Types of Exercise and Risk of Developing Dementia in Older Japanese Community-Dwelling Adults: A Prospective Study.

Chronic non-cancer pain (CNCP) has been defined as pain that lasts longer than 3 months and continues after the considered normal time of tissue healing. People affected by chronic pain experience pain on most days, or every day, which impairs their daily activities. Also, chronic pain is in the top ten leading causes of disease burden and disability worldwide by the Global Burden of Disease Reviews, including low back pain, headache and neck pain. Worldwide, it is estimated that 30% of the population suffers from chronic pain, and that explains up to 20% of healthcare visits. In the United Kingdom (UK), it is estimated that 43% of people are affected by chronic pain and in about 15% of people, the pain is considered to be severe and disabling, causing significant impairment in their daily activities. Despite the limited evidence that opioids are effective in the treatment of chronic pain, opioid medication has been the first line of treatment for chronic pain for many years. A recent systematic review identified that 31% of the patients with CNCP are prescribed opioids, with strong opioids being prescribed 18% more frequently than weak opioids 8.5%. Epidemiological studies conducted in the UK, United States (US), Canada and Australia have raised awareness of the increase in opioid prescriptions in the last decades alongside misuse of prescribed opioids and the significant rise in related deaths. Furthermore, long-term opioid treatment has been associated with serious harms such as falls and fractures, road accidents, sleep apnea, hyperalgesia, immunosuppression, chronic constipation, higher risk of myocardial infarction and erectile dysfunction. Likewise, the evidence synthesis from the Centers for Disease Control in the US showed that opioid prescriptions were associated with addiction, overdose and death.
