摘要
目的 研究船员航行时患病率与心理疲劳之间的关系。方法 调查航行期间船员的患病率 ;在航行前及航行的中期、后期对抽样的 40名船员应用 SCL - 90量表进行情绪状态调查 ,并测量其外周血肾上腺皮质激素的含量。结果 航行期间船员的患病率升高 ,第 2周最高 ,为航行前 4倍 ,并呈先升后降的趋势 ,航行第 1、2、3、4周平均患病率为航行前的 3.1、4.1、2 .5、1 .5倍。情感状态、肾上腺皮质激素含量变化与患病率类似。结论 不良精神因素影响了船员机体的抵抗力 。
Objective To explore the relationship between morbidity and mental fatigue in seamen during voyage.Methods 40 seamen were sampled.The contents of the seamen′s adrenal cortical hormone in peripheral blood were measured and their emotional state investigated with symptom checklist 90(SCL 90)before,in the middle and at late period voyage.Results Seamen′s morbidity was raised and had a tendency to increase at first,then decreased during the course of voyage.The average morbidity of the lst,2nd ,3rd and 4th week was 3.1,4.1,2.5 and 1.5 times of that before voyage respectively.Similar changes were observed with emotional state and the content of adrenal cortical hormone.Conclusions Various psychological factors during the voyage were shown to affect the seamen′s body resistance,which could be an important cause resulted in the increase of seamen′s morbidity.
