WASHINGTON, July 22 (UPI) -- U.S. researchers need to include representative samples of ethnically diverse populations in their studies to better reflect the population, a journal says.
A supplemental issue of The Gerontologist says the U.S. Census Bureau predicts that non-white minorities will make up 42 percent of the country's population age 65 and older by 2050, yet many studies don't reflect that.
"The cultural-historical background and sociopolitical conditions of each diverse group poses unique challenges in developing successful recruitment and retention methods and strategies," Peggye Dilworth-Anderson, a former president of The Gerontological Society of America, says in the issue's introduction. "This critical collection of articles demonstrates important theoretical and conceptual frameworks that seek to address the shortcomings of previous models of using diverse populations."
The publication also identifies several strategies that scholars can employ in their work to include underrepresented groups.
