Finally, in our study, the association between clinically significant depressive symptoms and life events (both number and severity) was statistically significant irrespective of academic year of study (all chi-square values < 0.05, results not shown in detail). As shown in Tables 6 and 7, while in the univariate analyses a higher prevalence of clinically significant depressive symptoms was observed amongst sophomore students compared to freshmen (OR = 1.37, p = 0.041), the association with year of study did not persist after controlling for life events and other socio-demographic variables in multivariable models.
