Abstract
Few studies have examined the effects of self-managed lifestyle behavioral adjustment on cognitive status. This study aimed to explore the association between self-managed behavioral changes and transitions in cognitive status. The Hubei Memory and Aging Cohort Study was a prospective cohort study conducted from 2018-2023 in rural and urban areas. Home-dwelling adults aged ≥65 years completed neuropsychological, lifestyle, clinical, and cognitive assessments. The Cox regressions and cubic splines were used to assess the risk of incident cognitive impairment, and latent class analysis was used to group participants based on behavioral patterns and assess transitions in cognitive status. Among 2477 participants with a mean of 2.02 (SD, 1.25) years of follow-up were included in the study. Participants with low and intermediate compared with high baseline behavioral risk exhibited a reduced risk of incident cognitive impairment. At follow-up, those who maintained stable healthy behaviors or positively adjusted them had a 54% (HR, 0.46 [95% CI, 0.34-0.62]) and 84% (0.16 [0.07-0.35]) lower risk of developing cognitive impairment, respectively, compared with those who maintained unhealthy behaviors. The standard and reinforced behavioral adjustment patterns exhibited a 37% (0.63 [0.22-1.79]) and 77% (0.23 [0.05-0.97]) reduction in the risk of incident cognitive impairment, respectively, compared with the basic pattern. Optimal cognitive gains were attributed to positive adjustments in social networks, physical exercise, cognitive activity, and sleep health. Older adults who maintained healthy behaviors or positively adjusted their unhealthy behaviors exhibited a reduced risk of incident cognitive impairment. Positive behavior modification brought greater cognitive improvement to all participants and more pronounced effects for those with dementia.
期刊介绍：
Psychiatry has suffered tremendously by the limited translational pipeline. Nobel laureate Julius Axelrod''s discovery in 1961 of monoamine reuptake by pre-synaptic neurons still forms the basis of contemporary antidepressant treatment. There is a grievous gap between the explosion of knowledge in neuroscience and conceptually novel treatments for our patients. Translational Psychiatry bridges this gap by fostering and highlighting the pathway from discovery to clinical applications, healthcare and global health. We view translation broadly as the full spectrum of work that marks the pathway from discovery to global health, inclusive. The steps of translation that are within the scope of Translational Psychiatry include (i) fundamental discovery, (ii) bench to bedside, (iii) bedside to clinical applications (clinical trials), (iv) translation to policy and health care guidelines, (v) assessment of health policy and usage, and (vi) global health. All areas of medical research, including — but not restricted to — molecular biology, genetics, pharmacology, imaging and epidemiology are welcome as they contribute to enhance the field of translational psychiatry.
