RESUMO
Abstract Introduction Loneliness and social isolation are known risk factors for cognitive decline; their effect in older adults (OA) after COVID-19 lockdown is emerging. Objective To establish an association between loneliness and social isolation, with daily cognitive function in Mexican OA during the first wave of the COVID-19 pandemic. Method Cross-sectional study, derived from the cohort "The impact of COVID 19 on well-being, cognition, and discrimination among older adults in the United States and Latin America", which included 308 OA recruited between March-August 2020 whose daily cognitive function were determined with the Everyday Cognition Scale (E-Cog) as dichotomized score (cut point: 1.31 for normal cognition). Loneliness and social isolation were binomial variables. Results The mean age was 65.4 ± 7.9 years, 75.7% were women. The mean continuous E-Cog score was 57.4 (SD = ± 19.1), 49.1% had a score < 1.31 (normal cognition), while 50.9% had a higher score (cognitive impairment). Eighty four percent of participants reported loneliness, 79.9% reported social isolation. Multivariate regression model showed a negative and statistically significant association between social isolation and loneliness and E-Cog, adjusted by age, sex and education level (β = -.046, 95% CI = [-.8, -.013], p = .007; β = -.16, 95% CI = [-.08, -.018], p = .003), and a positive association with subjective memory complaint (β = .81, 95% CI = [-.16, -.11], p = < .001). Discussion and conclusion These data suggest the need for increased vigilance of those who have loneliness and social isolation due to its potential deleterious effect on cognitive function.
Resumen Introducción La soledad y el aislamiento social son factores de riesgo conocidos para el deterioro cognitivo; su efecto en las personas mayores (PM) después del confinamiento por COVID-19 está emergiendo. Objetivo Establecer una asociación entre la soledad y el aislamiento social, con la función cognitiva diaria en PM mexicanas durante la primera ola de la pandemia por COVID-19. Método Estudio transversal derivado de la cohorte "The impact of COVID 19 on well-being, cognition, and discrimination among older adults in the United States and Latin America", incluyó 308 AM reclutados de marzo-agosto 2020, la función cognitiva diaria fue evaluada con Everyday Cognition Scale (E-Cog) con un punto de corte 1.31 (cognición normal); la soledad y el aislamiento social fueron variables binomiales. Resultados La media de edad fue 65.4 ± 7.9 años, 75.7% mujeres. E-Cog promedio fue 57.4 (DE = ± 19.1), 49.1 % tenía una puntuación < 1.31 (cognición normal), 50.9% > 1.31 (deterioro cognitivo). Ochenta y cuatro por ciento de los participantes reportaron soledad, 79.9% aislamiento social. El modelo de regresión multivariado mostró una asociación negativa y estadísticamente significativa entre aislamiento social y soledad con E-Cog (β = -.046, IC 95% = [-.8, -.013], p = .007; β = -.16, IC 95% = [-.08, -.018], p = .003), y una asociación positiva con queja de memoria subjetiva (β = .81, IC 95% = [-.16, -.11], p = < .001) ajustado a edad, sexo y escolaridad. Discusión y conclusión Estos datos sugieren la necesidad de una mayor vigilancia de quienes presentan soledad y aislamiento social debido a su potencial efecto deletéreo sobre la función cognitiva.
RESUMO
Demographic aging has led to an increase in the prevalence of different diseases, including the so-called geriatric syndromes (GS), like depression, disability and frailty phenotype (FP). Spirituality and religious practices (RP) have been associated with positive health outcomes and could be a protective factor against the development of some GS. Study aims was to determine the frequency of spirituality and RP, and their associations between some GS in adults 60 years of age or older, who attended a geriatric clinic in a university hospital in Mexico. Cross-sectional study in adults aged ≥ 60 years, recruited in 2018, was performed. Participants underwent a comprehensive geriatric assessment, with which spirituality and religious practices model and the diagnosis of GS were obtained. Linear regression analyses were determined to establish the association between RP and GS. We included 128 subjects; mean age was 79 years (SD ± 8). Lowers scores for mass and communion assiduity were associated with worst disability and FP scores (b = - 0.35, P = 0.02; b = - 0.37, P = 0.03). The RP model explained 8% (R2 = 0.083) of the total variance of the depressive symptoms score (P = 0.03). This study showed that the prevalence of RP is higher in Mexican older adults. The RP model can explain 8 and 9% of the variation in dependent variables (depressive symptoms and disability). These results suggest the importance of monitoring RP, as they seem to have a positive impact on health status of the elderly.
