OBJETIVO: Analisar as evidências na literatura do efeito do peso ao nascer sobre a ocorrência de síndrome metabólica em adultos. MÉTODOS: Foram pesquisados nas bases PubMed and LILACS, no período de 1966 a maio de 2006, artigos publicados usando os seguintes descritores: "birth weight" , "birthweight" , "intra-uterine growth restriction (IUGR)", "fetal growth retardation", "metabolic syndrome", "syndrome X", "Reaven's X syndrome". Foram selecionados 224 estudos considerados elegíveis que relatavam estimativas de associação entre peso ao nascer e síndrome metabólica ou seus componentes. Desses, 11 apresentavam razões de odds e foram usados na meta-análise. RESULTADOS: Com exceção de dois estudos, os demais relataram associação inversa entre peso ao nascer e síndrome metabólica. Comparadas com pessoas de peso normal, a razão de odds do efeito combinado naquelas que nasceram com baixo peso foi de 2,53 (IC 95%: 1,57;4,08). O gráfico de funil sugere viés de publicação e o resultado permanece estatisticamente significativo mesmo em estudos com mais de 400 pessoas (efeito combinado 2,37; IC 95%: 1,15;4,90). CONCLUSÕES: Baixo peso ao nascer aumenta o risco de síndrome metabólica na idade adulta.

Group 3

Sixty-three term newborn infants with fetal growth retardation were evaluated within three days of birth. They were classified by length and head circumference. In group 1, both length and head circumference were less than the tenth percentile; in group 2, either length or head circumference was less than the tenth percentile; and in group 3, both length and head circumference were greater than the tenth percentile. Ponderal index (weight/length ratio), anterior fontanel size, and amount of epiphyseal ossification were also determined. Significantly lower birth weights and decreased ossification were found when groups 1 or 2 were compared separately with group 3. These differences were most marked when the weight/length ratio was less than 2.25. When the ponderal index was less than 2.0, epiphyseal ossification was usually absent (suggesting a chronic process). Epiphyseal ossification was positively correlated with birth weight and length but was unrelated to anterior fontanel size. Ossification was more often absent in males than in females. There was a negative (inverse) correlation between birth weight and anterior fontanel size. Follow-up of 32 of these infants at age 1 year showed marked individual variations, but there were significant differences in incremental linear growth between groups 1 and 3, a finding which supports results of animal studies showing that catch-up growth may be related to skeletal immaturity. Physical measurements at birth in the individual baby with fetal growth retardation do not reliably predict subsequent growth.

Normal Term

Intrauterine growth was assessed in a series of 128 cases. Thirty-six infants were small for gestational age, and showed the usual signs of intrauterine growth retardation (IUM). The head circumference of these infants was small, with reference to normal term babies (FT) and comparable to premature infants, appropriately sized for a gestational age (ACA) five weeks less than that of the IUM's. There were 12 neonatal deaths, three among IUM infants within 24 hours and nine in the low birth weight AGA group within 72 hours. The mothers of these three groups of infants were similar with respect to age, weight, height, nutritional patterns, and prior pregnancy histories.

Infant Birth

Infant birth weight is reported to decrease at high altitude as a reulst of fetal growth retardation (McCullough, Reeves, and Liljegren. Arch. Environ, Health. 32: 36--39, 1977) but not all babies born at high altitude are small. We hypothesized that maternal characteristics acting to lower arterial O2 content would contribute to smaller infant birth weight. To test this hypothesis, we measured arterial oxygenation serially during pregnancy and again postpartum in 44 residents of Leadville, CO (elevation 3,100 m). We identified three maternal characteristics--ventilation, hemoglobin concentration, and smoking habits--that were related to the birth weight of the offspring. Mothers of smaller babies (less than 2,900 g) compared to mothers of larger babies (greater than 3,500 g) were characterized by hypoventilation, no change or a decrease in ventilation and arterial O2 saturation from early to late gestation, and a falling hemoglobin concentration that combined to lower arterial O2 content in the 3rd trimester. Maternal smoking at 3,100 m was associated with a two to threefold greater reduction in infant birth weight (-546 g) than reported from sea level. Thus, maternal arterial oxygenation during pregnancy may be important for predicting fetal growth retardation and the process of adaptation to high altitude.

Microglial Development

Microglial activation is a key modulator of brain vulnerability in response to intra-uterine growth restriction (IUGR). However, the consequences of IUGR on microglial development and the microglial proteome are still unknown. We used a model of IUGR induced by a gestational low-protein diet (LPD) in rats. Microglia, isolated from control and growth-restricted animals at P1 and P4, showed significant changes in the proteome between the two groups. The expression of protein sets associated with fetal growth, inflammation, and the immune response were significantly enriched in LPD microglia at P1 and P4. Interestingly, upregulation of protein sets associated with the oxidative stress response and reactive oxygen species production was observed at P4 but not P1. During development, inflammation-associated proteins were upregulated between P1 and P4 in both control and LPD microglia. By contrast, proteins associated with DNA repair and senescence pathways were upregulated in only LPD microglia. Similarly, protein sets involved in protein retrograde transport were significantly downregulated in only LPD microglia. Overall, these data demonstrate significant and multiple effects of LPD-induced IUGR on the developmental program of microglial cells, leading to an abnormal proteome within the first postnatal days.

Hypertensive Rat

Epidemiological studies have linked low birth weight and increased placental weight with increased risk of hypertension in adult life. It has been proposed that the cardiovascular changes which lead to hypertension are initiated in utero by processes associated with intrauterine growth retardation. The alternative possibility, that hypertension may result from genetic influences which also determine fetal and placental size, has had less support because birth weight is not determined genetically in humans. However, in the spontaneously hypertensive rat (SHR) essential hypertension is known to be transmitted genetically. Fetal and placental weights were, therefore, measured at Day 20 gestation in SHRs and compared with those in the normotensive Wistar Kyoto (WKY) control strain. Fetal weight (1.93 +/- 0.04 g) was significantly (P < 0.001) reduced in SHRs compared with WKY fetuses (2.23 +/- 0.01 g) but placental weight was heavier (P < 0.001) in SHRs (0.347 +/- 0.005 g) than in WKY rats (0.300 +/- 0.006 g) although litter size was not different. As expected, maternal blood pressure recorded under 1% halothane anaesthesia was higher (126 +/- 2.7 mm Hg) in SHR than WKY rats (100 +/- 2.1 mm Hg; 1 mm Hg = 133 Pa). In addition the concentration of maternal blood glucose in SHR was significantly (P < 0.001) higher (4.8 +/- 0.32 mM v. 3.7 +/- 0.11 mM) and the concentration of plasma insulin was significantly (P < 0.05) lower in SHRs (18.8 +/- 3.0 ng mL-1) than in WKY dams (29.4 +/- 3.1 ng mL-1). Thus, the data support human population studies which show an association between adult hypertension and a reduced fetal:placental weight ratio at birth. However, because hypertension in the SHR is genetically determined, these data suggest that fetal growth retardation and increased placental weight may also be determined genetically.

Literary Sources

This study is an analysis of literary sources devoted to the use of transverse cerebellar diameter (TCD) and its relation to fetal abdominal circumference in the diagnosis of fetal growth restriction and determination of gestational age. All available research works on this subject were reviewed and a summary table with the results of the twenty-five most significant of them was compiled. The relevance of transferring TCD from the category of additional fetometry parameters to the category of standard fetometry parameters was indicated. Key words: fetal growth restriction, fetal growth retardation, transverse cerebellar diameter, gestational age, fetometry
