Abstract:

Objective To explore the main risk factors related to the incidence of Japanese encephalitis (JE), and to provide evidence for the prevention and control of JE.Methods We collected the data about case information by searching PubMed, China National Knowledge Infrastructure (CNKI), China Biology Medicine Disc (CBM), Wanfang Database, and database for Chinese Technical Periodicals (VIP) from 1995 to 2015, and we applied Stata 12.0 software for the Meta-analysis. Results Totally 7 case-control studies were selected (including 412 cases and 763 controls).The results of Meta-analysis showed that the factors of raising swines, house location, immunization history, and using screen windows were influential factors, and the OR value (95%CI) were 2.87(2.01-4.10), 2.46(1.55-3.89), 0.12(0.04-0.37), and 0.37(0.17-0.83), respectively. Conclusion Raising swines and living in the peripheral villages were risk factors of JE, and JE vaccination and using screen windows were protective factors.
