The health impacts of housing improvement: a systematic review of intervention studies from 1887 to 2007

Childhood Housing Condition and Old Age Health Among Chinese: The Mediation Role of Adulthood Socioeconomic and Medical History

Guided by the lifecourse perspective and social determinants of health framework, this study examined the association of childhood housing with old age health among Chinese and its midlife mediators. Respondents were middle-aged and older adults (aged 45+) from the China Health and Retirement Longitudinal Study (N = 12,842). They were asked about their childhood housing conditions (e.g., if their houses had clean water, water toilet, and electricity). Adulthood socioeconomic and medical history and middle- and old-age health were measured. Causal mediation analysis showed childhood better housing was directly associated with fewer depressive symptoms and better cognition in middle- and older-age, and indirectly through increasing education level. However, the proportion-mediated estimate had very wide confidence intervals. Our findings suggested the importance of broad infrastructure development and adult continuing education programs among those who grew up in poor housing conditions to promote mental health in older age.

Housing for care, connection, and health equity

Researchers and policymakers have used a four-pillar framework- condition, consistency, context, and cost-to describe the characteristics of housing that are important for health equity. We propose adding a fifth pillar: care and connection. Housing for care and connection refers to the housing design, institutional policies, and housing programs that strengthen social connections, caregiving relationships, access to resources, and a sense of self in community. Attending to these needs in housing is especially important for people who are in transition in and out of homelessness, living in poverty, are very young or very old, or living with a disability or activity limitation.

Structural changes in a Danish social housing area: The impact of forced permanent rehousing on contact frequency with general practitioner and use of antidepressants

There is a lack of knowledge about the health consequences of politically initiated forced permanent rehousing (FPR) of residents in social housing areas. This study investigates if FPR is associated with the contact frequency with general practitioner (GP) and the proportion of residents who use antidepressants. The study included 432 rehoused residents matched 1:2 with remaining residents and residents from a comparable neighbouring area without exposure to rehousing. For GP contact frequency, we conducted a difference-in-difference analysis while the proportion of residents who used antidepressants was investigated through descriptive statistics. We found high GP contact frequency in the three groups, but no significant differences. Further, we found a low proportion of residents who used antidepressants in all groups, but a small increase from baseline to follow-up. Our results thus suggest that FPR neither affected the rehoused residents' GP contact frequency nor the proportion who used antidepressants.

Health effects of holistic housing renovation in a disadvantaged neighbourhood in the Netherlands: a qualitative exploration among residents and professionals

BACKGROUND

Holistic housing renovations combine physical housing improvements with social and socioeconomic interventions (e.g. referral to social services, debt counselling, involvement in decision-making, promoting social cohesion). In a deprived neighbourhood in Utrecht, the Netherlands, this paper examined residents' and professionals' experiences, ideas, and perceptions regarding holistic housing renovation, its health effects, and underlying mechanisms explaining those effects.

METHODS

Semi-structured in-depth interviews were conducted with 21 social housing residents exposed to holistic housing renovation, and 12 professionals involved in either the physical renovation or social interventions implemented. Residents were interviewed in various renovation stages (before, during, after renovation). Transcripts were deductively and inductively coded using qualitative software.

RESULTS

Residents experienced and professionals acknowledged renovation stress caused by nuisance from construction work (noise, dust), having to move stuff around, and temporary moving; lack of information and control; and perceived violation of privacy. Involvement in design choices was appreciated, and mental health improvement was expected on the long term due to improved housing quality and visual amenity benefits. Social contact between residents increased as the renovation became topic for small talk. Few comments were made regarding physical health effects. The interviews revealed a certain amount of distrust in and dissatisfaction with the housing corporation, construction company, and other authorities.

CONCLUSIONS

Renovation stress, aggravated by lack of information and poor accessibility of housing corporation and construction company, negatively affects mental health and sense of control. Potential stress relievers are practical help with packing and moving furniture, and increased predictability by good and targeted communication. Social interventions can best be offered after renovation, when residents live in their renovated apartment and the nuisance and stress from the renovation is behind them. Social partners can use the period leading up to the renovation to show their faces, offer practical help to reduce renovation stress, and increase residents' trust in their organization and authorities in general. This might also contribute to residents' willingness to accept help with problems in the social domain after renovation.

Getting to effective housing policy for health: a thematic synthesis of policy development and implementation

Impacts of housing on health are well-recognised. Despite this, housing standards have been neglected and there are gaps in healthy housing policies, particularly in low and middle-income countries. Given the recent publication of the WHO Housing and health guidelines, and the need to implement these into policy at all scales, we carried out a focused search and thematic synthesis of available literature on the barriers and enablers to recent housing and health policy. We aimed to generate lessons of what works to support healthy housing policy development and implementation elsewhere. Twenty-three studies representing four countries were eligible for inclusion and covered housing-related risks of air quality, lead, accessible design, and housing conditions. Findings demonstrated that policy development and implementation were facilitated through awareness of housing and health, evidence of existing housing conditions and health impacts, collaborations across sectors and between residents and decision-makers and effective enforcement systems that employed incentives, tools such as certificates for compliance, and housing inspections. Concerns about economic viability and tensions between housing rights and responsibilities limited healthy housing policy for the 'common good'. Despite limitations in the diversity of available evidence, this thematic synthesis provides a starting point for healthy and equitable housing for all.

Sponge city construction and population health

Introduction

This paper focuses on the construction of sponge cities and their effects on population health. Sponge cities in China both solve stormwater problems and are a systemic transformation in the urban construction paradigm, addressing related issues arising from high-speed urbanization. Whether sponge city construction in China can promote population health has received scant attention. Most previous studies have focused on urban environments and population health, with few exploring the potential effects on population health caused by urban environment changes due to urban policies. This study hypothesizes that sponge city construction improves the urban environment, and thus, population health.

Methods

Using panel data from 119 prefecture-level cities between 2011 and 2019 and the China Labor-force Dynamics Survey (CLDS), based on China's sponge city pilot policy, a quasi-natural experiment is conducted using Difference-in-Differences (DID) model to identify the health effects of the sponge city policy.

Results

The findings show that sponge city pilot policy not only reduced ecological environment pollution and promoted the quality of built environment, but also significantly improved population health by 10.4%. This mechanism is mainly due to the restorative effects of the built environment.

Discussion

The health effects vary across city administrative levels, and especially among non-older adults and local populations. Compared with the cities at higher administrative level, the health effect in lower administrative level is significantly positive, indicating that there is a diminishing marginal effect of sponge city construction. This study extends the causal identification chain of the impact of urban environment on population health to urban policies and provide insights into policy objectives for sponge city construction.

Housing tenure and disability in the UK: trends and projections 2004-2030

Introduction

Housing is a major influence on health. Housing tenure is associated with housing conditions, affordability, and security and is an important dimension of housing. In the UK there have been profound changes in both housing conditions and the distribution of households by tenure over the past century, that is during the lifetimes of the current population.

Methods

We firstly reviewed and summarise changes in housing conditions, housing policy and tenure distribution as they provide a context to possible explanations for health variations by housing tenure, including health related selection into different tenure types. We then use 2015-2021 data from a large nationally representative UK survey to analyse associations between housing tenure and self-reported disability among those aged 40-69 controlling for other socio-demographic factors also associated with health. We additionally examine changes in the association between housing tenure and self-reported disability in the population aged 25 and over in the first two decades of the 21st century and project trends forward to 2030.

Results

Results show that associations between housing tenure and disability by tenure were stronger than for any other indicator of socio-economic position considered with owner-occupiers having the best, and social renters the worst, health. Differences were particularly marked in reported mental health conditions and in economic activity, with 28% of social renters being economically inactive due to health problems, compared with 4% of owner-occupiers. Rates of disability have increased over time, and become increasingly polarised by tenure. By 2020 the age standardised disability rate among tenants of social housing was over twice as high as that for owner occupiers, with projections indicating further increases in both levels, and differentials in, disability by 2030.

