“…Higher prevalence of dementia was found among the younger elderly, aged 65-69 years, in Latin American countries compared with developed nations, whereas the older elderly presented a higher rate of dementia in developed countries (3) . These findings corroborate those of studies associating differences in functional or cognitive performance with social, ethnic, economic, cultural or demographic diversity (4,5,6,7) , as well as with genetic factors (8) . Cognitive-behavioral and functional-structural changes may occur as a result of education, a multidimensional variable that encompasses quality of life, socioeconomic level, and activities of daily living (9) .…”

Purpose: 1) Compare the discourse performance between young and older adults from the Brazilian Federal District (DF); 2) Compare the mean discourse performance of participants from the DF with the normative discourse of a population from a different region of the country; 3) Verify whether the variables age, educational level and socioeconomic status and scores on the cognitive, behavioral and functional screening tests were associated with discourse performance. Method: A total of 60 healthy volunteers from the DF, 30 older adults and 30 young adults, were selected. Participants were divided into two subgroups according to educational level: low education and high education. The four narrative discourse subtests of the Montreal Communication Evaluation Battery, Brazilian Portuguese version (MAC-BR) were applied to the study sample. Results: Discourse scores of the older adults were statistically higher than those of the young adults. The discourse scores in the high education group were also better than those in the low education group, with statistically significant difference observed in only one of the MAC-BR subtests. Discourse performance was associated with the sociodemographic variable and the scores on the cognitive and functional screening tests. The discourse performance of the DF sample differed from the national normative discourse with statistically significant difference. Conclusion: The discourse performance of older adults from the Brazilian Federal District differed from that of young adults from the same region, as well as from that of older adults from southern Brazil. Discourse performance was associated with several different variables.

“…Physical functioning, such as ADLs, is a good measurement of functional capacity and a proxy of health status widely used in healthy aging studies (Kojima, 2018;Zeng et al, 2017;Zhang et al, 2019). Previous studies reported that ADL limitations indicated an increased risk of being in the declining group (Hartley et al, 2017;Lindbergh et al, 2016).…”

ABSTRACTBackground:Cognitive decline in advanced age is closely related to dementia. The trajectory of cognitive function in older Chinese is yet to be fully investigated. We aimed to investigate the trajectories of cognitive function in a nationally representative sample of older people living in China and to explore the potential determinants of these trajectories.Methods:This study included 2,038 cognitively healthy persons aged 65–104 years at their first observation in the Chinese Longitudinal Healthy Longevity Survey from 2002 to 2014. Cognitive function was measured using the Chinese version of the Mini-Mental State Examination (MMSE). Group-based trajectory modeling was used to identify potential heterogeneity of longitudinal changes over the 12 years and to investigate associations between baseline predictors of group membership and these trajectories.Results:Three trajectories were identified according to the following types of changes in MMSE scores: slow decline (14.0%), rapid decline (4.5%), and stable function (81.5%). Older age, female gender, having no schooling, a low frequency of leisure activity, and a low baseline MMSE score were associated with the slow decline trajectory. Older age, body mass index (BMI) less than 18.5 kg/m2, and having more than one cardiovascular disease (CVD) were associated with the rapid decline trajectory.Conclusion:Three trajectories of cognitive function were identified in the older Chinese population. The identified determinants of these trajectories could be targeted for developing prevention and intervention strategies for dementia.

“…8 Each item of the mMMSE was scored as "1" if the answers of participants were correct and "0" if wrong. 8 More correct answers demonstrated better cognitive function. Previous studies 19 have indicated that the reliability of the mMMSE was high (Cronbach's α = 0.98).…”

Centenarians, defined as the population aged 100 years or over, have been a symbol of longevity in most countries historically. 1 According to the Brocklehurst's textbook, 2 it is estimated there will be 850 000 centenarians living in the United States in 2050. Similarly, as an ageing society, there were 47 000 centenarians in China in 2012, 3 and the number of older adults (OAs) aged 60 or above is expected to reach 483 million, 4 representing 1/4 of the older people worldwide. 5 Along with rapid ageing, the population of Chinese OAs suffering from dementia has been projected to rise from 9 million in 2010 to 18 million by 2030. 6

Effect of sociodemographic and physical activity on cognitive function in older adults: A nationwide cross‐sectional survey

Abstract: OAs' sex, age, co-residence, years of schooling, and IADL were significantly associated with cognitive function. Improving OAs' IADL, especially in lower social classes, may help to improve the overall cognitive function of the OAs.
