Allergy is a term that everyone has heard of. In recent years, more and more babies are allergic, but how many people know about allergies? What is allergic? What everyone wants to know most is how to predict whether they will be allergic?
Allergic diseases include allergic rhinitis , asthma, atopic dermatitis, etc. The causes of these diseases are very complex, and they combine genetic and environmental factors. Congenital immune system adjustment problems cause allergic symptoms to occur in these sensitive patients. Genotype changes have also been identified as associated with allergic symptoms. In terms of environmental factors, such as temperature and second-hand smoke, they will also increase the risk of allergies.
Still remember that after a young age, our generation had to face sand holes, parasites, and elixirs, and modern children no longer need to face these hygiene problems of the past, but is it so peaceful? I think the answer is no! What modern children need to face are: allergies, asthma, rhinitis, myopia and mental problems. Why do there be such changes? Everyone wants to know if what kind of changes can be made to avoid this uninvited allergic problem? Is it related to the season of birth?
Past studies have shown that babies born in winter have a higher incidence of atopic dermatitis. Perhaps it is because babies born in winter stay indoors for a long time, are exposed to allergens in the family and increase the risk of respiratory virus infection. Other chemical stimuli in environmental factors (decoration or volatile gases), seasonal climate change, and bacterial cluster distribution are also related to bronchial asthma.
Currently, American research institutions use big data to analyze the association between birth month and allergic diseases (allergic rhinitis, bronchial asthma, atopic dermatitis), and add other allergic data evaluation, such as immunoglobulin E (IgE, allergic immunoglobulin or allergic index) and allergens to explore whether the birth season or month is also related to allergic-related diseases. The following phenomena were found: The relationship between birth month and allergic diseases
The study analyzed the correlation between birth month (January to December) and the incidence of allergic rhinitis, bronchial asthma and atopic dermatitis. It was found from statistical data that bronchial asthma was significantly correlated with birth month. Moreover, the rate of bronchial asthma for school children born in May was the lowest (7.21%), but the highest rate of children born in October was (10.59%). In addition, the incidence of atopic dermatitis and allergic rhinitis was not significantly correlated with the month of birth.
The relationship between birth season and bronchial asthma
Further distinguish the samples according to the birth season, and the correlation between bronchial asthma incidence and birth season was studied. Spring is used as a reference point to analyze the incidence of bronchial asthma in each season. The study results found that the incidence rate of bronchial asthma patients born in autumn is 1.13 times that of patients born in spring.
The relationship between birth season and allergic IgE
In order to confirm the source and association of affecting sex and allergicity in the month of birth, analyzing data from allergic generations also found that children born in autumn have significantly higher immunoglobulin E (IgE) in their bodies than children born in other seasons. The amount of IgE in mothers who give birth in autumn is also relatively higher than that in mothers who give birth in other seasons. This group also proves that children born in autumn are at a higher risk of asthma than children born in spring. Therefore, when babies born in autumn reach 6 months old, the specific allergen index (CAP) has shown obvious allergic data, and the allergic IgE is 1.8 times that of spring.
According to previous Japanese studies, children born in spring and summer, children born in autumn and winter are proven to have a high risk of developing atopic dermatitis. Scholars believe that exposure to dry weather patterns in autumn can lead to dry skin. Dry skin is an important causative factor for atopic dermatitis.
In this study, the main finding was that the incidence of bronchial asthma was higher in children born in autumn (especially for ethnic groups aged 7 to 9 years old). Low temperatures and cold currents also significantly increase the risk of asthma in children with , because cold and low temperatures may lead to excessive growth of bronchial epithelial cells.
Based on this hypothesis, it is speculated that children born in autumn may be exposed to low temperature weather patterns during the first month of their birth. Such a situation may be an important environmental factor that triggers allergic reactions. If you agree with this hypothesis, children born in winter can be exposed to warmer weather patterns in the first month of birth (in spring), so the incidence and allergic signs of asthma are lower.
Children infected with multiple viruses are also related to asthma risk. Such as respiratory tract fusion virus, human interstitial pneumonia virus and rhinovirus. Specific viral infections are also important risk factors for asthma in children. According to a Taiwan study, July to October each year is the peak period for respiratory fusion virus circulating infection. We found that children born in fall were associated with a high risk of asthma, which was consistent with the findings of respiratory fusion virus studies.
In addition, delivery method may also affect the child's risk of asthma, especially caesarean section. However, this study did not collect enough data to analyze the association between delivery mode and allergic diseases, so more research is still needed to understand the possible associations of potential biological mechanisms with environmental risk factors and allergic diseases.
season is just one of the reasons!
The relationship between birth season and asthma may be one of the environmental factors of many complex diseases, and a deeper understanding of the vague sources of allergic diseases can help reduce the risk of early childhood bronchial asthma.
Don’t panic, there is a way to prevent it!
Because the weather in autumn is humid, it is the season for dust mites to reproduce, and dust mites are the main cause of allergies. Therefore, the asthma rate of school children born in autumn will be higher. He also said that if the due date is exactly in autumn, you should try to avoid contact with allergens such as dust mites during pregnancy, and eat less seafood and other foods that may cause allergies, especially after the baby is born, the environment at home should be kept clean.
If pregnant women have a high allergy index, it is easy to make their babies have allergic constitution. It is reminded that pregnant women who are expected to give birth in autumn should stay away from allergens such as dust mites, velvet dolls and other allergens during pregnancy. During pregnancy, allergic foods, such as crabs, shrimps, protein, milk, etc., to reduce the chance of asthma after birth. When starting to feed your baby's side food, you should also be especially careful about the addition of seafood and other aforementioned foods. You can add them "itemally, in small quantities" and carefully observe which foods your baby will have allergic reactions to skin rashes.
. Provide such information is not to cause panic among expectant mothers or concerns of children born in October; the causes of allergic diseases are quite diverse. If you can learn more about information and related causes, parents can pay attention and adjust during the pregnancy process, feeding breast milk, choosing formula milk, adding side foods, and the growth process of children.
