HIV/AIDS knowledge levels among senior university students: a sociodemographic perspective

Aims: The aim of this study was to assess the knowledge levels of final-year students studying in different faculties of Dicle University regarding HIV/AIDS, to identify differences between faculties, and to determine sociodemographic determinants affecting knowledge levels. Methods: This cross-sectional study was conducted between January 1 and March 1, 2025, in the Faculties of Medicine, Dentistry, Pharmacy, Nursing, Education, Engineering, Veterinary Medicine, Agriculture, and Theology. The study population consisted of 4,406 final-year students, and the sample size was calculated as 354 based on a 50% prevalence, a 5% margin of error, and a 95% confidence interval.

For comparisons between groups, the independent samples t-test was used when parametric assumptions were met, whereas the Mann–Whitney U test was applied when these assumptions were not satisfied. Effect sizes for pairwise comparisons were calculated using Cohen’s d. In addition, multivariable linear regression analysis was performed to identify independent factors associated with the total knowledge score. A p-value of
