title: [Effects of TeenSTAR, an abstinence only sexual education program, on adolescent sexual behavior].
abstract: BACKGROUND
  Urgent measures are required to stop the increase in the frequency of pregnancies and sexually transmitted diseases among teenagers. A means of facing this problem is promoting sexual abstinence among youngsters. There are studies that confirm the efficacy of this approach.
  
  
  OBJECTIVE
  To show the results of the application of a holistic sexuality program (TeenSTAR) among Chilean teenagers.
  
  
  METHODS
  Students attending basic or high school were divided into a control or study group. The control group (342 students) received the usual education on sexuality given by their schools and the study group (398 students) participated in twelve TeenSTAR sessions lasting 1.5 hours each, given by a trained professor. Assessment of achievements was made using an anonymous questionnaire answered at the start and end of the program.
  
  
  RESULTS
  The rates of sexual initiation among control and study groups were 15 and 6.5%, respectively. Among sexually active students, 20% of those in the study group and 9% of those in the control group discontinued sexual activity.
  
  
  CONCLUSIONS
  A higher proportion of students in the TeenSTAR program retarded their sexual initiation or discontinued sexual activity and found more reasons to maintain sexual abstinence than control students.
