Mental health and quality of life across 6 years of medical training: A year-by-year analysis.

BACKGROUND: Despite growing evidence on medical students' mental health deterioration, studies have primarily used short follow-up periods and not followed the students throughout their medical training.

OBJECTIVE: To assess mental health (stress, anxiety, and depression) and quality of life changes throughout their medical program, we followed up with the same cohort of students for 6 years.

METHODS: This longitudinal prospective study followed up with the same group of medical students at a Brazilian public medical school from 2014 to 2020. The study analyzed sociodemographic data, mental health (including depression, anxiety, and stress [DASS-21]), quality of life (WHOQOL-BREF), satisfaction from studying to be a physician, and happiness with life. General linear mixed models were used for the analyses.

RESULTS: The cohort included 80 Brazilian medical students (63.7% women; mean age = 19.6 years [ SD  = 2.21]). A high prevalence of depressive symptoms, anxiety, and stress was found throughout medical training, with more than 50% of students having significant symptoms. Mental health, happiness, and quality of life levels tended to be better in the first and last semesters, being worse in the middle of the program. However, satisfaction from studying to become a doctor decreased in the second semester, remained low throughout the program, and never returned to baseline levels.

CONCLUSION: Mental health and quality of life levels remained high throughout the medical program, with better levels in the first and last semesters and falling in the middle of the program. These data can help managers and educators understand how psychological distress affects medical students.