Discussion

These results have substantial implications for housing providers, local authorities and for public health.

A happy home? Socio-economic inequalities in depressive symptoms and the role of housing quality in nine European countries

BACKGROUND

This study examines the prevalence of and socio-economic inequalities in depressive symptoms in nine high-income European countries, focusing in particular on the role of housing quality.

METHODS

Using the European Social Survey, a concentration index of depressive symptoms in each country is estimated. The role of housing quality is assessed by examining the risk factors associated with the concentration index, using the Recentred Influence Function method. To contextualise the housing quality results, other predictors of inequalities in depressive symptoms inequalities are also quantified and discussed.

RESULTS

Our results indicate that inequalities in depressive symptoms are concentrated among poorer respondents both in each country and in total. Austria and Belgium have the lowest inequalities and France has the highest. No geographic pattern is evident. Housing problems are associated with higher inequalities in six of the nine countries in the sample. While no association is evident for indicators of socio-economic status such as years of education and income, financial strain is significant.

CONCLUSIONS

This study is the first to estimate the degree of socio-economic inequality in depressive symptoms across European countries. The association between poor housing and poorer inequalities suggests that housing has a role to play lowering depressive symptoms inequalities.

Housing Environmental Factors Driving Falls Among Middle-Aged and Older Adults: A National Cohort Study

Background and Objectives

Housing is one of the main places where falls occur; however, few studies have examined housing environmental factors driving fall risk. This study aimed to explore the associations between housing environmental factors and falls in China.

Research Design and Methods

The study included data of middle-aged and older adults aged ≥45 years from 4 waves of the China Health and Retirement Longitudinal Study. We assessed 7 housing environmental factors: building materials, toilet types, household tidiness, household cooking fuels, and access to electricity, running water, and bathing facilities. Based on these, we divided housing environments into 3 types: good (0-2 poor factors), moderate (3-5 poor factors), and poor (6-7 poor factors). Falls incidence (yes or no) was self-reported during the survey period. We applied the Cox proportional hazard model to estimate the associations, adjusting for a set of covariates such as sociodemographic characteristics, lifestyles, and disease status.

Results

A total of 12,382 participants were analyzed, and the incidence of falls was 31.7%. According to the fully adjusted model, having a squatting toilet (hazard ratio [HR] = 1.14, 95% confidence interval [CI] = 1.03-1.26), household untidiness (HR = 1.09, 95% CI = 1.01-1.18), and solid fuel use for cooking (HR = 1.10, 95% CI = 1.02-1.18) were associated with a higher risk of falls (ps < .05), compared to their counterparts. We found a linear relationship between housing environments and falls (p for trend = .001). Specifically, moderate (HR = 1.16, 95% CI = 1.06-1.27) and poor housing environments (HR = 1.21, 95% CI = 1.08-1.34) were associated with a higher risk of falls compared to a good housing environment.

Discussion and Implications

Among middle-aged and older Chinese adults, a better household environment, including sitting toilets, tidy living conditions, and clean fuel use for cooking, may reduce the risk of falls. The evidence from our study suggests the need to implement age-friendly housing environments to prevent falls and disability in an aging society.

Early onset of care needs in the older population: The protective role of housing conditions

Most older people wish to live in their own homes as they age and to have a choice over their housing and care situation. Housing has the potential to play a key role in promoting independence, delaying and/or preventing the onset of care needs and in influencing the level and type of care provision required. However, many older people live in homes that are not suitable for their comfort and needs. Our study focuses on older people living in non-specialist housing in England and aims to i) explore how housing characteristics cluster; and ii) investigate their association with an early onset of care needs. We used four waves of a large representative longitudinal sample of people aged 50 or over, covering the period 2012 to 2020. We performed Latent Class Analysis and a Cox regression survival model to provide answers to our research questions. We found that people living in poor housing conditions or living in social rented housing are more likely to experience early onset of care needs, which may lead to a higher demand for, and utilisation of, long-term care services. We believe that gaining a better understanding of the relationship between housing-related conditions and care needs is paramount from the preventative and service provision point of view, and is of relevance to policymakers, practitioners, and current and future adult long-term care users.

Understanding the mechanisms linking holistic housing renovations to health and well-being of adults in disadvantaged neighbourhoods: A realist review

Holistic housing renovations combine physical housing improvements with social and socioeconomic interventions (e.g. referral to social services, debt counselling, involvement in decision-making, promoting social cohesion). This realist review aimed at understanding underlying mechanisms linking holistic housing renovations to health and well-being of adults in disadvantaged neighbourhoods. Following systematic and iterative searching, and relevance and quality appraisals, 18 scientific articles and reports were analysed. We identified three pathways via which physical housing improvements affect health, four pathways via which social and socioeconomic interventions affect health, and two pathways via which both reinforce each other in their health effects. Our findings are theoretically novel, relevant for those conducting holistic housing renovations, and point towards gaps in the literature.

Optimising older adults' home spaces to enhance their physical activity level: an exploratory qualitative study protocol

INTRODUCTION

Housing is a major contributing factor to health, and better housing condition has been linked to improved general and psychological health. There has also been strong evidence that the physical environment within the home setting substantially impacts sedentary behaviour and physical activity in children. However, there is a lack of research that has investigated the physical environment within the home setting in the context of older adults' physical activity levels and sedentary behaviour. Given that with increasing age, older adults spend large proportions of their time in their homes it is important to optimise older adults' home settings to support healthy ageing. Therefore, this study aims to explore older adults' perceptions around optimising their physical environment within their home space to support physical activity and subsequently facilitate healthy ageing.

METHODS AND ANALYSIS

In this formative research, a qualitative exploratory research design using in-depth interviews (IDIs) and a purposive sampling approach will be employed. IDIs will be conducted to collect data from study participants. Older adults from diverse community organisations in Swansea, Bridgend and Neath Port Talbot will formally request approval to recruit via its contacts for this formative research. The study data will be analysed thematically using NVivo V.12 Plus software.

ETHICS AND DISSEMINATION

Ethical approval for this study has been obtained from the College of Engineering Research Ethics Committee (NM_31-03-22), Swansea University. The findings of the study will be disseminated to the scientific community and to the study participants. The results will enable us to explore the perceptions and attitudes of older adults towards physical activity within their home environment.

Homes and health in the Outer Hebrides: A social prescribing framework for addressing fuel poverty and the social determinants of health

Health services are increasingly being reshaped with reference to addressing social determinants of health (SDoH), with social prescribing a prominent example. We examine a project in the Outer Hebrides that reshaped and widened the local health service, framing fuel poverty as a social determinant of health and mobilising a cross-sector support pathway to make meaningful and substantive improvements to islanders' living conditions. The 'Moving Together' project provided support to almost 200 households, ranging from giving advice on home energy, finances and other services, to improving the energy efficiency of their homes. In so doing, the project represents an expansion of the remit of social prescribing, in comparison with the majority of services currently provided under this banner, and can be seen as a more systemic approach that engages with the underlying conditions of a population's health. We present a framework through which to understand and shape initiatives to address fuel poverty through a social prescribing approach.

An investigation of child health in relation to housing renovations for a disadvantaged immigrant population in Malmö, Sweden

Aims:

The aim of the study was to describe child health in relation to housing renovations in more than 800 rental units, consisting of repairs of dilapidated kitchens and bathrooms, in the disadvantaged neighbourhood of Herrgården in Rosengård, Malmö, Sweden.

Methods:

Data on housing conditions and self-reported health were collected during home visits to families living in Herrgården (building renovations area) and a comparison area (neighbouring Törnrosen, with generally better housing conditions). At baseline, 130 families with 359 children participated, while 51 families with 127 children participated at follow-up. All data were collected between 2010 and 2012. Additionally, regional register data on health-care usage/in- and outpatient contacts within the public health-care system between 2008 and 2013 were also collected for all 8715 children registered as living in the two areas.

