“I’m work­ing on it ... re­ally”

Those un­for­tu­nate peo­ple who suf­fer from a bum knee also may have a se­cret: They may be fib­bing about how much ex­er­cise they’re get­ting. Study re­sults pub­lished on­line by the jour­nal Arthri­tis and Rheuma­tism in­di­cate that a healthy pro­por­tion of pa­tients with os­teoarthri­tis in the knee the amount of phys­i­cal ac­tiv­ity they’re un­der­tak­ing—sig­nif­i­cant be­cause ex­er­cise is ther­a­peu­tic for bones and joints.

The study, led by the North­west­ern Univer­sity Fein­berg School of Medicine, Chicago, re­lied on 1,223 knee os­teoarthri­tis pa­tients ages 45-79 who used ac­celerom­e­ters to al­low for mea­sure­ment of ac­tual phys­i­cal ac­tiv­ity, and found that 12.9% of men and 7.7% of women were meet­ing pub­lic health phys­i­cal ac­tiv­ity guide­lines. That com­pares with pre­vi­ous stud­ies re­ly­ing on— ahem—the pa­tients’ word that in­di­cated that 22% to 40% of adults ages 45 and older with doc­tor-di­ag­nosed arthri­tis met ac­tiv­ity guide­lines.

And the re­sults found that 40% of men and 46% of women in the study were con­sid­ered in­ac­tive, mean­ing they did not have a sin­gle 10minute pe­riod of mod­er­ate-to-vig­or­ous ac­tiv­ity over a one-week pe­riod. “These find­ings point to the ur­gent need for wide­spread dis­sem­i­na­tion of pub­lic health in­ter­ven­tions to re­duce the seden­tary life­style of the 27 mil­lion adults with knee OA,” the au­thors wrote.


Many os­teoarthri­tis pa­tients aren’t ex­er­cis­ing as much as they say.
