrates the research potential of using routinely collected health administrative data to study caregiver and child health, but also the importance of addressing maternal health when treating children with health problems.
RESUMO
Hospitalizations due to opioid poisonings are increasing. While considerable information is available on the demographic and geographic distribution of opioid-related events, national data on the social and economic circumstances of those experiencing these events are limited. This study uses data from the National Household Survey (2011) linked to the Discharge Abstract Database (2011 to 2016) to provide the first national-level estimates of the socio-economic characteristics of individuals experiencing opioid-related hospitalizations. Results reveal elevated hospitalization rates among people who have lower levels of income and education, are unemployed or out of the labour force, identify as Indigenous, live in lone-parent households, and spend more than 50% of their household income on housing. Understanding the circumstances of individuals who experienced adverse opioid events will help inform policies addressing potential determinants.

BACKGROUND: The aging of the Canadian population has increased attention on the future need for nursing home beds. Although current projections rely primarily on age and sex, other factors also contribute to the need for long-term care. This study seeks to identify additional factors to age and sex that contribute to Canadians transitioning from living at home to living in a seniors' residence or nursing home. DATA AND METHODS: As part of a larger record linkage project, three cycles of the Canadian Community Health Survey (CCHS) were linked to the 2011 Census of Population: Cycle 3.1 (2005/2006), Cycle 4.1 (2007/2008), and CCHS-Healthy Aging (2008/2009). The sample was limited to successfully linked CCHS respondents who were aged 60 years or older as of Census Day 2011 (May 10, 2011; n=81,411). Sex-specific generalized multinomial logistic regression models were conducted to examine the association between each respondent's characteristics and dwelling location (private dwelling, private dwelling with additional family, nursing home, or seniors' residence) on Census Day. RESULTS: On Census Day, 1.4% of the study sample were living in a nursing home, 1.2% in a seniors' residence, 7.1% in a private dwelling with additional family, and 90.3% in a private dwelling. Women were more likely than men to be living in a nursing home (1.8% of women vs. 0.9% of men) or seniors' residence (1.7% of women vs. 0.7% of men). Regression models showed that, aside from age, there were increased odds of living in a nursing home or seniors' residence among individuals who lost their spouse or who were not married, who did not own their dwelling, who had poor self-rated health, or who had been diagnosed with dementia. The association of other factors with dwelling place differed according to sex and type of dwelling. DISCUSSION: Although age is strongly associated with living in a nursing home or seniors' residence, other demographic and health factors affect the likelihood of an individual transitioning to an institutional dwelling. Such factors could be considered when planning for the future housing and care needs of the Canadian population.

BACKGROUND: Health-related quality of life (HRQoL) measures are of interest because they can be used to describe health of populations and represent a broader health outcome for population health analyses than mortality rates or life expectancy. The most widely used measure of HRQoL for deriving estimates of health-adjusted life expectancy is the Health Utilities Index Mark 3 (HUI3). The HUI3 is available in most national surveys administered by Statistics Canada, and has been used as part of a microsimulation model to examine the impact of neurological conditions over the life course. Persons receiving home care and nursing home services are often not well-represented in these surveys; however, interRAI assessment instruments are now used as part of normal clinical practice in these settings for nine Canadian provinces/territories. Building on previous research that developed a HUI2 crosswalk for the interRAI assessments, the present study examined a new interRAI HRQoL index crosswalked to the HUI3. METHODS: interRAI and survey data were used to examine the distributional properties of global and domain-specific interRAI HRQoL and HUI3 index scores, respectively. Three populations were considered: well-elderly persons not receiving home care, home care clients and nursing home residents. RESULTS: The mean HUI3 and interRAI HRQoL index global scores declined from independent healthy older persons to home care clients, followed by nursing home residents. For the home care and nursing home populations, the interRAI HRQoL global estimates tended to be lower than HUI3 global scores obtained from survey respondents. While there were some statistically significant age, sex and diagnostic group differences in global scores and within attributes, the most notable differences were between populations from different care settings. DISCUSSION: The present study provides strong evidence for the validity of the interRAI HRQoL based on comparisons of distributional properties with those obtained with survey data based on the HUI3. The results demonstrate the importance of admission criteria for home care and nursing home settings, where function plays a more important role than demographic or diagnostic criteria. The interRAI HRQoL has a distinct advantage because it is gathered as part of normal clinical practice in care settings where interRAI instruments are mandatory and are used to assess all eligible persons in those sectors. In particular, those with severe cognitive and functional impairments (who tend to be under-represented in survey data) will be evaluated using the interRAI tools. Future research should build on this work by providing direct, person-level comparisons of interRAI HRQoL index and HUI3 scores, as well as longitudinal analyses to examine responsiveness to change.

