140 size did not allow us to perform stratified analysis by medication class. Lastly, the fact that this study presents an associative nature makes it impossible to inflict causality to the observed associations. Perspectives The perception of quality of life has been established as an efficient form of predicting cardiovascular events and survival rate in hypertensive patients. 16 The results of the present study showed that some modifiable factors, such as muscle strength, body mass index, educational level and blood pressure influence the quality of life of these patients, and that has not been sufficiently investigated in the literature. Thus, in practical terms, interventions such as physical exercise and nutritional monitoring that promote previous control of these variables may positively affect the quality of life of hypertensive individuals. Additionally, it is suggested to carry out further studies to evaluate a broader sample of hypertensive patients, including individuals with other morbidities such as diabetes and dyslipidemia, and longitudinal studies evaluating quality of life, as well as its influence, for longer periods. Conclusion In conclusion, it was verified that hypertensive individuals with lower body mass index, higher educational level andmuscle strength presented a better quality of life in the physical domain, while the social aspects have a positive relationship with educational level. Women report worse quality of life in the pain domain compared to men.
