Assessment of depression and suicidal behaviour among medical students in Portugal

Abstract

ObjectivesTo examine depression and suicidal behaviour and associated factors in a sample of medical students in Portugal. MethodsWe conducted a cross-sectional study design of 456 native Portuguese medical students from the 4th and 5th year at the University of Lisbon. Participants answered a self-report survey including questions on demographic and clinical variables. Statistical analyses were conducted using the chi-square test, with a Monte Carlo simulation when appropriate. ResultsDepression among medical students was 6.1% (n=28) and suicidal behaviour 3.9% (n=18). Higher depression scores were noted in female medical students (χ2=4.870,df=2,p=0.027), students who lived alone (χ2=8.491,df=3,p=0.037), those with poor physical health (χ2=48.269,df=2,p<0.001), with poor economic status (χ2=8.579,df=2,p=0.014), students with a psychiatric diagnosis (χ2=44.846,df=1,p=0.009), students with a family history of psychiatric disorders (χ2=5.284,df=1,p=0.022) and students with high levels of anxiety (χ2=104.8, df=3, p<0.001). Depression scores were also higher in students with suicidal ideation (χ2=85.0,df=1,p<0.001), suicidal plan (χ2=47.9,df=1,p<0.001) and suicidal attempt (χ2=19.2,df=1,p<0.001). Suicidal behaviour was higher in medical students who lived alone (χ2=16.936,df=3,p=0.001), who had poor physical health (χ2=18,929,df=2,p=0.001), poor economic status (χ2=9.181,df=2,p=0.01), who are/were in psychopharmacology treatment (χ2=30.108,df =1,p<0.001), and who had high alcohol use (χ2=7.547,df=2,p=0.023), severe depression (χ2=88.875,df=3,p<0.001) and high anxiety levels (χ2=50.343,df=3,p<0.001). The results also revealed that there were no differences between students in the 4th and 5th years of medical school regarding rate of depression and suicidal behaviour.ConclusionsSince depression and suicidal behaviour are mental health problems affecting a significant proportion of medical students, medical schools should implement programs that promote mental health wellness, physical health and economic status between other factors.

Alcohol consumption and suicide risk in medical internship: A Peruvian multicentric study

“…We found a strong positive association between risk for alcohol abuse and suicide risk. Similar results have been seen in previous studies conducted both in medical students and in college students in general . To begin, we can propose three possible basic explanations.…”

Subjective well-being, religiosity and anxiety: a cross-sectional study applied to a sample of Brazilian medical students

“…1,36,[45][46][47][48] The psychiatric literature shows that women present the highest prevalence of depressive and anxiety disorders. 46,49,50 These disorders are linked to the presence of negative emotions and, along with high stress levels, were also more prevalent among female medical students in most studies assessing similar populations, 23,24,45,51,52 but not in all of them. 53 The present study corroborates such a consensus, since it showed that individuals belonging to the female gender presented more negative emotions and less positive emotions.…”

Prevalence of symptoms of depression among the dental undergraduates, Karachi, Pakistan

“…[3] However, it is more prevalent among medical students compared to the general population, the prevalence of depression ranged from 2.9% to 38.2% of medical students; however, the female students predominantly undergraduates who are in their initial medical studies have more susceptibility. [4] Dentistry in medical schools and colleges is recognized in providing the most stressful environment which often exerts a negative impact on the academic performance as well as on the psychological well-being of the students. [5,6] Education is not only providing the knowledge or building the skills but also to develop a better version of the students and transforming them into excellent and market compatible individuals.…”
