Growth defined as an increase in size of body, biological growth of an organism takes place through cell multiplication this morphological growth can be measured clinically

Growth : defined as an increase in size of body, biological growth of an organism takes place through cell multiplication, this morphological growth can be measured clinically

Development is the association process of differentiation of the organism, in which growing tissues and organs take on increased complexity of function(physiological motor, cognitive, affective)

Development : is the association process of differentiation of the organism, in which growing tissues and organs take on increased complexity of function(physiological, motor, cognitive, affective)

Thus, since both processes are part of one whole the combined terms growth and development form an unitary concept that indicates the quatitative and qualitative of maturational changes of an organism

Physical growth can be assessed by various anthropometric measurements

Physical growth can be assessed by various anthropometric measurements

Weight o is composed of tissues organs systems and fluid etc. o is a common and sensitive measurement of physical growth especially for evaluating present nutrient state

• is composed of tissues, organs ,systems and fluid, etc. • is a common and sensitive measurement of physical growth, especially for evaluating present nutrient state. Weight

Age Increment Increment Weight(kg (kg (kg/y) At birth 3m 36 12m 9± 333 24m 12± 632 >2y pUberty 2kg /y

Patterns of Weight Increment 1, The first growth spurt occurs in the first year of life(the increment is about 6kg). 2 Growth is not at the same rate in different age The increment of weight during the first 3 months is equal to that of the following 9 months 3. Yearly increments increase slowly until the onset of puberty
