Effect of Housing Quality on the Mental Health of University Students during the COVID-19 Lockdown

COVID-19 outbreak imposed rapid and severe public policies that consistently impacted the lifestyle habits and mental health of the general population. Despite vaccination, lockdown restrictions are still considered as potential measures to contrast COVID-19 variants spread in several countries. Recent studies have highlighted the impacts of lockdowns on the population's mental health; however, the role of the indoor housing environment where people spent most of their time has rarely been considered. Data from 8177 undergraduate and graduate students were collected in a large, cross-sectional, web-based survey, submitted to a university in Northern Italy during the first lockdown period from 1 April to 1 May 2020. Logistic regression analysis showed significant associations between moderate and severe depression symptomatology (PHQ-9 scores >= 15), and houses with both poor indoor quality and small dimensions (OR = 4.132), either medium dimensions (OR = 3.249) or big dimensions (OR = 3.522). It was also found that, regardless of housing size, poor indoor quality is significantly associated with moderate-severe depressive symptomatology. Further studies are encouraged to explore the long-term impact of built environment parameter modifications on mental health, and therefore support housing and public health policies.

The COVID-19 outbreak has had rapid and severe impacts on public policies, lifestyle habits, and mental health. Lockdown restrictions are still being considered to combat the spread of COVID-19 variants in many countries. A study in Italy found significant associations between poor indoor housing quality, small dimensions, and moderate-severe depression symptomatology. Further research is needed to explore the long-term impacts of the built environment on mental health.
