Aerobic or strength training and flexibility activities and mild cognitive impairment: CETI cohort

Abstract Background Previous studies have been notably criticized for not studying the different types of physical activity. The objective of this work was to examine the association between types of physical activity and cognitive decline in older people. Methods This is a sub-group analysis from the CETI cohort, a multicenter prospective study conducted by the Canadian Emergency Team Initiative Program (CETIE), between 2011 and 2016. Participants were community-dwelling seniors aged ≥ 65 years, consult emergency services for minor injuries with follow-up at 3 and 6 months. Physical activity was assessed by the RAPA (Rapid assessment of Physical activity), which describes the level of aerobic activities and the overall level of muscle strength and flexibility activities. The cognitive status was assessed with the Montreal Cognitive Assessment (MoCA) and the Telephone Interview for Cognitive Status (TICS), using their current cut-offs (MoCA <26/30 and TICS < = 35/50) for mild cognitive impairments (MCI). Logistic regression, COX models and splines were used to examine the association between the type of physical activities and the onset of cognitive impairment. Results At inclusion, 281 individuals were free of MCI, or 43.8% of the total sample, with an average age of 73 years. During follow-ups, MCI appeared in 31.7% of participants initially free of it. The risk of MCI was lower with higher muscular strength & flexibility physical activities (HR = 0.84 [0.70-0.99]), while the relationship with aerobic physical activities was not significant. Conclusions These results showed a potential link between strength & flexibility activities and cognitive impairments, but not with aerobic physical activities. Further analyses are needed to examine whether these relationships persist as a function of the adjustment variables, or statistical methods. This study contributes to the debate on the evaluation of physical activity in the elderly, and its link with neurodegenerative diseases. Key messages This study analyzed the link between types of physical activity and mild cognitive disorders. The aim is to put in place preventive policies of aging, specially in neurodegenerative diseases. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.

The Impact

Abstract Background Given increasing incidence of cognitive impairment and dementia, further understanding of modifiable factors contributing to increased healthspan is crucial. Extensive literature provides evidence that physical activity (PA) delays the onset of cognitive impairment; however, it is unclear whether engaging in PA in older adulthood is sufficient to influence progression through cognitive status categories. Method Applying a coordinated analysis approach, this project independently analyzed 14 longitudinal studies (NTotal = 52 039; mean baseline age across studies = 69.9–81.73) from North America and Europe using multistate survival models to estimate the impact of engaging in PA on cognitive status transitions (nonimpaired, mildly impaired, severely impaired) and death. Multinomial regression models were fit to estimate life expectancy (LE) based on American PA recommendations. Meta-analyses provided the pooled effect sizes for the role of PA on each transition and estimated LEs. Results Controlling for baseline age, sex, education, and chronic conditions, analyses revealed that more PA is significantly associated with decreased risk of transitioning from nonimpaired to mildly impaired cognitive functioning and death, as well as substantially longer LE. Results also provided evidence for a protective effect of PA after onset of cognitive impairment (eg, decreased risk of transitioning from mild-to-severe cognitive impairment; increased likelihood of transitioning backward from severe-to-mild cognitive impairment), though between-study heterogeneity suggests a less robust association. Conclusions These results yield evidence for the importance of engaging in PA in older adulthood for cognitive health, and a rationale for motivating older adults to engage consistently in PA.

Abstract Background Previous cohorts have been notably criticized for not studying the different type of physical activity and not investigating household activities. The objective of this work was to analyse the relation between physical activity and cognitive decline in older people living in community. Impact of type of physical activity on the results has been realised. Methods The study used data from the longitudinal and observational study , FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: MMSE (Mini-Mental State Examination)and MoCA (Montreal Cognitive Assessment). Physical activity was assessed by the PASE (Physical Activity Scale for the Elderly). This tool is structured in three sections: the leisure activity, the domestic activity and the professional activity. Logistic regressions and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results At baseline, the prevalence of cognitive disorders was 6.9% according to MMSE. In total, 1326 participants without cognitive disorders were included in the analysis. The mean age was 77.4 years, and 52.1% of the participants were women. After a 2 years long follow-up, we found cognitive disorders on 92 participants (6.9%). Physical activity at baseline is lower in older adults for whom cognitive decline was observed after two years of follow-up. Subclass analyses showed that leisure and domestic activities were associated to cognitive decline, but not professional activities. Conclusions Analysis showed a relationship between cognitive disorders and type of physical activity. The current study will be completed by the MoCA for mild cognitive impairment. These findings compared to other ongoing studies will contribute to the debate on the beneficial effects of physical activity on cognition. Key messages The work allowed us to analyze the link between the different types of physical activity and mild to severe cognitive disorders. The aim is to put in place preventive policies of aging. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.

The Impact

The aging of the Western society has become one of the key issues in research. Lately research has shown relationship between improvement in cognitive functioning and involvement in physical activities. The aim of the study was to examine the impact of different types of physical activities on executive functioning. Overall 30 seniors aged from 65 participated in a two-day study. They were divided into three groups per their life-style – aerobic activity, strength training and sedentary. Results indicated differences between the groups in cognitive efficiency (F = 6.791, p < 0.01) and working memory (F = 6.179, p < 0.01) as well as the inhibition of attention (F = 4.311, p < 0.01). The mean scores were higher in the aerobic group. The results indicate that involvement in aerobic physical activity might lessen the decline in executive functioning in seniors.

