Housing Quality and Mental Health: the Association between Pest Infestation and Depressive Symptoms among Public Housing Residents

Abstract

Housing quality, which includes structural and environmental risks, has been associated with multiple physical health outcomes including injury and asthma. Cockroach and mouse infestations can be prime manifestations of diminished housing quality. While the respiratory health effects of pest infestation are well documented, little is known about the association between infestation and mental health outcomes. To address this gap in knowledge and given the potential to intervene to reduce pest infestation, we assessed the association between household pest infestation and symptoms of depression among public housing residents. We conducted a cross-sectional study in 16 Boston Housing Authority (BHA) developments from 2012 to 2014 in Boston, Massachusetts. Household units were randomly selected and one adult (n = 461) from each unit was surveyed about depressive symptoms using the Center for Epidemiologic Study-Depression (CES-D) Scale, and about pest infestation and management practices. In addition, a home inspection for pests was performed. General linear models were used to model the association between pest infestation and high depressive symptoms. After adjusting for important covariates, individuals who lived in homes with current cockroach infestation had almost three times the odds of experiencing high depressive symptoms (adjusted OR = 2.9, 95% CI 1.9-4.4) than those without infestation. Dual infestation (cockroach and mouse) was associated with over five times the odds (adjusted odds = 5.1, 95% CI 3.0-8.5) of experiencing high depressive symptoms. Using a robust measure of cockroach and mouse infestation, and a validated depression screener, we identified associations between current infestation and depressive symptoms. Although the temporal directionality of this association remains uncertain, these findings suggest that the health impact of poor housing conditions extend beyond physical health to include mental health. The study adds important information to the growing body of evidence that housing contributes to population health and improvements in population health may not be possible without addressing deficiencies in the housing infrastructure.

The social impacts of bedbug infestation as an emerging public health issue: a case report

“…Based on evidence in our study, the second-hand wooden desk introduced the bedbug infestation into the house (case 3). Presence of cockroaches and rodent infestations in housing can be associated with poor health outcomes (25), but in general, concerning bedbugs, the transfer of second-hand furniture and travelling to infected places were the most common ways to bedbug infestation (26). The findings of Wang et al (2016) demonstrated the possible routes that bedbug infestation can be introduced including: second-hand items such as used furniture, visitors to households and neighboring households, from public places and bed wetting (27).…”

Effect of housing condition on quality of life

“…These results are consistent with other studies reporting that individuals who lived in homes with cockroach infestations had almost three times the odds of experiencing high depressive symptoms than those without infestation. 33 Sufficient epidemiological evidence is available from studies conducted in different countries and under different climatic conditions to show that the occupants of damp, foul-smelling, or mold-filled buildings are at increased risk of respiratory symptoms, respiratory infections, and exacerbation of asthma. 34,35 Mold is mainly caused by excessive moisture, stagnant air zones, and poor ventilation.…”

Introduction

“…In this context, relations in cities between public health and factors as diverse as open space (Brawner et al, 2017;Kondo et al, 2018), exercise (Daumann et al, 2014), police violence (Cooper and Fullilove, 2016), neighbourhood effects and spatial logics (Kwarteng et al, 2017), libraries (Morgan et al, 2017), pest infestation (Shah et al, 2018), food supply (Tach and Amorim, 2015) or race (Tung et al, 2017;Vaughan, Cohen and Han, 2018;Young and Pebley, 2018) are all assiduously mapped, indexed and located in a city space that is pathogenic in a growing science of urban public health. Such research is sophisticated and powerful.…”
