title: Sexual knowledge, attitudes and practices of female undergraduate students in Wuhan, China: the only-child versus students with siblings.
abstract: OBJECTIVE
  This study explored sexual knowledge, attitudes and practices of female only-child undergraduates and made a comparison with students with siblings.
  
  
  METHODS
  Anonymously completed questionnaires were received from 4,769 female undergraduates, recruited using randomized cluster sampling by type of university and students' major and grade. Multivariate logistic regression was used to assess the effects of only-child on sexual knowledge, attitudes and practices among female undergraduates.
  
  
  RESULTS
  Of 4,769 female undergraduate students, 41.0% were only-child and 59.0% were students with siblings. Compared with students with siblings, only-child students scored higher on sex-related knowledge, were more inclined to agree with premarital sex, multiple sex partners, one-night stands, extramarital lovers and homosexuality, and were more likely to have a boyfriend and experience sexual intercourse (73.6% vs. 61.4%; 24.0% vs. 14.0%). Only-children were less likely to experience coercion at first sex and have first sexual intercourse with men not their "boyfriends" than children with siblings (3.3% vs. 6.4%; 20.7% vs. 28.8%). There were no significant differences on other risky sexual behaviors (e.g. multiple sex partners and inconsistent condom use) between the only-child students and students with siblings.
  
  
  CONCLUSIONS
  Sexual knowledge, attitudes and some practices of only-child female undergraduates were different from students with siblings. Intervention should be designed according to different requirements of only-children and non-only-children.
