Data come from the population-based French birth ELFE cohort launched in 2011. P-IPV was assessed before and during pregnancy, at 2 months and 2 years post-partum. Children's sleep patterns were measured at 2, 3, and 5 years of age. Group-based trajectory modelling was used to identify trajectories of P-IPV and each child's sleep patterns. Associations between P-IPV and children's sleep trajectories were assessed by weighted multivariate logistic regressions. Five P-IPV trajectories were identified: minimal (64%), prenatal (14%), decreasing (9%), increasing (8%), and persistent (5%). Two trajectories of SOD (few 65% and many 35%), three trajectories of NA (few 49%, decreasing 24%, and many 23%), and three trajectories of NSD (short 21%, medium 56%, and long 23%) were identified. About 9513, 9512, and 9499 children were included in comparative analyses, respectively, focused on SOD, NA, and NSD. Increasing and persistent P-IPV trajectories were both associated with the trajectory of many SODs [odds ratio (OR) = 1.53, 95% confident interval (CI) = 1.24-1.91; and OR = 1.71, 95% CI = 1.31-2.22, respectively] and the trajectory of many NA (OR = 1.66, 95% CI = 1.29-2.13); and (OR = 1.95, 95% CI = 1.42-2.69, respectively). Associations between persistent P-IPV and decreasing and many NA were significant among girls (OR = 1.76, 95% CI = 1.12-2.75 and OR = 2.27, 95% CI = 1.39-3.71, respectively), but not among boys. Family interventions in response to IPV should pay particular attention to sleep patterns of children exposed to IPV.European journal of public healthIntimate partner psychological violence and children's sleep difficulties up to 5 years of age: an ELFE birth cohort.PMC12529263EN-2023CINT12El-Khoury FMelchior MChazelas EPlancoulaine SVan Der Waerden JLeproux OCharles MABailhache MGomajee RfalseIntimate partner psychological violence and children's sleep difficulties up to 5 years of age: an ELFE birth cohort.To examine the association between intimate partner psychological violence (P-IPV) from before pregnancy to 2 years after the child's birth and child's sleep patterns, i.e. sleep onset difficulty (SOD), nighttime awakenings (NA), and nighttime sleep duration (NSD) between 2 and 5 years of child's age.
