چکیده (انگلیسی):

Objective: To investigate residents' psychological stress factors and research the correlation
between post-traumatic stress disorder (PTSD) and platelet 5-HT concentrations
so as to provide scientific bases for diagnosis and treatment of PTSD and psychological
intervention for people in the disaster area.
Methods: A questionnaire survey of 5 500 residents who have accepted psychological
help was conducted by the emphatic investigation method. While high performance liquid
chromatography was used to detect the platelet serotonin concentration of 100 PTSD
patients and 100 healthy people.
Results: (1) Of the 5 114 cases, 3 167 (61.93%) showed positive results in screening for
psychological stress symptoms, and 399 (7.8%) were tested having apparent PTSD
symptoms. Male and female prevalence showed no significant difference (c2 = −0.380,
P = 0.704). The differences of prevalence between different age groups were statistically
significant (c2 = 381.89, P = 0.000). (2) The differences in the level of platelet 5-HT
between PTSD patients and normal control group were statistically significant.
Conclusions: The typhoon of Hainan Province caused relatively large psychological
problems to the disaster victims. Compared with normal control group, the platelet 5-HT
levels of PTSD patients in the disaster areas are lower. It may be related to incidents
exposure levels, cultural background, religious ideas, social concerns and psychological
rescue of the residents who live in the disaster areas of Hainan.
