title: Comparison of problematic behaviours of 10th and 11th year Southern English adolescents in 1985 and 2005. Part 1: Trends in gender behaviour.
abstract: To compare the problematic behaviours of 1985 adolescent 10th and 11th year students with that of 2005 pupils, and to examine current drink, drug and sexual activity.
  
  
  METHODS
  Utilised a standardised questionnaire from 1985 and replicated the survey in broadly the same area in 2005. The study was self-administered and guaranteed anonymity for pupil and school, and was able to eliminate any bravado reporting. In 1985 it was not possible to inquire about sexual behaviour nor 'binge' drinking but this study was able to explore current respondents drink and sexual behaviour, utilising a linkage analysis to examine any drink-drug-sexual behaviour axis.
  
  
  RESULTS
  In 1985 males significantly smoked, truanted, fought, vandalised, stole and 'drugged' more than girls, but by 2005 females significantly smoked, drank, used cannabis more than boys. Current adolescent girls were more often were 'binge drinkers' (29%-15%) and sexually active than boys (23% to 11%). Amongst 10th year 8% of boys and 16% of girls were actively sexually, by the 11th year it was 15% of boys and 31% of girls.
  
  
  CONCLUSIONS
  Over the 20 years the traditional differences in troublesome youth behaviour has changed, with girls behaving similar or worse than boys, which along with Binge Drinking and greater sexual activity, puts them at greater risk, which is a challenge to parents and services, nonetheless, the majority of young people do Not engage in these problematic behaviours.
