Objetivo: identificar asociaciones entre las redes de amigos (densidad de la red de amigos, comportamiento de los amigos, popularidad y conglomerados de amigos), y los comportamientos relacionados con el consumo de alcohol en estudiantes universitarios. Métodos: estudio transversal de asociación. Se aplicaron mediciones sociodemográficas (sexo, edad, nivel socioeconómico, estructura familiar), consumo excesivo y riesgoso de alcohol, consumo de cigarrillo y variables de la red social. Mediante regresión logística se estiman OR e intervalos de confianza. Resultados: de las variables de la red social en mujeres, la densidad de la red se asoció al consumo riesgoso de alcohol, pertenecer al programa de Biología, al nivel socioeconómico alto y tener estructura familiar monoparental son factores que aumentan el consumo riesgoso de alcohol. En hombres aumentar la cantidad de amigos con consumo riesgoso de alcohol, tener estructura familiar monoparental y ser fumador, se asociaron al consumo riesgoso de alcohol. Respecto al consumo excesivo de alcohol en mujeres se encontró asociación con la cantidad de amigos con consumo excesivo de alcohol y pertenecer al programa de Biología. Conclusiones: el consumo riesgoso y excesivo de alcohol se asocia con la red social de amigos y es diferente por sexo. La red social de amigos universitarios es un medio en el que se comparten comportamientos no saludables, lo cual sugiere la importancia de indagar sobre el tema como un elemento que puede ayudar a combatir las enfermedades crónicas no transmisibles, esto ayudaría a definir perspectivas renovadas de promoción de la salud en universitarios.
Abstract. Objective: identify associations between networks of friends (density of the network of friends, behavior of friends, popularity and friend clusters), and alcohol-related behaviors in college students. Methods: cross-sectional association study. Sociodemographic measurements (sex, age, socioeconomic level, family structure), excessive and risky alcohol consumption, cigarette consumption and variables of the social network were applied. Using logistic regression, OR and confidence intervals are estimated. Results: of the variables of the social network in women, the density of the network was associated with risky alcohol consumption, belonging to the Biology program, high socioeconomic status and having a single-parent family structure are factors that use risky alcohol consumption. In men, the number of friends with risky alcohol consumption increases, having a single-parent family structure and being a smoker, were associated with risky alcohol consumption. Regarding excessive alcohol consumption in women, an association was found with the number of friends with excessive alcohol consumption and belonging to the Biology program. Conclusions: the risky and excessive consumption of alcohol is associated with the social network of friends and is different by sex. The social network of university friends is a means in which unhealthy behaviors are shared, which suggests the importance of investigating the subject as an element that can help combat chronic non-communicable diseases, this would help define renewed perspectives of promotion of health in university students.
