This brief from the Institute for Children, Poverty, and Homelessness (ICPH) presents three key findings from the Youth Risk Behavior Survey (YRBS) related to asthma and students experiencing homelessness. First, homeless students report higher rates of asthma compared with their housed peers across all racial and ethnic groups and locations (i.e., urban, suburban, and rural). Second, homeless students are three times as likely to be unsure of whether they have asthma. This disparity in diagnoses rates inhibits homeless students from managing their asthma. Third, once diagnosed, homeless students are less likely to have a school health center to help monitor their treatment and reduce missed school days and emergency room visits due to asthma attacks.
