Nyamakazi ya m’mabondo yachulukanso kuwirikiza kawiri kuyambira pakati pa zaka za m’ma 1900

Matenda a mafupa a m’mabondo ndi ofala kwambiri, omwe amalepheretsa matenda a mafupa omwe ali ndi zifukwa zomwe sizimveka bwino koma nthawi zambiri zimayambitsidwa ndi ukalamba ndi kunenepa kwambiri.Kuti tidziwe bwino za etiology ya osteoarthritis ya bondo, kafukufukuyu akuwonetsa momwe matendawa amakhalira nthawi yayitali ku United States pogwiritsa ntchito zitsanzo zazikulu za chigoba kuyambira nthawi zakale mpaka pano.Timasonyeza kuti nyamakazi ya m’mawondo inalipo nthawi yaitali, koma kuyambira chapakati pa zaka za m’ma 1900, matendawa achulukanso kuwirikiza kawiri.Kufufuza kwathu kumatsutsana ndi lingaliro lakuti kuvulala kwaposachedwa kwa nyamakazi ya bondo kunachitika chifukwa chakuti anthu amakhala ndi moyo wautali komanso amakhala onenepa kwambiri.M'malo mwake, zotsatira zathu zikuwonetsa kufunikira kophunzira zowonjezera, zomwe zingapeweke zomwe zakhala zikuchulukirachulukira mkati mwa theka lapitalo.

Knee osteoarthritis (OA) imakhulupirira kuti ikufala kwambiri masiku ano chifukwa cha kuwonjezeka kwaposachedwa kwa nthawi ya moyo ndi index mass index (BMI), koma kulingalira kumeneku sikunayesedwe pogwiritsa ntchito mbiri yakale kapena yachisinthiko.Tinasanthula zochitika za nthawi yayitali mu kufalikira kwa maondo a OA ku United States pogwiritsa ntchito mafupa opangidwa ndi cadaver a zaka ≥50 y omwe BMI yawo pa imfa inalembedwa komanso omwe anakhalapo nthawi ya mafakitale oyambirira (1800s mpaka oyambirira 1900s;n= 1,581) ndi nyengo yamakono ya postindustrial (mochedwa 1900s mpaka oyambirira 2000s;n= Pa 819).Knee OA pakati pa anthu omwe akuganiza kuti ali ndi zaka ≥50 y adawunikidwanso m'mafupa opangidwa ndi archeologically a osaka zakale komanso alimi oyambirira (6000-300 BP;n= 176.OA adapezeka potengera kukhalapo kwa kutupa (polish kuchokera kukhudzana ndi fupa-pafupa).Ponseponse, kufalikira kwa maondo a OA kunapezeka kuti ndi 16% pakati pa zitsanzo za postindustrial koma 6% ndi 8% yokha pakati pa zitsanzo zoyambirira za mafakitale ndi mbiri yakale, motero.Pambuyo polamulira zaka, BMI, ndi zosiyana zina, kufalikira kwa maondo a OA kunali 2.1-fold high (95% nthawi yodalirika, 1.5-3.1) mu chitsanzo cha postindustrial kusiyana ndi chitsanzo choyambirira cha mafakitale.Zotsatira zathu zikuwonetsa kuti kuwonjezeka kwa moyo wautali ndi BMI sikukwanira kufotokozera pafupifupi kuwirikiza kawiri kwa mawondo OA omwe achitika ku United States kuyambira pakati pa zaka za zana la 20.Knee OA ndiyotheka kupewedwa kuposa momwe amaganizira, koma kupewa kudzafunika kufufuza paziwopsezo zina zodziyimira pawokha zomwe zidayamba kapena zachulukidwa pambuyo pa mafakitale.
