1, the first onset of eczema in infants and young children is concentrated in 1-6 months of age (accounting for 73.96%), 0.5 to 3 years of age accounted for 26.63%, which is accompanied by indigestion accounted for 49.11%. This is related to the weak function of the spleen and stomach (incomplete) and incomplete development of the protective barrier of the digestive tract mucosa during infancy. With the growth of age, the spleen and stomach function gradually restored, infant eczema can gradually reduce to heal, but there are some children can be delayed to childhood and adolescence. Therefore, help guide parents to understand the dangers of eczema, especially for those who have a family history of genetic allergies, early detection, early diagnosis, early treatment, and choose the right treatment method, do not have a lucky break and delay the disease. 2, the first onset of most of the causes and the mother pregnancy and lactation diet structure (accounting for 71.10%), the mother before birth to ensure that the child is born smart and healthy, after birth to ensure the adequacy and quality of milk, in the first month after the birth of a large number of fish soup, chicken soup, etc., and it is these “fresh soup” to trigger or aggravate the symptoms of the affected children It is these “fresh and thick soups” that trigger or aggravate the symptoms of the child. It can be seen that although the manifestation of eczema is in the skin, the root of the disease is in the spleen and stomach of the central jiao, and the normal function of the spleen and stomach is directly related to the severity of symptoms. These prove that children’s internal organs are delicate, the shape of Qi is not full, the spleen is often inadequate physiological characteristics, suggesting that we should delay the addition of complementary foods to infants with eczema until 6-7 months, and try to avoid allergenic foods, such as milk, eggs, etc., to reduce or prevent the occurrence of eczema. 3, the survey found that 70.01% of children have a family history of genetic allergies, 53.2% of children have a personal history of allergies (including drugs, food, pollen), indicating that these children have congenital allergic qualities. Clinical reports show that children suffering from eczema are often combined with asthma, because they are both allergic diseases and have a genetic tendency, and the phenomenon of family aggregation is obvious. Clinical data at home and abroad show that 53% to 55% of children with asthma have had infantile eczema, and it is believed that infantile eczema is a precursor symptom of asthma. Therefore, it is necessary to raise awareness of this disease and actively prevent the occurrence of eczema in infants and young children. 4. The following preventive and control measures are proposed: ① Infants and children with family and personal history of allergy are at high risk of developing eczema, so attention should be paid to early detection, early diagnosis and early treatment. (2) Reduce and avoid contact with allergens, delay the addition of complementary foods (egg yolk) until 6-7 months of age, and avoid spicy and fishy foods during breastfeeding. (3) Active prevention, early treatment, reasonable use of drugs, to avoid recurrence. ④Wide health education, popularization of eczema prevention and control knowledge among parents and timely and correct treatment after the onset of eczema is the key to prevention and treatment of eczema in infants and children.
