Elevated risk for obsessive–compulsive symptoms in women pregnant during the COVID-19 pandemic

The COVID-19 pandemic has led to a public mental health crisis with many people experiencing new or worsening anxiety. Fear of contagion and the lack of predictability/control in daily life increased the risk for problems such as obsessive–compulsive disorder (OCD) in the general population. Pregnant women may be particularly vulnerable to such pandemic-related stressors yet the prevalence of OC symptoms in this population during the pandemic remains unknown. We examined the prevalence of OC symptoms in a sample of 4451 pregnant women in the USA, recruited via targeted online methods at the start of the pandemic. Participants completed self-report measures including the Obsessive–Compulsive Inventory-Revised and the Pandemic-Related Pregnancy Stress Scale. Clinically significant OC symptoms were present in 7.12% of participants, more than twice as high as rates of peripartum OCD reported prior to the pandemic. Younger maternal age, income loss, and suspected SARS-CoV-2 infection were all associated with higher OC symptoms. Two types of pregnancy-specific stress, pandemic-related and pandemic-unrelated, were both associated with higher levels of OC symptoms. Pandemic-related pregnancy stress predicted OC symptoms even after controlling for non-pandemic-related, pregnancy-specific stress. Elevated rates of OC symptoms were observed in women pregnant during the pandemic, particularly those experiencing elevated pandemic-related pregnancy stress. This type of stress confers a distinct risk for OC symptoms above and beyond pregnancy-specific stress and demographic factors. Healthcare providers should be prepared to see and treat more peripartum women with OC symptoms during this and future public health crises.
