Abstract

Smoking is a serious global public health problem. Its serious consequences arose from smoking and the ability to quit it are closely related to age. Personal determination and education level usually play important roles in quitting smoking. In order to capture such characteristics, we developed a novel age-structured smoking dynamical model. By defining the smoking generation number R0, the local stability, global stability of the boundary equilibrium and endemic equilibrium are obtained using Lyapunov functions. The uniform persistence, as well as the well-posedness and asymptotic smoothness of the solutions are also studied. Sensitivity analyses show that the lower the age of onset of smoking and the higher the determination to stop, the greater the likelihood of quitting smoking and numerical studies support the theoretical results.
