METHODS: Further to informed consent from 39 healthy subjects and 39 probable AD patients, 8.5 mL of peripheral blood was collected and serum was extracted. The differential levels of 12 serum cytokines extracted from peripheral blood samples were measured using Procarta Multiplex Cytokine and enzyme-linked immunoassay kits. Concentrations of cytokines were measured at 615 nm using a fluorometer.
RESULTS: Except for tumor necrosis factor-α, all classical pro-inflammatory cytokines (interleukin [IL]-1β, IL-6, IL-12 and interferon-γ) were found to be significantly upregulated (P 53.65 ρg/mL and <9.315 ρg/mL, respectively).
CONCLUSIONS: Both the non-classical pro-inflammatory CXCL-10 and anti-inflammatory IL-13 cytokines showed promising potential as blood-based cytokine biomarkers for AD. This is the first study of non-classical cytokine profiles of Malaysian AD patients. Geriatr Gerontol Int 2017; 17: 839-846.
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: A total of 2322 respondents aged ≥60 years were recruited at baseline using the multistage sampling method, followed up at 18 months and 36 months.
RESULTS: Response rates at baseline, 18 months and 36 months were 87.8%, 77.3% and 67.1%, respectively. At baseline, the prevalence of successful aging, usual aging and mild cognitive impairment was 11%, 73% and 16%, respectively. The prevalence of single and multimorbidity at baseline were 25.9% and 50.3%, respectively. The incidence rates of mild cognitive impairment at 18 months and 36 months were 6.5 and 5.6 per 100 person-years. The incidence rates of multimorbidity at 18 months and 36 months were 23.7 and 21.5 per 100 person-years, respectively.
CONCLUSIONS: The Long-Term Research Grant Scheme project: Towards Usual Aging study provides an opportunity to investigate the interactions between wide ranges of aspects of the older population in a nationally representative sample of the older population. Geriatr Gerontol Int 2019; 19: 233-239.
METHODS: A cross-sectional study was carried out in the central region of Malaysia from January to August 2015. The older adults enrolled in an ongoing prospective community-based geriatric cohort study and prescribed with medicines were interviewed using a 50-item validated questionnaire.
RESULTS: Of the 79 older adults interviewed, 39.2% had ≥4 prescribed medications. Most obtained their medications free-of-charge from government hospitals (66, 83.5%). Nearly half (35, 44.3%) had trouble reading labels for medicines that they had received. Chinese older adults (P = 0.001) and those with lower monthly household income (P
METHODS: Data from the National Health and Morbidity Survey 2018, a nation-wide, cross-sectional survey using a two-stage stratified sampling design, were analyzed. A representative sample of individuals aged ≥60 years identified through national sampling frames throughout Malaysia was included. Face-to-face interviews were conducted using validated questionnaires on activities of daily living (ADL) and instrumental ADL (IADL). Social support was measured using the Duke Social Support Index.
RESULTS: The overall prevalence of the presence of any limitations in ADL and IADL was 17.0% and 42.9% respectively. Overall prevalence of the older persons with low to fair social support was 30.8% and high to very high social support was 69.2%. Logistic regression analysis identified the following factors as being associated with limitations in ADL and IADL: being female, of older age, having a monthly income
METHODS: This study is part of the Long-term Research Grant Scheme - Towards Useful Ageing cohort study in Malaysia. Of a total of 174 participants with complete trace elements and oxidative and DNA damage data during baseline, only 147 (84.5%) were successfully followed up after 18 months. Participants who experienced any fall events in the previous 18 months during the follow-up were categorized as fallers.
RESULTS: Thirty participants (20.4%) reported at least one fall in the previous 18 months. The mean concentrations of aluminium, lead and zinc were significantly higher (P
METHODS: This is a cross-sectional study with two-stage stratified random sampling. In total, 3977 older persons participated in this study. Face-to-face interviews were conducted using a mobile device to obtain information about socio-demographic background, food insecurity, non-communicable diseases, social support and living arrangements. Descriptive and multiple complex sample logistic regression analyses were performed for data analysis.
RESULTS: The overall prevalence of food insecurity among older persons was 10.4%. Older persons from rural areas with no or only primary and secondary education, income less than RM 2000 (USD 477.57), at risk of malnutrition and not receiving very high social support were more likely to be food-insecure.
