Gukura kw'amagufa kugaragara cyane mugihe cy'ubugimbi.Ubu bushakashatsi bwari bugamije gusobanura ingaruka z'umubiri w'ingimbi zubaka n'imbaraga ku bimenyetso by'amagufwa y’amagufwa hamwe no guhinduranya amagufwa kugira ngo bifashe kuzamura imikurire y'amagufwa mu gihe cy'ubugimbi n'ubwangavu no kwirinda ostéoporose.Kuva mu 2009 kugeza 2015, abangavu 277 (abahungu 125 n’abakobwa 152) bafite imyaka 10/11 na 14/15 bitabiriye ubushakashatsi.Ibipimo birimo fitness / indangagaciro z'umubiri (urugero, igipimo cy'imitsi, nibindi), imbaraga zo gufata, ubucucike bw'amagufwa (indangagaciro ya osteosonometry, OSI), hamwe n'ibimenyetso bya metabolism yo mu magufa (fosifata yo mu bwoko bwa alkaline fosifata n'ubwoko bwa I kolagen ihuza N) .peptide ya peptide).Isano nziza hagati yubunini bwumubiri / gufata imbaraga na OSI yabonetse mubakobwa bafite imyaka 10/11.Mu bahungu bafite imyaka 14/15, ingano yumubiri / gufata imbaraga zose zahujwe neza na OSI.Imihindagurikire yimitsi yumubiri yahujwe neza nimpinduka za OSI mubitsina byombi.Uburebure, igipimo cyimitsi yumubiri hamwe no gufata imbaraga kumyaka 10/11 yimyaka mubitsina byombi byari bifitanye isano rya bugufi na OSI (positif) hamwe nibimenyetso byamagufwa ya metabolisme (negative) kumyaka 14/15.Umubiri uhagije nyuma yimyaka 10-11 kumuhungu no kugeza kumyaka 10-11 kumukobwa birashobora kuba ingirakamaro mukwongera ubwinshi bwamagufwa.
Icyizere cy'ubuzima bwiza cyatanzwe n’umuryango w’ubuzima ku isi (OMS) mu 2001 nkigihe kingana nigihe umuntu ashobora kuyobora ubuzima bwiza wenyine mubuzima bwe bwa buri munsi.Mu Buyapani, ikinyuranyo hagati yubuzima buzira umuze nigihe cyo kubaho cyateganijwe kurenza imyaka 10.Niyo mpamvu, “Ihuriro ry’igihugu riharanira guteza imbere ubuzima mu kinyejana cya 21 (Ubuyapani Buzima 21)” ryashyizweho kugira ngo ubuzima bwiza bube3,4.Kugirango ubigereho, birakenewe gutinza abantu igihe cyo kubitaho.Indwara ya syndrome, intege nke na osteoporose5 nimpamvu nyamukuru zo kwivuza mubuyapani.Byongeye kandi, kurwanya syndrome de metabolike, umubyibuho ukabije mu bwana, intege nke na syndrome ya moteri ni ingamba zo gukumira ibikenewe kwitabwaho6.
Nkuko twese tubizi, imyitozo ngororamubiri isanzwe ningirakamaro kubuzima bwiza.Gukina siporo, sisitemu ya moteri, igizwe namagufa, ingingo n'imitsi, igomba kuba nziza.Kubera iyo mpamvu, Ishyirahamwe ry’imyororokere ry’Ubuyapani ryasobanuye “Syndrome de Motion” mu 2007 ko ari “ubudahangarwa bitewe n’indwara zifata imitsi kandi [aho usanga] hari ibyago byinshi byo gusaba ubuvuzi bw'igihe kirekire mu gihe kiri imbere” 7, kandi hakozwe ubushakashatsi ku ngamba zo gukumira kuva icyo gihe.hanyuma.Nyamara, ukurikije impapuro zera 2021, gusaza, kuvunika, hamwe nindwara ya musculoskeletal8 bikomeje kuba impamvu zitera ubuvuzi bukenewe mubuyapani, bingana na kimwe cya kane cyibikenewe byitaweho.
