The MAGIC Foundation India, affiliated to The MAGIC Foundation, USA, was set up to spread the awareness of various children’s growth disorders, across India. This website is intended to provide general educational information and to help users more easily access information about children’s growth disorders.
Children’s Growth – Is it important?
A child’s growth pattern is a major sign of his or her overall health!
If you do not currently have a diagnosis for your child, this is a good starting point to help you understand the facts about children’s growth. It is a home page of sorts. We will take you step by step through the learning process. We are parents who have been through this and are here to help you! Please do note that your child need not have a condition that impacts normal growth, but losing time by ignoring your concern is unnecessary. We want you to be equipped with some basic knowledge of what is normal growth in children, what can impact normal growth and when you might need to show your child to a Paediatric Endocrinologist.
What is normal growth?
Children’s growth (how much they grow each year) is crucial information. What is considered normal growth is children who are growing at least 2 1/2 inches each year after the age of 2.5 and before puberty. If your child is NOT growing the minimum of 2 1/2 inches each year after the age of 2 and a half, or he/she is growing much faster than their same age friends… these growth abnormalities can be caused by many things.
So the first thing to do is to make an appointment with your child’s medical professional who can accurately measure your child to see where he or she is on the normal or average areas of a growth chart.

What length of time is needed so see my child’s growth pattern?
The more recorded measurements you have the better! Seeing a “pattern” of growth over several years helps your medical professionals understand how your child has progressed over time. Has he or she been consistent? Are they falling further behind other children their age? Or are they much too advanced for their age? All these are serious matters for Paediatric Endocrinologists (growth specialists). Most specialists require at least 12 months of accurate measurements to establish a growth pattern. The more knowledgable you are and the more you yourself can track your child’s growth, the better are the chances that you do not miss something which is crucial.
What do percentiles mean?
Percentiles are the most commonly used markers to determine the size and growth patterns for children. Percentiles rank a child by showing what percent of kids would be smaller or taller than your child. If your child is in the 5th percentile, 95 out of 100 children the same sex and age, would be taller than your child. If you child is in the 70th percentile, he or she is taller than 70 out of 100 children the same age and sex.
Keep in mind that your child’s percentile doesn’t necessarily indicate how well they are growing. A child at the 5th percentile can be growing just as well as a child at the 95th percentile. It is more important to look at your child’s growth over time. If he/she has always been at the 5th percentile, then he/she is likely growing normally. It would be concerning if your child had previously been at the 50th or 75th percentile and had now fallen down to the 25th or lower percentile.
It is not uncommon for children under the age of 2 to change percentiles. However, after the age of 2.5 to 3 years, children should follow their growth curves fairly closely. Again, discuss any concerns with your Paediatrician.
Keep in mind that many factors influence how children grow, including their genetic potential (how tall their parents and other family members are), underlying medical problems (such as congenital heart disease, kidney disease, syndromes, etc.), and their overall nutrition plays a big role in every child’s growth and development.
If you are concerned about your child’s height or weight, talk with your Paediatrician. Continue to watch the growth annually (or more frequently if you see your child falling below a normal pattern). It is also important to make sure your child is not crossing percentiles in an upward swing because this too can represent a problem called precocious puberty.
What Causes Children to Grow Poorly?
Underlying Conditions of Children’s Growth Abnormalities
It is often said that maintaining a normal growth pattern is a good indicator of a child’s overall good health. Failure to grow at least 2 1/2 inches each year can be natures early warning sign that something underlying (unseen) is abnormal and needs medical evaluation. Growth is influenced by many factors such as heredity, genetic or congenital, illness and medications, nutrition, hormones, and psychosocial environment. Measurements of growth-height and weight are a very inexpensive service that should be offered by all health care providers rendering care to children. Additionally it is also important that these be done correctly and included as a part of sick visits as well as routine check-ups.
Normal height growth rates vary according to age. Children during the first year of life should grow 7-10 inches. During the second year growth slows to an average of 5 inches /year. During the third year growth averages 3 inches/year. From age 4 years until puberty, growth should be at least 2 inches/year. Pubertal changes prompt a growth spurt of 2 ½ to 4 ½ inches/year for girls usually starting by 10 years. However, boys experience both puberty and this growth spurt later, usually starting by 12 years and averaging 3 – 5 inches/year. After pubertal changes are completed and bone ends fuse, no further growth is possible.
1. Heredity: Children are a reflection of their parents growth patterns and height. Parents who were late bloomers and experienced slow growth and late pubertal development may see the same pattern in their children. The final height these children achieve is usually normal. Parents who have short stature usually have children whose adult height potential is in the shorter range. Conversely tall parents usually have tall children. As a general rule, a child’s potential adult height ranges between the average of the parents heights toward that of the parent who is the same sex as the child. Do note, however, that short stature in your child need not be overlooked if someone in the broader family circle is short. Do take a deeper look as you could lose time by ignoring your concerns. Sometimes checking with a Paediatric Endocrinologist can only reassure you and help by taking away any uncertainties.
2. Congenital: (those present at birth) causes for growth failure include intrauterine growth retardation, skeletal abnormalities and chromosome changes. Intrauterine growth retardation may result from maternal infections, smoking or alcohol/drug use while pregnant. Skeletal causes, such as short limb dwarfism, result from abnormal production of new bone and cartilage. These children usually have unusual trunk /limb proportions. Chromosomal variations such as Turner syndrome can cause short stature in girls, as can Down’s Syndrome.
