Subjects and methods: A cross-sectional study was done in Vietnamese submariners. Anxiety was assessed by Spielberger questionnaire, depression was assessed by Beck questionnaire. These tests were conducted in submariners a day before training at sea. Cortisol level was assessed before and after training at sea and automatically analysed by Architect Plus CI16200 Biochemical Analyser. Result: Submariners suffer from T-Anxiety at moderate level with mean score 36.47 ± 6.96. Prevalence of moderate T-Anxiety was 70.7%. The mean score of depression was 3.89 ± 3.59, the depression was found in 51.6% of submariners. The prevalence of depression among job groups were significantly defferent (p 0.05 Table 1 showed that the anxiety level of submariners at particular time was low with mean score 21 ± 9.76. The number of submariners with mild anxiety was 82.1%. There was no case of pathological anxiety. The differences of S-Anxiety among job groups were not significant (p > 0.05).
