Restless sleep main cause of widespread pain in adults over 50
Researchers in the UK have found that non-restorative sleep is the strongest, independent predictor of widespread pain onset among adults over the age of 50.
According to the study, anxiety, memory impairment, and poor physical health among older adults may also increase the risk of developing widespread pain.
Muscle, bone and nerve (musculoskeletal) pain is more prevalent as people age, with up to 80 percent of people 65 years of age and older experiencing daily pain.
Widespread pain that affects multiple areas of the bodyaEuro"the hallmark feature of fibromyalgiaaEuro"affects 15 percent of women and 10 percent of men over age 50 according to previous studies.
Led by Dr. John McBeth from the Arthritis Research UK Primary Care Centre, Keele University in Staffordshire, this newly published population-based prospective study identified factors that increase the risk of the development of widespread pain in older adults.
The team collected data on pain, psychological and physical health, lifestyle and demographic information from 4326 adults over the age of 50 who were free of widespread pain at the start of the study (1562 subjects reported no pain and 2764 had some pain). These participants were followed up three years later for the development of widespread pain.
Results show that at follow-up, 800 (19 percent) reported new widespread pain. The development of new widespread pain was greater in those with some pain at the start of the study; 679 (25 percent) of those with some pain and 121 (8 percent) of those with no pain at the start developed new widespread pain at three year follow-up.
Analyses determined that pain status, anxiety, physical health-related quality of life, cognitive complaint and non-restorative sleep were associated with increased risk of widespread pain development, after adjusting for osteoarthritis (OA). Increasing age was associated with a decreased likelihood of the development of widespread pain.
The study is published in Arthritis and Rheumatology (formerly Arthritis and Rheumatism), a journal of the American College of Rheumatology (ACR).
