Cognitive Reserve Relationship with Physical Performance in Dementia-Free Older Adults: The MIND-China Study
Qiwei Dong, Yuanjing Li, Yiming Song, Yu Zhang, Xiaodong Han, Yifei Ren, Jiafeng Wang, Xiaojuan Han et al.. Journal of Alzheimer's disease reports, 2024-10-01
Topic: Brain imaging, connectivity and assessment
Greater educational attainment and mental activity were associated with higher composite SPPB scores and those of its three subtests (p < 0.05). Skilled occupations were associated with higher SPPB, chair stand, and walking speed scores, while greater social support was associated with higher scores for SPPB and chair stand (p < 0.05). Each 1-point increase in composite CR score (range: -0.77 to 1.03) was linearly associated with a multivariable-adjusted β-coefficient of 0.74 (95% confidence interval (CI): 0.58-0.89) for total SPPB score, 0.16 (0.10-0.22) for balance test, 0.40 (0.32-0.48) for chair stand, and 0.17 (0.12-0.23) for walking speed. The association between higher composite CR and total SPPB scores was more prominent in those≥75 years than those aged 60-74 years (p < 0.01). There was no statistical interaction of composite CR score and sex in physical function. High CR is associated with better physical function, especially among older adults (≥75 years).
Key findings
- Greater educational attainment and mental activity were associated with higher composite SPPB scores and those of its three subtests (p < 0.05).
- Skilled occupations were associated with higher SPPB, chair stand, and walking speed scores, while greater social support was associated with higher scores for SPPB and chair stand (p < 0.05).
- Each 1-point increase in composite CR score (range: -0.77 to 1.03) was linearly associated with a multivariable-adjusted β-coefficient of 0.74 (95% confidence interval (CI): 0.58-0.89) for total SPPB score, 0.16 (0.10-0.22) for balance test, 0.40 (0.32-0.48) for chair stand, and 0.17 (0.12-0.23) for walking speed.
- The association between higher composite CR and total SPPB scores was more prominent in those≥75 years than those aged 60-74 years (p < 0.01).
- There was no statistical interaction of composite CR score and sex in physical function.

How this study scored 61/100
Published in a peer-reviewed journal, and it is a snapshot of people at one point in time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 34 of the 56 points we could judge it on, which is 61 out of 100.
