Koj paub tias kev haus luam yeeb yog qhov phem tshaj plaws uas koj tuaj yeem ua rau koj lub cev-los ntawm sab hauv tawm, luam yeeb tsuas yog txaus ntshai rau koj kev noj qab haus huv. Tab sis thaum ib tus neeg tawm ntawm tus cwj pwm kom zoo, tsuas yog ntau npaum li cas lawv tuaj yeem "rov ua dua" thaum nws los txog rau cov kev phom sij txaus ntshai? Zoo, ib txoj kev tshawb fawb tshiab luam tawm nyob rau hauv American Heart Association phau ntawv journal, Circulation: Cardiovascular Genetics, tab tom teeb pom kev haus luam yeeb ntev hneev taw ... thiab tbh, nws tsis zoo.

Cov kws tshawb fawb tau tshuaj xyuas yuav luag 16,000 cov ntshav los ntawm cov neeg haus luam yeeb, cov neeg haus luam yeeb yav dhau los, thiab cov tsis haus luam yeeb. Lawv pom tias cov pa luam yeeb tau txuas rau kev puas tsuaj rau saum npoo ntawm DNA-txawm rau cov neeg uas txiav luam yeeb ntau xyoo dhau los.

"Peb txoj kev tshawb fawb tau pom cov pov thawj txaus ntseeg tias kev haus luam yeeb muaj kev cuam tshuam ntev rau peb cov tshuab molecular, ib qho kev cuam tshuam uas tuaj yeem kav ntev dua 30 xyoo," tus kws tshawb fawb thawj coj Roby Joehanes, Ph.D. Txoj kev tshawb fawb tshwj xeeb saib DNA methylation, txheej txheem uas cov cell muaj qee qhov kev tswj hwm cov haujlwm hauv noob, ua rau cuam tshuam li cas koj cov noob ua haujlwm. Cov txheej txheem no yog ib txoj hauv kev uas kev haus luam yeeb tuaj yeem ua rau cov neeg haus luam yeeb ua rau mob qog noj ntshav, osteoporosis, thiab mob ntsws thiab kab mob plawv.

Txawm hais tias cov txiaj ntsig tsis txaus siab, tus kws tshawb fawb tau hais tias lawv pom muaj qhov cuam tshuam rau lawv qhov kev tshawb pom: Qhov kev pom tshiab no tuaj yeem pab cov kws tshawb fawb tsim kho cov hom phiaj cuam tshuam rau cov noob no thiab tej zaum kuj tiv thaiv qee yam kab mob ntsig txog kev haus luam yeeb.

Hauv Asmeskas ib leeg, kwv yees 40 lab tus neeg laus tam sim no haus luam yeeb, raws li CDC cov ntaub ntawv los ntawm 2014. (Peb tsuas tuaj yeem cia siab tias tus lej tau txuas ntxiv txo txij li.) Kev haus luam yeeb tseem yog qhov ua rau muaj kev tiv thaiv kab mob thiab tuag-ntau dua 16 lab tus neeg Asmeskas nyob nrog tus mob ntsig txog kev haus luam yeeb. (Cov neeg haus luam yeeb hauv zej zog mloog: Cov Hluas Nkauj Hmo Ntuj Tawm Cigarette tsis yog ib qho kev phom sij.)

"Txawm hais tias qhov no qhia txog qhov cuam tshuam ntev ntev ntawm kev haus luam yeeb, xov xwm zoo yog qhov sai dua koj tuaj yeem txiav luam yeeb, qhov zoo dua rau koj," said Stephanie London, MD, tus thawj coj ntawm National Institute of Environmental Health Sciences. Joehanes vib nas this, piav qhia tias ib zaug tib neeg txiav tawm, feem ntau ntawm cov chaw DNA hauv nqe lus nug rov qab mus rau "'tsis haus luam yeeb' qib tom qab tsib xyoos, uas txhais tau hais tias koj lub cev tab tom sim kho nws tus kheej ntawm qhov teeb meem ntawm kev haus luam yeeb."

Nyeem: Nws yeej tsis lig dhau lawm.
