Insights
Low birth weight, length, Apgar scores, and prematurity do not appear to influence childhood hypertension. Further research is needed to understand risk factors for pediatric hypertension.
Area of Science:
- Pediatrics
- Cardiology
- Epidemiology
Context:
- Childhood hypertension affects 5-15% of children.
- Newborn physical development and maturity are increasingly recognized as factors in primary hypertension.
Purpose:
- To assess the impact of low birth weight, low birth length, low Apgar score, and prematurity on the development of childhood hypertension.
Summary:
- This retrospective study analyzed 197 children with primary hypertension and 119 controls.
- Male sex, overweight, and family history of hypertension were significant risk factors.
- Low birth weight, low birth length, low Apgar score, and prematurity did not show a significant association with primary hypertension.
Impact:
- The findings challenge the established role of certain perinatal factors in pediatric hypertension.
- Suggests the need for broader epidemiological surveys to identify key risk factors in diverse pediatric populations.
Background:
About 5-15% of children suffer from hypertension. The influence of maturity and the physical development of newborns on primary hypertension has been recently underlined.
Aim:
The aim of the study was to estimate the importance of low birth weight (< 10 percentiles--2500 g), low birth length (< 10 percentiles--50 cm), low Apgar score (< 4 points), prematurity (< 37 Hbd) in the developmental of hypertension in children.
Methods:
The project was conducted retrospectively in a group of 197 children with primary hypertension (aged 15.4 +/- 1.9) and 119 healthy children (aged 12.9 +/- 3.1) as the control group. The statistical analysis was performed with Epilnfo 6.0 procedures.
Results:
Male sex, overweight and family history of hypertension increased the risk of hypertension in a statistically significant way and the adequate estimated odds ratios were: OR = 3.69 (95% CI: 2.20-6.19), OR = 22.76 (95% CI: 6.61-94.12), OR = 21.87 (95% CI: 6.27-91.1). No influence of low birth weight, low birth length, low Apgar score and prematurity on primary hypertension was observed.
Conclusion:
The results suggest that the role of low birth weight, low birth length, low Apgar score and prematurity in the development of hypertension in children is arguable. It also suggests the necessity to conduct epidemiologic surveys in more frequent groups of children.

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.
