METHODS: The study included 2322 nationally represented community-dwelling older persons in Malaysia who participated in the baseline study of Neuroprotective Model for Healthy Longevity. In order to test the moderating effect of emotional support on the association between disability and life satisfaction, a series of hierarchical multiple linear regression models were utilized, after controlling for potential covariates associated with life satisfaction.
RESULTS: Bivariate analyses showed that disability negatively predicted life satisfaction, whereas emotional support positively predicted life satisfaction. Furthermore, the moderated hierarchical regression analysis showed that emotional support moderated the association between disability and life satisfaction, after controlling for potential covariates, such that the negative relationship between disability and life satisfaction was stronger for individuals with lower levels of emotional support.
CONCLUSIONS: The presence of emotional support might reduce the negative effects of disability on life satisfaction. These findings have important clinical implications, especially in developing better strategies to help disabled older persons to cope with their disabilities; with the hope that in the long term, a society with healthy longevity can be established.

METHODS: The study involved 1790 community-dwelling older adults aged 60 and above living with at least one chronic medical condition. The Satisfaction with Life Scale and Revised Intrinsic/Extrinsic Religious Orientation Scale were used to measure life satisfaction and religious orientation. Moderated hierarchical multiple regression was used to test the moderation effect.
RESULTS: Results showed that while intrinsic religiosity was positively associated with life satisfaction, extrinsic religiosity was found to have a negative relationship with life satisfaction. Gender moderated the association between intrinsic religiosity and life satisfaction.
CONCLUSIONS: The findings suggested that the positive impact of intrinsic religiosity on life satisfaction was stronger in older women living with morbidity and multimorbidity. Healthcare practitioners can help disadvantaged older women in identifying their religious values and practices to improve their subjective wellbeing.
METHODS: This study involved 2004 nationally representative community-dwelling older Malaysians from the bottom 40% household income group. Financial well-being was assessed by the four-item financial satisfaction scale, while life satisfaction was measured by the Satisfaction with Life Scale. Cognitive function was measured by using the Malay version of the Mini-Mental State Examination. Hierarchical multiple regression was used as the prime method for statistical analysis.
RESULTS: Financial well-being was positively associated with life satisfaction and cognitive function. Sex moderated the relationship between financial well-being and life satisfaction but not between financial well-being and cognitive function.
CONCLUSIONS: Financial well-being and life satisfaction were strongly correlated among older women, although no gender difference was found for the relationship between financial well-being and cognitive function. It appears financial well-being strongly predicts mental health. As such, poverty eradication initiatives targeting low-income older adults should be implemented to sustain life satisfaction and cognitive function.
METHOD: The study included 2322 nationally representative community-dwelling elderly in Malaysia, randomly selected through a multi-stage proportional cluster random sampling from Peninsular Malaysia. The elderly were surveyed on socio-demographic information, cognitive function, depression and intrinsic religiosity. A four-step moderated hierarchical regression analysis was employed to test the moderating effect. Statistical analyses were performed using SPSS (version 15.0).
RESULTS: Bivariate analyses showed that both depression and intrinsic religiosity had significant relationships with cognitive function. In addition, four-step moderated hierarchical regression analysis revealed that the intrinsic religiosity moderated the association between depression and cognitive function, after controlling for selected socio-demographic characteristics.
CONCLUSION: Intrinsic religiosity might reduce the negative effect of depression on cognitive function. Professionals who are working with depressed older adults should seek ways to improve their intrinsic religiosity as one of the strategies to prevent cognitive impairment.
METHODS: This study involved 2322 representative community residents aged 60-92 years in Peninsular Malaysia. Cognition was measured by Mini-Mental State Examination (MMSE), loneliness was assessed by three-item loneliness scale, and neuroticism was assessed by the Short-Form Revised Eysenck Personality Questionnaire. Hierarchical multiple linear regression and Sobel tests were used for mediation analyses.
RESULTS: Both loneliness (β = -0.04, P = 0.03) and neuroticism (β = -0.07, P < 0.001) were negatively and significantly associated with cognitive function, and most importantly, neuroticism mediated the association between loneliness and cognition (from β = -0.04, P = 0.03 to β = -0.03, P = 0.10).
CONCLUSION: Neuroticism may be the potential mechanism underlying the relationship between loneliness and cognitive function in older persons.
METHODS: Data were obtained from the first wave of a Peninsular Malaysia national survey - "Identifying Psychosocial and Identifying Economic Risk Factor of Cognitive Impairment among Elderly". Log-binomial regression was used to identify intersectional effects and associations between control variables and health outcomes. A comparison between Malay and non-Malay older adults within the same poverty group, as well as hardcore poor and non-hardcore poor older people within the same ethnicity groups, were conducted to understand the intersectional effects of ethnicity/race and poverty on health.
