title: Sexual behavior and intention to engage in sexual behavior in junior secondary school students in Hong Kong.
abstract: OBJECTIVE
  The present study examined the prevalence, changes, and demographic as well as psychosocial correlates of sexual behavior and intention to engage in sexual behavior in early adolescents in Hong Kong, with sexual behavior indexed by sexual intercourse.
  
  
  METHODS
  Three waves of longitudinal data on sexual intercourse, intention to engage in sexual intercourse, family functioning, and positive youth development were collected from 28 secondary schools in Hong Kong.
  
  
  RESULTS
  There were significant influences of grade and gender on adolescent sexual behavior or intention to engage in sexual behavior. Significant main effects of immigration status on sexual behavior were also found. While no effect of family economic background was found, effect of family intactness existed for sexual behavior. Family functioning and positive youth development at Grade 7 were negatively associated with students' sexual behavior and intention to engage in sexual behavior at Grade 9.
  
  
  CONCLUSIONS
  Grade, gender, immigration status, and family intactness were related to sexual behavior and/or intention to engage in sexual behavior in junior secondary school students. Promoting positive youth development and family functioning could serve as protective factors to reduce sexual behavior and intention to engage in sexual behavior in Chinese early adolescents in Hong Kong.
