Sleep plays a crucial role in health, well-being, and academic performance. Despite the recognized importance of good sleep for students, there is a need for a deeper understanding of the sleep problems faced by university students to inform effective campus support services and interventions. This study aimed to evaluate sleep quality among university students by assessing differences in key sleep parameters between sex and age groups.
A cross-sectional study was conducted to assess sleep quality using the validated Pittsburgh Sleep Quality Index among 295 undergraduate students at the University of Cape Coast, Ghana. Demographic characteristics of age and sex were also collected. Data were analyzed using descriptive statistics, Pearson's correlation, and cross-tabulations to compare sleep quality scores between sex and age groups.
The study included 295 undergraduate students aged 20-29 years, of which 53.2 % were male. Overall, 48.5 % of participants exhibited poor sleep quality (PSQI >5). The distribution of global PSQI scores varied by age group, with those aged 25, 27, 28, and 29 reporting higher rates of poor sleep quality. Mean scores on global PSQI scores and other components, including sleep duration and habitual sleep efficiency, were highest among those aged 25 years. Female students were more likely to experience poor sleep quality than male students (51.4 % vs. 45.2 %). Key sleep parameters such as sleep latency, disturbances, and daytime dysfunction showed significant associations with increasing age, although the correlations were weak. Global PSQI scores significantly correlated with both age (r = 0.378, p = 0.001) and sex (r = 0.212, p = 0.001).
This study revealed a high prevalence of poor sleep quality among the respondent, with sleep disturbances and duration disproportionately affecting their sleep quality. These findings underscore the need for universities to prioritize promoting healthy sleep habits and addressing diverse sleep component issues within their student populations.
睡眠在健康、幸福和学业表现中起着至关重要的作用。尽管良好睡眠对学生的重要性已得到认可，但仍需要更深入地了解大学生面临的睡眠问题，以便为有效的校园支持服务和干预措施提供依据。本研究旨在通过评估性别和年龄组之间关键睡眠参数的差异，来评估大学生的睡眠质量。
进行了一项横断面研究，使用经过验证的匹兹堡睡眠质量指数对加纳海岸角大学的295名本科生的睡眠质量进行评估。还收集了年龄和性别的人口统计学特征。使用描述性统计、皮尔逊相关性和交叉表分析数据，以比较性别和年龄组之间的睡眠质量得分。
该研究纳入了295名年龄在20至29岁之间的本科生，其中53.2%为男性。总体而言，48.5%的参与者睡眠质量较差（PSQI>5）。全球PSQI得分的分布因年龄组而异，25岁、27岁、28岁和29岁的参与者报告的睡眠质量差的比例较高。全球PSQI得分以及包括睡眠时间和习惯性睡眠效率在内的其他组成部分的平均得分在25岁的参与者中最高。女学生比男学生更有可能睡眠质量差（51.4%对45.2%）。睡眠潜伏期、干扰和日间功能障碍等关键睡眠参数与年龄增长呈显著相关，尽管相关性较弱。全球PSQI得分与年龄（r=0.378，p=0.001）和性别（r=0.212，p=0.001）均显著相关。
本研究显示，受访者中睡眠质量差的患病率很高，睡眠干扰和时长对他们的睡眠质量影响尤为严重。这些发现强调了大学需要优先促进健康的睡眠习惯，并解决学生群体中各种睡眠组成部分的问题。
