Marijuana consumption among Colombian adolescents Background: Marijuana consumption is a public health problem. Aim: To determine the life time prevalence of marijuana use among Colombian adolescents and the factors associated with its consumption. Material and Methods: Secondary analysis of data from a study aimed to determine the prevalence of smoking. A self-administered and anonymous questionnaire was answered by 814 adolescents aged 14 ± 2 years (439 women). Results: Ten percent of respondents consumed marijuana at least once in their life. A logistic regression analysis showed that professing a non-christian religion, being smoker and having an age over 12 years, was associated with marijuana consumption. Conclusions: There is a high frequency of marijuana use among these adolescents.
Deliberate self-harm and psychoactive substance use in colombian school adolescentsBackground: Deliberate self-harm and the consumption of psychoactive substances are important public health problems among adolescents. Aim: To determine the association of deliberate self-harm with the consumption of psychoactive substances, in school adolescents in Colombia. Material and Methods: A survey about deliberate self harm and psychoactive substance use during the last 12 months was answered by 80 018 adolescents aged between 12 and 18 years. Results: The prevalence of deliberate self-harm in the last 12 months was 14.1%. The use of psychoactive drugs was associated with deliberate self-harm. The greatest association was observed with the use of non-prescription tranquilizers (Odds ratio 4.05 95% confidence intervals 3.42-4.81). Conclusions:We observed an association between deliberate self-harm and the consumption of different psychoactive substances.
Introducción: La marihuana es concebida como una droga de bajo riesgo, considerada ilegal en Colombia, si bien es la más consumida por los adolescentes. Objetivo: Describir la prevalencia y examinar los factores asociados al consumo de marihuana durante los últimos 30 días por adolescentes escolarizados de Colombia. Método: Estudio transversal analítico. Muestra constituida por 80.018 adolescentes escolarizados entre 12 y 18 años. Se considera “adolescente consumidor de marihuana”, a aquél que declaró haberla consumido durante los últimos treinta días. Se tuvieron en cuenta variables de interés, el sexo, la edad, el tipo de colegio, los episodios de ideación suicida y autolesión deliberada, la existencia de problemas de rendimiento académico y disciplinarios. Se realizó una descripción de la prevalencia de marihuana por cada una de las variables de interés. Se estimaron asociaciones por medio de modelos lineales generalizados, todos los análisis fueron ajustados por el factor de expansión. Resultados: La prevalencia de consumo de marihuana en los últimos 30 días fue del 4,3 % (IC 95 % 4,1 %- 4,6 %). Las mayores prevalencias de consumo se registraron en adolescentes que habían reportado 3 o más veces de ideación suicida en los últimos 12 meses, y en aquellos que acusaron 3 o más veces de autolesión deliberada en los últimos 12 meses (10,4 % y 10,0 %, respectivamente). Se encontró una asociación con todas las variables estudiadas. Conclusiones: Se evidenció una fuerte asociación entre el consumo de marihuana y presencia de episodios de autolesiones deliberadas y episodios de ideación suicida en adolescentes escolarizados.
