【摘要】 目的了解2009年深圳市劳务工甲型肝炎的流行特征以及甲型肝炎病毒(hepatitis Avirus,HAV)IgG抗体水平。方法在深圳市44家工厂的4 088名劳务工中随机抽取1 003人的血样本,采用酶联免疫法(ELISA)检测抗-HAVIgG,采用SPSS 16.0软件分析处理数据。结果 1 003人中抗-HAVIgG阳性率为85.8%,抗体阳性率随着年龄的增加而升高;抗体阳性者平均年龄大于阴性者;抗体水平在男女之间、流水线工人和其他工种工人以及接种过甲肝疫苗与未接种过疫苗人群之间的差异无统计学意义;受教育程度越低、来深圳时间越长的工人,其抗体阳性率越高;来自海南、河北、云南、新疆、宁夏、江苏和吉林等省的劳务工人的抗体阳性率最高(100%);抗体阳性者家庭收入较阴性者低。结论深圳劳务工HAV感染率处于较高水平,抗体阳性率随年龄增加而升高,劳务工对免疫接种的认识贫乏,相关部门应该加强宣传指导,并建立持续完善的招工健康体检制度。更多还原

【Abstract】 Objective To know the epidemic features of hepatitis A and level of the IgG anti-HAV antibodies among immigrant workers in Shenzhen in 2009.Methods Sera were randomly collected from 1 003 people of 4 088 immigrant workers in 44 factories of Shenzhen.Enzyme-linked immunosorbent assay(ELISA) was used to detect anti-HAV IgG.The data was analyzed by software SPSS 16.0.Results Of 1 003 immigrant workers,85.8% were positive for IgG anti-HAV.The prevalence of anti-HAV IgG increased significantly with age.The average age of the antibody-positive was higher than the negative.There was no significant difference in the seroprevalence between male and female population,pipelining workers and other discipline workers,immunization and no vaccination group.The lower educational level and longer time of staying in Shenzhen,the higher of the antibody masculine gender rate.There was no significant difference among different regions in seroprevalence,the highest were Hainan,Hebei,Yunnan,Xinjiang,Ningxia,Jiangsu and Jilin.Family income of the antibody-positive group was lower than the negative.Conclusions The infection rate of HAV was at a high level in immigrant workers of Shenzhen.Positive rate of antibody increased with age significantly.Immigrant workers had poor understanding about immunization.The relevant departments should strengthen health education and set up continuous examination system of recruitment.更多还原
