PURPOSE: to establish a normality curve of cervical length during pregnancy measured by transvaginal ultrasonography. METHODS: we conducted a prospective, longitudinal study on 82 healthy pregnant women who were followed up from the beginning of pregnancy to delivery at four-week intervals, of whom 49 concluded the study. Patients were divided according to parity into nulliparous women and women with one or more previous deliveries. Cervical length was measured in a sagittal view by transvaginal ultrasonography, as the linear distance between internal and external cervical os. RESULTS: no significant difference was observed in mean cervical length or the 5th, 25, 50th, 75th, or 95th percentile according to gestational age between groups (p>0.05). Between the 20thand 24th gestacional week, the 5th, 50th and 95th percentiles of cervical length were 28, 35 and 47.2 mm, respectively. Cervical length decreased progressively during normal pregnancy, with a significant shortening observed after 20 weeks of gestation and being more marked after 28 weeks (p<0.05). CONCLUSION: the pattern of cervical length behavior does not seem to differ between nulliparous women and women with one or more previous deliveries. The numerical values of the normality curve of cervical length according to gestational age reflect the variability in the peculiar characteristics of the studied sample, thus emphasizing the value of the parameters established for different populations.

Purpose: to investigate the interactions between maternal age and adverse perinatal outcomes in the State of Rio Grande do Norte. Methods: we analyzed official records of 57,088 infants in the State of Rio Grande do Norte, from January 1997 to December 1997. Data were obtained from the Information System of the Health Ministry, Brazil. The sample was divided into three Groups I, II and III according to maternal age range: 10 to 19 years, 20 to 34, and 35 or more, respectively. The main outcome variables were: length of pregnancy, birth weight and mode of delivery. Statistical analysis was performed using chi² test. Results: preterm deliveries were 4.3% in the adolescent group vs 3.7% in Group II (p = 0.0028). The incidence of cesarean section was higher in Group II than in the other Groups (p<0.001). Low birth weight was significantly higher in Groups I (8.4%) and III (8.3%) when compared with Group II (6.5%) (p<0.0001). Conclusions: we found a higher incidence of lower birth weight and preterm delivery in the adolescent group. In women ³35 years old there was a high incidence of low birth weight and macrosomia. Results suggest that cesarean sections are more common in women aged 20-34 years than in adolescent and older mothers.
