Recent crises have underscored the importance that housing has in sustaining good health and, equally, its potential to harm health. Considering this and building on Howden-Chapman’s early glossary of housing and health and the WHO Housing and Health Guidelines, this paper introduces a range of housing and health-related terms, reflecting almost 20 years of development in the field. It defines key concepts currently used in research, policy and practice to describe housing in relation to health and health inequalities. Definitions are organised by three overarching aspects of housing: affordability (including housing affordability stress (HAS) and fuel poverty), suitability (including condition, accessibility and sustainable housing) and security (including precarious housing and homelessness). Each of these inter-related aspects of housing can be either protective of, or detrimental to, health. This glossary broadens our understanding of the relationship between housing and health to further promote interdisciplinarity and strengthen the nexus between these fields.
Background
Persistent exposure to environmental noise in people’s homes has been associated with cardiovascular disease and poor mental health. Many studies conducted on noise and health are based on observational studies and the extent to which findings reflect residual confounding are not known.
Methods
Using the Household, Income and Labour Dynamics survey in Australia, we examine the impact of environmental noise (traffic, airplanes, train, industry) on self-reported mental health measured by the Short Form 36 Health Survey. Fixed-effects longitudinal regression analyses are used to account for differences between people over time, reducing confounding from time-invariant factors and reporting bias. Time-varying factors were adjusted including age, education, equivalised income, employment, household structure, chronic condition, government payment status and tenure type.
Results
Results show a significant decrease in average mental health as the level of noise increased. Exposure to loud traffic noise ‘fairly commonly’ or ‘very commonly’ negatively impacted mental health (-1.18; 95%CI -1.56, -0.81 and -1.33; 95%CI -1.77, -0.89) and exposure to noise from airplanes, trains or industry ‘fairly commonly’ or ‘very commonly’ negatively impacted mental health (-1.57; 95%CI -1.88, -1.27 and -1.48; 95%CI -1.89, -1.08).
Conclusions
This provides robust evidence of short-run mental health effects of noise exposure within people’s homes. More research could be done to explore this over a longer-time frame.
Key messages
With increasing numbers of people living in urban areas, reducing environmental noise near people’s homes or improving the capacity of homes to reduce external sources of noise (e.g. double glazing) may have public health benefit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