CONCLUSION: Approximately, one-tenth of Malaysian older adults were classified as food-insecure; particularly those living in rural areas from lower socio-economic status, not receiving very high social support and malnourished were more likely to be at risk. A specific nutrition program, such as meals on wheels and food vouchers, should be targeted toward older persons who are at risk to improve their malnutrition status. Geriatr Gerontol Int 2020; 20: 73-78.
METHODS: Cross-sectional data from the initial wave of the Malaysian Elders Longitudinal Research study were used. Basic demographics were obtained from the Global Questionnaire. Basic and instrumental activities of daily living were measured using the Katz and Lawton-Brody scales, and home hazards were identified using the Home Falls and Accidents Screening Tool. Participants were also asked if they had fallen in the previous 12 months.
RESULTS: Data were analyzed from 1489 participants. Hazards were frequently identified (>30%) in the toilet and bathroom areas (no grab rail, no non-slip mat, distant toilet), slippery floors, no bedside light access and inappropriate footwear. Lower educational attainment, traditional housing, Chinese ethnicity, greater number of home occupants, lower monthly expenditure, poor vision and younger age were the factors independently associated with home hazards.
CONCLUSIONS: This study provides evidence that home hazards are a product of the interaction of the individual's function within their home environment. Hazards are also influenced by local sociocultural and environmental factors. The relationship between home hazards and falls appears complex and deserves further evaluation.

METHODS: As treatment of Aβ42 has been shown to cause neuronal cell death, EC was first screened with Aβ42-incubated PC12 neuronal cells. Next, the compound was tested on the Drosophila melanogaster AD model using the rough eye phenotype assay, lifespan assay and negative geotaxis assay.
RESULTS: EC ameliorated PC12 cells from cell death linked to Aβ42 exposure. Using Drosophila expressing human Aβ42, feeding of EC was able to partially rescue the rough eye phenotype, lengthen the lifespan of AD Drosophila and enhanced the mobility of middle-aged AD Drosophila.
CONCLUSION: Overall, the results of this study showed that EC might possess therapeutic properties for AD. Geriatr Gerontol Int 2021; 21: 1125-1130.
METHODS: A nationwide population-based survey involving 3977 community-dwelling older persons aged ≥60 years was conducted via face-to-face interview, of whom 3466 older persons were eligible for screening using a locally validated tool. Elder abuse was defined as any one occurrence of neglect, financial, psychological, physical or sexual abuse perpetrated by someone in a position of trust that was experienced in the past 12 months.
RESULTS: About 9.0% of older persons in Malaysia have experienced elder abuse in the past 12 months, with neglect being the commonest type experienced (7.5%; 95% confidence interval [CI]: 5.54, 10.07). There is no significant difference by age group and geographical location. Males (adjusted odds ratio [aOR] 1.7; 95% CI: 1.06, 2.60), poorer social support (aOR 5.0; 95% CI: 2.25, 11.22), dependency in activities of daily living (aOR 2.1; 95% CI: 1.23, 3.44) and a previous history of abuse (aOR 10.1; 95% CI: 4.50, 22.86) show higher odds of experiencing elder abuse. Almost 5% of abused older persons reported experiencing multiple types of abuse. Reporting is low at 19.3% with none reporting to healthcare personnel.
CONCLUSIONS: The prevalence of elder abuse in this study is lower than global estimates, but similar to local studies. Preventive measures and programs are crucial to overcoming elder abuse and need to be carried out at multiple levels - the individual, community, healthcare and other stakeholders. Geriatr Gerontol Int 2020; 20: 85-91.
METHODS: A double-blind quasi-experiment was carried out on NC (n = 43) and NCI (n = 33) groups. Participants in each group were randomly assigned into treatment and control programs groups. The treatment group underwent auditory-cognitive training, whereas the control group was assigned to watch documentary videos, three times per week, for 8 consecutive weeks. Study outcomes that included Montreal Cognitive Assessment, Malay Hearing in Noise Test, Dichotic Digit Test, Gaps in Noise Test and Pitch Pattern Sequence Test were measured at 4-week intervals at baseline, and weeks 4, 8 and 12.
