Uyazi ukuthi ukubhema kuyinto embi kakhulu ongayenza emzimbeni wakho-kusuka ngaphakathi nangaphandle, ugwayi uyingozi empilweni yakho. Kodwa lapho othile eyeka umkhuba ngokuhle, kungakanani nje “angakuhlehlisa” uma kuziwa kuleyo miphumela engemihle ebulalayo? Yebo, ucwaningo olusha olushicilelwe kumagazini we-American Heart Association, Ukusakazwa: I-Cardiovascular Genetics, kukhanyisa ukukhanyiswa kwesikhathi eside sokubhema ... ne-tbh, akukuhle.

Abacwaningi bahlaziya amasampula egazi acishe abe ngu-16 000 kubantu ababhemayo, ababekade bebhema, nababengabhemi. Bathole ukuthi intuthu kagwayi ixhumene nomonakalo ebusweni be-DNA-ngisho nakubantu abayeke emashumini eminyaka ngaphambili.

“Ucwaningo lwethu luthole ubufakazi obuqand’ ikhanda bokuthi ukubhema kunomthelela ohlala isikhathi eside emishinini yethu yamangqamuzana, okuwumthelela ongathatha iminyaka engaphezu kwengu-30,” kusho umlobi wocwaningo oluphambili uRoby Joehanes, Ph.D. Ucwaningo lubheke ngqo i-DNA methylation, inqubo amaseli alawula ngayo umsebenzi wezakhi zofuzo, bese kuthinta ukuthi izakhi zakho zofuzo zisebenza kanjani. Le nqubo ingenye yezindlela lapho ukuvezwa kukagwayi kungenza ababhemayo babe nomdlavuza, i-osteoporosis, nezifo zamaphaphu nezenhliziyo.

Nakuba imiphumela idumaza, umbhali wocwaningo uthe babona okuphambene nalokho abakutholile: Lokhu kuqonda okusha kungasiza abacwaningi ukuba bakhe izindlela zokwelapha eziqondiswe kulezi zakhi zofuzo ezithintekile futhi mhlawumbe zivikele nezifo ezithile ezihlobene nokubhema.

E-US kuphela, abantu abadala abalinganiselwa ezigidini ezingama-40 njengamanje babhema osikilidi, ngokusho kwedatha ye-CDC kusuka ngonyaka ka-2014. (Singathemba nje ukuthi lelo nani liye laqhubeka ukwehla kusukela lapho.) Ukubhema ugwayi nakho kuyimbangela ehamba phambili yezifo ezingavikeleka nokufa ngaphezu kuka Abantu baseMelika abayizigidi ezingu-16 baphila nesifo esihlobene nokubhema. (Ababhemayo bezenhlalo balalela: Ukuthi Ugwayi Wentombazane Ebusuku Akuwona Umkhuba Ongenabungozi.)

"Yize lokhu kugcizelela imiphumela esasele yesikhathi eside yokubhema, izindaba ezimnandi ukuthi uzosheshe uyeke ukubhema, uzobe usungcono," kusho umlobi ocwaningayo uStephanie London, M.D., iphini lenhloko yeNational Institute of Environmental Health Sciences. UJoehanes ukuthethelela lokhu, echaza ukuthi uma abantu sebeshiyile, iningi lamasayithi e-DNA okukhulunywa ngawo abuyele emazingeni "'angabhemi' ngemuva kweminyaka emihlanu, okusho ukuthi umzimba wakho uzama ukuziphilisa ngemiphumela eyingozi yokubhema ugwayi."
