Housing Interventions to Improve Health


A Systematic Review of Housing Interventions and Health: Introduction, Methods, and Summary Findings
This article reviews evidence on the effectiveness of specific housing interventions to improve health. Studies were categorized according to the type of intervention, how and where it was delivered, and its target population. A description of the project's research methods and summary findings are provided along with companion articles and resources, which provide greater details about the reviewed housing interventions. NCHH also provides a report version (listed directly below) of the same findings. [url, pdf; Journal of Public Health Management & Practice, 2010]

Housing Interventions and Health: A Review of the Evidence
This report, assessing the impact of housing interventions on health, is based on an exhaustive review of scientific literature on housing and neighborhood-level interventions to improve housing. The review was conducted by a panel of health and housing experts who employed two broad categories of evidence, clinical and environmental or housing measures, to make their determination about the efficacy of the intervention. Findings ranged from sufficient evidence of effectiveness to no evidence or ineffective, with results indicating that specific housing interventions can improve certain health outcomes.

Asthma Control: Home-Based Multi-Trigger, Multicomponent Environmental Interventions

Based on a review of 23 studies, the Community Preventive Services Task Force recommends the use of home-based multitrigger, multicomponent interventions with an environmental focus for children and adolescents with asthma. The recommendations are based on strong evidence of effectiveness in improving asthma symptoms and reducing the number of school days missed due to asthma. The task force found that home-based multitrigger, multicomponent interventions with a combination of minor or moderate environmental remediation with an educational component provides good value for the money invested.

Housing Quality and Health


2013 State of Healthy Housing

This biennial report issued by NCHH assesses the health of housing using twenty key factors from the 54 communities sampled by the American Housing Survey (AHS). Local communities could create their own assessment of housing quality using similar housing quality characteristics; e.g., interior and exterior leaks, signs of pests, and other factors collected by local public health and code enforcement agencies.

Housing Code Violation Density Associated with Emergency Department and Hospital Use by Children with Asthma
Local agencies that enforce housing policies can partner with the healthcare system to target pediatric asthma care. Code enforcement agencies have data that can help pinpoint potential clusters of high asthma morbidity. This study assesses whether the density of housing code violations in census tracts and relevant violations (such as the presence of mold or cockroaches) was associated with population-level asthma morbidity. The study found that increased density in housing code violations was associated with population-level morbidity independent of poverty. [url; ResearchGate, 2014]

San Francisco Children Living in Redeveloped Public Housing Used Acute Services Less than Children in Older Public Housing
Poor housing quality is a predictor of poor health and developmental problems in low-income children. This report examined the association between public housing and recurring pediatric emergency and urgent care hospital visits. It was found that children living in non-redeveloped public housing were more likely to have one or more repeat visits within one year for acute healthcare services, compared to children who lived in redeveloped HOPE VI housing. No differences in repeat visits was found between children in redeveloped HOPE VI housing and in nonpublic housing. [url; ResearchGate, 2014]

Best Practices for Effecting the Rehabilitation of Affordable Housing
Rehabilitating and maintaining our aging housing stock is one key mechanism to help meet the nation's affordable housing needs. However, renovating affordable housing is fraught with institutional and regulatory barriers. The existing stock varies greatly in condition and age, making the rehab process far less predictable and, often, more challenging than new construction. This report from HUD examines potential solutions to some of the major barriers encountered with urban rehab projects and offers a set of practices that have successfully overcome challenges throughout every stage of the rehabilitation.

Improving Health of Housing in South King County, Washington
This paper, prepared for the Housing Development Consortium of Seattle King-County (HDC), examines policies to improve health and housing quality in South King County, WA. The authors conducted a national literature review to determine best practices to address unhealthy housing and interviewed key officials and stakeholders from cities in South King County to better understand local programs and their effectiveness. Based on their finding, the authors developed a set of best practices which they recommended be implemented in South King County to improve housing conditions and related health outcomes.

The initiative is a national effort to integrate lead hazard control, healthy homes and weatherization, and energy efficiency work. The GHHI site features key information about what makes a home green and healthy, and links to resources for homeowners and policymakers about major health hazards that can be found in homes, ranging from asbestos to pests.

Health Outcomes and Green Renovation of Affordable Housing
This article discusses an NCHH study that examined the health impact of green building renovation on residents living in a multifamily property in southwest Minnesota. The researchers found significant health improvements following low-income housing renovation that complied with green standards and recommended that all green building standards include health requirements. Additionally, they found that collaboration of housing, public health, and environmental health professionals through integrated design holds promise for improved health, quality of life, building operation, and energy conservation.

Green Rehabilitation of Elder Apartment Treatments (GREAT) Study
The GREAT study was one of the nation’s first examinations of the health outcomes among older Americans following rehabilitation using green healthy housing methods. The study hypothesized that public housing renovated using green healthy housing standards could improve the mental and physical health of residents. Evaluation activities included development of assessment protocols, data entry and analysis, execution of quality assurance activities; and completion of evaluation reports. Green renovations such as improved ventilation, moisture and mold reduction, and various safety measures resulted in improved mental and general physical health, prevented falls, and reduced exposure to tobacco smoke.

Building Products and Health


Healthy Building Network (HBN)
HBN focuses on the use of hazardous chemicals in building products and their impact on human health and the environment. The site offers current health reports about particular products commonly used in building production, such as PVC and recycled content materials, and products that impact specific health issues, such as asthma.

HBN also sponsors the Pharos Project, an independent, comprehensive database that identifies health hazards associated with building products. Pharos encourages manufacturers to disclose all ingredients in building products; helps architects, designers, and building owners avoid using products that contain harmful chemicals; and creates incentives for product redesign and modification to reduce the impacts of hazardous materials use throughout the life cycle of building products.
  • Asthmagens in Building Materials: The Problem & Solutions
    Hundreds of substances can cause the onset of asthma, many of which are common ingredients in building products such as insulation, paints, adhesives, wall panels and floors. This paper identifies asthmagens found in building products, how people can be exposed to them, and what is known and speculated about the impacts of these exposures. [url; HBN, 2014]
  • Full Disclosure Required: A Strategy to Prevent Asthma through Building Product Selection
    This exhaustive investigation of asthma-causing chemicals in building materials identifies commonly-used interior building materials likely to contain chemicals that cause the onset of asthma, examines emerging evidence of how early childhood exposures to these chemicals are of particular concern, and looks at how existing indoor air quality programs and green building rating systems do not yet address this growing public health crisis. It also provides clear strategies for preventing building occupant exposures through product disclosure and green chemistry. [url; HBN, 2013]

Health Impact Assessments (HIA)


Health Impact Project
This initiative, created through a collaboration between the Robert Wood Johnson Foundation and The Pew Charitable Trusts, promotes the use of health impact assessments (HIAs) for community development decisions. The site provides access to HIA reports conducted by communities across the county, policy briefs, research, tool kits, and training materials. One of the project's endeavors is the Collaboration for Green and Healthy Development, a partnership with Enterprise Green Communities (EGC) and the U.S. Green Building Council (USGBC) to streamline comprehensive and systematic considerations of health in the EGC Criteria and the USGBC's Leadership in Energy and Environmental Design (LEED) certification programs. Although both programs currently include health measures, it is hoped that the collaboration will serve to strengthen and expand the consideration of health. [url, pdf; Pew Charitable Trusts]
