Overall Impact of COVID-19 Outbreak in Children with Functional Abdominal Pain Disorders: Results From the First Pandemic Phase.

OBJECTIVE: We aimed to assess how the first phase of COVID-19 pandemic influenced symptoms in children with functional abdominal pain disorders (FAPDs) and to characterize their quality of life (QoL), anxiety and global health. METHODS: This was a multicenter, observational, international study conducted between April and July 2020 at 6 different referral centers. Children diagnosed with FAPDs between October 2019 and February 2020 were enrolled and prospectively interviewed at 4 months of follow-up during the first pandemic phase (Quarantine group). Patients were asked to complete PedsQL 4.0 Generic Core Scale and PROMIS Anxiety and Global Health questionnaires. A cohort of children diagnosed with FAPDs between October 2018 and February 2019 was used as a Control group. RESULTS: Three-hundred-fifty-six children were enrolled of whom 180 (Mean age at diagnosis: 14  ±â€Š 2.8 years) in the Quarantine group and 176 (Mean age at diagnosis: 13  ±â€Š 2.8 years) in the Control group. At 4 months of follow-up, we observed a significant reduction of children reporting ≥5 episodes of abdominal pain per month when compared to baseline, in both groups (Quarantine group: 63.9% vs 42.2%, p < 0.001; Control group: 83.5% vs 50%, p < 0.001). The Quarantine group had median QoL values of 84.8 with 16.6% of children showing high anxiety values and 55% having decreased global health score. CONCLUSIONS: We demonstrated symptoms' improvement at 4 months of follow-up in both cohorts. During the first months of the COVID-19 quarantine children with FAPDs showed satisfactory QoL and anxiety scores, suggesting positive effects of school closure and increased parental attention.
