Aging under scarcity and insecurity: Chronic disease, functional limitation, and basic need material insecurity among older adults in Haiti
BACKGROUND: Older adults in low-income and fragile states often age with intersecting burdens of chronic disease, functional decline, and material deprivation, yet they remain largely invisible in research and policy. In Haiti, recurrent political crises, violence, and weak health and social protection systems may amplify late-life inequities, but national data are scarce. We examined the distribution and social determinants of health, functionin…
Time to move on: Exploring the journey from supportive housing to independent living for people with past homelessness experience
Supportive housing, which provides subsidized housing with on-site support, is an integral part of the housing continuum. Moving on Initiatives (MOIs) assist people living in supportive housing who no longer require on-site support to access housing in the private market, thereby increasing system capacity while offering individuals choice and control over their housing. The objective of this study was to understand the experiences of adults with…
Ethno-Racial Differences in the Effectiveness of Housing First on Healthcare Utilization Among Homeless Adults with Mental Illness: At Home Chez-Soi, a Pragmatic Randomized Trial
This study evaluates the impact of the Housing First (HF) intervention on healthcare utilization among homeless adults with mental illness, comparing ethno-racial (ER) and non-ER groups with moderate mental health support needs. We linked data from the At Home/Chez-Soi (AH/CS) randomized controlled trial with health administrative data from Ontario, including the Ontario Health Insurance Plan and several healthcare databases (e.g., Discharge Abst…
Effect of a housing intervention on major cardiovascular events among homeless adults with mental illness
Homelessness is associated with excess cardiovascular morbidity and mortality. This study reports on the long-term effects of a Canadian housing first initiative, compared to treatment as usual, on major cardiovascular events among adults experiencing homelessness and mental illness. Over the 7-year follow-up period, 34 of 527 participants (6.5%) experienced at least one cardiovascular event. There was no significant difference in the incidence o…
Differential impacts of Covid ‐19 and associated responses on the health, social well‐being and food security of users of supportive social and health programs during the Covid ‐19 pandemic: A qualita…
The effects of the coronavirus disease-2019 (COVID-19) pandemic on the lives of underserved populations are underexplored. This study aimed to identify the impacts of the COVID-19 pandemic and associated public health responses on the health and social well-being, and food security of users of Housing First (HF) services in Toronto (Canada) during the first wave of the COVID-19 pandemic. This qualitative descriptive study was conducted from July …
Localizing syndemics: A comparative study of hunger, stigma, suffering, and crime exposure in three Haitian communities
Food insecurity and mental health outcomes among homeless adults: A scoping review
Objective: This review summarises and synthesises the existing literature on the relationship between food insecurity (FS) and mental health conditions among adult individuals experiencing homelessness. Design: Scoping review. Papers published between 1 January 2008 and 2 November 2018, searched in PubMed, Web of Science, Scopus, PsycINFO, Cochrane Library and CINAHL, using homelessness, food security and mental health keywords. Setting: Global e…
The Effect of a Housing First Intervention on Acute Health Care Utilization among Homeless Adults with Mental Illness: Long-term Outcomes of the At Home/Chez-Soi Randomized Pragmatic Trial
We assessed the effects of the Toronto Site Housing First (HF) intervention on hospitalizations and emergency department (ED) visits among homeless adults with mental illness over 7 years of follow-up. The Toronto Site is part of an unblinded multi-site randomized pragmatic trial of HF for homeless adults with mental illness in Canada, which followed participants up to 7 years. Five hundred seventy-five participants were recruited and classified …
Housing First and Severe Mental Disorders: The Challenge of Exiting Homelessness
We examine the long-term housing trajectories of 543 program participants at the Toronto site of the At Home/Chez-Soi project, a randomized controlled trial of a Housing First (HF) intervention for adults with mental disorders. The average follow-up period for our study was 5.5 years. We find that the HF approach, which includes housing subsidies and support services, was strongly associated with rapid transitions to sustained housing (70.4 perce…
Housing Trajectories, Risk Factors, and Resources among Individuals Who Are Homeless or Precariously Housed
This study identifies time-patterned trajectories of housing stability among homeless and vulnerably housed individuals who participated in a multisite four-year longitudinal study in Canada. Findings show four distinct trajectories for the homeless and vulnerably housed: high levels of sustained housing stability, improving levels over time leading to high levels of housing stability, decreasing levels of housing stability over time, and low lev…
Longitudinal interrelationships of mental health discrimination and stigma with housing and well-being outcomes in adults with mental illness and recent experience of homelessness
Agricultural wealth better predicts mental wellbeing than market wealth among highly vulnerable households in Haiti: Evidence for the benefits of a multidimensional approach to poverty
OBJECTIVES: Lack of wealth (poverty) impacts almost every aspect of human biology. Accordingly, many studies include its assessment. In almost all cases, approaches to assessing poverty are based on lack of success within cash economies (eg, lack of income, employment). However, this operationalization deflects attention from alternative forms of poverty that may have the most substantial influence on human wellbeing. We test how a multidimension…
Dental problems and chronic diseases in mentally ill homeless adults: A cross-sectional study
Dental health problems in homeless individuals with serious mental disorders are associated with several CDs. Dental care should be better integrated into existing social and health programs serving this population to improve their overall health status. The AH/CS study is registered with the International Standard Randomized Control Trial Number Register (ISRCTN42520374)
Life expectancy, death, and disability in Haiti, 1990-2017: A systematic analysis from the Global Burden of Disease Study 2017
Objective. To investigate the magnitude and distribution of the main causes of death, disability, and risk factors in Haiti. Methods. We conducted an ecological analysis, using data estimated from the Global Burden of Disease Study 2017 for the period 1990-2017, to present life expectancy (LE), healthy life expectancy (HALE) at under 1-year-old, cause-specific deaths, years of life lost (YLLs), years lived with disability (YLDs), disability adjus…

A population-based study of homicide deaths in Ontario, Canada using linked death records
Homicides are an important cause of death among young males, and populations living in disadvantaged neighbourhoods. Our findings raise concerns about the burden of homicides in the Canadian population and the importance of addressing social determinants to address these premature deaths
Impact of economic fluctuations on suicide mortality in Canada (1926–2008): Testing the Durkheim, Ginsberg, and Henry and Short theories
Three theories have been proposed to explain the relationship between suicide and economic fluctuations, including the Durkheim (nonlinear), Ginsberg (procyclical), and Henry and Short (countercyclical) theories. This study tested the effect of economic fluctuations, measured by unemployment rate, on suicide rates in Canada from 1926 to 2008. Autoregressive integrated moving average time-series models were used. The results showed a significant r…
Family size and intra-family inequalities in education in Ouagadougou
While the potential benefits for educational investment of decline in family size are well known, some questions have emerged on the distribution of these benefits. Do all the children in a family benefit equitably from the improved conditions brought abou
