Americans who have health insurance are more likely to exercise and eat better and less likely to smoke than those who are uninsured, according to an analysis based on the Gallup-Healthways Well-Being Index.
The index, which tracks well-being in the United States, United Kingdom and Germany, is based on 200,000 interviews of 18- to 64-year-olds conducted in the first 10 months of last year.
Among those who have health insurance, 56 percent said they had at least five servings of fruits and vegetables at least four days in the last week, compared to 50 percent of those without insurance.
Insured Americans are slightly more likely to exercise; 53 percent reported they had exercised for 30 minutes or more at least three days in the last week, compared to 51 percent of uninsured Americans.
Meanwhile, 20 percent of insured Americans smoke, versus 36 percent of those who lack health insurance.
Researchers say it is unclear why people without health insurance are more likely to smoke and slightly less likely to exercise regularly and eat the recommended servings of fruits and vegetables.
