Insights

Children born very low birth weight (VLBW) in Thailand showed a 15.2% hypertension prevalence. Obesity at age 3 and current obesity were significantly linked to hypertension in VLBW children.

Area of Science:

  • Pediatrics
  • Cardiology
  • Public Health

Background:

  • Children born very low birth weight (VLBW) face increased hypertension risk, particularly in developing nations.
  • Limited data exists on hypertension prevalence and associated factors in VLBW children from developing countries.

Purpose of the Study:

  • To determine the prevalence of hypertension in children born VLBW in Thailand.
  • To identify perinatal and postnatal factors associated with hypertension in this cohort.

Main Methods:

  • Ambulatory blood pressure monitoring (ABPM) was conducted on 46 children (≥6 years) from a VLBW cohort.
  • Statistical analyses, including multivariate analysis, were used to identify risk factors.
  • Office blood pressure and BMI z-scores were assessed.

Main Results:

  • The prevalence of hypertension was 15.2% (7/46) in the VLBW cohort.
  • Hypertension was significantly associated with higher BMI z-scores at age 3 and current obesity (OR 34.77).
  • Masked hypertension was identified in 11.1% of children with normal office blood pressure, with office systolic blood pressure at the 85th percentile being a key predictor.

Conclusions:

  • Obesity is a significant risk factor for hypertension in children born VLBW in Thailand.
  • ABPM is crucial for detecting hypertension, including masked hypertension, in this vulnerable population.
  • Early monitoring and intervention for obesity are recommended for VLBW children to mitigate cardiovascular risks.

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Factors affecting Blood pressure01:28

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 II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

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...

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
