農(nóng)村自殺未遂結(jié)局及其相關(guān)因素的前瞻性隊列研究
[Abstract]:1 research background suicide is a global public health and social problem. Suicide poses great economic and mental burdens on society and families. The WHO 2012 global suicide report showed: (1) about 804000 people committed suicide and the suicide rate was 11.4/10 million; and the suicide rate of men and women was 15.0/10 million and 8.0/10, respectively. In most parts of the world, the rate of suicide is the highest in people over 70 years of age; (4) among the 15-29 years old, suicide is the second cause of death; (5) for the whole population, the incidence of attempted suicide is about 40 times the rate of suicide. In recent decades, the suicide rate has decreased significantly in all China and in Shandong Province, and the suicide mortality rate has been reduced. The ratio of village to city decreased, the suicide rate of men began to anti super women. The suicide rate "Shuangfeng" disappeared at the end of twentieth Century, but the suicide rate of the elderly was still higher and higher. The suicide is a complex behavior. The risk factors are mainly divided into character characteristics, individual and socioeconomic factors, psycho psychological factors, genetic factors and biology. It is estimated that the incidence of repeated suicide in attempted suicide is about 10%-30%. Attempted suicide is the most important risk factor for the future suicide attempt and again suicide. Many studies show that the repeated suicide population is characterized by mental disorders, relatively small age and more negative life events. It is shown that the use of violence in the first suicide is more prone to repeated suicides. The relationship between sex and repeated suicides is not uniform. More research is needed to prove the purpose of.2 Research (1) to evaluate the methods adopted in the suicide attempt and its control during the control follow-up. (2) from the basic economic demography and psycho psychological factors. The difference between the attempted suicide attempt and the normal control during the first visit and the follow-up. (3) to explore the changes in the important risk factors of suicide attempt (4) to estimate the incidence of repeated suicides in each follow-up period, and to explore the risk factors of the repeated suicide behavior, the.3 study method 3.1 subjects and the investigation process. From three counties (cities) of Tengzhou, Ningyang and Penglai, three counties (cities) were selected to collect data from all villages and towns of three counties from October 2009 to March 2011. The data of the case group were derived from the emergency department of the township hospitals and the county (city) hospitals. The center for Disease Control and prevention is responsible for collecting, examining and confirming cases. The initial visits are also from three counties (cities) above, randomly selected according to the principle of 1:1 pairing. The principle of matching includes similar age (not more than 3 years), sex, area, and suicide attempt. All residents at the time of first visit, including those who had attempted suicide, were compared with normal persons. In order to ensure follow-up, they interviewed him and interviewed myself in order to ensure the follow-up. The first follow-up was from October 2012 to December 2012. The second follow-up was from October 2016 to December 2016. First visit and follow-up are one to one, face-to-face way to conduct a questionnaire interview, conducted by a unified trainer in the order of the questionnaire. The survey site selects the township hospital, the village health room or the visiting family. When the informed consent is carried out, the interview object can be interviewed by the interview.3.2 interview tool. The interview tools were used as basic information questionnaire, standardized scale and diagnostic tool structure, including basic information questionnaire, suicide questionnaire, torsion scale, life event scale, psychological scale (including social support, self-esteem, anxiety and depression) and diagnostic tools for mental illness. The follow-up questionnaire added repeated suicide behavior. Questionnaire.3.3 statistical analysis used SPSS 16 to perform statistical description and analysis of.X2 test, t test or U test for the comparison of characteristics. Use the generalized estimation equation to analyze the change trend of attempted suicide risk factors and the risk factors of repeated suicides; the main results of the 4.1 reliability assessment interview information and psychology The status can reflect the real situation of the target people better. In addition, there is no difference between the age, sex and the first visit of the follow-up sample. The Cronbach's alpha coefficient of the dosage form is most above 0.7 and has better internal consistency. All of these reflect the information of the data obtained from the first visit and the information of the suicidal attempted group and the normal control group. The difference in demography was no longer obvious at the first follow-up and second follow-up. The incidence of negative life events, social support score, self-esteem score, depression score, anxiety score, and the prevalence of mental disorders in the two groups were still significantly different in the.4.3 suicide attempt. The incidence of negative life events in the attempted suicide group showed a downward trend (RR=0.1 65,95%CI:0.099-0.275) at the first follow-up (RR=0.1 65,95%CI:0.099-0.275), and a downward trend (RR=0.238,5%CI:0.142-0.399) at the time of follow-up (RR=0.238,5%CI:0.142-0.399), and there was a rising trend compared with the first follow up. The trend of the control group was not statistically significant. The prevalence of mental disorders in the attempted group decreased with time (first follow-up, RR=0.477,95%CI:0.293-0.778, second follow-up, RR=0.290,95%CI:0.181-0.463). For the normal control group, the overall trend also showed a downward trend, but there was no statistical significance. There was statistical significance (RR=8.742,95%CI:3.214-23.775), but there was no statistical significance in the second follow-up. Compared with the second follow-up, the trend of the first follow up score was also statistically significant (RR=12.705,95%CI:3.784-42.656). In addition, the trend of social support in the control group was not statistically significant. There was no statistical significance in the change trend of the self-respect score in the attempted group (P0.05). The reduction trend in the first follow-up was not statistically significant in the control group. The first time of the depression score in the attempted suicide group was statistically significant (P0.001) during the second follow-up. The trend of the depression score was not statistically significant in the control group. Compared with the first visit, the downward trend of the first follow-up anxiety score was statistically significant (RR=0.021,95%CI:0.003-0.128), but the trend of the change at the second follow-up was not statistically significant. Compared with the second follow-up, the decline trend of the first follow-up score was also statistically significant (RR=0.021,95%CI:0.003-0.133). The change trend in the control group was similar to that of the attempted suicide group. The related characteristics of.4.4 repeated suicide and the factors affecting the incidence of repeated suicides at the first follow-up were 1.57/100 years, and the density of repeated suicides was 1.41/100 years at the second follow up. The repetition rate of repeated suicide in the elderly was greater than that in the non elderly. The primary and secondary suicide characteristics of repeated suicides were compared and analyzed to find that the basic situation of the two was almost no difference from the characteristics of suicide. At the same time, the analysis of the mode of suicide could be obtained, and the first way of suicide was mainly to take pesticide (79%). But the proportion was small (36%), and the mode began to diversify, and more inclined to violent suicide (hanging, throwing, and wrists). Compared with single suicide, the repeated suicides were older, suffering from somatic disease, anxiety and mental disorders. In this study, 11 cases of repeated suicides included 7 cases of repeated suicide 1. 2 times, 3 cases of repeated suicide, 1 cases of repeated suicide 3 times. Age (RR=1.047,95%CI:1.007-1.088), anxiety (RR=1.050,95%CI:1.015-1.087) and mental disorder (RR=26.245,95%CI:3.170-217.305) as a risk factor for repeated suicides..5 study (1) in the case of unable to find myself, suicidal attempted follow-up can be used for information generation. (2) after the suicide, the mental state of the attempted suicide was significantly different from that of the normal control group, but the mental state of the attempted suicide was better than that of the suicide attempt. (3) the incidence of repeated suicide in rural areas was higher and the density of the elderly was larger. (4) the psychological and mental status of repeated suicides was significantly lower than those of suicide attempted suicide attempts. (5) the main risk factors for repeated suicide were mental disorder, high age and anxiety.
