Abstract
DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n2p139 The registration or insertion of older adults in Community Physical Activity Programs does not guarantee their stay over time. The purpose of this study was to analyze the length of stay of elderly in a Community Physical Activity Program and associated factors. This epidemiologic observational study of retrospective cohort performed in Aracaju City, Brazil, included a sample of 526 older adults (477 females) aged 66.4 ± 5.4 years. To characterize the profile and length of stay of individuals, descriptive statistics was used. To analyze the length of stay, the Kaplan-Meier non-parametric survival, estimator was used. To verify the association between variables in the observed time, the Cox regression model was applied. Inverse ratio equation (1/OR) was used to facilitate the understanding of significant values when necessary. In all analyses, 95% confidence interval and p≤0.05 were used. In the first three months, stay rate of 58.1% (95% CI = 54.6 - 61.3) was observed, with a risk estimative = 41.82%. Females presented a 45% chance of stay (OR = 0.69; 95% CI = 0.51 – 0.93) and individuals identified with osteoporosis had 32% more chances of stay (OR = 0.74, 95% CI, = 0.60-0.91). Only 1% of subjects remained until the end of the cohort. The stay rate was low throughout all series; the period with higher quitting rates was the 3rd and the 12th months, being associated with the female stay sex and undiagnosed osteoporosis.
Highlights
The World Health Organization (WHO) describes the phenomenon of population aging as one of the factors that need attention in terms of health and public policies[1]
In contrast to other countries, in Brazil, there is a scenario in which phenomena known as epidemiological transition and demographic transition occur practically at the same time, suggesting a framework of actions aimed at the prevention and control of chronic-degenerative diseases, as well as those aimed at the rapid population aging[2,3,4]
6.5% were classified as censors, that is, subjects that at some point quitted participation in the program, but who returned to it during the observation period
Summary
The World Health Organization (WHO) describes the phenomenon of population aging as one of the factors that need attention in terms of health and public policies[1]. In 2005, the Brazilian Ministry of Health began to encourage projects that offered physical activity to improve the quality of life of the population, which in 2006 became the axis of the National Health Promotion Policy (PNPS)[5] Interventions in these programs often seem to lead to high turnover of participants due to the lack of specificity of intervention methods for age groups and special groups[6]
