Sleep habits and the risk of physical, psychological and cognitive multimorbidities: a national prospective cohort study

Background

Physical, psychological, and cognitive multimorbidity (PPC-MM), defined as the coexistence of conditions in at least two domains of physical conditions, depressive symptoms, and cognitive impairment, poses a major challenge to healthy aging. However, its potential risk factors remain unclear. As a key component of health, sleep habits are closely associated with various chronic conditions. This study aimed to investigate the longitudinal associations between sleep habits (night-time sleep duration, nap duration, and sleep quality) and the occurrence and progression of PPC-MM.
