Objective To investigate the chronic insomnia incidence and traditional Chinese medical (TCM) constitution of students in Southern Medical University, in order to discover the correlation between chronic insomnia and TCM constitution. Methods A survey by means of the TCM Constitution Scales, the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and the Deep Sleep Scale (DSS) in 110 participants studying in Southern Medical University between September 2009 and July 2014 was conducted. We analyzed the characteristics of chronic insomnia in subjects of qi-deficiency type and gentleness type. Results A total of 115 questionnaires were sent out, and 110 were recovered with a recovery rate of 95.65%. All the 110 questionnaires were useful and the effective rate was 100%. There were 34 cases of gentleness type and 44 cases of qi-deficiency type in the 110 participants. It was found that qideficiency type got significantly different scores for all the three types of scales, compared with gentleness type (P＜ 0.01) . Meanwhile, qi-deficiency type showed significant differences in terms of sleep quality, sleep time, sleep disorder and daytime dysfunction from gentleness type (P＜ 0.05) . We also found that the incidences of shallow sleep and insomnia for qi-deficiency type were higher than those for gentleness type (P=0.002, 0006) , respectively. Finally, it was detected that the level of insomnia for qi-deficiency type was higher than that for gentheness type (P＜ 0.01) . Conclusions This study has revealed that there is a statistically significant association between qi-deficiency type and chronic insomnia. It is suggested that further research should be conducted for cure of chronic insomnia from the perspective of changing TCM constitution.
