Money makes less of a difference after 65, study finds
THURSDAY, April 24 (HealthDay News) -- The old saying, rich or poor, it's good to have money, appears to apply to the risk of stroke, a new Dutch study finds.
Wealthy Americans have a lower risk of stroke between the ages of 50 and 64, according to the data on the almost 20,000 participants in the ongoing University of Michigan Health and Retirement Study.
And the most probable reason why the difference vanishes at the age of 65 is that more of the poorer, more vulnerable, people have already died off, said study author Mauricio Avendano, a research fellow at the Erasmus Medical Center in the Netherlands. The report was published in the April 24 issue of Stroke.
Of the 780,000 Americans who are struck by new or recurrent strokes each year, 27 percent are under 65, according to the American Heart Association.
Avendano and his fellow researcher, M. Maria Glymour of the Harvard School of Public Health, examined the possibility that a later beneficial effect comes from the full health coverage provided by Medicare after age 65.
"It is possible that because more people have care, the differences between the wealthy and others doesn't matter as much," Avendano said. "But this is not a good explanation. We tend to think it is more an effect of what we call selective survival. There is a selection of people who reach age 65. People with low incomes are more likely to die, so when you reach age 65, you have a selected group of very healthy people."
This is the first study to assess the age patterns of wealth, income and education in stroke incidence in older Americans, he said, and also the first to report that economic status predicts stroke risk.
Many earlier reports have linked lower socioeconomic status with an increased risk of stroke. This one draws a distinction between wealth, defined as the total of all financial
