title: Changes in the Use of Contraception at First Intercourse: A Comparison of the National Survey of Family Growth 1995 and 2006-2010 Databases.
abstract: To determine trends in characteristics associated with contraceptive use at coitarche from 1995 to 2006-2010.
  
  
  
  The National Survey of Family Growth (NSFG) 1995 and 2006-2010 databases were used to abstract variables of interest. Generalized linear models (GLM) were applied to examine the association between the use of contraceptive methods at coitarche and variables abstracted for each database.
  
  
  
  Of the 9599 women from the 1995 database included in this study, 3885 (40%) used contraception at coitarche in comparison to 4860 (82%) out of 5931 women assessed in 2006-2010. For both time periods, Hispanic women were significantly less likely to use contraception at coitarche when compared to White women. In the 1995 database, only women from families with incomes >$50,000 were more likely to use contraception at coitarche, while women from families with income > $20,000 were more likely to use contraception at coitarche in 2006-2010. There were some differences noted in the association between age at coitarche and contraception use at coitarche, but in general, women who had a higher age at coitarche were more likely to use contraception. For both time periods, women were more likely to use contraception at coitarche if they used barrier methods as their first form of contraception or if they obtained their first contraceptive method from a spouse, partner, or friend.
  
  
  
  Our results suggest that access to contraception may be associated with use of a contraceptive method at coitarche. Innovative measures need to be investigated so that this young population has increased access to more reliable methods before their first sexual experience.
