PURPOSE: To determine the prevalence and risk factors associated with failure of voluntary screening for cervical cancer during the gestational period in Rio Grande, Rio Grande do Sul State, Southern Brazil. METHODS: Previously trained interviewers applied a standardized questionnaire in the maternity to all mothers from this municipality who had delivered from January 1st to December 31st 2010 to obtain information about the demographic characteristics of the pregnant women, family socioeconomic status, and prenatal care received. The χ² test was used to compare proportions and Poisson regression with robust adjustment of variance was used in the multivariate analysis. RESULTS: Among the 2,288 respondents, 33% were not submitted to the Pap smear during pregnancy. Two thirds of these women stated that they were not aware of the need to perform it, 18% were not screened out of fear or shame, and the rest for other reasons. After adjustment, the highest prevalence ratios (PR) for noncompliance with the Pap smear occurred among young women (PR=1.5; 95%CI 1.25 - 1.80), with lower educational level (PR=1.5; 95%CI 1.12 - 2.12), who were living without a partner (PR=1.4; 95%CI 1.24 - 1.62), smokers (PR=1.2; 95%CI 1.07 - 1.39), who did not plan the current pregnancy (PR=1.3; 95%CI 1,21 - 1.61), who had attended less than six medical visits during the prenatal period (PR=1.4; 95%CI 1.32 - 1.69) and among users of oral contraceptives (PR=1.2; 95%CI 1.04 - 1.38). CONCLUSIONS: The higher the risk for uterine cervical cancer, the less likely a pregnant woman is to undergo a Pap smear. This definitely contributed to the increased morbidity and mortality from this disease in this setting.

PURPOSE: To determine the pattern of alcohol use before and during pregnancy and associated risk factors in puerperal women hospitalized in a public university hospital in Southeastern Brazil. METHODS: Between June and September 2009, 493 puerperae were consecutively evaluated. Those with cognitive impairment were excluded from the study. The AUDIT and CAGE questionnaires were used to diagnose alcohol use/abuse before pregnancy, in addition to the T-ACE during pregnancy. Another questionnaire was applied to collect sociodemographic data, such as age, educational level, marital status, and household income. The χ² test was used in the statistical analysis and the Odds Ratio (OR) and 95% confidence interval (95%CI) were calculated. A p-value <0.05 was considered to be significant. RESULTS: Before pregnancy, the CAGE was positive in 50/405 (12.3%) women and the AUDIT identified alcohol use in 331 (67.1%), which was of low risk in 233 (47.3%), risky in 73 (14.8%), and harmful or indicating possible alcohol dependence in 25 (5%). During pregnancy, the CAGE was positive in 53/405 (13.1%) women and the T-ACE in 84 (17%); the AUDIT identified alcohol use in 114 women, which was of low risk in 73 (14.8%), risky in 27 (5.5%), and harmful or indicating possible alcohol dependence in 14 (2.8%). During pregnancy, alcohol use was more frequent (OR=2.8; 95%CI 1.2 - 6.2) among women with a lower educational level (8.8 versus 3.3%) and more frequent (OR=3.8; 95%CI 1.3 - 11.1) among those who did not cohabit with a partner (6 versus 1.7%). Among pregnant women who drank alcohol, 49/114 (43%) were advised to stop drinking. CONCLUSIONS: Alarming alcohol use was observed during pregnancy, especially among pregnant women with a lower educational level and those who did not cohabit with a partner. There was a low frequency of counseling aimed at abstinence and the AUDIT was the instrument that most frequently diagnosed alcohol consumption.

PURPOSE: To assess the prevalence of obstetric risk factors and their association with unfavorable outcomes for the mother and fetus. METHODS: A longitudinal, descriptive and analytical study was conducted on 204 pregnant women between May 2007 and December 2008. Clinical and laboratory assessments followed routine protocols. Risk factors included socio-demographic aspects; family, personal and obstetric history; high pre-gestational body mass index (BMI); excessive gestational weight gain and anemia. Adverse outcomes included pre-eclampsia (4.5%), gestational diabetes mellitus (3.4%), premature birth (4.4%), caesarian birth (40.1%), high birth weight (9.8%) and low birth weight (13.8%). RESULTS: The average age was 26±6.4 years; the mothers were predominantly non-white (84.8%), 51.8% had incomplete or complete secondary level schooling, 67.2% were in a stable marital relationship and 51.0% had a regular paid job; 63.7% were admitted to the prenatal clinic during the second trimester and 16.7% during the first, with 42.6% being primiparous. A past history of chronic hypertension was reported by 2.9%, pre-eclampsia by 9.8%, excessive gestational weight gain by 15.2% and former gestational diabetes mellitus by 1.0%. In the current pregnancy, elevated pre-gestational BMI was found in 34.6%; 45.5% presented with excessive gestational weight gain, 25.3% with anemia and 47.3% with dyslipidemia. Of the 17.5% of cases with altered blood glucose, gestational diabetes mellitus was confirmed in 3.4% and proteinuria occurred in 16.4% of all cases. Adverse maternal fetal outcomes included pre-eclampsia (4.5%), gestational diabetes mellitus (3.4%), premature birth (4.4%), caesarean birth (40.1%) and high and low birth weight (9.8% and 13.8%, respectively). Independent predictors of adverse maternal fetal outcomes were identified by Poisson multivariate regression analysis: pre-gestational BMI>25 kg/m² was a predictor for pre-eclampsia (RR=17.17; 95%CI 2.14-137.46) and caesarian operation (RR=1.79; 95%CI 1.13-2.85), previous caesarean was a predictor for present caesarean operation (RR=2.28; 95%CI 1.32-3.92) and anemia and high gestational weight gain were predictors for high birth weight (RR=3.38; 95%CI 1.41-8.14 and RR=4.68; 95%CI 1.56-14.01, respectively). CONCLUSION: Pre-gestational overweight/obesity, previous caesarean, excessive weight gain and anemia were major risk factors for pre-eclampsia, caesarean operations and high birth weight.

