Concordance in pregnancy planning, preconception health behaviours and health information-seeking of pregnant couples: a cross-sectional study

Introduction:Relational dynamics between partners within a couple planning pregnancy are critical to their preconception health behaviour change and are largely underexamined. Given the need for both reproductive partners to engage in beneficial preconception health behaviours and the influence couples have on each others behaviour, this study examines the concordance between pregnancy planning and preconception health behaviours and health information-seeking within reproductive partner dyads. Methods:A retrospective observational study was undertaken utilizing data from two online cross-sectional 80-item surveys administered simultaneously between December 2020 and September 2021. Eligible study participants were females or birthing people aged 18-49 living in Australia during any stage of pregnancy, and reproductive partners of those that met these criteria. The survey items covered sociodemographic characteristics, level of pregnancy planning, preconception health behaviours, health information seeking, and health history. Cohens kappa (K) (categorical variables) and interclass correlation coefficients (ICC) (continuous variables) were used to identify agreement within the couples. Results:Eighty matched dyads of pregnant females and non-pregnant partners were included. Concordance in pregnancy planning was fair (K=0.27) and was primarily seen in couples where both partners reported the pregnancy as planned (42.5%) or ambivalent (18.8%). Couples had very low similarity (ICC:0.22) in weekday alcohol consumption 3 months preconception (pregnant females: 1.2 standard drinks per day (SD1.7); non-pregnant partners: 2.5/day (SD3.5)). Approximately one quarter (26.3%) of couples reported similarities in partners attempting and succeeding in preconception health information-seeking 12 months before pregnancy. There was greater concordance in not discussing preconception health topics with GPs, including topics explicitly covered within clinical guidelines. Conclusion:There is notable discordance in couples preparation for pregnancy in many behaviours relevant to positive pregnancy outcomes, and in their health service engagement and experience. There is a clear need to provide care to both reproductive partners to ensure the best possible outcome for the future generations.
