^aCaregiver was defined as a participant who answered “yes” to “Are you currently providing care on an ongoing basis to a family member with a chronic illness or disability? This would include any kind of help such as watching your family member, dressing or bathing this person, arranging care, or providing transportation.”

^bA person with self-reported diabetes was defined as a participant who answered “yes” to “Has a doctor or other health professional ever told you that you had diabetes or high blood sugar?”

^cCategories are not mutually exclusive. Participants with missing data for an outcome that was included in the diabetes score were placed in the high strain (score ≥3) category if they had a score of at least 3 despite a missing response.
