Post-Traumatic Stress Disorder in Brazilian Pregnant Women at the Beginning of the Coronavirus Disease Pandemic.

OBJECTIVE: Analyze the presence of PTSD symptoms and their risk among the pregnant women during the COVID-19 pandemic. METHODS: This is a cross-sectional study of pregnant women that received receiving prenatal care at two university hospitals in São Paulo, Brazil, during the COVID-19 pandemic, from April to June 2020. The sociodemographic and health data of the participants and their exposure to individuals suspected or confirmed to have COVID-19 were evaluated. The Impact of Event Scale-Revised and the State-Trait Anxiety Inventory were used to assess PTSD and anxiety symptoms, respectively. RESULTS: A total of 149 pregnant women were included in this study. The risk of PTSD among the participants was 55.1%. The independent risk factors for PTSD were state anxiety (ORadj = 2.6), trait anxiety (ORadj = 10.7), changes in routine due to the pandemic (ORadj = 4.7) and contact with a confirmed case of COVID-19 person (ORadj = 7.1). CONCLUSIONS: The COVID-19 pandemic had a significant negative impact on the mental health of pregnant women, more than half of the participants of the present study showed a risk of PTSD, exacerbated by anxiety symptoms and exposure to individuals with a confirmed case of COVID-19.

Bacterial profile and prevalence of urinary tract infections in pregnant women in Latin America: a systematic review and meta-analysis.

BACKGROUND: Given the physiological changes during pregnancy, pregnant women are likely to develop recurrent urinary tract infections (UTIs) and pyelonephritis, which may result in adverse obstetric outcomes, including prematurity and low birth weight preeclampsia. However, data on UTI prevalence and bacterial profile in Latin American pregnant women remain scarce, necessitating the present systematic review to address this issue. METHODS: To identify eligible observational studies published up to September 2022, keywords were systematically searched in Medline/PubMed, Cochrane Library, Embase, Web of Science, and Bireme/Lilacs electronic databases and Google Scholar. The systematic review with meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the quality of studies was classified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The meta-analysis employed a random-effects method with double-arcsine transformation in the R software. RESULTS: Database and manual searches identified 253,550 citations published until September 2022. Among the identified citations, 67 met the inclusion criteria and were included in the systematic review, corresponding to a sample of 111,249 pregnant women from nine Latin American countries. Among Latin American pregnant women, the prevalence rates of asymptomatic bacteriuria, lower UTI, and pyelonephritis were estimated at 18.45% (95% confidence interval [CI]: 15.45-21.53), 7.54% (95% CI: 4.76-10.87), and 2.34% (95% CI: 0.68-4.85), respectively. Some regional differences were also detected. Among the included studies, Escherichia coli (70%) was identified as the most frequently isolated bacterial species, followed by Klebsiella sp. (6.8%). CONCLUSION: Pregnant women in Latin America exhibit a higher prevalence of bacteriuria, UTI, and pyelonephritis than pregnant women globally. This scenario reinforces the importance of universal screening with urine culture during early prenatal care to ensure improved outcomes. Future investigations should assess the microbial susceptibility profiles of uropathogens isolated from pregnant women in Latin America. TRIAL REGISTRATION: This research was registered at PROSPERO (No. CRD42020212601).

Fertility specialists' views, behavior, and attitudes towards the use of endometrial scratching in Italy.

BACKGROUND: Endometrial scratching (ES) or injury is intentional damage to the endometrium performed to improve reproductive outcomes for infertile women desiring pregnancy. Moreover, recent systematic reviews with meta-analyses and randomized controlled trials demonstrated that ES is not effective, data on the safety are limited, and it should not be recommended in clinical practice. The aim of the current study was to assess the view and behavior towards ES among fertility specialists throughout infertility centers in Italy, and the relationship between these views and the attitudes towards the use of ES as an add-on in their commercial setting. METHODS: Online survey among infertility centers, affiliated to Italian Society of Human Reproduction (SIRU), was performed using a detailed questionnaire including 45 questions with the possibility to give "closed" multi-choice answers for 41 items and "open" answers for 4 items. Online data from the websites of the infertility centers resulting in affiliation with the specialists were also recorded and analyzed. The quality of information about ES given on infertility centers websites was assessed using a scoring matrix including 10 specific questions (scored from 0 to 2 points), and the possible scores ranged from 0 to 13 points ('excellent' if the score was 9 points or more, 'moderate' if the score was between 5 and 8, and 'poor' if it was 4 points or less). RESULTS: The response rate was of 60.6% (43 questionnaires / 71 infertility SIRU-affiliated centers). All included questionnaires were completed in their entirety. Most physicians (~ 70%) reported to offer ES to less than 10% of their patients. The procedure is mainly performed in the secretory phase (69.2%) using pipelle (61.5%), and usually in medical ambulatory (56.4%) before IVF cycles to improve implantation (71.8%) without drugs administration (e.g., pain drugs, antibiotics, anti-hemorrhagics, or others) before (76.8%) or after (64.1%) the procedure. Only a little proportion of infertility centers included in the analysis proposes formally the ES as an add-on procedure (9.3%), even if, when proposed, the full description of the indications, efficacy, safety, and costs is never addressed. However, the overall information quality of the websites was generally "poor" ranging from 3 to 8 and having a low total score (4.7 ± 1.6; mean ± standard deviation). CONCLUSIONS: In Italy, ES is a procedure still performed among fertility specialists for improving the implantation rate in IVF patients. Moreover, they have a poor attitude in proposing ES as an add-on in the commercial setting.

