The first containment of the Sars-Cov2 pandemic had the potential to generate posttraumatic stress (PTS) symptoms in children.

The main objective of the study was to determine the prevalence of PTS symptoms within 6 weeks of the end of lockdown, in children contained between March 17, 2020 and May 11, 2020 in France.

This was a French prospective cross-sectional study between May 15 and July 2, 2020 conducted via telephone survey. Parents of children aged between 8 and 15 years were eligible. The invitation to participate was proposed through social networks (Instagram and Facebook), various local and national media, and by e-mail to the staff of our University Hospital Center. The PTS symptoms were assessed using the CRIES-13. A score of 30 and over has been confirmed as the cut-off for screening cases.

During the study period, 379 children (male, n = 207) were included, their mean age was 10.8±2.1 years. Symptoms of PTSD were identified in 17% of the children (girls 20.5%, boys 13.5%). These children were younger (p = 0.04), lacked access to a private outdoor space (p < 0.0001; OR: 7.8), had parents whose profession exposed them more to the coronavirus, and had parents who were more afraid of COVID-19.

After the first lockdown related to the pandemic crisis, children developed PTSD symptoms. The onset of such symptoms is correlated with gender, age, lockdown conditions, and parental perceptions. These last considerations were worse for pink- or blue-collar families, attesting to the subsequent intensification of health inequalities.
