ABSTRACT
PURPOSE: Motherhood affects women's mental health, encompassing aspects of both wellbeing and illbeing. This study investigated stability and change in wellbeing (i.e., relationship satisfaction and positive affect) and illbeing (i.e., depressive and anxiety symptoms) from pregnancy to three years postpartum. We further investigated the mutual and dynamic relations between these constructs over time and the role of genetic propensities in their time-invariant stability. DATA AND METHODS: This four-wave longitudinal study included 83,124 women from the Norwegian Mother, Father, and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Data were collected during pregnancy (30 weeks) and at 6, 18 and 36 months postpartum. Wellbeing and illbeing were based on the Relationship Satisfaction Scale, the Differential Emotions Scale and Hopkins Symptoms Checklist-8. Genetics were measured by the wellbeing spectrum polygenic index. Analyses were based on random intercept cross-lagged panel models using R. RESULTS: All four outcomes showed high stability and were mutually interconnected over time, with abundant cross-lagged predictions. The period of greatest instability was from pregnancy to 6 months postpartum, followed by increasing stability. Prenatal relationship satisfaction played a crucial role in maternal mental health postpartum. Women's genetic propensity to wellbeing contributed to time-invariant stability of all four constructs. CONCLUSION: Understanding the mutual relationship between different aspects of wellbeing and illbeing allows for identifying potential targets for health promotion interventions. Time-invariant stability was partially explained by genetics. Maternal wellbeing and illbeing develop in an interdependent way from pregnancy to 36 months postpartum.
ABSTRACT
STUDY QUESTION: Do expectant parents experience increased anxiety and depression during pregnancies conceived through ART compared to spontaneous conception? SUMMARY ANSWER: Among all expectant parents in the sample, those who conceived through ART reported overall lower levels of anxiety and depression in pregnancy compared to expectant parents who conceived spontaneously, while in the subsample of parents who conceived both through ART and spontaneous conception, expectant mothers experienced increased anxiety and depression in early pregnancy following ART compared to spontaneous conception. WHAT IS KNOWN ALREADY: Previous research on expectant parents' psychosocial adjustment in response to ART has found mixed results, with some studies suggesting ART is associated with increased anxiety and depression, and other studies suggesting improved mental health or no relationship. Mixed findings may relate to the use of cross-sectional designs that do not account for confounding differences between groups, or variability in the timing of assessment. STUDY DESIGN, SIZE, DURATION: This prospective cohort study used data from the Norwegian Mother, Father and Child Cohort Study (MoBa), which includes 2960 pregnant women who underwent ART and 108 183 women who conceived spontaneously. Of these, a subsample of expectant parents had two consecutive pregnancies with one pregnancy resulting from ART and one conceived spontaneously (n = 286 women, n = 211 partners). Women self-reported their composite symptoms of anxiety and depression at two timepoints during each pregnancy (gestational weeks 17 and 30). Their partners self-reported composite symptoms of anxiety and depression at 17 weeks gestation during each pregnancy. Couples reported their relationship satisfaction at 17 weeks gestation. MAIN RESULTS AND THE ROLE OF CHANGE: Using a conventional full-cohort analysis we found that ART was associated with less total anxiety and depression and greater relationship satisfaction, compared to spontaneous conception among both women and men. However, in the subsample of parents who experienced both ART and spontaneous pregnancies, ART was associated with increased levels of maternal anxiety and depression at gestational age 17 weeks (M = 1.19), compared to spontaneous pregnancies (M = 1.15), 95% CI of the mean difference 0.006, 0.074. At 30 weeks gestation, anxiety and depression were similar across both types of pregnancies. Expectant fathers reported similar levels of anxiety and depression at 17 weeks gestation during both pregnancies. Among women relationship satisfaction was higher following ART conception than spontaneous conception. LIMITATIONS, REASONS FOR CAUTION: There is potential for selection effects in the sample, as women who have conceived through both ART and spontaneous conception in their first two pregnancies are rare. In addition, several factors that may be important predictors of mental health in this context, such as previous miscarriages and long-term infertility, were not assessed in the current study. WIDER IMPLICATIONS OF THE FINDINGS: Our findings indicate that previous discrepancies in the literature may be related to inherent differences between the groups of parents receiving reproductive treatment and those who do not. This study addresses that limitation by prospectively comparing different types of pregnancies within the same expectant parents. Earlier inconsistencies may also relate to variations in gestational age when anxiety and depression were assessed. By examining symptoms at two timepoints in each pregnancy, we were able to examine the relation between gestational age and symptoms of anxiety and depression.
