[PMID: 38594711 PMCID: PMC11003163 DOI: 10.1186/s13104-024-06766-z] [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: 11/08/2023] [Accepted: 04/03/2024] [Indexed: 04/11/2024] Open
Abstract
BACKGROUND Previous studies have examined relationship between cognitive function and lifestyle; however, the nature of this relationship is expected to vary in diverse cultural and low-income setting where lifestyle practices differ from those in high-income countries. AIM This study aims to investigate the correlation between lifestyle factors and cognitive function among individuals aged 60 years and older in 2021. METHODS This cross-sectional, Community-based study involved 300 older adults from comprehensive urban health centers in Khorramabad, Iran, selected through stratified cluster sampling. Data were collected using the demographic information questionnaire, Mini-Mental State Examination, and Lifestyle Questionnaire. Data management and analysis were performed using SPSS (version 22) and independent t-tests, Pearson's correlation coefficient, ANOVA, and multiple linear regression analysis were used. A p value < 0.05 was considered significant. RESULTS The study included 156 males (52%) and 144 females (48%). Findings revealed a significant correlation between cognitive function and lifestyle (P < 0.001). Multiple linear regression analysis indicated that physical health, environmental health, exercise, accident prevention, and avoidance of medication exerted the most significant positive effect on cognitive function. Conversely, social health exhibited a notable negative influence on cognitive function. (P < 0.001). CONCLUSION The results suggest that specific aspects of lifestyle, such as physical health, accident prevention, and avoidance of medication are associated with cognitive function in older adults. Consequently, lifestyle promotion programs may enhance cognitive function and improve the quality of life among older adults.

Hu J, Ye M, Xi J. Late Life Cognitive Function Trajectory Among the Chinese Oldest-Old Population-A Machine Learning Approach. JOURNAL OF GERONTOLOGICAL SOCIAL WORK 2024:1-21. [PMID: 38590205 DOI: 10.1080/01634372.2024.2339982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 04/03/2024] [Indexed: 04/10/2024]
Abstract
Informed by the biopsychosocial framework, our study uses the Chinese Longitudinal Healthy Longevity Survey (CLHLS) dataset to examine cognitive function trajectories among the oldest-old (80+). Employing K-means clustering, we identified two latent groups: High Stability (HS) and Low Stability (LS). The HS group maintained satisfactory cognitive function, while the LS group exhibited consistently low function. Lasso regression revealed predictive factors, including socioeconomic status, biological conditions, mental health, lifestyle, psychological, and behavioral factors. This data-driven approach sheds light on cognitive aging patterns and informs policies for healthy aging. Our study pioneers non-parametric machine learning methods in this context.

Abstract
Cognitive frailty (CF) is defined as the clinical syndrome of the combination of physical frailty and cognitive impairment, without dementia. Numerous risk factors for CF have been previously identified but this scoping review focusses on the critical need for social engagement and the association with cognition. The focus of this scoping review on the opportunity for social engagement rather than on perception or experience of loneliness. Based on the results of 55 studies were synthesised into four social engagement categories, namely participation, household, network, and habitat. Social engagement is associated with maintaining or improving cognition, particularly through active participation in social roles. Habitat (i.e., rural or urban settings) also influences cognition and the challenge is to enable social participation.

[PMID: 38505741 PMCID: PMC10949544 DOI: 10.1177/23337214241239219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 02/15/2024] [Accepted: 02/27/2024] [Indexed: 03/21/2024] Open
Abstract
Background: As the global population ages, understanding factors that contribute to better cognitive function in older adults becomes crucial. This systematic review delves into the potential relationship between reading the Holy Quran and cognitive function in older adults. Methods: A systematic search was conducted across five electronic databases (PubMed, ScienceDirect, Google Scholar, Tripdatabase, Cochrane) to identify relevant studies that were published between 2004 to December 2023. Inclusion criteria were centered on studies exploring the correlation between reading the Quran and cognitive function in older adults. Results: Five studies meeting the inclusion criteria were included in this systematic review. Notably, four of these studies reported a significant correlation between the intensity or duration of Quranic reading and improved cognitive function in older adults. Discussion: The findings imply a potential positive association between engaging with the Holy Quran and cognitive function among the elderly. This relationship holds promise for potential applications in cognitive health interventions for older adults especially for Muslim patients. Conclusion: This review provides evidence supporting the relationship between reading the Holy Quran and normal cognitive function in older adults. The consistent findings underscore the importance of further research to elucidate underlying mechanisms and consider potential implications for cognitive health interventions.

