Latent Classes of Sleep Problems and Subjective Cognitive Decline Among Middle-Aged and Older Adults in the United States

Previous studies have linked sleep problems to subjective cognitive decline (SCD) using a variable-centered approach (e.g., adding sleep symptoms to form a score); however, sleep problems may cluster differently between individuals. Thus, employing a person-centered approach, we aimed to: 1) identify profiles of self-reported sleep problems among U.S. middle-aged and older adults; 2) examine the cross-sectional association between these classes and SCD.
