Abstract Objective to analyze the sexual function and its association with the sexuality and quality of life of elderly women. Methods this is a cross-sectional web survey study developed with 166 elderly women. Four self-administered instruments were used to obtain biosociodemographic, sexual function, sexuality and quality of life data. The analysis was performed using the Mann-Whitney test, Spearman correlation and linear regression, considering a 95% confidence interval. Results the greatest influence of sexual function was observed in the sexual act dimension of sexuality (β=0.524; [95%CI=0.451-0.597]; p<0.001; R2=54.8%) and between the intimacy facet of quality of life (β =0.501; [95%CI=0.380-0.622]; p<0.001; R2=29.0%). In general, the regression model showed that sexual function remained associated with sexuality (β=0.888; [CI95%=0.749-1.028]; p<0.001; R2=49.1%) and the quality of life of the participants (β=0.352; [CI95%=0.264-0.439]; p<0.001; R2=27.7%). Conclusion and implications for the practice sexual function is associated with the sexuality and quality of life of older women, assuming a directly proportional behavior which, in turn, can become a strategy to add quality to the additional years of life of this population.
