A301Poster presentations separate needs. There is no Gender disaggregated data on IDUs available (UNODC 2004). Given that the socio-economic background and psychological conditions of FIDUs are different from their male counterparts (UNODC 2004), this study has been undertaken to study the sexual practises of and drug use pattern among FIDUs in Sikkim. Methods The study has been conducted among FIDUs registered under the government projects operational in Sikkim. The sample had been selected on the basis of stratified random sampling. Structured Questionnaires had been developed and the Interviewers had been oriented on the research tool. Results The study reveals that 73% of the FIDUs are sex workers, while 27% have multiple sexual partners. 36% inject drugs alone (70% have suffered overdose) while 64% inject drugs in groups. 80% of the respondents consume both injecting and non-injecting drugs. 39% are daily drug users and the rest weekly. 38% and 42% are using drugs since for last 6 months and over one year respectively, highlighting that drug use is an age old practise and there are continuous new entries. Although only 10% of the respondents use condoms, 89% use oral contraceptives thereby reducing chances of pregnancy but risk of STI and HIV remain. 57% of the respondents have suffered from STI. Conclusion Thus, the study reveals that convergence of drugs related services and sexual & reproductive health services are essential. Unsafe injecting drug use combined with unprotected sex with multiple partners needs to be recognised and addressed through a comprehensive programme. Background Men who have sex with men (MSM) in India are mostat-risk of HIV infection, with HIV prevalence almost 20 times higher than that in the general population. We describe the relationship between frequency of alcohol use and HIV-related risk behaviours among Indian MSM to develop strategies for addressing alcohol use within HIV interventions. Methods Data for this analysis were drawn from a cross-sectional bio-behavioural survey (2009)(2010) conducted in the states of Maharashtra, Tamil Nadu and Andhra Pradesh. 3,880 MSM were recruited from cruising sites using time-location cluster sampling. Binary logistic regression was carried out to assess relationships between frequent alcohol use and other sexual risk behaviours Results We categorised those who reported consuming alcohol daily or at least once a week as 'frequent' drinkers (40% of the sample) and the remaining as 'infrequent' drinkers. Among frequent drinkers, majority were above 24 years (66%), literate (85%), self-identified as Kothis[feminine and receptive partner] (53%), had paying male partners (65%) and were exposed to HIV prevention interventions (78%). Multivariate analysis showed that frequent alcohol drinkers were more likely to be above 24 years (adjusted odds ratio [AOR] 1.37, p < 0.05) and employed (AOR 1.54, p < 0.05). Frequent alcohol drinkers were less likely than infrequent drinkers to report consistent condom use with paying male partners (AOR 0.75, p <...
