title: Lifetime use of illicit drugs and associated factors among Brazilian schoolchildren, National Adolescent School-based Health Survey (PeNSE 2012).
abstract: OBJECTIVE
  This study aimed at describing the prevalence of illicit drug use among 9th grade students in the morning period of public and private schools in Brazil, and assessing associated factors.
  
  
  METHODS
  The Brazilian survey PeNSE (National Adolescent School-based Health Survey) 2012 evaluated a representative sample of 9th grade students in the morning period, in Brazil and its five regions. The use of illicit drugs at least once in life was assessed for the most commonly used drugs, such as marijuana, cocaine, crack, solvent-based glue, general ether-based inhalants, ecstasy and oxy. Data were subjected to descriptive analysis, and Pearson's χ² test and logistic regression was used in the multivariate analysis.
  
  
  RESULTS
  The use of illicit drugs at least once in life was reported by 7.3% (95%CI 5.3 - 9.4) of the respondents. Logistic regression was used for multivariate analysis and the evidences suggest that illicit drug use is associated to social conditions of greater consumption power, the use of alcohol and tobacco, behaviors related to socialization, such as having friends or sexual activity, and also the perception of loneliness, loose contact between school and parents and experiences of abuse in the family environment. The outcome was inversely associated with close contact with parents and parental supervision.
  
  
  CONCLUSIONS
  In addition to the association with the processes of socialization and consumption, the influence of family and school is expressed in a particularly protective manner in different records of direct supervision and care.
