Postpartum LARC and Short Inter-Pregnancy Interval

Contraception; ePub 2016 Aug 30; Harney, Dude, et al

Following a short inter-pregnancy interval (IPI), women who receive postpartum long-acting reversible contraception (LARC) are less likely to become pregnant, a recent study found. The large cohort included 3,548 women who delivered at University of Illinois Hospital from 2005 to 2010 and were discharged with a plan for interval LARC. Researchers found:

• 62% of women attended a postpartum visit (PPV), 36.5% received LARC, and 11.4% conceived after a short IPI.

• Women who were multiparous (OR, 0.77) or chose a temporary contraceptive bridge to LARC (OR, 0.74) were less likely to attend their PPV.

• Women who missed their PPV (OR, 0.06) or chose a bridge (OR, 0.66) were less likely to receive LARC.

• Women who did not receive LARC (OR, 4.8), were multiparous (OR, 1.69), or of teenaged years (OR, 2.12) were more likely to conceive after a short IPI.
