Behavioural interventions delivered through interactive social media for health behaviour change, health outcomes, and health equity in the adult population.

BACKGROUND: Social networking platforms offer a wide reach for public health interventions allowing communication with broad audiences using tools that are generally free and straightforward to use and may be combined with other components, such as public health policies. We define interactive social media as activities, practices, or behaviours among communities of people who have gathered online to interactively share information, knowledge, and opinions. OBJECTIVES: We aimed to assess the effectiveness of interactive social media interventions, in which adults are able to communicate directly with each other, on changing health behaviours, body functions, psychological health, well-being, and adverse effects. Our secondary objective was to assess the effects of these interventions on the health of populations who experience health inequity as defined by PROGRESS-Plus. We assessed whether there is evidence about PROGRESS-Plus populations being included in studies and whether results are analysed across any of these characteristics. SEARCH METHODS: We searched CENTRAL, CINAHL, Embase, MEDLINE (including trial registries) and PsycINFO. We used Google, Web of Science, and relevant web sites to identify additional studies and searched reference lists of included studies. We searched for published and unpublished studies from 2001 until June 1, 2020. We did not limit results by language. SELECTION CRITERIA: We included randomised controlled trials (RCTs), controlled before-and-after (CBAs) and interrupted time series studies (ITSs). We included studies in which the intervention website, app, or social media platform described a goal of changing a health behaviour, or included a behaviour change technique. The social media intervention had to be delivered to adults via a commonly-used social media platform or one that mimicked a commonly-used platform. We included studies comparing an interactive social media intervention alone or as a component of a multi-component intervention with either a non-interactive social media control or an active but less-interactive social media comparator (e.g. a moderated versus an unmoderated discussion group). Our main outcomes were health behaviours (e.g. physical activity), body function outcomes (e.g. blood glucose), psychological health outcomes (e.g. depression), well-being, and adverse events. Our secondary outcomes were process outcomes important for behaviour change and included knowledge, attitudes, intention and motivation, perceived susceptibility, self-efficacy, and social support. DATA COLLECTION AND ANALYSIS: We used a pre-tested data extraction form and collected data independently, in duplicate. Because we aimed to assess broad outcomes, we extracted only one outcome per main and secondary outcome categories prioritised by those that were the primary outcome as reported by the study authors, used in a sample size calculation, and patient-important. MAIN RESULTS: We included 88 studies (871,378 participants), of which 84 were RCTs, three were CBAs and one was an ITS. The majority of the studies were conducted in the USA (54%). In total, 86% were conducted in high-income countries and the remaining 14% in upper middle-income countries. The most commonly used social media platform was Facebook (39%) with few studies utilising other platforms such as WeChat, Twitter, WhatsApp, and Google Hangouts. Many studies (48%) used web-based communities or apps that mimic functions of these well-known social media platforms. We compared studies assessing interactive social media interventions with non-interactive social media interventions, which included paper-based or in-person interventions or no intervention. We only reported the RCT results in our 'Summary of findings' table. We found a range of effects on health behaviours, such as breastfeeding, condom use, diet quality, medication adherence, medical screening and testing, physical activity, tobacco use, and vaccination. For example, these interventions may increase physical activity and medical screening tests but there was little to no effect for other health behaviours, such as improved diet or reduced tobacco use (20,139 participants in 54 RCTs). For body function outcomes, interactive social media interventions may result in small but important positive effects, such as a small but important positive effect on weight loss and a small but important reduction in resting heart rate (4521 participants in 30 RCTs). Interactive social media may improve overall well-being (standardised mean difference (SMD) 0.46, 95% confidence interval (CI) 0.14 to 0.79, moderate effect, low-certainty evidence) demonstrated by an increase of 3.77 points on a general well-being scale (from 1.15 to 6.48 points higher) where scores range from 14 to 70 (3792 participants in 16 studies). We found no difference in effect on psychological outcomes (depression and distress) representing a difference of 0.1 points on a standard scale in which scores range from 0 to 63 points (SMD -0.01, 95% CI -0.14 to 0.12, low-certainty evidence, 2070 participants in 12 RCTs). We also compared studies assessing interactive social media interventions with those with an active but less interactive social media control (11 studies). Four RCTs (1523 participants) that reported on physical activity found an improvement demonstrated by an increase of 28 minutes of moderate-to-vigorous physical activity per week (from 10 to 47 minutes more, SMD 0.35, 95% CI 0.12 to 0.59, small effect, very low-certainty evidence). Two studies found little to no difference in well-being for those in the intervention and control groups (SMD 0.02, 95% CI -0.08 to 0.13, small effect, low-certainty evidence), demonstrated by a mean change of 0.4 points on a scale with a range of 0 to 100. Adverse events related to the social media component of the interventions, such as privacy issues, were not reported in any of our included studies. We were unable to conduct planned subgroup analyses related to health equity as only four studies reported relevant data. AUTHORS' CONCLUSIONS: This review combined data for a variety of outcomes and found that social media interventions that aim to increase physical activity may be effective and social media interventions may improve well-being. While we assessed many other outcomes, there were too few studies to compare or, where there were studies, the evidence was uncertain. None of our included studies reported adverse effects related to the social media component of the intervention. Future studies should assess adverse events related to the interactive social media component and should report on population characteristics to increase our understanding of the potential effect of these interventions on reducing health inequities.