Results:

Self-reported health seemed to somewhat improve in both areas, with 74% versus 86% and 78% versus 88% reporting good or very good health in Herrgården and in the comparison area at baseline and follow-up, respectively. In Herrgården, crowdedness increased, while it decreased in the comparison area. The number of health-care contacts remained stable over time in Herrgården, while it decreased in the comparison area.

Conclusions:

Partial housing renovations did not seem to result in clear health improvements as measured with the indicators used in the present study. This could possibly be due to persisting health effects due to increased crowdedness or persisting poor housing conditions, as only kitchens and bathrooms were renovated.

Gender differences in association of urbanization with psychological stress in Chinese adults: A population-based study

Objective

To investigate the gender-specific associations between exposure to urbanization and psychological stress in China experiencing rapid urbanization.

Methods

Data were obtained from the 2015 China Health and Nutrition Survey. A total of 4,388 men and 5,098 women aged at least 18 years were obtained from 288 communities across 12 provinces and municipalities. Tertiles of the urbanization index, summarizing 12 urbanization dimensions at the community level, were used to define low, medium, and high levels of urbanization. The psychological stress was measured based on the 10-item Perceived Stress Scale. The gender-stratified multilevel analysis (Level-1: Individuals, Level-2: Communities, and Level-3: provinces/municipalities) was used to estimate the association between exposure to urbanization and psychological stress.

Results

After controlling for age, education status, marital status, work status, household income per capita, current smoking, alcohol drinking, sleep duration, BMI, and chronic conditions, the urbanization index was negatively associated with psychological stress in women (P _trend = 0.017) but not men (P _trend = 0.476). More specifically, a one-standard deviation increase in the score of community population density (β = -0.329, P = 0.329), modern markets (β = -0.247, P = 0.044), education (β = -0.448, P = 0.002), and housing (β = -0.380, P = 0.005) was negatively associated with psychological stress only in women, separately.

Conclusion

Our data revealed that living in the most urbanized communities is associated with lower levels of psychological stress for women but not men. Thus, this study can help empower decision-makers to accurately target vulnerable communities and plan effective strategies to address psychological outcomes.

Association Between Urban Regeneration and Healthcare-Seeking Behavior of Affected Residents: A Natural Experiment in two Multi-Ethnic Deprived Housing Areas in Denmark

Area regeneration of deprived neighborhoods is being used to reduce health inequality, socioeconomic deprivation and ethnic segregation. This quasi-experimental study examines if long-term graded exposure to urban regeneration is associated with primary healthcare-seeking behavior among residents. We compared general practitioner (GP) contacts from 2015-2020 in two adjacent, deprived social housing areas, one exposed to area regeneration. Populations were into Western and non-Western males and females aged 15 years and older (N = 3,960). Mean annual GP contact frequency for each group were estimated and a difference-in-difference (DiD) analysis was conducted with adjustments for propensity scores based on baseline characteristics. GP contact frequency increased for all groups across time with a systematically higher level and faster increase in the control groups. In particular, the mean difference between the exposed and control area for non-Western women more than doubled from -0.61 to -1.47 annual contacts across the period. The mean differences in contact frequency increased for all groups but results of the DiD analyses were insignificant. In conclusion, an emerging gap in GP contact frequency, with the highest levels in the control area, was observed for all comparisons across time. More long-term research is needed to understand how the emerging gaps evolve.

Using Regulatory Stances to See All the Commercial Determinants of Health

Policy Points The commercial determinants of health (CDoH) concept, which currently focuses on markets that harm health, should be expanded to refer to the interface between commerce and health, which can sometimes have positive public health consequences. The regulatory stances framework helps us classify public health preferences for regulating specific markets related to CDoH, based on the intended effects of regulations on market size. The regulatory stances a jurisdiction can adopt can be classified as ranging from prohibitionist through contractionist, permissive, and expansionist, to universalist. The regulatory stances framework increases the usefulness of the CDoH concept by expanding the conversation beyond negative determinants of health and providing a fuller view of the tools at the disposal of society to alter markets and improve health.

CONTEXT

The effects of commerce on the public health are omnipresent. The commercial determinants of health (CDoH) represent a burgeoning area of scholarly debate and activist policymaking to redress markets that adversely affect public health. The CDoH debate is a logical extension of the tobacco control movement, but, to its detriment, the CDoH conversation remains primarily focused policies and proposals that are analogous to historical tobacco control strategies.

METHODS

This paper argues that for the CDoH to develop further and broaden its appeal, it should expand to cover markets with conditional and positive impacts on health. To explain and order this conversation, a comparative framework for regulatory policy is introduced: the regulatory stances. The regulatory stances classify a regulatory policy based on the intended effect of policy on the size of a market in the future relative to the present.

FINDINGS

Some markets that interface between commerce and health do not inherently harm health. Regulatory policy toward these markets should be different in intent than regulatory policy for markets with negative health effects.

CONCLUSIONS

By using the regulatory stances framework to encompass markets that have positive or conditional effects on health as well as those that have adverse health effects, the CDoH conversation can shift away from the exclusive focus on strategies to shrink markets with adverse health impacts to consider a wider array of policy options.

Home Energy Upgrades as a Pathway to Home Decarbonization in the US: A Literature Review

This work aims to characterize how home energy upgrade projects and programs in the US have evolved over the past decade. It also identifies what changes are needed to drive expansion of the US energy retrofit market in such a way that addresses carbon emissions from buildings, improves resilience and upgrades the housing stock. This review focuses on whole-home energy upgrades, targeting deep energy retrofit savings of >30%. The topics we cover include trends in home electrification, US and European home energy upgrade programs, energy upgrade measure costs, business economics, and health effects. Key changes in project design noted in this review include: (1) the electrification of dwellings with rapidly improving heat pump systems and low-cost solar photovoltaic technology; and (2) a shift away from high-cost building envelope strategies and towards more traditional home performance/weatherization envelope upgrades. Promising program design strategies covered include: (1) end-use electrification programs; (2) novel financing approaches; (3) the use of carbon-based program and project metrics; and (4) “one-stop shop” programs. Based on the existing market barriers, we suggest that the industry should adopt new project performance metrics. Additionally, market drivers are needed to spur widespread energy upgrades in the US housing stock. Costs must be reduced, and projects designed to appeal to homeowners and contractors.

Housing Risk Factors of Four Tropical Neglected Diseases: A Brief Review of the Recent Literature

Alongside peace, education, food, income, a stable ecosystem, sustainable resources and social justice, shelter is a prerequisite for health. According to international human rights law, everyone is entitled to an adequate standard of living, which includes adequate housing. Adequate housing, including access to water and sanitation, plays a critical role in the prevention and management of neglected tropical diseases, which affect over 1 billion people worldwide. Inadequate housing conditions represent a risk factor for many of them, e.g., Chagas disease that affects 6–8 million people worldwide, visceral leishmaniasis that kills 20,000–30,000 people/year, lymphatic filariasis which threatens 859 million people worldwide or dengue that has increased 8–10 fold over the last two decades. Vector control strategies for the above-mentioned diseases have shown their effectiveness and should include systematic and repetitive in-house spraying and individual protection (e.g., impregnated nets), as well as better-quality construction material and techniques and better sanitation infrastructures and practices. Access to adequate housing is a basic human right. The violation of the right to adequate housing may affect the enjoyment of other human rights. Access to adequate housing can strengthen (and facilitate access to) other basic human rights, such as the rights to work, health, security, and education.

