To analyze the concept of healthy aging and propose the development of a nursing diagnosis METHODS: Concept analysis using the method proposed by Walker and Avant FINDINGS: Four bibliographic databases were searched, and 36 articles were included in the analysis. Seven antecedents, seven attributes, and three consequences for "healthy aging" were identified. The concept analysis supported the development of the new nursing diagnosis "readiness for enhanced healthy aging," which can assist nurses in implementing actions aimed at promoting the health of older adults. The establishment of a nursing diagnosis may provide nurses the opportunity to implement interventions that promote the maintenance of functional and cognitive capacity, psychological and spiritual well-being, and social engagement, aiming at healthy aging with high quality of life.
