Both insufficient and long sleep duration increase risk of osteoarthritis development, reveals study

A new study published in the journal of BMC Public Health showed that both inadequate and longer sleep durations increased osteoarthritis (OA) risk in the middle-aged and older cohorts. One of the most common types of arthritis and a major contributor to disability is osteoarthritis. There is still uncertainty on the relationship between sleep length and OA.

Waist circumference has been linked to both OA and sleep duration, according to studies. Thus, Guoliang Ma and colleagues carried out this study to look at the relationship between sleep duration and OA as well as the role that waist circumference plays as a mediator. Adults who took part in the National Health and Nutrition Examination Survey (NHANES) between 2011 and 2018 made up the study sample. Less than 7 hours is considered insufficient sleep, 7 to 8 hours is seen adequate, and 9 hours or more is deemed to be a lengthy sleep period.

In this investigation, 3 models were used. In contrast to Model 2, which was adjusted for sex, age, and race, Model 1 was not modified for any variables. All factors have been taken into consideration in Model 3. The relationship between sleep duration and OA was investigated using multivariable logistic regression, subgroup analysis, interaction testing, and smoothing curve fitting. Using mediation analysis, the mediating role of waist circumference in the relationship between sleep duration and OA was examined.
