Using t test or chi square test to compare the stress related psychological behavior between different demographic characteristics and the difference between the psychological behavior and the The distribution of genotypes and alleles. Structure equations were constructed with Amos5.0, and the relationship between (SOCIAL) environment and psychological stress was analyzed. The relationship between genetic polymorphism and the risk of psychological stress was analyzed by single factor and multiple factor Logistic regression analysis (SOCIAL). Results (1) the score of the total life event scale was fifty. P50) was 27. There were 293 people with a total score of more than 20. The positive rate was 50.60%.. The frequency of family events, work events and social events were 75.82%, 11.57% and 24.35%., respectively, were 234, 40.41%, 22.97%, 96 (16.58%). (16.58%). (2) The total score of the total psychological symptoms was 44.39 + 13.16, with a range of 29-110. The total positive rate of 13.82%. four factors was 1.75 + 0.63, anxiety 1.47 + 0.58, depression 1.51 + 0.58 and hostile 1.32 0.45, and the positive rate of psychological factors of three nationalities was between 8.00%-34.48%. P0.05, compared with the national norm, the somatization factors of the three ethnic groups were all higher than the norm, and the anxiety of the Bai Ku Yao was higher than the national norm and the enemy was lower than the norm. The antagonism factor of the Zhuang nationality was lower than the national norm. (3) the total coping style was 40.93 + 10.95, of which the positive should be 25.61 + 8.10, and the negative coping was 15.32 + 4.39. Han Han. Coping with the highest score, the second of Zhuang nationality, white pants Yao was the lowest. Three ethnic negative responses were higher than the national norm. (4) the total social support score was 27.72 + 6.07, the subjective support was 12.57 + 3.09, the objective support was 8.24 + 2.60, the support utilization was 6.91 + 2.42, and the subjective support of the Han nationality was higher than the Zhuang. Compared with the Zhuang normal model, three. The subjective support and social support utilization are less than the norm, and the objective support is higher than the norm. (5) the genotype and allele distribution of the 11 gene loci of the 5 genes of the screening, the allele G/A of the NPSRlrs12673132 site and the NPSR1rs6947841 allele C/T are statistically different among the sexes. Study significance (P0.05). Compared with the genotype and gene distribution of different nationalities, the alleles of HSP90BIrs17034977 and HSP90AA2rs2726836 are not statistically significant between the three ethnic groups except the genotype and allele of NPSRlrs324981 (P0.05), and the genotypes and loci of the other gene loci are between the three nationalities. The difference was statistically significant (P0.05). (6) the total score of the life events was more than 20, and the genotype and allele distribution of the positive / negative group were compared. The white pants Yao nationality, the Han population did not find the difference between the two groups; the COMTrs4680 genotypes of the Zhuang population; NPSRlrs324981 Genotypes and alleles, the genotypes of FKBP5rs1360780 were statistically significant in the two groups (P0.05). (7) the psychological symptom factor was more than 2 of the mental symptoms positive, and the genotype and allele distribution of the positive / negative group of the screening gene locus were compared, and the two groups of anxiety factors of the Bai pants Yao population were compared. There was significant difference in the distribution of genotypes and alleles between FKBP5rs1360780 and FKBP5rs3800373 (P0.05). In the Zhuang population, the genotype of COMTrs769224, NPSR1rs6947841 and NPSR1rs6972158 loci were statistically significant between the two groups of anxiety factors (P0.05); FKBP5rs1360780 alleles were among the two groups of depressive factors. The difference was statistically significant (P0.05). The HSP90AA2rs2726836 alleles of the Han population were statistically significant in the two groups of somatization factors (P0.05).NPSR1rs324981 alleles were statistically significant in the two groups of depressive factors (P0.05).COMTrs769224 genotypes and alleles, HSP90AA2rs2726836 alleles were in a statistical significance The differences between the two groups were statistically significant (P0.05). (8) the genotype and alleles of different coping styles were compared, and the distribution of NPSR1rs6972158 alleles in the Han nationality was statistically significant (P0.05). The subjective support of the screening gene loci of Bai Ku Yao nationality, Zhuang and Han nationality was analyzed by multivariate variance model. The difference between the three dimensions was not statistically significant (P0.05). (9) a single factor Logistic regression was used to analyze the risk of different genotypes and psychological stress (positive life events) in all the subjects, and the results were found to carry the TT genotype in the NPSRl based rs324981 locus AA genotype. The risk of psychological stress decreased by 0.445 (95%CI:0.234-0.844), and the difference was statistically significant (P0.05). (10) the results of multiple factor Logistic regression analysis showed that the three psychological symptoms of somatization, anxiety and depression increased the risk of psychological stress by 2.381 times (95%CI:1.554-3.649), 2.017 times (95%CI:1.148-3.544) and 1.845 times (95%C). I:1.053-3.230), the difference was statistically significant (P0.05). The risk of diastolic and systolic pressure was 0.981 times (95%CI:0.968-0.995) and 1.025 times (95%CI:1.003-1.048) respectively. The difference was statistically significant (P0.05). Conclusion (1) the positive rate of overall life events in the population of Guangxi Bai Ku Yao people was higher, causing psychological stress. The most exciting events are family events. (2) the positive rate of the overall psychological symptoms of the study is in the normal range, and the level of anxiety is different among the three ethnic groups; the somatization of the three ethnic groups and the anxiety of the Bai Ku Yao are higher than the national average, and the enemy pairs of the two ethnic minorities are lower than the average level. Three ethnic groups should be negative. The positive response was higher than the national level. The positive response of the Han people was the most common. The total social support score of the three ethnic groups, the subjective support and the social support utilization were lower than the average level of the Zhuang, and the objective support was higher. (3) NPSRlrs12673132, the genotype or allele of the rs6947841 gene locus had sex differences.COMTrs6267, rs769224, rs468. 0, NPSR1rs12673132, rs324981, rs6972158, and FKBP5rsl360780, there are ethnic differences in genotype or allele of rs3800373 gene loci. (4) screening selected FKBP5 rs1360780, rs3800373, C0MT rs4680.769224, NPSR1 rs324981, polymorphism distribution in different ethnic groups. Differences in psychological symptoms and coping styles. (5) the genotype of NPSR1rs324981 allele carrying T allele may be a protective genotype of psychological stress. Somatization, anxiety and depression and elevated systolic pressure are the risk factors for psychological stress; diastolic pressure is a protective cause of psychological stress. Prime.
