The World Health Organization defines quality of life as an individual's perception of his social position in the cultural context and value system in which he lives, and in relation to his own goals, expectations and standards. The world's population is rapidly aging, therefore population aging is becoming one of the most significant social transformations of the 21st century, with implications for almost all sectors of society. The main factors that determine the quality of life of the elderly are considered to be: age, subjective health status, finance, leisure activities and fairness of health inequality. In the period from March to June 2024, a cross-sectional study was conducted, which attempted to examine the level of quality of life of elderly residents in Varaždin County, using a short questionnaire on the quality of life in the elderly (OPQOL-BRIEF), and to show the determinants that people perceive as necessary for their quality of life. 200 elderly people participated. Three latent factors were identified in the data analysis - general life satisfaction, physical health and independence, and financial security or emotional stability. The analysis showed a statistically significant difference in the perception of the quality of life among different groups according to finances, gender, and educational level. So, men more often accept life circumstances and feel greater financial stability compared to women. People who receive a satisfactory amount of monthly pension rate their quality of life as better compared to those who do not receive it (a low amount). People with a higher level of education experience joy more often, are more active in society and rate their health as better. To improve the quality of life of the elderly, a multidisciplinary team is needed - a doctor, nurse, physiotherapist, psychologist and others. The role of the master's degree in nursing is to assess, manage, measure and monitor the progress of the quality of life of the elderly. She is in charge of education, the implementation of preventive programs, as well as the coordination of all other aspects necessary to ensure an adequate quality of life for the elderly, because the only correct approach is a holistic, individualized approach to each elderly person.
