Effects of a health education intervention on knowledge and attitudes towards chronic non-communicable diseases among undergraduate students in Jordan.

There was a significant improvement in the overall knowledge (Cohen's d effect size (d) = 1.08) and attitudes (d = 0.62) among all the students, regardless of gender. The overall knowledge and attitudes scores were significantly higher among females in the pre-test, but the differences in their overall scores became insignificant in the post-test. Education on specific topics was effective in improving university students' knowledge and attitudes about health-promoting behaviours, thereby preventing CNCDs. It is important to incorporate health promotion education regarding CNCDs into university curricula using innovative approaches to enhance healthy behaviours in young adults.
