Insights

This study analyzed upper body segment (US) and lower body segment (LS) ratios in Indian children aged 0-18 years. The US:LS ratio changes significantly with age, reaching its lowest point in early adolescence.

Area of Science:

  • Pediatric anthropometry
  • Human growth and development
  • Body segment proportions

Background:

  • Understanding body segment proportions is crucial for assessing child growth.
  • Existing norms for the upper body segment (US) to lower body segment (LS) ratio may vary across populations.
  • Establishing population-specific data is essential for accurate clinical assessment.

Purpose of the Study:

  • To determine the upper body segment (US), lower body segment (LS), and US:LS ratio in Indian children from birth to 18 years.
  • To compare these findings with previously reported US:LS ratio norms.
  • To provide reference data for diagnosing disproportionate short stature.

Main Methods:

  • A cross-sectional observational study involving 5454 children (3158 boys) aged 0-18 years.
  • Data collected in Pune city, Western India, between December 2015 and June 2017.
  • Analysis of upper body segment (US), lower body segment (LS), and their ratio (US:LS).

Main Results:

  • The mean US:LS ratio at birth was approximately 1.45 in boys and 1.44 in girls.
  • The ratio decreased with age, reaching a nadir of 0.89 at 14 years in boys and 12 years in girls.
  • The US and LS curves intersected (US:LS=1) between 6-8 years of age, varying slightly by sex.

Conclusions:

  • This study provides normative data for US, LS, and US:LS ratios in children from Western India.
  • These data can aid in the diagnosis of disproportionate short stature.
  • The findings highlight age and sex-specific changes in body segment proportions during childhood and adolescence.

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Western Blotting01:15

Western Blotting

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Poisson's Ratio01:23

Poisson's Ratio

Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Odds Ratio01:09

Odds Ratio

The odds ratio (OR) is a statistical measure used extensively in epidemiology and research to quantify the strength of association between exposure and outcome across different groups. Unlike relative risk, which compares the probabilities of an event occurring, the odds ratio compares the odds of an event occurring in the exposed group to the odds of it occurring in the unexposed group. The odds, in this context, are calculated as the probability of the event happening divided by the...

Hazard Ratio01:12

Hazard Ratio

The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
