Yini i-BMI?
Ukubalwa kwe-BMI kuwuhlelo lokuhlola isisindo, kubhekiselwa engozini yesifo, eyahlongozwa okokuqala isazi saseBelgium u-Adolphe Quelet (1796-1874).
Ngokusebenzisa isixazululo sefomula esidinga amanani amabili aziwayo, ubude nesisindo, ukubalwa kwe-BMI kunikeza i-coefficient ukuze ifakwe kugridi yokuhlola ekhethekile evumela ukuthi ukwazi ukusungula: isisindo esivamile, isisindo esingaphansi, ukukhuluphala nokukhuluphala (okwakamuva, okungenzeka ihlukaniswe ngamazinga ahlukene obunzima).

Isetshenziselwa ini i-BMI?
Selokhu yasungulwa, i-BMI iye yaba ithuluzi lokuxilonga elihamba phambili lokuhlola isisindo somuntu kanye nesikhundla esihlobene nesejwayelekile - ngokwezibalo ezihlotshaniswa nengozi ephansi yokugula ngezifo ze-metabolic nokunye.

Kodwa-ke, ngenxa yokunemba okungalungile (akunaki usayizi wohlaka lwamathambo kanye nemisipha) kanye nemikhawulo yohlelo lokusebenza ehlanganisayo (akufanele isetshenziselwe ukuhlolwa kwezingane nabasubathi abasezingeni eliphezulu), namuhla i-BMI elula ithathelwa indawo ngokwengxenye. .ngezindlela zokulinganisa ezinembe kakhudlwana nezintsha, kodwa ezingasebenzi neze.

Amanani afaneleka kakhulu e-BMI, uma kubhekiselwa kusici se-metabolic-health, acishe abe ngu-21-22 (22.5 kg/m2 emadodeni nama-21 kg/m2 kwabesifazane). Kodwa-ke, ocwaningweni olulodwa, amadoda aseBrithani akhangwa kakhulu kumamodeli wesifazane ane-BMI ye-20.85; leli nani, elingenakho ukubaluleka kokubikezela engcupheni ehambisana ne-pathologies ye-metabolic kanye nezinkinga ezihlukahlukene, esikhundleni salokho linikeza isifinyezo sesilinganiso esilindelwe ngokwemibandela "yesisindo esikahle" - funda izihloko ezinikezelwe esithombeni somzimba kanye nokuphazamiseka kokuziphatha kokudla (DCA).

Ibanga elijwayelekile le-BMI (18.5-24.9 kg/m2) libanzi ngokunembile njengomsebenzi womehluko ophathekayo ohlobene nesakhiwo somzimba sabantu. Njengoba kulindelekile, ukubalwa kwe-BMI akunaki isisindo somzimba (isibonelo, esikhulu, emadodeni nasebancane kunabesifazane nabadala), kungasaphathwa umehluko ophathelene nesisindo samathambo kanye nenani phakathi kobude bezitho nemilenze. kanye nesiqu.

Abesilisa Nabesifazane
I-BMI yabesilisa nabesifazane
Abaningi baphikisa ngokuthi i-BMI kufanele icabangele ubulili, okungukuthi ihlukile phakathi kwabesilisa nabesifazane. Empeleni kuwukungaqondile, ngoba okwenza umehluko izici ezivame ukuxhunyaniswa nakho, kodwa hhayi ngendlela eqondile neqondile.

I-BMI ayicabangi izici ezifana nobukhulu besisindo somzimba, uhlaka lwamathambo kanye namafutha abalulekile. Kuyaziwa ukuthi amadoda anesilinganiso esiphezulu se-musculature nesakhiwo samathambo kunabesifazane, ukuthi asebekhulile babuthakathaka kunentsha, nokuthi abesifazane banamaphesenti aphezulu amafutha abalulekile adingekayo ekusebenzeni kokuzala. Ngokuphathelene namathambo, kungenzeka ukuhlanganisa ukubala kwe-BMI ngezibalo ezihlanganisayo ezivumela ukulinganisa lokhu okuguquguqukayo futhi.

Lokhu akusho ukuthi kukhona abesifazane kanye nabantu asebekhulile abanamavolumu aphezulu emisipha namafutha aphansi kunamadoda amaningi kanye nentsha. Yingakho ukuhlolwa kwe-BMI akufanele kusetshenziselwe ukulinganisa isisindo somuntu ngokunembe kakhulu nangokunembile, kodwa ukuze kubonakale inkomba yobungozi ehambisana nokukhuluphala kanye nokungaphansi kwesisindo somzimba.
