For both boys and girls there are two sets of charts: one for infants ages 0 to 36 months and another for ages 2 and above. Children with failure to thrive usually have a weight that is below the 3rd or 5th percentile for their age and a declining growth velocity (meaning they are not gaining weight as expected).
Peak height velocity (PHV) occurs at the average age of 11 years for girls and at the average age of 13 years for boys. [29] While there is no exact age for the culmination of bone maturity, modern research suggests a range of between 15-17 years for bone maturity in boys and 14-16 years for girls.
Boys are under a lot of societal pressure to look a certain way, Ganjian says. “Boys may feel pressure to be tall and muscular, especially in sports or certain social circles,” he says.
The 2000 CDC growth charts - a revised version of the 1977 NCHS growth charts - are the current standard tool for health care providers and offer 16 charts (8 for boys and 8 for girls), of which BMI-for-age is commonly used for aiding in the diagnoses of childhood obesity. [1]
The diagnosis of FTT relies on plotting the child's height and weight on a validated growth chart, such as the World Health Organization (WHO) growth charts [62] for children younger than two years old or the U.S. Centers for Disease Control and Prevention (CDC) growth charts [63] for patients between the ages of two and twenty years old.
