Sihlala siphinda-phinda ukuba kulungile ukutshintshela kwi-e-cigarettes kodwa kubalulekile ukumisa konke ukusetyenziswa kwecuba. Kwakhona, oku kucaciswa ngophononongo lwaseMelika olubonisa ukuba ukuba ukuyeka ukutshaya kuyiphucula impilo yemiphunga nakubantu ababetshaya kakhulu, ukunciphisa ukutshaya kuhlala kungonelanga ukuyigcina.
ABATSHYAYO, ABATSHYAYO...
Uphando olwenziwe liqela elivela kwiiyunivesithi ezininzi zaseMelika lusekwe kwidatha enxulumene nabathathi-nxaxheba abayi-3.140 kuphononongo olukhulu " Uphuhliso lweMngcipheko we-Coronary Artery kubantu abadala abancinci » (CarDIA).
Ngomndilili weminyaka engama-25 ekuqaleni kophononongo, bathathe inxaxheba iminyaka engama-30 ngokujongwa ngokwezonyango kwaye baphumelele iimvavanyo ze-spirometry, kunye nesifuba se-15, i-20 kunye ne-25 iminyaka emva kokubhaliswa kwabo.
Umbhali oyintloko wesifundo Amanda Mathew, kwiNorthwestern University School of Medicine, ithi: “ Abathathi-nxaxheba babuzwa imibuzo malunga nokusela kwabo icuba minyaka le, nto leyo enciphisa ukukhetha. Oku kusivumele ukuba sibonise utshintsho kwimikhwa yabo ekuhambeni kwexesha".
Abaphandi baqaphela ukuba, xa kuthelekiswa nalabo abangazange batshaye, abona bantu batshaya kakhulu bafumana ukuhla okukhulu ekusebenzeni kwemiphunga. Eli qela lalinamathuba angama-26 okuphinda aphuhlise i-pulmonary emphysema kunye namaxesha asi-8 amathuba okuba aphuhlise isifo semiphunga esithintelayo.
Abaphandi baphinde bajonge abantu abatshayayo ngamaxesha athile, iqela elingazange lifunde kwiimvavanyo zeklinikhi. Abo banembali 
ishwankathelwe ukuya kutsho ngaphantsi kwe-10 PA (i-PA okanye ipakethe yonyaka yinxalenye ebalwa ngokuphinda-phinda inani leepakethi zecuba atshaywayo ngosuku ngenani leminyaka apho umntu ebetshaya).
Abaphandi bathelekisa iqela labo batshaya ngokukhawuleza (6,4 BP) kwabo bayekayo (kwaye i-BP yabo yayiyi-9,8 ngaphambili).
Bafumanisa ukuba phezu kwayo nje imbali yabo njengabatshaya kakhulu, abo baye bayeka ukutshaya babeyilondoloze kakuhle imiphunga yabo. Umngcipheko wabo wokuba neemphysema wancitshiswa xa uthelekisa nabo batshaya kancinci.
« Samangaliswa kukufumanisa ukuba umngcipheko wesifo wawungaphantsi kwabo baye bayeka ukutshaya kunaphakathi kweqela elachazwa njengeentshayi zamanqaphanqapha nezizinzileyo. Yaye oku kwanaphakathi kwabo babechanabeke ecubeni ixesha elide“, uqukumbela ngelithi uGqirha Mathew. Wongeza: " Akukho mda wokhuseleko xa kufikwa kwicuba. Ukuyeka ukutshaya linyathelo lokuqala elilungileyo, kodwa ukuyeka umphelo kuseyeyona ndlela isebenzayo yokunciphisa umngcipheko wesifo semiphunga.".
Iziphumo zapapashwa kwijenali I-American Journal ye-Respiratory and Critical Care Medicine.