RESULTS: Prevalence of cognitive impairment was highest among hardcore poor Malay group, while the risk of depression and multimorbidity were highest among hardcore poor non-Malays. In the hardcore poor group, Malay ethnicity was associated with higher prevalence of cognitive impairment but lower prevalence of depression risk and multimorbidity. In the Malay group, hardcore poor was associated with higher prevalence of cognitive impairment; however, no association was found between hardcore poor with depression risk and multimorbidity after controlling for covariates.
CONCLUSIONS: Health outcomes of Malaysian older adults differ according to ethnicity and socioeconomic status. Given the importance of demographic characteristics on health outcomes, design of interventions targeting older adults within multi-ethnic settings must address specific characteristics, especially that of ethnicity and sociodemographic status so as to fulfil their needs. Several implications for future practice were discussed.
METHODS: Data of 2322 representative community-dwelling older adults were obtained from the first wave of the "Longitudinal Study on Neuroprotective Model for Healthy Longevity" national survey. Cognitive function, physical fitness and social network was assessed through Malay-version of Mini-Mental State Examination, 2-min step test and Lubben Social Network Scale-6 respectively. Moderated hierarchical multiple regression was employed to investigate if social networks moderate the relationship between physical fitness and cognitive function.
RESULTS: A positive association between physical fitness and cognitive function were found upon controlling for covariates. Moderated hierarchical multiple regression revealed social networks to be a moderator of the association between physical fitness and cognitive function. When physical fitness was low, those with small social network revealed lowest cognitive function.
CONCLUSIONS: Social networks moderated the relationship between physical fitness and cognitive function as older adults with low levels of physical fitness and small social networks revealed lowest cognitive function. Therefore, community support or peer-based interventions among physically unfit older adults should be implemented to promote cognitive function.
METHODS: The study included 2322 community-dwelling older adults in Malaysia who were randomly selected through a multistage proportional cluster random sampling technique. Global cognition construct was measured by the Mini-Mental State Examination and Montreal Cognitive Assessment; psychosocial stress construct was measured by perceived stress, depression, loneliness, and neuroticism; and processing speed was assessed by the Digit Symbol Substitution Test. Structural equation modelling was used to analyze the mediation and moderation tests.
RESULTS: Processing speed was found to partially mediate the relationship between psychosocial stress and global cognition (β in the direct model = -0.15, P
METHOD: The study included 2322 community-dwelling elderly in Malaysia, randomly selected through a multi-stage proportional cluster random sampling from Peninsular Malaysia. The elderly were surveyed on socio-demographic information, biomarkers, psychosocial status, disability, and cognitive function. A biopsychosocial model of cognitive function was developed to test variables' predictive power on cognitive function. Statistical analyses were performed using SPSS (version 15.0) in conjunction with Analysis of Moment Structures Graphics (AMOS 7.0).
RESULTS: The estimated theoretical model fitted the data well. Psychosocial stress and metabolic syndrome (MetS) negatively predicted cognitive function and psychosocial stress appeared as a main predictor. Socio-demographic characteristics, except gender, also had significant effects on cognitive function. However, disability failed to predict cognitive function.
CONCLUSION: Several factors together may predict cognitive function in the Malaysian elderly population, and the variance accounted for it is large enough to be considered substantial. Key factor associated with the elderly's cognitive function seems to be psychosocial well-being. Thus, psychosocial well-being should be included in the elderly assessment, apart from medical conditions, both in clinical and community setting.
METHODS: Secondary analysis was carried out of data from the Malaysian national survey that involved 2322 community residents aged 60 years or older in Peninsular Malaysia. Cognition was measured by the digit symbol substitution test. Metabolic syndrome was assessed by five biomarkers: triglyceride, fasting blood sugar, systolic blood pressure, cholesterol ratio and body mass index. Chronic conditions were assessed by self-reported medical history. The structural equation modeling technique was used to analyze the mediation and moderation tests.
RESULTS: The number of chronic conditions partially mediated the association between metabolic syndrome and cognition. Men and women did not differ in the relationship between metabolic syndrome and cognition; however, the number of chronic conditions was found to be negatively associated with cognition in older women, but not in men.
CONCLUSIONS: Metabolic syndrome might increase the likelihood of older adults to suffer from more chronic conditions; these responses might reduce their cognition. To prevent cognitive decline in old age, specific intervention to minimize the number of chronic conditions by reducing their vascular risk factors is warranted, especially among older women.
