Delayed medical care is a negative consequence of the COVID-19 pandemic for families with young children. Our study used data from the Accessing California Communities' Experiences with Safety net Supports (ACCESS) survey, a cross-sectional study that assessed experiences with safety-net programs among working families with low incomes (n=491). From August 2020 to May 2021, we conducted interviewer-administered surveys of low-income families with young children (ages zero to eight) in California and asked questions about whether participants had delayed medical care for their children or themselves. We found that delaying care for children was associated with lack of childcare and with the child having pre-existing conditions. Delaying parental medical care was associated with lack of childcare, experiences of racism, government mistrust, and perceptions of welfare stigma. These results suggest that health care access may be improved through a focus on supporting childcare systems and addressing structural racism.
