PURPOSE: To evaluate the methodological and statistical design evolution of the publications in the Brazilian Journal of Gynecology and Obstetrics (RBGO) from resolution 196/96. METHODS: A review of 133 articles published in 1999 (65) and 2009 (68) was performed by two independent reviewers with training in clinical epidemiology and methodology of scientific research. We included all original clinical articles, case and series reports and excluded editorials, letters to the editor, systematic reviews, experimental studies, opinion articles, besides abstracts of theses and dissertations. Characteristics related to the methodological quality of the studies were analyzed in each article using a checklist that evaluated two criteria: methodological aspects and statistical procedures. We used descriptive statistics and the χ2 test for comparison of the two years. RESULTS: There was a difference between 1999 and 2009 regarding the study and statistical design, with more accuracy in the procedures and the use of more robust tests between 1999 and 2009. CONCLUSIONS: In RBGO, we observed an evolution in the methods of published articles and a more in-depth use of the statistical analyses, with more sophisticated tests such as regression and multilevel analyses, which are essential techniques for the knowledge and planning of health interventions, leading to fewer interpretation errors.

PURPOSE: It was to evaluate the frequency and the risk factors of falls in early postmenopausal women. METHODS: A cross-sectional study was conducted on 358 women (age: 45-65 years and amenorrhea >12 months) with time since menopause <10 years. Exclusion criteria were: neurological or musculoskeletal disorders, vestibulopathies, uncorrected visual deficit, uncontrolled hypertension and postural hypotension, or drug use (sedative and hypnotic agents). A fall was identified as an unexpected unintentional change in position which causes an individual to remain in a lower level in relation to the initial position. The history of self-reported falls during the previous 24 months, and clinical and anthropometric data (body mass index (BMI) and waist circumference (WC)) and bone densitometric measures were analyzed. For statistical analysis, c² trend test and the logistic regression method (odds ratio (OR)) were used for the comparison between groups of women with and without falls. RESULTS: Of the 358 women, 48.0% (172/358) had a history of falls and 17.4% (30/172) had fractures. The fall occurred indoors (at home) in 58.7% (101/172). The mean age was 53.7±6.5 years, time since menopause 5.8±3.5 years, BMI 28.3±4.6 kg/m² and WC 89.0±11.4 cm. There were differences as the occurrence of smoking and diabetes, with greater frequency among fallers vs. non-fallers, 25.6 versus 16.1% and 12.8 versus 5.9%, respectively (p<0.05). By evaluating the risk of falls in the presence of influential variables, it was observed that risk increased with current smoking status (OR 1.93; 95%CI 1.01-3.71), whereas other clinical and anthropometric variables did not influence this risk. CONCLUSIONS: In early postmenopausal women there was higher frequency of falls. Current smoking was clinical indicators of risk for falls. With the recognition of factors for falling, preventive measures become important, as the orientation of abolishing smoking.

PURPOSE: To evaluate the quality of life of women with polycystic ovary syndrome (POS) and to learn about the experience of these women regarding the symptoms of their disease. METHODS: The study complementarily employed two methodological approaches - quantitative and qualitative ones. The quality of life of 213 women was evaluated (quantitative approach) using the SF-36 questionnaire. Of these, 109 had POS (Case Group: 26.8±5.4 years of age) and 104 were healthy (Control Group: 23.9±6.7 years of age). Data were analyzed statistically by the Student t-test, the chi-square test and the Pearson correlation test, with the level of significance set at 5%. Fifteen women with POS participated in the quantitative study and were interviewed using a semi-structured questionnaire. The qualitative data were analyzed by the technique of categorical thematic analysis. RESULTS: The women with POS showed impaired quality of life compared to Control (functional capacity: 76.5±20.5 and 84.6±15.9, respectively; physical aspects 56.4±43.3 and 72.6±33.3; general health status: 55.2±21.0 and 62.5±17.2; vitality: 49.6±21.3 and 55.3±21.3; social aspects: 55.3±32.4 and 66.2±26.7; emotional aspects: 34.2±39.7 and 52.9±38.2; mental health: 50.6±22.8 and 59.2±20.2). Regarding the qualitative data, thematic categorical analysis revealed that feelings of "abnormality", sadness, fear and anxiety were associated with the main symptoms of POS, i.e., hirsutism, menstrual irregularity, infertility and obesity. These symptoms affected the social, professional and marital life of these women. CONCLUSION: POS compromises the quality of life of affected women, causing them to feel that they are different from other women. Thus, women with POS do not simply require medical treatment regarding the reproductive, aesthetic and metabolic effects of the disease, but also need multiprofessional care.

