Health Effects of Housing Insecurity and Unaffordability in the General Population in Barcelona, Spain

While the negative effects of housing insecurity and unaffordability on health are well known, most of the studies in Spain have focused on very specific social groups so their findings cannot be extrapolated to the general population. The aim of this study is to assess the effects of housing stress and risk of displacement due to economic reasons, and their combined effect, on the mental and physical health of the general population from a middle-income neighborhood of Barcelona. We conducted a cross-sectional study using a household health survey which included respondents from a representative sample of 1202 non-institutionalized residents (> 18 years old) of the Horta neighborhood. We carried out a descriptive analysis, estimated the prevalence of poor mental and self-rated health (stratifying by the independent variables) and fitted robust Poisson regression models to estimate the effects of housing stress (HS) and the risk of forced displacement (RD) on self-rated health and mental health (GHQ-12). All analyses were stratified by sex. We found a higher likelihood of poor general and mental health among people affected by HS and/or RD compared to those not affected by HS and/or RD. A graded effect of HS and RD emerged mainly on mental health, even after adjusting by socioeconomic variables and housing tenure. The serious problem of housing insecurity and unaffordability in Spain is a widespread public health issue. Evidence-based public policies to improve well-being and health of people under this threat are urgently needed.
