Signs of developmental delay

Growth is a process that everyone goes through. When you reach a certain age, if everyone around you has entered this stage, but you have not yet shown such signs, parents will be more concerned about this issue. If you want your child to develop without retardation, the first thing you need to pay attention to is the diet. Development is a critical link, and requires a lot of nutrients to be absorbed, so diet is very important if you want to solve developmental delays.

No matter what the physical condition is, there will be certain symptoms. Only in this way can we discover it and find ways to solve such problems, so as to make our bodies healthier. The same principle applies to development, because only in this way can parents discover and adjust their diet. So what are the symptoms of developmental delay?

Human growth and development refers to the process of maturation from fertilized egg to adult. Growth and development are important characteristics that distinguish children from adults. Growth refers to the growth of various organs and systems in a child's body, and corresponding measurements can be used to represent the changes in their quantity; development refers to the differentiation and functional maturation of cells, tissues, and organs. Growth and development are closely related. Growth is the material basis of development. Changes in the amount of growth can reflect the maturity of the body's organs and systems to a certain extent.

Performance

1. Physical development is delayed;

2. Motor development is delayed;

3. Language development is delayed;

4. Mental retardation;

5. Psychological development is delayed, etc.

The manifestations of growth retardation are often multifaceted, mostly physical development, motor development and intellectual development, but one aspect may be prominent. If the measured values ​​of height, weight and head circumference are all low, it means that the child has a comprehensive developmental delay and you should consult a pediatrician in detail to confirm whether further examination is needed. If only one of the indicators of height, weight or head circumference is low, it means that the child may have partial developmental delay. Further examination of brain nerves or endocrine system etc. may be required to understand whether the child's physical development has been affected.

diagnosis

1. Physical growth evaluation

According to the recommendation of the former Ministry of Health, the physical growth data of children in China's nine major cities in 1995 were used as the reference population value for Chinese children. The evaluation of children's physical growth includes three aspects: development level, growth rate and symmetry.

(1) Developmental level: The measured value of a physical growth indicator (cross-sectional measurement) obtained at a certain age is compared with the value of a reference population to obtain the child's position in the homogeneous population, that is, the growth level of the child's physical growth indicator at this age. The result is usually expressed in grades. Growth level includes all individual physical growth indicators, such as weight, height (length), head circumference, chest circumference, upper arm circumference, etc., which can be used to evaluate individual or group children.

Some single measurements, such as bone age, represent developmental maturity and also reflect developmental level. Likewise, physical measurements can be used to represent developmental level or maturity based on age. For example, if a 2-year-old boy is 76cm tall, his height growth level is poor, and his height growth age is equivalent to that of a 1-year-old.

(2) Growth rate refers to the regular and continuous measurement (longitudinal observation) of a single physical growth indicator. The growth value of the indicator at a certain age stage is compared with the value of the reference population to obtain the growth rate of the child's physical growth indicator. The simplest and most intuitive way to express growth rate is by using a growth curve. Regular physical examinations are the key to evaluating growth rate. Children are young and grow quickly, so the intervals between regular check-ups should not be too long. The evaluation of growth rate can provide a more accurate understanding of children's growth status than the developmental level. Children with a normal growth rate have basically normal growth.

The symptoms of developmental delay are usually that when you reach a certain age, your height, physique, mental and other characteristics are different from other people of the same age. Your height has not reached the standard value for this age, and you do not have the maturity that you should have at this age. These manifestations are all signs of growth and developmental delay. So when you find such behavior, you should think about solving it.