PURPOSE: To evaluate the incidence of maternal and fetal repercussions and glycemic control in women with Gestational Diabetes Mellitus (GDM) using a fasting glucose of 85 mg/dL in the first trimester as a cut-off point and to correlate it with risk factors. METHODS: The medical records of pregnant women followed in the outpatient antenatal high-risk service (PNAR) of HRAN from January 2011 to March 2012 were reviewed and those women diagnosed with GDM were selected for contact and for prenatal card verification. We collected data of age, parity, fasting glucose during the first quarter, the value of the Oral Glucose Tolerance Test (OGTT), Body Mass Index (BMI), mode of delivery, form of control, effects and fetal risk factors for GDM. Statistical analysis was performed using the PSPP 0.6.2 software and consisted of descriptive analysis of frequencies, χ2 test for categorical variables, Student's t-test for independent samples, and Pearson test for correlations, with the level of significance set at 5%. RESULTS: From 408 pregnant women enrolled, 105 were diagnosed with GDM and 71 had complete records or answered to the contact in order to provide the missing information. The GDM-fasting <85 (fasting glucose <85 mg/dL at the first prenatal visit, in the first trimester) group consisted of 29 (40.8%) women and the GDM-fasting >85 (fasting glucose >85 mg/dL at the first prenatal visit, in the first trimester) consisted of 42 (59.1%) women. It was observed that few patients (five in the GDM-fasting <85 group and three in the GDM-fasting >85 group) had no risk factors for GDM. There was a major need for control with insulin in patients of the GDM-fasting >85 group. There was no significant difference related to fetal impact or mode of delivery between the groups. CONCLUSIONS: The first trimester fasting glycemia, with a cut-off value of 85 mg/dL alone or associated with risk factors, does not seem to be a good single predictor of the maternal-fetal effects of GDM.

PURPOSE: To analyze the impact of vaginal delivery after a previous cesarean section on perinatal outcomes. METHODS: Case-control study with selection of incident cases and consecutive controls. Maternal and perinatal variables were analyzed. We compared secundiparas who had a vaginal delivery after a previous cesarean delivery (VBAC) (n=375) with secundiparas who had a second cesarean section (CS) (n=375). Inclusion criteria were: secundiparas who underwent a cesarean section in the previous pregnancy; singleton and term pregnancy; fetus in vertex presentation, with no congenital malformation; absence of placenta previa or any kind of bleeding in the third quarter of pregnancy. RESULTS: The rate of vaginal delivery was 45.6%, and 20 (5.3%) women had forceps deliveries. We found a significant association between VBAC and mothers younger than 19 years (p<0.01), Caucasian ethnicity (p<0.05), mean number of prenatal care visits (p<0.001), time of premature rupture of membranes (p<0.01), labor duration shorter than 12 hours (p<0.04), Apgar score lower than seven at 5th minute (p<0.05), fetal birth trauma (p<0.01), and anoxia (p<0.006). In the group of newborns delivered by cesarean section, we found a higher frequency of transient tachypnea (p<0.014), respiratory disorders (p<0.048), and longer time of stay in the neonatal intensive care unit (p<0.016). There was only one case of uterine rupture in the VBAC group. The rate of neonatal mortality was similar in both groups. CONCLUSIONS: Vaginal delivery in secundiparas who had previous cesarean sections was associated with a significant increase in neonatal morbidity. Further studies are needed to develop strategies aimed at improving perinatal results and professional guidelines, so that health care professionals will be able to provide their patients with better counseling regarding the choice of the most appropriate route of delivery.

