Abstract

Background Sleep deficits caused by the overuse of digital technology is observed among medical students. Due to the coronavirus disease 2019 (COVID-19) pandemic, an emergency remote teaching method was put into practice, which may have resulted in changes in the sleep-wake cycle. The balance between the influences of external and internal synchronizers can be affected by sudden alterations in daily life, including changes in nightly habits and sleep quality, which can lead to increased levels of anxiety and reduced functional performance, for example.

Objective To understand the relationship between the use of digital technology, changes in the circadian cycle, and academic performance during the pandemic.

Methods The present is an analytical, cross-sectional, observational study in which a sample of 123 medical students filled out an online questionnaire on self-perception regarding sleep quality and academic performance before and during the pandemic.

Results Assessing changes in sleep quality and productivity, the study revealed that 100% of the students made continuous use of screens before bedtime. Thus, during the period of social distancing and remote classes, 77.2% of the students reported “poor” or “very poor academic performance, which was probably related to the fact that 65.9% of these students were unable to maintain their productivity due to daytime sleepiness.

Conclusions The prolonged use of screens was associated with poor sleep quality and changes in academic performance, with significant psychological impact. Thus, it is worth emphasizing the importance of sleep hygiene in light of the new forms of teaching implemented during the COVID-19 pandemic.

Resumo

Introdução Observa-se um déficit de sono ocasionado pelo uso excessivo de tecnologias digitais entre estudantes de medicina. Em face da pandemia da doença do coronavírus 2019 (coronavirus disease 2019, COVID-19, em inglês), um método de ensino à distância foi adotado, e pode ter acarretado mudanças no ciclo de sono e vigília. O equilíbrio entre as influências dos sincronizadores externos e internos pode ser afetado por mudanças bruscas na vida diária, isto inclui alterações nos hábitos noturnos e na qualidade do sono, que podem causar aumento dos níveis de ansiedade e redução do desempenho funcional.

Objetivo Compreender a relação entre o uso de tecnologias digitais, alterações no ciclo circadiano, e desempenho acadêmico durante a pandemia.

Métodos Trata-se de um estudo observacional, analítico e transversal, no qual uma amostra de 123 estudantes de medicina responderam a um questionário online sobre a autopercepção referente à qualidade do sono e ao desempenho acadêmico antes e durante a pandemia.

Resultados Com a avaliação das alterações na qualidade do sono e na produtividade, o estudo revelou que 100% dos alunos faziam uso contínuo de telas antes do horário de dormir. Assim, durante o período de distanciamento social e aulas remotas, 77,2% dos alunos relataram que o desempenho acadêmico era “ruim” ou “péssimo”, o que provavelmente estava relacionado ao fato de que 65,9% desses alunos que não conseguiram manter sua produtividade por conta de sonolência diurna.

Conclusões O uso de telas por tempo prolongado foi associado a mudanças relacionadas à baixa qualidade do sono e a mudanças no desempenho acadêmico, com impacto psicológico significativo. Assim, vale ressaltar a importância da higiene do sono diante das novas formas de ensino implantadas durante a pandemia da COVID-19.
