Ucwaningo olusha lusikisela ukuthi kwabesifazane abaneminyaka engu-40 kuya phezulu, impendulo ibonakala inguyebo.
"Okokuqala, ngithanda ukugcizelela ukuthi ukuvivinya umzimba noma ukwenza uhlobo oluthile lokuzivocavoca kunenzuzo nganoma yisiphi isikhathi sosuku," kuphawula umbhali wocwaningo uGali Albalak, ikhandidethi yobudokotela emnyangweni wezokwelapha zangaphakathi eLeiden University Medical Center abase Netherlands.
Impela, imihlahlandlela eminingi yezempilo yomphakathi iyiziba indima yokubeka isikhathi ngokuphelele, u-Albalak uthe, ekhetha ukugxila kakhulu “ekubeni kangaki, isikhathi esingakanani futhi kufanele sisebenze kangakanani” ukuze sithole izinzuzo eziningi zezempilo yenhliziyo.
Kodwa ucwaningo luka-Albalak lugxile ekungeneni nasekuphumeni komjikelezo wamahora angama-24 wokuvuka - lokho ososayensi abakubiza ngokuthi isigqi sokujikeleza. Ubefuna ukwazi ukuthi kungenzeka yini kube “nenzuzo eyengeziwe yezempilo ekusebenzeni komzimba” okusekelwe ekutheni abantu bakhetha nini ukuzivocavoca.
Ukuze bathole lokhu, yena nozakwabo baphendukela kudatha eyayiqoqwe ngaphambilini yi-UK Biobank eyayilandelela amaphethini okusebenza komzimba nesimo senhliziyo yenhliziyo phakathi kwabesilisa nabesifazane abacishe babe ngu-87,000.
Abahlanganyeli babeneminyaka esukela kwengama-42 kuye kwengama-78, futhi cishe u-60% kwakungabesifazane.
Bonke babenempilo lapho befakwe i-tracker yomsebenzi egade amaphethini okuzivocavoca phakathi nesifundo iviki.
Ngokulandelayo, isimo senhliziyo sagadwa ngokwesilinganiso seminyaka eyisithupha. Ngaleso sikhathi, ababambiqhaza abangaba ngu-2,900 baba nesifo senhliziyo, kuyilapho abangaba ngu-800 benesifo sohlangothi.
Ngokuhlanganisa "izigameko" zenhliziyo ngokumelene nesikhathi sokuzivocavoca, abaphenyi banqume ukuthi abesifazane abavocavoca "ekuseni kakhulu" - okusho ukuthi phakathi kuka-8 ekuseni no-11 am - babonakala bebhekene nengozi ephansi kakhulu yokuhlaselwa yinhliziyo noma unhlangothi.
Uma kuqhathaniswa nabesifazane ababesebenza kakhulu kamuva emini, labo ababesebenza kakhulu ekuseni noma ekuseni batholakala benengozi ephansi yama-22% kuya ku-24% yesifo senhliziyo. Futhi labo ababezivocavoca ngezikhathi zasekuseni kakhulu babona ingozi yabo yokushaywa unhlangothi yehla ngo-35%.
Nokho, inzuzo eyengeziwe yokuzivocavoca ekuseni ayizange ibonakale phakathi kwamadoda.
Kungani? "Asizange sithole noma iyiphi ithiyori ecacile engachaza lokhu okutholakele," kuphawula u-Albalak, wengeza ngokuthi kuzodingeka ucwaningo olwengeziwe.
Uphinde wagcizelela ukuthi iziphetho zethimba lakhe zisekelwe ekuhlaziyeni okuqaphile kwezinqubo zokuzivocavoca, esikhundleni sokuhlola okulawulwayo kwesikhathi sokuzivivinya. Lokho kusho ukuthi nakuba izinqumo zesikhathi sokuzivocavoca zibonakala zithinta impilo yenhliziyo, kusengaphambi kwesikhathi ukuphetha ngokuthi kubangela ingozi yenhliziyo ukuthi ikhuphuke noma yehle.
U-Albalak uphinde wagcizelela ukuthi yena nethimba lakhe “bazi kahle ukuthi kunezinkinga zomphakathi ezivimbela iqembu elikhulu labantu ukuthi lizivocavoce ekuseni.”
Noma kunjalo, okutholakele kusikisela ukuthi “uma unethuba lokusebenza ekuseni - ngokwesibonelo ngosuku lwakho lokuphumula, noma ngokushintsha uhambo lwakho lokuya emsebenzini nsuku zonke - ngeke kube buhlungu ukuzama ukuqala usuku lwakho ngomsebenzi othile."
Okutholiwe kushaye uchwepheshe oyedwa njengokuthakaselayo, okumangazayo futhi okungaqondakali ngandlela thize.
“Incazelo elula ayifiki engqondweni,” kuvuma uLona Sandon, umqondisi wohlelo womnyango wezokudla okunempilo emtholampilo we-UT Southwestern Medical Center's School of Health Professions, eDallas.
Kodwa ukuze uthole ukuqonda okungcono ngalokho okwenzekayo, uSandon uphakamise ukuthi ukuya phambili kungaba usizo ukuqoqa ulwazi mayelana namaphethini abahlanganyeli abadlayo.
"Kusukela ocwaningweni lokudla okunempilo, siyazi ukuthi ukusutha kukhulu ngokudla kwasekuseni kunokudla kwakusihlwa," kusho yena. Lokho kungakhomba umehluko endleleni i-metabolism esebenza ngayo ekuseni uma iqhathaniswa nakusihlwa.
Lokho kungasho ukuthi "isikhathi sokudla ngaphambi kokuzivivinya singaba nomthelela kumetabolism yezakhi kanye nokugcinwa okungase kube nomthelela engozini yenhliziyo nemithambo yegazi," kwengeza uSandon.
Kungenzeka futhi ukuthi ukuzivocavoca kwasekuseni kuvame ukwehlisa amahomoni okucindezeleka kunokuzivocavoca kwasebusuku. Uma kunjalo, ngokuhamba kwesikhathi lokho kungase kube nomthelela empilweni yenhliziyo.
Kunoma ikuphi, uSandon wahambisana nokuvuma kuka-Albalak ukuthi “noma ikuphi ukuvivinya umzimba kungcono kunokungavivinyi umzimba.”
Ngakho “ukuzivocavoca ngesikhathi sosuku uyazi ukuthi uzokwazi ukunamathela esimisweni esijwayelekile,” kusho yena. Futhi uma ukwazi, thatha ikhefu lokuzivivinya ekuseni esikhundleni sekhefu lekhofi.”
Umbiko ushicilelwe Nov. 14 ku-European Journal of Preventive Cardiology.
Ulwazi olwengeziwe
Kuningi ngokuzivocavoca nempilo yenhliziyo e-Johns Hopkins Medicine.
