Futhi bathi kwakungafanele ukuhlanganyela ekuzaleni ebusika.
Onke amantombazane azi ukuthi zingabalwa kanjani kahle izinsuku lapho amathuba okukhulelwa azobe ephakeme kakhulu. Wake wazibuza ukuthi kunezikhathi lapho kunganconywa ukukhulelwa izingane? Kuvela ukuthi zikhona.
Ososayensi bathi izingane ezikhulelwe phakathi kukaJanuwari noMashi zinamathuba amaningi okuba nobunzima bokufunda njenge-dyslexia noma ukunakekelwa kokushoda kokungasebenzi kahle. Okungenani, odokotela abavela emanyuvesi aseGlasgow naseCambridge, insizakalo yezempilo yase-UK kanye nohulumeni waseScotland banesiqiniseko salokhu.
Ochwepheshe bafunde izibalo zokusebenza kwezemfundo phakathi kwezinkulungwane ezingama-800 zezingane zaseScotland ngo-2006-2011 futhi bathola ukuthi izingane ezizalwe ekwindla, okungukuthi, ezikhulelwe engxenyeni yokuqala yonyaka, ikakhulukazi ngemuva kontanga bazo. Ikakhulu, izinkinga ngokusebenza kahle ezifundweni ziyabonwa ku-8,9%, ngenkathi phakathi kwezingane ezikhulelwe kusuka ngoJuni kuya kuSepthemba, leli nani liyi-7,6% kuphela.
Ososayensi babona isizathu sokuntuleka kwe-vitamin D. Le nkinga yaqala ukuzwakala ngo-2012, lapho odokotela bencoma ngokuqinile ukuthi bonke abesifazane bathathe i-vitamin D ekwindla nasebusika, ama-microgram angu-10 ngosuku. Kodwa, cishe, odokotela bathi, abaningi babo namanje abasilandeli lesi seluleko.
“Uma amazinga kavithamini D engesikhathi esithile sonyaka, sinethemba lokuthi ukulandela kabanzi izincomo zodokotela kuzolungisa izinto,” kusho uprofesa waseCambridge uGordon Smith, kubhala iThe Telegraph. "Yize lolu cwaningo lungalinganisanga amazinga kavithamini D kwabesifazane, luhlala luyincazelo engenzeka kakhulu yenkambiso yezinkinga zokufunda."
Phambilini ososayensi baseSweden nabo besaba ukuxilongwa okubi okuvela ezinganeni ngenxa yokushoda kukavithamini D emzimbeni kamama phakathi ne-trimester yesithathu. Lezi zingane, ngokusho kwedatha yazo, kungenzeka zibe nesifo se-celiac - isifo se-celiac.
