However, their impact on respiratory health is underexplored in the Saudi university context. The aim is to assess the prevalence of e-cigarette use and its association with adverse respiratory symptoms among students at Imam Mohammad Ibn Saud Islamic University (IMSIU) in Riyadh, Saudi Arabia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A cross-sectional online survey was conducted from August to October 2024 among 404 undergraduate students at IMSIU. A validated, bilingual questionnaire (in Arabic and English) was distributed via social media.

E-cigarette use was significantly associated with adverse respiratory symptoms. Bronchitis was reported in 41.7% of nonusers who had abstained in the past 30 days, compared to 16.3% and 12.5% among users who vaped for one to five days and six to 30 days, respectively (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .048).
