Sleep health of healthcare workers in Kano, Nigeria

Abstract

Background: The relevance of sleep in the life of a human being cannot be overemphasized in terms of physical and mental well-being. Among several factors that can affect the sleep health of an individual occupation have been found to play a prominent role. The literature is still scanty with regard to sleep studies in our environment.

Aim: This study aims to assess the sleep health of tertiary healthcare workers in Kano Nigeria and find, if any, its determining or related factors.

Material and Methods: This study was cross-sectional questionnairebased survey and involved all consenting staff members of Aminu Kano Teaching Hospital, Kano, Nigeria. The Pittsburgh Sleep Quality Index Questionnaire was used to assess the sleep health of the participants.

Results: The participants’ ages ranged from 18 to 65 years and have a mean age of 38.94 ± 8.07 years. There were 119 (74.4%) males and 41 (25.4%) females with a M:F ratio of 3:1 (χ² = 19.415; P = 0.000). Among the 155 participants who completed all the aspects of the Pittsburgh Sleep Quality Index questionnaires, the overall sleep quality of the study population was found to be significantly poor [good sleepers = 71 (45.8%), poor sleepers = 84 (54.2%), χ² = 116.4; P = 0.000]. Considering the various occupational groups working in the hospital, poor sleep was commonest among the nurses 35 (42.7%). Furthermore, among the nurses, poor sleep was significantly commoner in those on shift work 27 (77.1%) than those not on shift work 8 (22.9%); χ² = 36.2; P = 0.000. Multivariate logistic regression analysis showed that age, sex, and duration in service were not significant predictors of poor sleep quality among the participants [odds ratio (OR) = 1.013, 95% confidence interest (CI) = 0.948–1.084, P = 0.698; OR = 0.691, 95% CI = 0.293–1.631, P = 0.399; and OR = 0.993, 95% CI = 0.932–1.058 P = 0.840, respectively).

Conclusions: Our study found that a significant proportion of healthcare workers and particularly nurses had poor sleep quality. Also, age, sex, and duration in service were not significant predictors of poor sleep quality among the participants.
