Alzheimer's Caregivers in Japan Have Lower Quality of Life Than Non-Caregivers

Sep 8, 2014

New research by Kantar Health also shows Japanese caregivers use more healthcare resources and have higher activity impairment.

NEW YORK, September 9, 2014—Caregivers of Alzheimer’s patients in Japan have lower mental and physical quality of life, have greater activity impairment, and use more healthcare resources than non-caregivers, according to new findings from Kantar Health’s National Health and Wellness Survey. The research will be presented today at the 6th ISPOR (International Society for Pharmacoeconomics and Outcomes Research) Asia Pacific Meeting in Beijing.

“Japan has the fastest aging population as well as the highest life expectancy in the world. These two factors make it important for the healthcare industry to take a closer look at diseases associated with aging, especially Alzheimer’s disease,” said Takashi Fukuda, Ph.D., Research Managing Director at the National Institute of Public Health in Japan and a co-author of the study. “Not only do we have to look at how diseases associated with aging affect patients, but we also have to look at the burden on the patients’ caregivers to understand the overall societal burden.”

“After controlling for variables such as demographics, the data showed that Alzheimer’s caregivers had lower mental and physical quality of life and more healthcare resource utilization. Caregivers averaged six visits to their healthcare providers in the past six months compared with four visits for non-caregivers,” said Yasuyuki Okumura, Ph.D., Institute for Health Economics and Policy, Tokyo, Japan. “Adding to caregivers’ mental quality-of-life burdens is the fact that they have a higher severity of depression.”

About the National Health and Wellness Survey (NHWS)

The study’s results were drawn from the 2012 Japan NHWS, a nationally representative, self-administered survey conducted annually. Topics covered include the health status, attitudes, behaviors and outcomes among adults 18 or older.               

Kantar Health conducts the NHWS in the U.S., Europe, Asia and Latin America. The survey is the largest self-reported dataset in the healthcare industry.
