Do sleep disruptions raise risk of joint issues?
Factors associated with sleep could increase the risk of knee and hip osteoarthritis.
In a study published in Arthritis Care & Research, investigators used data from the UK Biobank to examine the relationship between sleep duration and disruption and knee and hip osteoarthritis as well as total joint arthroplasty.
The investigators found that the participants who achieved less than six hours of sleep per night were more likely to experience osteoarthritis and joint replacement surgery compared with those who achieved seven hours of sleep. Those who reported usually experiencing insomnia or sleeplessness were more likely to experience both endpoints compared with those who never or rarely experienced the sleep disorders. In addition, the participants who were night-shift workers had a greater likelihood of developing knee osteoarthritis and total knee arthroplasty. Although adjustment for body mass index reduced the associations, short sleep duration, insomnia and sleeplessness as well as night-shift work remained correlated with their respective endpoints.
The results of the study highlighted that sleep disruptions could play a role in the cartilage degeneration linked to knee and hip osteoarthritis through obesity and obesity-independent pathways.