Monitoring gender equity in mental health in a low-, middle-, and high-income country in the Americas.

OBJECTIVE: Gender disparities in mental health highlight the need to include gender equity measures when planning, implementing, and evaluating mental health programs at national, state or provincial, and municipal levels. This study aimed to identify, select, and assess the feasibility of comparing gender-sensitive mental health indicators in a low- (Peru), middle- (Colombia), and high- (Canada) income country. METHODS: The indicators were selected by a multidisciplinary group of experts who used criteria and a framework proposed by the World Health Organization. Data from national, population-based databases from each country were used to measure the indicators. RESULTS: Seven indicators (12-month prevalence of the following: depression, psychological distress, generalized anxiety disorder, suicide attempts, alcohol dependence, mental health service use, and psychological impairment) were feasible for measurement in at least two countries. Only five indicators were comparable between two countries, and only one was comparable among all countries (suicide attempts). The indicators that showed the greatest inequities between men and women were depression, anxiety, suicide attempts, use of mental health services, and alcohol dependence. Female-to-male ratios for prevalence of mental illness ranged from .1 to 2.3, and ratios for service use ranged from 1.3 to 1.9. Significant trends were found when the indicators were considered by age, education, marital status, and income. CONCLUSIONS: Some of these indicators can be used to identify populations most vulnerable to gender inequities in mental health. The results from this study may provide useful information to program planners who aim to implement, improve, and monitor national mental health strategies that reduce gender inequities under different national conditions.

Migration and health in Canada: health in the global village.

BACKGROUND: Immigration has been and remains an important force shaping Canadian demography and identity. Health characteristics associated with the movement of large numbers of people have current and future implications for migrants, health practitioners and health systems. We aimed to identify demographics and health status data for migrant populations in Canada. METHODS: We systematically searched Ovid MEDLINE (1996-2009) and other relevant web-based databases to examine immigrant selection processes, demographic statistics, health status from population studies and health service implications associated with migration to Canada. Studies and data were selected based on relevance, use of recent data and quality. RESULTS: Currently, immigration represents two-thirds of Canada's population growth, and immigrants make up more than 20% of the nation's population. Both of these metrics are expected to increase. In general, newly arriving immigrants are healthier than the Canadian population, but over time there is a decline in this healthy immigrant effect. Immigrants and children born to new immigrants represent growing cohorts; in some metropolitan regions of Canada, they represent the majority of the patient population. Access to health services and health conditions of some migrant populations differ from patterns among Canadian-born patients, and these disparities have implications for preventive care and provision of health services. INTERPRETATION: Because the health characteristics of some migrant populations vary according to their origin and experience, improved understanding of the scope and nature of the immigration process will help practitioners who will be increasingly involved in the care of immigrant populations, including prevention, early detection of disease and treatment.

A meta-analysis of randomized control trials of home-based secondary prevention programs for coronary artery disease.

