Heliyon 2024; 10:e30007. [PMID: 38742083 PMCID: PMC11089308 DOI: 10.1016/j.heliyon.2024.e30007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 04/10/2024] [Accepted: 04/18/2024] [Indexed: 05/16/2024] Open
Abstract
Objective We aimed to (1) identify neuroimaging biomarkers of distinguishing motoric cognitive risk syndrome (MCRS) risk among older Chinese adults with cerebral small vessel disease (CSVD) and (2) detect differences in gait parameters and neuroimaging biomarkers between CSVD individual with and without MCRS, especially during dual-task walking (DTW). Methods We enrolled 126 inpatients with CSVD who were divided into two groups according to MCRS status. Data on basic parameters, variability, asymmetry, and coordination were collected during single-task walking (STW) and DTW. Neuroimaging features (white matter hyperintensities, lacunes, and microbleeds) and total disease burden were calculated. Analysis of variance and logistic regression analyses were applied to assess the role of STW, DTW, and neuroimaging biomarkers in MCRS. Results In total, 126 consecutive inpatients with CSVD were included (84 and 42 patients were classified as MCRS-negative and MCRS-positive, respectively). The MCRS-positive group showed poorer performance for nearly all gait parameters compared with the MCRS-negative group during cognitive DTW. Meanwhile, all gait parameters except asymmetry were assessed in participants with MCRS for significant deterioration during cognitive DTW compared with that during STW. However, only basic parameters differed between STW and cognitive DTW in participants without MCRS. A significant independent association between total CSVD scores and MCRS was also detected. Conclusions For CSVD patients, with higher total CSVD burden rather than any single neuroimaging marker, was linked to a greater risk of MCRS. In addition, CSVD individuals with MCRS had higher variability and phase coordination index (PCI), especially in cognitive DTW. Thus, they should concentrate more on their gait variability or coordination and reduce secondary task loads while walking in daily life, especially in cognitive secondary tasks.

Chang H, Zhao Y. Longitudinal trajectories of handgrip strength and their association with motoric cognitive risk syndrome in older adults. Arch Gerontol Geriatr 2024; 120:105334. [PMID: 38382231 DOI: 10.1016/j.archger.2024.105334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 01/09/2024] [Accepted: 01/14/2024] [Indexed: 02/23/2024]
Abstract
BACKGROUND To identify heterogeneous developmental trajectories of handgrip strength (HGS) in Chinese older adults and to explore the relationship between different developmental trajectories and motoric cognitive risk syndrome (MCR). METHODS We used three waves of longitudinal data from the China Health and Retirement Longitudinal Study from 2011 to 2015, which involved 3773 older adults. Growth mixture modeling (GMM) was used to estimate trajectory classes for HGS, followed by binary logistic regression to explore the association between trajectory classes and MCR. RESULTS GMM analyses extracted four distinct trajectories of HGS: low level-declining group (16.0 %), upper middle level group (30.9 %), high level-steady group (9.5 %), and lower middle level group (43.6 %). In addition, we found that even after adjusting for important covariates, the odds of MCR prevalence were lower in the medium level-high group, high level-steady group, and medium level-low group compared with the low level-declining group. CONCLUSION Appreciable heterogeneity in HGS among older people in China was revealed. Only 9.5 % of older people with HGS in the high level-steady group. And poorer grip strength levels mean a higher risk of MCR. Therefore, interventions should be taken to maintain muscle mass and thus prevent MCR in older adults.

Abstract
BACKGROUND Motor cognitive risk syndrome (MCR) represents a critical pre-dementia and disability state characterized by a combination of objectively measured slow walking speed and subjective memory complaints (SMCs). This study aims to identify risk factors for MCR and investigate the relationship between plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) and MCR among Chinese community-dwelling elderly populations. METHODS A total of 1312 participants were involved in this study based on the data of the Rugao Longevity and Aging Study (RuLAS). The MCR was characterized by SMCs and slow walking speed. The SCCs were defined as a positive answer to the question 'Do you feel you have more problems with memory than most?' in a 15-item Geriatric Depression Scale. Slow walking speed was determined by one standard deviation or more below the mean value of the patient's age and gender group. The plasma of 8-OHdG were measured by a technician in the biochemistry laboratory of the Rugao People's Hospital during the morning of the survey. RESULTS The prevalence of MCR was found to be 7.9%. After adjusting for covariates, significant associations with MCR were observed in older age (OR 1.057; p = 0.018), history of cerebrovascular disease (OR 2.155; p = 0.010), and elevated 8-OHdG levels (OR 1.007; p = 0.003). CONCLUSIONS This study indicated the elevated plasma 8-OHdG is significantly associated with increased MCR risk in the elderly, suggesting its potential as a biomarker for early detection and intervention in MCR. This finding underscores the importance of monitoring oxidative DNA damage markers in predicting cognitive and motor function declines, offering new avenues for research and preventive strategies in aging populations.

