Rezultati istraživanja veterinarskih antibiotika
Dec 21, 2021
Kako bi pronašao izravne dokaze, istraživački je tim počeo osmišljavati relevantne metode istraživanja od 2010. godine; od 2012. svake se godine prikupi oko 1500 uzoraka urina školske-djece u Jiangsu, Zhejiangu i Šangaju, a prikupljanje će se nastaviti do 2014. U međuvremenu su istraživači istraživačke grupe istražili i ustanovili visoko{6}}metoda detekcije za razne antibiotike u uzorcima urina nakon dugotrajnog-laboratorijskog rada.
In order to study the impact of childhood antibiotic use or exposure to food antibiotics on children's fat production, the research team used antibiotic biomonitoring methods for the first time in the world, and conducted urine samples of 586 school-age children aged 8 to 11 collected in Shanghai in 2013. The results of the study determined that there were 21 antibiotics in urine, including 5 macrolide antibiotics, 2 -lactam antibiotics, 3 tetracycline antibiotics, 4 quinolone antibiotics, 4 sulfonamide antibiotics and 3 One or more of the 21 antibiotics were detected in the urine of 79.6 percent of school-age children.
Kako bi razjasnili odnos između antibiotika i pretilosti, znanstvenici su djecu podijelili u tri skupine od niske do visoke prema koncentraciji veterinarskih antibiotika u mokraći.
After adjusting for factors such as gender, age, parent's education level, income level, puffed food intake, smoking status of relatives and friends, the study found that compared with children in the low concentration group, the risk of obesity for children in the medium and high concentration groups is 1.99 times to 3 times of the low concentration group.
At the same time, the research team used the body mass index and waist circumference to determine whether children were overweight or obese. After further analysis of urine, it was found that exposure to veterinary antibiotics or antibiotics mainly used in animals is significantly related to children's overweight or obesity.
To također pokazuje da postoji pozitivna povezanost između izloženosti antibioticima uglavnom iz hrane i rizika od pretilosti u djetinjstvu. Istraživači vjeruju da ekološki izvori veterinarskih antibiotika ulaze u ljudsko tijelo uglavnom kroz kontaminiranu vodu i hranu.
U ovoj studiji nije uočena pretilost ili prekomjerna tjelesna težina, što je značajno povezano s medicinskim antibioticima koji se uglavnom koriste u populaciji. Istraživački tim vjeruje da je upotreba medicinskih antibiotika u biti kratkoročna-izloženost visokim-dozama, dok je izloženost antibioticima iz hrane ili okoliša dugoročno-niska{{ 3}}izloženost dozi. Ovaj rezultat sugerira da uzorak izloženosti antibioticima može biti jedan od važnih čimbenika koji utječu na promicanje proizvodnje masti.
The research team stated that in 2013, the use of antibiotics in China reached 162,000 tons a year, accounting for about half of the world's consumption, 52 percent of which were for veterinary use, 48 percent for human use, and more than 50,000 tons of antibiotics were discharged into the water and soil environment.
In view of the universality of population antibiotic exposure and the huge pressure on personal health and social development caused by current obesity, they will expand the test sample size, and use longitudinal research combined with animal model research to further explore the effects of children's exposure to low-dose antibiotics on children's growth and development. Health effects.
Istraživački tim testira i analizira prikupljene uzorke pitke vode i hrane kako bi dodatno razjasnio glavne izvore spomenutih antibiotika
