【摘要】 目的在静脉吸毒人群队列研究现场通过6个月随访核实参加者个人联系信息真实性以探讨参加者提供虚假联系信息对队列保持率的影响。方法自2003年5月至6月在四川省西昌市以社区为基础的HIV阴性静脉吸毒人群队列研究6个月随访中,通过现场工作人员和种子调查进入队列的333名参加者个人联系信息真实情况。结果本次随访研究对象按约定期限完成回访的占73.3%(244/333)。28.5%(95/333)的参加者在队列招募时提供虚假联系信息。提供虚假联系信息的参加者6个月回访率(44.2%)低于提供真实联系信息的参加者回访率(84.9%)。在多因素Logistic回归模型分析中,发现个人联系信息真实性(OR,6.99;95%CI4.05-12.07)和民族(OR,2.15;95%CI,1.24-3.75)对队列保持率有影响。结论需进一步研究静脉吸毒人群提供虚假个人联系信息的原因,分析其对队列保持率的影响。更多还原

Methods A six month follow-up was conducted to conform participants’ contact information by outreach group and seeds with designed forms among 333 participants recruited.SPSS (11.5) was used to analyze data. Results 73.3% of 333 participants finished 6 month visit on time. After checking contact information, 28.5% participants were found providing false contact information. After controlling for sociodemographic variables and other factors, providing validity contact information (OR, 6.99; 95% CI, 4.05-12.07) and nationality (OR,2.15;95% CI,1.24-3.75) was significantly associated with retention rate at 6 month visit.
