上消化道出血與季節(jié)變化及氣象因素關(guān)系的研究
[Abstract]:Aim: to investigate the seasonal incidence of upper gastrointestinal hemorrhage (UGIB) in Jilin Province and its correlation with meteorological factors, so as to guide the patients to take preventive and health care measures as soon as possible in order to reduce the incidence rate and reduce the complications. Methods: the clinical data of UGIB inpatients diagnosed in the first Hospital of Jilin University from January 1, 2011 to December 31, 2012 were collected. The month and quarter of admission and the meteorological data of the same period were compared. The difference of the incidence of UGIB among quarters and the relationship between the meteorological factors and the incidence of UGIB were analyzed. Results: a total of 681 patients were enrolled in the study, including 509 males and 172 females, male: female 2.96 ml; There were 63 cases (9.25%) in the young group, 309 cases (45.37%) in the middle-aged group and 312 cases (45.81%) in the elderly group. The incidence of UGIB in spring, summer, autumn and winter was 141143201196 cases, the difference was statistically significant (x2, 25.11, P < 0.01). The incidence of bleeding in autumn and winter was significantly higher than that in spring, summer (58.30% vs 41.70%, P < 0.01), autumn was higher than that in spring and summer (29.52% vs 20.70%, 29.52% vs 21.0%, P < 0.01). The incidence rate in autumn was more than that in October, which was the highest in October. Spearman bivariate correlation analysis showed that the incidence of UGIB was most significantly associated with monthly mean atmospheric pressure (rho=0.738,P=0.000), followed by monthly mean air temperature (rho=-0.533,P=0.007). The third is the monthly average human comfort index (rho=-0.462,P=0.023), monthly mean wind speed (rho=-0.359,P=0.085), monthly mean relative humidity (rho=0.168,P=0.431) and daily mean temperature difference (rho=-0.005,). P < 0. 98) was not significantly associated with the onset of the disease. The monthly mean atmospheric pressure and monthly mean air temperature were applied to multivariate linear regression analysis. The results showed that only the monthly mean atmospheric pressure had an independent effect on the number of monthly cases of UGIB (P = 0.002), after adjusting the influence of monthly mean air temperature factors (P = 0.055), and that only the monthly mean atmospheric pressure had an independent effect on the number of cases per month (P = 0.002). The regression equation can be established as follows: monthly incidence of UGB in our hospital =-1211.401 0.349 脳 monthly mean air temperature 1.254 脳 monthly mean atmospheric pressure. Conclusion: (1) there is a significant seasonal difference in the incidence of UGIB in Jilin Province, the incidence of UGIB in autumn and winter is significantly higher than that in spring and summer. (2) the incidence of UGIB in Jilin Province is positively correlated with monthly mean atmospheric pressure, and negatively correlated with monthly mean air temperature. Through the multi-variable linear regression analysis, the prediction equation can be established to forecast the medical weather. (3) the comfort index and its classification of human body are closely related to the incidence of UGIB and are easy to understand, so it is suitable for popularizing science and preventing the occurrence of diseases.
