A study conducted by Scripps researchers and published this week in the New England Journal of Medicine shows that direct-to-consumer genetic testing "did not result in any measurable short-term changes in psychological health, diet or exercise behavior, or use of screening tests." The researchers surveyed about 2,000 people five months after they received results from DTC genetic tests, covering 22 different conditions including Alzheimer's disease, diabetes, and several cancers, the Associated Press says. "Consumers who get their DNA tested for health risks take the results in stride. But they're also not inspired to eat better or exercise more," the AP adds.
