As shown in 870 white participants in the National Collaborative Perinatal Project (NCPP), maternal health status during pregnancy and birth size are systematically related to mesiodistal and buccolingual crown dimensions of I1, I2, dc, dm1, dm2 and M1. Maternal diabetes, maternal hypothyroidism and large size at birth are associated with larger maxillary and mandibular teeth in white children. Conversely, deciduous and permanent crown diameters are diminished in maternal hypertension, and in low birthweight and small birth-length conditions. These findings suggest that maternal and fetal (or gestational) determinants of both deciduous and permanent tooth crown dimensions may account for as much as half of crown-size variability with major implications to population comparisons and historical odontometric differences and trends.

To evaluate its specificity as an indicator of placental function or fetal status, maternal serum heat-stable alkaline phosphatase (HSAP) was measured serially in 76 normal and 161 high-risk pregnancies (1272 determinations). The previously reported curvilinear HSAP rise starting at about 28 gestational weeks was noted. No relation was seen between HSAP levels and milk or moderate hypertension, gestational diabetes, nontoxemic placental insufficiency, or maternal blood group. HSAP levels were mostly above normal in proteinuric hypertension and were low normal in pregnant insulin-dependent diabetics. Two neonatal deaths were associated with normal HSAP levels. Of 4 intrauterine deaths, 1 was associated with high, 1 with low, and 2 with rising values in the normal range. Serial maternal HSAP values are apparently not a specific indicator of placental function or fetal status.

The only drugs which commonly cause diabetes during therapeutic use are the anti-hypertensive vasodilator diazoxide, and corticosteroids in high doses such as those used to palliate intracranial tumours. Thiazide diuretics have in the past been used in higher doses than necessary to treat hypertension, and the lower doses now used probably carry only a slight risk of inducing diabetes. The risk from beta-blockers is also quite small, but there is some evidence that thiazides combined with beta-blockers may be more likely to cause diabetes than either drug alone. The combination is probably best avoided in patients with a family history of non-insulin-dependent diabetes. The effect of the low-oestrogen combined oral contraceptive pill seems to be slight, and it presents a risk only to women who have had gestational diabetes. Bodybuilders who take enormous doses of anabolic-androgens can develop impaired glucose tolerance. Several drugs, including theophylline, aspirin, isoniazid and nalidixic acid can cause transient hyperglycaemia in overdosage, but only streptozotocin, alloxan and the rodenticide Vacor are likely to cause permanent diabetes.

The authors revealed during dispensarization of pregnant women suffering from essential hypertension that the disease is relatively frequently associated with some metabolic disorders, i. e. obesity, gestational diabetes or impaired glucose tolerance. They draw attention to a similarity with Reaven's syndrome in non-pregnant women. The authors recommend to screen for diabetes all obese pregnant women and those with hypertension to detect an impaired glucose metabolism and prevent foetopathies in neonates of thus affected mothers. The authors consider obesity one of the subsidiary criteria in the differential diagnosis of essential hypertension and preeclampsia.

Modern oral contraceptive pills are safe for the majority of American women. The most important contraindications to oral contraceptive pill use are a history of thrombophlebitis or thromboembolism while on the pill or during pregnancy, smoking over 15 cigarettes daily if over 35 years of age, active liver disease, hypertension, diabetes, a lipid disorder, or breast cancer. A history of gestational diabetes is not an absolute contraindication to oral contraceptive pill use, but women with such a history must be encouraged to exercise and eat properly to reduce the high risk of developing overt diabetes. Couples should be encouraged to use condoms to reduce the risk of sexually transmitted diseases. Most antibiotics do not decrease the effectiveness of the pill. Nonuse of contraception among adolescents and older couples is the most common reason for failure. Postcoital contraceptive pills are available but are not completely effective. The use of modern contraceptives is almost always safer than nonuse.

Physical training is associated with lower plasma insulin concentrations and increased sensitivity to insulin in skeletal muscle and adipose tissue of individuals with non-insulin-dependent diabetes mellitus (NIDDM). The benefits of exercise to individuals with NIDDM in terms of increased insulin sensitivity could be applied to reversing the insulin resistance associated with gestational diabetes mellitus (GDM). Exercise may also benefit women with GDM by acting as an adjunct to diet in preventing excessive weight gain and preventing or decreasing the severity of hypertension and/or hyperlipidemia during pregnancy. Regular physical exercise should be considered as a potential approach to the prevention and treatment of GDM.

