The study used data from the third follow-up of the Respiratory Health in Northern Europe study (RHINE); questionnaires were used to gather the data, including asthma status, asthma-like symptoms, other respiratory symptoms, and parental TB and asthma status.
The results revealed that offspring with a history of parental TB faced a higher risk of developing asthma and respiratory symptoms compared to those without parental TB. Specifically, parental TB was significantly associated with allergic asthma in offspring. However, no significant association was observed between parental TB and asthma without allergies. The study considered sex-specific patterns and found that associations between parental TB and asthmatic conditions were somewhat stronger in female offspring. Find the full article in Frontiers.
