What growth and development indicators are used to evaluate?
It is suggested to use age-specific height, age-specific weight and age-specific body mass index (body mass index) to evaluate growth and development. Among them, the age-specific body mass index (BMI) is usually the standard index used to judge children's obesity.
Where: body mass index = weight (kg)/(square of height (m)).
What kind of scoring method is used?
The score of height and weight usually includes z score and percentile. At present, Z-scoring method is widely used in the world, and Z-scoring method is recommended.
Z-score method, also called standard deviation (SD) ratio method, first determines an intermediate value (0SD), and then evaluates the calculated standard deviation from the intermediate value.
How to evaluate?
It is suggested to combine "current measurement point evaluation" and "drawing growth curve evaluation" for comprehensive evaluation. The fluctuation range of the height of boys and girls is listed in detail.

The baby's height is almost in the above range. Generally no problem. If it grows too fast, it is easy to lack calcium. If there is too much difference, it is recommended to check it. Children generally have no problem as long as their nutrition is balanced! Do parents know how to evaluate their children's height and weight? I hope I can help you.
