Background: This study described the differences in the hospitalization rates of First Nations children and youth living on and off reserve, Inuit children and youth living in Inuit Nunangat (excluding Nunavik), and Métis children and youth, relative to non-Indigenous children and youth and examined rate changes across 2006 and 2011.

Data and methods: The 2006 and the 2011 Canadian Census Health and Environment Cohorts provided five years of hospital records that Statistics Canada linked to peoples' self-reported Indigenous identity as recorded on the census. Causes of hospitalizations were based on the most responsible diagnosis coded according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada, aggregated by chapter code. Age-standardized hospitalization rates (ASHRs) were calculated per 100,000 population. Rate ratios (RRs) were reported for each Indigenous group relative to non-Indigenous children and youth.

Results: For the 2006 and the 2011 cohorts, ASHRs were generally higher among Indigenous children and youth than among non-Indigenous children and youth. For some health conditions, hospitalization patterns also varied across the two time periods within the given Indigenous groups. Among children, leading elevated RRs occurred for diseases of the respiratory system, the digestive system and injuries. Elevated mental health-related RRs were observed among all Indigenous groups for both cohort years of youth. Significant increases in mental health-related ASHRs were observed in 2011 compared with 2006 among all youth groups, except for Inuit youth living in Inuit Nunangat, possibly due in part to data limitations. Among Indigenous youth, elevated RRs were observed for pregnancy, childbirth and the puerperium, and for injuries. For all youth (except Inuit), childbirth-related ASHRs decreased in 2011 compared with 2006.

Interpretation: Findings align with previously observed hospitalization disparities between Indigenous and non-Indigenous children and youth. These data enabled the tracking of changes over time to partly address national information gaps about population health outcomes for children and youth, namely hospitalization.

Introduction: This study's objective was to examine sociodemographic disparities in COVID-19 vaccine uptake and vaccination intent in the Canadian provinces by identifying factors associated with vaccine uptake in seniors prioritized for vaccination at the time of the survey and vaccination intent in all adults.

Data and methods: A cross-sectional survey of Canadian adults was conducted in all provinces from mid-April to mid-May 2021. In addition to sociodemographic characteristics, respondents (n=10,678) provided information on their COVID-19 vaccination status or their intent to get vaccinated. Logistic regression models were fitted using sociodemographic factors as explanatory variables and vaccination status (unvaccinated vs at least one dose) or vaccination intent (unlikely versus likely or already vaccinated) as outcomes. To account for vaccine prioritization groups, multiple regression models were adjusted for province of residence, age, Indigenous identity and health care worker status.

Results: Seniors with a lower household income (less than $60,000) and those living in smaller communities (fewer than 100,000 inhabitants) had higher odds of being unvaccinated. Among Canadian adults, the odds of being unlikely to get vaccinated were higher for males (adjusted odds ratio [AOR] 1.3), individuals younger than 60 (AOR between 3.3 and 5.1), non-health care workers (AOR 3.3), those with less than a high school education (AOR 3.4) or a household income of less than $30,000 (AOR 2.7) and individuals who do not identify as South Asian, Chinese, Black, Filipino, Arab, Latin American, Southeast Asian, West Asian, Korean or Japanese (AOR 1.7).

Interpretation: COVID-19 vaccine uptake (80%) and vaccination intent (95%) were high among Canadians; however, relative disparities were observed among specific groups. Continued efforts targeted toward these groups are essential in reducing potential inequity in access or service provision.

Introduction: Eye care is important, but it is not always promoted as much as other aspects of health. A visit to an eye care professional is made when need, stimulus, access and availability exist.

Data and methods: Data from cycles 5 and 6 (2016 to 2019) of the Canadian Health Measures Survey were used. Analyzed variables were related to sociodemographic characteristics, general health, behaviour and eye health. Estimates were obtained using survey weights, and 95% confidence intervals were obtained with bootstrap weights.

Results: From 2016 to 2019, 75% of people diagnosed with diabetes visited an eye care professional during the previous year. For people not diagnosed with diabetes, the rate varied, at 57% for those aged 6 to 18 years, 40% for those aged 19 to 64, and 63% for those aged 65 to 79. For those aged 6 to 64, wearing glasses and having access to a family doctor were the main factors associated with a visit to an eye care professional in the previous year. For those aged 65 to 79, cataracts, sex, marital status and self-perceived quality of life were the most significant factors.

Interpretation: Although wearing glasses or having eye diseases was associated with a visit to an eye care professional, this study revealed additional emerging associated factors: access to a family doctor for people aged 6 to 64, and an excellent or very good self-perceived quality of life for those aged 65 to 79.

Background: Most socio-epidemiological studies on diabetes incidence, prevalence, or hospitalization focus on individual-level risk factors. This population-based cohort study sought to advance understanding on the associations of contextual characteristics and risk of diabetes-related avoidable hospitalization (DRAH) among at-risk Canadians.

Data and methods: A national cohort was compiled from the 2013/2014 Canadian Community Health Survey, representing 5.1 million adults aged 35 years and older, reporting having been diagnosed with diabetes, hypertension, or heart disease. Their information was linked longitudinally to hospitalization data from the 2013/14 to 2017/18 Discharge Abstract Database as well as to measures of geographic variability from the Material and Social Deprivation Index and the Index of Remoteness. Cox regression models were used to examine associations between the contextual indices and first occurrence of a DRAH.

