A Survey Of Psychosomatic Symptoms In Occupational Mercury Poisoning Patients

ObjectiveChina is a big manufacturing country. With the rapid socio-economic development in recent years, occupational health still cannot be ignored because of the limitations of the economic level, the private enterprise, the rise of new types of jobs, new industries, new poisons, the existence of the occupational hazards passed on other issues, and so on. The thesis referred aims at acquaintance of the occupational hazards existed in the production process for adverse effects on workers’ health, which can provide references for future comprehensive treatment of patients with occupational poisoning and improve the efficacy.Material and methodsThe occupational mercury poisoning patients conforming to occupational mercury poisoning diagnostic criteria (GBZ89-2007) were enrolled, the healthy examination volunteers during the corresponding period were served as a control group. We use questionnaire to survey psychosomatic symptoms (Symptom rating scale SCL90), sleep quality (Pittsburgh Sleep Quality Index questionnaire PSQI), anxiety score (Self-Rating Anxiety Scale, SAS) and depression score (Self-Rating Depression Scale, SDS). The sleep quality and anxiety depression state were compared and analysed, basing on the SAS and SDS score, we intercompare the sleep state among the subgroups in occupational mercury poisoning patients and compare with the control, to analyse the sleep state in all groups. Statistical analysisMean and standard deviation were calculated for all measurements. All statistical analyses were performed using the SPSS software, version13.0. Data were analyzed by Fisher’ s exact probabilities test or Independent-Samples T test. Statistical significance was set at P<0.05.Result1. General information: the experimental group:145cases (male63, female82), average age is22±2.58, average length of service is2.0±1.54; the control:59cases (male28, female31), average age is23±2.35, average length of service is2.3±1.9.2. Evaluation of psychosomatic symptoms in occupational mercury poisoning patients:the experimental group patients with symptoms of somatization, depression, anxiety, fear and other symptoms compared with control group significant difference (p<0.05). Tip experimental group was accompanied by psychological somatic symptoms.3. Evaluation of anxiety depression in occupational mercury poisoning patients:the experimental group:the SAS raw score is29.43±15.24, among them18for SAS score≥40, positive incidence is12.41%; The control:the SAS raw score is26.10±11.55,2for SAS score>40, positive incidence is3.39%; All above have significant difference (p<0.05). The experimental group:SDS raw score is31.29±13.32, among them10for SDS>40, positive incidence is3.39%; the control:SDS raw score is26.51±13.91(P<0.05), among them4for SDS>40, positive incidence is6.90%(P>0.05). It reveals more anxiety depression disorder in occupational mercury poisoning patients.4. Sleep Quality in occupational mercury poisoning patients:in Sleep Quality Index questionnaire, such as Sleep Quality, Sleep Disorder, Day Function Disorder and PSQI score shows significant difference among the experimental group and the control (P<0.05). While the Sleep Latency, Sleep Time, Sleep Efficiency, Hypnotic reveals no significant difference (p>0.05), which indicates more sleep disorder in occupational mercury poisoning patients. 5. The indicators such as Sleep Quality, Sleep Disorder, Day Function Disorder and PSQI score shows significant difference among the125cases of non-anxiety depression occupational mercury poisoning patients and the control(P<0.05). While other4fields including Sleep Latency, Sleep Time, Sleep Efficiency, Hypnotic reveals no significant difference (p>0.05). In20anxiety depression occupational mercury poisoning patients cases,6fields including Sleep Quality, Sleep Latency, Sleep Time, Sleep Efficiency, Sleep Disorder, Day Function Disorder and PSQI score shows significant difference to the control(p<0.05). Only the Hypnotic reveals no significant difference(p>0.05). All indicators including Sleep Quality, Sleep Latency, Sleep Time, Sleep Efficiency, Sleep Disorder, Day Function Disorder, Hypnotic and PSQI score shows significant differency among the anxiety/depression occupational mercury poisoning patients and the non-anxiety depression occupational mercury poisoning patients (P<0.05).Conclusions1. Occupational mercury poisoning patients shows more anxiety and depression emotional disorder.2. Occupational mercury poisoning patients have more sleep disorder, major manifested in Sleep Quality, Sleep Disorder, Day Function Disorder and PSQI score.3. The state of anxiety and depression worsen the sleep disorder in occupational mercury poisoning patients.