Quantitative methods for climate change and mental health research: current trends and future directions

The quantitative literature on climate change and mental health is growing rapidly. However, the methodological quality of the evidence is heterogeneous, and there is scope for methodological improvement and innovation. The first section of this Personal View provides a snapshot of current methodological trends and issues in the quantitative literature on climate change and mental health, drawing on literature collected through a previous scoping review. The second part of this Personal View outlines opportunities for methodological innovation concerning the assessment of the relationship between climate change and mental health. We then highlight possible methodological innovations in intervention research and in the measurement of climate change and mental health-related variables. This section draws upon methods from public mental health, environmental epidemiology, and other fields. The objective is not to provide a detailed description of different methodological techniques, but rather to highlight opportunities to use diverse methods, collaborate across disciplines, and inspire methodological innovation. The reader will be referred to practical guidance on different methods when available. We hope this Personal View will constitute a roadmap and launching pad for methodological innovation for researchers interested in investigating a rapidly growing area of research.

Hotels as Noncongregate Emergency Shelters: An Analysis of Investments in Hotels as Emergency Shelter in King County, Washington During the COVID-19 Pandemic

This study analyzes the COVID-19 homelessness response in King County, Washington, in which people were moved out of high-density emergency shelters into hotel rooms. This intervention was part of a regional effort to de-intensify the shelter system and limit the transmission of the virus to protect vulnerable individuals experiencing homelessness. This study used quantitative and qualitative methods to describe the experiences of and outcomes on individuals who were moved from shelters to noncongregate hotel settings. The study highlights a new approach to shelter delivery that not only responded to the public health imperatives of COVID-19, but also indicated positive health and social outcomes compared to traditional congregate settings. The findings establish an evidence base to help inform future strategic responses to homelessness as well as to contribute to the broader policy conversations on our nation's response to homelessness.

Effectiveness of an Energy-Counseling Intervention in Reducing Energy Poverty: Evidence from a Quasi-Experimental Study in a Southern European City

Energy poverty is a serious social problem with well-known adverse health consequences. This problem has been addressed mainly through improvements in the energy efficiency of housing. Still, little is known about the effects of information-based measures on energy poverty and their impacts on health. A quasi-experimental study was implemented to assess the effectiveness of an energy-counseling home visit intervention targeting the vulnerable population in a southern European city, Barcelona, in alleviating energy poverty and improving health. The intervention had beneficial impacts on keeping homes at an adequate indoor temperature and reducing primary care visits. No effects were found on self-perceived health or self-reported anxiety and depression. After the intervention, participants reported a decrease in arrears on utility bills, but less pronounced than in the comparison group. In conclusion, the study showed that information-based measures lead to psychosocial gains and reduced healthcare use. Nevertheless, the impact of these measures could be enhanced by combining them with policies and programmes that address the structural determinants of energy poverty.

The Role of Behavioral Medicine in Addressing Climate Change-Related Health Inequities

Climate change is the greatest threat to global health in human history. It has been declared a public health emergency by the World Health Organization and leading researchers from academic institutions around the globe. Structural racism disproportionately exposes communities targeted for marginalization to the harmful consequences of climate change through greater risk of exposure and sensitivity to climate hazards and less adaptive capacity to the health threats of climate change. Given its interdisciplinary approach to integrating behavioral, psychosocial, and biomedical knowledge, the discipline of behavioral medicine is uniquely qualified to address the systemic causes of climate change-related health inequities and can offer a perspective that is currently missing from many climate and health equity efforts. In this article, we summarize relevant concepts, describe how climate change and structural racism intersect to exacerbate health inequities, and recommend six strategies with the greatest potential for addressing climate-related health inequities.

A Place-based Evaluation of a Healthy Homes Initiative

ISSUE ADDRESSED

Limited qualitative evaluations of healthy homes initiatives exist in the literature and even fewer look past physical health benefits to wider health outcomes. A qualitative evaluation of Manawa Ora, a healthy homes initiative implemented by a Māori health provider in Northland, New Zealand, was conducted to ascertain the wider health benefits a healthy homes initiative.

METHODS

Participants of Manawa Ora were recruited, their experiences were analysed through qualitative semi-structured interviews.

RESULTS

Two main themes emerged from the semi-structured interviews. "Becoming active actors" pertains to improved health, both physical and mental, following the programme. It also describes the way participants have redirected their focus from their illness to broader, more purposeful activity. "From a simple space to a place with meaning" highlights the way Manawa Ora improved the home environment by creating a 'place' that holds meaning.

CONCLUSIONS

Healthy homes initiatives can improve physical health as well as wider health outcomes. Through the provision of beds, bedding, insulation and heating Manawa Ora has created a 'therapeutic place' out of the home that promotes healing and wellbeing.

SO WHAT

Greater focus on connections to place in public health initiatives may bring about wider health gains.

Evaluation of the Victorian Healthy Homes Program: protocol for a randomised controlled trial

INTRODUCTION

The evaluation of the Victorian Healthy Homes Program (VHHP) will generate evidence about the efficacy and cost-effectiveness of home upgrades to improve thermal comfort, reduce energy use and produce health and economic benefits to vulnerable households in Victoria, Australia.

METHODS AND ANALYSIS

The VHHP evaluation will use a staggered, parallel group clustered randomised controlled trial to test the home energy intervention in 1000 households. All households will receive the intervention either before (intervention group) or after (control group) winter (defined as 22 June to 21 September). The trial spans three winters with differing numbers of households in each cohort. The primary outcome is the mean difference in indoor average daily temperature between intervention and control households during the winter period. Secondary outcomes include household energy consumption and residential energy efficiency, self-reported respiratory symptoms, health-related quality of life, healthcare utilisation, absences from school/work and self-reported conditions within the home. Linear and logistic regression will be used to analyse the primary and secondary outcomes, controlling for clustering of households by area and the possible confounders of year and timing of intervention, to compare the treatment and control groups over the winter period. Economic evaluation will include a cost-effectiveness and cost-benefit analysis.

ETHICS AND DISSEMINATION

Ethical approval was received from Victorian Department of Human Services Human Research Ethics Committee (reference number: 04/17), University of Technology Sydney Human Research Ethics Committee (reference number: ETH18-2273) and Australian Government Department of Veterans Affairs. Study results will be disseminated in a final report and peer-reviewed journals.

"It's changed my life not to have the continual worry of being warm" - health and wellbeing impacts of a local fuel poverty programme: a mixed-methods evaluation

BACKGROUND

Living in a cold home and being fuel poor can contribute to adverse physical and mental health. Energy efficiency interventions are considered the simplest ways of tackling fuel poverty and preventing associated negative health, wellbeing, and socio-economic consequences. The overall aim of the current study was to provide a greater understanding of the impact of a locally administered programme, which funded the installation of major heating/insulation measures in areas of high fuel poverty, on the health and wellbeing of beneficiaries of the programme.

METHODS

A mixed-methods approach to explore the health and wellbeing impacts of a fuel poverty programme in East Sussex that took place between October 2016 and March 2018. Beneficiaries completed the Warwick-Edinburgh Mental Wellbeing Scale before and after any heating/insulation work had been completed in their home. Beneficiaries were also asked to retrospectively rate their health pre- and post-installation. Interviews with 23 beneficiaries of the programme were conducted to explore in-depth the impact of the programme on people's health and wellbeing and the wider social determinants of health.

RESULTS

A major heating/insulation measure was installed in 149 homes. The majority of measures installed were boilers (57.7%) and new central heating systems (32.2%). Self-rated health and wellbeing were significantly higher post-installation. Interviewees described clear examples of the positive impacts on physical health and wellbeing such as fewer chest infections, reduced pain, feeling less anxious and depressed, and generally feeling happier and more relaxed. Interviews also highlighted broader areas of impact such as reduced social isolation and increased use of domestic space. Many of the beneficiaries also reported a reduction in their energy bills since their new heating systems had been installed.

CONCLUSIONS

The findings from the evaluation suggest that the installation of major heating or insulation measures such as new boilers have substantial benefits for the health and wellbeing of beneficiaries. The findings also suggest that the programme had a positive impact on wider determinants of health including reduction in stress and isolation that are likely to be part of the pathways between fuel poverty interventions and mental and physical health outcomes.

