The results of structural equation model showed that yang- deficiency constitution，qi-deficiency constitution and blood-stasis constitution were correlated with physical exercise (P＜0.05)； damp- heat constitution and qi- constraint constitution were correlated with daily routine(P＜ 0.05)； phlegm- damp constitution and special constitution were correlated with preference for food(P＜ 0.05).