Abstract
The aim of the paper is to determine the effects of the cognitive reserve on brain tumour patients' cognitive functions and, specifically, if cognitive reserve helps patients cope with the negative effects of brain tumours on their cognitive functions. We retrospectively studied a large sample of around 700 patients, diagnosed with a brain tumour. Each received an MRI brain examination and performed a battery of tests measuring their cognitive abilities before they underwent neurosurgery. To account for the complexity of cognitive reserve, we construct our cognitive reserve proxy by combining three predictors of patients' cognitive performance, namely, patients' education, occupation, and the environment where they live. Our statistical analysis controls for the type, side, site, and size of the lesion, for fluid intelligence quotient, and for age and gender, in order to tease out the effect of cognitive reserve on each of these tests. Clinical neurological variables have the expected effects on cognitive functions. We find a robust positive effect of cognitive reserve on patients' cognitive performance. Moreover, we find that cognitive reserve modulates the effects of the volume of the lesion: the additional negative impact of an increase in the tumour size on patients' performance is less severe for patients with higher cognitive reserve. We also find substantial differences in these effects depending on the cerebral hemisphere where the lesion occurred and on the cognitive function considered. For several of these functions, the positive effect of cognitive reserve is stronger for patients with lesions in the left hemisphere than for patients whose lesions are in the right hemisphere. The development of prevention strategies and personalized rehabilitation interventions will benefit from our contribution to understanding the role of cognitive reserve, in addition to that of neurological variables, as one of the factors determining the patients' individual differences in cognitive performance caused by brain tumours.

Abstract
BACKGROUND Given the unique socioeconomic structures, and the rural/urban differentials in the prevalence of mental illnesses in the country, this study aimed to explore the associations of childhood, adulthood and late-life rural/urban place of residence with mental health outcomes, namely depressive symptoms and cognitive impairment, among older adults in India. The study also examined the relationship between older individuals' life-course rural/urban place of residence and late-life mental and cognitive health. METHODS Utilizing data from the Longitudinal Aging Study in India (n = 28,027 older adults age 60 years and above), the study employed multivariable logistic and linear regression models to examine the association between urban/rural residential status, life-course residence, depressive symptoms and cognitive impairment among older adults. RESULTS Childhood and adulthood place of residence was not associated with depressive symptoms in older men and women. Current rural place of residence was positively associated with depressive symptoms in older women [adjusted odds ratio (aOR): 1.37, confidence interval (CI): 1.05-1.80] but not men. Childhood [aOR: 1.88, CI: 1.16-3.04], adulthood [aOR: 2.00, CI: 1.26-3.16] and current rural residence [aOR: 1.93, CI: 1.27-2.91] was positively associated with cognitive impairment in men. Only current rural residence [aOR: 1.71, CI: 1.29-2.27] was associated with cognitive impairment in women. There was no significant association between life-course place of residence and depressive symptoms except in case of lifetime rural residence Respondents with urban-urban-urban (childhood-adulthood-current) place of residence were less likely to have depressive symptoms [adjusted coefficient (aCoef.): -0.14, CI: -0.21- -0.07] compared to those with rural-rural-rural place of residence. There were significant associations between life-course residence and cognitive impairment except among rural-urban-rural and urban-rural-rural migrants, showing an urban advantage in cognitive function among older adults. CONCLUSIONS This study showed significant associations between life-course residence and depressive symptoms among permanent rural/urban residents. The study also showed significant associations between life-course residence and cognitive impairment except among rural-urban-rural and urban-rural-rural migrants. Considering the rural disadvantage in mental and cognitive health among older adults, the government should continue to support policies that can improve access to education and healthcare among people residing in rural areas and women, in particular. The findings also urge social scientists and gerontologists in particular, to consider the importance of lifetime historical context while evaluating mental and cognitive health of older persons.

