Effects of sleep quality and insomnia severity on metabolic and anthropometric parameters in elderly individuals

Abstract

Purpose: This study aimed to investigate the relationship of sleep quality and insomnia with metabolic/anthropometric parameters in elderly individuals. Materials and Methods: This cross-sectional study was conducted with 474 elderly individuals. Their fasting blood glucose, haemoglobin A1c, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, cortisol, C-reactive protein, weight, waist circumference, waist-to-hip ratio, skeletal muscle mass, body fat mass and body mass index were measured. Their sleep quality was evaluated using the Pittsburgh Sleep Quality Index, and insomnia was assessed using the Insomnia Severity Index. Results: The mean age of the 474 elderly individuals included in the study was 71.02±4.90 years. Poor sleep quality prevalence was found to be 71.1% among the elderly participants and the prevalence of mild to moderate insomnia was 55.1%. The sleep quality score was positively correlated with the postprandial blood glucose level (r=0.121, p
