Association between per capita income and supine to stand task performance in older adults

Introduction: Socioeconomic status influences on Brazilian elderly population, as well as the morphological and functional repercussions derived from the aging process are increasingly taking place in interdisciplinary sphere of studies related to gerontology. The associations of variables from human domains amplify the discussion in the field of health sciences and exact sciences. Therefore, the objective of this study was to associate per capita income and supine-to-stand task performance in the elderly. The sample consisted of 170 elderly people, free of dementia or any metabolic, cardiac or osteomioarticular disease that prevented them from performing supine-to-stand task, without assistance. Per capita income was collected through a questionnaire and the motor task was filmed and analyzed by computational software to determine the time required to perform the movement. The reliability of the filming decoding was calculated from the Intra-Class Correlation Index (r = 0.99; p <0.001). The association between the variables were calculated using the Qui-Square test and the significance level adopted was p ≤ 0.05. The correlation between supine-to-stand task performance and per capita income was negligible (p = 0.580) and did not reach statistical significance. The main results suggested that the motor competence screening must be executed independently of per capita income