Association of social participation and psychological resilience with adverse cognitive outcomes among older Chinese adults: A national longitudinal study. J Affect Disord 2023; 327:54-63. [PMID: 36739004 DOI: 10.1016/j.jad.2023.01.112] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 01/22/2023] [Accepted: 01/30/2023] [Indexed: 02/05/2023]
Abstract
BACKGROUND Limited epidemiological evidence exists regarding the association of social participation and psychological resilience with cognitive health. This study aimed to comprehensively investigate the effects of social participation and psychological resilience on adverse cognitive outcomes among older adults in China. METHODS We used two waves (2011 and 2014) of data from the Chinese Longitudinal Survey of Health and Longevity (CLHLS), and 9765 respondents were eligible for the subsequent screening for the present prospective analysis. The Cox proportional hazards model was utilized to examine the association of social participation and psychological resilience with cognitive impairment, cognitive decline and greater cognitive decline. The restricted cubic spline plots were applied to clarify the dose-response relationships between them. RESULTS Compared to those with low social participation, participants with high social participation had a lower hazard ratio (HR) of 0.72 (95 % confidence interval [CI]: 0.59-0.89) for cognitive impairment, 0.85 (95 % CI: 0.76-0.94) for cognitive decline and 0.78 (95 % CI: 0.67-0.90) for greater cognitive decline. Participants with high psychological resilience had an HR of 0.77 (95 % CI: 0.63-0.95) for cognitive impairment 0.85 (95 % CI: 0.76-0.94) for cognitive decline and 0.85 (95 % CI: 0.73-0.98) for greater cognitive decline compared with those with low psychological resilience. Similar effects were observed for social participation score and psychological resilience score. The dose-response analysis also showed that the risk of adverse cognitive outcomes decreased gradually with increasing social participation scores and psychological resilience scores. Additionally, the multiplicative interaction between social participation and psychological resilience was not significant. LIMITATION All information was collected by self-report, which may lead to biases in the process of information collection. CONCLUSION In this study, social participation and psychological resilience were independently associated with a lower risk of adverse cognitive outcomes, and therefore both need to be considered as broader measures to preserve cognitive health among older Chinese adults.

Abstract
BACKGROUND Many studies have found that engaging in activities, including physical exercise, social interaction, and cognitive training, is beneficial for preventing cognitive decline among older adults; however, the demographic differences in the association between activity engagement and cognitive functions remain understudied. This study investigates: (a) the influence of activity engagement on cognitive functions among Chinese older adults, and (b) the moderating roles of age and gender in these associations . METHODS The data were derived from the China Health and Retirement Longitudinal Study in 2018, which included 9803 participants aged 60 or older. A multiple regression model was used to test the study hypotheses. RESULTS Engaging in physical activity (b = 1.578, p < .001), social interaction (b = 1.199, p < .001), and cognitive activity (b = 1.468, p < .001) was positively associated with cognitive functions, whereas the effect of volunteer activities on cognitive functions was not significant (b = -.167, p = .390). Light- and moderate-intensity activities were beneficial for cognition (light: b = .847, p < .001; moderate: b = 1.189, p < .001), but vigorous-intensity activity was negatively related to cognition (b = -.767, p < .001). In addition, women and participants with advanced age appeared to benefit more from cognitive activities than their male and younger counterparts, respectively (gender: b = 1.217, p = .002; age: b = .086, p = .004). The adverse effects of vigorous-intensity activities (including agricultural work) on cognitive health were stronger for women and younger participants (gender: b = -1.472, p < .001; age: b = .115, p < .001). The protective effects of moderate-intensity activities on people's cognition increased with increasing age (b = .055, p = .012). CONCLUSIONS The findings indicate that participating in physical, social, and cognitive activities can help older adults to maintain cognitive health. They suggest that older adults should select activities while considering activity intensity and their individual characteristics.

