Ochwepheshe bokudla okunomsoco ngokuvamile batusa ukuthi sibe nesidlo sakusihlwa sangaphambi kwesikhathi ukuze siyolala sesiqedile ukugayeka kokudla kwethu. Lokhu kungukuthi sinesidlo sakusihlwa ngaphambi kuka-20-21:00 noma amahora amabili ngaphambi kokulungela ukulala. Iqiniso liwukuthi kufakazelwe ukuthi abantu abalandela lolu hlelo baphathwa umdlavuza webele nowe-prostate ngo-20% uma kuqhathaniswa nalabo abadla ngemva kuka-22:00 ebusuku noma balale ngokushesha ngemva kwesidlo sakusihlwa.
Sizokutshela ukuthi lesi siphetho safinyelelwa kanjani yi-Barcelona Institute for Global Health.
Imikhuba yokudla inganciphisa ingozi yomdlavuza
UDokotela uManolis Kogevinas ungomunye wababhali bocwaningo e-Barcelona Institute for Global Health futhi waphawula ukuthi “zonke izinto eziphilayo ziye zavela ngokuhamba kwesikhathi ukuze zisebenze ngokuhlukile kokubili emini nasebusuku«. Kungakho imikhuba yethu empilweni ingaphawula impilo yethu.
Ucwaningo oluqinisekisayo uthole isidlo sakusihlwa ekuseni ingase inciphise ingozi yomdlavuza, yanyatheliswa kuyi-International Journal of Cancer. Kwabala ku iqhaza de 621 abantu abanomdlavuza wendlala yesinye futhi 1.205 nge umdlavuza webele, ngaphezu kwamadoda angu-872 nabesifazane abangu-1.321 awukho umdlavuza.
Ucwaningo lugxile ku indlela yokuphila kanye ne-chronotype kumuntu ngamunye. Ingabe babekhetha imini noma ubusuku? Ayeyini amahora abo okudla nawokulala? Amavolontiya agcwalise uhlu lwemibuzo kuyo yonke le mibuzo, kanye nokukhuluma ngezinga lawo lokuzivivinya nokuphuzwa kotshwala.
U-27% weziguli ezinomdlavuza webele zilandele izincomo zokuvinjelwa komdlavuza, uma kuqhathaniswa no-31% walezo ezingazange ziwulandele. Ngokuqondene namadoda anomdlavuza wendlala yesinye, imiphumela yayifana.
Ngaphezu kwalokho, kwabuye kwacatshangelwa imikhuba ababenayo unyaka owodwa ngaphambi kokuxilongwa noma ngaphambi kokuxoxwa nabo okocwaningo. U-7% wamavolontiya athi abe nokudla okulula ngemva kwesidlo sakusihlwa, kodwa ucwaningo lwalugxile ekudleni okuyinhloko kuphela.
Ukuphazamisa isigqi se-circadian kunomthelela omubi
UManolis Kogevinas uchaza ukuthi ingozi ye-prostate kanye nomdlavuza webele kuboniswe ukuthi ihlobene nayo sebenza amashifu ebusuku futhi ushintshe isigqi se-circadian. Eqinisweni, ucwaningo lwe-Dana-Farber Cancer Institute lweluleka ukuthi udle ngokuhambisana newashi lemvelo lomzimba wakho ukuze unciphise amathuba okuthola umdlavuza webele ophindelelayo.
UMarinac, umcwaningi waseDana-Farber, waphawula ukuthi «Ucwaningo luthole ukuthi abantu abadla ebusuku kakhulu banamazinga aphezulu okukhuluphala kanye namaphrofayili amabi kakhulu we-metabolic. Futhi ikakhulukazi, sithole ukuthi abantu abane- isikhathi eside sokuzila ukudla ebusuku, okungase kusho ukudla okuncane ebusuku, ube nokulawula kangcono ushukela egazini kanye a ingozi ephansi yokubuya komdlavuza".
Kodwa emuva esifundweni esiyinhloko kulesi sihloko, amaqembu womabili amavolontiya abekwe ekudleni okufanayo, futhi ososayensi benza ukuhlaziya okubanzi ukuze baqinisekise ukuthi babangelwa isikhathi sokudla kunezinye izici.
