Note: Multiracial race includes “American Indian or Alaska Native”, “German”, and “Italian”. Private insurance includes “PPO or HMO purchased through an employer” or “Other: Anthem”. Public insurance includes “Medical”, and “Medicare”, “Tricare, VA or Military”. If participants responded having both private and public health insurance, they were grouped under private health insurance.

We considered US Census Health Insurance Coverage and CDC Health Insurance Coverage guidelines for private and public health insurance categories, however note that we grouped “Tricare, VA or Military” as public health insurance.

Of the 3 who reported “Tricare, VA or Military” health insurance (we can group them as private or public health insurance - currently set as public health insurance in Table 1)
