Good prenatal care is essential to guarantee maternal and perinatal health. Nowadays, with the constant progress on the diagnostic methods and changes in diseases panorama, like increased frequency of diabetes and sexually transmitted diseases, several diagnostic procedures have been studied. These challenges difficult the selection of prenatal exams by the clinicians, in order to improve maternal and perinatal outcome. This review aimed to evaluate the main prenatal routine exams, according to the best current scientific evidences.

OBJECTIVE: to determine the frequency of macrosomia in babies born alive at a reference obstetric service, and its association with maternal risk factors. METHODS: a transversal descriptive study, including 551 women at puerperium, hospitalized at Instituto de Saúde Elpídio de Almeida, in Campina Grande (PB), Brazil, from August to October, 2007. Women, whose deliveries had been assisted at the institution, with babies born alive from one single gestation and approached in the first postpartum day, were included in the study. The nutritional and sociodemographic maternal characteristics were analyzed, and the ratio of macrosomia (birth weight >4.000 g) and its association with maternal variables were determined. Macrosomia was classified as symmetric or asymmetric according to Rohrer's index. Statistical analysis has been done through Epi-Info 3.5 software; the prevalence ratio (PR) and the confidence interval at 95% (CI 95%) were calculated. The research protocol was approved by the local Ethics Committee and all the participants signed the informed consent. RESULTS: the mean maternal age was 24.7 years old, and the mean gestational age was 38.6 weeks. Excessive gestational weight gain was observed in 21.3% of the pregnant women, and 2.1% of the participants had a diagnosis of diabetes mellitus (gestational or clinic). A ratio of 5.4% of macrosomic newborns was found, 60 were asymmetric. There was no significant association between macrosomia, mother's age and parity. There was an association between macrosomia and overweight/obesity in the pre-gestational period (PR=2.9; CI 95%=1.0-7.8) and at the last medical appointment (PR=4.9; CI 95%=1.9-12.5), excessive weight gain (PR = 6.9; CI 95%:2.8-16.9), clinical or gestational diabetes (PR = 8.9; CI 95%:4.1-19.4) and hypertension (PR=2.9; CI 95%=1.1-7.9). The factors that persisted significantly associated with macrosomia in the multivariate analysis were the excessive weight gain during the gestation (RR=6.9; CI 95%=2.9-16.9) and the presence of diabetes mellitus (RR=8.9, CI 95%=4.1-19.4). CONCLUSIONS: considering that excessive gestational weight gain and diabetes mellitus were the factors more strongly associated with macrosomia, it is important that precocious detection measurements and adequate follow-up of such conditions be taken, aiming at preventing unfavorable perinatal outcomes.

A good quality prenatal assistance is essential to warrant perinatal and maternal health. Nowadays, due to the evolution of diagnostic methods and the change in illness prevalence, such as the increase in diabetes and sexually transmitted diseases, several propedeutic procedures are available. This introduces further difficulty for clinicians to select the most adequate procedures and when to apply them during gestation, assuring the best results for both mother and infant. The present review aimed at evaluating the main prenatal routine tests on the basis of the best scientific evidence presently available.

PURPOSE: to identify factors associated with gestation in adolescence in a State of the northeast of Brazil. METHODS: a case-control study in the ratio of one 10 to 19-year-old adolescent (case) for two 20 to 35-year-old women (controls), with a total of 168 cases and 337 controls. The variables analyzed were: schooling, marital status, origin, family income per capita in Brazilian currency, paid job, mother's schooling, and presence of adolescent's father at home. Reproductive variables such as age at the first intercourse, mother's history of adolescence pregnancy, gynecological appointments before the pregnancy, knowledge, access and use of contraceptive methods were also included in the analysis. RESULTS: the following variables were associated with gestation in adolescence: schooling lower than eight years, lack of a regular mate, and maternal history of adolescence gestation. Also, the age at the first intercourse was significantly lower among the adolescents and that they had a lower rate of gynecological appointments. Knowledge of hormonal methods and access to contraceptive methods were also less frequent among the adolescents. After the multiple logistic regression analysis, risk factors for pregnancy at adolescence were: low schooling (OR=2.3; CI95%=1.3-3.8), age at the first intercourse lower than 15 years old (OR=3.6; CI95%=2.2-5.7), history of maternal pregnancy at adolescence (OR=2.6; CI95%=1.7-3.4). The history of previous gynecological appointments (OR=0.3; CI95%=0.2-0.4) and the use of hormonal methods (OR=0.6; CI95%=0.4-0.9) were protecting variables. CONCLUSIONS: the main factors associated with pregnancy in adolescence were: the adolescent's low schooling, maternal history of adolescence gestation, lack of previous gynecological appointments and lack of access to contraceptive methods.

PURPOSE: to evaluate the effect of maternal, socioeconomic and obstetric variables, as well the presence of artery incisions in the 20th and 24th weeks on the fetal weight estimated at the end of pregnancy (36th week) in pregnant women attended by Programa Saúde da Família, in an inland town of the northeast of Brazil. METHODS: a longitudinal study including 137 pregnant women, who have been followed up every four weeks in order to assess clinical, socioeconomic and obstetric conditions, including their weight. The uterine arteries were evaluated by Doppler in the 20th and 24th weeks, the fetal weight and the amniotic fluid index (AFI), determined in the 36th week. The initial maternal nutritional state has been determined by the body mass index (BMI), the pregnant women being classified as low weight, eutrophic, over weight and obese. Weight gain during gestation has been evaluated, according to the initial nutritional state, being classified at the end of the second and third trimester as insufficient, adequate and excessive weight gain. Analysis of variance was performed to evaluate the association of the fetal weight in the 36th week with the predictor variables, adjusted by multiple linear regression. RESULTS: an association between the fetal weight estimated in the 36th week and the mother's age (p=0.02), mother's job (p=0.02), initial nutritional state (p=0.04), weight gain in the second trimester (p=0.01), presence of incisions in the uterine arteries (p=0.02), and AFI (p=0.007) has been observed. The main factors associated to the fetal weight estimated in the 36th week, after the multiple regression analysis were: BMI at the pregnancy onset, weight gain in the second trimester, AFI and tabagism. CONCLUSIONS: in the present study, the fetal weight is positively associated with the initial maternal nutritional state, the weight gain in the second trimester and the volume of amniotic fluid, and negatively, to tabagism.
