Essential hypertension: antecedents in children

Area of Science:

• Pediatrics
• Cardiovascular Health
• Genetics

Background:

• Essential hypertension (EH) is a significant public health concern.
• Early identification of risk factors in children is crucial for prevention.
• Genetic predisposition plays a role in the development of EH.

Purpose of the Study:

• To determine the incidence of EH in children from EH families.
• To identify potential early markers for EH in at-risk children.
• To compare metabolic and dietary factors between children with and without a family history of EH.

Main Methods:

• Prospective study design.
• Inclusion of 90 children (2-18 years) with a family history of EH (study group).
• Inclusion of 25 age-matched children from non-hypertensive families (control group).
• Measurement of diastolic blood pressure, serum cholesterol, serum triglycerides, and 24-hour urinary sodium excretion.
• Assessment of dietary intake (salt and fat).

Main Results:

• Approximately 30% of children in the study group exhibited diastolic blood pressure above the 95th percentile.
• An additional 27% of children in the study group presented with borderline hypertension.
• Significantly higher levels of serum cholesterol, serum triglycerides, and 24-hour urinary sodium excretion were found in the study group compared to controls (p < 0.05).
• Children in the study group demonstrated significantly higher salt (p < 0.001) and fat intake (P < 0.05).

Conclusions:

• Children with a family history of essential hypertension are at increased risk for developing hypertension.
• Elevated serum lipids, increased urinary sodium excretion, and higher dietary salt and fat intake are potential early markers in these at-risk children.
• Early lifestyle interventions targeting diet may be beneficial for children with a familial predisposition to hypertension.