Challenges and lessons learnt from conducting a health survey in an ethnically diverse population

Aim: To document the challenges of developing and executing an interviewer-driven survey questionnaire in an ethnically diverse and deprived social housing area undergoing reconstruction in Denmark. Methods: The survey was initially planned to be conducted in three waves (before, during and after reconstruction of the housing area), based on a questionnaire covering health, wellbeing and social relations. The first two waves took place in 2018 and 2019 (invited n=~600 per wave) and the third wave will be conducted once the reconstruction is finalised. The approach to the third wave is under revision by the research team. The questionnaire was translated from Danish into the seven most common languages in the housing area. A bilingual interview team went door to door interviewing residents. Field notes were collected systematically during each wave to document the process. Results: The response rates were 35% (n=209) and 22% (n=132) for waves 1 and 2, respectively. There was an overall decrease in response rates between waves 1 and 2 for all language groups, but particularly for Arabic and Turkish-speaking men. The most frequently stated reasons for non-participation included illness and language barriers. The key lessons learnt were that overcoming linguistic and cultural barriers to conducting research among residents in this social housing area requires time and resources. Conclusions: Several challenges are associated with conducting a survey in ethnically diverse and deprived social housing areas. Documenting the challenges and learning from experience are both important, in order to include this hard-to-reach population in health research.

Social Determinants of Health: Considerations for Athletic Health Care

Health disparities are prevalent issues in the United States and a frequent topic of conversation in the public health realm. Causes of health disparities include social inequities and social determinants of health. Although social determinants of health have been suggested to contribute more to individual and population health than the health care provided, this concept in athletic health care has received little attention. Therefore, the purpose of this article is to describe social determinants of health, present examples of social determinants, and discuss awareness of actionable steps for the athletic training profession to be more culturally proficient. By increasing awareness of and acknowledging social determinants of health, athletic trainers will be positioned to improve patient outcomes more readily and contribute to ongoing conversations at the policy level of health care.

The Influence of Living Conditions on Self-Rated Health: Evidence from China

Despite growing attention to living conditions as a social determinant of health, few studies have focused on its diverse impacts on self-rated health. Using data from the China Family Panel Study in 2018, this study used logistic regression analysis to examine how living conditions affect self-rated health in China, finding that people cooking with sanitary water and clean fuel were more likely to report good health, and that homeownership was associated with higher self-rated health. The self-rated health of people living in high-quality housing was lower than that of people living in ordinary housing, and people living in tidy homes were more likely to report good health. The findings suggest that the link between multiple living conditions and self-rated health is dynamic. Public health policies and housing subsidy programs should therefore be designed based on a comprehensive account of not only housing grade or income status, but also whole dwelling conditions.

Effect of housing condition on quality of life

This study examined the housing effect on quality of life among Japanese people. In the current cross-sectional study, we analyzed the 1-year of data (November 2015-March 2016) with 2533 participants. We used the Short Form-8 questionnaire, an 8-item instrument that measures general aspects of health-related QOL. Comprehensive Assessment System for Built Environment Efficiency housing checklist which was developed by Ministry of Land, Infrastructure, Transport and Tourism was used to assess the housing aspects. This checklist has six health elements including thermal comfort, acoustic environment, lighting environment, hygiene, safety, and security for 8 distinctive rooms/places of home. Multilevel analysis was done to identify the relationship between the perceived level of housing problem and PCS and MCS by clustering by sex. Compared to those who always felt unsafe at home due to interior design problem, participants who never felt unsafe showed an average of 10.51 (95% CI = 7.69-13.34, p < 0.0001) and 5.78 (95% CI = 2.90-8.65, p < 0.0001) higher physical and mental component score (better quality of life), respectively. Those who never had thermal, acoustic, lighting, hygiene, and security problems of housing also exhibited significantly better quality of life compared to participants who felt these problems.

Household finished flooring and soil-transmitted helminth and Giardia infections among children in rural Bangladesh and Kenya: a prospective cohort study

BACKGROUND

Soil-transmitted helminths and Giardia duodenalis are responsible for a large burden of disease globally. In low-resource settings, household finished floors (eg, concrete floors) might reduce transmission of soil-transmitted helminths and G duodenalis.

METHODS

In a prospective cohort of children nested within two randomised trials in rural Bangladesh and Kenya, we estimated associations between household finished flooring and soil-transmitted helminths and G duodenalis prevalence. In 2015-16, we collected stool samples from children aged 2-16 years in rural Bangladesh and Kenya. We detected soil-transmitted helminth infection using quantitative PCR (qPCR; Bangladesh n=2800; Kenya n=3094), and G duodenalis using qPCR in Bangladesh (n=6894) and ELISA in Kenya (n=8899). We estimated adjusted prevalence ratios (aPRs) using log-linear models adjusted for potential confounders.

FINDINGS

7187 (92·2%) of 7795 children in Bangladesh and 9077 (93·7%) of 9686 children in Kenya provided stool specimens that were analysed by qPCR. At enrolment, 691 (10%) households in Bangladesh and 471 (5%) households in Kenya had finished floors. In both countries, household finished flooring was associated with lower Ascaris lumbricoides prevalence (Bangladesh aPR 0·33, 95% CI 0·14-0·78; Kenya 0·62, 0·39-0·98) and any soil-transmitted helminths (Bangladesh 0·73, 0·52-1·01; Kenya 0·57, 0·37-0·88). Household finished floors were also associated with lower Necator americanus prevalence in Bangladesh (0·52, 0·29-0·94) and G duodenalis prevalence in both countries (Bangladesh 0·78, 0·64-0·95; Kenya 0·82, 0·70-0·97).

INTERPRETATION

In low-resource settings, living in households with finished floors over a 2-year period was associated with lower prevalence of G duodenalis and some soil-transmitted helminths in children.

Evaluating the health effect of a Social Housing programme, Minha Casa Minha Vida, using the 100 million Brazilian Cohort: a natural experiment study protocol

INTRODUCTION

Social housing programmes have been shown to influence health, but their effects on cardiovascular mortality and incidence of infectious diseases, such as leprosy and tuberculosis, are unknown. We will use individual administrative data to evaluate the effect of the Brazilian housing programme Minha Casa Minha Vida (MCMV) on cardiovascular disease (CVD) mortality and incidence of leprosy and tuberculosis.

METHODS AND ANALYSIS

We will link the baseline of the 100 Million Brazilian Cohort (2001-2015), which includes information on socioeconomic and demographic variables, to the MCMV (2009-2015), CVD mortality (2007-2015), leprosy (2007-2015) and tuberculosis (2007-2015) registries. We will define our exposed population as individuals who signed the contract to receive a house from MCMV, and our non-exposed group will be comparable individuals within the cohort who have not signed a contract for a house at that time. We will estimate the effect of MCMV on health outcomes using different propensity score approaches to control for observed confounders. Follow-up time of individuals will begin at the date of exposure ascertainment and will end at the time a specific outcome occurs, date of death or end of follow-up (31 December 2015). In addition, we will conduct stratified analyses by the follow-up time, age group, race/ethnicity, gender and socioeconomic position.

ETHICS AND DISSEMINATION

The study was approved by the ethic committees from Instituto Gonçalo Muniz-Oswaldo Cruz Foundation and University of Glasgow Medical, Veterinary and Life Sciences College. Data analysis will be carried out using an anonymised dataset, accessed by researchers in a secure computational environment according to the Centre for Integration of Data and Health Knowledge procedures. Study findings will be published in high quality peer-reviewed research journals and will also be disseminated to policy makers through stakeholder events and policy briefs.

Examining Housing Environments and Health Status of Older Adults with Physical Disabilities in South Korea

The present study examined the relationships between housing environments and health and well-being among older adults with physical disabilities in South Korea. Data are from the 2014 National Survey on Persons with Disabilities. We modelled four health and well-being outcomes - perceived stress, depressive symptoms, suicidal ideation, and life satisfaction - by various housing environments among 2,077 older adults with physical disabilities. The results illustrate that home ownership and perceived house accessibility are associated with health and well-being. Findings indicate that efforts to promote the health of older adults with physical disabilities need to be accompanied by improvements in their housing environment.

