Nearly 45,000 people in the US die each year because of a lack of healthcare insurance, according to a new report.

The study conducted by Harvard Medical School and Cambridge Health Alliance has also found that one American is dying every 12 minutes because they do not have access to adequate healthcare, reports.

The study analysed data from national surveys and health examinations, covering more than 9,000 people, and found a direct link with a rise in premature deaths when healthcare is delayed because of a lack of insurance, the news service said.

University of Washington professor and lead author of the study Andrew Wilper said that the uninsured suffered greater risks.

“The uninsured have a higher risk of death compared to the privately insured, even after taking into account socioeconomics, health behaviours and baseline health,” Wilper said.
