A Retrospective Study Examining Self-Reported Physical Activity Levels Among Asthma Patients Using the Behavioural Risk Factor Surveillance System (BRFSS) Database.

Introduction: Regular physical activity benefits respiratory health by reducing the risk of developing asthma. This is achieved by reducing bronchial hyperresponsiveness and preventing lung function decline.

Aim: The objective of the study is to assess the prevalence of self-reported physical activity among asthma patients in the United States in 2021, based on demographic, socioeconomic, and healthcare access variables.
