title: Correlates of above-average cognitive performance among older adults: the SABE study.
abstract: This study aimed to identify factors associated with optimal global cognitive performance among older adults in the city of Sao Paulo, Brazil. A cross-sectional study was carried out with a sample of community-dwelling older adults who participated in the SABE Study (Health, Well-Being and Ageing) in 2006. The dependent variable was cognitive performance, categorized as "normal" or "optimal". The independent variables were socio-demographic data, lifestyle and health conditions. Data analysis involved descriptive statistics, followed by multiple logistic regression (significance set at 5%). Optimal cognitive performance was found in 28.4% of the sample, representing 730,051 older adults. Optimal performance was associated with a younger age, a report of no difficulties regarding instrumental activities of daily living, non-abusive alcohol intake, self-rated income sufficient to meet one's daily needs and contact with family and friends. Optimal cognitive performance among older adults is associated with conditions favoring participation and independence.