Clinical characteristics, complications, and predictive model of histological chorioamnionitis in women with preterm premature rupture of membranes.

We aimed to analyze the impact of histological chorioamnionitis (HCA) in the presence of preterm premature rupture of the membranes (PPROM) on obstetric and neonatal outcomes, and its possible predictability. A retrospective cohort analysis of PPROM cases (20-37 weeks) was conducted comparing the patients with and without HCA, seeking a predictive model of HCA using logistic regression. A total of 295 cases of PPROM were selected, of which 72 (24.4%) had HCA. The group with HCA had a shorter latency period and a greater number of clinical and laboratory criteria in the evolution. The group with HCA had a worse comparative result and presented: lower gestational age at delivery, lower average birth weight, lower Apgar scores, longer neonatal hospitalization, worse maternal clinical conditions and, higher rates of stillbirth, low birth weight (LBW), very low birth weight (VLBW), complications in pregnancy and childbirth, and cesarean delivery due to fetal distress or chorioamnionitis. A predictive model for HCA was developed, with the following independent variables: abdominal pain (odds ratio [OR] = 11.61), uterine activity (noticeable contractions on physical exam) (OR = 5.97), fever (OR = 5.77), latency > 3 days (OR = 2.13), and C-reactive protein (OR = 1.01). With this model, an adequate receiver operating characteristic curve was found, with an area under the curve of 0.726, and some HCA probability curves were constructed for different clinical situations. In this novel study, we present a non-invasive predictive model, with clinical and laboratory variables, which may help in decision-making in a patient with PPROM.

Adverse Perinatal Outcomes among Adolescent Pregnant Women Living with HIV: A Propensity-Score-Matched Study.

HIV infection and adolescent pregnancy are known to increase the risk of adverse perinatal outcomes. However, data are limited concerning the outcomes of pregnancies among adolescent girls living with HIV. This retrospective propensity-score matched study aimed to compare adverse perinatal outcomes in adolescent pregnant women living with HIV (APW-HIV-positive) with HIV-negative adolescent pregnant women (APW-HIV-negative) and adult pregnant women with HIV (PW-HIV). APW-HIV-positive were propensity-score matched with APW-HIV-negative and PW-HIV. The primary endpoint was a composite endpoint of adverse perinatal outcomes, comprising preterm birth and low birth weight. There were 15 APW-HIV-positive and 45 women in each control group. The APW-HIV-positive were aged 16 (13-17) years and had had HIV for 15.5 (4-17) years, with 86.7% having perinatally acquired HIV. The APW-HIV-positive had higher rates of perinatally acquired HIV infection (86.7 vs. 24.4%, p < 0.001), a longer HIV infection time (p = 0.021), and longer exposure to antiretroviral therapy (p = 0.034) compared with the PW-HIV controls. The APW-HIV-positive had an almost five-fold increased risk of adverse perinatal outcomes compared with healthy controls (42.9% vs. 13.3%, p = 0.026; OR 4.9, 95% CI 1.2-19.1). The APW-HIV-positive and APW-HIV-negative groups had similar perinatal outcomes.

Prevalence of oncogenic human papillomavirus in pregnant adolescents, association with colpocytological changes, risk factors and obstetric outcomes.

