1994年对云南省瑞丽等地HIV感染者定群研究及KAP调查

１９９４年对已建立两年的吸毒者ＨＩＶ感染定群研究现场──云南省德宏州瑞丽市、陇川县及潞西县再次进行追踪调查，共调查吸毒者５２２名，全部采集了血样，其中１９９２年和１９９３年进入定群研究的静注毒品ＨＩＶ阴性者分别为２６名及３９名，检测结果１０名血清转呈阳性。瑞丽市、陇川县及潞西县静注者血清阳转率（／百观察人年）分别为２５．０％、１６．３％及０．０％。１９９４年新进入定群研究的静注者中有１０５名采集到血样，发现ＩＩＩＶ阳性４６名。瑞丽、陇川及潞西的ＨＩＶ感染率分别为６１．８％、３８．５％及０．０％。本次对５２２名吸毒者进行ＫＡＰ调查结果显示，民族、职业、文化程度与ＨＩＶ感染率之间有非常显著性差异（Ｐ＜０．０１）。潞西县ＨＩＶ阳性率低，可能与以汉族为主、文化程度高、很少去缅甸有关。

The result of KAP investigation from 522 drug users hasshown that there is a marked difference of the rate of HIV infections in the nationalities, occupations, educa-tion (P<0. 01).The main reason contributing the low rate of HIV infections in Luxi county is that the IVDUmainly are the Han nationality with higher education level, as well as travelling less to Burma.