By'umwihariko, bivugwa ko osteoporose itera kuvunika yibasira 7.9% by'abagabo na 22.9% by'abagore barengeje imyaka 40 mu Buyapani9,10.Kumenya hakiri kare no kuvura bigaragara ko aribwo buryo bwingenzi bwo kwirinda ostéoporose.Isuzuma ry'ubucucike bw'amagufwa (BMD) ni ingenzi mu gutahura hakiri kare.Imbaraga ebyiri X-ray yakira (DXA) isanzwe ikoreshwa nkigipimo cyo gusuzuma amagufwa muburyo butandukanye bwa radiologiya.Icyakora, bivugwa ko kuvunika byagaragaye no muri BMD nyinshi, kandi mu 2000 Inama y’igihugu y’ubuzima (NIH) 11 y’ubwumvikane yasabye ko amagufwa yiyongera mu rwego rwo gusuzuma amagufwa.Ariko, gusuzuma ubuziranenge bwamagufwa bikomeje kuba ingorabahizi.
Uburyo bumwe bwo gusuzuma BMD ni ultrasound (ultrasound quantitative, QUS) 12,13,14,15.Ubushakashatsi bwerekanye kandi ko ibisubizo bya QUS na DXA bifitanye isano 16,17,18,19,20,21,22,23,24,25,26,27.Nyamara, QUS ntabwo itera, ntabwo ikoresha radio, kandi irashobora gukoreshwa mugupima abagore batwite nabana.Mubyongeyeho, ifite inyungu isobanutse kurenza DXA, ni ukuvuga ko ikurwaho.
Amagufwa yafashwe na osteoclasts agakorwa na osteoblasts.Ubucucike bw'amagufwa bugumaho niba metabolism igufwa ari ibisanzwe kandi hariho uburinganire hagati yo gufata amagufwa no gukora amagufwa.
Ibinyuranye, metabolism idasanzwe y'amagufwa itera BMD kugabanuka.Kubwibyo, kugirango hamenyekane hakiri kare osteoporose, ibimenyetso byerekana amagufwa ya metabolisme, ibyo bikaba ari ibimenyetso byigenga bifitanye isano na BMD, harimo ibimenyetso byerekana amagufwa no gufata amagufwa, bikoreshwa mugusuzuma metabolism yo mu Buyapani.Ikigeragezo cyo Kuvunika (FIT) gifite aho kirangirira cyo gukumira kuvunika byerekanaga ko BMD ari ikimenyetso cyerekana amagufwa aho kuba amagufwa 16,28.Muri ubu bushakashatsi, hapimwe ibimenyetso byerekana amagufwa yo mu magufa na byo byapimwe kugira ngo bige ku buryo bugaragara imbaraga za metabolism yo mu magufa.Harimo ibimenyetso byerekana amagufwa (ubwoko bwamagufwa ya alkaline fosifata, BAP) nibimenyetso byerekana amagufwa (guhuza N-terminal ubwoko bwa I collagen peptide, NTX).
Ubugimbi nubwangavu bwikura ryikura ryinshi (PHVA), mugihe imikurire yamagufwa yihuta kandi ubwinshi bwamagufwa (impinga yamagufwa, PBM) hashize imyaka 20.
Bumwe mu buryo bwo kwirinda osteoporose ni ukongera PBM.Ariko, kubera ko amakuru arambuye yo guhinduranya amagufwa mu ngimbi atazwi, nta bikorwa byihariye bishobora gutangwa ngo BMD yiyongere.
Kubwibyo, ubu bushakashatsi bwari bugamije gusobanura ingaruka ziterwa numubiri nimbaraga zumubiri kumagufwa yubunini bwamagufwa hamwe nibimenyetso bya skeletale mugihe cyubwangavu, mugihe imikurire yamagufa iba ikora cyane.
Ubu ni imyaka ine yiga cohort kuva mucyiciro cya gatanu cyamashuri abanza kugeza mucyiciro cya gatatu cyamashuri yisumbuye.
