Abstract：Objective To reveal the correlation of sleep quality with sleep rhythm, anxiety and depression in armymen with insomnia and to discover the main cause of insomnia of military out-patients. Methods Seventy cases of patients were enrolled, including 25 males and 45 females aged from 28 to 52 with an average of (38±15. 2). Correlations between Pittsburgh sleep quality index (PSQI), morningness/eveningness questionnaire (MEQ), Hamilton anxiety index (HAMA), Hamil-ton depression scale ( HAMD) were studied in patients with insomnia from January 2014 to April 2015. Results PSQI score was 0 to 21 points with an average of (12. 0±5. 2). Each factor score was as fo-llows respectively:factor 1 ,subjective sleep quality (1. 8±1. 0), factor 2, sleep latency (2. 1±1. 0), factor 3, sleep duration (1. 6±1. 0), factor 4, habitual sleep efficiency (1. 8±1. 2), factor 5, sleep disorder (1. 6±0. 7). factor 6,use sleep medicine (1. 0±1. 3), factor 7, daytime dysfunction (2. 0± 1. 1). MEQ score was 44—76, with an average of (61. 3±7. 6). The classification of MEQ was as fo-llows, absolutely morningness type 10 cases ( 14. 3%) , moderately morningness type 25 cases ( 35. 7%) , intermediate type 32 cases ( 45. 7%) , moderately eveningness type 3 cases ( 4. 3%) , ab-solutely eveningness type 0 cases (0). HAMA score was 5—42, with an average of (17. 7±9. 0). HAMD score was 3—46, with an average of (20. 3±10. 8). By linear regression analysis,there was no relationship between the insomnia MEQ, PSQI and its 7 factors (P>0. 05). HAMA, HAMD PSQI and its 7 factors are related (P<0. 05). Conclusion Insomnia of military outpatients has nothing to do with sleep rhythm characteristics, but is definitely related to their anxiety and depression status. It’s important to do the anxiety and depression scale before prescription of sleeping pills. Antianxiety and antidepressant treatment might be necessary as an assistant therapy of insomnia.