Abstract
PURPOSE To systematically review the prevalence of motoric cognitive risk syndrome (MCR) among community-dwelling older adults and provide evidence-based support for policymakers planning health and social care policies. METHOD Web of Science, PubMed, and Cochrane Library databases were searched for cross-sectional, prospective cohort, or population-based longitudinal studies of community-dwelling older adults aged ≥60 years with MCR from inception of the database through December 18, 2021. RESULTS Seventeen studies were included. Pooled prevalence of MCR was found to be 10% (95% confidence interval [8%, 12%], I2 = 98.4%). Results of a subgroup analysis revealed a combined prevalence of MCR of 8.2% in males and 9.2% in females. Pooled prevalence of MCR was 9.7% in Asia and 10.2% in other regions. CONCLUSION Prevalence of MCR in community-dwelling older adults is high. Our research may improve the epidemiological understanding of MCR, draw attention to older adults with MCR, and thus promote research of MCR and the formulation of relevant public health policies. With early identification and intervention of MCR, cognitive function can be improved, and the onset of dementia can be delayed or prevented. [Journal of Gerontological Nursing, 50(4), 16-24.].

Abstract
OBJECTIVES Motoric cognitive risk syndrome (MCR), a pre-dementia syndrome, is characterized by slow gait and subjective cognitive complaints among older adults. This study assessed the relationship between multimorbidity, its patterns, and MCR. METHODS Data for this study were obtained from three waves (2011, 2013, and 2015) of the China Health and Retirement Longitudinal Study. Participants who were aged 60 years and older and had complete data at baseline as well as complete data about MCR at follow-up were selected. Patients without MCR at baseline were selected for further analyses. Longitudinal associations between multimorbidity, its patterns, and MCR were examined using a Cox proportional hazards model. Multimorbidity patterns were classified using latent class analysis. RESULTS A total of 4923 respondents were included at baseline, 43.47% of whom had multimorbidity. Additionally, the prevalence of MCR at baseline was 12.61%. After adjusting for covariates, multimorbidity was positively associated with MCR (hazard ratio [HR] = 1.33, 95% confidence interval [CI] = 1.06-1.68). A higher number of multimorbidity was also significantly associated with an increased risk of developing MCR (HR = 1.10, 95% CI = 1.02-1.19). Three multimorbidity patterns were selected: relatively healthy pattern, respiratory pattern, and cardiovascular pattern. Older adults with the cardiovascular pattern were 1.57 times more likely to develop MCR than those with the relatively healthy pattern (HR = 1.57, 95% CI = 1.16-2.13). There was no significant difference between the relatively healthy pattern and the respiratory pattern (HR = 1.31, 95% CI = 0.91-1.92). CONCLUSIONS MCR is highly prevalent among older Chinese adults. MCR may be exacerbated by multimorbidity. For older adults with multimorbidity (especially cardiovascular multimorbidity), attention should be paid to MCR to achieve early detection, diagnosis, and treatment.

Abstract
BACKGROUND Motoric cognitive risk syndrome (MCR) reduces the quality of life, independence, and social interaction in older adults. Social participation is a potentially modifiable factor that benefits cognitive and mental health. This study explored the mediating roles of social participation between MCR and depression and between MCR and loneliness. METHODS We performed a secondary analysis of data from the 2015-2016 National Social Life, Health, and Aging Project. Slow gait speed and cognitive decline were used to assess MCR. Mediation analysis was applied to two models, both of which used MCR as an exposure and social participation as a mediator. The outcomes were depression and loneliness for each model, respectively. RESULTS Among 1,697 older adults, 196 (11.6%) had MCR. The mediating role of social participation was statistically significant in both models. The indirect effect (β=0.267, p=0.001) of MCR on depression through social participation comprised 11.97% of the total effect (β=2.231, p<0.001). The indirect effect (β=0.098, p=0.001) of MCR on loneliness through social participation was 19.48% of the total effect (β=0.503, p<0.001). CONCLUSION Interventions to increase social participation may reduce depression and loneliness of older adults with MCR.

