Risk factors for clonorchiasis: a Meta-analysis / 中国热带医学

ABSTRACT

@#Abstract Objective　Quantitative assessment of risk factors of clonorchiasis can provide prevention for clonorchiasis. Methods　Articles were retrieved in Chinese and English electronic databases from January 1, 2000 to December 31, 2020, including Wanfang Data, CNKI, PubMed, Web of Science, Embase. All studies were screened based on inclusion and exclusion criteria, and the quality of all enrolled literatures was evaluated. The software RevMan version 5.3 was used for Meta-analysis. The heterogeneity, sensitivity and publication bias of all included studies were analyzed. Results　A total of 95 articles were retrieved, and 6 were included in this Meta-analysis which were case-control studies. There were 5 articles in Chinese and 1 in English. There was no single literature with a large impact on the results, and the results of this study were relatively stable. There were 1 170 cases of clonorchiasis in total and 1 291 cases in control. Most of the cases were from hospital patients and community residents, and the floating population was small. Meta-analysis showed that there were three independent risk factors raw or semi-raw fish, raw or semi-raw shrimp, mix raw and cooked cutting boards, with a combined OR (95%CI) of 2.32(1.86, 2.88), 3.99(2.42, 6.58), 2.18(1.51, 3.14), respectively, with low heterogeneity consistent with the results of the total sample study I2 values for risk factors were 30%, 12%, 27%, respectively. The results of bias tests showed no publication bias (P=0.731, 0.725, 0.334, P>0.05). Conclusions　The key risk factors of clonorchiasis are raw or semi-raw fish, raw or semi-raw shrimp, mix raw and cooked cutting boards. Guidance and health education should be strengthened. It is necessary to strengthen the surveillance of clonorchiasis in the floating population, such as traveler, businessman and student.
