Objective: To evaluate whether the risk of long COVID among individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy differs from that of individuals who were not pregnant at time of virus acquisition.
Methods: We conducted a multicenter observational cohort study at 79 NIH RECOVER (Researching COVID to Enhance Recovery) sites. Individuals assigned female at birth aged 18-45 years with an index (first) SARS-CoV-2 infection on or after December 1, 2021, were included. The exposure was pregnancy (any gestational age) at the time of index SARS-CoV-2 infection. The primary outcome was long COVID 6 months after index infection, defined as RECOVER-Adult Long COVID Research Index score 11 or higher based on a detailed symptom survey. To account for confounding and differential selection between participants who were pregnant and not pregnant at infection, propensity score-matching methods were used to balance the groups on variables potentially associated with both pregnancy status and long COVID.
Results: Overall 2,423 participants were included; 580 (23.9%) were pregnant at index SARS-CoV-2 infection. The median age at infection was 33 years (interquartile range 28-38 years), and 2,131 of participants (90.0%) with known vaccination status were vaccinated. After propensity score matching, the adjusted long COVID prevalence estimates 6 months after index infection were 10.2% (95% CI, 6.2-14.3%) among those pregnant at infection and 10.6% (95% CI, 8.8-12.4%) among those not pregnant at infection. Pregnancy was not associated with a difference in adjusted risk of long COVID (adjusted risk ratio 0.96, 95% CI, 0.63-1.48).
Conclusion: Acquisition of SARS-CoV-2 during pregnancy was not associated with a differential risk of long COVID at 6 months compared with similar-aged individuals who acquired SARS-CoV-2 outside of pregnancy.
