Quality of Sleep, Life Quality, and Related Factors in the Middle-Aged and Elderly Population of South Delhi: A Cross-Sectional Survey

AbstractObjective:This study aims to evaluate the quality of sleep and life among middle-aged and elderly individuals, and analyze their interrelation. Additionally, the study identifies various factors linked to poor sleep quality.Materials and Methods:A cross-sectional survey was conducted on 136 middle-aged and elderly Indian adults. Relatively healthy individuals who were caretakers or relatives of patients visiting the Physiotherapy OPD of Delhi Pharmaceutical Sciences and Research University, New Delhi, Delhi, India, were invited to participate in the study. The Pittsburgh Sleep Quality Index and short form-36 (SF-36) were utilized to measure sleep quality and life quality, respectively.Results:About 74.2% of the participants reported mild to severe insomnia, with an average score of 8.48. The most common irregular sleep domains were sleep disturbances (40%) and daytime dysfunction (67%). The quality of sleep was found to be associated with income, education, presence of comorbid conditions, and exercise habits (p ≤ 0.05). A negative correlation was observed between all eight domains of life quality and poor sleep quality.Conclusion:Insomnia was reported by a large percentage of middle-aged and older Indian participants in the study. Sleep disturbances that interfered with day-to-day functioning were frequent. There was a considerable relationship between health problems, education level, and income on sleep quality. Inadequate sleep was found to have a negative correlation with overall life quality, highlighting the necessity of interventions to enhance well-being in this population.
