ABSTRACT
<p><b>OBJECTIVE</b>To explore the associated factors on loss to follow-up among men who have sex with men (MSM) in a prospective cohort study.</p><p><b>METHODS</b>We recruited eligible HIV-negative MSM at baseline in eight cities from June to October 2009. Interviewer-administrated questionnaire and blood testings for HIV, syphilis and human simplex virus type 2, were accomplished upon enrollment, 6-month and 12-month follow-up visits in the program. Loss to follow-up was recorded at each visit in this cohort. Univariate and multivariate statistical analysis were conducted to examine the associated factors on loss to follow-up.</p><p><b>RESULTS</b>A total of 3196 eligible MSM were enrolled at the baseline study. During one year of follow-up, 894 (28.0%) of them dropped out thoroughly while 2302 (72.1%) showed up at least on one visit. Factors as MSM who were at age 25 or younger, resided locally less than 1 year, being unemployed, self-recognized as heterosexuality or bisexuality, never taking HIV testing in the past year, having had sex with women in the past 6 months etc., were more likely to withdraw from the follow-up visits. Conclusion Age, length of residency, sex orientation and history of HIV testing were associated with the loss of follow-up among MSM cohort in our study. These factors should be considered in this kind of study design in the future.</p>
