title: Recency of immigration, substance use, and sexual behavior among Massachusetts adolescents.
abstract: OBJECTIVE
  This study examined the relationships between recency of immigration, substance use, and sexual behavior.
  
  
  METHODS
  Surveys were conducted with 2635 Massachusetts 8th and 10th graders that allowed comparisons of health behaviors and risk and protective factors among students living in the United States "always," more than 6 years, or 6 years or less.
  
  
  RESULTS
  Compared with lifetime residents, immigrant youths (particularly those living in the United States 6 years or less) reported lower lifetime and recent alcohol and marijuana use (P < .001); sexual intercourse rates were similar across groups. However, recent immigrants were most likely to report peer pressures to engage in, and less parental support to avoid, risk behaviors (P < .001).
  
  
  CONCLUSIONS
  A window of opportunity exists to provide primary prevention programs in schools to immigrant youths that may reduce adolescent health risk behaviors.
