Nyanzvi dzinoramba dzichiitisana nharo nezve chiitiko chemuviri. Zvinoenderana neyakajairwa maitiro, zana nemakumi mashanu emaminetsi ekuenzanisira kurovedza muviri pasvondo ndiyo yakakwana huwandu hwekurovedza muviri kusimudzira uye kuchengetedza hutano. Nekudaro, hazvisi pachena kana huwandu hwakakurudzirwa ndicho chidiki chinodiwa kune wese munhu - kana kana iri iwo huwandu hwakaringana hwekutakura. Masayendisiti zvakare aisaziva kana paine muganho wepamusoro pamitoro inopfuura iyo mhedzisiro inogona kuve nenjodzi; uye kana kumwe kurovedza muviri (kunyanya maererano nesimba) kungave kunonyanya kushanda kune hutano uye kuwedzera hupenyu kupfuura kumwe.
Zvidzidzo zviviri zvinonakidza zvitsva zvakaburitswa svondo rapfuura muJAMA Yemukati Mushonga zvinounza kujekesa kumubvunzo uyu. Kubva pamhedzisiro yavo, masayendisiti akagumisa kuti huwandu hwakaringana hwekurovedza muviri hwakati pfuurei kupfuura vamwe vedu nhasi, asi zvishoma pane vazhinji vedu tingatarisira. Uye kurovedza muviri kwenguva refu kana kwakasimba hakugone kukuvadza hutano; pane kudaro, ivo vanogona kutowedzera makore kuhupenyu hwako.
Masayendisiti kubva kuU.S. National Cancer Institute, Harvard University, nemamwe masangano vakaunganidza uye vakaunganidza dhata pane zviitiko zvemuviri zvevanhu kubva kumatanhatu makuru eongororo yezvehutano. Ruzivo rwakatorwa kubva kune vanopfuura zviuru mazana matanhatu negumi nezvisere zvevakuru vepakati rakagadziriswa.
Uchishandisa iyi data, vaongorori vakapatsanura vanhu vakuru neyakawandisa nguva yakashandiswa pakudzidziswa kwevhiki nevhiki, kubva kune avo vasina kurovedza muviri zvachose kune avo vakashandisa kagumi zvakapetwa zvishoma (kureva, vakapedza maawa makumi maviri nemashanu ezviitwa zvine mwero pavhiki kana kupfuura ). ).
Ivo vakabva vaenzanisa makore gumi nemana manhamba ehuwandu hwevakafa muboka rega rega. Izvi ndizvo zvavakawana.
- Zvakazoitika, uye hazvishamise, kuti pakati pevanhu vasingatambe zvemitambo zvachose, njodzi yekufa kwekutanga yakanyanya.
- Panguva imwecheteyo, kunyangwe pakati peavo vakashandisa zvishoma, njodzi yekufa nguva isati yakwana yakadzikira ne20%.
- Vaya vakatevera nhungamiro padyo nemaminetsi zana nemakumi mashanu ekurovedza muviri zvine mwero pavhiki vakararama kwenguva yakareba, uye pamusoro pemakore gumi nemana, iri boka rakange riine 150% vashoma kufa pane iro risingashandise boka.
- Misiyano inonyanya kukosha yakaonekwa pakati peavo vakapfuura nhanho yakakurudzirwa yekurovedza muviri katatu, kurovedza zvine mwero, kunyanya kufamba uye kumhanya, kwemaminetsi mazana mana nemakumi mashanu pasvondo, kana zvishoma kudarika awa pazuva. Kune vanhu ava, njodzi yekufa nguva isati yakwana yaive 450% yakaderera pane kune avo vaisashanda uye vasina kumbobata muviri zvachose, uye panguva ino rubatsiro rwehutano rwunosvika pamuganhu wavo wakanyanya.
- Vanhu vashoma vanoshandisa zvakapetwa kagumi chiyero chakakurudzirwa vane zvakadzikira zvakafanana panjodzi yekufa nguva isati yakwana sezvinoita vanhu vanongoteedzera nhungamiro. Maawa ekuwedzera avanopika vangadikitira mujimu haaiti kuti hupenyu hwavo hurebe. Asi ivo havawedzere njodzi yekufa vadiki.
