Prevalence and risk factors for subjective cognitive decline and the correlation with objective cognition among community-dwelling older adults in China: Results from the Hubei memory and aging cohort study.

INTRODUCTION: The prevalence and risk factors for subjective cognitive decline (SCD) and its correlation with objective cognition decline (OCD) among community-dwelling older adults is inconsistent. METHODS: Older adults underwent neuropsychological and clinical evaluations to reach a consensus on diagnoses. RESULTS: This study included 7486 adults without mild cognitive impairment and dementia (mean age: 71.35 years [standard deviation = 5.40]). The sex-, age-, and residence-adjusted SCD prevalence was 58.33% overall (95% confidence interval: 58.29% to 58.37%), with higher rates of 61.25% and 59.87% in rural and female subgroups, respectively. SCD global and OCD language, SCD memory and OCD global, SCD and OCD memory, and SCD and OCD language were negatively correlated in fully adjusted models. Seven health and lifestyle factors were associated with an increased risk for SCD. DISCUSSION: SCD affected 58.33% of older adults and may indicate concurrent OCD, which should prompt the initiation of preventative intervention for dementia. HIGHLIGHTS: SCD affects 58.33% of older adults in China. SCD may indicate concurrent objective cognitive decline. Difficulty finding words and memory impairments may indicate a risk for AD. The presence of SCD may prompt preventative treatment initiation of MCI or dementia. Social network factors may be initial targets for the early prevention of SCD.

Dual-task performance in old adults: cognitive, functional, psychosocial and socio-demographic variables.

BACKGROUND: Dual tasking, or the ability to executing two tasks simultaneously, has been used in recent research to predict cognitive impairments, physical frailty, and has been linked with cognitive frailty in old adults. AIM: This study aimed to determine age-related variables can predict dual-task (DT) performance in the older population. METHODS: A total of 258 healthy community-dwelling participants + 60 years were assessed in relation to their functional capacity, health, well-being, social support and years of education. Performance of a cognitive (Fluency) task and a cognitive-motor (Tracking) task was recorded under single and DT conditions. Multiple linear regression analysis was carried out for each dependent variable, in separate models including cognitive, functional and psychosocial variables. RESULTS: Performance in Fluency in DT conditions was predicted by cognitive variables, whereas performance in Tracking DT conditions was predicted by positive interaction, health status, age and motor variables. DISCUSSION: The findings suggest that a wide range of cognitive, psychological, social, physical and functional variables influence cognitive and motor performance in aging. CONCLUSION: DT methodology is sensitive to different age-related changes and could be related to frailty conditions in aging.

Objective To explore the current status and predictive factors of frailty among community-dwelling old adults.Methods A total of 1 012 community-dwelling older adults aged 65 years and above in Sichuan Province were enrolled and investigated by self-made general condition scale,Tilburg Frailty Indicator (TFI),Short Physical Performance Battery (SPPB),10-item Connor-Davidson Resilience Scale (CD-RISC-10),Mini-Mental State Examination (MMSE) and Geriatric Depression Scale Short-form (GDS-15).Results (1) The prevalence of frailty was 30.73％.(2) There were significant differences in the frailty scores of community-dwelling older adults in terms of gender,education,marital status,living condition,spouse support,children support,family economic conditions,self-perceived health status,number of chronic diseases,body mass index,number of falls in the past year,exercise state and sleep time at night(all P＜0.05).(3) The frailty (3.72±2.88) was significantly positively correlated with depression (2.69± 2.58;r=0.58,P＜0.01),and negatively correlated with the scores of balance ability(3.28± 1.01),walking speed (2.92± 1.05),chair rise test (2.92± 1.27),strength of resilience (13.99±3.57) and MMSE (23.71 ±5.55) (r=-0.33-0.43,P＜0.01).(4) Depression (β=0.416,P＜0.001),the number of chronic diseases (β=0.219,P＜0.001),balance ability (β=-0.166,P＜0.001),spousal support (β=-0.089,P＜0.01),strength of resilience(β =-0.097,P＜0.01),family economic status(β=0.093,P＜0.01) and gender(β=0.082,P＜0.01) significantly influenced frailty,with a combined explanation variance of 45.9％.Conclusions The rate of frailty of community-dwelling old adults is high,which is influenced by physiological,psychological and social factors.Therefore,it is necessary to adopt a comprehensive model of multi-disciplinary cooperation to carry out frailty intervention in community.