Abstract
Objective: We investigated the association between dual decline (DD) (loss of memory and gait speed) and the instrumental activities of daily living (IADL) degeneration in older adults. Methods: Data were drawn from the National Social Life, Health, and Aging Project (NSHAP) reflecting changes over 5 years. This study used the NSHAP data set wave 2 (2010-2011, N = 3196) and wave 3 (2015-2016, N = 4377). Results: Data from 1640 participants were retrieved. There were 601 people with DD and 1039 people without-DD. The DD group had a 28.4% (95% CI = 1.013-1.626) greater risk of degrading in IADL than the without-DD group (odds ratio = 1.284, p < .05). Conclusion: Current research can be used when establishing intervention programs or policies that can prevent IADL degradation through simple memory training and walking activities for older adults living in the community.

Abstract
OBJECTIVE Motoric cognitive risk syndrome (MCR) is a newly proposed pre-dementia syndrome. Several studies on the prevalence of MCR have been published; however, the data vary across studies with different epidemiological characteristics. Thus, this study aimed to quantitatively analyse the overall prevalence and associated epidemiological characteristics of MCR among older adults aged ≥ 60 years. METHODS The Cochrane Library, PubMed, Web of Science, CINAHL, Embase, Scopus, PsycInfo, China National Knowledge Infrastructure, Weipu Database, China Biology Medicine disc and Wanfang Database were searched from their inception to January 2022. A modified Newcastle-Ottawa Scale evaluated the risk of bias. Statistical heterogeneity among the included studies was analysed using Cochran's Q and I2 tests. A random effect model calculated pooled prevalence owing to study heterogeneity. Begg's and Egger's tests were used to assess the publication bias. Additionally, subgroup analysis and meta-regression were performed based on different epidemiological characteristics to determine heterogeneity sources. RESULTS Sixty-two studies comprising 187,558 samples were obtained. The pooled MCR prevalence was 9.0% (95% confidence interval: 8.3-9.8). A higher MCR prevalence was observed in females, older adults with a low educational level, depression and cardiovascular risk factors, South American populations, and studies with small sample sizes and cross-section designs. Furthermore, subjective cognitive complaint using scale score and gait speed using instrument gait showed higher MCR prevalence. CONCLUSION MCR is common in older adults, and various epidemiological characteristics influence its prevalence. Thus, preventive measures are required for older adults with higher MCR prevalence.

Abstract
BACKGROUND AND PURPOSE Motoric cognitive risk syndrome (MCR) is a gait-based pre-dementia syndrome associated with risk of dementia. Ascertaining subjective cognitive and motoric complaints may facilitate early and remote identification of individuals with MCR as they are reported to precede and predict objective cognitive and motoric impairments in aging. METHODS The validity of five subjective motoric complaint (SMC) questions and 10 subjective cognitive complaint (SCC) questions was examined for discriminating MCR in 538 non-demented community-dwelling adults. Backward logistic regression was used to identify questions to develop a weighted score to define subjective MCR (MCR-S). Receiver operating characteristic analysis was applied to determine the discriminative ability of MCR-S for the objective MCR (MCR-O) definition based on SCCs and objectively measured gait. Cox proportional hazard models adjusted for potential confounders were used to examine the predictive validity of MCR-S for incident dementia. RESULTS Five subjective complaint questions (three SCC and two SMC) were associated with MCR-O. They were combined to define an MCR-S score (range 0-7) which yielded an area under the curve of 0.89 for discriminating MCR-O from receiver operating characteristic analysis. An optimal cut-score of 2 on the MCR-S score was determined to have good sensitivity (84%) and specificity (82%) for MCR-O. Over a median follow-up of 2.5 years, 29 participants developed dementia. Both MCR-S (adjusted hazard ratio 2.39) and MCR-O at baseline (adjusted hazard ratio 3.16) predicted risk of incident dementia. CONCLUSIONS Subjective MCR had high concordance with MCR-O and can provide a remote screening assessment for MCR-O, which can identify those at high risk for dementia.

