目的在四川省凉山州地区静脉吸毒人群队列研究中,采用应答驱动抽样方法,从社区中招募研究对象调查社会人口学特征。方法利用结构式问卷调查研究对象的社会人口学特征和招募方式,比较通过种子和其他途径招募研究对象的社会人口学特征。结果在379名招募的静脉吸毒人群中,24人(6.3%)来自项目工作人员信息,46人(12.1%)来自吸毒伙伴,309人(81.5%)来自种子推荐。除民族构成外,种子介绍的与其他方式招募的研究对象在年龄、性别、职业、文化程度、年收入、婚姻和住房状况的比较上差异无统计学意义。结论采用应答驱动抽样方法从社区中招募静脉吸毒人员可行,但尚需进一步探讨其对参加者社会人口学和高危行为特征的影响。
Objective To investigate the socio-demographic characteristics of cohorts of intravenous drug users in Liangshan Prefecture of Sichuan Province by means of response-driven sampling and recruiting subjects from the community. Methods The socio-demographic characteristics and recruitment methods of the subjects were studied by structured questionnaires, and the socio-demographic characteristics of the subjects recruited through seeds and other means were compared. Results Of the 379 intravenous drug users recruited, 24 (6.3%) were from project staff, 46 (12.1%) were from drug abusers and 309 (81.5%) were from seeds. Except for ethnic composition, there was no significant difference in age, sex, occupation, educational level, annual income, marital status and housing between the introduction of seeds and those recruited by other ways. Conclusion It is feasible to use response-driven sampling to recruit intravenous drug users from the community. However, we need to further explore the impact on social demography and risk behaviors of participants.
