AB BACKGROUND AND OBJECTIVES: Results of prospective cohort studies can be
biased when subjects selectively refuse to participate or be included in
follow-up. GOAL OF THIS STUDY: To assess the potential for bias in a
longitudinal study of sexual risk behavior among men who have sex with
men. STUDY DESIGN: This was a cross-sectional comparison of clinical
data regarding men who have sex with men attending an urban human
immunodeficiency virus testing clinic. RESULTS: Of 3,390 men who have
sex with men invited to participate, 2,063 refused, 589 dropped out
after completing an initial study questionnaire, and 738 participated in
follow-up at 6 months. There were no significant differences in the
same-gender sexual behaviors of participants, dropouts, and
nonparticipants, with one exception: Nonparticipants were more likely to
abstain from receptive oral sex (27%) compared with participants (18%)
or dropouts (21%). CONCLUSION: The similarities in reported activities
among participants, dropouts, and nonparticipants suggest that selection
bias may have limited impact on cohort studies of sexual behavior.