PURPOSE: The authors aim to carry out an investigation on the impact of cervical oncogenic Human Papillomavirus (HPV) detection in pregnant adolescents, to clarify the prevalence and risk factors, considering the importance and lack of data on this topic in Brazil. METHODS: A cross-sectional study was conducted with adolescents receiving prenatal care in a tertiary hospital in São Paulo, Brazil, with routine Pap smear and oncogenic HPV detection test in the uterine cervix. The authors sought to associate the results of these tests with demographic and obstetric variables. RESULTS: A total of 303 pregnant adolescents whose mean age was 15.30 ± 1.22 years comprised the study subjects. The frequency of high-risk HPV cervical detection was 50.50%. Multivariate analysis revealed that a large number of partners in their lifetime (OR = 1.27) and having a religion (OR = 2.05) were risk factors for cervical detection of oncogenic HPV, while schooling appeared as a protective factor (OR = 0.85). There was an association between this detection and colpocytological alterations, reaching almost 30% of patients, but without association with obstetric and neonatal outcomes. CONCLUSION: The prevalence found is one of the highest in Brazil and worldwide. A greater number of partners during their lifetime and having religion were detected as possible factors associated with cervical HPV detection. Detection of cervical HPV-DNA did not influence obstetric and neonatal outcomes. The findings of this study reinforce the need to implement educational measures capable of modifying the incidence of sexually transmitted infections in this population and capable of promoting adherence to HPV vaccination programs.

Use of Mirtazapine and Olanzapine in the Treatment of Refractory Hyperemesis Gravidarum: A Case Report and Systematic Review.

Hyperemesis gravidarum (HG) is a rare condition (1.1%) characterized by excessive vomiting, malnutrition, dehydration, and laboratorial alterations. Herein, we describe the even rarer and serious presentation of refractoriness to the usual treatment of antiemetics and parenteral nutrition, with improvement only after the use of olanzapine and mirtazapine. Two subsequent pregnancies of the same woman with HG are described, which were associated with severe weight loss, anemia, hyponatremia, hypokalemia, and mild dysfunction of liver enzymes. In the third pregnancy, the usual treatment for HG was not successful, requiring enteral nutrition and the introduction of olanzapine. In the fourth pregnancy, the patient refused to use enteral nutrition for refractory HG. Hence, the patient was started on mirtazapine at an initial dose of 15 mg/day, which was gradually increased to 30 mg/day. The patient responded well to the new regimen, as demonstrated by the decrease in symptoms, the gain of 10 kg in the pregnancy, and delivering a healthy newborn. A systematic review of literature showed 11 articles and 30 cases that successfully used mirtazapine in HG. Good clinical outcomes were seen with 4 days of the treatment and at an initial dose of 15 mg/day. However, most of these reports were from psychiatric profiles, with a predominance of depression and anxiety symptoms, and a poor description of the obstetric conditions and the disease progression itself. Pulmonary hypertension was described in one case and neonatal hyperexcitability in another. The case described in this paper reinforces the idea that mirtazapine and olanzapine can be considered in refractory HG, with good results. In the world literature, this is the second case of HG that has been successfully treated with olanzapine and the first in Latin America treated with mirtazapine.

Weight loss among pregnant women hospitalized because of hyperemesis gravidarum: Is there a lack of nutrition intervention?

BACKGROUND: Nutrition therapy is a key component in the management of hyperemesis gravidarum (HG). The aim of this study was to describe sociodemographic, anthropometric, and nutrition aspects of pregnant women hospitalized because of HG and raise a discussion about the nutrition care provided. MATERIALS AND METHODS: This is a retrospective descriptive study that includes 26 pregnant women with confirmed diagnosis of HG who were hospitalized because of this condition in a tertiary hospital. Data of interest were collected from official medical records and analyzed to obtain measures of central tendency and dispersion, as well as frequencies. RESULTS: The studied individuals had a mean age of 25.7 years and a low level of education, and 65% of them were single mothers. They registered a low weight gain (2.8 kg) during pregnancy and in the course of their hospitalization, during which they lost an average of 1.7 kg, showing a decline in nutrition status during this period. Although the average intake of oral diet (OD) was 55% during hospital stay and only 5% of the studied population met caloric needs through OD, the prescription of complementary medical nutrition therapy (oral supplements, enteral or parenteral nutrition) was scarcely observed in this sample. CONCLUSION: Despite the negative impact that HG can impose on the mother's nutrition status and the known benefits that complementary nutrition therapies can provide, few nutrition interventions have been carried out to improve this situation. That indicates an urgent need for implementation or reviewing of nutrition assistance protocols for HG patients.

Postpartum depressive symptoms of Brazilian women during the COVID-19 pandemic measured by the Edinburgh Postnatal Depression Scale.

