title: [A survey on reproductive health related sexual behavior among middle school students in Luoyang city].
abstract: OBJECTIVE
  To explore the appropriate ways and contents of reproductive health education for middle school students and to understand reproductive health related sexual behavior and influencing factors among middle school students.
  
  
  METHODS
  Reproductive health related sexual behavior was evaluated among junior and senior middle school students in Luoyang by cluster sampling. The statistical software of SAS 8.1 was adopted for data analyses. Sexual behavior and influencing factors were analyzed by logistic regression.
  
  
  RESULTS
  Critical sexual behaviors were found significantly higher in senior students, including masturbation, sexual fantasy and sexual intercourse than that in junior students (P < 0.05), and boys had higher prevalence than girls (P < 0.05). Results from multivariate logistic regression model analyses indicated that incidence rate of sexual behavior among those who ever having had experiences was higher than those who were inexperienced (OR = 2.62, 95%CI: 1.21 - 5.66). Incidence rate of sexual behavior was related to access of reproductive health and STD/AIDS knowledge (OR = 3.09, 95%CI: 1.43 - 6.51). In addition, incidence rate of sexual behavior was related to attitude and relation of amour between boys and girls (OR = 2.24, 95%CI: 1.32 - 3.75).
  
  
  CONCLUSIONS
  Awareness on reproductive health knowledge among middle school students was not enough. Marginal sexual behaviors as masturbation and sexual fantasy had not been correctly and openly discussed to avoid inappropriate sexual activities.
