Kugadzirisa kukakavara kwechangobva kuitika pamusoro pezviyero zveBMI
Ari kunyanya kuwandisa - kuva neBII yakakosha-yakabatana nehuwandu hwehutano hwehutano, kana handizvo here? Nepo kuwedzera kuneta kunowedzera zvakajeka kunowedzera dambudziko rehutano, uye apo hurumende uye nyanzvi dzezvokurapa munguva pfupi yapfuura dzakanyanyisa kusimbisa kuchengetedza "chimiro" chemuviri wepanyama, ngozi yakawandisa inokonzerwa nokuva kunyanya kuwandisa (kusingapesana nezvakawanda) haisi pachena.
Chii Chinonzi Studies Studies?
Izvo zvisinganzwisisiki zvemubvunzo uyu mupfupi zvakapinda mumaonero makore mashomanana akapfuura apo imwe nyaya inowanikwa muLancet yakaratidza kuti varwere vemwoyo vakange vari "zvishoma" kudarika, maererano neBMI (muviri wehuwandu hwemadziro), chaizvoizvo vakanga vane ngozi shoma shoma kupfuura varwere vakanga vari "zvakaenzana" kuyerwa.
Kunyangwe vanyori vepa pepa inoita sevanonyadziswa zvishoma nezvakawanikwa izvi. Uye kukanganisa nyaya yacho inowedzera, nyaya mbiri huru dzinoonekwa panguva imwechete muNew England Journal yemishonga yakatsigira pfungwa yakakurumbira-yokuti kunyanya kudarika, neyakawanda, kunowedzera dambudziko rekufa.
Kuedza kukonzera kuvhiringidzika kwevanhu pamusoro penyaya iyi, maererano neWall Street Journal , Centers for Disease Control yakaraira vatsvakurudzi vayo kuti vasataure pachena pamusoro pezvidzidzo zvitsva, uye "mutauriri wehurumende yaisina kutaura zvakare." (Unogona kuverenga nyaya yeWall Street Journal apa, asi inoda kubhadhara.)
Nhamba ye BMI inofanirwa kuva nzira yekukurumidza kuziva kana munhu ane mafuta akawanda. BMI zvikamu makumi maviri kubva ku20 kusvika ku24.9 zvinoonekwa sezvakanaka, zvikamu zve25 kusvika ku29.9 zvakanyanya kudarika, makumi matatu kubva ku30 kusvika ku 34.9 zvakanyanya, uye zvikamu zvinopfuura makumi matatu zvakapfuura zvakanyanya. Zvikamu zvinopfuura makumi maviri zvinotaridzirwa pasi pehutera. Iwe unogona nyore nyore kuverenga chikoro chako uchishandisa iyi calculator.
Zvinenge zvese zvidzidzo zvinoshandisa BMI zvibvumirano zvakabvumirana pane zvishoma. Chokutanga, vanhu vakaoma kana kuti vanorema zvikuru vane ngozi yakawanda yehutano hwepfungwa uye rufu. Chechipiri, vanhu vane uremu hune humwewo vane ngozi yakawanda yekufa . (Iyi inofungidzirwa kuti inonyanya kuitika nekuda kwechirwere chetachiona - sechirwere chepfungwa, chirwere chemapapu , kenza kana utachiona - izvo zvinowanzokonzera kurasikirwa kwechiremera sezvo chirwere chinopfuurira.)
Kana pane nharo inotarisana nevanhu vanonzi vakawandisa, asi kwete kuwedzera, ndiko kuti, avo vana BMI vanoverengeka vari zvishoma kupfuura 25. Zviongorori zvakawanda zvakaratidza kuwedzerwa kwehutano hwehutano kunyange nokuda kwechimiro chekuwedzera kwehuwandu. Asi zvidzidzo zvishomanana zvinoratidza pangozi shoma yevanhu ava.
Tsanangudzo dzakasiyana-siyana dzechiratidzo ichi chinokanganiswa dzakataurwa, asi iyo inonyanya kushandiswa ndiyo pfungwa yokuti BMI chiyero pachayo-iyo inongorangarira uremu hwomunhu uye kukwirira - kazhinji inopa chiyero chenhema che "kuwandisa" kana munhu ari zvinongova zvakanaka uye zvine musimba wakanaka. Izvi zvinoreva kuti kune vanhu vane utano hwakanaka neBMIs ye 25 kana 26, "kuwandisa" kurema kunogona kunge kusina mafuta.
Closing Thoughts
Kuva nemafuta akawanda-kunyanya, mafuta akawanda muimba yepamuviri - anonyanya kukoshesa kushushikana kwepfungwa mumwoyo yehutano uye inowedzera ngozi yehutano hwehutano .
Nhamba yeBMI yakanyatsonaka kune vanhu vane uwandu hwakanyanya kana kuwandisa kwazvo (semuenzaniso, zvakaoma kwazvo kuisa zvakakwana musimba kuti uwane BMI yako kupfuura makumi matatu usingashandisi steroids), asi BMI haisi yakarurama yekucherechedza vanhu vari "overweight." Iko kune, zvechokwadi, vamwe vanhu vane BMI vanoverengeka mumakore 25 kusvika ku 29 nekuda kwekuti vari mumamiriro makuru. Asi, ini ndinozviisa pasi, ivo vanhu vanogona kunge vanoziva kuti ivo vanaani.
Saka, kana iwe uine chikamu cheBMI mu "uwandu", uye uri kufunga nezvekupembererwa nekuti iwe unosarudza kutenda nyaya yeLancet uye kusava nehumwe humwe humwe uchapupu hunopesana, ngatitongere iwe upindure mubvunzo mumwe chete usati wapera icho chinotevera Bud: Chiuno chako chakakura zvishoma kudarika chiuno chako chechiuno here?
Kana "hongu," iwe unogona kunge uri mumwe wevanhu ivavo vakanyatsogadzikana, uye "kuwedzera" kuwedzera kunokonzera ma BMI mapuropa, uye kwete mafuta (mumamiriro ezvinhu akadaro iwewo hauna kugadzirira kupemberera nokudya zvisina chinhu makoriyori). Asi kana mhinduro yacho ichiti "kwete," uye iwe unotya zvakanyanya-mafuta akaiswa, hauna chaunopemberera pamusoro.
Nokuti, nepo huwandu hweBMI dzimwe nguva hunobatsira uye huri nyore kuverenga, chiuno-kusvika-hip chiyero ndicho chinonyanya kukosha yehutano hwemwoyo .
