[Homelessness as a determinant of health and its impact on quality of life].

Objective: To determine the health status of the homeless population who spend the night on the streets and in shelters (extreme residential exclusion), with reference to their quality of life, self-perceived health, comorbidity and access to health resources.

Method: A cross-sectional descriptive study was carried out on a sample of 263 homeless people in the city of Valencia by means of a nocturnal count and using the EQ-5D-3L Health Related Quality of Life questionnaire and questions from the European Quality of Life Survey for Spain.

Results: Of the people who participated in the study, 129 of them slept outdoors, 49% (62.79% men, 19.37% women and 17.84% unidentified), while 134 slept in hostels, i.e. 51% (67.16% men and 32.84% women) with an estimated average age of 41.53 years and 55% had been living on the street for less than 12 months. People staying overnight on the streets presented worse quality of life and more than a quarter of the sample lacked a health card.

Conclusions: There is a relationship between homelessness and poor health conditions in terms of quality of life, perceived health, comorbidity and accessibility to health to resources. The inverse care law is evidenced.
