Aging faster? It must be your housing condition
In a recent study conducted by Dr Amy Clair, Emma Baker, and Meena Kumari at the Australian Centre for Housing Research, University of Adelaide, the complex interplay between housing conditions and the rate of epigenetic aging takes center stage. Drawing on data from the UK Household Longitudinal Study and the British Household Panel Survey, the research investigates the influence of housing, both contemporary and historical, on the biological aging process, as measured through DNA methylation.
The findings of this research, published in the Journal of Epidemiology & Community Health, hold significant relevance for public policy and healthcare. They suggest that challenging housing situations contribute to the acceleration of biological aging, but importantly, this aging process is also reversible. This underscores the necessity for a comprehensive housing policy approach that goes beyond affordability, encompassing the psychosocial aspects of housing. Furthermore, it highlights the critical importance of addressing environmental concerns and housing arrears to enhance overall health.
Housing-Health Nexus
Housing has long been recognized as a determinant of health, with numerous studies establishing connections between the two. Factors like access to clean water, safe living conditions, and socioeconomic disparities within housing are well-documented contributors to health outcomes. However, this new study takes a closer look at the psychosocial elements of housing and their influence on health, particularly through the lens of epigenetic aging.
Epigenetic aging is a phenomenon where changes in DNA methylation patterns are associated with the aging process. It is a critical determinant of an individual’s biological age, which may differ from their chronological age. The researchers aimed to understand how housing circumstances, both current and past, impact epigenetic aging and, consequently, overall health.
The study’s findings reveal that living in a privately rented home is associated with faster epigenetic aging. This effect is particularly pronounced when compared to other well-known factors affecting biological age, such as unemployment or smoking history.
Moreover, when historical housing circumstances are included in the analysis, the study finds that repeated housing arrears and exposure to pollution or environmental problems are also linked to accelerated epigenetic aging. These results underscore the complexity of the housing-health relationship, highlighting the long-term repercussions of housing instability and environmental challenges.
In this context, the study, which sheds light on the potential relationship between housing circumstances and epigenetic aging, emphasizes how improving housing conditions can have a positive impact on public health.
