Abstract Despite substantial interest in the development of health behaviors, there is limited research that has examined the longitudinal relationship between physical activity (PA) and smoking trajectories from youth to adulthood. This study aimed to identify trajectories of smoking and PA for males and females, and study the relationship between these trajectories from youth to adulthood.Latent profile analysis was used to identify trajectories of smoking and PA separately for males and females among 3,355 Finnish adults (52.1% females). Participants’ smoking and PA were assessed five to eight times over a 31-year period (3-18 years old at the baseline, 34-49 years at last follow-up). Latent transition analysis was fitted to the data to study relationship between the trajectories of smoking and PA.Five smoking trajectories and four PA trajectories were identified for males and females. Of the PA trajectory groups, the persistently active group were least likely to follow the trajectories of regular smoking and the inactive and low active groups were least likely to follow the rare or non-smoking trajectory group. Likewise, inactive (women only) and low active groups were less likely to belong to rare or non-smokers group. Study suggests that increasing and maintaining PA from youth to adulthood may be in association in preventing and reducing the harmful use of both persistent and increasing smoking.
