AbstractBackground: Pregnancy anxiety increases the risk of preterm birth but less is known about the impacts on glucose intolerance during pregnancy, such as gestational diabetes mellitus (GDM). The present study examined the relationship between pregnancy anxiety and the risk of GDM in a prospective cohort Centering and Racial Disparities (CRADLE) study of racially diverse pregnant women in the United States. Methods: This is a prospective analysis among racially diverse pregnant women in the United States who enrolled in the CRADLE study. Pregnancy anxiety was assessed twice using the Pregnancy-Specific Anxiety Scale (PSAS): the baseline survey at <20 gestational weeks (GW) and the second survey at >30 GW. GDM was screened at 24-30 GW and diagnosed based on the Carpenter and Coustan criteria. The associations of baseline PSAS score (>9 [median] versus ≤9) and PSAS score change with GDM risk were estimated using multivariable logistic regressions with adjustment for potential confounders. Results: Among a total of 2,310 women (40.74% Black, 20.91% Hispanic), 154 (6.67%) developed GDM. No association was found between baseline PSAS and GDM (adjusted odds ratio [OR]: 0.99; 95% confidence interval [CI]: 0.70-1.42) after adjusting for confounders. Individuals with an increased PSAS during pregnancy had 52% higher GDM risk (adjusted OR: 1.52, 95% CI: 1.04-2.23) compared with those with no change or decreased scores. Conclusions: Pregnant individuals who increased their pregnancy-specific anxiety level during pregnancy had a higher risk of developing GDM. Clinical Trials Registration Identifier: NCT02640638.
