Abstract
We aim to investigate factors which might affect the sleep of medical students, and how they currently manage their sleep.
An online survey was sent to medical students at the University of Otago.
After adjusting for gender, ethnicity and age, depressive symptoms (
: odds ratio (OR) = 6.3;
: OR = 18.1;
: OR = 15.6), and sleep hygiene (OR = 1.07) were associated with insomnia symptoms. Commonly endorsed strategies for sleep management by students were undertaking regular exercise (80.1%), having consistent sleep-wake time (71.3%), and limiting caffeine intake (70.3%). Few were willing to see a clinician (23.4%) or take medication (22.3%). Participants with insomnia symptoms were more likely to prefer limiting their alcohol intake (OR = 1.8), limiting daytime naps (OR = 1.5), seeing clinicians (OR = 1.9), and taking sleep medication (OR = 4.0), but less likely to prefer avoiding intense work (OR = .71) or minimizing using electronics (OR = .60) close to bedtime than those without insomnia symptoms. High sleep self-efficacy was associated with lower odds for having insomnia symptoms (OR = .74 (.70, .77)).
Increased awareness and greater resources are needed to support the sleep health of medical students.