3. Illnesses and Medications: Conditions which are considered chronic can reduce growth because they interfere with the body’s ability to use nutrients properly. Diseases which involve the kidneys, digestive tract, heart or lungs are examples of such conditions that may influence growth. Some medications that are used in large doses or for long periods of time may affect growth. If you are concerned about the effects of medications on a regular basis, you should discuss this with the physician who prescribed them.
4. Nutritional: problems can influence growth in two ways. More commonly the problem is a poor diet with inadequate nutrients, a restrictive diet of any kind, not enough calories or the wrong food groups. Secondly, diseases that interfere with the absorption of food from the bowel will prevent the body from using those nutrients for growth. In these cases symptoms may include nausea, vomiting, excessive gas, diarrhoea or constipation, poor weight gain or being underweight for height. After diagnosis, these problems usually improve with a special diet and or medications. With proper correction of these disorders, growth will also improve.
5. Psycho-social: Situations where a child’s home life is disrupted or unhappy, or where there is a lack of love, consistency or of emotional support, experience severe stress. This stress can precipitate growth failure. Children’s growth failure from this cause resumes when the problems and stress are gone.
6. Hormones: are produced in several glands in the body. After being released from the glands into the blood, the hormones have their effects on many different locations. The most common ones that affect growth are discussed next.
There are also other signs that indicate excessive cortisol such as muscle wasting and weakness, weight gain, easy bruising and thinning of the skin.
Treatment depends on the cause of the problem.
Children who are above the 95% in height or are growing unusually fast for their age may need to be evaluated by their physician. Most commonly, tall children come from tall families, are growing at the normal rate for age and show no signs of ill health. For those children in whom this is not the case, a physical examination and history may reveal the cause. Causes of rapid growth that may be abnormal include excessive growth hormone production, some congenital growth hormone production, some congenital genetic conditions or early puberty. Signals of these problems may include unusual body proportions, breast growth, enlargement of the genitals and axillary and pubic hair growth.
What Can You Do?
All children should have records of growth kept with measurements every 3-6 months for infants and yearly for children over 2 years of age. This is usually done at your child’s doctors office but you can keep your own records at home.
The best height measurement is done by having the child stand in bare feet against a wall without a baseboard with knees straight, and hips and shoulders touching the wall. Head would be level facing straight ahead. Using a flat object held against the top of the head and touching the wall, you can mark the height of the wall and measure it. Use this method at home and you can suggest that your doctor’s office do the same. This can be done with a device called a Stadiometer and is more accurate than the measuring device attached to upright scales. Children under 2 years should be measured lying on their backs on a flat surface with a measuring device that has adjustable ends. Each end of the measuring device should fit against the top of the head and soles of feet with legs extended. It is acceptable to see a decrease in height when switching from lying to standing measurements (approximately ½ – 1 inch).
Ask your child’s doctor to record the measurements on a growth chart. These charts have the normal ranges for U. S. children for height and weight for each age and sex and are divided into percentile patterns. For example, if your child is on the 10th percentile (%), he/she is taller than 10 percent of U.S. children of the same age and sex and shorter than the remaining 90%. The usual range is between the 5 – 95%.
If your child is below the 5% or above the 95% or if your child is not in the appropriate range based on his/her potential from the parents heights, your doctor should be concerned and may order other tests. Also, a growth rate that has previously been following along a certain % line and begins to move away either up or down toward another % curve may be cause for more investigation. Typically after age 2 years, a child establishes a set growth pattern along one of the % curves and follows it until growth is completed. Growing away from this percentile may signal a health problem.

Congenital Adrenal Hyperplasia
Congenital Adrenal Hyperplasia is an autosomal recessive genetic disorder, which means that it affects males and females in equal numbers, and that it requires both parents to pass on a gene in order for it to manifest as a disease. For a child to be born with any form of CAH, both parents must carry a gene for the disorder.
Growth Hormone Deficiency
Growth hormone (GH) is a protein made by the pituitary gland and released into the blood in brief pulses. The major way that GH promotes growth is by increasing levels of the hormone, insulin-like growth factor-1 (IGF-1), and its carrier protein, IGF binding protein-3 (IGFBP-3), in the blood.
Optic Nerve Hypoplasia
A child with the Syndrome of Optic Nerve Hypoplasia, also known as Septo Optic Dysplasia or DeMorsiers Syndrome, has under-developed optic nerves. The optic nerves carry messages from the eye to the brain. ONH is the single leading cause of blindness in infants and toddlers.
Russell Silver Syndrome
Russell-Silver syndrome (or Silver-Russell syndrome) is a rare genetic disorder characterized by delayed growth in-utero (IUGR) that spares head growth (meaning the newborn has a head size that is large for his body) and ongoing postnatal growth failure.
Small for Gestational Age
SGA (small for gestational age) generally describes any infant whose birth weight and/or birth length was less than the 3rd percentile, adjusted for prematurity (gestational age). Between 3% and 10% of live births each year are diagnosed as SGA.
Turner’s Syndrome occurs in 1 in 2,500 live female births. Approximately 98% of pregnancies with Turner’s Syndrome abort spontaneously and approximately 10% of fetuses from pregnancies that have spontaneously aborted have Turner’s Syndrome.
