Objective: Earthquakes are a terrible human disaster, the earthquake notonly caused huge casualties and property losses, will lead to experiencedpersons or families of the victims due to the fear, sadness and other hugepsychological damage arising from severe stress, leading to a variety of acuteand chronic stress response earthquake stress experienced serious impact onthe physical and mental health personnel, this study was designed forexperienced Tangshan earthquake follow-up part of the population, andsurvey experienced earthquake population change in blood glucose levels andthe incidence of diabetes mellitus, and to investigate the influence ofearthquake stress on long-term blood glucose and the incidence of diabetesmellitus, so as to provide a scientific basis for the prevention of diabetes.Methods: The study selected1,551Kai Luan Group workers who tookmedical examination from August2013to December2013at the Kai LuanGeneral Hospital health examination center in Tangshan city from healthydatabase of Kai Luan General Hospital, according to whether experienced the1976Tangshan earthquake is divided into two group, where people have notexperienced an earthquake as control group521cases, experienced Tangshanearthquake in1976, the population as a research group (exposed group)1030cases, when exposed groups according to whether their relatives died in theearthquake are divided into two subgroups: no death of a relative group521and have relatives died group509cases during the earthquake. Comparisonbetween the three groups of the general baseline data, analysis fasting glucosevalues between the three groups, the incidence of impaired fasting glucosetolerance and diabetes mellitus, while diabetes mellitus as the dependentvariable, gender, age, smoking, alcohol consumption, physical activity, bloodpressure, Waist, earthquake stress history, body mass index (BMI), family history of diabetes, triglyceride, total cholesterol, LDL, HDL, C-reactiveprotein as independent variables were analyzed with Logistic regressionanalysis. All data were entered into the computer when you lose dual entryform oracle10.2database, and then the data logic checks, DBF format fileexport program is formed by using SPSS13.0software package for statisticalanalysis. All normal measurement data as mean±standard deviation (x±s);three groups were compared using measurement data ANOVA, pairwisecomparisons using LSD test. According to CRP, TG was skewed distribution,used logarithmic transformation before analysis of variance between groups.Count data were analyzed by chi-square test, pairwise comparisons amonggroups by partition chi-squared of P values corrected. The related factors wereanalyzed by logistic regression. With P<0.05as significant difference, P <0.01was a very significant difference.Results:1No significant differences were found in age（F=2.046，P=0.130）, theaverage systolic blood pressure（F=1.575, P=0.207）, waist circumference（F=2.045, P=0.130）, BM（IF=1.092, P=0.336）among Tangshan earthquakestress experienced group of relatives died, no relatives died and normal controlgroup, Significant differences among three groups in gender（χ2=35.03, P=0.000）, education（χ2=36.27, P=0.000），family history of diabetes mellitus（χ2=8.422, P=0.015）, the average diastolic blood pressure（F=3.312,P=0.037）.2No Significant differences among three groups in smoking（χ2=0.078,P=0.962）, drinking（χ2=9.261, P=0.159）, physical exercise（χ2=4.399,P=0.355）.3Comparison of Biochemical index in three group, there were nosignificant differences on TG（F=1.952，P=0.142）, TC（F=2.050，P=0.129）,HDL-C（F=0.909，P=0.403）. Significant differences among three groups onLDL-C（F=5.065，P=0.006）, Pairwise comparison of earthquake stress of norelatives died group, relatives died group LDL were lower than in the controlgroup (P <0.01), others no significant difference. 4Compared with the control group，experienced earthquake stress norelatives died and relatives died group have elevated trends on fasting glucose,relatives died group of level fasting glucose were higher than no relatives diedgroup, but no significant difference.(P＞0.05).There was significant differences with the incidence of impaired fastingglucose among the three groups (χ2=6.301, P=0.043), experienced earthquakestress no relatives died and relatives died group had greater the incidence ofimpaired fasting glucose than the control group. The incidence of diabetesamong the three groups was significant difference (χ2=6.356, P=0.042),compared with the control group，experienced earthquake stress no relativesdied and relatives died group had higher the prevalence of diabetes mellitus，the incidence of diabetes mellitus is highest among the three groups.5According to gender Stratification, There was significant differenceswith the incidence of diabetes mellitus of women among the three groups (χ2=9.317, P=0.009), experienced earthquake stress group had higher theincidence of diabetes mellitus than the control group, relatives died group washigher no relatives died group. Compared the prevalence of diabetes mellitusof men among the three groups, no significant difference (P＞0.05).6Relatives died group were divided into three groups according to thenumber of relatives died, there was one people died, two people died, threepeople died or more. The incidence of diabetes among the three groupsgradually increased, but no significant difference (P＞0.05).7Results of logistic regression analysis：The factors influence on diabetesmellitus included age, gender, drinking, waist circumference, blood pressure,triglycerides, earthquake history of stress. The protective factor includedwomen (OR=2.231), occasionally drinking (OR=0.463). And the risk factorsincluded increasing age (OR=1.040), waist circumference thickening(OR=1.043), hypertension (OR=2.018) and a history of high triglycerides(OR=1.473), experienced earthquake stress no relatives died (OR=1.863),experienced the earthquake stress have relatives died (OR=2.304).Experienced the earthquake stress have relatives died was biggest risk factor for diabetes mellitus.Conclusion:1The study showed a high level fasting glucose among Tangshanearthquake affected population, and a higher prevalence of impaired fastingglucose diabetes mellitus in them, Tangshan earthquake as a source of stressand increased long-term incidence of impaired fasting glucose and diabetesmellitus.2After experienced the earthquake stress, prevalence of diabetes mellitushad increasing trend in women.3After adjusting for other risk factors the study showed, experienced theearthquake no relatives died were1.9times higher than the control group forthe risk of diabetes mellitus, experienced earthquake had relatives died were2.3times higher than the control group for the risk of diabetes mellitus,experienced the earthquake stress was an independent risk factor for diabetesmellitus.4Suffered the relatives died will increase the level of stress, the moresevere the degree of earthquake stress, the greater the risk of diabetes mellitus.5When psychological counseling and intervening to disaster areas ofpopulation, women as well as those experienced relatives death should begiven special attention and intervention, have an important role in theprevention of diabetes.