Abstract
Background: Motoric cognitive risk (MCR) syndrome is considered to be a pre-dementia syndrome. Although an increasing number of studies have begun to focus on this syndrome, few investigations have been launched in China. This study was performed to examine the prevalence and correlates of MCR in China.Methods: We included 5,725 adults aged over 60 years from China Health and Retirement Longitudinal Study (CHARLS). MCR was defined as the presence of subjective cognitive complaints and a gait speed ≤20th percentile of the weighted population distribution adjusted for sex and height. The associations among selected modifiable associated factors and clinical measures with MCR were examined using multivariate logistic regression analysis. Results: Of the participants, 414 met the criteria for MCR with an overall prevalence 7.29% (95% CI: 6.62–7.96%). MCR was found to be more prevalent among women than men (9.73 vs 4.85%), and more prevalent among participants ≥75 years than those <75 years (7.85 vs 5.23%). After multivariable adjustment, lower or upper extremity functional limitations, activities of daily living (ADL) disabilities, weak grip strength, exhaustion, and history of hypertension were found to be significantly associated with MCR. The multivariate analysis also showed higher levels of cystatin C and C-reactive protein were associated with increased odds for MCR. Conclusions: The present study showed that MCR syndrome is highly prevalent among Chinese community-dwelling older adults, and revealed several factors that were correlated with MCR. Longitudinal studies are warranted to further explore the modifiable risk factors of MCR.

Abstract
BACKGROUND AND PURPOSE Depression can lead to a wide range of adverse health outcomes, including dementia. However, evidence supporting the relationship between depression and motoric cognitive risk syndrome (MCR), a pre-dementia syndrome, remains lacking. This study aimed to examine the association between depression and MCR among community-dwelling Chinese older adults. METHODS Data were taken from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study (CHARLS). Depression was defined by a Center for Epidemiological Studies Depression Scale (CES-D) score ≥10. MCR was defined as subjective cognitive complaints and objective slow gait speed. Multivariate logistic regression analyses were conducted to examine the cross-sectional and longitudinal associations between depression and MCR at baseline and a 4-year follow-up period for the sample population and gender groups. RESULTS The prevalence of MCR was higher in participants with depression than in those without depression at baseline (12.2% vs. 8.9%; p = 0.001). Participants with depression at baseline had a higher 4-year incidence of MCR than those without depression (14.8% vs. 8.7%; p < 0.001). Both cross-sectional analysis (odds ratio [OR] 1.41, 95% confidence interval [CI] 1.13-1.75) and prospective analysis (OR 1.95, 95% CI 1.56-2.44) demonstrated that depression was significantly associated with MCR. These associations were consistent across different gender groups and stronger among female individuals. CONCLUSIONS Depression is an independent risk factor for MCR among community-dwelling Chinese older adults. Special attention should be paid to the care of older people with depression to reduce the occurrence of MCR and even dementia.

