Izindinganiso zanamuhla embonini yezemfashini ziyashintsha ekukhulekeleni amafomu amahle akwaRubensian, nakuba empilweni yansuku zonke amadoda asakhangwa namantombazane amancane. Kodwa, njengoba bekusho, akukho mpikiswano mayelana nokuthanda, kukhona abathandi besifazane bezingoma ezahlukene. Noma kunjalo, enye yezinkinga ezikhulunywe kakhulu isalokhu isilwa nesisindo somzimba esiningi ngokweqile. Ngaphezu kwalokho, ngenxa yesigqi sokuphila, abesifazane abaningi abanaso isikhathi sokuzibuka futhi esikhundleni sezemidlalo basebenzisa izidlo ezihlukahlukene. Futhi lapha ungase uhlangabezane nenye inkinga, kakade yinto ehlukile: i-anorexia. Emva kwakho konke, amantombazane amaningi, ezama ukulinganisa lesi sibalo emafomethi amafomethi ejwayelekile, nje ukuzikhukhumeza ngokwabo. Ngakho-ke, ukuze ungahambi ngokweqile futhi uqonde ngokucacile ukuthi udinga ukuthatha isisindo noma ukulahla, kukhona into enjengokukhomba kwenqwaba yomzimba, indlela elula kakhulu.
I-index ekahle yomzimba, noma i-BMI, isiza ekunqumeni ngokungaqondile ukuthi ukuphakama nesisindo somuntu sihambisana kanjani. Le nkomba yasungulwa emuva ngo-1869 yi-sociologist kanye nesazi sezibalo u-Adolf Ketle (eBelgium), ngakho-ke ubizwa nangokuthi inkomba ye-Quetelet. Ukuze ubone ukuthi yisiphi isisindo somzimba esizokwenza sibe ngcono, ungakwazi ukubala inkomba yomzimba womzimba, ifomula yokuhlukanisa isisindo sowesifazane ekuphakameni kwakhe ngamamitha, isikwele. Okusho ukuthi, inkomba yomzimba womzimba yabesifazane = isisindo / ukuphakama.
Isibonelo, intombazane inesisindo esingama-65 kg, futhi ukuphakama kwayo kuyi-168 cm. Indlela yokunquma inkomba yomzimba wayo? Okokuqala, kuyadingeka ukudlulisa ukukhula kusuka kumamitha kuya kumamitha: 168 cm = 1.68 m. Manje sidinga ukuphakamisa lesi sibalo kumandla wesigcawu: 1.68 m * 1.68 m = 2.8224 m2. Ukwazi ifomu lapho kubalwa khona inani lomzimba womzimba wabesifazane, siyinquma: 65 kg / 2.8224 m2 = 23.03.
Ithebula lenkomba yomzimba womzimba
Isigaba sokuqala ekubalweni kwe-BMI yabesifazane sesiphelile. Futhi ukuze inombolo enomphumela ibaluleke kakhulu, ithebula le-BMI lakhiwa. Ngokusekelwe ezinconyweni ze-World Health Organization, ukulingana kwesisindo somzimba nokukhula kwayo, kubalwa ngokwe-BMI yabesifazane, kufanele kusho okulandelayo:
- Inkomba yomzimba womzimba yabesifazane ineminyaka eyi-16 noma engaphansi - lowo muntu unesisindo esikhulu somzimba;
- 16-18 - isisindo somzimba esanele;
- 18-25 - inkomba evamile yomzimba;
- 25-30 - isisindo somzimba ngokweqile;
- 30-35 - ukukhuluphala kwezinga lokuqala;
- 35-40 - ukukhuluphala kwezinga lesibili;
- 40 nangaphezulu yi-index yesisindo somzimba yabesifazane abanokukhuluphala kwesilinganiso sesithathu.
Kumele kucatshangwe ukuthi, ukwazi ukuthi kunjani ukucacisa i-BMI, akunakwenzeka ukuthola ukuthi nokho ukulahlekelwa isisindo noma cha, njengoba lesi sibonakaliso sinesihlobo futhi singacabangi inombolo enkulu yezici. Ngakho-ke, inkomba yomzimba womzimba, evamile kuwo ukubuyiswa kwe-18-25, ingafana nomuntu ophelele nomuntu ohlanganyela ezemidlalo. Ngaphezu kwalokho, udinga ukucabangela ubudala. Owesifazane ofanayo owakheka njengendodakazi ekhulayo angase abe nesisindo esingaphezulu ngenxa yokuthi
Inkomba yomzimba womzimba wokukhulelwa
Iqiniso elithakazelisayo ukuthi abanye ososayensi bayaqiniseka ukuthi ingane enezingane ezinomzimba omncane, amathuba okuba i-skinny iphakeme kuneyezinye izingane. Ngakho-ke, kubalulekile ukubala i-BMI ekukhulelwe noma ukuhlela ingane. Incazelo ye-BMI yabesifazane abakhulelwe iyasiza ukuthola ukuthi isisindo esingakanani owesifazane angasithola ezinyangeni ezingu-9. Njengoba i-BMI eneminyaka engama-20, odokotela batusa ukuba bathole u-13-16 kg ngesikhathi sokukhulelwa, uma inkomba yomzimba wesikhumba ngesikhathi sokukhulelwa yayingu-20-27, ngakho-ke ngalesi sikhathi owesifazane udinga u-10-14 kg, ene-BMI engaphezu kuka-27, inzuzo yesisindo kufanele ibe ngaphansi . Kodwa, njengoba usesimweni esithakazelisayo, udinga ukuqapha ngezivivinyo ngesisindo: ngesikhathi sokukhulelwa, akufanele kulahlwe.
