This study evaluated the public’s perception of how increasing levels of GDP spending on healthcare impact average life expectancy, according to a representative sample of adults in the United States. Statistical analyses correlated the responses with selected demographic variables. The results show that the sample placed greater importance on advances in healthcare than on public health efforts for explaining improved life expectancy over the past century. The sample perceived that increased spending on healthcare through 100% of GDP would continue to promote higher life expectancy. As to why life expectancy has improved, 72% of men and 68% of women (p = 0.0004) attributed it to healthcare. The second most common reason given was lifestyle (10%), followed by diet (9%), education (2%), sanitation (2%), and other (6%). A positive linear relationship was observed between percent of GDP spent on healthcare and perceived life expectancy for all education groups, but the estimated slope showing the relationship decreased with increasing education. In addition, estimated life expectancy when 0% of the GDP was spent on healthcare increased from 30.4 for those with some high school to 40.4 for those with some college, to 45.8 for those with a college degree, to 48.8 for those with a doctoral or professional degree. With greater importance placed on healthcare than public health, over spending on healthcare as opposed to public health will likely result in declining health outcomes and life expectancy in the future.
