Objective To investigate the influencing factors of follow-up of HIV seropositive cohort cohorts in intravenous drug users in Xichang City. Methods In May 2003, on a community-based cohort of intravenous drug users, semi-structured interview questionnaires were used to investigate the half-year cohort follow-up and the follow-up by appointment and its influencing factors. One-on-one interviews were conducted by trained interviewers in an independent interview room, and the contents of the open-ended questions were collated immediately after the interview. Results 45.5% (27/60) of the follow-up visits were completed on the agreed date. Qualitative interviews revealed that the reasons for the follow-up of the affected dates were as follows: Forgetting or misplacing the appointment date, compulsory detoxification by the public security department or family member could not be obtained Follow-up information, family support for research projects. Multivariate Logistic regression analysis showed that family support for the study (OR, 409; 95% CI: 136- 123, P <0.05) was a factor influencing follow-up dates. Conclusion Family support may be one of the reasons for the follow-up of cohorts of intravenous drug addicts. It is still necessary to study the completion of follow-up at different stages through the entire cohort and further study the factors influencing cohort follow-up.
