【摘要】：目的评价“十二五”国家传染病重大科技专项项目中河南省艾滋病防治项目地区HIV筛查人群样本代表性和数据质量,以便准确估计HIV阳性率和HIV新发感染率;分析调查数据存在的主要问题及原因,为今后河南省流行病学现场调查工作提供参考依据。方法采用多阶段随机整群抽样方法,于2012年9月-2013年6月,在河南省上蔡、永城、确山、沈丘、济源5个项目县抽取居民2112766万人,对其进行问卷调查和健康体检,2014年10月-2015年3月期间,依据第一次健康体检的2112766万人的名单,对其进行第二次包含HIV检测的健康体检。采用样本代表性、数据完整性、准确性和录入及时性等四个指标评价数据质量。样本代表性从拟合优度检验和玛叶指数两个方面进行评价;完整性从人次缺失率、变量缺失率和二次体检符合率三个方面进行评价;准确性从重复率、逻辑错误率两个方面进行评价,最后运用综合指数法评价并比较五个地区调查数据质量。结果1代表性5个项目县调查样本和第六次人口普查户籍人口的年龄构成相同(2χ=8.202,P=0.879)。上蔡、永城、确山、沈丘的调查样本年龄构成与第六次人口普查户籍人口的年龄构成差异均无统计学意义(上蔡县:2χ=8.630,P=0.854;永城市:2χ=8.228,P=0.877;确山县:2χ=14.126,P=0.440;沈丘县:2χ=12.238,P=0.587)。选取10-69岁和20-79岁两个年龄组样本,计算得到调查样本总体玛叶指数为4.146,上蔡、永城、确山、沈丘、济源五个调查地区的玛叶指数分别为2.884、3.844、8.333、6.251、4.747,说明样本人口无年龄堆积现象。2完整性调查表整体完整率为82.356%,5个项目县人次缺失率分别为沈丘(10.324%)、济源(13.513%)确山(16.582%)、上蔡(19.495%)、永城(23.680%)。艾滋病专项档案整体完整率为87.462%,5个项目县人次缺失率分别为确山(8.364%)、济源(10.119%)、上蔡(12.809%)、沈丘(13.333%)、永城(20.269%)。二次体检符合率整体为85.793%,各个项目县二次体检符合率分别为确山(97.465%)、济源(84.545%)、上蔡(83.883%)、永城(83.824%)、沈丘(83.283%)。3准确性个人信息表和健康体检表的重复录入率分别为0.132%和0.637%,有AIDS既往史但HIV筛查结果显示“阴性”这类逻辑错误率为7.328%,依据身份证号推测的“性别”与自填的“性别”不一致率为0.209%,体检日期晚于录入日期这类逻辑错误率为1.171%。4及时性第一次与第二次健康体检日期与录入日期时间间隔分别为0-386天和0-388天,中位天数分别为0天和20天。5上蔡、济源、永城、确山、沈丘5个地区综合指数依次为2.914、3.507、4.319、7.964和10.919。结论(1)河南省艾滋病防治项目地区HIV筛查人群样本代表性达到了项目预期要求,未发现人为的选样偏性。调查数据完整性、准确性和录入及时性达到课题设计目标,但有待进一步提高。(2)五个地区调查数据质量从高到低依次为沈丘、确山、永城、济源、上蔡。
[Abstract]:Objective to evaluate the representativeness and data quality of HIV screening population in Henan Province in the 12th Five-Year Plan of the National Major Science and Technology Project on Infectious Diseases, so as to estimate accurately the positive rate of HIV and the new infection rate of HIV. This paper analyzes the main problems and causes of the investigation data, and provides a reference basis for the epidemiological field investigation in Henan Province in the future. Methods the multi-stage random cluster sampling method was used in Shangcai, Yongcheng, Henan Province from September 2012 to June 2013. In Queshan, Shen Qiu and Jiyuan five project counties, twenty-one billion one hundred and twenty-seven million six hundred and sixty thousand residents were selected for questionnaire survey and health checkup. During the period from October 2014 to March 2015, according to the list of twenty-one billion one hundred and twenty-seven million six hundred and sixty thousand people who underwent the first physical examination, A second health checkup involving HIV testing was performed. The sample was representative, and the data was complete. The data quality was evaluated by four indexes: accuracy and timeliness of input. The sample representativeness was evaluated from two aspects: goodness of fit test and Maye index. The absence rate of variables and the coincidence rate of secondary physical examination were evaluated from three aspects: accuracy, repetition rate, logic error rate, Finally, comprehensive index method was used to evaluate and compare the quality of survey data in five regions. Results (1) the age composition of census population in 5 representative counties and 6th censuses was the same. There was no significant difference between the age composition of Shen Qiu's survey sample and that of the household registration population in 6th censuses (Shangcai County: 2 蠂 ~ 2 / 8.630 / P ~ + 0.854; Yongcheng: 2 蠂 ~ (2) 8 ~ 2 ~ (28) P ~ + 0. 877; Cheshan County ~ (2) 蠂 ~ (2) 蠂 ~ (2) 蠂 ~ (1) ~ (14. 126) P ~ (0)) ~ (0.440); Shenqiu County: (2) 蠂 ~ (2) 蠂 ~ (2) (12. 238) (P ~ (0.587)). Two age groups, aged 10-69 and 20-79, were selected. The total Maye index of the survey sample was calculated to be 4.146, Shangcai, Yongcheng, Keshan, Shen Qiu, The Maye index of the five survey areas in Jiyuan is 2.884 ~ 3.844n 8.333n 6.251n 4.747 respectively, which shows that the overall integrity rate of the sample population without age accumulation phenomenon .2 is 82.3566.The missing rate of the five project counties is Shen Qiu (10.324D), Jiyuan (13.513)) Guoshan 16.582n, Shangcai (19.49555), Yongcheng (1949). The overall complete rate of AIDS special files is 87.462.The missing rate of the five project counties is respectively Keshan 8.364m, Jiyuan 10.119kung, Shangcai 12.809m, Shen Qihun 13.333Hu, Yongcheng 20.269b. The overall coincidence rate for the second medical examination is 85.793b, and the coincidence rate for each project county is Queshan respectively. The repeat input rates of accurate personal information form and health check-up form were 0.132% and 0.6377.The rates of repeated input of accurate personal information form and health check-up form were 0.132% and 0.6377.The results of AIDS screening showed "negative" logic error rate was 7.3288.The result of HIV screening was 7.328. The inconsistency rate of "sex" and self-filling "gender" was 0.209, and the logical error rate of medical examination later than the input date was 1.171.4 the interval between the first and second health check-up dates and the input dates were 0-386 days and 0-388 days, respectively. The median days were 0 days and 20 days, respectively. The five regional comprehensive indexes of Shangcai, Jiyuan, Yongcheng, Queshan and Shenqiu were 2.9140.507v 4.3197.964 and 10.91919.Conclusion 1) the representative population of HIV screening in Henan Province reached the expected requirements. The investigation data integrity, accuracy and inputting timeliness reach the design goal of the subject, but need to be further improved. The investigation data quality from high to low are Shen Qiu, Keshan, Yongcheng, Jiyuan. Shangchai.
