Is Subjective Cognitive Decline Associated with Behavioral Health Outcomes Among Mothers?

Studies suggests that pregnancy can alter the maternal neurological function of the brain (i.e., result in cognitive decline) in a way that remains prevalent well into middle and older adulthood. However, little research has explored these changes and how they might affect behavioral health outcomes, such as substance use and depression.

We merged data from the 2016, 2017, and 2018 Behavioral Risk Factor Surveillance System (BRFSS) surveys, with a final analytic sample of 1330 female participants (649 participants were mothers). Chi-square tests or t-tests were used to examine differences in demographic and health characteristics of the sample by subjective cognitive decline (SCD) status. To test the study hypotheses, three generalized linear mixed models were estimated with a logit link.

SCD was not associated with alcohol misuse among mothers (aOR = 0.27, p = 0.23). Mothers with SCD were more likely to smoke (aOR = 3.33, p = 0.01) and experience mental distress (aOR = 6.59, p < 0.001) than those without SCD.

Interventions aimed at supporting mothers should consider how existing mental health and tobacco cessation programs can be adapted to better serve this population and should aim to identify those that may have early signs of early signs of neurodegenerative conditions.
