    Abstract:
    BACKGROUND: Studies investigating the patterns or predictors of psychological distress in expecting and postpartum mothers affected by previous prenatal loss, are limited. The study objectives were to explore longitudinal trajectory patterns of depressive and anxiety symptoms in mothers affected by previous prenatal loss from early in a subsequent pregnancy up to pre-adolescence, and to identify early factors predictive of elevated symptom trajectory patterns. METHODS: A total of 2854 mothers from the Avon Longitudinal Study of Parents and Children self-identified as having experienced a previous prenatal loss. A latent class analysis identified trajectory patterns of symptoms across 10 timepoints from 18-weeks' gestation up to 134-months postpartum, multivariate regression analysis identified predictors of elevated symptom trajectories, and hierarchical regression analysis determined predictive accuracy between predictors and elevated trajectory patterns. RESULTS: Three distinct longitudinal trajectory patterns of depressive and anxiety symptoms reflected low (54%), sub-clinical (34%), and clinical symptoms (12%). Key factors that predicted elevated symptom trajectory patterns better than increased symptom scores early in subsequent pregnancy include history of severe depression or other psychiatric problem, experiencing three or more stressful events from mid-pregnancy, inadequate social support, history of induced abortion, and history of abuse. Predictive accuracy of elevated trajectories was 0.542 (depression) and 0.432 (anxiety). LIMITATIONS: Generalizability may be compromised by attrition, under-reporting, and recall bias. CONCLUSION: Including factors predictive of long-term sub-clinical or clinical depressive and anxiety symptoms in early assessments will improve clinician's ability to identify mothers who may benefit from immediate and/or ongoing monitoring, and psychotherapeutic intervention after prenatal loss.
