Methods: 7655 community-dwelling individuals were included in this study. Latent class/profile analysis(LCA/LPA) identified comorbidity profiles, night sleep duration and napping duration trajectories. Generalized additive model with binomial regression assessed the associations between incident asthma with sleep trajectories. Results: During 7-year follow-up, 205 individuals were newly diagnosed with asthma. LPA identified four trajectories of night sleep duration: dominant short(n=2480), dominant healthy-long(n=1405); long decreasing(n=1875); and short increasing(n=1895). We also found three trajectories of napping duration: short increasing(n=3746); stable normal(n=1379); and long decreasing(n=2530); and three comorbidity profiles: dominant heart diseases or risks(n=766); multiple disorders(n=758); and minimal or least disorders(n=6131). Compared with dominant short night sleep duration, three other trajectories were associated with significantly decreasing incident asthma. Minimal or least disorders profile was associated with the significant reduction of new-onset asthma than two other comorbidity profiles in dominant short night sleep duration. Conclusions: Our findings suggested that dominant short night sleep duration trajectory potentially increases incident asthma in Chinese adults.
