Newswise — Researchers from the Oregon Research Institute (ORI) and Florida Atlantic University (FAU) are the first to demonstrate statistically significant links between self-reported regular use of prescription drugs for pain and/or sleep, and longitudinal risk of frailty in adults ages 65 and older. Frailty consists of deficits in a variety of functional measures, and is a reliable predictor of loss of independence, increased use of health care resources, and mortality. The possible implications of current research findings are especially serious given that it is common for older Americans to use two or more prescription drugs at the same time and many of these prescription drugs are for pain and sleep, including analgesics and sedatives.
Results, published online in the Journal of the American Geriatric Society, estimate long-term frailty risks and rank the long-term risks of two classes of prescription drugs. Researchers found over eight years of follow-up, those who self-reported regular use of prescription drugs for pain and sleep had a 95 percent increased risk of frailty compared to those who did not report regular use of these drugs. For regular prescription drug use for pain only or for sleep only, the increased risks were 58 percent and 35 percent, respectively.
Co-authors Gulcan Cil, Ph.D., associate scientist, ORI, Juyoung Park, Ph.D., associate professor in FAU’s Phyllis and Harvey Sandler School of Social Work within the College for Design and Social Inquiry, and senior scientist Andrew Bergen, Ph.D., ORI, analyzed data from the Health & Retirement Study (HRS), a nationally representative longitudinal cohort of older Americans. For their analysis, they selected a large cohort (N=7,201) of community-living non-frail older adults (age 65 to 104, mean 72, median 70) from the HRS. Analyses were adjusted for demographics and other drug use.
“Co-use of multiple prescription medications is a growing phenomenon, especially among older adults,” said Park. “Geriatric medicine societies, including the American Geriatric Society, have developed guidelines to help prescribers avoid potentially inappropriate prescribing or PIP, which requires assessment of several types of PIP, including the benefits and risks associated with certain drug classes.”
“Our study shows that regular self-reported use and co‐use of prescription drugs for pain and for sleep are significantly associated with increased incidence of frailty,” said Bergen. “We recommend further research to estimate the frailty risk of pain and sleep measures and of prescription pain and sleep drugs.”
The HRS dataset used by the researchers is sponsored by the National Institute on Aging (NIA) of the National Institutes of Health and the Social Security Administration (SSA) and is conducted by the University of Michigan. RAND HRS data products used in this study are produced by RAND Center for the Study of Aging with funding from the NIA and SSA.
Park will present this work at the Gerontological Society of America Annual Scientific Meeting (geron.org/2019) on Nov. 16 in Austin, Texas.
About the Oregon Research Institute
Founded in 1960, Oregon Research Institute (ORI) is a charitable 501(c) 3 research center, dedicated entirely to understanding human behavior and improving the quality of human life. Funded by research grants from the National Institutes of Health and by the United States Department of Education, ORI scientists study such topics as childhood obesity and behavioral problems, promoting health across the age span, preventing and treating teen substance use and abuse, and understanding and preventing eating disorders. Emerging areas include genetics, opioid addiction, Alzheimer's disease, and health economics. See www.ori.org.
About Florida Atlantic University: Florida Atlantic University, established in 1961, officially opened its doors in 1964 as the fifth public university in Florida. Today, the University, with an annual economic impact of $6.3 billion, serves more than 30,000 undergraduate and graduate students at sites throughout its six-county service region in southeast Florida. FAU’s world-class teaching and research faculty serves students through 10 colleges: the Dorothy F. Schmidt College of Arts and Letters, the College of Business, the College for Design and Social Inquiry, the College of Education, the College of Engineering and Computer Science, the Graduate College, the Harriet L. Wilkes Honors College, the Charles E. Schmidt College of Medicine, the Christine E. Lynn College of Nursing and the Charles E. Schmidt College of Science. FAU is ranked as a High Research Activity institution by the Carnegie Foundation for the Advancement of Teaching. The University is placing special focus on the rapid development of critical areas that form the basis of its strategic plan: Healthy aging, biotech, coastal and marine issues, neuroscience, regenerative medicine, informatics, lifespan and the environment. These areas provide opportunities for faculty and students to build upon FAU’s existing strengths in research and scholarship. For more information, visit www.fau.edu.