RESULTS: Mixed design anova showed significant training effects in total Montreal Cognitive Assessment and Dichotic Digit Test in both groups, NC (P
METHODS: Matching variables from the Towards Useful Aging and Malaysian Elders Longitudinal Research datasets related to falls, physical performance and determinants of falls were identified and pooled for analysis. The Timed Up and Go test and dominant handgrip strength tests were used as physical performance measures. Falls were self-reported, and functional status was assessed using activities of daily living.
RESULTS: Data of 3935 participants, mean age 68.9 ± 6.8 years, 2127 (54.0%) women and 1807 (46.0%) men were extracted for analyses. In an adjusted model, independent risk factors for falls from this cohort studies were diabetes (OR 1.258), arthritis (OR 1.366), urinary incontinence (OR 1.346), poor self-rated health (OR 1.293), higher body mass index (OR 1.029) and lower handgrip strength (OR 1.234).
CONCLUSIONS: Although the risk factors that emerged from our analyses were similar to available studies among older adults, the Timed Up and Go test did not appear as one of the risk factors in the present study that included middle-aged adults. Our findings will require confirmation in a prospective study. Geriatr Gerontol Int 2019; 19: 798-803.
METHODS: Data for this study came from the four waves of the China Health and Retirement Longitudinal Survey. A latent growth model was used to analyze the functional disability of 5044 older adults aged 60 and over in 2011 who survived to 2018.
RESULTS: Pathologies are closely associated with functional disability trajectories, and higher numbers of comorbidities relate to more disabilities. Risk factors and intra- and extra-individual factors affect functional disability trajectories and work through independent and shared mechanisms. The effects of risk factors can be traced to childhood conditions, and higher childhood and adulthood socioeconomic status is related to fewer functional disabilities.
CONCLUSION: Functional disability trajectories are dynamic processes related to pathologies, intra-, and extra-individual factors, and life-course risk factors, and thus prevention and control measures should focus on both childhood and adulthood. Promoting working in later life and improving childhood socioeconomic status deserve prompt attention. Geriatr Gerontol Int 2023; 23: 817-829.
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. Geriatr Gerontol Int 2017; 17: 1914-1920.
METHODS: A cross-sectional survey among community dwelling older persons utilizing stratified cluster sampling was conducted in 2018. Well-trained interviewers conducted a face-to-face interview with older persons aged ≥60 years to collect information on participants' sociodemographic characteristics, self-perception on general as well as oral health using the Geriatric Oral Health Assessment Index (GOHAI). Multivariate analysis of the data collected was performed using SPSS version 23.
RESULTS: Overall, the GOHAI mean ± SD score for older persons in Malaysia was 51.83 ± 7.98, which was an average of fair mean (P
METHODS: Data from a nation-wide community-based cross-sectional study were analyzed. This study was conducted using a two-stage stratified random sampling design. In total, 3772 older adults aged ≥60 years responded to the survey. Depression was identified using a validated Malay version of the Geriatric Depression Scale (M-GDS-14), with those scored ≥6 categorized as having depression. Functional limitations were assessed using both Barthel's Activities of Daily Living (ADL) and Lawton's Instrumental Activities of Daily Living (IADL). The relationship was determined by multivariate logistic regression, adjusted for other variables.
RESULTS: The prevalence of depression was 11.5% (95% confidence interval [CI] 9.4, 13.4). Multiple logistic regression analysis found that older adults with limitations in ADL were 2.6 times more likely of having depression (adjusted odds ratio [aOR] 2.58, 95% CI 2.01, 3.32), while those with limitations in IADL the risk of having depression was almost doubled (aOR 1.68, 95% CI: 1.32, 2.14). Other significant factors were incontinence (aOR 3.33, 95% CI: 2.33, 4.74), chronic medical illness (aOR 1.44, 95% CI: 1.15, 1.81), current smoker (aOR 4.19, 95% CI: 1.69, 10.39), poor social support (aOR 4.30, 95% CI: 2.98, 6.20), do not have partner, ethnic minorities and low individual monthly income.
CONCLUSIONS: Older adults with functional limitation in both basic ADL and complex IADL are independently at higher risk of having depression. Geriatr Gerontol Int 2020; 20: 21-25.
