• Introduction Secondhand smoke (SHS) exposure has been associated with increased sleep disturbance but not sleep duration among children with asthma, and among adolescents a greater frequency of restless sleep and decreased sleep duration. Prior studies, however, did not examine whether SHS exposure during childhood was associated with longitudinal sleep health. This study investigated both the cross-sectional and longitudinal associations between childhood SHS exposure and sleep duration and disturbance during childhood and middle adolescence. Methods Survey data from the age 9 and 15 waves (n=2869) of the Fragile Families and Child Wellbeing Study, a longitudinal birth cohort from 20 US cities, were analyzed. At age 9, parents reported whether their child was exposed to SHS, the child’s average amount of weekday sleep duration (hours), and whether the child had trouble sleeping. At age 15, teens self-reported habitual school-day time in bed (hours) and the number of nights they typically had problems falling or staying asleep. We tested for associations between age 9 SHS exposure and sleep duration and disturbance at ages 9 and 15 using regression analyses. Analyses adjusted for the child’s sex, age, race, childhood diagnosis of asthma, and baseline measures of family structure, household income, and mother’s education level. Results Exposure to SHS (11.9%) was associated with approximately 15 minutes shorter weekday sleep duration at age 9 (b=-0.262, p<0.001), but was not longitudinally associated with shorter habitual time in bed at age 15. Exposure to SHS was also associated with more nights experiencing trouble falling asleep at age 15 (b=0.269, p=0.022), but was not associated with trouble sleeping at age 9 or trouble staying asleep at age 15. Conclusion Our findings indicate that childhood SHS exposure is associated cross-sectionally with shorter sleep duration in childhood and longitudinally with trouble falling asleep (even after adjustment for age 9 sleep disturbance and diagnosis of asthma). Future research should investigate potential longitudinal effects of SHS exposure on sleep health. Support (If Any) R01HD073352
