摘要

Background

The COVID-19 pandemic was a prolonged period of traumatic stress with potentially lasting health impacts, especially for vulnerable groups including pregnant individuals. Prenatal stress has been associated with greater risk of neurodevelopmental disorders (NDD), warranting investigation of prenatal pandemic-related traumatic stress (PTS) as a risk factor for NDD.

Methods

We surveyed Kaiser Permanente Northern California (KPNC) members who were ≥ 12 weeks pregnant between June 2020 and September 2022. PTS was measured using the 10-item PTS Scale and modeled as a continuous total symptom score (range: 0–10) and binary exposure (high, ≥ 9; low, < 9). We prospectively followed children through July 2025 and linked to sociodemographic and medical characteristics, including NDD diagnoses, in KPNC electronic records. We fit Cox regression models adjusted for maternal age, race and ethnicity, insurance type, SARS-CoV-2 infection, pre-pregnancy BMI, pre-pregnancy depression, child birthyear and sex to estimate hazard ratios (HR) for any NDD and separately for autism spectrum disorder (ASD) associated with PTS and evaluated effect modification by child sex.

Results

Of 13,859 mothers, 21.1% identified as Asian, 3.0% as Black, 19.6% as Hispanic, 4.6% as Multiracial, < 1.0% as Native American or Pacific Islander, 49.0% as White, and 1.7% were of Unknown race. The mean (SD) PTS score was 3.9 (2.6) and 722 (5.2%) mothers had high PTS (≥ 9); 2,750 (19.8%) children were diagnosed with any NDD and 651 (4.7%) with ASD. Higher PTS symptom score was associated with significantly greater risk of any NDD (HR = 1.02, 95% CI = 1.01–1.04) and ASD (HR = 1.04 [1.01–1.07]) per 1-point increase in continuous score. High compared to low PTS was associated with greater risk of NDD diagnoses (HR = 1.18 [1.01–1.37]) and ASD (HR = 1.20 [0.89–1.62]), although not statistically significant for ASD. Associations did not differ by sex for NDD (HRFemales= 1.20 [0.92–1.56], HRMales= 1.17 [0.96–1.41]; interaction P = 0.78) or ASD (HRFemales= 1.31 [0.73–2.34], HRMales= 1.17 [0.82–1.65]; interaction P = 0.60).

Conclusions

Among this cohort of mothers who were pregnant during the COVID-19 pandemic, higher PTS was associated with greater risk of child NDD diagnoses. Further research is needed to investigate the potential biologic mechanisms underlying this association.
