AI Article Synopsis
- Research indicates that statins have a protective effect on bone health, particularly against osteoporotic fractures in the elderly, but results vary across studies.
- The current study analyzed data from over 365,000 older adults in South Korea, finding that statin use significantly reduced the risk of major osteoporotic fractures, especially vertebral and hip fractures.
- The osteoprotective effects of statins were more pronounced with higher use and among those starting treatment at age 80 or older, suggesting both age and dosage play crucial roles in fracture risk reduction.
Article Abstract
Unlabelled: Previous studies have revealed the protective effects of statins on bone but the association of statins use with osteoporosis-related measurement has shown controversial results. In this study, we found an age, dose andduration-dependent osteoprotective effect of statins in general older population.
Purpose: Previous studies have revealed the protective effects of statins on bone but the association of statins use with osteoporotic fractures has shown controversial results.
Methods: In this study with Korean National Health Insurance Service-Senior cohort database, a total of 365,656 elderly without previous history of osteoporosis and who were started on statin since January 1 2004 were included and observed until December 31 2012. Hazard rations (HR) for major osteoporotic fractures were calculated using the weighted Cox proportional hazards model with inverse-probability of treatment weighting method.
Results: During 6.27 years of follow-up period, 54,959 osteoporotic fractures occurred and the majority of fractures (69.5%) were vertebral fractures. Compared with non-users, statin use was associated with a decreased risk of all outcomes with adjusted HR (95% CI) of 0.77 (0.72-0.83; P < 0.001) for major osteoporotic fractures, 0.49 (0.38-0.62; P < 0.001) for hip fractures, and 0.70 (0.64-0.77; P < 0.001) for vertebral fractures. When outcomes were examined separately by sex, the results were broadly comparable in terms of patterns of risk reduction by statin use. The patients with statin initiated at age ≥ 80 years had the highest risk reduction for most outcomes relative to non-users. Higher cumulative dose of statin was negatively associated with the osteoporotic fracture risk; 0.97 (0.91-1.02) for 30-364 cumulative daily defined dose (cDDD), 0.45 (0.40-0.51) for 365-1,094 cDDD, and 0.22 (0.15-0.33) for ≥ 1,095 cDDD.
Conclusions: Our results showed that statin use was associated with significant reduction in the risk of osteoporotic fractures in general older population.

Background: Poor sleep health is associated with cognitive impairment (CI) in older adults. The cardiopulmonary coupling (CPC) sleep spectrogram, which estimates the sleep state modulated synchronization between heart rate variability and respiration, is an increasingly recognized measure of sleep stability. However, little is known about the longitudinal association between CPC measures of sleep stability and risk of incident CI.

Background: Individuals with dementia frequently exhibit disturbed sleep electroencephalography (EEG) microstructures, including spindles and slow oscillations. We have previously developed a sleep EEG‐based brain age index (BAI), which integrates multiple sleep EEG microstructures and has been associated with prevalent dementia in clinical populations. Here, we aim to determine if BAI is associated with incident cognitive impairment (CI) in a community population of older men, and its discrimination capability as a digital biomarker.

Background: Osteoporosis, a skeletal disorder affecting nearly 20% of the global population, poses a significant health concern, with osteoporotic vertebral body fractures (VBF) representing a common clinical manifestation. The impact of osteoporotic sintering fractures in the thoracolumbar spine on the sagittal lumbar profile is incompletely understood and may lead to the onset of clinical symptoms in previously asymptomatic patients.
Methods: This retrospective single-center study analyzed data from patients presenting with osteoporotic spine fractures between 2017 and 2022.

Unlabelled: Our study investigated trends in osteoporosis management in Xiamen from 2012 to 2021, revealing improvements in screening and treatment, although medication use remained low. Additionally, we identified factors that may influence medication use and emphasized the importance of effective osteoporosis management strategies.
Purpose: The goal of the current study is to explore trends in assessment, diagnosis after fragility fractures, and osteoporosis treatment among hospitalized patients in Xiamen, China, between 2012 and 2021.