PURPOSE: To determine the frequency and the association of serum markers for inherited and acquired thrombophilias in pregnant women with a history of severe pre-eclampsia in previous pregnancies. METHODS: Case-control study consisting of 81 pregnant women with a history of severe pre-eclampsia in previous pregnancies (study group) and 32 women with no history of severe pre-eclampsia in previous pregnancies (control group). The presence of inherited thrombophilia and antiphospholipid antibodies was screened in both groups. We used the chi-square test with Yates correction to assess associations and calculate the relative risks. RESULTS: The presence of thrombophilia was detected in 60.0% of patients with a previous history of pre-eclampsia and in 6.0% of the control patients. A significant association was found between pre-eclampsia in a previous pregnancy and the presence of markers for hereditary thrombophilia/antiphospholipid antibodies (p<0.05). The relative risk to develop pre-eclampsia was found to be 1.57 (1.34

PURPOSE: To describe the characteristics of mothers and children and to evaluate the factors associated with discontinuation of exclusive breastfeeding. METHODS: A cross-sectional study on infants under six months of age who attended the vaccination campaign in 2008. In the sample design, vaccination units were selected by drawing lots and infants were similarly selected later at each unit systematically. A semi-structured instrument was used for data collection, containing questions about children's nutrition and socio-demographic characteristics. We used Odds Ratio and the χ² test for data analysis, accepting as the critical level p<0.05. RESULTS: The prevalence of breastfeeding for infants under 120 and 180 days of age was 89.5 and 85% respectively, and exclusive breastfeeding was 50.6 and 39.7% for infants less than 120 and 180 days of age, respectively. The factors most related to the abandonment of exclusive breastfeeding in infants under six months were maternal employment outside the home (OR=2.73; 95%CI=1.74-4.29) and use of pacifiers (OR=4.26; 95%CI=2.85-6.38). The mother being multiparous (OR=0.57; 95%CI=0.40-0.81) and receiving postpartum care in the public health care network (OR=0.55; 95%CI=0.39-0.79) represented protective factors against the practice of early cessation of breastfeeding. CONCLUSIONS: The prevalence of breastfeeding and exclusive breastfeeding in the municipality of Uberlândia is among the highest in the country and the factors most often associated with the practice of early weaning were maternal employment outside the home, offering pacifiers to the infants, receiving postpartum care in the private health sector, and primiparity.

Preeclampsia, which affects about 3 to 5% of pregnant women, is the most frequent medical complication in pregnancy and the most important cause of maternal and perinatal morbidity and mortality. During the past three decades, numerous clinical, biophysical, and biochemical screening tests have been proposed for the early detection of preeclampsia. Literature shows large discrepancies in the sensitivity and predictive value of several of these tests. No single screening test used for preeclampsia prediction has gained widespread acceptance into clinical practice. Instead, its value seems to be in increasing the predictive value of panels of tests, which include other clinical measurements. The aim of this review was to examine the combination of maternal risk factors, mean arterial blood pressure, and uterine artery Doppler, together with biomarkers in the preeclampsia prediction.

PURPOSE: To describe the obstetric outcome of women with overweight/obesity treated at the prenatal care clinic of a public maternity hospital in Rio de Janeiro. METHODS: A descriptive cross-sectional study which investigated 433 women (³20 years-old, without any chronic diseases) and their newborns treated at public hospitals in Rio de Janeiro. Information was collected from medical records and through interviews. The characteristics of mothers and newborns evaluated were divided into maternal (social habits, anthropometric measurements and clinical, obstetric, and prenatal care) and newborn groups (birth conditions). Data regarding the categories of nutritional status were analyzed using the odds ratio (OR) and 95% confidence interval (CI). RESULTS: The prevalence of overweight/obesity in this sample was 24.5% (n=106). There was an association between inadequate weight gain and the prevalence of overweight/obesity (OR 2.7, 95%CI 1.5-4.9, p<0.05). Overweight/obese women had an increased risk for preeclampsia (OR 3.3, 95%CI 1.1--9.9, p=0.03). Regarding birth conditions, mean birth weight was 3291.3 g (±455.2), with rates of low birth weight of 4.7% (n=5) and rates of macrosomia of 2.8% (n=3). CONCLUSIONS: There was an alarming prevalence of inadequate nutritional status before and during pregnancy, which may be associated with increased risk of perinatal morbidity and mortality. This suggests the need for nutritional monitoring of these pregnant women.
