Résumé
The aim of this study was to identify modifications in health, economic and social determinants of quality of life (QoL) in community-dwelling older adults when using different cut-offs to defining favorable QoL. Data of year 2011 annual assessment in 1003 older men and women from the Lc65+ cohort study were used. Overall QoL was self-rated as 'excellent,' 'very good,' 'good,' 'fair,' or 'poor.' To identify significant health (self-rated health, SF-12v2 physical and mental health), economic (financial situation), and social (living with others, being socially supported, emotional support, group activities participation) determinants of QoL, a cut-off was set at three different positions to define favorable QoL on the 'excellent' to 'poor' spectrum: at least 'good' (model 1); at least 'very good' (model 2); and 'excellent' only (model 3). In all three models, bivariable analyses indicated significant associations between QoL and at least one variable from each health, economic, and social dimension. In multivariable analyses, only health-related variables remained significantly associated with QoL in model 1. Model 3 additionally retained financial situation. In model 2, QoL was positively associated with physical health [odds ratio (OR) 1.10, p
