目的了解四川省出境劳务人员法定传染病的流行病学特征。方法描述2007-2011年间,四川省84 169人次出境劳务人员中乙肝、丙肝、HIV和梅毒4种传染病按人口学特征分层的检出率,采用χ2检验比较组间差异,采用趋势χ2检验分析检出率的时间趋势和年龄趋势。结果 HBsAg、HCV-Ab、HIV-Ab和梅毒抗体的检出率分别为7.77%、0.51%、0.05%、1.56%。HBsAg、HCV-Ab和梅毒抗体的检出率随年龄增长逐渐增高,男性多于女性。HBsAg检出率逐年上升(趋势χ2=6.202,P=0.013),HCV-Ab检出率逐年下降(趋势χ2=24.004,P<0.001)。结论青壮年男性是出境劳务人员传染病监测的重点人群,乙肝的输出风险仍较高,应重点对劳务输出人员开展针对乙肝的健康教育和疫苗免疫,并完善后续监管工作。
Objective To understand the epidemiological characteristics of the legal infectious diseases among service workers who leave the country in Sichuan Province. Method Description The detection rates of four infectious diseases of hepatitis B, hepatitis C, HIV and syphilis in Sichuan province during the period from 2007 to 2011 were divided by demographic characteristics. Chi-square test was used to compare the differences between the groups. The trend χ2 test Analyze the time trend and age trend of the detection rate. Results The detection rates of HBsAg, HCV-Ab, HIV-Ab and syphilis were 7.77%, 0.51%, 0.05% and 1.56%, respectively. The detection rate of HBsAg, HCV-Ab and syphilis antibodies gradually increased with age, more men than women. The detection rate of HBsAg increased year by year (trend χ2 = 6.202, P = 0.013), and the detection rate of HCV-Ab decreased year by year (trend χ2 = 24.004, P <0.001). Conclusions Young men are the key population for outpatient service infectious disease surveillance. The risk of hepatitis B output is still high. Health education and vaccination against hepatitis B should be focused on labor exporters, and the follow-up supervision should be improved.
