Factors associated with poor academic performance among undergraduate dental students: A cross-sectional study

To evaluate the factors associated with poor academic performance among undergraduate dental students enrolled at a public university in Brazil.

A semi-structured questionnaire addressing the exploratory variables of interest (sociodemographic and economic characteristics, use of medications and drugs, dentistry as the first choice of undergraduate course, and the Pittsburgh Sleep Quality Index) was hosted on Google Forms and shared with all dental students at the Federal University of Pelotas. Academic performance was evaluated based on institutional records, access to which the participants had previously authorized; students with good (average ≥7.0 points) or poor academic performance (average <7.0 points) were considered. Adjusted logistic regressions were performed to verify the association between academic performance and the exploratory variables (p < 0.05).

In total, 244 students were included, of whom 18.8% had poor academic performance. Increased age (OR: 1.34; 95%CI: 1.18-1.52), non-white skin color (OR: 1.34; 95%CI: 1.18-1.52), the use of medications for anxiety and depression (OR: 1.34; 95%CI: 1.18-1.52), and poor sleep quality (OR: 1.34; 95%CI: 1.18-1.52) were factors associated with poor academic performance.

A low prevalence of poor academic performance was observed. Non-white skin color, increased age, use of anxiolytics or antidepressants, and poor or disturbed sleep may reduce dental students' academic performance.
