Esi sizathu sokuba abantwana babe zizidenge

Umgangatho ophezulu wobudenge kubantwana unesizathu esihle, ngaphandle koko ukungabikho komsebenzi weemoto Kwisizukulwana esitsha, kukho iintsingiselo ezininzi eziye zangena ekutyeni kwethu kwaye zahlala ezingqondweni zabantwana bethu ukuphakamisa izinga lobudenge babantwana kabini okanye ngaphezulu.

Ukusukela ngeminyaka yee-XNUMX, iye yongezwa i-fluoride kumanzi etephu kumazwe athile ahambele phambili kwezoshishino ukukhusela ekuboleni kwamazinyo.

Kwafunyaniswa ukuba amanqanaba aphezulu kakhulu oxinaniso lwale nto abangela umonakalo omkhulu engqondweni, ngelixa amanqanaba oxinaniso afunyanwa kumanzi etephu akabinabungozi ngokubanzi.

"Siye saqaphela ukuba kukho ukuthandabuza okukhulu malunga neengozi ze-fluoride, ngakumbi kubasetyhini abakhulelweyo kunye nabantwana abancinci," uKristen Till waseYunivesithi yaseYork eCanada, umbhali okhokelayo wophando olupapashwe kwiphephancwadi i-JAMA Pediatrics, utshele i-AFP.

Iindlela zokwandisa ubukrelekrele

Ngokutsho kwabaphandi, amanzi ane-fluoridated asasazwa malunga ne-66% yabemi base-United States, i-38% yabemi baseCanada, kunye ne-3% yabemi baseYurophu.

Uphononongo luphonononge malunga nama-601 oomama nomntwana ngababini kwizixeko ezithandathu zaseKhanada, i-41% yabo bahlala kwiindawo ezibonelelwa ngamanzi ane-fluoridated evela kwabasemagunyeni bakamasipala.

Abaphandi baqaphele ukuba ukunyuka ngalunye kwi-concentration ye-fluorine kumchamo wabasetyhini abakhulelweyo nge-milligram enye ilitha yayinxulumene nokuncipha kwe-IQ ye-4,5 kumakhwenkwe phakathi kweminyaka emithathu kunye nemine ubudala, kodwa kungekhona kumantombazana.

Ukuthathela ingqalelo isixa se-fluorine umama asidla imihla ngemihla kunokuba isixa kumchamo, abaphandi baqaphela ukuba ukunyuka kwemiligram nganye kuhambelana nokuncipha kwamanqaku e-3,7 kwi-IQ yamakhwenkwe kunye namantombazana.

Nangona kunjalo, iingcali ezininzi kwiinkalo ezahlukeneyo ukusuka kumanani kunye ne-toxicology ukuya kwi-neuroscience, ziye zalugxeka uphononongo.

"Ndicinga ukuba izigqibo zincinci kwaye zilinganiselwe," utshilo uStuart Ritchie, ugqirha wengqondo kwiKholeji yaseKing eLondon. Zinokubaluleka kwiseti ebanzi yezifundo ngalo mba, kodwa zizodwa azinakuqhubela phambili ingxoxo malunga nobungozi befluorine. ”

Ngokulindela ingxabano, i-Gamma Pediatrics ikhutshwe, kwisinyathelo esingaqhelekanga, inkcazo yokucacisa, ithi ukupapasha isifundo kwakungeyona "isigqibo esilula".

Ukufaka isandla ekunciphiseni izinga lokubola kwamazinyo e-United States, ukongeza i-fluorine emanzini yenye ye-XNUMX enkulu yempumelelo yezempilo yoluntu kwi-XNUMXth inkulungwane, ngokutsho kwamaZiko oLawulo lweSifo kunye noThintelo (CDC).
