The Association Between Sleep and Quality of Life Among Visitors of Lifestyle Clinics at the Ministry of National Guard-Health Affairs, Western Region, Saudi Arabia.

ABSTRACT

BACKGROUND: Sleep quality significantly impacts health-related quality of life (QoL). However, the link between sleep quality and QoL needs further exploration, especially in the context of Saudi Arabia. OBJECTIVE: To assess the effect of sleep quality on QoL among visitors of lifestyle clinics at the National Guard primary healthcare centers in the Western region of Saudi Arabia in 2023. METHODS: A cross-sectional study was conducted among 369 participants. Data were collected using a questionnaire that addressed sociodemographic characteristics, sleep quality, and perceived QoL. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while QoL was measured using the Short Form-20 (SF-20) QoL scale. Statistical analysis was performed using SPSS (IBM Corp., Armonk, NY). RESULTS: The median age of participants was 38 years, and the median PSQI score was 9, indicating poor sleep quality. Significant differences in sleep quality were found relating to gender and income. Male gender and low-income status were associated with lower sleep quality. The scores for sleep quality varied between 3 and 16, with a median score of 9, while QoL scores ranged from 34 to 92, with a median score of 72. Good sleep quality was found only among 4.9% of the participants and was associated with higher QoL scores. The correlation between sleep quality and QoL was significant, with a correlation coefficient of -0.399 (p-value < 0.001). CONCLUSION: The study identifies a significant correlation between poor sleep quality and lower QoL among visitors of lifestyle clinics in the Western region of Saudi Arabia. These findings suggest the necessity of addressing sleep quality in interventions aimed at improving overall well-being.
