Insights

New height velocity percentiles were developed for Indian children aged 5-17 years. These charts detail growth patterns and peak height velocity ages for boys and girls, aiding in pediatric growth assessment.

Area of Science:

  • Pediatric Endocrinology
  • Human Growth and Development
  • Biostatistics

Background:

  • Accurate assessment of child growth is crucial for identifying potential health issues.
  • Existing growth charts may not fully represent diverse populations like affluent Indian children.
  • Understanding height velocity patterns is key to monitoring normal development.

Purpose of the Study:

  • To establish age- and gender-specific height velocity percentiles for Indian children aged 5 to 17 years.
  • To determine the magnitude and age of peak height velocity in this population.
  • To provide a reference tool for clinicians assessing growth in Indian children.

Main Methods:

  • A mixed-longitudinal study was conducted involving 2949 affluent children (1681 boys) in Pune and Delhi.
  • Annual height and weight measurements were collected from 2007 to 2013, yielding 13,214 height velocity measurements.
  • Height velocity percentiles (3rd-97th) were calculated using the LMS method.

Main Results:

  • Age- and gender-specific height velocity percentiles were successfully generated.
  • Girls reached peak height velocity around 10.5 years (median 6.6 cm/year), while boys peaked later at 13.5 years (median 6.8 cm/year).
  • Growth velocity showed distinct patterns of decline after the pubertal growth spurt in both genders.

Conclusions:

  • The study successfully constructed height velocity percentiles for urban Indian children aged 5-17 years.
  • These percentiles serve as a valuable reference for evaluating growth trajectories in this demographic.
  • The findings highlight gender-specific differences in the timing and magnitude of peak height velocity.

Percentile

A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile.

5-Number Summary

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Average Velocity01:12

Average Velocity

To calculate the other physical quantities in kinematics, we must introduce the time variable. The time variable allows us not only to state the position of the object during its motion, but also how fast it is moving. The speed at which an object is moving is given by the rate at which the position changes with time. For each position xi, we assign a particular time ti. If the details of the motion at each instant are not important, the rate is usually expressed as the average velocity. This...

Instantaneous Velocity - II01:10

Instantaneous Velocity - II

Instantaneous velocity is the quantity that measures how fast an object is moving along its path. In other words, the instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of displacement with respect to time. Like average velocity, the instantaneous velocity is a vector with the dimensions of length per unit time. Instantaneous velocity can have both positive and negative values. The instantaneous velocity can be...

Escape Velocity01:26

Escape Velocity

The escape velocity of an object is defined as the minimum initial velocity that it requires to escape the surface of another object to which it is gravitationally bound and never to return. For example, what would be the minimum velocity at which a satellite should be launched from the Earth's surface such that it just escapes the Earth's gravitational field?
To calculate the escape velocity, it is assumed that no energy is lost to any frictional forces. In practice, a satellite...

Velocity of an Object01:18

Velocity of an Object

Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...
