Note: Models adjusted for sex, socioeconomic status, race, exposure to benzene, height‐for‐age z scores, perinatal complications and maternal age, respiratory illness, or HIV. Bold values represent associations that reached a P‐value of <0.05. There were no results for the associations with postnatal PTSD exposure because of few observations.

Abbreviations: CI, confidence interval; IPV, intimate partner violence, PTSD, posttraumatic stress disorder. tPTEF/tE, ratio of time to peak tidal expiratory flow over total expiratory time.

^aAssumption of no departure from linear trend for postnatal PTSD because of small samples.
