| Popis: | Purpose To determine common temporal change patterns (i.e., trajectories) of perceived antenatal psychological stress throughout the pregnancy, and to examine associations between these identified trajectories and neonatal birth outcomes. Methods 926 participants from a prospective cohort study of multi-ethnic Asian women from an urban setting with uncomplicated singleton pregnancies completed the Perceived Stress Scale in their first, second, and third trimesters, and just prior to parturition. Gestational age, neonatal weight, length, and head circumference were recorded at birth. Longitudinal trajectories of antenatal psychological stress were characterized with group-based trajectory modelling; associations between trajectories and neonatal outcomes were assessed with analyses of covariance and covariate-adjusted linear regressions. Results Three distinct non-fluctuating trajectories of antenatal psychological stress were identified, with 43 % of women experiencing significant levels of stress throughout the pregnancy. Women in this persistently-higher stress trajectory delivered neonates who were 57.5 g lighter and with head circumferences of 20 mm less than their counterparts in the other trajectories. Each one-point increase on the Perceived Stress Scale was associated with a decrease of 5.64 g in birthweight and a decrease of 0.4 mm in head circumference. Conclusions This study delineated three meaningful trajectories of antenatal psychological stress. The persistently-higher antenatal psychological stress trajectory, experienced by two in five women, was associated with lower birthweight and possibly smaller head circumference. While further research is needed to better appreciate the clinical relevance of these findings, it highlights the importance of psychosocial support even for healthy pregnant women with uncomplicated pregnancies in Asian settings. |
