Insights

This study establishes age- and height-specific blood pressure percentiles for children and adolescents in Yazd, Iran. These findings are crucial for identifying pediatric hypertension and improving cardiovascular health in this population.

Area of Science:

  • Pediatrics
  • Cardiovascular Health
  • Public Health

Background:

  • Pediatric hypertension is a significant contributor to illness and death in young people.
  • Accurate diagnostic criteria are essential for early detection and management.
  • The percentile rank approach is a key method for defining hypertension in pediatric populations.

Purpose of the Study:

  • To establish age- and height-specific blood pressure percentiles for children and adolescents.
  • To define hypertension using the 95th percentile threshold.
  • To provide clinical reference data for pediatric hypertension in Yazd, Iran.

Main Methods:

  • Utilized data from the Iranian Children and Adolescents' Psychiatric Disorders (IRCAP) survey.
  • Focused on a sample of 1,035 children and adolescents aged 6-18 years in Yazd province.
  • Employed random cluster sampling to select participants.

Main Results:

  • Analyzed data from 456 males (44.1%) and 579 females (55.9%).
  • Mean age was 11.2±3.8 years, with mean height of 146±20.0 cm.
  • Evaluated blood pressure distributions and determined specific percentiles.

Conclusions:

  • Determined age- and height-specific 50th, 90th, 95th, and 99th percentiles for systolic and diastolic blood pressure.
  • Utilized 10-cm height intervals for precise percentile calculation.
  • Provided essential data for identifying and managing pediatric hypertension in the study region.

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...

Special considerations while measuring blood pressure01:28

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Sites for measruring blood pressure01:21

Sites for measruring blood pressure

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.
