Focus 1: Lead content
Lead is the only trace element that the human body does not need, which affects intelligence and bone development, causes indigestion and anemia, and destroys renal function and immune function. Even if there is 0.0 1 microgram of lead in human body, it will do harm to health. Therefore, the most important thing for children's physical examination is to measure lead.
Focus 2: Hemoglobin
Anemic children are often 2 ~ 10 cm shorter than normal children of the same age, mostly because of iron deficiency. Iron deficiency will reduce children's immunity, affect cognitive ability, and lead children to behave strangely and hyperactively.
Focus 3: Zinc, Calcium and Magnesium
80% of children with zinc below the normal level 1/2 have severe developmental retardation. Therefore, zinc intake is very important for children to grow taller. Calcium and magnesium are also essential trace elements, which complement each other and promote development. Calcium deficiency and hypercalcemia will affect growth and development, and even cause diseases. Therefore, calcium can't be supplemented casually, and it must be supplemented according to the doctor's advice after testing.
Focus 4: Bone age determination
It mainly analyzes the height potential and development of children according to X-rays. According to scientific research, the development of children's bone age tends to advance, which will seriously affect his height and figure, causing him to stop growing when he is 16 years old. Therefore, the determination of bone age during physical examination is also essential.
In addition to the above key examination items, children's physical examination has another advantage, which is that it can detect some diseases and play a very effective role in prevention and treatment. Next, let's take a look at what diseases can be detected by children's physical examination.
What diseases can children's physical examination find out?
1, cardiovascular diseases
Most of these diseases are also caused by obesity. Most parents think that suffering from this disease is the patent of middle-aged and elderly people, but it is not. According to the data, about 20% of obese children suffer from this adult disease. Therefore, limiting diet and exercising more are the keys to prevent cardiovascular diseases.
2. Dental caries
In China, about 77% of 5-year-old children have dental caries, while 70% of 5-year-old children in developed countries (especially Nordic countries) have no dental caries. Therefore, oral examination is essential in children's physical examination at least twice a year.
3. Anemia
At present, about 2 billion people in the world suffer from anemia, of which more than 70% are children. In China, the incidence of anemia in 7-year-old children is 42. 1% for boys and 44.8% for girls. Despite the continuous improvement of living standards and the increase of "little fat people", their diet structure is mostly unqualified, they prefer high-fat and high-sugar, and their intake of iron-containing food is insufficient. If your child has symptoms such as loss of appetite, irritability, crying, weight loss, stunting, decreased IQ, memory and learning ability, it is necessary for you to take him for a physical examination to see if he is anemic.
