VLBW individuals had a higher mean systolic blood pressure (SBP) than normal birth weight (NBW) control individuals (114 +/− 11 versus 112 +/− 13 mm Hg; ). DBP did not differ between groups. The rates of hypertension did not differ significantly between the groups.
The prevalence of hypertension is higher in individuals who were born preterm when compared with the general population. Birth weight SDS and gestational age both did not affect the risk for hypertension.
There is an inverse correlation between high nighttime SBP SDS and birth weight. Lightness for date was discovered as a major predictor of both nocturnal and daytime SBP SDS. Nocturnal SBP SDS was closely correlated with 24 h HR SDS. 24 h HR SDS was elevated in nondippers. Preterms have increased nocturnal SBP resulting in greater frequency of nondippers.
Obese low birth weight subjects had the highest systolic BP values over the 24 hours, whereas the nonobese subjects in the absence of low BW had the lowest values. No interaction existed between obesity and low birth weight in the office or ambulatory systolic blood pressure.
50 very premature individuals <32 weeks of gestation (21 SGA, 29 AGA)
SGA had lower weight and height than AGA.there were No differences in BMI were found. In SGA more mothers had hypertension during pregnancy. Men had significantly higher SBP and lower HR. AGA–higher daytime SBP, baseline SBP, SBP load. SGA versus AGA. There were no differences in SBP, DBP, HF, and MAP loads. Newborns born very prematurely have higher SBPs, but IUGR has no effect on it.
The primary predictors of increased systolic blood pressure were weight gain velocity between birth and 36 months, pre-eclampsia, nonwhite race, and male gender. Predictors of diastolic blood pressure were weight gain velocity between birth and 36 months, brain injury, and male gender.
Systolic blood pressure values were significantly lower in the IUGR group compared to the controls. There was no difference in diastolic blood pressure values. In the IUGR group, systolic blood pressure correlated significantly with current weight and body mass index, and diastolic blood pressure with weight gain between age 2 and 4 years. None of the blood pressure values correlated with birth weight.
Hypertension was diagnosed in 10.3% of patient with ELBW. In control group hypertension was present in 5.2% cases but the difference was not significant. Statistically significant differences within night-time mean blood pressure, night-time blood pressure dipping, and mean systolic and diastolic BP load were detected
