“…The obvious difference reported in Zheng et al [16] study as compared to Reyez-Ortiz et al [36] and our study could be due to the study design. The findings of this study were also in contrast to those reported by Effendi-Tenang et al [33] , where they found an association between distance VI and poor MoCA score.…”

AIM: To determine the association between distance and near visual acuity (VA) and cognitive function among older adults in Selangor, Malaysia. METHODS: A total of 230 older adults (age ≥60y) participated in this study. Habitual distance and near VA were measured using the Early Treatment Diabetic Retinopathy Study Chart and Lighthouse Near Visual Acuity Chart, respectively. Global cognitive function was assessed using the Mini-Mental State Examination (M-MSE) and the Malay language version of the Montreal Cognitive Assessment (M-MoCA). Digit Symbol (DS) subtest was used to measure information processing. RESULTS: No significant association was observed between vision and M-MSE and M-MoCA scores. However, poor distance and near VA were found to be significantly associated with low DS scores [distance VA: β=-0.01, R2=0.1, P=0.02; odds ratio (OR)=2.84, 95% confidence interval (CI), 1.10-7.33, P=0.03; near VA: β=-0.05, R2=0.08, P=0.00; OR=3.32, 95%CI, 1.28-8.59, P=0.01]. CONCLUSION: Poor vision is associated with a decline in information processing in older adults and substantiates the importance of preserving good vision in maintaining cognitive function.

“…MoCA was translated into the Malay language and the reported α-coefficient was 0.69 [26] . A similar principle of eliminating items requiring vision was used for MoCA, leaving a total score of 22 with a cut-off score of 18 indicating the possible presence of cognitive impairment [32][33] .…”

“…Non-communicable diseases (NCD) such as hypertension, diabetes, and atherosclerosis, have been identified as potential modifiable risk factors for dementia [33]. Despite the fact that diabetes was found to be more prevalent in individuals with cognitive impairment within the same cohort measured by the MoCA-Blind version, it had no effect on the relationship between visual impairment and cognitive function [34]. This study also found that diabetes was not a risk factor for lower cognitive performance within MELoR population, this time using the full version of the MoCA test.…”

Introduction: Despite cognitive impairment being a major health issue within the older population, limited information is available on factors associated with cognitive function among Asian ethnic groups. The objective of this study was to identify ethnic-specific sociodemographic risk factors which are associated with cognitive performance. Methods: Cross-sectional analysis of the Malaysian Elders Longitudinal Research (MELoR) study involving community-dwelling individuals aged >55 years was conducted. Information on sociodemographic factors, medical history, and lifestyle were obtained by computer-assisted interviews in participants’ homes. Cognitive performance was assessed with the Montreal Cognitive Assessment (MoCA) tool during subsequent hospital-based health checks. Hierarchical multiple linear regression analyses were conducted with continuous MoCA scores as the dependent variable. Results: Data were available for 1,140 participants, mean (standard deviation [SD]) = 68.48 (7.23) years, comprising 377 (33.1%) ethnic Malays, 414 (36.3%) Chinese, and 349 (30.6%) Indians. Mean (SD) MoCA scores were 20.44 (4.92), 23.97 (4.03), and 22.04 (4.83) for Malays, Chinese, and Indians, respectively (p = 0.01). Age >75 years, <12 years of education, and low functional ability were common risk factors for low cognitive performance across all three ethnic groups. Cognitive performance was positively associated with social engagement among the ethnic Chinese (β [95% CI] = 0.06 [0.01, 0.11]) and Indians (β [95% CI] = 0.16 [0.09, 0.23]) and with lower depression scores (β [(95% CI] = −0.08 [−0.15, −0.01]) among the ethnic Indians. Conclusion: Common factors associated with cognitive performance include age, education, and functional ability, and ethnic-specific factors were social engagement and depression. Interethnic comparisons of risk factors may form the basis for identification of ethnic-specific modifiable risk factors for cognitive decline and provision of culturally acceptable prevention measures.

“…Participants were drawn from the Malaysian Elders Longitudinal Research (MELoR) study, which involved community-dwelling individuals aged 55 to 97 were recruited based on the official retirement age in Malaysia in 2013 and taking into account the life expectancy of Malaysians (Effendi-Tenang et al 2020). Eligible participants for the MELoR study were selected through simple randomization from the electoral rolls of three parliamentary constituencies in the Klang Valley of Malaysia, stratified by age deciles and the three ethnic groups of Malays, Chinese and Indians.…”
