ABSTRACT
The Services of Prevention and Early diagnosis of HIV in Madrid (Spain) are set in selected primary care centers. Cultural mediators targeted to vulnerable groups (economic immigrants, MSM, sex workers ) perform risk assessment and counselling. Between 2010 and 2014 they performed 6 039 rapid-HIV test, 27.8 % in MSM, 41.2 % in men who have sex exclusively with women (MSW) and 31.0 % in women; 35.7 % in immigrants, mainly from Latin America. A reactive result was more common among MSM (6.0 %) compared to women (0.6 %) and MSW (0.5 %). In MSM it was associated to being immigrant and to antecedents of sexually transmitted infections (STI). Among MSW the factors associated to a reactive result were: seropositivity of sexual partner and heroine consumption, and in women: infrequent use of condoms, seropositivity of sexual partner and antecedents of STI. Preventive interventions to reduce risk of HIV transmission and for early detection should be adapted and targeted to high risk population.
