PURPOSE: to study the histological modifications that occur in the endometrium of women before and six months after tubal ligation (TL) and to correlate these findings with progesterone (P4) levels. METHODS: the study was conducted on 16 women with normal menstrual cycles who were evaluated before and in the sixth cycle after TL. P4 levels were determined from the 8th day at 2-day intervals until ovulation and on the 8th, 10th and 12th day after ovulation or on the 24th day of the cycle. An endometrial biopsy was obtained between the 10th and 12th day after ovulation or on the 24th day of the cycle and a correlation with P4 was determined. Data were analyzed statistically by the nonparametric McNemar test for the evaluation of hormonal determination and by the exact Fisher test for the histological evaluation of the endometrium, with the level of significance set at p<0.05. RESULTS: mean age was 34.1±1.3 years. The intermenstrual interval was 27.1±2.6 days and the duration of bleeding was 3 to 5 days, with no difference between the studied periods. Before TL, 8/16 (50.0%) of the cases had a secretory endometrium according to the cycle, 3/16 (18.8%) had a secretory endometrium not according to the cycle and 3/16 (18.8%) had a dysfunctional endometrium, suggesting a defect in the luteal phase in 6/16 (37.5%). After TL, 7/16 (43.8%) had a secretory endometrium according to the cycle, 3/16 (18.8%) a secretory endometrium not according to the cycle and 4/16 (25.0%) had a dysfunctional endometrium, suggesting a defect in the luteal phase in 7/16 (43.8%). In 2/16 (12.5%) of the cases before TL and in 2/16 (12.5%) other cases after TL it was not possible to perform histological evaluation due to insufficient material or unspecfiic endometritis. In the luteal phase after TL, mean P4 levels were significantly lower on days +8, +10 and +12 than before TL, being 15.1, 18.0 and 20.7 ng/ml, respectively, before TL and 10.6, 8.0 and 5.4 ng/ml after TL (p<0.05). Before TL, 5/8 (62.5%) of the cases with a secretory endometrium according to the cycle had P4 >10 ng/ml and 3/8 (37.5%) had P4 <10 ng/ml. After TL, when the endometrium was secretory according to the cycle, P4 was >10 ng/ml in 4/7 (57.1%) and <10 ng/ml in 3/7 (42.9%). These differences were nonsignificant (p>0.05). CONCLUSION: six months after TL, the intermenstrual interval and the duration of bleeding were unchanged. P4 levels decreased during the luteal phase although this did not interfere in the endometrial response.

PURPOSE: to check whether there were differences in some social indicators between adolescent and adult pregnant women in the city of Ribeirão Preto, from January 1992 to December 1996. METHODS: the information was obtained from hospital discharge forms and was analyzed at the Hospital Data Processing Center of the FMRP-USP. The analyzed parameters were: number and types of deliveries, category of hospital admission, occupation, and obstetric diagnosis. The 6.04a text processor Epi-Info System, a data bank and statistics of epidemiology produced by the Centers of Disease Control and Prevention (Atlanta, GA, USA), and Dbase IV were used to process the information. The association between variables was tested by the chi² test, with level of significance set at 5%, using the GraphPad Prism version 2.0, 1995 software. RESULTS: a total of 43,253 deliveries occurred during this period, among which 7,134 (16.5%) corresponded to adolescent deliveries, while 36,119 (83.5%) to adult deliveries. The number of deliveries by adolescent girls increased 25.5% along this period. The proportion of adolescent deliveries in the unified health system category of admission increased, and it was higher than that of the adults'. Only 14.1% of the adolescents belonged to the economically active population, comparing with 34.8% of the adults. Only 6.8% of the adolescents were students, while 79.0% were house-workers or had a nonpaid occupation. In the analyzed period, the ratio of vaginal delivery increased among the adolescents, as compared to that of the adults. The ratio of cesarean delivery persisted stable and higher among the adults. Premature delivery and false labor were significantly more frequent among the adolescents. CONCLUSION: the number of deliveries increased among the adolescents, and most of them were normal. The ratio of admission by the unified health system category and that of vaginal delivery were higher among the adolescents. There were more adolescents without an economically active work. Thus, we recommend strategies to prevent adolescent pregnancy, mainly among the poor population.

Purpose: the objective of the present study was to determine the number and type of deliveries, category of admission to the hospital, occupation and obstetrical diagnosis for adolescents from the municipality of Ribeirão Preto, from January 1992 to December 1996. Methods: the information obtained from hospital discharge forms was analyzed at the Hospital Data Processing Center. The 6.04a-text processor Epi-Info System, a data bank and statistics for epidemiology produced by the Centers of Disease Control and Prevention (Atlanta, GA, USA), and Dbase IV were used to process the information. The association between variables was tested by the chi² test, with the level of significance set at 5%. The analyzed parameters were: number and type of delivery, category of hospital admission, occupation and obstetric diagnosis. Results: a total of 42,969 deliveries occurred during the study period, among which 7,134 (16.6%) corresponded to adolescent deliveries. An increase in the number of deliveries by girls in this age range occurred over the years, from 1,225 in 1992 to 1,538 in 1996. Deliveries were reported starting from 12 years of age, with a gradual increase in this number, especially after 14 years of age, when a 104.2% increase occurred for deliveries at this age, followed by 48.8% at 15 years, 36.1% at 16 years, 14.0% at 17 years, 52.8% at 18 years, and with practically no increase among 19-year-old girls. The highest number of deliveries (5,709) was recorded for the unified health system category of admission, followed by 1,277 deliveries for the prepaid category and 148 deliveries for the private category. With respect to occupation, 14.1% of the patients belonged to the economically active population, while 85.8% did not. Of the total deliveries, 59.2% were normal, 5.6% were forceps deliveries, and 35.2% were cesarean sections. The most frequent obstetrical diagnoses were: problems of fetus or placenta affecting maternal management (7.9%), fetus-pelvis disproportion (6.0%), problems with the amniotic cavity and membranes (5.0%), hypertension complicating delivery and puerperium (3.5%), and premature or false labor (3.4%). Conclusions: most deliveries were normal and occurred more frequently at the end of adolescence, especially among girls belonging to the unified health system. There was a predominance of adolescents not belonging to the economically active population. Some obstetrical complications were diagnosed at the time of resolution of pregnancy.
