In my most recent post at healthinsurance.org, I noted that the five states highlighted by the Kaiser Family Foundation as those with the highest percentages of residents with "declinable pre-existing conditions" under pre-ACA rules were also the five poorest states in the nation as measured by median household income. That is, by these broad measures, the sickest states are the poorest states. (Those with "declinable pre-existing conditions" are those who, according to Kaiser, would likely have been unable to obtain health insurance in the individual market prior to ACA enactment. Kaiser conservatively estimates that 27% of U.S. adults under age 65 have DPCs.)
The correlation between state wealth and health carries pretty well through the fifty states. The chart below plots the percentage of residents in each state with declinable pre-existing conditions (DPC, y-axis) against 2015 median household income, according to the Census Bureau.
