Suʻega o le mineral density

O le ponaivi o le mineral density (BMD) e faʻataʻitaʻia ai le aofaʻi o le kalama ma isi ituaiga o minerale o loʻo i se vaega o lou ponaivi.

Ole faʻataʻitaʻiga lenei e fesoasoani i lau soifua maloloina tausi maʻi ia iloa le osteoporosis ma valoia lou aʻafiaga mo ponaivi gaui.

E tele auala e faia ai suʻesuʻega o ponaivi.

O le auala sili ona taatele ma sao e faʻaaogaina ai le scanner e lua-malosi x-ray (DEXA). E faʻaaoga e le DEXA le laʻasaga maualalo ile x-ray. (E te maua sili radiation mai le fataata x-ray.)

E lua ituaiga o DEXA scans:

• Tutotonu DEXA - Oe taoto luga o se laulau vaivai. E pasia e le scanner lou pito i lalo ma lou suilapalapa. I le tele o tulaga, oe le tau manaʻomia lavalava. O lenei faʻataʻitaʻi o le sili lea o suʻega e valoia ai lou lamatiaga mo malepe, aemaise lava o lou suilapalapa.
• Peripheral DEXA (p-DEXA) - O nei tamai masini fuaina le ponaivi density i lou tapulima, tamailima, vae, poʻo le mulivae. O nei masini o loʻo i ofisa o le soifua maloloina, fale talavai, fale faʻatau, ma i faleoloa faʻasoifua maloloina.

Afai oe ma pe mafai ona maʻito, taʻu i lau tautua aʻo leʻi faia lenei suʻega.

AUA le aveina ni vailaʻau kalama mo le 24 itula ae leʻi faia le suʻega.

O le a taʻu atu ia te oe e aveʻese uma uʻamea mea mai lou tino, pei o teuteuga ma faʻamau.

O le scan e leai se tiga. Oe manaʻomia le filemu i le taimi o le suʻega.

Bone mineral density (BMD) o faʻataʻitaʻiga e faʻaaogaina e:

• Faʻamaonia leiloa o ponaivi ma le osteoporosis
• Vaʻai pe faʻafefea ona galue lelei vailaʻau osteoporosis
• Valoia lau lamatiaga mo le gaʻo ponaivi i le lumanaʻi

O le faʻataʻitaʻiga ole ponaivi e fautuaina mo tamaʻitaʻi uma e 65 tausaga ma sili atu.

E leai se maliega atoa pe tatau ona faia e aliʻi lenei ituaiga suʻega. O nisi kulupu fautuaina le suʻesuʻeina o tamaloloa i le 70 tausaga, ae o isi o loʻo taua e le lava le faʻamaoniga e fai mai pe o aliʻi i lenei tausaga penefiti mai le suʻesuʻega.

Tamaʻitaʻi talavou, faʻapea foʻi ma aliʻi o soʻo se tausaga, ono manaʻomia foʻi le faʻamaonia o le ponaivi o ponaivi pe a fai e iai ni aʻafiaga o le osteoporosis. O nei tulaga lamatia aofia ai:

• Fracturing se ponaivi ina ua mavae le 50 tausaga
• Malosiaga aiga talaʻaga o le osteoporosis
• Talaʻaga o togafitiga mo le kanesa prostate poʻo le kanesa o le susu
• Talaʻaga o faʻafomaʻi pei o rheumatoid gugu, maʻi suka, le paleni o lou toto, poʻo le anorexia nervosa
• Vaiaso vave (pe mai mafuaʻaga masani poʻo le hysterectomy)
• Faʻaaoga umi o vailaʻau pei o le corticosteroids, thyroid hormone, poʻo le aromatase inhibitors
• Paʻu maualalo o le tino (laʻititi ifo i le 127 pauna) poʻo le maualalo o le tino vaega faʻatulagaina (lalo ifo o le 21)
• Taua leiloa o le maualuga
• Tapaa i se taimi umi poʻo le soʻona inu 'ava malosi

O iʻuga o lau suʻega e masani ona lipotia o se togi-T ma le Z-togi:

• T-score faʻatusatusa lou ponaivi density ma lena o se soifua maloloina tamaitai talavou.
• Z-score faʻatusatusa lou ponaivi density ma isi o isi tagata o lau tausaga, itupa, ma tuʻuga.

Faʻatasi ma togi uma, o le le lelei numera o lona uiga oe i ai manifinifi ponaivi nai lo averesi. O le tele faʻaletonu o le numera, o le maualuga lou tulaga lamatia mo se ponaivi gaui.

O le T-togi e i totonu o le tulaga masani pe a fai o le -1.0 pe o luga atu.

O le suʻesuʻe o le ponaivi o ponaivi e le suʻesuʻeina gau. Faʻatasi ai ma isi tulaga lamatiaga oe ono i ai, e fesoasoani e valoia lou tulaga lamatia mo le i ai o le ponaivi gaui i le lumanaʻi. O lau tautua o le a fesoasoani ia te oe ia malamalama i faʻaiuga.

Afai o lau T-togi o le:

• I le va -1 ma le -2.5, oe ono maua vave ivi leiloa (osteopenia)
• Lalo -2.5, oe ono maua i le osteoporosis

Fautuaina togafitiga e faalagolago i lau aofaʻi gaui tulaga lamatia. Lenei lamatiaga mafai faʻatatauina faʻaaogaina le FRAX togi. E mafai e lau tautua ona faʻamatala atili atu ia te oe lenei mea. E mafai foʻi ona e mauaina faʻamatalaga e uiga i le FRAX i luga ole laiga.

O le malosiʻaga o ponaivi o loʻo faʻaaogaina ai sina vaega o leisa. Tele o tagata atamamai lagona o le lamatiaga e matua maualalo pe a faatusatusa i aoga o le sailia osteoporosis ae e te leʻi gagauina se ponaivi.
