Women with prior preeclamptic pregnancies have an increased risk for metabolic syndrome and cardiovascular diseases. Maternal preeclampsia has been associated with elevated blood pressure (BP) in offspring during childhood. The aim of our study was to determine whether elevated BP pressure and metabolic changes, such as dyslipidemia, insulin resistance, and increased adrenal hormonal activity, are found in 12-yr-old children of preeclamptic mothers. Sixty children born after preeclamptic pregnancy (PRE) and 60 matched control subjects born after normotensive pregnancy (non-PRE) were studied at the age of 12 yr. The case-control pairs were matched for sex, gestational age (+/-1 wk), and size at birth. We measured BP and concentrations of blood glucose, serum fasting insulin, total and high density lipoprotein cholesterol, triglycerides, cortisol, dehydroepiandrosterone sulfate, and plasma epinephrine (E) and norepinephrine (NE). Low density lipoprotein cholesterol was calculated according to the Friedewald-Fredrickson formula. The PRE children had significantly higher mean systolic (116.4 vs. 113.2 mm Hg; P = 0.021) and diastolic (73.9 vs. 70.3 mm Hg; P = 0.022) BP than the non-PRE children, even when adjusted by current weight and height. At 12 yr of age, systolic BP values correlated inversely with birth weight (r = -0.459; P < 0.001) and length SD scores (r = -0.429; P = 0.001) in the PRE children. The mean concentrations of serum total, low density lipoprotein, and high density lipoprotein cholesterol; triglycerides; fasting insulin; blood glucose; serum cortisol; and dehydroepiandrosterone sulfate did not differ between the PRE and non-PRE groups. However, the mean plasma E concentration was higher in the PRE than in the non-PRE children (0.32 vs. 0.28 nmol/liter; P = 0.042), whereas the mean NE concentration did not differ between these two groups. In conclusion, 12-yr-old children born with maternal preeclampsia had elevated systolic and diastolic BPs and slightly increased E levels in the circulation. It is not known whether these changes are caused by genetic factors or by preeclampsia itself.

According to Barker's hypothesis, children born small for gestational age (SGA) are at increased risk for cardiovascular diseases in adulthood. The aim of our study was to determine whether retarded fetal growth is associated with dyslipidemia in childhood and, if so, to find predictive factors in the growth characteristics of SGA children. We studied the serum lipid concentrations of 55 SGA children and their 55 appropriate for gestational age control subjects at the age of 12 y. Growth variables were recorded at birth, 5 y, and 12 y of age. The study group consisted of all full-term SGA children born at our university hospital during a 22-mo period in 1984 -1986. Nearly half of the SGA children (47.3%) were in the highest quartile for serum total cholesterol of the appropriate for gestational age children (p ϭ 0.038). In multiple logistic regression analysis, poor catch-up growth in height (odds ratio, 13.8; 95% confidence interval, 2.0 -97.5), female sex (odds ratio, 8.1; 95% confidence interval, 1.3-48.9), and early stage of puberty (odds ratio, 7.5; 95% confidence interval, 1.2-46.5) predicted high cholesterol level in the SGA children. By the age of 5 y, 20 (36.4%) SGA children showed catch-up growth of Ն 2 SD scores in height, and 21 (38.2%) SGA children showed catch-up growth of Ն 2 SD scores in weight from birth. At the age of 12 y, the SGA children were still significantly shorter (p Ͻ 0.001) and lighter (p Ͻ 0.05) than the appropriate for gestational age children, even though their pubertal development was similarly advanced. In conclusion, to be born SGA has long-term consequences for later growth and may already influence the level of serum total cholesterol before the teens. SGA children with poor catch-up growth in height may be at the highest risk for hypercholesterolemia.

Previous studies have revealed that antemortem serum lipid values in children and young adults correlate significantly with atherosclerotic changes (1, 2). In addition, follow-up studies of children have shown that concentrations of serum total cholesterol tend to track for several years, and measurements obtained in childhood predict total and LDL cholesterol levels in adults (3-5).Findings by have led to the "fetal origins" hypothesis, which suggests that hypertension, hyperlipidemia, and non-insulin-dependent diabetes are programmed by malnutrition in utero. Low growth rate during fetal life and infancy is associated with increased rates of death caused by cardiovascular diseases in adulthood (10 -12). This association is seen in individuals born SGA rather than in those born prematurely (10). Moreover, Barker et al. (13) have reported a relationship between small abdominal circumference at birth and increased se...

Ambulatory blood pressure (ABP) monitoring offers a reliable method for determining blood pressure (BP) in children. The aim of this cohort study was to examine whether maternal preeclampsia is associated with elevated BP in an offspring. The study population consisted of 57 children born to preeclamptic mothers (PRE) and their 57 age-and sex-matched control subjects born to normotensive mothers (non-PRE). We examined the 24-h ABP at 12 y of age in the PRE and non-PRE children. Within the two groups, the association of anthropometric measures, plasma catecholamine (epinephrine [E], norepinephrine [NE]) concentrations, and ABP was examined. The PRE children had significantly higher mean 24-h systolic and diastolic ABPs than the non-PRE children. The same was true for the mean daytime and nighttime systolic and diastolic ABPs. The PRE boys had higher 24-h systolic ABP than the PRE girls. In the PRE children, high plasma E concentration and being born small for gestational age (SGA) predicted high systolic 24-h ABP in logistic regression analysis. In the non-PRE children, high current body mass index (BMI) and high plasma E concentration was associated with high systolic 24-h ABP. In conclusion, systolic and diastolic ABP values were elevated in the PRE children. High plasma E concentration and being born SGA were associated with high systolic 24-h ABP in the PRE children. Presumably maternal preeclampsia affects offspring via several mechanisms, including genetic ones and metabolic consequences of restricted intrauterine growth.
