Insights

This study compared height growth centiles and curves in Indian children using GAMLSS and SITAR methods. SITAR effectively summarized individual growth patterns, while GAMLSS showed population height distributions.

Area of Science:

  • Pediatric endocrinology
  • Biostatistics
  • Human growth and development

Background:

  • Growth centiles and curves are standard methods for presenting child anthropometry.
  • These methods differ in data requirements, analytical approaches, biological parameters, and interpretation.

Purpose of the Study:

  • To fit and compare height growth centiles and curves in Indian children.
  • To evaluate the utility of GAMLSS and SITAR models for analyzing pediatric growth data.

Main Methods:

  • Longitudinal height data from 1468 Indian children (aged 6-18 years) were analyzed.
  • Generalised Additive Models for Location Scale and Shape (GAMLSS) were used for growth centiles.
  • SuperImposition by Rotation and Translation (SITAR) was employed for growth curves.

Main Results:

  • SITAR explained over 98% of height variance in boys and girls, accurately identifying peak height velocity.
  • GAMLSS (Box-Cox Cole Green model) also identified pubertal growth spurts, but produced shallower centiles compared to SITAR.
  • Boys exhibited a mid-growth spurt around age 8 years.

Conclusions:

  • GAMLSS provides population-level height distributions by age and sex.
  • SITAR offers a parsimonious summary of individual child height growth patterns.
  • Both GAMLSS and SITAR yield distinct and valuable insights into child growth.

Variation: Normal Distribution, Range, and Standard Deviation

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Applications of Normal Distribution01:22

Applications of Normal Distribution

The normal distribution is a useful statistical tool. One of its practical applications is determining the door height after considering the normal distribution of heights of persons, such that many can pass through it easily without striking their heads. The normal distribution can also determine the probability of a person having a height less than a specific height.
The heights of 15 to 18-year-old males from Chile from 1984 to 1985 followed a normal distribution. The mean height is 172.36...

Polygenic Traits01:18

Polygenic Traits

When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Microbial Growth Measurement: Indirect Methods

Estimating microbial growth is essential for understanding population dynamics and environmental adaptations. Indirect methods provide valuable insights by measuring parameters such as turbidity, metabolic activity, and biomass, enabling efficient and reproducible assessments.During exponential growth, microbial cells scatter light proportionally to their biomass, a principle used in turbidity measurements. About one million cells per milliliter produce detectable scattering, which a...

Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
