Key Points

To investigate the relationship between second-hand smoke exposure and different asthma endotypes among Puerto Rican youth.
Analyzed asthma endotypes based on exposure to second-hand smoke
Measured airway hyperresponsiveness and immunoglobulin E levels
Used epidemiological data from Puerto Rican youth
Found distinct asthma endotypes significantly associated with prolonged second-hand smoke exposure
Identified increased airway hyperresponsiveness in youth exposed to second-hand smoke
Observed higher levels of immunoglobulin E among adolescents with heavy exposure to second-hand smoke

Implication

Examines asthma endotypes linked to second-hand smoke exposure in Puerto Rican youth, indicating significant health implications.
