Self-reported prevalence of sleep disorders among medical and nursing students

Abstract

Abstract Background Sleep disorders are highly prevalent among university students. In particular, the symptoms of sleep disorders are more prevalent among healthcare students. Aims To assess the prevalence of risk factors of insomnia and sleep disorders and to examine the correlations between them among nursing and medical students. We also compared the effects of shift work during internship. Methods The sample was 417 healthcare students; 202 of them were nursing students, and the remaining 215 were medical students. We used a self-administered questionnaire to assess the risk factors for insomnia (i.e. age, BMI, tobacco consumption, physical activity and perceived stress, using the General Health Questionnaire-12). We also used the Sleep and Daytime Habits Questionnaire and Epworth Sleepiness Scale to assess the prevalence of sleep disorders and daytime sleepiness. Results A higher percentage of nursing students than medical students were aged 25 years or older, engaged in inadequate levels of physical activity and consumed tobacco. With the exception of tobacco consumption among nursing students, high scores on the GHQ-12 were the only risk factor associated with daytime and nighttime symptoms and poor sleep quality. There was no significant association between the symptoms of sleep disorders and shift work including night shifts. Conclusions Since sleep disorders are highly prevalent among healthcare students, early detection and management is recommended. This will decrease the risk of harm to students and patients, due to medical mistakes.
