Physical Development
PHYSICAL DEVELOPMENT
The term "physical development of children" understand the dynamic process of growth (increase of length, mass, body parts) at different periods of childhood. On the physical development of children is influenced by many factors, which sometimes makes it extremely difficult to identify the reasons for its violation. The main criteria of physical development include weight and body length, head circumference and chest, the proportions of the body (physique, posture). Key figures and formulas used for approximate estimation of the physical development of the child are given in Table 2-2.

Indicators and formula development
Fruit
Fetal body weight in 30 weeks - 1300 g; for each additional week is added 200 grams, each consuming 100 grams of the missing body length at 25-40 weeks the fetus: the period of gestation in weeks 10 cm Head circumference fetus at 34 weeks - 32 cm; each week thereafter add 0,5 cm, each missing consume 1 cm
Circumference of the chest in the 25-40 week fetus: gestational age in weeks - 7 cm
Newborn
Body mass 3300-3500 g body length 51-53 cm Head circumference 35-36 cm chest circumference of 33-34 cm
The physiological loss of body weight for 3-5-th day of life is 3-6% body weight is restored to the 7 th and 10 th day of life
1 month
Weight gain (calculated from birth weight) - 600 g
The increase in body length of 3-4 cm increase in head circumference at 1,5-2 cm increase in circumference of chest at 2 cm
3 months
The average weight gain - 700 g per month increase in body length - 3 cm
Increased head circumference of 40 cm (monthly gain 1,5-2 cm) and circumference of the chest to the same size
6 months
The average weight gain - 700 g increase in body length per month (after 3 months) at 2,5 cm increase in head circumference to 43 cm (monthly gain after 3 months - 1 cm)
1 year
The average weight gain (after 6 months) - 400-600 g body weight to 1 year -
