J Rheumatol: Association between increased waist circumference in adult knee osteoarthritis patients and reduced risk of physical function

The study looked at the association between eight-year changes in waist circumference (WC) in adult knee osteoarthritis (OA) patients and high-risk populations and the risk of decreased bodily function within a yearuse data from the Osteoarthritis Initiative (OAI)Changes in WC were measured from the intake (0 months) to the follow-up 96 months, and the patients were classified as waist circumference increase group (increase of 5cm) or maintenance group (increase by 5cm)According to the WC at the time of joining the group, the WHO risk category was determined to be large WC (male s 102cm, female s 88cm) or small WC (male 102cm, female 88cm)The result was a decrease in physical function during a 108-month follow-up period (To study the association between 8 year servanda and reduced risk of physical function, the researchers calculated a 95 percent confidence interval of the risk ratio , 95% CI, and adjusted for potential promiscuityRepeated analysis by WHO disease risk classificationthe risk of decreased physical function in the WC increased group was 1.43 times compared to the WC maintenance groupAdults with large baseline WC and increased WC were 1.55 times more likely to experience physical decline than the WC maintenance groupThe risk of a small but increased increase in baseline WC was 1.97 times that of the WC maintenance group (0.84, 4.63)The second year after the increase in WC increases the risk of decreased bodily functionMaintaining WC can reduce the decline in physical function
