Attitude towards aging (AtA) is related to young adults' future expectations, which could also influence their current behaviors. Impulsivity is a risk factor related to a number of health concerns in young adulthood. The current study investigated how AtA was related to young adults' impulsive behaviors and explored whether future orientation was a mediator. A total of 371 Chinese young adults were recruited and completed a survey on their demographic characteristic, AtA, consideration of future consequences (CFC) and impulsiveness. The results showed that AtA had a significant negative curvilinear relationship with impulsiveness (β = -.02, p = .03). Notably, participants with very positive or very negative AtA both reported lower impulsiveness level compared with those who were in the middle. Furthermore, CFC mediated this curvilinear relationship (β = -.02, p = .03). There was a significant curvilinear relationship between AtA and CFC (β = .08, p < .001), with both very positive and very negative AtA related to higher levels of CFC. Higher CFC was further related to lower impulsiveness. The results suggest that young adults holding very positive or very negative AtA are both concerned about their future and are more capable of restraining from impulsive behaviors. The inverted U‑shaped pattern between AtA and young adults' impulsiveness provides a new perspective to understand the role of AtA in early adulthood. Future studies could further investigate the different motives driving the future orientation for young adults with either positive or negative AtA.
