Abstract
Fundamento: Los sistemas de información sociosanitaria que monitorizan el consumo de drogas no profundizan en el análisis de las características sociodemográficas y de los patrones de consumo, ni en los factores que condicionan los problemas de salud. Se describe la metodología de reclutamiento y las características de una cohorte de jóvenes consumidores de cocaína. Métodos: Cohorte prospectiva de 720 consumidores de cocaína que no consumen habitualmente heroína, captados en la comunidad, independientemente de los servicios asistenciales, mediante métodos de referencia en cadena en las áreas metropolitanas de Madrid, Barcelona y Sevilla. Cuestionario administrado por ordenador y parcialmente autoadministrado. Análisis estratificado por ciudad y por frecuencia de consumo de cocaína base. Resultados: En los últimos 12 meses el 58,8% había consumido cocaína entre 1 y 2 días por semana; el 91,9% habitualmente la había esnifado, un 5,3% fumado y sólo un 2,8% inyectado; el 6,1% la había utilizado la mitad de las veces o más en forma de base. Hubo policonsumo con cannabis (93,6%), éxtasis (73,2%) y anfetaminas (60,6%); un 4,0% se había inyectado alguna droga. Los que habían usado «crack» (22,1%) tenían un menor nivel educativo, un consumo de cocaína más intenso, mayor prevalencia de consumo de otras drogas, en especial opioides, y prevalencia de inyección mucho más alta. Conclusiones: El estudio confirma y completa el perfil sociodemográfico y de consumo ofrecido por los sistemas de información basados en servicios o las encuestas poblacionales, en especial que una gran parte de los consumidores jóvenes son esporádicos y que existen dos subpoblaciones muy diferenciadas según el consumo o no de cocaína base.
Background: Health information systems that monitor drug use do not perform in-depth analyses of sociodemographic characteristics and patterns of use, or of the factors that influence health problems. We describe the recruitment methodology and characteristics of a cohort of young cocaine users. Methods: A prospective cohort of 720 cocaine users who were not regular heroin users, recruited in the community independently of the health services by chain referral methods in the metropolitan areas of Madrid, Barcelona and Seville was studied. A computer-administered and partially self-administered questionnaire was used. A stratified analysis by city and by frequency of base cocaine use was performed. Results: In the previous 12 months, 58.8% had used cocaine 1-2 days/week; 91.9% sniffed it regularly, 5.3 smoked it, and only 2.8% injected it; 6.1% had used it at least half the time in the form of base cocaine. Polydrug use was observed with cannabis (93.6%), ecstasy (73.2%) and amphetamines (60.6%). Approximately 4.0% had injected at least one drug. Crack users (22.1%) had a lower educational level, more intensive cocaine use, a higher prevalence of other drug use, especially opioids, and a much higher prevalence of injection. Conclusions: This study confirms and completes the sociodemographic and drug profile provided by the information systems based on health services or population surveys. The results show that a large proportion of young cocaine users consume the drug sporadically and that two very different subpopulations exist, according to whether or not they use base cocaine.
