Excess fat is not the same

1. The law of growth in height in children

Is the first year of the fastest-growing. General full-term infants at birth to an average height of 50 cm, 25 cm increase in the first year, 6 months for the first time in particular, growth. The second year the growth rate slowed down significantly, an increase of about 11 cm. 2-year-old to adolescence (about 10 years old), the annual growth rate of 6 to 7 centimeters.

2 to 10-year-old child is generally available to the average projection formula:

Height (cm) = age × 5 + 75 (cm)

Standing by a significant genetic influence, in addition, the nutritional status and living conditions, sunny air, disease, endocrinology, and so can be affected in varying degrees of growth in height.

2. The law of weight gain in children

The normal law is younger, the faster the weight gain. 1 year old with body weight in children is increasing the fastest stage of life, 1-year increase of 7 kg: 1 to 3-year-old child for the period, the growth rate of body weight in children than in infancy (age 1 month to) slow; after the 3-year-old to 10 years old, weight The average annual increase of about 2 kg.

3. Height and weight boys and girls change

And in the same age children in the past, today's children grow, early development. Experts on contemporary children's height and weight standards for a large-scale study found that a number of laws: 9-year-old before the boy's weight, height more than girls; 10-year-old, tall girls than boys start; 11 13-year-old girl's height, weight indicators than boys; 14-year-old, tall boys than girls, but the weight is still slightly higher than girls, boys; 15-year-old, the boy's weight, height and more than girls.

4.2 to 12-year-old child's weight calculation

2 to 12-year-old child weighs more or less standard formula that can be used to express:

Weight (kg) = chronological age × 2 + 8

The formula is only average, in fact the same age children will be the weight difference. Such as: emphasis on girls than boys (with the exception of the early youth), high body weight of children more heavily, sawed-off more light on. In short, as long as up and down not far from the average, that can be normal.

5. Overweight and obesity differ

Overweight referred to as "overweight" refers to the actual measured their body weight than the standard weight of 10% and 20%; more than 20% compared to the "obese." Overweight children can easily develop into fat should be as soon as possible to take preventive measures.

Need to pay attention to situations: some children at an early age weightlifting, football, swimming, acrobatics, such as school, physical activity, high-intensity exercise, so unusually well-developed muscles, their body weight than the standard weight of more than 20%, but the amount of body fat has Normal, it is not considered obese; some children suffering from certain diseases so that the moisture retention in the body too much, if ascites or edema of lower limb, even if their weight exceeds the standard weight of 20% can not be said to be obese; some children's lives Comfort, lack of exercise, due to less activity, not energy consumption in a timely manner, resulting in excessive accumulation of fat in the body, although the weight does not exceed the standard weight of 20%, should belong to obesity.
