Abstract

We drew upon 15 years of data from 8,810 adolescent and young adult females in the National Longitudinal Study of Adolescent to Adult Health. Using 40 time-varying adverse life events measured across 4 Waves (ALE), we created an additive index score whereby higher scores indicated greater ALE experiences. We employed Cox proportional hazard models, including race- and income-stratified models, to estimate the effects of ALE scores on time to first unintended pregnancies, controlling for sociodemographic, health and reproductive covariates. Among all women, a one-unit increase in ALE scores was associated with an increased rate of unintended first pregnancy (adjusted Hazard Ratio 1.11, 95% Confidence Interval=1.04-1.17). In stratified models, higher ALE scores increased rates of unintended first pregnancies among African-American (aHR=1.12, CI=1.01-1.25), Asian (aHR 1.69, CI=1.26-2.26), and White women (aHR=1.12, CI=1.03-1.22) and women in the lowest ($0-$19,999; aHR=1.21, CI = 1.03-1.23) and highest (>$75,000; aHR=1.36, CI=1.12-1.66) income categories, but not among the other sociodemographic groups.
