Despite the advances in therapy, the high incidence, high mortality, and prematurity of coronary heart disease demonstrate the need for prevention. Measurement of a series of easily determined risk factors permits the early recognition of subjects at risk with remarkable reliability. However, reduction of risk factors affords protection against the illness only if they are causally connected with the disease mechanisms. The major evidence for linking atherosclerosis and its consequences with risk factors is reviewed. Particular attention is focused on serum lipids and the "lipid theory", smoking, elevated blood pressure, and physical inactivity, which are, on the basis of current knowledge, not only the most important factors but those most readily influenced by changes in daily living habits. Among the multiple risk factors mention is also made of obesity, diabetes, psychosocial stress, and hereditary predisposition. The probability of a causal relationship between risk factors and disease mechanisms justifies every effort to prevent the development of these precursors, or to treat them prophylactically if already present.

In 50 children with obesitas simplex, 6-14 years of age, the triglycerides (TG), free fatty acids (FFA) and cortisol (F) levels in venous blood serum were estimated. In agreement with the development stages, studied patients were divided into the group of younger children in prematurity stage and the group of older children approaching the maturity. Obtained mean values of TG, FFA and F concentrations were analysed in the particular groups of obese children and compared with the healthy children of the same age. Mean concentrations of TG, FFA and cortisol in obese children were within the normal values and statistically did not differ from those of control healthy children. Also there was no difference in parameters studied if compared the younger and older groups of obese children. There was no interrelationship between the high birth weight and the degree of overweight as well as between the duration of obesity and the blood serum TG levels. In the course of obesitas simplex in children no detectable disturbances in the levels of TG, FFA and cortisol were found. It may depends on the more efficient adaptational mechanism connected with metabolism which are acting in the course of overfeed in the period of growth and development.

To describe maternal body mass index and to compare the use of maternal weight and body mass index for risk assessment at the initial prenatal visit, 6270 gravid women who were consecutively delivered of infants were studied. Body mass index increased with advancing maternal age, parity, and advancing gestational age and was significantly greater in black women than in nonblack women. Risks for the development of adverse outcome associated with maternal obesity, including development of gestational diabetes, preeclampsia, fetal macrosomia, and shoulder dystocia, were comparably predicted by either maternal weight or body mass index greater than 90th percentile. Maternal weight was as predictive of preeclampsia, macrosomia, and shoulder dystocia as was body mass index when these factors were analyzed as continuous variables, whereas increasing body mass index was more predictive of gestational diabetes. The prediction of factors associated with low maternal weights, small-for-gestational-age birth, prematurity, low birth weight, and perinatal death was equivalent for maternal weight and body mass index that was less than 10th percentile. This study indicates that in the initial risk assessment of outcomes related to maternal weight, the calculation of maternal body mass index offers no advantage over simply weighing the patient. This finding contrasts with results in nonpregnant women.

The obstetric outcome of 1328 deliveries in a tertiary level hospital was examined, focusing on the results of the women over 35. The study group were all pregnant women over 20 primarily cared for and delivered at the New York Hospital-Cornell Medical Center from September 1984- February 1985, excluding those transferred from other institutions for complications. Among the older women, there was a higher incidence of previous abdominal operations, cesarean sections, previous perinatal death, infertility and alcohol abuse, but relatively few had comorbid conditions or obesity. Most were of higher socioeconomic status and had private physicians. The older group tended to begin prenatal care early, and elect to have amniocentesis. They had a higher risk of gestational glucose intolerance, hypertension and hospitalization during this pregnancy. 45% had cesarean delivery, and their hospital stays were longer. Their rates of vertex presentation, prematurity, postmaturity, macrosomia, induced or augmented labor were similar to those of younger women. There were no maternal deaths. The older group had 1 multiple birth, fewer than the younger women. Perinatal mortality was lowest in the older women. There was 1 intrauterine death and 1 congenital anomaly, lower rates than seen in younger women. This series demonstrates that women over 35 are not at greater risk of adverse pregnancy outcomes if they are cared for early and carefully.

Screening of 717 5-year-olds and 757 7-year-olds, found 55 of the former and 77 of the latter possibly to be poorly coordinated. Further diagnostic testing with the McCarthy Motor Scales confirmed the problem in a total of 95 children, a prevalence of 6.4%. Neurological examination showed 43% of the 5-year-olds and 21% of the 7-year-olds to have choreiform movements. Of the total 95, proprioception was abnormal in 40%, but abnormal muscle tone present in only 4%. An increased prevalence of hearing loss and obesity and a history of developmental delays was found. Low birth weights, prematurity, post-maturity and perinatal problems were significantly associated with poor coordination. Socioeconomic status was not a significant factor. The difficulties of testing and measuring poor coordination and the need for more precise measures are discussed. Follow-up of at risk children at age 5 with tests of motor coordination is recommended.