Association of Motoric Cognitive Risk Syndrome with Cardiovascular and Noncardiovascular Factors: A Systematic Review and Meta-Analysis. J Am Med Dir Assoc 2021; 23:810-822. [PMID: 34973959 DOI: 10.1016/j.jamda.2021.11.035] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 11/09/2021] [Accepted: 11/27/2021] [Indexed: 12/20/2022]
Abstract
OBJECTIVES Motoric cognitive risk syndrome (MCR) is a recently proposed predementia syndrome characterized by subjective cognitive impairment and slow gait. We aim to assess the cardiovascular and noncardiovascular factors associated with MCR. DESIGN Systematic review and meta-analysis. SETTING AND PARTICIPANTS Studies comparing patients with MCR to those without MCR, and identifying the factors associated with MCR. METHODS We used databases, including PubMed, Cochrane CENTRAL, and Embase, to identify studies evaluating the factors associated with MCR. Mean differences, odds ratios (ORs), risk ratios (RRs), and hazard ratios (HRs) with 95% CIs were calculated using Review Manager. RESULTS Meta-analysis revealed that all cardiovascular factors, including diabetes (21 studies; OR 1.50, 95% CI 1.37, 1.64), hypertension (21 studies; OR 1.20, 95% CI 1.08, 1.33), stroke (16 studies; OR 2.03, 95% CI 1.70, 2.42), heart disease (7 studies; OR 1.45, 95% CI 1.13, 1.86), coronary artery disease (5 studies; OR 1.49, 95% CI 1.16, 1.91), smoking (13 studies; OR 1.28, 95% CI 1.04, 1.58), and obesity (12 studies; OR 1.34, 95% CI 1.13, 1.59) were significantly higher in the MCR than the non-MCR group. Noncardiovascular factors, including age (22 studies; MD = 1.08, 95% CI 0.55, 1.61), education (8 studies; OR 2.04, 95% CI 1.28, 3.25), depression (17 studies; OR 2.19, 95% CI 1.65, 2.91), prior falls (9 studies; OR 1.45, 95% CI 1.17, 1.80), arthritis (6 studies; OR 1.35, 95% CI 1.07, 1.70), polypharmacy (5 studies; OR 1.65, 95% CI 1.07, 2.54), and sedentary lifestyle (11 studies; OR 2.00, 95% CI 1.59, 2.52), were significantly higher in the MCR than in the non-MCR group. Alcohol consumption (6 studies; OR 0.84, 95% CI 0.72, 0.98), however, favored the MCR over the non-MCR group. Additionally, there was no significant association of MCR with gender (22 studies; OR 1.04, 95% CI 0.94, 1.15) and cancer (3 studies; OR 2.39, 95% CI 0.69, 8.28). MCR was also significantly associated with an increased likelihood of incident dementia (5 studies; HR 2.84, 95% CI 1.77, 4.56; P < .001), incident cognitive impairment [2 studies; adjusted hazard ratio (aHR) 1.76, 95% CI 1.44, 2.15], incident falls (4 studies; RR 1.37, 95% CI 1.17, 1.60), and mortality (2 studies; aHR 1.58, 95% CI 1.35, 1.85). CONCLUSIONS AND IMPLICATIONS MCR syndrome was significantly associated with diabetes, hypertension, stroke, obesity, smoking, low education, sedentary lifestyle, and depression. Moreover, MCR significantly increased the risk of incident dementia, cognitive impairment, falls, and mortality.

Abstract
BACKGROUND AND PURPOSE Motoric cognitive risk syndrome (MCR) is characterized by slow walking speed and subjective memory complaints (SMCs). This study investigated the prevalence and potential risk factors of MCR and its association with falls in Chinese community-dwelling older adults. METHODS The analysis was based on data from the Rugao Longevity and Aging Study (RuLAS). MCR was defined as the presence of both SMCs and slow walking speed in participants free of major neurocognitive disorders. SMCs were determined according to a positive answer to the question 'Do you feel you have more problems with memory than most?' in the 15-item Geriatric Depression Scale. Slow walking speed was defined as one standard deviation or more below the mean value for patients' age and sex. Data on falls were derived from a standardized questionnaire. RESULTS The prevalence of SMCs, slow walking speed and MCR in the RuLAS cohort (N = 1592) was 51.9%, 15.6% and 8.3%, respectively. After adjusting for other covariates, an occupation of farming (odds ratio [OR] 2.358, 95% confidence interval [CI] 1.007-5.521, p = 0.048), history of cerebrovascular disease (OR 2.215, 95% CI 1.032-4.752, p = 0.041) and hospitalization (OR 2.008, 95% CI 1.120-3.602, p = 0.019) were risk factors for MCR. Binary logistic regression analysis indicated that the risk of falls was increased by MCR (OR 1.547, 95% CI 1.009-2.371), SMC (OR 1.308, 95% CI 1.003-1.707) and slow walking speed (OR 1.442, 95% CI 1.030-2.017). CONCLUSIONS Early identification of potential risk factors of MCR can prevent the occurrence of adverse health events such as falls in the elderly.

