Multiplex Relationships and HIV: Implications for Networka[euro]Based Interventions

The number of network members and the roles they play can influence risk behaviors and consequently intervention strategies to reduce HIV transmission. We recruited 652 people who use drugs (PWUD) from socially disadvantaged neighborhoods in New York City (07/2006-06/2009). Interviewer-administered...

description The number of network members and the roles they play can influence risk behaviors and consequently intervention strategies to reduce HIV transmission. We recruited 652 people who use drugs (PWUD) from socially disadvantaged neighborhoods in New York City (07/2006-06/2009). Interviewer-administered surveys ascertained demographic, behavioral, and network data. We used logistic regression, stratified by exchange sex, to assess the relationship between HIV status and the number of network members with different roles, treated as independent and multiplex (i.e., drug + sex). Those with more multiplex risk ties were significantly more likely to be HIV positive, but only among those not reporting exchange sex (AOR = 3.2). Among those reporting exchange sex, men reporting recent male sex partners were more likely to report HIV positive status (AOR = 12.6). These data suggest that sex and drug relationships among PWUD are interrelated. Interventions that target multiplex rather than single-role relationships may be more effective in influencing behavior change.Original Abstract: El numero de personas en una red social y las funciones de cada persona en esa misma red pueden influir sus comportamientos de riesgo y en consecuencia las estrategias de intervencion para reducir la transmision del VIH. 652 personas que usan drogas fueron reclutadas de barrios socialmente desfavorecidos en New York City (07/2006-06/2009). Las encuestas recabaron caracteristicas demograficas, comportamientos de riesgo, e informacion sobre la red social. Regresion logistica (estratificada por genero) evaluo la asociacion entre el estatuto serologico de VIH y el numero de personas de la red social, con funciones diferentes tratadas como relaciones independiente y multiplex (i.e., drogas + sexos). Los que tienen mas "relaciones riesgos multiplex" presentan una mayor probabilidad de estar infectados con el VIH, pero solo entre los que no han participado en el intercambio de sexo (AOR = 3.2). Entre los que han participado en el intercambio de sexo, hombres que recientemente tuvieron relaciones sexuales con hombres presentaron mayor propensidad a estar infectados con el VIH (AOR = 12.6). Estos datos sugieren que las relaciones sexuales y drogas entre personas que usan drogas estan interrelacionados. Las intervenciones que se dirigen a relaciones multiplex en vez de relaciones de solo una funcion pueden ser mas adecuadas para influir cambios de comportamiento.
