| 摘要 | INTRODUCTION: Healthy sleep may support cognitive health, but the role of weekend catch-up sleep is unclear. METHODS: Among 83,776 dementia-free UK Biobank participants aged >= 50 years, sleep duration was estimated from 7-day accelerometer data (2013-2015). Weekend catch-up sleep was defined as the weekend-weekday sleep duration difference. Cox regression model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause dementia associated with weekend catch-up sleep. RESULTS: During follow-up (median: 8.0 years), 713 participants developed all-cause dementia. Compared with <= 0.5 h, HRs for all-cause dementia across catch-up sleep categories were 0.91 (0.74-1.11) for > 0.5-1 h, 0.64 (0.49-0.86) for > 1-1.5 h, 0.84 (0.60-1.16) for > 1.5-2 h, and 0.83 (0.60-1.16) for > 2 h. The association was stronger among participants with weekday sleep < 8 h (HR: 0.49, 0.29-0.81 for > 1-1.5 h) but non-significant in those with >= 8 h (p-interaction = 0.039). DISCUSSION Moderate weekend catch-up sleep was linked to lower dementia risk, especially among individuals with less weekday sleep. |
