Good sleep hygiene plays an important role in human health. Medical students are notorious for insufficient and irregular sleep habits which are linked with students' learning abilities, poor academic performance, and poor interpersonal relationship which predispose them to mental illnesses. However, it has not been studied among medical students in Ethiopia.
This institution-based cross-sectional study was conducted among 576 undergraduate medical students selected by using a stratified sampling technique. Sleep hygiene (SHI) was assessed by a 13-item sleep hygiene questionnaire. Binary logistic regression was used to identify the potential determinants of poor sleep hygiene among undergraduate medical students. Variables with values less than 0.05 were considered statistically significant, and the strength of the association was presented by adjusted odds ratio with 95% C.I.
The prevalence of poor sleep hygiene practice among undergraduate medical students was 48.1% (95% 43.7, 52.1). After adjusting for the possible confounders, being female (AOR = 1.53, 95% CI 1.03, 2.26), having depressive symptoms (AOR = 3.55, 95% CI 2.26, 5.59), with stress symptoms (AOR = 2.41, 95% CI 1.61, 3.60), and having anxiety symptoms (AOR = 2.2, 95% CI 1.42, 3.31) were associated with poor sleep hygiene practice at value < 0.05.
Almost half of the medical students had poor sleep hygiene practice. Routine screening of depressive and stress symptoms and education about sleep hygiene are warranted among medical students.
良好的睡眠卫生对人类健康起着重要作用。医学生因睡眠不足和不规律的睡眠习惯而声名狼藉，这些习惯与学生的学习能力、学业成绩不佳以及人际关系不良有关，使他们易患精神疾病。然而，埃塞俄比亚的医学生中尚未对此进行研究。
本基于机构的横断面研究在采用分层抽样技术选取的576名本科医学生中进行。通过一份包含13个条目的睡眠卫生问卷评估睡眠卫生（SHI）。采用二元逻辑回归确定本科医学生睡眠卫生差的潜在决定因素。P值小于0.05的变量被认为具有统计学意义，关联强度以调整后的优势比及95%置信区间表示。
本科医学生中睡眠卫生习惯差的患病率为48.1%（95% 43.7，52.1）。在对可能的混杂因素进行调整后，女性（优势比 = 1.53，95%置信区间1.03，2.26）、有抑郁症状（优势比 = 3.55，95%置信区间2.26，5.59）、有压力症状（优势比 = 2.41，95%置信区间1.61，3.60）以及有焦虑症状（优势比 = 2.2，95%置信区间1.42，3.31）与睡眠卫生习惯差相关，P值 < 0.05。
几乎一半的医学生睡眠卫生习惯差。有必要对医学生进行抑郁和压力症状的常规筛查以及睡眠卫生教育。
