Iimpawu zanamhlanje kwimveliso yefashini ziya kutshintsha ekuhloneleni iifom zeRubensian ezintle, nangona ubomi bemihla ngemihla bethandwa ngabantombazana abancinci. Kodwa, njengoko besithi, akukho mpikiswano malunga nokuthanda, kukho abathandi besifazane abahlukeneyo. Nangona kunjalo, enye yeengxaki ezixoxwa ngazo zihlala zikulwa nokulwa nokunyuka komzimba. Ukongezelela, ngenxa yesigxina sobomi, abafazi abaninzi abanalo ixesha lokuzijonga kwaye esikhundleni sezemidlalo basebenzisa iintlobo zezidlo. Kwaye nantsi unokwazi ukuhlangabezana nesinye inkathazo, sele sele uhlukile: i-anorexia. Emva kwakho konke, amantombazana amaninzi, ezama ukulinganisa lo mfanekiso kwiifom zeendlela eziqhelekileyo, nje ngokuzikhupha. Ngako oko, ukuze ungadluli kwaye uqonde ngokucacileyo ukuba ufuna ukunyusa okanye ukulahla, kukho into efana nenqwelomba yomzimba, into elula kakhulu.
I-index ye-mass body index, okanye i-BMI, inceda ukucacisa ngokuthe ngqo ukuba ubude bomntu nobungakanani bomntu buhambelana njani. Le nkcazo yaveliswa emva kwe-1869 yenzululwazi yenzululwazi kunye no-Adolf Ketle (eBelgium), ngoko ke ubizwa ngokuba yi-Quetelet index. Ukuze uzimisele ukubeka ubungakanani bomzimba womzimba, uya kubala i-index body mass, ifom ekwahlula isisindo somfazi ekuphakameni kwayo kwiimitha, ububanzi. Oko kukuthi, isibalo sobunzima bomzimba kubasetyhini = ubunzima / ukuphakama2.
Ngokomzekelo, intombazana inesisindo esingama-65 kg, kwaye ubude bayo buyi-168 cm. Okokuqala, kuyimfuneko ukudlulisela ukukhula ukusuka kumitha ukuya kumitha: 168 cm = 1.68 m. Ngoku sifuna ukuphakamisa lesi sibalo kumandla obala: 1.68 m * 1.68 m = 2.8224 m2. Ukwazi i-formula apho isibalo sabantu besibalo samabhinqa sibalwa, sinqumle: 65 kg / 2.8224 m2 = 23.03.
Itheyibhile yesalathisi somzimba
Isigaba sokuqala ekubalweni kweBMI yabasetyhini kugqityiwe. Kwaye ukwenzela ukuba inani elibangela ukuba linokubaluleka, i-BMI itafile yaphuhliswa. Ngokusekelwe kwiingcebiso ze-World Health Organisation, ukulingana komzimba kunye nokukhula kwayo, kubalwa ngokwe-BMI yabasetyhini, kufuneka kuthathe oku kulandelayo:
- Inkcazo yomzimba wabasetyhini i-16 okanye ngaphantsi - umntu unelungelo lokulahleka komzimba;
- 16-18 - ubunzima bomzimba obaneleyo;
- 18-25 - isalathisi somzimba ngokuqhelekileyo;
- 25-30 - ubunzima bomzimba obuninzi;
- 30-35 - ukukhuluphala kwesidanga sokuqala;
- 35-40 - ukukhuluphala kwesidanga sesibini;
- 40 nangaphezulu yinkcazo yesininzi somzimba yabasetyhini abanesisindo sezinga lesithathu.
Kufuneka kuqondwe ukuba, ukwazi indlela yokumisela i-BMI, akunakwenzeka ukufumana ngokuchanekileyo ukuba ulahlekelwa isisindo okanye hayi, ekubeni le ncwadana inxulumene kwaye ayiqwalasele inani elikhulu lezinto. Ngoko ke, isalathisi somzimba womzimba, esiqhelekileyo ekukwabelweni kwakhona kwe-18-25, sinokufana nomntu opheleleyo kunye nomntu ochaphazelekayo kwimidlalo. Ukongeza, kufuneka uqwalasele iminyaka. Umfazi ofanayo owakheka njengentombazana ekhukhulayo inokulinganisela ngakumbi ngenxa ethile
Isalathisi sobunzima besibalo sokukhulelwa
Intsholongwane enomdla kukuba ezinye izazinzulu ziqinisekile ukuba umntwana onomzali omncinci, amathuba okuba lukhuni luphezulu kunelobanye abantwana. Ngoko ke, kubalulekile ukubala i-BMI ekukhulelwe okanye ukucwangcisa umntwana. Inkcazo ye-BMI yabasetyhini abakhulelweyo banceda ekufumaneni ukuba bunzima bunjani umfazi onokufumana kwiinyanga ezili-9. I-BMI eneminyaka engama-20, oogqirha bancomela ukuba bafumane i-13-16 kg ngexesha lokukhulelwa, ukuba ubunzima bomzimba buncinci ngexesha lokukhulelwa kwaba ngu-20-27, ngoko ngeli xesha le nto ibhinqa i-10-14 kg, i-BMI ingaphezu kwe-27, inzuzo yesisindo kufuneka ibe . Kodwa, ekubeni kwindawo ekhangayo, kufuneka uqaphele ngokulinganisa ubunzima: ngexesha lokukhulelwa, akufanele lilahlwe.
