Abstract
Background: Previous cohorts studied the association of various types of physical activities with the incidence of cognitive disorders. The objective of this work was to analyze the association of leisure, domestic and professional physical activities with mild and moderate cognitive disorders in older people living in the community.Methods: We used retrospective data from the “FRéLE” (FRagilité: étude Longitudinale de ses Expressions) a longitudinal and observational study. Data collected included socio-demographic variables, lifestyle and health status. Cognitive disorders were assessed using the Montreal Cognitive Assessment (MoCA). Two cut-offs of MoCA were used to analyze mild and moderate cognitive disorders. Physical activity was assessed by the Physical Activity Scale for the Elderly (PASE) structured in three sections: leisure, household, and professional activities. Spline and logistic regression models were used to estimate the risk of cognitive disorders.Results: At baseline, 428 participants (for study of mild disorders) and 1,271 participants (for study of moderate disorders) without cognitive disorders were included in the analysis. The mean ages were 74 and 78 years, respectively. After a 2-year follow-up, we found mild cognitive disorders in 154 participants (36%) and 71 cases of moderate cognitive disorders (5.6%). In multi-adjusted logistic models, domestic activities were associated with cognitive disorders, but not leisure and professional activities.Conclusion: We found an inverse relation between domestic sub-score and cognitive disorders defined by MoCA < 18. With a specific questionnaire and quantitative information on the type of activities, this study contributed to the debate on the beneficial effects of physical activity on cognition.
Highlights
The advancing age of a population leads to an increase in age-related pathologies, including neurodegenerative diseases
Of the 1,643 participants, 1,124 (68.4%) were not included because they were considered as having mild cognitive disorder (MoCA < 27) at the baseline
Some 24.8% were in a state of frailty according to the Groningen Frailty Indicator (GFI), and 9.6% according to the Fried scale (35.8% in prefrailty)
Summary
The advancing age of a population leads to an increase in age-related pathologies, including neurodegenerative diseases. Aging should not be synonymous with poor health, for age-related diseases can be avoided or delayed. The importance for older adults to carry out physical activities (PA) even during the ongoing COVID-19 pandemic is well-known. This practice is important because its health benefits are well established [1]. Previous cohorts studied the association of various types of physical activities with the incidence of cognitive disorders. The objective of this work was to analyze the association of leisure, domestic and professional physical activities with mild and moderate cognitive disorders in older people living in the community
