Abstract

There have been research trials analyzing the impact of prematurity on the prevalence of hypertension, however the prospective, long-time observation is uncommon. The aim of this study was to evaluate the prevalence of hypertension at the age of 7 and 11 years of regional cohort of preterms with birth weight ≤1000g.

The study included 67 children with birth weight ≤1000g born in Malopolska. The control group consisted of 38 children born at term, matched for age. Each child underwent 24-hour ambulatory blood pressure measurement twice – at the age of 7 and 11 years. The presence of hypertension based on two definitions: 1) Mean Arterial Pressure ≥95 percentile for gender and height; 2) number of individual measurements ≥95 percentile for gender, age and height >25% was estimated.

At the age of 7 years preterm infants had significantly higher incidence of hypertension, defined on the basis of MAP (15%vs.0%; p<0.015), and on the percent of individual measurements (56%vs.33%, p<0.036). After taking into account the group of patients who received anti-HT treatment after first part of study, the incidence of hypertension at the age of 11 based on MAP was 19%vs.10% and based on individual measurements was 36,5%vs.24% (the differences are not statistically significant). In both time points a higher mean heart rate in the group of preterms was found (7 years of age: 93vs.87/min., p<0.001; 11 years of age 87vs.83/min, p=0.039).

Children born prematurely are predisposed to hypertension in later life. Persistence of increased heart rate in former preterms was shown.