BACKGROUND: The increasing prevalence of overweight and obesity has necessitated the development of body mass index (BMI) projection models such as the POpulation HEalth Model (POHEM). This study describes the POHEM-BMI model, a microsimulation tool that can be used to support evidence-based health policy making for obesity reduction. DATA AND METHODS: The National Population Health Survey, the Canadian Community Health Survey (CCHS), and the Canadian Health Measures Survey (CHMS) were used to develop and validate a predictive model of BMI for adults and childhood BMI history. Models were incorporated into POHEM and used to transition BMI over time in a fully dynamic simulated Canadian population. RESULTS: POHEM-BMI projections of self-reported and measured adult BMI and childhood BMI history agree well with CCHS and CHMS validation estimates. Among men and women, average BMI is projected to increase by more than one BMI unit between 2001 and 2030. Projections of self-reported BMI show that 59% of the adult population will be overweight or obese by 2030; projections of measured BMI show that the percentage will be 66%. INTERPRETATION: Using empirically developed BMI prediction models for adults and childhood BMI history integrated into the POHEM framework, validated projections of BMI for the Canadian population can be produced. Projections of BMI trends could have important applications in tracking the prevalence of related diseases, and in planning and comparing intervention strategies.

BACKGROUND: Respiratory diseases are among the leading causes of acute care hospitalization for First Nations people. Poor housing conditions are associated with respiratory disorders and may be related to the likelihood of hospitalization. This analysis examines whether First Nations identity is associated with higher odds of hospitalization for respiratory conditions relative to non-Aboriginal persons, and whether such differences in hospitalization rates remain after consideration of housing conditions. DATA AND METHODS: Data from the 2006 Census linked to the Discharge Abstract Database were used to analyze differences in hospitalization for respiratory tract infections and asthma between First Nations and non-Aboriginal people when housing conditions were taken into account. RESULTS: Rural on-reserve First Nations people were more likely than non-Aboriginal people to be hospitalized for a respiratory tract infection (1.5% versus 0.5%) or for asthma (0.2% versus 0.1%). For respiratory tract infection hospitalizations, adjustment for housing conditions, household income and residential location reduced differences, but the odds remained nearly three times higher for on-reserve First Nations people (OR = 2.83; CI: 2.69 to 2.99) and two times higher for off-reserve First Nations people (OR = 2.03; CI: 1.87 to 2.21), compared with the non-Aboriginal cohort. For asthma hospitalizations, adjustment for household income reduced the odds more than did adjustment for housing conditions. Even with full adjustment, the odds of asthma hospitalization relative to non-Aboriginal people remained significantly higher for First Nations people. INTERPRETATION: First Nations people are significantly more likely than non-Aboriginal people to be hospitalized for respiratory tract infections and asthma, even when housing conditions, household income and residential location are taken into account. While housing conditions are associated with such hospitalizations, household income may be more important.

