Prevalence of health-related behaviours and associated factors in university students in Ireland: a 4-year repeated cross-sectional study.

Background: Transitioning to higher education (HE) has been highlighted as a critical time to embed positive health-related behaviours (HRBs). However, there has been a long-standing association between student life and risk-taking. This study aimed to (1) identify the prevalence of HRBs over time in cohorts of HE students in Ireland, (2) establish an overall health index and analyse the health-related status of HE students and associated factors based on this index and (3) explore student perspectives towards public health interventions.
