SHORT STATURE:

• A child whose height is below the 3rd percentile for age and sex.

GROWTH FAILURE:

• Slow growth rate regardless of the stature.

• Ultimately, a slow growth rate leads to short stature.

•A Growth Chart is used to show:• A child's current height.• Growth Velocity : how fast the child is growing.

GROWTH CHARTS:

• Growth charts are a standard part of any checkup.

• They show health care providers how kids are growing compared with other

kids of the same age and gender.

DIFFERENT TYPES OF GROWTH CHARTS:

Weight-for-Age Height-for-Age

HC-for-Age

Weight-for-Height

FEMALEGROWTHCHARTS

DIFFERENT TYPES OF GROWTH CHARTS:

Weight-for-Age Height-for-Age

GROWTH CHARTS:

• Assessment:

•Short Stature: Height < 3rd percentile.

•Growth Failure:• Height crossing 2 major percentiles.

•Low growth velocity: Rate < 25th percentile.

• Short stature with normal growth rate and delayed growth spurt with eventual achievement of normal adult stature.

MID-PARENTAL HEIGHT:

• Children are usually in a percentile between their parents' height.

• The Expected Height of the child as adult lies between ± 5 cm from the Mid-parental age:

Girls:

= 2

Boys:

= [Mother’s Height + Father’s Height + 13]

[Mother’s Height + Father’s Height - 13]