Social and behavioral risk reduction strategies for tuberculosis prevention in Canadian Inuit communities: a cost-effectiveness analysis

BACKGROUND

Tuberculosis (TB) is an important public health problem in Inuit communities across Canada, with an annual incidence rate in 2017 that was nearly 300 times higher than in Canadian-born non-Indigenous individuals. Social and behavioral factors that are prevalent in the North, such as commercial tobacco use, excessive alcohol use, food insecurity and overcrowded housing put individuals at higher risk for TB morbidity and mortality. We examined the potential impact of mitigation strategies for these risk factors, in reducing TB burden in this setting.

METHODS

We created a transmission model to simulate the epidemiology of TB in Nunavut, Canada. We then used a decision analysis model to assess the potential impact of several evidence-based strategies targeting tobacco use, excessive alcohol use, food insecurity and overcrowded housing. We predicted TB incidence, TB-related deaths, quality adjusted life years (QALYs), and associated costs and cost-effectiveness over 20 years. All costs were expressed in 2018 Canadian dollars.

RESULTS

Compared to a status quo scenario with no new interventions for these risk factors, the reduction strategy for tobacco use was most effective and cost-effective, reducing TB incidence by 5.5% (95% uncertainty range: 2.7-11%) over 20 years, with an estimated cost of $95,835 per TB case prevented and $49,671 per QALY gained. The addition of the food insecurity reduction strategy reduced incidence by a further 2% (0.5-3%) compared to the tobacco cessation strategy alone, but at significant cost.

CONCLUSIONS

Strategies that aim to reduce commercial tobacco use and improve food security will likely lead to modest reductions in TB morbidity and mortality. Although important for the communities, strategies that address excess alcohol use and overcrowding will likely have a more limited impact on TB-related outcomes at current scale, and are associated with much higher cost. Their benefits will be more substantial with scale up, which will also likely have important downstream impacts such as improved mental health, educational attainment and food security.

Associations between Objective and Subjective Housing Status with Individual Mental Health in Guangzhou, China

Housing is an important social determinant of mental health. However, few studies simultaneously measure the objective housing status (i.e., housing tenure, living space, housing conditions, and housing stability) and subjective housing status (i.e., housing satisfaction) as well as examine their effects on people's mental health (i.e., stress, anxiety, and depression). Thus, using a sample size of 1003 participants by two-stage random sampling survey in Guangzhou, China, this study applies multivariate ordinary least square regression models to comprehensively explore and compare the associations between objective and subjective housing status with mental health, and then analyze the moderating effects of subjective housing status on the relationships between objective housing status and mental health. The findings suggest that there are significant differences in people's mental health based on different housing status. The subjective housing status can better explain the variances in mental health than objective housing status. Also, subjective housing status may partly mitigate the adverse impacts of objective housing disadvantages on some aspects of an individual's mental health. Therefore, housing improvement policies and public health initiatives should be designed based on a comprehensive account of objective and subjective housing characteristics as well as their influences on specific aspects of mental health.

Health Inequalities During COVID-19 and Their Effects on Morbidity and Mortality

Inequalities in health have existed for many decades and have led to unjust consequences in morbidity and mortality. These have become even more apparent during the COVID-19 pandemic with individuals from black and minority ethnic groups, poorer socioeconomic backgrounds, urban and rurally deprived locations, and vulnerable groups of society suffering the full force of its effects. This review is highlighting the current disparities that exist within different societies, that subsequently demonstrate COVID-19, does in fact, discriminate against disadvantaged individuals. Also explored in detail are the measures that can and should be taken to improve equality and provide equitable distribution of healthcare resources amongst underprivileged communities.

House characteristics and condition as determinants of visible mold and musty odor: Results from three New Zealand House Condition Surveys in 2005, 2010, and 2015

This study assessed associations between house characteristics and mold and musty odor, using data from three consecutive (2005, 2010, and 2015) New Zealand House Condition Surveys, involving a total of 1616 timber-framed houses. Mold, musty odor, and house characteristics were assessed by independent building inspectors. We used multivariate logistic regression analyses mutually adjusted for other house characteristics for each survey separately. Positive and independent associations were found with tenure, ventilation, insulation, and envelope condition for both mold in living and bedrooms and musty odor. In particular, we found significant dose-response associations with envelope condition, ventilation, and insulation. Odds of mold increased 2.4-15.9 times (across surveys) in houses with the worst building envelope condition (BEC; p < 0.05-0.001 for trend); optimal ventilation reduced the risk of mold by 60% and the risk of musty odor by 70%-90% (p < 0.01 for trend). Other factors associated with mold and musty odor included: tenure, with an approximate doubling of odds of mold across surveys; and insulation with consistent dose-response patterns in all outcomes and surveys tested (p < 0.05 for trend in two surveys with mold and one survey for odor). In conclusion, this study showed the importance of BEC, ventilation, and insulation to avoiding harmful damp-related exposures.

Sekuwe (My House): building health equity through Dene First Nations housing designs

The Truth and Reconciliation Commission of Canada determined that the Dene people, among other Indigenous groups, experienced cultural genocide through policies that separated them from their lands and resources, and from their families, languages, cultures, and by forcibly sending children to Indian Residential Schools. The resultant social inequity is manifested in conditions of social injustice including inadequate housing. The Dene healthy housing research was a continuing partnership between the two Dene First Nation communities, the university and a provincial First Nation non-government organisation. This project engaged the creative energies of university students and Dene senior-high students to create and articulate Dene healthy housing so that concepts/plans/designs are ready for future funding interventions. We co-developed methods and networks to reframe housing as a social determinant of health and an important factor in social justice. This project reflects the fundamental requirement for a respectful understanding of Dene perspectives on housing and health and the need for Dene control over their built environment.

Johannesburg's 'poor housing, good health' paradox: the role of health status assessment, statistical modelling, residential context and migrant status

OBJECTIVES

The 'poor housing, good health' paradox observed by De Wet et al. (2011) across eight of Johannesburg's poorest Wards (neighbourhoods), was re-examined using: a more generic measure of self-reported health; better-specified adjustment for measured confounders; household data from a range of Wards and income strata across Johannesburg and Gauteng; and adjustment for migrant status.

STUDY DESIGN

The present study examined the relationship between (formal vs. informal) housing and self-reported health (-limited work and/or social activities) across four subsamples of respondents to the 2013 Quality of Life survey undertaken by the Gauteng City Regional Observatory: n = 1494 from households in the eight Wards examined by De Wet et al. (2011); n = 3059 from households with the lowest income tertile in Johannesburg; n = 8263 from households throughout Johannesburg; and n = 24,727 from households throughout Gauteng Province, irrespective of Ward or income.

METHODS

The relationship between housing and self-reported health in each of these subsamples was examined before and after adjustment for measured confounders identified using a temporally determined causal path diagram in the form of a directed acyclic graph.

RESULTS

Following adjustment for measured confounders, 'informal housing' was only associated with 'good' self-reported health in Johannesburg's poorest Wards (odds ratio [OR]: 1.39; 95% confidence interval [CI]: 1.07, 1.79) and Johannesburg as a whole (OR: 1.15; 95%CI: 1.00, 1.31). These associations were substantially attenuated following adjustment for migrant status (OR: 1.26; 95%CI: 0.97, 1.65; OR: 1.07; 95%CI: 0.93, 1.22, respectively).

CONCLUSIONS

While the present study found that Johannesburg's 'poor housing, good health' paradox was still evident when using a more generic/subjective (self-reported) measure of health, the apparent paradox appears to reflect, at least in part: the differential aggregation of migrant-headed households in Johannesburg neighbourhoods exhibiting a high concentration of informal housing; and the likely impact of the health-related selection on the health of migrant-headed households.

