What are the physical and mental health problems of children?

1, malnutrition and obesity coexist among primary and secondary school students. Because of the large number of these two groups, this situation is called "bimodal phenomenon" by experts. Malnutrition of children in remote areas is caused by insufficient intake of calories and protein. Urban children, on the other hand, are partial to food, picky eaters and eat too many snacks. Compared with malnutrition, the more serious problem is obesity. In the past two years, the growth rate of obese children is amazing. Obesity has an impact on children's physical and mental development. Obesity in children will lead to obesity in adults, and then lead to diseases such as hypertension, coronary heart disease and diabetes. At present, these diseases have shown a trend of younger age.

2. Myopia. 1998, primary and secondary school students in China ranked fourth in the world for myopia; 1999, China has jumped to the second place in the world, second only to Japanese. In cities, the myopia rate remains high and continues to grow, while in rural areas, the myopia rate has obviously increased. Heavy schoolwork burden and long eye use time are the main reasons for children's myopia. And the occurrence of myopia is ahead of schedule. In the past, the focus of preventing myopia was after 9 years old. Now parents and schools should start to prevent myopia in kindergarten and primary school. Parents should avoid letting their children use their eyes too much at home. Watching TV, playing video games and watching CDs for too long will be harmful to their eyes.

3. Dental caries. Compared with the world level, the incidence of dental caries among primary and secondary school students in China is not high, but the problem of dental caries not being repaired in time is outstanding. Some children break their permanent teeth when they are very young. If there is tooth decay, it should be repaired in time, even the deciduous teeth, because too many deciduous teeth fall off, which will affect the arrangement of permanent teeth after they grow out.

4, anemia. Anemia is always similar to malnutrition of urban children. This anemia is not due to lack of food, but to lack of eating habits and nutrition knowledge. For example, some parents may not know that copying iron pots can invisibly add a lot of iron to their children. Like drinking orange juice before eating? Eating tomatoes can promote the absorption of iron; Drinking tea after meals is not conducive to the absorption of iron. In addition, although milk and eggs contain iron, it is difficult to absorb it, while iron in lean meat and pig liver is easy to absorb.

5. Mental health problems. At present, primary and secondary school students have psychological problems such as excessive shyness, cowardice, violent tendency, anxiety, depression, etc., especially when faced with the pressure of further education, employment, puppy love and so on. Experts predict that the occurrence of psychological problems of primary and secondary school students will be on the rise in the future. Therefore, society, teachers and parents should pay full attention to this problem.
