Malunga nale Calculator
A waist-to-height ratio (WHtR) calculator divides your waist circumference by your height. The simple public-health rule is to "keep your waist to less than half your height", so a ratio under 0.5 is the healthy target for most adults. Research suggests WHtR predicts cardiometabolic risk at least as well as BMI while being easy to measure.
The calculation is waist ÷ height in the same units. An 85 cm waist and 175 cm height give 85 ÷ 175 = 0.49, just inside the healthy range, and the tool reports a healthy maximum waist of 87.5 cm (half of 175). Ratios of 0.5–0.6 indicate increased risk and above 0.6 high risk. The single 0.5 threshold applies across most ages and both sexes, which makes the screen easy to remember.
Use WHtR as a quick check of central (abdominal) fat, the kind most linked to heart and metabolic disease. It needs only one circumference plus your height and, unlike waist-to-hip ratio, does not require a hip measurement. Measure the waist midway between the lowest rib and the top of the hip bone. It is a screening guide, not a medical diagnosis.
Imibuzo ebuza rhoqo
Yintoni uthelekiso olufanelekileyo phakathi komphakamo kunye nobude?
Ixabiso elingaphantsi kwe-0.5 lisetyenziswa ngokubanzi njengexabiso elifanelekileyo lokuyeka ukutshatyalaliswa kwempilo—imilenze yakho kufuneka ibe ngaphantsi kwengxenye yobude bakho. Ixabiso elingaphantsi kwe-0.5-0.6 libonisa ukuba kukho umngcipheko ophezulu kwaye elingaphezulu kwe-0.6 libonisa ukuba kukho umngcipheko ophezulu.
IWHtR ithelekiswa njani neBMI?
I-WHtR ilinganisela ngokuthe ngqo i-fat ephakathi, eyona nto ingozi kakhulu, kwaye isebenzisa inqanaba elifanayo le-0.5 phakathi kweeminyaka kunye nodidi lwesini. Iinkqubo ezininzi zophando zifumanisa ukuba ibonisa umngcipheko wenhliziyo kunye nemetabolism njenge-BMI okanye ingcono.
Ingaba kufuneka ndibe nesisindo esingakanani sobude bemilenze yam?
Gcina umlenze wakho ngaphantsi kwengxenye yobude bakho. Kwi-175 cm oku kuthetha umlenze ngaphantsi kwe-87.5 cm (i-34.5 in); isixhobo sibonisa oku kuphezulu okulungileyo kobude obungenayo.
Ingaba ubungakanani bemilenze nobude busebenza kubantu bonke?
Umgangatho we-0.5 usebenza kubantwana abakhulu nabantwana abancinci, nokuba baneminyaka ephindwe kabini okanye i-100% ye-BMI, kwaye usebenza kubantwana abancinci nabantwana abancinci.
Ndiyivavanya njani intamo yam ukuze ndiyisebenzise kwi-WHtR?
Uvavanyo luya kwenziwa kwindawo ephakathi phakathi kwethambo eliphantsi kunye nenqanaba eliphezulu lethambo le-hip (i-navel), ngetheyiphu ephakamileyo kwaye ikhuseleke emva komoya oqhelekileyo ophumayo. Sebenzisa iyunithi efanayo ye-waist kunye nobude ukuze uthelekiso lube lungile.
Ingaba i-WHtR okanye uthelekiso lwesifuba nesifuba lungcono?
I-WHtR ifuna kuphela ubukhulu becala kunye nobude kwaye isebenzisa i-0.5 ye-cut-off, ngelixa i-WHR ithelekiswa nobude bengalo kunye ne-hips; abaphandi abaninzi bakhetha i-WHtR ngenxa yobulula bayo.
