PURPOSE: 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.

METHODS: 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).

RESULTS: 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 < 0.001], mental health (OR 1.12, p < 0.001), self-rated health (OR 2.43, p < 0.001), group activities participation (OR 1.43, p = 0.037), being socially supported (OR 1.58, p = 0.024), and not reporting financial difficulties (OR 1.76; p = 0.036).

CONCLUSIONS: Using different cut-offs to defining favorable QoL results in important changes in the number and type of significant health, economic and social determinants. A cut-off between 'good' and 'very good' appears to best reflect the multidimensional nature of QoL.