Objectives: Previous research on cognitive impairment and health behaviors has focused largely on how health behaviors affect cognition; rarely has it examined whether cognitive impairment affects health behaviors. The purpose of this study was to examine the impact of cognitive impairment on engagement in health behaviors among older adults. Methods: The study sample included 19,644 adults aged 50 or older from the Health and Retirement Study 1995-2012 surveys. We used mixed-effects logistic regression to analyze the influence of cognitive impairment, measured using the Telephone Interview for Cognitive Status, on the engagement of health behaviors including physical activity, smoking, and drinking. Results: Cognitive impairment without dementia [CIND] (OR = .84, 95% CI = .80-.89) and dementia (OR = .68, 95% CI = .61-.75) were associated with a lower likelihood of engaging in regular vigorous physical activity during longitudinal follow-up, after adjusting for covariates. CIND or dementia was not significantly associated with the likelihood of smoking or alcohol consumption. Conclusions: CIND and dementia are risk factors for physical inactivity among older adults. Promotion of regular physical activity should be an essential component of health promotion programs for persons with cognitive impairment.

The Impact

More minutes of physical activity (PA) accumulated during a day are associated with a lower risk of diabetes mellitus type 2. However, it is less known if distinct dimensions of PA can produce a different protective effect in the prevention of prediabetes. The aim of this study was to analyze the impact of work and recreational PA on prediabetes among U.S. adults during the period 2015–2016 using the National Health and Nutrition Examination Survey (NHANES) database. Individuals (n = 4481) with hemoglobin A1c (HbA1c) test values of 5.7% to 6.4% were included. A logistic regression multivariate-adjusted analysis was conducted to estimate the association between the odds ratios (ORs) and 95% confidence intervals (CIs) of prediabetes, with work and recreational PA. The prevalence of prediabetes among U.S. adults was lower in physically active individuals both at work (~24%) and recreational (~21%) physical activities compared to individuals who were not physically active (27 to 30%). Individuals lacking practice of recreational PA had a high risk of prediabetes (OR = 1.26, 95% CI: 1.080 to 1.466). PA may be a protective factor for prediabetes conditions depending on gender, age, ethnic group, waist circumference, and thyroid disease.

Abstract Background Few previous cohorts have studied the different type of physical activities and the degree of cognitive decline. The objective of this work was to analyze the leisure, domestic and professional activities with mild and moderate cognitive disorders in older people living in community. Methods The study used data from the longitudinal and observational study, FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment). MoCA was used with two cut-offs (26 and 17) so as to define mild and moderate cognitive disorders Physical activity was assessed by the PASE (Physical Activity Scale for the Elderly), structured in three sections: leisure, domestic and professional activities. Spline and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results At baseline, 1623 participants were included and the prevalence of cognitive disorders was 6.9% (MMSE) and 7.2% (MoCA), mild cognitive disorders was 71.3%. The mean age was 77 years, and 52% of the participants were women. After a 2 years long follow-up, we found 6.9% (MMSE) and 6% (MoCA) cognitive disorders on participants. Analyses showed that domestic activities were associated to cognitive decline (HR = 0.52 [0.28-0.94] for MMSE and HR = 0.48 [0.28-0.80] for MoCA). No association were found with leisure and professional activities, and no spline were significant with mild cognitive disorders. Conclusions Analysis showed a relationship between cognitive disorders and type of physical activity, thanks to the use of specific questionnaire of elderly and two global test of cognition. These findings will contribute to the debate on the beneficial effects of physical activity on cognition. Key messages This work allowed to compare two test of cognition and their link with physical activity. It contributes to the debate on the beneficial effects of physical activity on cognition. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.

The Impact

Physical activity has an unquestionable impact on broadly understood human health. One interesting issue related to this is the importance of movement on mental health and cognitive functioning. Research shows that regular physical activity improves the cognitive functioning of adults and people with mental disorders. Regular physical activity can be an important and powerful protective factor in cognitive impairment and dementia in the elderly, and exercise is an important non-pharmacological treatment for mild cognitive impairment or neurodegenerative diseases. This study aims to present the impact of physical activity on selected cognitive functions in physically active women over 60 years of age. The research was carried out in a group of 110 generally healthy women from the area of western Poland over 60 years of age, who were divided into four groups based on the intensity of their physical activity. A pedometer (sport watch) and a physical activity diary were used to measure physical activity. Body Mass Index was assessed. Selected cognitive functions were assessed using the MMSE test, motor and psychomotor skills were measured, and Luria’s auditory memory test and recall test, a clock drawing test, and a GDS test were performed. There were statistically significant relationships between the level of physical activity and the effectiveness of cognitive processes. These results show that about 5000 steps a day is enough to see a positive effect on the mental health and cognitive functioning of this group of the elderly population. The women had an average BMI of 28.1 ± 4.7. BMI, indicating an overweight condition (over 30 kg/m2), was observed in 31% of women. The results of this study lead the authors to conclude that physical activity positively influences cognitive function and can be recommended for all seniors who do not have other serious comorbidities that would prevent them from playing sports.
