}KEY FINDINGS
Data from the National Vital Statistics System •Nearly 29.0% of U.S. mothers who had a second or higher-order birth in 2014 had a short interpregnancy interval of less than 18 months. •Short intervals (i.e., less than 6 months, 6-11 months, and 12-17 months) were more common for mothers aged 35 and over (5.7%, 16.3%, and 22.1%, respectively) than mothers who were under age 20 at their previous birth (5.1%, 8.8%, and 8.4%). •Short intervals of less than 6 months and 6-11 months were…

Rates of less than optimal IPI were high in this population already experiencing significant maternal-child health disparities, with short IPI a particular risk factor for poor outcomes for the most disadvantaged women, suggesting yet another precursor for adverse birth outcomes in those already most at risk.
Interpregnancy intervals and women’s knowledge of the ideal timing between birth and conception

Younger age and non-use of LARC are significantly associated with IPI <12 months and a minority of women with a short IPI perceived it to be ideal, suggesting prevention of short IPIs could be achieved with improved access to postnatal contraception.

An interval of 12–23 months is associated with the lowest risk of starting the second pregnancy with a higher body weight accounting for age, and birth spacing may merit exploration as a factor impacting on perinatal morbidity in countries with high prevalence of maternal obesity.

Dedicated maternal counseling during pediatric WCVs is an opportunity to influence behavioral change in women at risk of becoming pregnant as direct provision of MVIs increases the odds that women will report taking them at a higher rate than provider advice or no counseling at all.

Unlike overall infant mortality, injury-related infant mortality decreased with IPI length, suggesting that the timing between births may be a marker of risk for fatal infant injuries.
