Insights

Large neck circumference (NC) in children is linked to higher blood pressure. This meta-analysis confirms NC as a predictor of elevated blood pressure and hypertension risk in pediatric populations.

Area of Science:

  • Pediatric Cardiology
  • Public Health
  • Anthropometry

Background:

  • Emerging evidence suggests a link between large neck circumference (NC) and elevated blood pressure in children and adolescents.
  • NC is an anthropometric measurement that may serve as an early indicator of cardiovascular risk.

Purpose of the Study:

  • To conduct a systematic review and meta-analysis on the association between neck circumference (NC) and blood pressure in children.
  • To evaluate NC as a potential predictor for hypertension in pediatric populations.

Main Methods:

  • Systematic review and meta-analysis of studies published up to January 2018, identified via PubMed and Scopus.
  • Inclusion of 15 studies reporting correlation coefficients between NC and blood pressure in individuals under 18 years.
  • Quantitative synthesis to determine the association between NC, systolic blood pressure (SBP), and diastolic blood pressure (DBP).

Main Results:

  • A significant positive correlation was found between NC and SBP (meta r = 0.371) and DBP (meta r = 0.245).
  • NC was positively associated with an increased risk of hypertension (OR = 1.35).
  • Higher hypertension risk associated with NC was observed in Western regions (OR = 1.55) compared to Eastern regions (OR = 1.14).

Conclusions:

  • Neck circumference is a significant predictor of elevated blood pressure in children and adolescents.
  • NC may serve as a novel, easily measurable anthropometric marker for identifying children at risk of hypertension.
  • The association between NC and hypertension risk appears stronger in Western populations.

Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Pressure01:30

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
