Insights

This study found that 9.4% of school children aged 12-16 had hypertension. Higher weight, height, and BMI were associated with elevated blood pressure, highlighting the need for regular screening in children.

Area of Science:

  • Pediatrics
  • Cardiovascular Health
  • Public Health

Background:

  • Hypertension affects approximately one billion people globally and is a significant risk factor for cardiovascular diseases.
  • Preventable risk factors contribute to hypertension development, making early identification in children crucial for preventing complications.
  • This study focuses on determining blood pressure percentiles and their association with anthropometric variables in school-aged children.

Purpose of the Study:

  • To determine the percentile distribution of systolic and diastolic blood pressure in school children.
  • To investigate the association between blood pressure and anthropometric variables (weight, height, BMI) in this age group.

Main Methods:

  • A cross-sectional study involving 701 school children aged 12-16 years in Aligarh, selected via stratified random sampling.
  • Standardized techniques were used to measure blood pressure, weight, and height; Body Mass Index (BMI) was calculated using the Quetelet index.
  • Statistical analysis included mean, standard deviation, chi-square, and correlation coefficient using SPSS 12 software. Hypertension was defined as blood pressure above the 95th percentile.

Main Results:

  • The overall prevalence of hypertension was 9.4% (66 out of 701 children), with 9.36% in boys and 9.46% in girls.
  • Mean systolic and diastolic blood pressure increased with higher ranges of weight, height, and BMI.
  • A positive correlation was observed between children's blood pressure and anthropometric characteristics.

Conclusions:

  • Regular blood pressure screening in children is recommended to detect hypertension prevalence early.
  • Early detection allows for timely initiation of remedial measures to prevent serious complications.
  • Findings underscore the importance of monitoring anthropometric variables in relation to blood pressure in pediatric populations.

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 diastolic...

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...

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

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...
