0859 Types Of Childhood Maltreatment And Sleep Regulation During Pregnancy
Bibliographic record
Abstract
Abstract Introduction Pregnant women with history of childhood maltreatment would have around 2-fold increased odds of poor subjective sleep in comparison to pregnant women without history of trauma (Gelaye et al., 2015). Our aim was to evaluate whether different types of childhood maltreatment were associated with poorer subjective and objective sleep regulation during the second trimester of pregnancy. Methods Sleep regulation between 18-20 weeks of gestation was assessed in a sample of 55 expectant mothers, including 31 women exposed to childhood maltreatment. Three measures of sleep were administered: 7-day actigraph measures (Mini-Mitter/Respironics), 7-day sleep diary and the completion of Pittsburgh Sleep Quality Index. Childhood maltreatment was assessed using the Chilhood Trauma Questionnaire. Generalized linear regression models were used to examine the associations between sleep measures and types of childhood maltreatment after adjusting for confounding variables (e.g., maternal age, maternal wellbeing, education attainment and family income). Results Among the 31 participants with history of childhood maltreatment, 71% (n=22) reported emotional abuse, 26% (n=8) physical abuse, 39% (n=12) sexual abuse, 42% (n=13) emotional neglect and 65% (n=20) physical neglect. Pregnant women with childhood emotional abuse had around 2.8 higher score on PSQI in comparison to pregnant women without childhood emotional abuse (P<0.003). For objective sleep measures, pregnant women with childhood sexual abuse had around 1 hour less of nocturnal sleep (P<0.004), 30 minutes more nocturnal awakenings (P<0.03) and 6% less of sleep efficiency (P<0.01) compared with pregnant women without childhood sexual abuse. Conclusion Emotional abuse during childhood was associated with poorer perceived sleep quality during the 2nd trimester of pregnancy while childhood sexual abuse was particularly associated with objective measures of sleep regulation. Future larger studies are needed to confirm the impact of the different types of childhood maltreatment on maternal sleep quality during pregnancy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