BACKGROUND: A variety of different types of secondary prevention programs for coronary heart disease (CHD) exist. Home-based programs have become more common and may be more accessible or preferable to some patients. This review compared the benefits and costs of home-based programs with usual care and cardiac rehabilitation. METHODS: A meta-analysis following a systematic search of 19 databases, existing reviews, and references was designed. Studies evaluated home-based interventions that addressed more than one main CHD risk factor using a randomized trial with a usual care or cardiac rehabilitation comparison group with data extractable for CHD patients only and reported in English as a full article or thesis. RESULTS: Thirty-nine articles reporting 36 trials were reviewed. Compared with usual care, home-based interventions significantly improved quality of life [weighted mean difference: 0.23; 95% confidence interval (95% CI): 0.02-0.45], systolic blood pressure (weighted mean difference: -4.36 mmHg; 95% CI: -6.50 to -2.22), smoking cessation (difference in proportion: 14%; 95% CI: 0.02-0.26), total cholesterol (standardized mean difference: -0.33; 95% CI: -0.57 to -0.08), and depression (standardized mean difference: -0.33; 95% CI: -0.59 to -0.07). Effect sizes were small to moderate and trials were of low-to-moderate quality. Comparisons with cardiac rehabilitation could not be made because of the small number of trials and high levels of heterogeneity. CONCLUSION: Home-based secondary prevention programs for CHD are an effective and relatively low-cost complement to hospital-based cardiac rehabilitation and should be considered for stable patients less likely to access or adhere to hospital-based services.

Socioeconomic status and cardiovascular disease: risks and implications for care.

Socioeconomic status (SES) refers to an individual's social position relative to other members of a society. Low SES is associated with large increases in cardiovascular disease (CVD) risk in men and women. The inverse association between SES and CVD risk in high-income countries is the result of the high prevalence and compounding effects of multiple behavioral and psychosocial risk factors in people of low SES. However, strong and consistent evidence shows that parental SES, childhood and early-life factors, and inequalities in health services also contribute to elevated CVD risk in people of low SES who live in high-income countries. In addition, place of residence can affect CVD risk, although the data on the influence of wealth distribution and work-related factors are inconsistent. Studies on the effects of SES on CVD risk in low-income and middle-income countries is scarce, but evidence is emerging that the increasing wealth of these countries is beginning to lead to replication of the patterns seen in high-income countries. Clinicians should address the association between SES and CVD by incorporating SES into CVD risk calculations and screening tools, reducing behavioral and psychosocial risk factors via effective and equitable primary and secondary prevention, undertaking health equity audits to assess inequalities in care provision and outcomes, and by use of multidisciplinary teams to address risk factors over the life course.

Migration to western industrialised countries and perinatal health: a systematic review.

Influxes of migrant women of childbearing age to receiving countries have made their perinatal health status a key priority for many governments. The international research collaboration Reproductive Outcomes And Migration (ROAM) reviewed published studies to assess whether migrants in western industrialised countries have consistently poorer perinatal health than receiving-country women. A systematic review of literature from Medline, Health Star, Embase and PsychInfo from 1995 to 2008 included studies of migrant women/infants related to pregnancy or birth. Studies were excluded if there was no cross-border movement or comparison group or if the receiving country was not western and industrialised. Studies were assessed for quality, analysed descriptively and meta-analysed when possible. We identified 133 reports (>20,000,000 migrants), only 23 of which could be meta-analysed. Migrants were described primarily by geographic origin; other relevant aspects (e.g., time in country, language fluency) were rarely studied. Migrants' results for preterm birth, low birthweight and health-promoting behaviour were as good or better as those for receiving-country women in >or=50% of all studies. Meta-analyses found that Asian, North African and sub-Saharan African migrants were at greater risk of feto-infant mortality than 'majority' receiving populations, and Asian and sub-Saharan African migrants at greater risk of preterm birth. The migration literature is extensive, but the heterogeneity of the study designs and definitions of migrants limits the conclusions that can be drawn. Research that uses clear, specific migrant definitions, adjusts for relevant risk factors and includes other aspects of migrant experience is needed to confirm and understand these associations.

A review of the cost of cardiovascular disease.

In Canada, 74,255 deaths (33% of all deaths) in 2003 were due to cardio-vascular disease (CVD). As one of the most costly diseases, CVD represents a major economic burden on health care systems. The purpose of the present study was to review the literature on the economic costs of CVD in Canada and other developed countries (United States, Europe and Australia) published from 1998 to 2006, with a focus on Canada. Of 1656 screened titles and abstracts, 34 articles were reviewed including six Canadian studies and 17 American studies. While considerable variation was observed among studies, all studies indicated that the costs of treating CVD-related conditions are significant, outlining a convincing case for CVD prevention programs.

Individual, social, environmental, and physical environmental correlates with physical activity among Canadians: a cross-sectional study.

