Impact of the COVID-19 pandemic on mental healthcare consultations among children and adolescents in Norway: a nationwide registry study

ABSTRACT BACKGROUND There have been widespread concerns about the impact of the COVID-19 pandemic and its associated restrictions on children’s and adolescent’s mental health. While some studies have found increasing rates of mental health problems during the pandemic, other evidence suggest that mental symptoms and disorders were increasing before the pandemic. This study compared trends in mental healthcare use during the first 15 months of the pandemic with similar pre-pandemic trends. METHODS Consultations related to mental symptoms and disorders were identified through national registries from primary and specialist healthcare services, including hospitalizations, covering the entire population of children 6-18 years in Norway (N=908 272). The monthly likelihood of having a consultation or hospitalization related to overall mental health problems, and specific diagnoses for depression, anxiety, ADHD and sleep problems were plotted from January 2020 to May 2021 and compared to trends over the same period between 2017-2019 using event study and difference-in-difference designs. FINDINGS We found reductions in consultations for mental health symptoms and disorders in primary and specialist healthcare during the first weeks of lockdown in 2020. This decline was temporary, and volumes of consultations quickly returned to pre-pandemic levels. However, during fall 2020, consultation volumes related to mental health in primary care increased. This increase persisted into the winter of 2021 but levelled off by the last month of the sample period. The increase in consultation volumes was about 50 % compared to the pre-pandemic period. We did not find increases in consultations in specialist healthcare, except for hospitalizations. CONCLUSION We found an increase in primary care consultation volumes related to mental health among children that depart from the previously established increases over recent years. We did not see similar increases in consultations in the specialist healthcare. It is unknown whether increases in primary care consultations represent milder cases, which primarily do not need specialist treatment, or if the stability in specialist healthcare consultations reflects capacity problems or timelags in referrals.
