RESUMO
A cross-sectional study was conducted with 139 family caregivers in two community health center areas in the city of Belo Horizonte, located in the southeastern state of Minas Gerais, Brazil. The purpose of the study was to analyze the relationship between level of care dependency and quality of life (QOL) of family caregivers. A socio-demographic questionnaire, the Barthel Index for assessing patients' care dependency level, and the World Health Organization's Quality of Life-BREF (WHOQOL-BREF) for evaluating family caregivers' QOL were used. Patients' care dependency level was not significantly associated with family caregivers' QOL. However, the QOL decreased when family caregivers had chronic disease and were dependent on public health care services, and increased when they received caregiver education and practiced a leisure activity. These factors are modifiable or controllable; therefore, family health nurses have an important role in formulating strategies to support family caregivers, especially those related to health education aimed at health care, health promotion, control, and prevention of diseases.
