The lack of medical coverage in America is a serious problem as approximately 50 million people were uninsured all through 2010. But the U.S. Supreme Court on Thursday ruled the Patient Protection and Affordable Care Act, which was passed in 2010, was constitutional. The legislation, once implemented in its entirety, is expected to cover 30 million Americans currently lacking coverage.

The lack of medical insurance has had grave consequences on individuals and the nation. In 2010 alone, 26,100 people died because they had no health insurance — that is 502 preventable deaths a week. However, some states fared better than others. Based on the latest report by Families USA, a health care consumer advocacy group, 24/7 Wall St. identified the 10 states with the highest number of deaths per 100,000 people due to a lack of insurance.

Not surprisingly, nearly all of the states with the most residents dying due to a lack of insurance also had high numbers of uninsured residents. Seven of the states on the list were among the 10 states with the highest percentage of people without health coverage. Seven of the states were also in the bottom 10 for the lowest rates of private insurance coverage.

People without health insurance often forgo medical treatment for different reasons. According to Families USA, a supporter of President Obama’s health care reform law, uninsured adults are nearly four times more likely than insured adults to delay or avoid preventive care screening due to cost. Uninsured adults are also nearly seven times more likely to go without needed care due to cost than privately insured adults.

“You still see a very, very strong correlation between uninsurance and poor healthcare outcomes — including mortality — and [that is] because people aren’t getting the type of care that they need,” Kim Bailey, the research director for Families USA, told 24/7 Wall St.

Many of the states with high death rates due to a lack of insurance also were among the poorest states in the country. The top seven states on this list also are among the 10 states with the highest poverty rates. Every state on this list is in the top half.

Poor health also appears to play an important role. States with high death rates due to lack of insurance had a high percentage of people with lifestyle-related risk factors for poor health. Of the states on our list, five of them have among the 10 highest percentages of smokers and among the 10 lowest percentages of people who eat vegetables at least three times a day. Four have among the 10 highest proportions of overweight or obese adults. Seven states on the list were in the bottom 10 in terms of life expectancy.

Based on Families USA’s report, “Dying for Coverage: The Deadly Consequences of Being Uninsured,” 24/7 Wall St. identified the 10 states with the highest number of deaths from being uninsured per 100,000 residents. 24/7 Wall St. reviewed the methodology used by Families USA, first developed in 2002 by the Institute of Medicine, to determine excess mortality from being uninsured. This method considers the proportion of people who are insured and uninsured, the mortality risks for the uninsured and the number of expected deaths from a hypothetical fully insured population. 24/7 Wall St. also identified poverty rates and median income by state, provided by the U.S. Census Bureau. The Kaiser Family Foundation’s website — Statehealthfacts.org — provided health-related data, including life expectancy, obesity and diabetes rate.

These are the 10 states dying for health coverage.
