Methods: a descriptive study and qualitative approach. The study was conducted with 18 Family Health Strategy nurses from the city of São Carlos. Data were collected through semi-structured interviews and analyzed through thematic analysis. The study was approved by the Research Ethics Committee.
Results: the data revealed that nurses had difficulties to conceptualize health promotion, and it is common to describe the definition of disease prevention.
