Analyses from linear regression models include representativeness weights and correction for complex survey design. Models adjusted for baseline outcome, age, gender, race/ethnicity, education, health insurance, and family size. Estimated scores from predictive margins

MCS, mental component score. Mean = 50, standard deviation = 10, higher scores indicates better mental health

PCS, physical component score. Mean = 50, standard deviation = 10, higher scores indicates better physical health

Self-Rated Health scored as 1=excellent, 2=very good, 3=good, 4=fair, or 5=poor

K6, Kessler 6 measure of non-specific psychological distress (range 0–24 with higher scores indicating more distress

PHQ2, Patient Health Questionnaire 2-Item measure of depressive symptoms (range: 0–6 with higher scores indicating more depressive symptoms

SF-6D, Short Form – Six Dimension measure of health utility (range 0.345 to 1, with higher scores indicating better health utility)
