Indian children

Area of Science:

  • Pediatric Growth and Development
  • Human Nutrition
  • Public Health

Background:

  • Assessing child growth is crucial for identifying nutritional status and health trends.
  • Existing growth standards, like European and National Center for Health Statistics (NCHS), are widely used.
  • Understanding regional variations in child growth is essential for targeted health interventions.

Purpose of the Study:

  • To establish growth percentiles for urban affluent Indian children.
  • To compare Indian children's growth with established European and American standards.
  • To identify potential factors influencing observed growth differences.

Main Methods:

  • Collected anthropometric data (height, weight, head, chest, mid-arm circumferences) from urban affluent children across seven Indian centers.
  • Utilized a smoothed cubic spline least squares method for calculating pooled data percentiles.
  • Sample size: 200 observations per age and sex point (except 18 and 72 months).

Main Results:

  • Pooled data for Indian children showed lower values compared to European and NCHS (American) standards.
  • Children from Ludhiana exhibited growth patterns closer to the NCHS standards.
  • Observed growth differences may be attributed to lower growth velocity in Indian children during the first 18 months.

Conclusions:

  • Urban affluent Indian children in this study demonstrate distinct growth patterns compared to Western standards.
  • Ludhiana children's growth more closely aligns with American standards, suggesting regional variations within India.
  • Slower early growth velocity (first 18 months) might explain the divergence from American growth trajectories.

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, such as differences...
Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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)...
Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
Physical Growth During Infancy and Toddlerhood01:18

Physical Growth During Infancy and Toddlerhood

Physical growth is especially rapid during the first three years of life, with the greatest rate in the first few months after birth. Although children continue to gain height and weight throughout infancy and toddlerhood, the rate of growth gradually slows during the second and third years. At most ages, boys are typically slightly taller and heavier than girls, reflecting a common pattern of early physical development.Changes in Body ProportionsAs infants become toddlers, their body...