BACKGROUND: The identification of various individual, social and physical environmental factors affecting physical activity (PA) behavior in Canada can help in the development of more tailored intervention strategies for promoting higher PA levels in Canada. This study examined the influences of various individual, social and physical environmental factors on PA participation by gender, age and socioeconomic status, using data from the 2002 nationwide survey of the Physical Activity Monitor. METHODS: In 2002, 5,167 Canadians aged 15-79 years, selected by random-digit dialling from household-based telephone exchanges, completed a telephone survey. The short version of the International Physical Activity Questionnaire was used to collect information on total physical activity. The effects of socio-economical status, self-rated health, self-efficacy, intention, perceived barriers to PA, health benefits of PA, social support, and facility availability on PA level were examined by multiple logistic regression analyses. RESULTS: Self-efficacy and intention were the strongest correlates and had the greatest effect on PA. Family income, self-rated health and perceived barriers were also consistently associated with PA. The effects of the perceived health benefits, education and family income were more salient to older people, whereas the influence of education was more important to women and the influence of perceived barriers was more salient to women and younger people. Facility availability was more strongly associated with PA among people with a university degree than among people with a lower education level. However, social support was not significantly related to PA in any subgroup. CONCLUSION: This study suggests that PA promotion strategies should be tailored to enhance people's confidence to engage in PA, motivate people to be more active, educate people on PA's health benefits and reduce barriers, as well as target different factors for men and women and for differing socio-economic and demographic groups.

Rural-urban disparities in health: how does Canada fare and how does Canada compare with Australia?

OBJECTIVE: To analyse rural-urban and intra-rural disparities in health status in Canada and to compare Canada with Australia with respect to such disparities. DESIGN: Four indicators were used to show rural-urban and intra-rural differences in health status: (i) mortality due to circulatory diseases, (ii) mortality due to cancer, (iii) injury-related mortality; and (iv) all-cause mortality. Rural was disaggregated into finer categories based on degree of remoteness, using the Metropolitan Influence Zone classification in Canada and the Accessibility/Remoteness Index of Australia. Comparisons were made using age-standardised mortality rates and standardised mortality ratios. PARTICIPANTS: Rural and urban populations of Canada and Australia. RESULTS: The study confirmed previous findings that rural Canadians tended to have poorer health status than their urban counterparts. However, when rural was disaggregated into finer categories, different health status patterns emerged. Although the most rural areas tended to have the worst health status, the least rural areas generally enjoyed good health. The Canada-Australia comparisons revealed convergence and divergence. CONCLUSIONS: The similarities between Canada and Australia show that rural-urban disparities in health status are not limited to a particular country. For several causes of death, whereas the mortality risks in Rural 1 areas in Canada are significantly lower than in urban areas, the opposite is true in Australia, suggesting that although there are some common patterns across the two countries in relation to rural-urban health status disparities, nation-specific uniqueness is to be expected.

Immunization coverage among young children of urban immigrant mothers: findings from a universal health care system.

OBJECTIVE: To investigate access to effective primary health care services in children of new immigrants to Canada by assessing immunization coverage at age 2. METHODS: We used multiple linked administrative data sets to analyze primary health service use and immunizations of children born between July 1, 1997, and June 30, 1998, in Ontario, Canada. These children were linked via their mothers' records to a federal Landed Immigrant Database. We used logistic regression to assess the effect on up-to-date (UTD) status at age 2 of having an immigrant mother, controlling for patient and physician characteristics. We examined the relationship of region of origin, period of immigration, and refugee status on coverage. RESULTS: The study population comprised 98 123 children, of whom 66.5% had complete immunization coverage. Children of immigrant mothers were more likely to be UTD (adjusted odds ratio, 1.15; 95% confidence interval, 1.10, 1.19) than children born to nonimmigrant mothers. Within the group of children of immigrant mothers, those whose mothers were refugees had the lowest rates of coverage (66.6%), but when adjusting for maternal age, sex, neighborhood income quintile, and health services characteristics, region of origin was the most important predictor of coverage. Those from the region of Southeast and Northeast Asia were most likely to be UTD (odds ratio, 1.63; 95% confidence interval, 1.46, 1.81). Period of immigration was not associated with coverage. CONCLUSIONS: Contrary to expectations, immigrant mothers are accessing immunizations at least as well as nonimmigrants for their young children in Ontario. There is variation by region of origin and socioeconomic status. Universal access to care reduces disparities in immunization coverage, but overall rates are too low.