INTRODUCTION: The objective of our study was to present model-based estimates and projections on current and future health and economic impacts of multiple sclerosis (MS) in Canada over a 20-year time horizon (2011-2031). METHODS: Using Statistics Canada's Population Health Microsimulation Model (POHEM) framework, specifically the population-based longitudinal, microsimulation model named POHEM-Neurological, we identified people with MS from health administrative data sources and derived incidence and mortality rate parameters from a British Columbia population-based cohort for future MS incidence and mortality projections. We also included a utility-based measure (Health Utilities Index Mark 3) reflecting states of functional health to allow projections of health-related quality of life. Finally, we estimated caregiving parameters and health care costs from Canadian national surveys and health administrative data and included them as model parameters to assess the health and economic impact of the neurological conditions. RESULTS: The number of incident MS cases is expected to rise slightly from 4051 cases in 2011 to 4794 cases per 100 000 population in 2031, and the number of Canadians affected by MS will increase from 98 385 in 2011 to 133 635 in 2031. The total per capita health care cost (excluding out-of-pocket expenses) for adults aged 20 and older in 2011 was about $16 800 for individuals with MS, and approximately $2500 for individuals without a neurological condition. Thus, after accounting for additional expenditures due to MS (excluding out-of-pocket expenses), total annual health sector costs for MS are expected to reach $2.0 billion by 2031. As well, the average out-of-pocket expenditure for people with MS was around $1300 annually throughout the projection period. CONCLUSION: MS is associated with a significant economic burden on society, since it usually affects young adults during prime career- and family-building years. Canada has a particularly high prevalence of MS, so research such as the present study is essential to provide a better understanding of the current and future negative impacts of MS on the Canadian population, so that health care system policymakers can best plan how to meet the needs of patients who are affected by MS. These findings also suggest that identifying strategies to prevent MS and more effectively treat the disease are needed to mitigate these future impacts.
INTRODUCTION: L'objectif de notre étude est de présenter des estimations et des projections des répercussions épidémiologiques et économiques de la sclérose en plaques (SP) au Canada sur 20 ans (2011-2031). MÉTHODOLOGIE: Nous avons utilisé un modèle de microsimulation de la santé de la population (POHEM) de Statistique Canada, plus précisément le modèle longitudinal de microsimulation démographique appelé POHEM - Maladies neurologiques. Nous avons sélectionné les personnes atteintes de SP à partir de sources de données administratives sur la santé et dérivé les paramètres liés à l'incidence de la maladie et au taux de décès d'une étude de cohorte de la Colombie-Britannique afin de prévoir quels seront l'incidence de la SP et son taux de décès. Nous avons également inclus une mesure reposant sur l'utilité (Health Utilities Index Mark 3) qui rend compte des états de santé fonctionnelle afin de réaliser des projections sur la qualité de vie liée à la santé. Enfin, nous avons estimé les paramètres de prestation de soins et de coûts des soins de santé à partir de sondages nationaux du Canada et de données administratives sur la santé et nous les avons inclus comme paramètres dans le modèle visant à évaluer les répercussions économiques et sur la santé des maladies neurologiques. RÉSULTATS: On anticipe une légère augmentation du nombre de cas incidents de SP, passant de 4 051 cas pour 100 000 personnes en 2011 à 4 974 en 2031. Le nombre de Canadiens touchés par la SP passera ainsi de 98 385 en 2001 à 133 635 en 2031. Le coût total des soins de santé par personne (à l'exception des dépenses directes) pour les adultes de 20 ans et plus atteints de SP en 2011 était d'environ 16 800 $, contre un peu moins de 2500 $ pour ceux ne souffrant d'aucune affection neurologique. Si on comptabilise les dépenses supplémentaires liées à la SP (à l'exception des dépenses directes), les coûts totaux annuels de la SP pour le secteur de la santé devraient donc atteindre deux milliards de dollars d'ici 2031. Par ailleurs, les dépenses directes moyennes des personnes atteintes de SP seront d'environ 1300 $ par année tout au long de la période de projection. CONCLUSION: La SP est associée à un important fardeau économique pour la société car elle touche surtout de jeunes adultes à un moment fondateur pour leur vie professionnelle et leur vie familiale. Sa prévalence étant particulièrement élevée au Canada, des recherches comme la nôtre sont essentielles afin de mieux comprendre les répercussions actuelles et futures de la SP sur la population canadienne, afin que les décideurs du réseau de la santé puissent mieux planifier les besoins en soins de santé pour les malades qui en sont atteints. Selon ces résultats, des stratégies pour prévenir la SP et la traiter plus efficacement sont essentielles pour en atténuer les futures répercussions.

BACKGROUND: Cadmium has been inconsistently related to blood pressure and hypertension. The present study seeks to clarify the relationship between cadmium levels found in blood and urine, blood pressure and hypertension in a large sample of adults. METHODS: The study sample included participants ages 20 through 79 from multiple cycles of the Canadian Health Measures Survey (2007 through 2013) with measured blood cadmium (n=10,099) and urinary cadmium (n=6988). Linear regression models examined the association between natural logarithm transformed cadmium levels and blood pressure (separate models for systolic and diastolic blood pressure) after controlling for known covariates. Logistic regression models were used to examine the association between cadmium and hypertension. Models were run separately by sex, smoking status, and body mass index category. RESULTS: Men had higher mean systolic (114.8 vs. 110.8mmHg, p<0.01) and diastolic (74.0 vs. 69.6mmHg, p<0.01) blood pressure compared to women. Although, geometric mean blood (0.46 vs. 0.38µg/L, p<0.01) and creatinine-adjusted standardized urinary cadmium levels (0.48 vs. 0.38µg/L, p<0.01) were higher among those with hypertension, these differences were no longer significant after adjustment for age, sex and smoking status. In overall regression models, increases in blood cadmium were associated with increased systolic (0.70mmHg, 95% confidence interval [CI]=0.25-1.16, p<0.01) and diastolic blood pressure (0.74mmHg, 95% CI=0.30-1.19, p<0.01). The associations between urinary cadmium, blood pressure and hypertension were not significant in overall models. Model stratification revealed significant and negative associations between urinary cadmium and hypertension among current smokers (OR=0.61, 95% CI=0.44-0.85, p<0.01), particularly female current smokers (OR=0.52, 95% CI=0.32-0.85, p=0.01). CONCLUSION: This study provides evidence of a significant association between cadmium levels, blood pressure and hypertension. However, the significance and direction of this association differs by sex, smoking status, and body mass index category.
