Background:
This study investigated the level of knowledge and risk perception related to climate change and its health impacts among a university population in Southern Italy.
Methods:
Data were collected through a paper-based questionnaire administered in classrooms and offices, covering sociodemographic characteristics, climate change knowledge, risk perception, environmental attitudes, and awareness of the "One Health" approach.
Results:
Among 551 participants, 57.2% achieved high knowledge, which was associated with older age, a climate-related academic or professional background, and attendance at the University of Catanzaro. Most respondents (96.3%) recognized the impact of global warming on human health, though 11% believed climate change severity was overstated, a view more common among men and married or separated individuals. Awareness of the "One Health" concept was limited to 41.4%, yet those familiar with it acknowledged its importance in preventing climate-related diseases. Internet and social media were the primary information sources.
Conclusions:
Findings reveal generally high awareness but notable variability across subgroups, highlighting the need for targeted educational interventions that combine scientific knowledge with environmental attitudes to promote effective mitigation and adaptation strategies.
