Condom Use & Incident STI After LARC Initiation

Am J Obstet Gynecol; ePub 2017 Sep 15; Mcnicholas, et al

Long-acting reversible contraceptive (LARC) users reported lower rates of consistent condom use and were more likely than non-long acting reversible contraceptive users to acquire a sexually transmitted infection (STI) in the 12 months following LARC initiation, a recent study found. The secondary analysis of the Contraceptive CHOICE Project compared changes in condom use and incidence of STI acquisition among new initiators of LARC to those initiating non-long acting reversible contraceptive methods. The study included 2 sample populations of 12-month continuous contraceptive users. The first included users with complete condom data (baseline, 3, 6, and 12 months) (LARC users: n=2,371; other methods: n=575). The second included users with 12-month STI data (LARC users: n=2,102; other methods: n=592). Researchers found:

  • Few participants in either group reported consistent condom use across all time points.
  • There was no difference in change of condom use at 3, 6, and 12 months compared to baseline condom use regardless of method type.
  • There were 94 incident STIs; with LARC users accounting for a higher proportion (3.9% vs 2.0%).
  • Initiation of a LARC contraceptive method was associated with increased STI incidence (OR, 2.0).
