title: Use of the intrauterine device among adolescent and young adult women in the United States from 2002 to 2010.
abstract: OBJECTIVE
  Long-acting contraceptives, such as the intrauterine device (IUD), show potential for decreasing the incidence of unintended pregnancy. However, use among adolescent and young adult women remains low. We determined factors associated with IUD use among young women.
  
  
  METHODS
  We conducted an analysis of nationally representative, cross-sectional data from the 2002 and 2006-2010 National Surveys of Family Growth. We included sexually active women 15-24 years old. We used bivariate analysis to compare proportions of ever-use of any type of IUD in 2002 and in 2006-2010 and multivariable logistic regression to identify correlates of ever-use in 2006-2010.
  
  
  RESULTS
  We found an increase in IUD use in teens 15-19 years old, from .2% to 2.5% (p < .001), and among women 20-24 years old, 2.0% to 5.4% (p < .001). Use increased among nearly all subgroups of respondents. Compared with nulliparous young women, those with one prior delivery and with two or more deliveries were substantially more likely to have used an IUD (adjusted OR 11.43, 95% CI 3.61-36.16, and adjusted OR 13.60, 95% CI 4-46.48, respectively). Young black women were less likely to report IUD use (adjusted OR .32, 95% CI .16-.66), and women whose mothers received at least a high school education were more likely to report use (adjusted OR 2.56, 95% CI 1.22-5.43).
  
  
  CONCLUSIONS
  IUD use is increasing among adolescent and young adult women overall and among almost all sociodemographic subgroups. Nonetheless, use remains low, and nulliparous young women are highly unlikely to use the IUD.
