Half of MDD Patients Are Unaware of Their Own Depression

Oct 18, 2012

New Results from the National Health and Wellness Survey Show Awareness Is Lowest in Japan and Brazil

NEW YORK, October 18, 2012—Many patients who screen positive for major depressive disorder (MDD) do not self-report that they are suffering from depression, according to new findings from the National Health and Wellness Survey (NHWS), conducted by Kantar Health. The NHWS measures patient responses to health-related questions to determine whether they have MDD in the United States, the top five European countries, which include France, Germany, Italy, Spain and the UK (5EU), Brazil, Japan and Russia.

The percentage of adults who screen positive for MDD ranges from 4.5% in Japan to 9.8% in Brazil, but self-reporting is low at 27% in Japan and 43% in Brazil. In the U.S., Russia and 5EU awareness is much higher among those who screen positive for MDD at 64%, 54% and 51%, respectively.

“MDD has been cited as one of the leading causes of disabilities worldwide; it decreases a person’s ability to function and leads to other medical problems,” said Michael Fronstin, General Manager, Health Outcomes, at Kantar Health. “The MDD population is relatively young, so early diagnosis and adequate support could result in better long-term health outcomes.”

MDD sufferers are more aware of and report higher levels of insomnia, anxiety and pain, and they tend to be younger than patients without MDD. People who screen positive for MDD report significantly more hospitalizations and visits to the emergency room than people without MDD. Their mental quality of life is significantly lower compared with the general population, with scores ranging from 28.5 in Japan (versus 47.8 for the general Japanese population) to 35.4 in Brazil (versus 46.9 in the general Brazilian population).

“Effective and affordable treatments for depression are available, even in emerging markets,” Fronstin said. “Educating patients on the symptoms of MDD may raise their awareness and encourage them to visit their healthcare provider and receive appropriate treatment.”
