Mental health service use among mothers and other birthing parents during the COVID-19 pandemic in Ontario, Canada.

BACKGROUND

Parents have reported increased symptoms of depression and anxiety during the COVID-19 pandemic. This study evaluated changes in mental health and addiction (MHA)-related health service use among mothers and other birthing parents during the COVID-19 pandemic.

METHODS

We conducted a repeated cross-sectional study using health administrative data in Ontario, Canada. The population included all mothers and birthing parents (≥1 child aged 1-18, no children <1 to exclude postpartum parents) between January 2016 and December 2021. We compared rates of MHA-related outpatient physician visits, hospitalizations, and emergency department (ED) visits during COVID-19 (March 2020-December 2021) to pre-COVID-19 (pre-March 2020).

RESULTS

MHA-related outpatient visit rates increased by 17 % (rate ratio (RR) 1.17, 95 % CI 1.16-1.18) during COVID-19. Monthly utilization rates remained higher than expected across the COVID-19 period. MHA-related ED visit rates remained lower than expected during COVID-19, while MHA-related hospitalization rates returned to expected levels by August 2020. The largest relative increases in MHA-related outpatient visits during COVID-19 were in mothers and other birthing parents living in higher income (RR 1.20, 95 % CI 1.19-1.22) or urban areas (RR 1.20, 95 % CI 1.18-1.21), with children aged 1-3 years (RR 1.23, 95 % CI 1.20-1.25) and with no history of MHA-related health service use (RR 1.20, 95 % CI 1.19-1.21).

LIMITATIONS: This study only captured physician-delivered MHA-related health service use.

CONCLUSIONS

The COVID-19 pandemic was associated with an increase in MHA-related outpatient visits among mothers and other birthing parents. These findings point to the need for improvements in mental health service access.
