A research endeavor has discovered that the act of renting a home can expedite the process of biological aging more dramatically than even joblessness, indicating the significant health ramifications of stable housing. Factors contributing to this accelerated aging range from financial burdens to environmental issues; however, the process may be reversible. This underscores the crucial importance of housing policies on public health. The scholars conducting the study accentuate the potential for policy adjustments, such as bolstering protections for renters, to alleviate these adverse health outcomes.
The significance of renting, in comparison to full property ownership, is doubly as impactful as the distinction between being employed and unemployed. The research implies that these detrimental effects can indeed be mitigated, reiterating the central role that housing policies play in enhancing public health.
The biological ramifications of renting rather than owning a home are almost twice as considerable as the difference between being employed and unemployed, according to the study’s findings.
The research team stresses that these health implications are reversible and highlight the vital influence of housing regulations on improving health.
Interplay Between Housing Factors and Health
Various dimensions of housing correlate with both physical and mental well-being, such as temperature, mold infestations, overcrowding, risk of injury, stress, and societal stigma. The mechanisms through which these factors operate remain somewhat nebulous, according to the researchers.
In a bid to delve deeper into this matter, the researchers utilized epigenetic data, social surveys, and indicators of biological aging, as evidenced by DNA methylation in blood specimens.
Epigenetics refers to the study of how behaviors and external conditions can instigate changes that modify gene function. DNA methylation is a form of chemical change to DNA that can influence gene activity.
The study made use of information from the representative UK Household Longitudinal Study (UKHLS) and the British Household Panel Survey (BHPS), which was later integrated into the UKHLS.
They scrutinized data from the UKHLS on housing’s material attributes, such as type of building, government assistance available to renters, and the availability of central heating, along with psychosocial factors like housing expenses, late payments, overcrowding, and relocation tendencies.
Subsequent health information was gathered from 1420 participants of the BHPS survey, along with blood samples for DNA methylation analysis. Historical housing information was aggregated from BHPS survey responses spanning the prior decade for each participant.
In their analysis, the researchers took into account other influential variables like gender, nationality, educational background, socioeconomic status, dietary habits, cumulative stress, financial difficulties, urban living conditions, body mass index, and smoking habits. The acceleration of biological aging in line with chronological aging was also considered.
The scrutiny revealed that residing in a privately rented dwelling was correlated with more rapid biological aging. Furthermore, the influence of renting privately, as opposed to outright ownership, was nearly twice that of unemployment. It also exceeded the impact of having been a former smoker by 50%.
Additional variables such as recurrent late payments and environmental pollution were also linked to accelerated biological aging. However, living in social housing, considering its lower cost and higher tenancy stability, showed no differential impact on biological aging when additional housing parameters were considered.
Study Caveats and Final Remarks
While the study is observational and cannot conclusively establish causality, the researchers acknowledge limitations such as the absence of modern housing quality metrics and the ethnicity of the DNA methylation sample being confined to White Europeans.
The researchers conclude by stating, “Our findings point to the fact that precarious housing situations contribute to deteriorated health via accelerated biological aging. Yet this biological aging can be reversed, signifying a substantial opportunity for housing policy reforms to enhance public health.”
They further argue that their conclusions are likely transferable to other nations with comparable housing regulations and propose that reforms like terminating ‘no-fault’ evictions, capping rent increases, and improving living conditions could mitigate the negative health outcomes associated with private renting.

Frequently Asked Questions (FAQs) about Biological Impact of Renting on Health
What is the main focus of the research study?
The primary focus of the research study is to examine the impact of renting a home on biological aging, in comparison to other factors like unemployment. The study suggests that renting can significantly accelerate the process of biological aging, which has substantial implications for public health.
What factors contribute to accelerated biological aging when renting a home?
Factors contributing to accelerated biological aging when renting include financial struggles, environmental conditions, and housing quality. The study also considered psychosocial elements such as housing costs, payment arrears, and overcrowding.
How was the study conducted?
The study utilized data from the UK Household Longitudinal Study (UKHLS) and the British Household Panel Survey (BHPS). Researchers analyzed various material and psychosocial aspects of housing along with epigenetic information and indicators of biological aging like DNA methylation in blood samples. Influential variables such as gender, nationality, education, and socioeconomic status were also considered in the analysis.
Are the adverse health impacts of renting reversible?
Yes, the research emphasizes that the adverse health impacts, including accelerated biological aging, are potentially reversible. This highlights the critical role that housing policies could play in improving public health outcomes.
What housing policies could mitigate the negative health impacts of renting?
The researchers suggest that policies aimed at reducing stress and uncertainty associated with renting, such as ending ‘no-fault’ evictions, limiting rent increases, and improving living conditions, could potentially mitigate the adverse health impacts.
What are the limitations of the study?
The study is observational and cannot definitively establish causality. Additionally, there were limitations like the absence of contemporary measures of housing quality and the fact that DNA methylation data was collected only from White, European respondents.
What is the significance of epigenetics and DNA methylation in this study?
Epigenetics describes how behaviors and environmental factors can cause changes that alter the way genes function. DNA methylation is a chemical modification to DNA that can influence gene activity. These factors were used as indicators to understand the biological aging process in relation to housing conditions.
Was the research focused solely on the UK?
While the data was drawn from UK-based surveys, the researchers argue that their findings are likely relevant to other countries with similar housing policies.
Who funded the research study?
The research was financially backed by the National Health and Medical Research Council Centre of Research Excellence in Healthy Housing and the Economic and Social Research Council.
Where was the study published?
The study was published in the Journal of Epidemiology & Community Health on October 10, 2023, with the DOI: 10.1136/jech-2023-220523.
