摘 要:目的 调查江苏省一般人群HCV抗体的阳性率分布,分析感染HCV的危险因素.方法 在江苏省3个地区的传染病防制示范区以乡镇和行政村为单位随机整群抽样,进行问卷调查和血清HCV抗体检测,利用SPSS软件分析抗体阳性率在不同人群中的分布差异,Cox模型拟合1:4配对的logistic回归分析HCV感染危险因素.结果 HCV感染情况在不同人群分布有差异,女性感染率(0.965%,95%CI:0.899%~1.035%)高于男性(0.572%,95%CI:0.517% ~ 0.632%);3个县人群感染率(分别为0.131%,95%CI:0.103% ~ 0.164%;0.316%,95%CI:0.268% ~ 0.370%;2.173%,95%CI:2.039% ~ 2.315%)的差异有统计学意义;50~ 59岁年龄组感染率最高(1.577%,95%CI:1.425%~ 1.740%),<30岁年龄组最低(0.161%,95%CI:0.125% ~ 0.204%);受教育程度越低感染率越高,其中流动人口感染率高.危险因素分析显示,感染率最低的地区多因素分析显示住院史(OR=3.049,95%CI:1.322~ 7.036)、输血史(OR=14.319,95%CI:2.318 ~ 88.459)和共用剃刀(OR=3.604,95%CI:1.096~ 11.851)是HCV感染的独有危险因素;感染率较低的地区分析显示仅血制品使用史(OR=7.202,95%CI:1.170~ 44.310)是独有危险因素;感染率最高的地区显示献血史(OR=7.496,95%CI:6.121~ 9.180)、输血史(OR=2.305,95%CI:1.578~ 3.369)和侵入性检查史(OR=1.258,95%CI:1.021 ~ 1.549)为独立危险因素.不同年龄组单因素分析显示,30~39岁组与他人共用剃刀是独有危险因素,50 ~ 59岁组有针灸史是该年龄组危险因素,50~59岁和60~ 69岁组有侵入性检查是危险因素.结论 HCV感染在中老年人、教育程度低、流动性强的人群中感染率高,不安全献(输)血、血制品使用可能是既往几十年中HCV感染的主要危险因素;针灸、侵入性检查以及共用剃刀等在不同人群中的危险度有差异.Objective To investigate the hepatitis C virus (HCV) infection rate among general population in Jiangsu province and to analyze the main risk factors for HCV infection.Methods Subjects in 3 counties were surveyed by stratified cluster random sampling in the National Major Science and Technology Projects demonstration area in Jiangsu province.Interview was carried out with uniformly-designed questionnaires.Blood samples were collected and anti-HCV tested.Data were analysed under SPSS 13.0.Case-control study was conducted on two groups with subjects under 1:4 matching by sex,age,village of residence and status of HCV infection.Cox' s proportional hazards regression analysis was then performed to analyze the risk factors for HCV infection.Results The positive rate of anti-HCV was higher in females (0.965%,95%CI:0.899%-1.035%) than in males (0.572%,95%CI:0.517%-0.632%).Significant differences were noticed among the positive rates of anti-HCV in the three counties (0.131%,95%CI:0.103%-0.164% ; 0.316%,95%CI:0.268%-0.370% ; 2.173%,95% CI:2.039%-2.315%,respectively).Peak prevalence of anti-HCV (1.577%,95%CI:1.425%-1.740%) was observed among persons at 50-59 years of age.Bottom rate (0.161%,95%CI:0.125%-0.204%) was observed below 30 years of age.High anti-HCV positive rate was detected in people with lower education background or belonged to ‘floating population’.Factors as having histories of hospitalization (OR=3.049,95% CI:1.322-7.036),blood transfusion (OR=14.319,95%CI:2.318-88.459) or sharing razor (OR=3.604,95%CI:1.096-11.851) were risk factors of HCV infection in the area with the lowest anti-HCV positive rate.In another county,factor as having histories of ‘blood products transfusion’ (OR=7.202,95% CI:1.170-44.310) appeared important while in the third county,having history of ‘blood donation’ (OR=7.496,95%CI:6.121-9.180) ; ‘blood transfusion’ (OR=2.305,95%CI:1.578-3.369) and ‘invasive physical examination’ (OR=
