Factors affecting quality of life and sleep: examination of sociodemographic and biochemical parameters

Abstract

Objective: To examine the relationship between quality of life and sleep, as well as the sociodemographic and biochemical parameters affecting them. It has been observed that such an exhaustive research has not been done before. Methods: Sociodemographic details were gathered using a specific survey form. To assess the quality of life of the participants, the Quality of Life Scale (SF-36). The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate participants' sleep quality. The gathered data were analyzed using the SPSS-22 statistical software. Results: There were no significant differences in SF-36 and PSQI scores according to gender. However, PSQI and SF-36 scores varied significantly based on marital status, educational status, employment status, family type, chronic disease status, as well as smoking status and vitamin D levels. A negative correlation was found between PSQI and SF-36 scores, indicating that quality of life and sleep quality are positively correlated; as the score on the sleep quality scale increases, sleep quality decreases. Furthermore, it was determined that quality of life and sleep quality improve with higher levels of calcium, glucose, and vitamin D. Conclusion: To enhance individuals' quality of life and sleep, it is important to consider their sociodemographic characteristics and blood biochemistry.
