Sleep quality, purpose in life, and health related quality of life among people living with HIV in Nigeria

Abstract

Background

Sleep has been linked to multiple health outcomes. We aim to determine the relationship between sleep quality, purpose in life, and HRQoL among PLHIV.

Methods

We conducted a cross-sectional study among 401 PLHIV in the HIV clinic using a structured questionnaire that included their demographics, Pittsburgh Sleep Quality Index (PSQI), Ryff's Scales of Psychological Well-Being, and Veterans RAND 12-item Health Survey (VR-12).

Results

Ninety-two [22.9%] were classified as having poor sleep quality. Poor sleepers had significantly lower scores in the physical component [48.0 (9.5) vs. 51.2 (7.1), p = .014] and mental component 44.7 (10.5) vs. 52.1 (9.8), p < .001 in HRQoL as compared to good sleepers. Purpose in life moderates the effect of sleep quality on the physical component of HRQoL, p_interaction = .003.

Conclusion

Assessing sleep quality and purpose in life routinely among HIV-infected patients may impact the overall wellbeing of PLHIV.
