[Selected birth outcomes as prognostic determinants of hypertension in children].
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.


OBJECTIVE
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.


CONCLUSIONS
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.
