What are the effects of the aging of the neuromuscular system on postural stability?

2015

International audience; Aging is frequently associated with a decreased postural stability, essentially after 60 years, leading to an increased risk of falling. In this article we propose to highlight the influence of the aging of the neuromuscular system on postural stability when standing upright. To maintain balance while standing upright, human needs to control the activity of ankle muscles and particularly the plantar flexors. During the aging process, the performance of these muscles are strongly altered. It is commonly observed large deficits in elderly people with history of falls. Some authors reported an inverse correlation between the amplitude of postural sway and the capacity o…

Abstract Background In old age, decline in functioning may cause changes in walking ability. Our aim was to study whether older people who report adaptive, maladaptive, or no walking modifications differ in outdoor mobility. Methods Community-dwelling people aged 75–90 years (N = 848) were interviewed at baseline, of whom 761 participated in the 2-year follow-up. Walking modifications were assessed by asking the participants whether they had modified their way of walking 2 km due to their health. Based on the responses, three categories were formed: no walking modifications (reference), adaptive (eg, walking more slowly, using an aid), and maladaptive walking modifications (reduced frequenc…

Is loneliness associated with mild cognitive impairment in low- and middle-income countries?

2021

Background: Loneliness may be a risk factor for mild cognitive impairment but studies on this topic are scarce, particularly from low- and middle-income countries (LMICs). Therefore, the aim of the present study was to investigate the association between loneliness and mild cognitive impairment (MCI) in six LMICs (China, Ghana, India, Mexico, Russia and South Africa). Methods: Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analysis and meta-analysis were conducted t…

Older adult psychopathology: international comparisons of self-reports, collateral reports, and cross-informant agreement

2020

ABSTRACTObjectives:To conduct international comparisons of self-reports, collateral reports, and cross-informant agreement regarding older adult psychopathology.Participants:We compared self-ratings of problems (e.g. I cry a lot) and personal strengths (e.g. I like to help others) for 10,686 adults aged 60–102 years from 19 societies and collateral ratings for 7,065 of these adults from 12 societies.Measurements:Data were obtained via the Older Adult Self-Report (OASR) and the Older Adult Behavior Checklist (OABCL; Achenbach et al., 2004).Results:Cronbach’s alphas were .76 (OASR) and .80 (OABCL) averaged across societies. Across societies, 27 of the 30 problem items with the highest mean ra…

Rejoinder to Chambers' Comments

1995

RÉSUMÉLes commentaires du professeur Larry Chambers soulèvent des enjeux qui méritent réflexion. Il préfêre le terme «théorie» à celui de «modèle»; il y a plusieurs définitions du concept de modèle et, en conséquence, absence de concensus. Pour moi, le modèle est une métaphore qui guide la recherche de théorie. Quand les variables sont très nombreuses, comme en épidémiologie écologique, le modèle permet au chercheur de construire une séquence d'évenéments qui aide à la compréhension du phénomène étudié. Chambers a raison: je n'ai pas essayer de définir des facteurs de risque spécifiquement épidémiologiques et écologiques. En pratique, les facteurs écologiques du vieillissement restent en ar…

Functional Capacity and Difficulties in Activities of Daily Living From a Cross-National Perspective.

2022

Objectives: This study investigated whether physical and cognitive functioning predicts developing difficulties in basic or instrumental activities of daily living (ADL/IADL), and whether country-level factors moderated the associations. Methods: 69,227 adults aged 50+ from 19 countries were followed for up to 14 years. Cox regression and meta-regression analyses were used. Results: Higher grip strength was associated with a 45% lower risk of developing ADL limitations and a 47% lower risk of IADL limitations. The corresponding values were 22% and 23% for peak flow, 20% and 23% for word recall, and 20% and 24% for temporal orientation. The associations were similar and statistically signif…

Physical Activity Tracker Application in Promoting Physical Activity Behavior among Older Adults : A 24-month Follow-Up Study

2022

Objectives To investigate whether and how PA tracker application use supports PA behavior among older adults during the first 24 months of use. Methods: The changes in PA levels (i.e., time spent in different PA intensities) and between PA categories (i.e., low, moderate, or high based on total PA) were examined between three different time points: before taking the application into use (t0), after 12 months of use (t1), and after 24 months of use (t2). The data was collected by using the International Physical Activity Questionnaire modified for the elderly (IPAQ-E). Results: A statistically significant increase was observed in walking (χ2 (2) = 29.741, p < .001), moderate PA (χ2 (2) =…
