Ucwaningo lubonisa ukuxhuma phakathi kwamazinga we-Race and Cholesterol
Akekho uhlanga noma ubuhlanga obunamandla ekuthuthukiseni amazinga aphezulu e-cholesterol kodwa ezinye izifundo zikhomba ukuxhumana phakathi kohlanga kanye ne-cholesterol. Ngamanye amazwe, amaqembu angamazwe angase abe namandla okuba namazinga aphezulu e-cholesterol.
Kubantu abadala, amazinga e-cholesterol esiphelele kufanele abe ngaphansi noma ngaphansi kwama-milligram angu-200 nge-deciliter (mg / dL). Amazinga e-LDL ama-cholesterol ngaphezu kuka-130 mg / dL abhekwa njengophakeme futhi axhumene nezingozi zempilo ezengeziwe.
Kodwa amazinga e-cholesterol ahlukahluka ngobuhlanga nobuzwe kanye nobulili, ngokwe-CDC.
Amadoda angewona amhlophe aseSpanishi anezibalo ezincane ze-cholestolol e-LDL engama-29.4% kanti amadoda angewona amaSpanishi amnyama angama-30.7% namadoda aseMexico aseMexico anesisindo esiphakeme ku-38.8% Kwabesifazane, amanani alinganisela ukulingana kwamaSpanishi amhlophe Abesifazane baseMexico baseMelika bangama-32% no-31.8%, kuyilapho i-LDL ephezulu iphakeme kwabesifazane abamnyama abangamaSpanishi ku-33.6%
Izingozi Eziphakeme Zezifo Zenhliziyo Phakathi kwabase-Afrika baseMelika
I-cholesterol ephakeme nayo idlala indima enkulu ekuthuthukiseni isifo senhliziyo nokushaya isifo . I-cholesterol ingakha ama-plaque anamathele ngaphakathi kwezindonga ze- artery , okuvimbela ukugeleza kwegazi ne-oksijini emzimbeni. Lezi zinhlayiya ze-cholesterol-laden zingase ziqhekeke, zikhulule izingcezu ze-plaque ezingavimbela amathrifu enhliziyweni noma ebuchosheni, okungabangela ukuhlaselwa yinhliziyo noma isifo sohlangothi.
E-United States, izibalo zokufa ezibangelwa isifo senhliziyo zingama-30% aphakeme kubantu base-Afrika baseMelika uma kuqhathaniswa nabantu abamhlophe.
Ucwaningo oluqhutshwa yiDuke Clinical Research Institute lathola ukuthi iziguli zase-Afrika-America eziye zahlaselwa isifo senhliziyo zaziphindwe izikhathi ezingaphezu kweziphindwe kabili kuneziguli ezimhlophe zingakapheli unyaka wokwelashwa. Ukwengeza, ngokwe-CDC, abesifazane base-Afrika nabamaMelika banengozi enkulu yokufa ngesifo senhliziyo kwanoma yibuphi ubuhlanga, ubuhlanga noma ubulili.
AbaseMelika baseMelika akubona kuphela abantu abasengozini enkulu yokuthuthukisa izinkinga zenhliziyo. Ukusabalala kwezinto ezinobungozi ezifana nomfutho wegazi ophezulu , ukukhuluphala, nesifo sikashukela , kwanda kakhulu phakathi kwabesifazane baseSpanishi. AbaseMelika baseMelika nabo babona ukuphakama kwezinkinga zenhliziyo phakathi kwabantu abadala.
Nakuba abacwaningi bebonile ukungafani phakathi kwezizwe nezinhlanga, abaqiniseki ukuthi bangachaza kanjani imiphumela yabo. "Kumele kube khona okunye okuqhubekayo esingakuqondi ngokugcwele," kusho isazi sezinzwa zezidakamizwa u-Rajendra Mehta, MD, esiteshini seDuke University Medical Center.
Yiziphi Izinto Okungeyona Cholesterol Kungaba Umbangela?
