Puerto Rican Black Latinx Populations in the US Have Higher Risk of Emergency Department Asthma Visits than Other Black Subpopulations 

A study in the November 2023 edition of The Journal of Allergy and Clinical Immunology examines asthma morbidity rates across adults in Black ethnic subpopulations. Researchers recruited adults across the United States and Puerto Rico and asked them to self-identify their ethnicity and report asthma exacerbations requiring corticosteroids, emergency department and urgent care visits, and hospitalizations. They found multiethnic Black participants, “specifically Puerto Rican Black Latinx adults, have higher risk” of emergency department and urgent care visits as well as corticosteroid use. They found “no significant differences in hospitalizations among subgroups.”