Prioritising Housing Maintenance to Improve Health in Indigenous Communities in NSW over 20 years

Many studies document the relationship between housing quality and health status. Poor housing in Aboriginal communities continues to be linked to the compromised health status of Aboriginal Australians. The New South Wales (NSW) Housing for Health (HfH) program has been assessing and repairing Aboriginal community housing across the state for 20 years using a standardised intervention methodology that aims to improve the health of Aboriginal people in NSW by improving their living environments. Items are tested and repairs are prioritised to maximise safety and health benefits and measured against 11 Critical Healthy Living Priorities (e.g., safety, facilities for washing people and clothes, removing waste and preparing food). Descriptive analysis of data collected pre- and post-intervention from 3670 houses was conducted to determine the effectiveness of the program. Analysis demonstrated statistically significant improvements in the ability of the houses to support safe and healthy living for all critical healthy living priorities post-interventions. Trend analysis demonstrated the magnitude of these improvements increased over 20 years. In 24 communities (n = 802 houses) where projects were repeated (5-17 years later), results indicate sustainability of improvements for 9 of 11 priorities. However, the overall condition of health-related hardware in Aboriginal community housing across NSW pre-intervention has not significantly changed during the program's 20 years. Results suggest a systematic lack of routine maintenance and quality control continues to be the overwhelming cause for this lack of improvement pre-intervention. Our evaluation of the HfH program demonstrated that fidelity to a standardised housing testing and repair methodology to improve residents' safety and health can have sustainable effects on housing infrastructure and associated health benefits, such as a 40% reduction in infectious disease hospital separations. Housing and health agencies should collaborate more closely on social housing programs and ensure programs are adequately resourced to address safety and health issues.

Evaluating Housing Health Hazards: Prevalence, Practices and Priorities in Delhi's Informal Settlements

Housing quality is crucially linked to health and sustainability goals, yet there is limited research on informal housing and settlements where housing quality is poor, and the health risks are expected to be greatest. This paper describes the investigation of housing conditions in a low-income resettlement colony in Delhi. A novel transdisciplinary methodology to evaluate multiple housing health hazards and establish intervention priorities in participation with the community was developed. Findings from housing surveys and indoor environmental monitoring were contrasted with a participatory self-assessment-revealing the widespread prevalence of hazards and suboptimal housing conditions as well as substantial differences in priorities, and thus perspectives, between participants and researchers. Focus group discussions explored the findings and built consensus on priorities. Our findings uncovered how poor housing conditions affect daily practices and thus are likely to adversely affect socio-economic development and gender equality. We highlight limitations in current frameworks to assess housing hazards and argue that a transdisciplinary approach is vital to provide a holistic understanding and to develop effective interventions. These insights are crucial to inform inclusive solutions for adequate housing and human settlements that can support improved health and help achieve the sustainable development goals.

The relationship between buildings and health: a systematic review

Background

The built environment exerts one of the strongest directly measurable effects on physical and mental health, yet the evidence base underpinning the design of healthy urban planning is not fully developed.

Method

This study provides a systematic review of quantitative studies assessing the impact of buildings on health. In total, 7127 studies were identified from a structured search of eight databases combined with manual searching for grey literature. Only quantitative studies conducted between January 2000 and November 2016 were eligible for inclusion. Studies were assessed using the quality assessment tool for quantitative studies.

Results

In total, 39 studies were included in this review. Findings showed consistently that housing refurbishment and modifications, provision of adequate heating, improvements to ventilation and water supply were associated with improved respiratory outcomes, quality of life and mental health. Prioritization of housing for vulnerable groups led to improved wellbeing. However, the quality of the underpinning evidence and lack of methodological rigour in most of the studies makes it difficult to draw causal links.

Conclusion

This review identified evidence to demonstrate the strong association between certain features of housing and wellbeing such as adequate heating and ventilation. Our findings highlight the need for strengthening of the evidence base in order for meaningful conclusions to be drawn.

Evaluating the health effects of place-based slum upgrading physical environment interventions: A systematic review (2012-2018)

Rapid urbanization in low- and middle-income countries (LMIC) is associated with increasing population living in informal settlements. Inadequate infrastructure and disenfranchisement in settlements can create environments hazardous to health. Placed-based physical environment upgrading interventions have potential to improve environmental and economic conditions linked to health outcomes. Summarizing and assessing evidence of the impact of prior interventions is critical to motivating and selecting the most effective upgrading strategies moving forward. Scientific and grey literature were systematically reviewed to identify evaluations of physical environment slum upgrading interventions in LMICs published between 2012 and 2018. Thirteen evaluations that fulfilled inclusion criteria were reviewed. Quality of evaluations was assessed using an adapted Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Findings were then pooled with those published prior to 2012. Narrative analysis was performed. Of thirteen evaluations, eight used a longitudinal study design (“primary evaluations”). All primary evaluations were based in Latin America and included two housing, two transportation, and four comprehensive intervention evaluations. Three supporting evaluations assessed housing interventions in Argentina and South Africa; two assessed a comprehensive intervention in India. Effects by intervention-type included improvements in quality of life and communicable diseases after housing interventions, possible improvements in safety after transportation and comprehensive interventions, and possible non-statistically significant effects on social capital after comprehensive interventions. Effects due to interventions may vary by regional context and intervention scope. Limited strong evidence and the diffuse nature of comprehensive interventions suggests a need for attention to measurement of intervention exposure and analytic approaches to account for confounding and selection bias in evaluation. In addition to health improvements, evaluators should consider unintended health consequences and environmental impact. Understanding and isolating the effects of place-based interventions can inform necessary policy decisions to address inadequate living conditions as rapid urban growth continues across the globe.

Do financial hardship and social support mediate the effect of unaffordable housing on mental health?

PURPOSE

Unaffordable housing has a negative impact on mental health; however, little is known about the causal pathways through which it transmits this effect. We examine the role of financial hardship and social support as mediators of this relationship.

METHODS

We identified households where housing costs changed from affordable to unaffordable across two waves of the Household, Income and Labour Dynamics in Australia (HILDA) Survey (2014-2015). The sequential causal mediation analysis was used to decompose the total effect of unaffordable housing on mental health into the portion attributable to financial hardship and social support [natural indirect effect (NIE)] and the portion not occurring through measured pathways [natural direct effect (NDE)]. Mental health was measured using the Mental Health Inventory (MHI) and Kessler psychological distress (KPD) scale. Baseline covariates included age, sex, household income, financial hardship, social support, marital status and employment status. Bootstrapping with 1000 replications was used to calculate 95% confidence intervals (CIs). Multiple imputations using chained equations were applied to account for missing data.

RESULTS

Unaffordable housing led to a change in mean mental health score on the MHI scale (- 1.3, 95% CI: - 2.1, - 0.6) and KPDS scale (0.9, 95% CI: 0.4, 1.4). Financial hardship accounted for 54% of the total effect on MHI scale and 53% on KPD scale. Collectively, financial hardship and social support explained 68% of the total effect on MHI scale and 67% on KPD scale, respectively.

CONCLUSIONS

In conclusion, the negative mental health effect of unaffordable housing is largely mediated through increased financial hardship.

European Psychiatric Association (EPA) guidance on prevention of mental disorders

There is considerable evidence that various psychiatric conditions can be prevented through the implementation of effective evidence-based interventions. Since a large proportion of lifetime mental illness starts before adulthood, such interventions are particularly important during childhood and adolescence. Prevention is important for the sustainable reduction of the burden of mental disorder since once it has arisen, treatment can only reduce a relatively small proportion of such burden. The challenge for clinicians is to incorporate such interventions into non-clinical and clinical practice as well as engaging with a range of other service providers including public health. Similar strategies can be employed in both the European and global contexts. Promotion of mental well-being can prevent mental disorder but is also important in the recovery from mental disorder. This guidance should be read in conjunction with the EPA Guidance on Mental Health Promotion. This guidance draws on preparatory work for the development of England policy on prevention of mental disorder which used a wide range of sources.

