Abstract
to evaluate the relationship between leisure-time physical activity and functional capacity change among aged people. we analyzed data of an aged cohort looking for determinants of functional capacity at follow-up. Baseline data were collected between 2007 and 2008 - average follow-up of 3,5 years. A full multivariate linear regression model was built to evaluate functional capacity at the end of the follow-up, controlling for functional capacity at baseline, sociodemographic, health and behavioral characteristics and amount of leisure-time physical activity in the period. final model showed functional capacity independently correlated with age (p<0.001), body mass (p=0.013) and the number of activities of daily living compromised at baseline (p<0.001). Functional capacity improved with increased physical activity but loss statistical significance after adjustments (p=0.384). functional capacity decreases with increased age, increased loss of functional capacity at baseline and increased body mass. Albeit a non-significant association, leisure-time physical activity appears as an important modifiable factor.
Highlights
METHODSThe worlds aged population is increasing substantially at a fast pace, especially in developing countries[1]
The results of this work indicate a significant relationship between BMI and functional capacity (FC), reinforcing the results of other studies[39,40,41] and disagreeing with the results found by Ballesteros, Moreno-Montoya (2018)(9) and Matos (2018) . [42] This relationship can be explained because obesity is related to low physical activity (PA) on the part of the aged[36,43,44] and by the association between excess body fat and the development of chronic diseases[40], most of the times disabling
Our results indicate that an increase in leisure-time physical activity (LTPA) might lead to an improvement in FC, mediated by age and body mass
Summary
METHODSThe worlds aged population is increasing substantially at a fast pace, especially in developing countries[1]. We observe a change in the health profile characterized by the emergence of chronic non-communicable diseases (NCDs), all potentially disabling and directly related to age and lifestyle[4]. The vast majority of the elderly refer some chronic condition that can compromise the ability to perform daily activities, with loss of independence and autonomy and consequent decrease in functional capacity (FC)(5). FC is, an important risk factor for mortality and there is evidence that aged people with a higher degree of dependence in daily life have a greater risk of dying than independent ones[6,7]. Several studies have shown that FC, in turn, is associated with sociodemographic, health and behavioral factors such as age, gender, education, income, number of diagnosis, body mass, smoking, drinking and exercising[8,9,10,11,12]