Maternal obesity has been associated with both gestational diabetes mellitus (GDM) and neonatal macrosomia. Most studies of obesity in pregnancy have demonstrated an increased risk for GDM. However, the contribution of obesity as an added risk in GDM has not been examined. The purpose of this study was to examine the contribution of obesity as a risk factor to perinatal morbidity in gestationally diabetic women by comparing the maternal and neonatal outcome in obese and nonobese gestationally diabetic women. From 1979 to 1983, the maternal, intrapartum, and neonatal characteristics of all prepartum gravid patients with GDM were examined. Of the 158 patients with documented GDM, 62 (39%) were obese (weight greater than 90 kg). There was no difference in maternal age (obese 29.3 +/- 5.4 years, nonobese 28.7 +/- 6.5 years) parity, or prepartum risk score between the obese and nonobese patients. The incidence of prematurity, pre-eclampsia, fetal distress, and primary cesarean sections were not different between the groups. There were no differences in Apgar scores, gestational age, or perinatal morbidity. However, the obese patients delivered heavier neonates expressed as mean birthweight (obese 3667 +/- 682 gms, nonobese 3331 +/- 750 gms. P less than .01), the number of macrosomic (greater than 4 kg) neonates (obese 37%, nonobese 14%, P less than .001) and K-score, (obese 0.8 +/- 1, nonobese 0.4 +/- 9, P less than .05). These data indicate that obese patients with GDM have an increased risk of neonatal macrosomia.(ABSTRACT TRUNCATED AT 250 WORDS)

This study assesses the widely held but previously untested hypothesis that the net weight of postpartum candy gifts from parents to delivery suite and postnatal ward staff is proportional to their neonates' birth weight. Midwives at Musgrove Park Hospital in Taunton, Somerset, United Kingdom were requested to record the details of all candy gifts received over a 6-month period in 1992. Only 39 candy gifts from 1491 deliveries were documented, with a mean net weight of 416 g. The coefficient of correlation between candy weight and birth weight was 0.1477 (P = .2). The basis for the association is multifactorial. Socioeconomic and prematurity-related factors were responsible for poor candy giving following low birth weight deliveries. In contrast, factors related to the etiology and psychology of obesity and diabetes were implicated in generous candy giving by the high birth weight population.

The perinatal mortality rate of infants of diabetic mothers (IDMs) has declined dramatically from 250 per 1000 live births in the 1960s to a near-normal 20 per 1000 live births in the 1980s. Five to 8% of all IDMs suffer from major congenital malformations, and it is the latter that are responsible for 50% of these perinatal deaths. It has been shown that tight glycemic control prior to conception and during pregnancy can prevent an excess rate of congenital malformations, fetal macrosomia, birth trauma, and neonatal respiratory distress syndrome. We briefly review the short- and long-range complications that occur in offspring of diabetic mothers (ODMs) from gestation through young adulthood. Short-term neonatal complications, such as hypoglycemia, hypocalcemia, hypomagnesemia, hyperbilirubinemia, and polycythemia, are related mainly to fetal hyperinsulinemia, hypoxemia, and prematurity. They are readily controllable within the setup of modern neonatal intensive care units. Long-range complications include an increased rate of childhood and adolescent obesity, impaired glucose tolerance or diabetes mellitus, and subtle neuropsychological dysfunctions. These may be related to the severity of the maternal hyperglycemia during pregnancy, the consequent fetal hyperinsulinemia, and third trimester maternal lipid metabolism disturbances. Today we have at hand the knowledge and tools to properly treat both pregestational and gestational diabetes. Increased education of the general practitioner and the target population regarding early referral of pregestational diabetic mothers and the implementation of screening programs for gestational diabetes will further reduce diabetic pregnancy-related morbidity.

Prematurity, maternal smoking, and low birth weight each result in neuroendocrine dysfunction and increased perinatal morbidity and mortality. Leptin, an adipocyte-secreted protein, has provided the first physiological link to the regulatory system controlling starvation-induced neuroendocrine changes in rodents. This study investigated whether leptin concentrations were detectable in cord blood of newborns, and assessed the effect of birth weight, prematurity, and maternal smoking on cord blood leptin concentrations. Fifty consecutively enrolled full-term and 12 preterm newborns born to mothers who smoked during pregnancy were compared to 50 full-term and 12 preterm newborns born to parents who were nonsmokers. RIA for leptin was performed using cord blood samples collected immediately after birth. Leptin concentrations were detectable in newborns and correlated positively with obesity (full-term, r = 0.30, P < 0.01; preterm, r = 0.47, P < 0.05). Maternal smoking during pregnancy was associated with decreased leptin concentrations in the cord blood of both full-term and preterm newborns. This effect was independent of obesity (full-term newborns: 5.25 +/- 2.48 vs. 4.21 +/- 2.71 ng/ml, P = 0.01) and was more pronounced in premature newborns (5.67 +/- 3.6 vs. 2.46 +/- 2.03, P = 0.02), and its magnitude in full-term newborns was directly related to the reported number of cigarettes the mothers of the full-term newborns smoked per day (r = -0.438, P < 0.001). Thus, low birth weight and maternal smoking are both associated with decreased leptin concentrations, and these effects are more pronounced in premature newborns. Future studies will be needed to determine whether administration of leptin might reverse the neuroendocrine dysfunction caused by maternal smoking.

The presence of insulin-dependent or non insulin-dependent diabetes mellitus in pregnant women has been associated with an adverse effect on the maternal an fetal outcomes of pregnancy. The incidence of obstetrical and diabetic complications is increased, and a continuum has been observed between maternal blood glucose levels and perinatal outcome. The incidence of congenital malformations, macrosomia and prematurity is increased in offspring of diabetic mothers. Programming and intensive collaborative follow-up improve the outcome of such pregnancies. Gestational diabetes mellitus is an heterogenous condition defined as carbohydrate intolerance of variable severity with onset or first recognition during pregnancy. Short term complications are mainly represented by fetal macrosomia and high cesarean section rate. Women with a history of gestational diabetes mellitus are at increased risk of future diabetes, predominantly type 2. Obesity and type 2 diabetes are increased among their children.
