Abstract

Abstract: The Montreal Cognitive Assessment (MoCA) is primarily used for mild cognitive impairment (MCI) screening in older adults in the clinical setting. The epidemiology of MoCA performance in population-based settings remains to be better characterized. The goal of this study was to assess short-term changes in MoCA scores, and examine selected risk factors, with emphasis on the evaluation of the a priori hypotheses of engagement in volunteer activities as a protective factor against cognitive deterioration. Data of the prospective study were from 438 community-dwelling older Japanese (age range: 65–84) living in an urban area in Tokyo (2013–2015). Outcome was short-term cognitive deterioration, defined as decline of 2 or more points in MoCA-J scores obtained 2 years apart. Multivariate logistic regression was used with adjustment for age, gender, chronic conditions, self-rated health, baseline MoCA-J, and recent hospitalization. Analytic sample had mean age of 73.3 ± 5.4 years old; and mean MoCA-J of 24.4 ± 3.8; 58.2% were female. Of study participants, 38.1% experienced cognitive deterioration. Engagement in volunteer activities was associated with lower adjusted odds of subsequent MoCA-J deterioration 2 years later (odds ratio [OR]: 0.32; 95% confidence interval [CI]: 0.100–0.98); contrastingly, going out of the home less than once/day (OR: 2.90; 95% CI: 1.24–6.80), and slower timed Up and Go (OR: 1.28; 95% CI: 1.00–1.60 per 1 second slower) were risk factors for cognitive deterioration In conclusion, engagement in volunteer activity was an independent protective factor against cognitive deterioration, while homebound status and worse mobility were risk factors of short-term MoCA-J deterioration.
