Background: Epidemiological studies have found that intrauterine growth retardation (IUGR) is closely related to hypertension and is associated with a reduced number of nephrons that may be a predisposing factor for the development of hypertension.

Objectives: To determine whether blood pressure levels of children with a history of IUGR are higher than those of children without IUGR.

Methods: Diastolic, systolic and mean arterial blood pressure levels were measured in 64 children aged 8–12 years old with a history of IUGR (mean birth weight 1780
± 422 g) and compared with 64 age and gender-matched controls who had a normal birth weight (mean 3134 ±  594 g).

Results: Contrary to previous reports, systolic blood pressure values were significantly lower in the IUGR group compared to the controls (91.6
±11.3 vs. 96.6 ±13.9, P = 0.027). There was no difference in diastolic blood pressure values. In the IUGR group, systolic blood pressure correlated significantly with current weight (P < 0.01) and body mass index (P < 0.05), and diastolic blood pressure with weight gain between age 2 and 4 years (P < 0.05). None of the blood pressure values correlated with birth weight.

Conclusions: Children born with IUGR have lower systolic blood pressure levels than matched controls at age 8–12 years. These data indicate that postnatal weight gain in this group has a greater impact on systolic blood pressure than birth weight.

Background: Low birth weight has been shown to be strongly related to hypertension in adult life.

Objective: To determine whether blood pressure is higher in children with intruterine growth retardation than in control subjects.

Methods: Blood pressure was measured in 58 children aged 4-6 years with IUGR and in 58 age-matched controls. The control children, whose birth weight was appropriate for gestational age, were also matched for gestational age.

Results: The children with IUGR had significantly higher mean values of systolic (p<0.05) and diastolic blood pressures (p<0.05) and mean arterial pressure (p<0.05). Significant differences in blood pressure values were found between preterm IUGR (n=21) and preterm controls (p<0.05).

Conclusion: These data indicate that children with IUGR may be at higher risk of hypertension already in childhood.