Results: Residents in the most rural and remote communities were 50% more likely (hazard ratio (HR): 1.51, 95% confidence interval (95% CI): 1.26 to 1.80) to experience a DRAH than those in the most urbanized and accessible communities, and residents in the most socially deprived areas were significantly more likely (HR: 1.44, 95% CI: 1.26 to 1.65) to be hospitalized than those in the most socially privileged areas, controlling for individuals' sociodemographic characteristics and health behaviours. Neighbourhood material deprivation did not exercise a statistically significant influence on hospitalization risk after adjusting for the other residential characteristics.

Interpretation: There is a clear and significant gradient in diabetes-related hospitalization risk among Canadians with an underlying cardiometabolic condition by degree of residential remoteness and of neighbourhood social deprivation, independently of individual characteristics and despite Canada's universal healthcare system.

Background: Individuals with chronic conditions have higher levels of health care usage and may be at higher risk of more severe outcomes from COVID-19. Therefore, they may have experienced greater difficulty accessing health care during the pandemic because of restrictions on health care services.

Data and methods: Data from the Survey on Access to Health Care and Pharmaceuticals During the Pandemic were used to estimate the proportion of individuals in Canada, with and without chronic conditions, who experienced difficulties accessing health care services during the pandemic. Multivariate analyses examined associations between demographic, socioeconomic and health characteristics and the likelihood of experiencing difficulties accessing health care during the pandemic.

Results: Nearly one-third (32.0%) of individuals who self-reported having one or more chronic conditions and 24.2% of those who reported no conditions had one or more medical appointments cancelled, rescheduled or delayed because of COVID-19. Smaller proportions of individuals with (19.5%) and without (16.8%) chronic conditions delayed contacting a medical professional because of fear of exposure to COVID-19 in health care settings. Individuals who were younger or had a disability were also more likely than older individuals or those without a disability, respectively, to have had a medical appointment cancelled, rescheduled or delayed because of the pandemic. Women, immigrants, and individuals with multiple chronic conditions were more likely than their counterparts (men, Canadian-born individuals, and individuals with no chronic conditions, respectively) to have delayed contacting a medical professional because of fear of exposure to COVID-19.

Interpretation: Individuals with chronic conditions were more likely than those with no chronic conditions to have experienced difficulties accessing health care during the pandemic. Consequently, these individiuals may be at greater risk of experiencing health challenges in the future.

Background: Data on meeting the Canadian 24-Hour Movement Guidelines for adults (24-H Guidelines) and associations with health indicators by body mass index (BMI) class are needed to support public health surveillance. The aim of this study was to describe the proportion of Canadian adults meeting individual and various combinations of the 24-H Guidelines by BMI class and their association with health indicators.

Data and methods: Data from the cross-sectional Canadian Health Measures Survey cycles 1 to 4 (2007 to 2015, n = 10,515 adults aged 18 to 79 years) were used. Daily time spent in moderate-to-vigorous physical activity (MVPA) and sedentary behaviour were assessed using accelerometry. Sleep duration, recreational screen time, chronic conditions, sociodemographic characteristics, and general and mental health were self-reported. The BMI, waist circumference, blood pressure and aerobic fitness were directly measured. Respondents were classified as meeting the 24-H Guidelines when: • the MVPA was 150 minutes per week or more; • sedentary time was nine hours or less per day; • recreational screen time was three hours or less per day; • sleep duration was seven to nine hours per day for individuals aged 18 to 64 years or seven to eight hours per day for individuals aged 65 years and older.

Results: Significantly fewer adults with overweight (6.1%) or class I (4.3%) and class II or III (3.9%) obesity met all three 24-H Guidelines compared with those with normal weight (9.5%). Meeting all three or two recommendations of the 24-H Guidelines was generally associated with a lower waist circumference, higher aerobic physical fitness and self-perceived general health regardless of BMI class.

Interpretation: Canadian adults living with overweight and obesity are less likely to meet the 24-H Guidelines. Most of the benefits associated with meeting the 24-H Guidelines are observed regardless of BMI status.

Introduction: The Statistics Canada Biobank (Biobank) is a valuable source of nationally representative health information. It contains biospecimens collected from the Canadian Health Measures Survey (CHMS) and the Canadian COVID-19 Antibody and Health Survey (CCAHS). Both surveys are voluntary and aim to collect a variety of important health information from Canadians to create nationally representative estimates. This information is collected through questionnaires, physical measures, and self-administered sample collection. Biospecimens collected as part of the CHMS and CCAHS from consenting participants include whole blood, plasma, serum, urine, DNA samples, and dried blood spots. These samples are stored as part of the Biobank for future health research. Canadian researchers can apply to the Biobank program to use this nationally representative source of biospecimens. Results obtained from their research can also be combined with a wide variety of health and lifestyle information collected as part of the CHMS and CCAHS, making the Biobank a rich source of health-related information that can fill data gaps on the health concerns that are important to Canadians. This data resource profile provides an overview of the Biobank to inform researchers and data users about the program and how it can be used as a resource for the advancement of health-related research.
