LARC Placement Among Active Army Servicewomen

Obstet Gynecol; ePub 2017 Apr 4; Erickson, et al

Rates of long-acting reversible contraceptive (LARC) insertion are low but rising among active-duty US Army servicewomen, a recent study found. These rising rates are driven by increasing implant use, according to a retrospective cohort study which included 114,661 servicewomen aged 18 to 44 years from 2011 to 2014. Data were analyzed to assess rates and predictors of LARC initiation. Researchers found:

  • 14.5% of servicewomen received an LARC method; 60% received an IUD.
  • IUD insertions decreased over the study period, whereas LARC uptake increased, driven by an increase in implant insertions.
  • Younger age was a positive predictor of LARC uptake.
  • 26.2% of IUD users had 1 child compared with 13.2% among non-LARC users.
  • The majority of those initiating IUDs were married.
