Insights
Financial stress during pregnancy is linked to excessive gestational weight gain (GWG). This finding highlights the importance of addressing stress in prenatal care to improve maternal and fetal outcomes.
Area of Science:
- Obstetrics and Gynecology
- Public Health
- Maternal-Fetal Medicine
Background:
- Psychosocial stress and gestational weight gain (GWG) are independently linked to adverse maternal and fetal outcomes.
- Previous studies on the association between psychosocial stress and GWG have produced inconsistent results.
- This study aimed to clarify the relationship between psychosocial stress and GWG in a large population.
Purpose of the Study:
- To evaluate the association between maternal psychosocial stress and gestational weight gain (GWG) in a large, population-based cohort.
- To investigate how different domains of psychosocial stress (traumatic, financial, emotional, partner-related) relate to GWG.
- To provide evidence for informing prenatal care initiatives.
Main Methods:
- Utilized data from the Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 7 questionnaire (2012-2015).
- Assessed maternal psychosocial stress across four domains (traumatic, financial, emotional, partner-related).
- Categorized GWG into inadequate, adequate, or excessive based on pre-pregnancy BMI and total GWG, using Institute of Medicine guidelines. Employed multinomial logistic regression, accounting for complex survey design.
Main Results:
- Included 119,183 participants who delivered at ≥37 weeks gestation with available GWG data.
- Financial stress was significantly associated with an increased risk of excessive GWG (RRR 1.09 [95%CI: 1.02-1.17]) after adjusting for confounders.
- No significant association was found between exposure to any stressor group and an increased risk of inadequate GWG.
Conclusions:
- Financial stress during pregnancy is associated with a higher risk of excessive gestational weight gain in the US.
- Understanding the impact of stress on GWG is crucial for developing targeted prenatal care strategies.
- This research underscores the need to incorporate stress management into routine prenatal care.
Objective:
Both psychosocial stress and gestational weight gain are independently associated with adverse maternal and fetal outcomes. Studies of the association between psychosocial stress and gestational weight gain (GWG) have yielded mixed results. The objective of this study was to evaluate the association between psychosocial stress and GWG in a large population-based cohort.
Methods:
Data from the nationally representative Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 7 questionnaire 2012-2015 was utilized. Maternal psychosocial stress was assessed through response to questions designed to examine four domains of psychosocial stress (i.e., traumatic, financial, emotional, partner-related) three months prior to or during pregnancy. GWG was categorized using pre-pregnancy BMI and total GWG into inadequate, adequate, or excessive according to the Institute of Medicine's GWG guidelines. Multinomial logistic regression was used to evaluate the association between psychosocial stressors and adequacy of GWG. Analyses took into account complex survey design.
Results:
All respondents who delivered ≥ 37 weeks gestation with GWG information available were included in the analysis (n = 119,183). After adjusting for confounders, patients who reported financial stress were more likely to experience excessive versus adequate GWG (RRR 1.09 [95%CI: 1.02-1.17]). Exposure to any of the stressor groups did not significantly increase the risk of inadequate GWG.
Conclusions:
This large, population-based study revealed that among pregnant people in the US, exposure to financial stress is associated with higher risk of excessive GWG. Understanding the role stress plays in GWG will help to inform initiatives targeting this important aspect of prenatal care.
