The proportion of consistent condom use in the respondents was 49.9%. The proportion of receiving HIV counseling and testing, peer education, condom promotion and distribution was 54.4%, 27.1% and 28.6%, respectively. Multivariate analysis showed that higher educated（OR=0.67, 95% CI：0.50-0.90） and the longer interval from the last homosexual anal sex（OR=0.84,95%CI：0.72-0.97）ware protective factors for consistent condom use. Compared with the divorced or widowed, living with gay was risk factor for insistent condom use（OR=2.87,95% CI：1.11-7.47）.Conclusions The high risk behaviors among MSM in Yantai was popular,the rate of consistent condom use was low, the proportion of receiving AIDS intervention services need to be improved.
