Purpose of the study. To evaluate the efficiency of the prevention programs aimed at the prevention of the spread of HIV infection, represent the it in disabled adjusted life years (DALY) and compare the efficiency with the prevention and treatment costs. Material and methods. Results of the panel study executed in 2006-2013 in 10 regions of Russian Federation in HIV infection risk groups (4 waves). The total number of include participants accounted of 9891. The study protocol included the detailed survey for the risk behavior and HIV testing. The obtained results of the study were used to calibrate the dynamic (Markov) model of the effect of the prevention on the length of the quality-adjusted life and treatment cost. The cost of the prevention was estimated on the base of reporting documents of prevention programs. Results. Programs of the comprehensive prevention of HIV-infection, among injecting drug users give rise in the significant decrease in the HIV incidence. The evaluation of the effect of prevention in frameworks of a multidimensional model shows odds ratio to be of 0.56 (95% CI = 0.40-0.78). This relative reduction of the incidence corresponds to the absolute incidence decrease from 3.98 per 100 person-years, among those not participating in prevention programs (95% CI: 3.37-4.69) to 2.22 per 100 person-years (95% CI: 1.89-2.62) among participants. This effect of the prevention leads to averting losses of 0.75-1.1 DALY per person, with most savings from the diminishing of the disability. In most plausible scenario this results in cost saving with return on the investment of 40 kopeks per rouble invested in prevention. Conclusion. Comprehensive programs of HIV prevention in Russian Federation possess of the significant effectiveness and under plausible assumptions are cost-saving. When discussing financing preventive measures they should be evaluated on real effectiveness and cost.
