Americans who have health coverage tend to have healthier behaviors
, according to the Gallup-Healthways Well-being Index
Overall, the index found 80 percent of American adults younger than 65 have health insurance. Those with health coverage are more likely to eat healthily and less likely to smoke than those without coverage
While those with coverage are also more likely to exercise, the difference is not large.
The difference between the two groups in terms of smoking was the most pronounced. Just 20 percent of those with health coverage smoke, while 36 percent of those without insurance smoke, according to the index.
It is unclear why those with health insurance tend to have healthier habits, according to Gallup. Those who care about their health may be more likely to purchase insurance, or it could be that smokers have higher premiums and may not be able to afford coverage.
In addition, employer-based wellness programs may impact the findings, since most individuals with health coverage receive it through their employer
