Abstract

Background

The interrelationship of stress and sleep disorders has long been established with physical activity (PA) proven effective in their management. Academic staff in medical schools may face heightened stress levels when compared with staff in other disciplines as a result of the rigorous academic environment in medical schools, in addition to other possible work stressors. This study aimed to investigate the levels of stress, sleep disorders, and PA among academic staff at the medical school of Nnamdi Azikiwe University, Awka, Nigeria, and to determine the relationship between these variables.

Methods

This cross-sectional study consecutively recruited 92 adult lecturers at the study site. Data were collected using the Short Form of International Physical Activity Questionnaire (IPAQ-SF), Pittsburgh Quality of Sleep Index (PSQI), and the Health and Safety Work-Related Stress Questionnaire. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 26. The Spearman's rank correlation coefficient was used to assess the association between variables at a significance level of 0.05.

Results

The mean age of the participants was 40.00 ± 7.34 years. The mean score for work-related stress, sleep quality, and PA was 66.09 ± 6.58, 7.84 ± 3.48 (poor quality), and 1219.34 ± 827.83 (moderate PA), respectively. There was a significant positive correlation between work-related stress and PA levels (ρ = 0.22, p = 0.03). Also, there was no significant correlation between sleep quality and work-related stress (ρ = −0.16, p = 0.11) and between work-related stress and sleep quality (ρ = 0.19, p = 0.06).

Conclusion

In conclusion, high concerns of work stress, poor sleep quality, and moderate PA were observed among the study participants. Targeted interventions to promote PA, improve sleep hygiene practices, and alleviate work-related stress among academic staff are recommended.

尼日利亚一所医学院学术人员工作压力、睡眠质量和身体活动的相关性：一项横断面研究

应激与睡眠障碍之间的相互关系早已被确立，体育活动（PA）已被证明是有效的治疗方法。除了其他可能的工作压力因素外，医学院的学术人员与其他学科的工作人员相比，可能面临更大的压力。本研究旨在调查尼日利亚Awka Nnamdi Azikiwe大学医学院学术人员的压力、睡眠障碍和PA水平，并确定这些变量之间的关系。方法本横断面研究在研究现场连续招募92名成人讲师。数据采用国际体育活动简易问卷（IPAQ-SF）、匹兹堡睡眠质量指数（PSQI）和健康与安全工作相关压力问卷收集。数据分析使用社会科学统计软件包（SPSS）版本26。采用Spearman等级相关系数评价变量间的相关性，显著性水平为0.05。结果患者平均年龄40.00±7.34岁。工作压力、睡眠质量、睡眠质量的平均得分分别为66.09±6.58分（差）、7.84±3.48分（中）、1219.34±827.83分（中）。工作压力与PA水平呈显著正相关（ρ = 0.22, p = 0.03）。此外，睡眠质量与工作压力之间无显著相关性（ρ = - 0.16, p = 0.11），工作压力与睡眠质量之间无显著相关性（ρ = 0.19, p = 0.06）。结论研究对象对工作压力的关注程度较高，睡眠质量较差，PA程度中等。建议有针对性的干预措施，以促进PA，改善睡眠卫生习惯，减轻学术人员的工作压力。
