Determinants of maternal antenatal state-anxiety in mid-pregnancy: Role of maternal feelings about the pregnancy

Abstract

BackgroundThe current state of research into antenatal anxiety is lacking in a comprehensive understanding of determinants. This study aims to expand knowledge in this area, with the main objective being to determine potential determinants of maternal antenatal state-anxiety. MethodsData used for this cross-sectional study were obtained from the Prenatal Health Project: a population cohort study of 2357 women in London, Ontario. 1992 women in their second trimester met inclusion criteria for this study. The primary hypothesis was that “feelings about the pregnancy” would be a determinant of antenatal state-anxiety after controlling for other potential covariates. The abbreviated version of the Spielberger State and Trait Anxiety Inventory (STAI) was used to measure state-anxiety. Univariate analyses and multiple linear regression were performed to identify variables predictive of state-anxiety. ResultsStress, feeling unsure/unhappy about the pregnancy and having low self-esteem, low mastery and low social support from one’s partner and family were statistically significant determinants of state-anxiety during the second trimester. In addition, anxiety was found to be inversely related to gestational age. LimitationsThe two main limitations of the study were the use of a self-report screening tool (STAI) as the measure of anxious symptoms rather than a clinical diagnosis, and possible recall bias of feelings about the pregnancy. ConclusionsWe concluded that how a woman feels about her pregnancy was a determinant of state-anxiety. This study contributes knowledge aiming to help women improve their mental health during pregnancy by identifying important determinants of state-anxiety.