Abstract
BACKGROUND AND PURPOSE Sleep disturbance and cognitive impairment are common and related in the elderly population worldwide. The aim of the present study was to explore the association between sleep disturbance and motoric cognitive risk (MCR) syndrome, which is characterized by subjective cognitive complaints and objective slow gait in older individuals without dementia or any mobility disability in the community-dwelling elderly Chinese population. METHODS We recruited 940 participants aged ≥65 years from November 2016 to March 2017 in the Ningbo Community Study on Aging (NCSA). Self-reported sleep duration and sleep-quality variables, comprehensive geriatric evaluation, as well as indicators for diagnosing MCR syndrome were evaluated in this cross-sectional study. RESULTS Multiple logistic regression analysis showed that a 1-SD increase in night (1.1 h) and 24-h sleep duration (1.3 h) was associated, respectively, with a 21% (95% confidence interval [CI], 1%-47%; p = 0.04) and 30% (95% CI, 3%-64%; p = 0.03) higher odds of having MCR syndrome. Considering sleep duration as a categorical variable, longer night-sleep duration (>8.5 h) was associated with MCR syndrome (OR, 2.03; p = 0.02) compared to shorter night-sleep duration (<8 h). For sleep-quality factors, increasing frequency of trouble falling asleep, waking early or easily, nightmares, and taking sleep drugs were significantly associated with MCR syndrome after adjusting for potential covariables (all p for trend < 0.05), but not for self-perceived sleep quality (p for trend = 0.10). CONCLUSIONS Long sleep duration, poor sleep quality, and taking sleep drugs were associated with higher odds of having MCR syndrome in the community-dwelling elderly Chinese population. Further research is needed to explore the underlying mechanisms.

Abstract
Resumo Objetivo Verificar a prevalência da síndrome de risco cognitivo motor (SRCM) em pessoas idosas do Distrito Federal (DF), Brasil, que frequentaram os serviços de saúde de uma unidade de referência em Geriatria e Gerontologia, comparar os grupos de idosos com e sem a síndrome e investigar os possíveis fatores associados ao desenvolvimento dessa síndrome. Método Trata-se de estudo observacional transversal analítico, desenvolvido com idosos (idade ≥60 anos) com marcha independente e sem alterações cognitivas graves, que possuíam registro de dados sociodemográficos, avaliação cognitiva, capacidade funcional e velocidade de marcha em prontuários datados de 2017 a 2019. A análise dos dados foi expressa em média e desvio-padrão, frequência e percentual, e em odds ratios (OR) com intervalos de confiança de 95%. As comparações entre os grupos com e sem a SRCM foram feitas por meio dos testes: qui-quadrado, U de Mann-Whitney e t de Student. Resultados Não houve diferenças significativas na comparação das variáveis entre os grupos. A prevalência da SRCM na população estudada foi de 24%. Nenhum dos fatores analisados demonstrou associação com a presença da síndrome. Conclusão A prevalência da SRCM na amostra foi de 24% e mostrou-se mais alta na população do DF quando comparada as populações estudadas em outros países. Não houve diferenças entre os grupos de idosos com e sem a síndrome, e os fatores associados não foram encontrados. O rastreio da síndrome é de extrema relevância, pois a partir desses achados pode-se desenvolver mecanismos para a prevenção de demência em idosos.

Abstract
OBJECTIVES Motoric cognitive risk syndrome (MCR) is a newly described pre-dementia syndrome characterized by cognitive complaints and slow gait and is associated with numerous adverse outcomes. Previous studies have indicated an association between C-reactive protein (CRP) and cognitive decline, but no clear relationship between CRP and MCR has been reported. The purpose of the study is to examine the associations between CRP with MCR and MCR subtypes. METHODS Participants were 5,642 adults aged ≥60 years from the China Health and Retirement Longitudinal Study (CHARLS). MCR was defined as cognitive complaints and slow gait speed without dementia or impaired mobility. Two subtypes of MCR were defined by whether memory impairment (MI) was also present, such as MCR-MI and MCR-non-MI. MI was evaluated through the immediate recall and delayed recall in a word recall test during the CHARLS and was defined as 1.0 standard deviation or more below the mean values of the test scores in this cohort. RESULTS Of the participants, 421 (7.46%) met the criteria for MCR. After multivariate adjustment, participants with higher CRP levels had an increased likelihood of MCR (fourth quartile: adjusted odds ratio [OR]=1.44; 95% confidence interval [CI]: 1.06-1.95) compared with those in the first quartile group. The OR for MCR-MI was 2.04 (95% CI: 1.35-3.09) for the highest quartile of CRP compared to the lowest quartile. No significant associations between CRP levels and odds of MCR-non-MI were observed. CONCLUSIONS Higher CRP levels were associated with increased odds of prevalent MCR-MI but not MCR-non-MI among community-dwelling older adults.
