Factors associated with health-related quality of life among Belgrade University students.

Purpose: The aims of the study were to evaluate health-related quality of life (HRQoL) among students of University of Belgrade (Serbia) and to identify factors that might have associated with their HRQoL including relationship with depression.

Methods: Between April and June, 2009, 1624 students were enrolled in the cross-sectional study. HRQoL was assessed by using SF-36 questionnaire and general depressive status by Beck Depression Inventory (BDI). In statistical analysis, ANOVA (Bonferroni adjustment), χ(2) test, and correlation analysis were performed.

Results: In our study, the highest SF-36 scale score was obtained for Physical Functioning. All SF-36 domains significantly (P < 0.01) negatively correlated with BDI. Students of medical sciences had the lowest scores in almost all SF-36 domains. Students who lived with parents had statistically significantly higher scores of majority of SF-36 domains. The total SF-36 score significantly correlated with average monthly family income (P = 0.002). Smokers and non-smokers significantly differed in the total SF-36 score (P = 0.001). Based on the comparison across the physical activity categories, there is a clear pattern of differences in the total SF-36 scores (P = 0.001).

Conclusion: Our findings indicate that multiple factors are adversely associated with students' HRQoL. Appropriate health education programs to target modifiable risk factors may improve students' HRQoL.
