Time-space sampling in minority communities: Results with young Latino menwho have sex with men

Objectives. This study addressed methodological issues influencing the feas ibility of time-space sampling in HIV prevention studies targeting hard-to- reach populations of minority young men who have sex with men (MSM). Methods. We conducted interviews with 400 men in 32 venues where young Lati no MSM congregate in New York City. Response rates and demographic and sexu al risk profiles are compared by venue type. Results. More than 90% of the men approached were screened. Among eligible men, participation rates exceeded 82%. Participation was higher at special events and gay venues compared with nongay venues (P < .05). Young MSM in n ongay venues were less likely to self-identify as gay (P < .01) or to repor t recent anal sex with a male (P < .10). Condom use did not vary by venue t ype but was lower with women than with men. If surveys had been limited to gay venues, about half of the young MSM surveyed in nongay venues would hav e been missed. Conclusions. Tune-space sampling of a relatively "hidden" minority young MS M population can be successful across a range of venues. However, the benef its of greater outreach must be weighed against the costs incurred recruiti ng participants in nongay venues.