PURPOSE: To evaluate the adequacy of gestational weight gain and to determine its association with maternal socioeconomic, demographic and nutritional factors and health care, to estimate the prevalence of low birth weight, macrosomia, preterm birth and cesarean delivery and to identify the association of these outcomes with the adequacy of weight gain. METHODS: A cross-sectional study was performed in 2009/2010 to obtain socioeconomic, demographic, nutritional, dietary and physical activity data of pregnant women assisted by primary health care in a municipality of the state of São Paulo. Subsequently, data were collected from the medical records to evaluate gestational weight gain. Type of delivery, birth weight and gestational age at delivery were obtained from the Livebirths Information System. Gestational weight gain was evaluated according to the recommendations of the Institute of Medicine (2009). Associations were investigated by comparing the frequencies and by logistic regression, with excessive weight gain (yes, no) and insufficient gain (yes, no) being the dependent variables. RESULTS: A total of 212 pregnant women were studied: 50.5% had excessive gain and 19.8% insufficient weight gain. Only prepregnancy nutritional status was associated with adequacy of weight gain: compared with normal weight, prepregnancy overweight women had a four-fold higher chance to gain excessive weight (OR 4.66, 95%CI 2.19-9.4). Nearly a third of babies were born by caesarian section, 5.7% were premature, 7.1% were underweight and 4.7% were macrosomic. There was no association between adequacy of gestational weight gain and these outcomes. CONCLUSION: The proportion of inadequate gestational weight gain was high. Overweight pregnant women have a four-fold higher chance to gain excessive weight, and priority should be given to actions promoting adequate prenatal weight gain.

To investigate the association of perinatal variables with the birth of very low birth weight (VLBW) preterm newborns.
It was a retrospective study of the medical records of infants born after spontaneous preterm labor with admission to a neonatal intensive care unit. Preterm infants were divided into two groups: very low birth weight (VLBW) group (weight <1,500 g) and low birth weight (LBW) group (weight ≥1,500 g and <2,500 g). Prenatal variables such as maternal complications during pregnancy and childbirth/postpartum, and fetal/neonatal complications were investigated. Statistical analysis was performed using the Fisher exact test or χ2 test, with calculation of relative risk (RR), and the Student t test for comparison of group means, with the level of significance set at p≤0.05.
Hemorrhagic comorbidities (p=0.006; RR=1.2) and hypertension (p=0.04; RR=1.5), surgical delivery (p=0.001; RR=0.5), gestational age <33 weeks (p< 0.001; RR=16.7) and Apgar score at 1st and 5th minute (p=0.006; RR=1.6; p=0.01; RR=1.9) were associated with the occurrence of VLBW. Infants with VLBW had a significant association with the occurrence of metabolic comorbidities (p=0.01; RR=1.8), neurological (p=0.01; RR=1.7) and infectious diseases (p=0.001; RR=1.9), hospitalization >4 weeks (p=0.02; RR=1.8) and early neonatal death (p=0.0001; RR=2.9).
Factors such as hypertension and bleeding comorbidities during delivery and management of gestational age of less than 33 weeks were associated with the birth of VLBW newborns. This group of infants also showed higher RR for the occurrence of early neonatal death.

To analyze the serological, anatomopathological and parasitological results obtained from abortive material in order to detect infections with the risk of vertical transmission, with emphasis on toxoplasmosis.
A cross-sectional cohort study was conducted in order to determine the prevalence of infectoparasitic diseases. A total of 105 women who suffered spontaneous complete or incomplete abortion participated in the study. The women were interviewed, answered a questionnaire and had their blood and abortive material collected. Immunological tests were carried out in order to detect toxoplasmosis, Chagas disease, rubeola, cytomegalovirus and syphilis, and anatomopathological analysis of the ovular remains was performed.
55% of the women studied were 20 to 30 years old. Most of them (68%) presented a gestational age between the 7th and 14th week. 54.3% of the women had complete or incomplete high school education. Serological analysis showed cytomegalovirus (CMV) as the most common vertically transmitted infection with 97.1% positivity, followed by rubeola with 95.2%. Toxoplasmosis showed 54.3% positivity, Chagas disease 1.9% and syphilis 0.95%. Anatomopathological analysis showed inflammation in 63.1% of the cases and absence of inflammation in 34%. The results of the serological, anatomopathological and parasitological analysis of the 105 participants showed that 57 women were T. gondii positive. However, none showed positivity in the polymerase chain reaction (PCR) or in mouse inoculation.
The prevalence of diseases with the risk of vertical transmission is important in women with spontaneous abortion, indicating the need for more research in order to investigate the etiology of abortion.

The results of the serological, anatomopathological and parasitological analysis of the 105 participants showed that 57 women were T. gondii positive. However, none showed positivity in the polymerase chain reaction (PCR) or in mouse inoculation.
The prevalence of diseases with the risk of vertical transmission is important in women with spontaneous abortion, indicating the need for more research in order to investigate the etiology of abortion.
