[Functional capacity in elderly longevity: an integrative review].
This is an integrated literature review intended to get to know the Brazilian scientific production regarding the functional capacity of the elderly. BDENF, LILACS, MEDLINE and SciELO databases were consulted in the sampling period from January, 2001, to September, 2010. Eight articles were selected with nursing professionals (4) as the main authors of such publications. Publication year of the articles is between 2006 and 2010, with predomination of quantitative research focused on the multidimensionality of the elderly. Questionnaires and scales were used to assess the functional capacity of the elderly and constraining factors for its performance were also indicated. Scientific studies on the theme are incipient, which evidences the need for further research aiming to improve the quality of life ofstudy took place in the Eastern Cape, a province with the lowest per-capita GDP nationally, and very limited social service access \[[@R32]\]. Within a health sub-district constituting urban, rural, and peri-urban settlements, all 53 facilities providing adolescent antiretroviral therapy (ART; hospitals, primary care clinics, and community health centres) were visited and included in the study.

To prevent sampling bias towards those attending healthcare, adolescents were not interviewed in clinics, but were traced to 180 communities and interviewed in their homes and schools. It was important to avoid risk of stigma or identification of HIV-positive status from participation in the research. Consequently, the
