Sleep habits and later physical, psychological and cognitive multimorbidity in Chinese adults aged 45+
In a seven-year cohort of 7,586 Chinese adults aged 45 or older without multimorbidity at baseline, short night-time sleep and poor sleep quality were associated with higher risk of developing physical, psychological and cognitive multimorbidity. These are associations, not proven causes. [1]

The key findings
The cohort included 7,586 participants aged 45 or older with no physical, psychological and cognitive multimorbidity at baseline, followed for seven years. [1]
Over seven years, 3,239 participants (42.6%) developed the multimorbidity; short night-time sleep and poor sleep quality were associated with higher risk. [1]
Frequent restless sleep was associated with a direct transition to conditions in all three domains. [1]

Sleep habits tracked in 7,586 adults aged 45+
The study used data from the China Health and Retirement Longitudinal Study and included 7,586 participants aged 45 or older. All had no physical, psychological and cognitive multimorbidity at baseline and reported their own sleep habits: night-time sleep duration, nap duration and sleep quality. The researchers followed them for seven years and used statistical models to relate sleep habits to the first occurrence and the progression of this multimorbidity.

Short sleep and restless sleep linked to multimorbidity
Over the seven years, 3,239 participants (42.6%) developed the multimorbidity. Short night-time sleep and frequent restless sleep were associated with a higher risk of new cases. Frequent restless sleep was also linked to a direct transition to conditions in all three domains, while some sleep patterns were linked to transitions to two-domain comorbidity. The authors describe a joint adverse association and call sleep disturbances possible early indicators, not causes.

Self-reported sleep, observational design, abstract only
Sleep habits were self-reported, and the design was an observational prospective cohort, so the links do not establish that sleep habits cause multimorbidity. The available text is an abstract; the full text was not reviewed, so details such as how sleep was measured and how confounders were handled are not confirmed here. The findings concern adults aged 45 or older in China and may not apply elsewhere.

How to interpret this
Abstract only; the full text was not reviewed. Sleep habits were self-reported in an observational cohort, so associations do not show causation, and measurement and confounder details are not confirmed here.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
