“…responses were categorized as yes or no). Cognitive decline (typical values on the Transcultural Cognitive Test [ 23 ], which was based on the following eight domains: orientation, attention, verbal learning, evoking memory, spatial ability, visual memory, executive function, and numeracy were used; answers were classified as: no deterioration, light deterioration, severe deterioration, or inconclusive test. Depression (measured using a modified version of the United States Center for Epidemiological Studies—Depression Scale (CES-D), which has been validated for the MHAS population [ 24 ].…”

Factors associated with occasional and recurrent falls in Mexican community-dwelling older people

Falls are a frequent event among older adults that can cause wounds, disability, psychological disorders, and premature death. Although the large number of existing studies on the issue, few have been conducted in middle- and low-income countries. The objective of the present study is to identify the sociodemographic, medical, and functional performance factors associated with occasional and recurrent falls in Mexican older adults dwelling in community. Cross-sectional analysis of 9 598 adults ≥60 years old who participated in the fourth round (2015) of the Mexican Health and Aging Study. Bivariate tests were performed to evaluate the differences between covariates by distinct fall groups (no falls, occasional falls, and recurrent falls). Multiple logistic regressions with unadjusted and adjusted models were estimated. Approximately 46% of older adults had had at least one fall during the previous two years (one fall 16% and recurrent falls 30%). Occasional falls were only associated with being a woman; in addition to the sex, recurrent falls were strongly associated with advanced age, rural residence, bad and very bad self-perception of health status, activity-limiting pain, urinary incontinence, depression, arthritis, limitations in basic activities of daily living, and limitations in advanced activities of daily living. Falls, primarily recurrent falls, deserve to be addressed through multifactorial strategies that include different areas of intervention.

“…These differences are associated with genetic 4 , environmental and social determinants 5 - 8 , and individual characteristics of the elderly 9 , 10 . Previous population-based studies with national samples from several countries have shown that socio-demographic factors 11 , 12 and differences between rural and urban residence areas 13 , 14 are related to alterations in cognitive function among older adults, showing important cultural and geographic variations 11 , 12 , 15 , 16 .…”

OBJECTIVE To investigate macroregional variations in cognitive function in a national sample representative of the Brazilian population aged 50 years and older.METHODS Data from the baseline of the Longitudinal Study of Brazilian Elderly (ELSI-Brazil), collected between 2015 and 2016, were used. Memory was measured by means of a 10-word list and executive function, by semantic verbal fluency, based on the naming of animals. Gender, age, education, and rural or urban residence were potentially confoundingRESULTS Among the 9,412 ELSI-Brazil participants, 9,085 were included in the analysis; 53.9% were women and the average age was 63.0 (0.42) years. After adjusting for potential confounding variables, average scores for memory and verbal fluency were lower in the Northeast region and higher in the Midwest and Southeast, respectively. In the South region, higher scores were found for immediate and combined memory. In all regions, older participants and those with lower schooling had worse scores for memory and verbal fluency.CONCLUSIONS There are differences in cognitive function among older adults in the different macroregions, independent of age, gender, schooling, and rural or urban residence.

“…A detailed description of the administration and scoring of the CCCE in the MHAS has been provided by Mejia-Arango et al [30]. The CCCE includes measures for verbal learning (immediate recall of verbal list of eight words, score 0–8 points), verbal memory (repeat list of eight words from verbal learning trial, score 0–8 points), visuospatial abilities (copying of two figures, score 0–6 points), visual memory (recall of two figures from visuospatial abilities trial, score 0–6 points), and attention (one minute to identify target stimulus (60) among a visual array of other stimuli, score 0–60 points).…”

Background Several dementia risk indices have been developed for older adults in high-income countries. However, no index has been developed for populations in low- or middle-income countries. Objective To create a risk index for predicting severe cognitive impairment among adults aged ≥60 in Mexico and to compare the accuracy of this index to the Dementia Screening Indicator (DSI). Methods This study included 3,002 participants from the Mexican Health and Aging Study (MHAS) interviewed in 2001 and 2012. The MHAS risk index included sociodemographic, health, and functional characteristics collected in 2001. A point value based on the beta coefficients from a multivariable logistic regression model was assigned to each risk factor and the total score was calculated. Results The MHAS risk index (AUC = 0.74 95% CI = 0.70–0.77) and DSI (AUC = 0.72 95% CI = 0.69–0.77) had similar accuracy for discriminating between participants who developed severe cognitive impairment from those who did not. A score of ≥16 on the MHAS risk index had a sensitivity of 0.69 (95% CI = 0.64–0.70) and specificity of 0.67 (95% CI = 0.66–0.69). A score of ≥23 on the DSI had a sensitivity of 0.56 (95% CI = 0.50–0.63) and specificity of 0.78 (95% CI = 0.76–0.79). Discussion The MHAS risk index and DSI have moderate accuracy for predicting severe cognitive impairment among older adults in Mexico. This provides evidence that existing dementia risk indices may be applicable in low- and middle-income countries such as Mexico. Future research should seek to identify additional risk factors that can improve the accuracy of the MHAS risk index.
