Melbourne becomes the allergy capital? East Asia is more likely to "migrate to the second generation"

Melbourne is recognized as the capital of sports events in Australia, but recently medical researchers want to put another title on Melbourne's head-the allergy capital. In the past 20 years, food allergies have become more common, and no one seems to know what the reasons are.
It is understood that the number of people with food allergies in Australia is on the rise. Peanuts, nuts, milk, eggs and sesame are all common allergens. In 2010, 10% of newborns in Melbourne were found to have food allergies. Recently, another medical team conducted an investigation on Melbourne’s allergies, describing Melbourne as “the place with the highest allergy rate in the world”.
However, the team also found that the number of infants and young children with allergies in the Geelong area was significantly lower than the Melbourne average. This data seems to give scientists a hint that they have found a direction to explore the causes of allergies.
Dr. Raymond Mullins of the University of Canberra said that the past data are all correct, but the sample size is too small, and the larger the sample size, the more accurate the conclusions drawn. He and his colleagues conducted research on the adolescents' immediate allergies and found that although the number of allergies is not as alarming as that of newborns, it is still distressing.
The HealthNuts survey conducted 5 years ago studied 5276 infants under one year old in Melbourne and surrounding areas. Now the children are over 6 years old and have undergone multiple allergy tests. The latest results are published recently "Epidemiology (Epidemiology)" magazine, the results are unexpected. 12% of 3-month-old children are allergic to peanuts, 9% are allergic to eggs, and less than 1% are allergic to sesame. After one year, half of the children who are allergic to eggs are no longer allergic, but when the children grow up At the age of 1, only 4% of peanut allergies are no longer allergic.
In addition, the study has drawn some interesting conclusions. If the child’s parents were born in East Asia but the child was born in Australia, then the child’s risk of food allergy is much higher than other children; and if the child was born in East Asia and then immigrated to Australia, the chance of allergies is much smaller. In addition, the allergy rate among Chinese people is also increasing, so the researchers guessed that there is a big difference between urban and rural areas. In addition, various factors such as the child's birth season and the mother's vitamin level may affect the allergy rate.