Abstract
Oral health is an important part of older adults' general health. The study examined the association between social participation (formal and informal) and remaining teeth and the urban-rural difference based on a national survey of older adults in China. The data of older adults were extracted from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and analyzed. A total of 11,948 respondents were ultimately involved, including 6836 urban respondents and 5112 rural respondents. Informal social participation and formal social participation were used to assess social participation. The number of remaining natural teeth was measured. Social participation was significantly associated with remaining teeth among older adults, after adjusting for confounders, a one-level increase in the informal social participation was associated with a decrease in natural teeth by 0.152 (95% CI = -0.274; -0.030) and a one-level increase in the formal social participation was associated with a decrease in natural teeth by 0.370 (95% CI = -0.585; -0.156). In addition, the association between social participation (formal and informal) and remaining teeth was observed among urban older adults, but not rural older adults. A high level of social participation may effectively decrease the risk of oral-health problems for the Chinese older adults. The findings suggest recommendations for an older adults-targeted policy and the practice of oral-health promotion. However, the urban-rural difference should be taken into full consideration in social-participation-driven oral-health promotion interventions.

Abstract
Background Although outdoor air pollution is reported to have a negative effect on frailty, evidence involving household air pollution is sparse. Methods A cohort study on older participants aged ≥65 years from the Chinese Longitudinal Healthy Longevity Survey was conducted between 2011/2012 and 2014. Household cooking fuel types were determined by self-reported questionaries, and were dichotomized into clean or biomass fuels. The frailty status was evaluated via a 46-item frailty index (FI) and the FRAIL scale, respectively. Frailty was identified if FI >0.21 or FRAIL score ≥3. Cox proportional hazards models were employed to examine the relationship between cooking fuels and incident frailty. And the effects of swapping cooking fuels on frailty risk were also explored. Results Among 4,643 participants (mean age at baseline 80.9 ± 9.6 years, 53.7% male) totaling 11,340 person-years, 923 (19.9%) incident frailty was identified using FI. Compared to clean fuels, cooking with biomass fuels was intricately linked to a 23% rise in frailty risk (hazard ratio [HR] 1.23, 95% confidence interval [CI] 1.06-1.43). A similar association was detected between biomass cooking fuels and frailty measured by the FRAIL scale (HR 1.24, 95% CI 1.04-1.50). Sensitive analyses supported the independent relationship between biomass fuels and frailty. Stratified analyses revealed that the frailty risk was higher among town residents (HR 1.44, 95% CI 1.13-1.84) and participants not exercising regularly (HR 1.35, 95% CI 1.11-1.64). In comparison with persistent biomass fuels usage, switching to clean fuels had a trend to reduce the frailty risk, and the opposite effect was observed when swapping from clean to biomass fuels. Conclusion Cooking with biomass fuels was associated with an increased frailty risk in older adults, especially amongst those living in town and those lacking regular exercise. More studies are needed to confirm our findings and to evaluate the potential benefits of reducing indoor biomass fuel usage.

