The bacterium living on urban children is different from that of rural children. The differences are most in toddler.
The University of Helsinki is investigating how the habitat affects inflammation-related illnesses. The purpose is to find out why there are more allergies in cities than in the country. The study compares the living bacteria of the skin of North Karelian and Helsinki children.
-We are working in the Helsinki City and in the small municipalities of North Karelia and in children living in sparsely populated areas. The aim was to find out about the children’s extremes in the residential area, says researcher and doctoral student Jenni Lehtimäki .
According to the latest results, bacterial bacteria living on the skin of living children in the city are different from those living on the ground.
“There is strong evidence that allergic diseases are more common in cities than in rural areas across Europe,” says Lehtimäki.
The study was carried out in co-operation with the Health and Welfare Institute.
-With a baby the difference is visible somewhat, but the toddler difference is at its highest, says Lehtimäki.
Lehtimäki believes that babies will get their parents from either a rural or urban type of bacteria on their skin. Differences between toddlers may be due to the environment.
-They are studying the environment and are outdoors.
There is no difference between the teens.
There may be two reasons for this. Skin characteristics can change with puberty. Another option is that teenagers live a very similar life in spite of the environment. For example, they do not go to school as much as younger children.
“I do not believe in massive ridicule”
Sonja Hietaranta , who came out of the park in Tampere’s Little Kakkonen park with her children, believes that children’s allergies are affected by environmental sterility.
-If the child lives in a really sterile environment, I think he has more allergies.
The Hietaranta family has three children. The family lives in Tampere, but has lived in Helsinki previously. None of the children have had allergies.
– Our children have spent a lot in the yard and have been in contact with dogs and horses.
-On the outside, the kids are dealing with poppies.
Also, family member Jouni Vähäkyy does not believe that there is a big difference between the rural and urban children .
. -The results may be visible in a bigger picture, but I do not believe in a massive break.
There is 2 children in the town. Another child has had allergic tests due to dyspnea. However, he did not diagnose allergy.
“The impact of rural areas on health”
The country Sarkola living in Sofia Lahtisen j a Juho Lahti concluded that the findings sound more interesting. The family has three children, none of whom have any allergies.
-These studies show how important the rural impact on health is, Lahtinen says.
The family has an organic sheepskin. In addition, they have dogs, goats and chickens, for example.
-When children live on land with a variety of domestic animals and are at work, they can not always be avoided. It is good for their resistance, Lahti says.
More research is needed
According to Lehtimäki, the interest of researchers in the skin has increased recently. Skin may have a greater significance for the human immune system.
– There are many different layers with immune system cells. The cells transmit information from outside to the body. They are like dialogue.
-Excellent changes may be a gateway to the development of allergies. However, more research is needed before certain information is available.
