Sexual behavior and drug use impact in gay, bisexual, and other men who have sex with men.

BACKGROUND: The emergence of chemsex has raised several concerns about gay, bisexual, and other men who have sex with men's (GBMSM) health. In this study we aim to analyze illicit drugs and chemsex use, sexual behavior and sexually transmitted infections (STI) in GBMSM who attended to a sexual health clinic and to explore any potential association between drug use and STI. METHODS: We conducted an observational study between January and June 2019 among GBMSM population attending to a STI clinic in Barcelona, Spain. An anonymous self-administered questionnaire was given consecutively to all participants older than 18 years who accepted to participate. RESULTS: A total of 514 GBMSM (median age of 34 years-old) were included. The median number of sexual partners in the last year was 20. Seventy-one percent did not use condoms consistently for receptive anal intercourse. Drug abuse prevalence in the preceding year was 64.2%, and 26.5% of the individuals practiced chemsex. Gamma-hydroxibutyrate/gammabutyrolactone, poppers and methamphetamine were the most common drugs in chemsex. Chemsex was associated to group sex (OR 9.8 [95 CI: 4-24]), HIV infection (OR 2.5 [95 CI: 1.1-5.8]), taking pre-exposure prophylaxis (OR 3.2 [95 CI: 1.5-7.1]), developing gonorrhea (OR 3.7 [95 CI: 1.5-8.8]) or syphilis (OR 6.7 [95 CI: 2.4-18.7]). CONCLUSIONS: The prevalence of drug use and chemsex was high among GBMSM in Barcelona. Chemsex was associated with group sex, taking PrEP, and contracting syphilis, gonorrhea, and HIV.

Antecedentes: El chemsex genera preocupaciones sobre la salud de gays, bisexuales y otros hombres que tienen sexo con hombres (GBHSH). En este estudio analizamos el uso de sustancias recreativas, chemsex, comportamiento sexual e infecciones de transmisión sexual (ITS) en GBHSH y exploramos cualquier asociación potencial entre el uso de drogas e ITS.MétodosEstudio observacional entre enero y junio de 2019 entre GBHSH atendidos en una clínica de ITS de Barcelona, España. Se entregó un cuestionario autoadministrado anónimo de forma consecutiva a todos los adultos que aceptaron participar.ResultadosSe incluyeron 514 GBHSH (edad mediana 34 años). La mediana del número de parejas sexuales en el último año fue de 20. El 71% no usó preservativo de manera consistente para el coito anal receptivo. La prevalencia de uso de drogas el año previo fue del 64,2% y el 26,5% de las personas practicó chemsex. Gamma-hidroxibutirato/gammabutirolactona, poppers y metanfetamina fueron las drogas más comunes en chemsex. El chemsex estuvo asociado a practicar sexo en grupo (OR 9,8 [IC 95%: 4-24]), infección por VIH (OR 2,5 [IC 95% 1,1-5,8]), profilaxis preexposición de VIH (PrEP) (OR 3,2 [IC 95% 1,5-7,1]), gonorrea (OR 3,7 [IC 95%: 1,5-8,8]) y sífilis (OR 6,7 [IC 95%: 2,4 - 18,7]).ConclusionesLa prevalencia de consumo de drogas y chemsex fue alta entre GBHSH en Barcelona. El chemsex se asoció con sexo en grupo, toma de PrEP e infección por sífilis, gonorrea y VIH. (AU)
