There are generally three ways to calculate the height and weight of boys. A. It is generally believed that the weight standard for men is height (cm) - 105 = weight standard (KG). B. The method used by the World Health Organization to calculate weight standards. Men: (height cm-80) * 70% = weight standard. Weight standards that are 10% positive or negative are normal weight. Weight standards that are 10%-20% positive or negative are too heavy or too light. Weight standards that are more than 20% positive or negative are obesity or underweight. C. Another new type of standard weight calculation, weight standard = height (m) * height (m) * 22, overload calculation method: overload% = {(specific weight - ideal weight) / (ideal weight)} x 100%. The correspondence table between children's height and weight has different standards at different stages of development. The actual standards are as follows: 1. Weight: 1-6 months weight (kg) = birth weight + 0.7; 7-12 months weight (kg) = 6 months + 0.25; Generally, the weight at 1 year old is about 15kg, and the height is about 75cm. The weight from 2 years old to before puberty (kg) = age + 2 + 7; 2. Height: It is not accurate to measure the standing position of children under 3 years old. They should be accurately measured in a supine position, which is called body length. The average body length of a newborn is 50cm. The accurate standing position measurement of children over 3 years old is called height. The height estimation formula for 2-12 years old is: Height (cm) = Age (years) Periodontal 7 77; Children's height and weight are related to genetic inheritance, race, endocrine system, nutrition, exercise and diseases. The growth and development of children can be comprehensively assessed based on their height and weight. Obvious body shape abnormalities are often caused by etiologies such as rickets, severe malnutrition, and growth hormone deficiency, and need to be treated promptly. In addition, spring is an important season for children's growth and development. At this time, they need to supplement with sufficient fish, shrimp, eggs and other protein foods to promote their growth and development. |