Lokho "okunye" okungase kungabandakanyi i-cholesterol ngqo. Ngaphambi kokuba afinyelele eminyakeni engu-50 ubudala, abadala bazo zonke izinhlanga banamazinga afanayo we-cholesterol esiphelele. Ucwaningo lubonisa ukuthi ezenhlalakahle, ezomnotho, indlela yokuphila noma izici zofuzo zingabamba iqhaza ekuchazeni ukuhlukahluka kokubona kwezempilo enhliziyweni phakathi kwezizwe. Isibonelo, abanye ochwepheshe babhekisela ekufinyeleleni okungalingani kokunakekelwa kwezempilo noma ukwehlukana kwamasiko ekuziphatheni kokwelashwa njengesizathu salokhu okungafani okubikiwe. Abacwaningi bathole ukuthi, uma kuqhathaniswa nabamhlophe, abase-Afrika-baseMelika nabase-Hispanics bancane amathuba okuba amazinga e-blood cholesterol ahlolwe.
I-National Health and Nutrition Examination Survey ithole ukuthi cishe ingxenye yalabo bonke abantu abathintekayo abanegazi eliphezulu le-cholesterol empeleni bathatha imishanguzo yabo enqunyiwe nsuku zonke. Ngo-2004 isethulo se-American Heart Association, uDkt. Mehta waphawula ukuthi ukungabi nokuthobela ukwelashwa kwezidakamizwa isikhathi eside kungachaza ukungafani kohlanga ezinesifo senhliziyo.
Isifo sikashukela nokukhuluphala kuphakamisa amathuba engozi yempilo
Izinkinga ezengeziwe zezempilo, ezifana nesifo sikashukela nokukhuluphala, zithonya amathuba okuba umuntu azokuthuthukisa amazinga aphezulu e-cholesterol.
Isifo sikashukela - isimo esiboniswe amazinga aphezulu aphezulu ushukela egazini - sivame kakhulu phakathi kwama-Afrika aseMelika, esithinta abangaphezu kuka-13% kulabo abangaphezu kweminyaka engama-20.
Isifo sikashukela sinzeka lapho umzimba uyeka ukukhiqiza noma uba umqubuzana ne-insulin, i-hormone ekhishwa ama-pancreas futhi kusiza ukulawula amazinga ashukela. Amazinga ashukela ongajwayelekile angalimaza izitho eziningi, kufaka phakathi nenhliziyo.
Izifo zenhliziyo yimbangela yokufa kwabantu abanesifo sikashukela. Ama-Hispanics, amaMelika aseMelika, ama-Asian-American, kanye namaPacific Islands asengozini enkulu yokuthuthukisa isifo sikashukela sohlobo lwesibili, esivame ukukhula kubantu abadala abaneminyaka engaphezu kwengu-40 (kodwa kuyafana nakakhulu ezinganeni nasebancane).
Abacwaningi bakholelwa nokuthi izici zofuzo zingasiza ekulandiseni ukuhlukahluka kwesifo sikashukela phakathi kwezizwe. Enye inkolelo ithi amanye amaqembu ezinhlanga angase abe nefa okuthiwa "i-grifthty gene", eyasiza okhokho babo ukuba bagcine amandla okudla ngokuphumelelayo. Njengoba iningi lalabo bantu lingasadingeki ukuthi libhekane nezinkathazo zokudla okuncane, igalelo le-thrifty lidlala indima eyingozi ngokubangela isifo sikashukela.
Ukudla okuningi kuye kwaholela kubantu abaningi baseMelika. Ukukhuluphala kubangela ukuba abantu bangene kakhulu ekuthuthukiseni kokubili isifo senhliziyo nesifo sikashukela. Ukukhuluphala kunomthelela omkhulu kubantu abanezinga eliphezulu le-cholesterol elikhona ngaphambili, okwandisa amathuba okuba laba bantu bazokuthuthukisa izinkinga zenhliziyo.
E-United States, abacwaningi bathole ukuthi ukukhuluphala kokukhuluphala kunabantu abaningi kakhulu ngokohlanga nobuhlanga (ngaphandle kwababantu base-Asia baseMelika) uma kuqhathaniswa nabantu abamhlophe.
Ukwengeza, ukukhuluphala kuhlotshaniswa kakhulu ne-cholesterol ephezulu, ukucindezelwa kwegazi, nesifo sikashukela, nakuba amandla alawa maxhumo ahluka ngohlanga, ubuhlanga nobulili.