Non-communicable disease and injury-related mortality in rural and urban places of residence: a comparison between Canada and Australia.

BACKGROUND: Few published studies looking at cross-national comparisons of rural-urban health status are available. As a first step towards addressing the lack of information on how rural populations in Canada compare with rural populations elsewhere in the world, this paper examines and contrasts Canadian mortality risks of selected diseases in rural and urban areas with those of Australia. METHODS: Age-standardized mortality ratios for selected causes of deaths were calculated at the national level and broken down into place of residence categories using country-specific definitions of rurality (Metropolitan Influence Zones in Canada and the Australian Standard Geographical Classification [ASGC] Remoteness in Australia). RESULTS: Patterns of rural-urban mortality risk were mostly similar in both countries. However, depending on the causes of death examined, important differences were found. Mortality from motor vehicle accidents, suicide and a few cancer sites showed similar urban-rural gradients in both Canada and Australia. Notable differences were found for diabetes, all cancers combined, as well as lung and colorectal cancer. Rural Australians were at higher risk of dying from these diseases than their urban counterparts, whereas rural Canadians were at lower risk than urban Canadians. DISCUSSION: Overall, the patterns that have emerged from this comparison of Canadian and Australian mortality risks suggest that health status disparities between rural and urban populations are not limited to a specific country or region of the world. However, there are also important differences between the two countries, as the geographic mortality patterns varied according to sex and according to disease category. This analysis is an initial step in promoting discussion of rural health in an international context.

Trends in mortality from ischemic heart disease in Canada, 1986-2000.

This study examined trends in ischemic heart disease (IHD) mortality rates in Canada from 1986 to 2000, including analyses at the county level. The study population comprised Canadians aged 35 and over. Age-standardized mortality rates (ASMRs) were computed. Linear regression and Poisson regression were used to calculate average annual percentage change (AAPC) by age, sex, county and province. A substantial decrease in mortality rates was observed in those aged 35 and over for both sexes; the AAPC indicated a decline of 3.44 percent for males and 3.42 percent for females. The ASMRs were plotted for three time periods; the rates increased with each successive age group and decreased with each consecutive time period for both sexes. A significant decline in the IHD mortality rate was found in 47.2 percent and 46.9 percent of the counties among males and females, respectively; those counties had a statistically significant lower prevalence of daily smoking in both genders, and obese in females only. Only two counties showed a significant increase in the ASMRs of IHD in males and females, respectively. Enhanced prevention and control strategies should be considered to address IHD in countries where more modest decreases (or no decrease at all) in IHD mortality have been observed.

Disparities in mortality patterns among Canadian immigrants and refugees, 1980-1998: results of a national cohort study.

This study examines mortality patterns among Canadian immigrants, including both refugees and non-refugees, 1980-1998. Records of a stratified random sample of Canadian immigrants landing between 1980-1990 (N = 369,936) were probabilistically linked to mortality data (1980-1998). Mortality rates among immigrants were compared to those of the general Canadian population, stratifying by age, sex, immigration category, region of birth and time in Canada. Multivariate analysis examined mortality risks for various immigrant subgroups. Although immigrants presented lower all-cause mortality than the general Canadian population (SMR between 0.34 and 0.58), some cause-specific mortality rates were elevated among immigrants, including mortality from stroke, diabetes, infectious diseases (AIDS and hepatitis among certain subgroups), and certain cancers (liver and nasopharynx). Mortality rates differed by region of birth, and were higher among refugees than other immigrants. These results support the need to consider the heterogeneity of immigrant populations and vulnerable subgroups when developing targeted interventions.

Mortality: life and health expectancy of Canadian women.