Abstract
Proper cognitive functions are critical to the life of the elderly. With the rapid aging of the population, community support plays an important role in cognitive functioning. This study examines the association between community support and the level of cognitive functioning in the elderly, and the mediating effect of social participation in the relationship. Based on the panel data of China Longitudinal Healthy Longevity Survey (CLHLS) in 2005, 2008, 2011, 2014, and 2018, people aged 65 and over are selected as the research object (N = 35,479). The panel Logit model is used to analyze the influence of community support on their cognitive functioning. In addition, the stepwise regression and KHB decomposition methods are used to test the influence mechanism of community support on their cognitive function. The benchmark regression results show that there is a significant correlation between community support and cognitive function in the elderly (OR: 1.64, 95% CI: 1.41–1.91, p < 0.01). Daily care (OR: 1.75, 95% CI: 1.33–2.29, p < 0.01) has the strongest impact on the cognitive function of the elderly, followed by health care (OR: 1.70, 95% CI: 1.43–2.01, p < 0.01) and legal support (OR: 1.64, 95% CI: 1.37–1.95, p < 0.01), while psychological care (OR: 1.62, 95% CI: 1.31–2.01, p < 0.01) has the weakest impact on the cognitive function of the elderly. The results of the mediation effect test show that social participation plays a significant intermediary role in the impact of community support on the cognitive function of the elderly (mediation percentage: 16.89%), demonstrating that community support can improve the cognitive function of the elderly by promoting the social participation of the elderly. In classified community support, social participation plays a significant intermediary role in the impact of psychological care on cognition (mediation percentage: 46.10%).

Xiong J, Xue WX. The role of vitamin D in the link between physical frailty and cognitive function: A mediation analysis in community-dwelling Chinese older adults. Front Nutr 2022; 9:922673. [PMID: 35958260 PMCID: PMC9359101 DOI: 10.3389/fnut.2022.922673] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Accepted: 06/29/2022] [Indexed: 11/13/2022] Open
Abstract
Background Physical frailty and cognitive aging have important influences on poor clinical outcomes in older adults. Many studies have investigated the association between frailty and cognitive function, but whether vitamin D mediates the association between frailty and cognitive function is unclear. We explored the mediating role of vitamin D on the cross-sectional association between physical frailty and cognitive function using data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Methods We analyzed data from 1944 subjects aged 60 years and older from the 2011 CLHLS cohort. Frailty status was identified by the Osteoporotic Fracture Study (SOF) index. The Chinese version of the Mini-Mental State Examination (MMSE) was used to assess cognitive function. Linear regression models were used to examine the association between frailty, vitamin D, and cognition, adjusted for a range of covariates. Mediation analyses tested the indirect effects of vitamin D on physical frailty and cognitive function. Result Physical frailty was negatively associated with vitamin D levels and scores on the MMSE, and vitamin D levels were positively associated with scores on the MMSE. Linear regression analysis showed that physical frailty and serum vitamin D concentration were significant predictors of cognitive function. Importantly, mediation analysis showed that serum vitamin D concentration significantly mediated the relationship between physical frailty and cognitive function. Conclusion The association between physical frailty and cognitive function appears to be mediated by vitamin D. Future studies should explore whether serum vitamin D concentrations may mediate the association between physical frailty and cognitive decline and whether this mediating role is moderated by other factors.

Healthcare (Basel) 2022; 10:healthcare10071340. [PMID: 35885866 PMCID: PMC9323373 DOI: 10.3390/healthcare10071340] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/09/2022] [Accepted: 07/15/2022] [Indexed: 11/18/2022] Open
Abstract
Mild cognitive or neurocognitive impairment (MCI) may be more prevalent in rural areas. Differences between rural and urban MCI patients in terms of risk factors, course and prognosis are rarely reported. The present review aims to summarize the latest research on MCI in rural areas. A literature search was performed in the databases of PubMed, Scopus and ScienceDirect for articles published over the last decade. Eleven articles were included in this review, reporting on the differences between rural and urban MCI patients. Several risk factors, such as older age, lack of activities and food insecurity have been associated with MCI in both rural and urban areas, whereas others, such as obesity, adverse childhood experiences and plasma chemokine C-C motif ligand 11 (considered as a potential negative regulator of neurogenesis), differed according to the place of residence. No specific protective factor for rural women has been reported. There is some evidence that MCI may present earlier in rural residents, but that progression to dementia may be more rapid in urban residents. It seems that there may be clinically relevant differences in the onset, course and prognosis of MCI with regards to the place of residence (urban vs rural). Those differences should be taken into account for the design of health policies and service delivery across different settings.
