It has been estimated that older subjects spend approximately 19 to 20 h/day indoors. Older individuals may be particularly at risk for detrimental effects from pollutants, even at low concentrations, due to reduced immunological defenses and multiple underlying chronic diseases. This cross-sectional study explored environmental variables and buildings characteristics in 22 elderly care centers (ECC) out of a total of 58 institutions in Porto, Portugal.engIndoor EnvironmentRespiratory HealthRespiratory DiseasesOlder PeopleElderly Care CentersPortoPortugalAr e Saúde Ocupacionallecture