HEALTH ISSUE: The sex differences in mortality, life expectancy, and, to a lesser extent, health expectancy, are well recognized in Canada and internationally. However, the factors explaining these differences between women and men are not well understood. This chapter explores the contribution of various causes of death (such as preventable, and sex-specific deaths) on these differences between women and men. KEY FINDINGS: "External" preventable causes of death (e.g. smoking-related, injuries, etc.) were responsible for a large portion of the sex gap in mortality and life expectancy. When excluding these causes from the calculations, the sex gap in life expectancies were largely reduced, decreasing from approximately 5.5 years (life expectancy being 81.4, years in women, and 75.9 years in men) to approximately 2.2 years (84.9 in women and 82.7 in men). Sex gaps in corresponding health expectancies entirely disappeared when these preventable causes of death were excluded. Moreover, a larger death burden was observed among women than men for sex-specific causes of death (eg. excess breast cancer, gynaecological cancers, maternal mortality). Significant disparities were also observed in the mortality rates of various subgroups of women by geographic regions of Canada. DATA GAPS AND RECOMMENDATIONS: These results indicate that women do not appear to have a large biological survival advantage but, rather, are at lower risk of preventable deaths. They also provide additional information needed for the development of policies aimed at reducing disparities in life and health expectancies in Canada and other developed countries.

Morbidity Experiences and Disability Among Canadian Women.

HEALTH ISSUE: Women are more frequently affected by chronic conditions and disability than men. Although some of these sex differences have been in part attributed to biological susceptibility, social determinants of health and other factors, these gaps have not been fully explained in the current literature. This chapter presents comparisons of hospitalization rates, and the prevalence of chronic conditions and physical disability between Canadian women and men and between various subgroups of women, adjusting for selected risk factors. The Canadian Hospital Morbidity Database (2000-2001) and Canadian Community Health Survey (2000-2001) were used to examine inpatient hospital morbidity, prevalence of chronic conditions and disability. KEY FINDINGS: Hospitalization rates were 20% higher among women than men. This was due to the large number of hospitalizations for pregnancies and childbirth. When "normal" deliveries were excluded, hospitalization rates remained higher among women. Women had slightly lower rates of hospitalizations for ambulatory-care sensitive conditions than men. Prevalence of activity limitation (mild and severe) was higher among women than men, and differences remained after adjusting for age, chronic conditions, socio-economic status, and smoking. Women who reported a disability were less likely than men to be in a partnered relationship, have less tangible social support, and have lower income and employment rates. DATA GAPS AND RECOMMENDATIONS: The impact of morbidity and disability on Canadian women is substantial. These results identify areas for interventions among more vulnerable subgroups, and point to the need for further research in the area of risk factors for the prevention of morbidity and disability in the population.

Integrating Socio-Economic Determinants of Canadian Women's Health.

HEALTH ISSUE: The association between a number of socio-economic determinants and health has been amply demonstrated in Canada and elsewhere. Over the past decades, women's increased labour force participation and changing family structure, among other changes in the socio-economic environment, have altered social roles considerably and lead one to expect that the pattern of disparities in health among women and men will also have changed. Using data from the CCHS (2000), this chapter investigates the association between selected socio-economic determinants of health and two specific self-reported outcomes among women and men: (a) self-perceived health and (b) self-reports of chronic conditions. KEY FINDINGS: The descriptive picture demonstrated by this CCHS dataset is that 10% of men aged 65 and over report low income, versus 23% of women within the same age bracket. The results of the logistic regression models calculated for women and men on two outcome variables suggest that the selected socio-economic determinants used in this analysis are important for women and for men in a differential manner. These results while supporting other results illustrate the need to refine social and economic characteristics used in surveys such as the CCHS so that they would become more accurate predictors of health status given that there are personal, cultural and environmental dimensions to take into account. RECOMMENDATIONS: Because it was shown that socio economic determinants of health are context sensitive and evolve over time, studies should be designed to examine the complex temporal interactions between a variety of social and biological determinants of health from a life course perspective. Examples are provided in the chapter.

New approaches to immigrant health assessment.

While immigrant subgroups may present vulnerabilities in terms of health status, health service use, and social determinants, comprehensive information on their health is lacking. To examine mortality (1980-1998) and health service utilization (1985-2002) patterns in Canadian immigrants, a record linkage pan-Canadian research initiative using immigration and health databases has been undertaken. Preliminary results indicate that overall mortality is low among Canadian immigrants as compared to the general population for most leading causes (thus supporting the notion of "healthy immigrant effect"), with cause-specific exceptions. Moreover, results from British Columbia show that overall physician visits are low for immigrants, but not for all subgroups. Results from Ontario demonstrate a sharp increase in physician claims approximately three months following landing. Future analyses will address the short- and long-term health outcomes of immigrant subgroups, including less common diseases. Results are pertinent to practitioners working with immigrants and can inform immigrant health policy.