'Home is where the health is': Housing quality and adult health outcomes in the Survey of Income and Program Participation

Nearly a quarter of the homes in the United States were considered unhealthy or inadequate, but whether these housing characteristics have direct effects on health or whether they are driven by other contextual housing and neighborhood characteristics remains unclear. The purpose of this study was to quantify the independent associations between poor housing quality and adult health outcomes, adjusting for socioeconomic factors (e.g. income to poverty ratio, food insecurity) and other contextual housing characteristics (e.g. rental status, number of people per household, unsafe neighborhood). Using in-person household interview data from wave 1 of the 2014 Survey of Income and Program Participation (SIPP), a secondary analysis was performed using a series of logistic regression models. The 2014 SIPP sample is a multistage stratified sample of 53,070 housing units designed to represent the civilian, noninstitutionalized population of the United States (N = 55,281 adults ages 18 and older). Our results indicate that each additional poor housing characteristic was associated with poorer health status (OR: 1.17, CI [1.11, 1.23]), higher medical utilization (OR: 1.11 CI: [1.06, 1.16]), and a higher likelihood of hospitalization (OR: 1.07, CI [1.02, 1.12]). Non-housing-related government assistance, food security, and safe neighborhoods only partially explained associations between housing quality and health outcomes. Evaluating current local, state, and federal policy on housing quality standards may help determine if these standards decrease the number of Americans residing in inadequate homes or result in improvements in health and reductions in healthcare costs. Simply put, the home is where [we suggest] the health is.

Mental wellbeing in the Anthropocene: Socio-ecological approaches to capability enhancement

There is growing recognition that "human development" frameworks, such as the Capabilities Approach (CA) with its emphasis on the promotion of justice, offer promise for guiding efforts aimed at enhancing mental wellbeing. This article explores challenges that might arise when there is a need to arbitrate among the competing demands of different parties in their efforts to enhance capabilities. Particular tensions can arise when the efforts of particular individuals to enhance their capabilities exert pressure on scarce resources, or threaten the safety and security of people living in precarious environmental contexts. Consideration is given to the need for "an ethos of restraint" to balance the consumption of resources aimed at facilitating human development on the one hand, with the need to promote environmental justice on the other. The paper highlights research that has investigated how environmental factors can impact on mental wellbeing, including rapid urbanization, climate change related issues (such as weather systems, drought, food insecurity and rising sea-levels), and access to "green/blue spaces". As such, the paper explores the important links that can exist between people and the ecosystems in which they live (including the way in which particular cultural beliefs and practices of indigenous groups can be tethered to the land). Elinor Ostrom's "design principles", derived from her work investigating the sustainable use of pooled resources, are presented as a helpful means of assisting members of communities to negotiate and apply "functioning constraints", which can promote environmental justice whilst not compromising efforts aimed at promoting mental wellbeing.

Household energy efficiency and health: Area-level analysis of hospital admissions in England

INTRODUCTION

Fuel poverty affects up to 35% of European homes, which represents a significant burden on society and healthcare systems. Draught proofing homes to prevent heat loss, improved glazing, insulation and heating (energy efficiency measures) can make more homes more affordable to heat. This has prompted significant investment in energy efficiency upgrades for around 40% of UK households to reduce the impact of fuel poverty. Despite some inconsistent evidence, household energy efficiency interventions can improve cardiovascular and respiratory health outcomes. However, the health benefits of these interventions have not been fully explored; this is the focus of this study.

METHODS

In this cross sectional ecological study, we conducted two sets of analyses at different spatial resolution to explore population data on housing energy efficiency measures and hospital admissions at the area-level (counts grouped over a 3-year period). Housing data were obtained from three data sets covering housing across England (Household Energy Efficiency Database), Energy Performance Certificate (EPC) and, in the South West of England, the Devon Home Analytics Portal. These databases provided data aggregated to Lower Area Super Output Area and postcode level (Home Analytics Portal only). These datasets provided measures of both state (e.g. EPC ratings) and intervention (e.g. number of boiler replacements), aggregated spatially and temporally to enable cross-sectional analyses with health outcome data. Hospital admissions for adult (over 18 years) asthma, chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) were obtained from the Hospital Episode Statistics database for the national (1st April 2011 to 31st March 2014) and Devon, South West of England (1st April 2014 to 31st March 2017) analyses. Descriptive statistics and regression models were used to describe the associations between small area household energy efficiency measures and hospital admissions. Three main analyses were undertaken to investigate the relationships between; 1) household energy efficiency improvements (i.e. improved glazing, insulation and boiler upgrades); 2) higher levels of energy efficiency ratings (measured by Energy Performance Certificate ratings); 3) energy efficiency improvements and ratings (i.e. physical improvements and rating assessed by the Standard Assessment Procedure) and hospital admissions.

RESULTS

In the national analyses, household energy performance certificate ratings ranged from 37 to 83 (mean 61.98; Standard Deviation 5.24). There were a total of 312,837 emergency admissions for asthma, 587,770 for COPD and 839,416 for CVD. While analyses for individual energy efficiency metrics (i.e. boiler upgrades, draught proofing, glazing, loft and wall insulation) were mixed; a unit increase in mean energy performance rating was associated with increases of around 0.5% in asthma and CVD admissions, and 1% higher COPD admission rates. Admission rates were also influenced by the type of dwelling, tenure status (e.g. home owner versus renting), living in a rural area, and minimum winter temperature.

DISCUSSION

Despite a range of limitations and some mixed and contrasting findings across the national and local analyses, there was some evidence that areas with more energy efficiency improvements resulted in higher admission rates for respiratory and cardiovascular diseases. This builds on existing evidence highlighting the complex relationships between health and housing. While energy efficiency measures can improve health outcomes (especially when targeting those with chronic respiratory illness), reduced household ventilation rates can impact indoor air quality for example and increase the risk of diseases such as asthma. Alternatively, these findings could be due to the ecological study design, reverse causality, or the non-detection of more vulnerable subpopulations, as well as the targeting of areas with poor housing stock, low income households, and the lack of "whole house approaches" when retrofitting the existing housing stock.

CONCLUSION

To be sustainable, household energy efficiency policies and resulting interventions must account for whole house approaches (i.e. consideration of the whole house and occupant lifestyles). These must consider more alternative 'greener' and more sustainable measures, which are capable of accounting for variable lifestyles, as well as the need for adequate heating and ventilation. Larger natural experiments and more complex modelling are needed to further investigate the impact of ongoing dramatic changes in the housing stock and health.

STUDY IMPLICATIONS

This study supports the need for more holistic approaches to delivering healthier indoor environments, which must consider a dynamic and complex system with multiple interactions between a range of interrelated factors. These need to consider the drivers and pressures (e.g. quality of the built environment and resident behaviours) resulting in environmental exposures and adverse health outcomes.

Multisectoral approaches for the control of vector-borne diseases, with particular emphasis on dengue and housing

The Sustainable Development Goals suggest an intersectoral approach for development and health, including for vector-borne diseases. Evidence-based policy recommendations exist for malaria and housing, but not for other, more underfunded, vector-borne diseases. This review aims to stimulate the process for developing policy recommendations for other vector-borne diseases and housing with the process as it was developed for dengue and Aedes control as an example and with suggestions for steps necessary for other vector-borne diseases. For dengue, some basic research on the efficacy of vector control in relation to housing exists, summary evidence highlights the lack of evidence and efficacy and policy recommendations remain difficult. For other vector-borne diseases, few studies have focused on protecting the house, combinations of effective interventions (e.g. intradomiciliary residual spraying, insecticide-treated materials and treatment of larval habitats with biological and chemical methods, which have proven to be effective) have not been studied and summary evidence is non-existent. In order to recommend vector control to protect the house against vector-borne diseases, basic research and summary evidence are needed, with an appropriate combination of the most efficacious interventions and linked to improvement of housing itself. Standards for such studies need to be developed.
