Objective To investigate the level and factors associated with successful aging among retired nurses, and to provide refe-rence for health resource management. Methods A total of 96 retired nurses were selected from three tertiary hospitals in Zhengzhou and were investigated with the Healthy Aging Instrument and the General Self-Efficacy Scale. Results Healthy aging averaged 3.76±0.54, and the dimension of self-care scored the highest, whereas acceptance of aging scored the lowest in the nine dimensions. The total self-efficacy score was 3.40±0.23, and was positively correlated with healthy aging （r=0.629,P＜0.01）. Mul-tivariate linear regression demonstrated that the number of chronic diseases, perceived health status and general self-efficacy were factors influencing healthy aging of the retired nurses （adjusted R square =0.732, P＜0.01 for all）. Conclusion Healthy aging among retired nurses in tertiary hospitals was at moderate to above average level. Hospital managers should pay attention to in-dividual health status of the retired nurses, and utilize these nursing human resources according to their characteristics, thus to achieve the goal of promoting a healthy aging society.
