Intraindividual sleep variations; Phisical activity, diet, CVD and Cancer; Early Microbiome and siblings
How much sleeps vary from night-to-night? Age, gender, and racial/ethnic identity all significantly influence how much and how effectively we typically sleep. There is an increase in studying the significance of intraindividual variability (IIV) in sleep from night to night. A recent study compared racial/ethnic, age and gender groups. Younger adults had more diary and actigraphy sleep duration variability. Gender differences were inconsistent. White and non-Hispanic/Latin adults had lower IIV scores for sleep efficiency and duration. The quality of sleep varies greatly from night to night, even among healthy sleepers. Similar to mean sleep, intraindividual variability in sleep may vary depending on demographic factors. Results from this study is hoped to define the normative levels of sleep IIV in healthy sleepers.
