Researchers in the U.K. report 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% of people 65 years of age and older experiencing daily pain. Widespread pain that affects multiple areas of the body —- the hallmark feature of fibromyalgia —- affects 15% of women and 10% of men over age 50 according to previous studies.

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.
