Insights

Repeated high blood pressure in children is linked to maternal gestational diabetes, obesity, family history of hypertension, and prematurity. These factors increase the risk of elevated systolic and diastolic blood pressure over time.

Area of Science:

  • Pediatrics
  • Cardiovascular Health
  • Epidemiology

Background:

  • Study on the prevalence and associated factors of repeated high blood pressure in children.
  • Utilized data from the Pelotas (Brazil) 2004 Birth Cohort.

Purpose of the Study:

  • To evaluate the prevalence of repeated high systolic (SBP) and diastolic blood pressure (DBP).
  • To identify factors associated with persistent elevated blood pressure in children at 6- and 11-year follow-ups.

Main Methods:

  • Enrolled all live births to mothers in Pelotas' urban area.
  • Transformed blood pressure (BP) values into Z-scores by sex, age, and height.
  • Defined high SBP/DBP as repeated BP Z-scores on the ≥95th percentile at two follow-ups; analyzed associations using logistic regression.

Main Results:

  • Prevalence of repeated high SBP was 1.7%, DBP was 2.3%, and both (SDBP) was 1.2%.
  • High SBP associated with males, gestational diabetes mellitus, and childhood obesity.
  • High DBP associated with females, family history of hypertension, and preterm birth (<34 weeks gestation).

Conclusions:

  • Prevalence of repeated high blood pressure was within expected population distributions.
  • Gestational diabetes mellitus, obesity, family history of hypertension, and prematurity are significant risk factors for sustained high blood pressure in children.
  • These findings highlight critical early-life factors influencing long-term cardiovascular health.

Repeated Blood Collection from Tail Vein of Non-Anesthetized Rats with a Vacuum Blood Collection System

Here, we describe a simple tail vein blood sampling method in non-anesthetized rats using a vacuum extraction tube system. This method reduces the risk of direct exposure to blood and simplifies taking multiple samples from a single venipuncture.

Repeated Blood Collection for Blood Tests in Adult Zebrafish

Repeated blood sampling is necessary and important in animal research. We developed a novel, non-lethal and reliable method for repeated blood collection from adult zebrafish, and applied this method to the study of blood biochemistry, including glucose...

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...

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...