Obstetric complications recorded prospectively were assessed retrospectively in 150 women with gestational diabetes mellitus (GDM) and 305 control subjects matched for age, parity, and ethnicity. Intensive diet therapy and self-monitoring of capillary blood glucose were used to obtain postprandial euglycemia; 22% of GDM subjects required insulin. GDM and control subjects were grouped by body mass index to detect any influence of maternal prepregnancy weight on outcome. Polyhydramnios, preterm labor, and pyelonephritis were not more frequent in GDM, but hypertension without proteinuria (7.3 vs. 3.3%) and preeclampsia (8 vs. 3.9%) were more frequent in GDM. The frequency of hypertensive complications in GDM was not totally attributable to being overweight. Abnormalities of labor, birth trauma, and fetal macrosomia were not more common in GDM; 6.7% of the infants of mothers with GDM weighed greater than 4200 g at birth compared with 3.6% of control infants (NS), and 10% were large for gestational age and sex compared with 6.6% of control infants (NS). Despite this, cesarean delivery was more common in GDM (35.3 vs. 22%, P less than 0.01), mostly due to significantly more cesarean births without labor.

Gestational diabetes mellitus (GDM) is associated with increased risk of poor outcomes for the pregnancy. It is a strong risk factor for subsequent diabetes. The epidemiology of GDM in African-American women is not well known. It has not been demonstrated that their risk factors are similar in character and weight to those among White women. There is considerable multicollinearity among GDM risk factors such as age, parity, obesity, hypertension, and family history of diabetes, and this needs to be sorted out. This review is based on the results of a nested case-control study to evaluate the frequency of, and the relationships of the known risk factors with, the onset of GDM among African-American women. All cases of GDM within a cohort of women seen at any of the county health department clinics in Jefferson County, Alabama from 1981 to 1987 were identified. The cohort represents approximately 63% of all African-American pregnancies in the county during the period. With few exceptions (5.1% based on fasting plasma glucose greater than or equal to 120 mg/dl), potential GDM cases (7.1%) were selected on the basis of a 2 h post 100 g carbohydrate meal screening plasma glucose measure at their second prenatal visit and again at 28-32 weeks greater than or equal to 115 mg/dl and diagnosed on the basis of the results of an oral glucose tolerance test (OGTT) using the criteria of O'Sullivan and Mahan. Women with any prior history of diabetes (even in pregnancy), 1.6%, were excluded. The frequency of the new diagnosis of GDM among African-American women in this pregnancy in the cohort was 2.5% of pregnancies and 3.4% of women, which is similar to the values reported in the other studies. Controls were selected from women with negative screening tests who delivered after a GDM subject. The results reported in this paper reflect 358 cases (86% of all eligible GDM cases identified) and 273 controls. Cases were significantly older (28.3 vs. 21.7 years), of higher gravidity (2.7 vs. 1.9), more obese (76.7 vs. 61.7 kg), gained weight more rapidly (0.34 vs. 0.28 kg/week), had more hypertension in this pregnancy (28.2 vs. 2.6%), and there was a higher proportion with a family history of diabetes (41.3 vs. 16.5%) (p less than 0.001 for all comparisons). Because there were significant correlations among the risk factors in both cases and controls, multivariable logistic regression analyses were performed.(ABSTRACT TRUNCATED AT 400 WORDS)

Delay in fetal maturation in diabetic and accelerated fetal maturation in hypertensive pregnancies have been reported in the past. The spontaneous activity of fetal nervous system during pregnancy was followed longitudinally in a group of 29 normal pregnancies from 28 x th to 40 x th week of gestation by means of fetal behavioural states determination. 1 F state (quiet sleep) progressively increases from median values of 5.0% to values of 22.5-25% at term of pregnancy. This state represents the positive activity of inhibitory centers has been related to a positive evolutionary process of brain maturation according to preceding experiences conducted on experimental models and preterm babies followed with EEG and direct observation in the early neonatal period. The method of behavioural states determination has been applied to a group of 33 gestational diabetes (GDM) pregnant women followed longitudinally, and a clear reduction of development of 1 F state has been evidentiated, with significant differences (p less than 0.001) at 35-36 weeks of gestation versus the control group. The normal values are reached in concomitance with L/S value of maturity. In 30 pregnant women affected by gestational hypertension (GH) different result are obtained: 1 F state seems to develop earlier, and is increased (p less than 0.001) around 30-32 weeks versus the control group if a fetal growth reduction is present. The value of 1 F behavioural state in the evaluation of fetal condition of pathological pregnancies is discussed.

Medical disorders, including hypertensive diseases, may exist prior to pregnancy (eg, connective tissue diseases, chronic hypertension, thyroid disease) or may manifest themselves for the first time during pregnancy (eg, gestational diabetes, gestational hypertension). The outcome for a particular pregnancy will depend on the nature of the disease, the severity of the disease process at onset of pregnancy, and the quality of obstetric and medical management used. Management of pregnancies with preexisting medical disorders should begin before conception. These women should be evaluated to determine the severity of the disorder and to establish the presence of possible target organ damage. In addition, they should be counseled regarding the potential adverse effects of the disease on pregnancy outcome and the effects of pregnancy on their disease. These women should be instructed regarding the importance of early onset of prenatal care and compliance with frequent prenatal visits.
