Risk factors associated with tobacco, alcohol and drug use among adolescents attending secondary school in three cities from Argentina

Tobacco, alcohol and drug use starts at an early age. It is important to identify risk factors associated with initiation. In 2014, a survey was conducted among students attending first year of secondary schools in Buenos Aires, Córdoba, and Tucumán. A total of 3172 students completed the survey (42% were girls); their mean age was 12.8 years old. Findings showed that 10% had smoked; 32% had consumed alcohol; 17% had a heavy drinking episode in the past month; and 8% had used at least one illegal drug once in their lifetime. A high sensation seeking index was associated with the use of tobacco (odds ratio [OR]: 4.25, 95% confidence interval [CI]: 2.2-8.1), alcohol (OR: 5.56, 95% CI: 3.73-8.31), and marijuana, coca paste or cocaine, (OR: 11.73, 95% CI: 5.81-23.69). Having friends who smoke or drink was associated with tobacco (OR: 12.6, 95% CI: 7.8-20.5) and alcohol use (OR: 5.17, 95% CI: 4.15-6.40). Having permissive parents in terms of media use was associated with tobacco use (OR: 3.7, 95% CI: 2.1-6.5), and perceiving a low parental support and control (OR: 3.02, 95% CI: 1.40-6.52) was associated with marijuana, coca paste and cocaine use.El consumo de tabaco, alcohol y otras drogas comienza a temprana edad. Es importante identificar los factores de riesgo asociados al inicio. En 2014, se encuestaron estudiantes de primer año del secundario en Buenos Aires, Córdoba y Tucumán. Respondieron 3172 alumnos (42% de mujeres); edad media de 12,8 años. El 10% había fumado; el 32% había consumido alcohol; el 17% había tenido consumo excesivo durante el último mes, y 8% había consumido, al menos, una droga ilícita en su vida. El índice de búsqueda de emociones alto se asoció al consumo de tabaco (OR 4,25; IC 95%: 2,2-8,1), alcohol (OR 5,56; IC 95%: 3,73-8,31) y marihuana/paco/cocaína (OR 11,73; IC 95%: 5,81-23,69). Tener amigos que consumían tabaco/alcohol se asoció al consumo de tabaco (OR 12,6; IC 95%: 7,8-20,5) y alcohol (OR 5,17; IC 95%: 4,15-6,40). Tener padres que imponían pocas restricciones en el uso de medios se asoció al consumo de tabaco (OR 3,7; IC 95%: 2,1-6,5) y percibir un bajo control y soporte parental (OR 3,02; IC 95%: 1,40-6,52) se asoció al consumo de marihuana/paco/cocaína.