BACKGROUND: The COVID-19 pandemic gave rise to concerns about its potential impact on the mental health of pregnant and postpartum women as the general postpartum depression rates increased. METHODS: Three postpartum questionnaires (Edinburgh Postnatal Depression Scale - EPDS; Anxiety and Depression Scale - HAD; and a demographic questionnaire about isolation and information acquisition) were used to evaluate the mental health of women with and without COVID-19 and determine the factors associated with depressive symptoms (EPDS ≥ 12). RESULTS: Data from 184 participants with a mean of 56 postpartum days were analyzed. The rate of symptoms compatible with postpartum depression (PPD) was 38.8%, with a 14.3% positive response to item 10 on the EPDS (suicidal ideation - SI). Listening to the news about COVID-19 averaged 4.45 hours a day. Factors related to PPD were concerns about lack of hospital beds (OR = 2.45), absence of a partner (OR = 2.70), and anxiety symptoms (OR = 10). Factors related to SI were anxiety symptoms (OR = 1.56) and friends as a source of information (OR = 5.60). LIMITATIONS: Considering the rapidly changing epidemiological conditions of this pandemic, this study may only be the photograph of an instant. CONCLUSIONS: Higher rates of PPD in the Brazilian population are related not only to anxiety but also to an inadequate family environment, kind of information acquisition and concerns about the lack of hospital beds.

Bacteriuria in Pregnant Adolescents and Behavioral Risk Factors: A Cross-Sectional Study at a Brazilian Teaching Hospital.

INTRODUCTION: Bacteriuria during pregnancy is a frequent and important cause of morbidity and complications. Data on its occurrence in pregnant adolescents are still scarce. METHODS: A cross-sectional study was conducted at a tertiary teaching hospital in São Paulo, Brazil. All adolescents (≤18 years) who came for prenatal care between January 2010 and January 2016 were included. Sociodemographic characteristics, medical history, obstetric history, and the results of laboratory tests were selected. A urine sample was aseptically collected from each patient to undergo microscopic and culture analysis. RESULTS: A total of 388 pregnant adolescents averaging 15.30 ± 1.24 years of age were included. The frequency of bacteriuria in this group was 17.01% (66/388). The lack of sports practice (OR = 8.65; 95% CI, 1.09-68.39), the fact that pregnancy was desired (OR = 2.17; 95% CI, 1.08-4.34), and the use of hormonal methods of contraception (OR = 2.46; 95% CI, 1.04-5.84) turned out to be independent risk factors for bacteriuria. Protective factors were identified as late coitarche (OR = 0.75; 95% CI, 0.57-0.98) and a urine culture analysis at a later gestational age (OR = 0.94; 95% CI, 0.90-0.98). The most often isolated pathogens were Escherichia coli (49%) and Streptococcus agalactiae (18%). CONCLUSION: Bacteriuria among pregnant adolescents is a relatively common condition. The infection risk of the urinary tract was increased by physical inactivity and seemingly by the influence of behavioral and sexual factors. Such results can help to identify patients at risk, favoring the early diagnosis of urinary tract infections and optimizing prenatal care.

Urinary Bacterial Profile and Antibiotic Susceptibility in Pregnant Adolescents and Pregnant Low Obstetric Risk Adult Women.

INTRODUCTION: Significant bacteriuria is associated with clinical and obstetric complications. The existing studies on the profile of urinary pathogens in pregnant women have widely divergent results and they hardly include data on pregnant adolescents. METHODS: This observational retrospective study was conducted in a tertiary hospital in the city of São Paulo with 388 pregnant adolescents and 2547 pregnant low-risk obstetric care adults who began prenatal care between January 2010 and January 2016. They were compared in terms of urine sediment, urine culture, and antibiogram results. RESULTS: The prevalence of bacteriuria was 17.01% (66/388) among adolescents and 10.13% (258/2547) among adults. Adolescence was a risk factor for bacteriuria in pregnancy (OR=1.82, CI95%=1.35-2.44, p=0.08). The most frequently isolated pathogen in urine culture was Escherichia coli, both in adolescents (49%) and in adults (42.18%). In positive urine cultures, urinary leukocytes were present in greater numbers in adolescents than in adults (p<0.001). Resistance to quinolones in general was more frequent among adults (OR=5.86, CI95%=0.78-44.20, p<0.001), but the tendency was not statistically significant. CONCLUSION: Escherichia coli and the less frequent Streptococcus agalactiae were the etiologic agents most often found in the urine cultures both of adolescents and adults. Higher rates of bacteriuria and of abnormal urine sediments prevailed among adolescents.

Epidemiological profile of patients with preterm premature rupture of membranes at a tertiary hospital in São Paulo, Brazil.

OBJECTIVE: To perform a descriptive analysis of preterm premature rupture of membranes (PPROM) cases attended in a tertiary hospital. METHOD: Retrospective analysis of medical records and laboratory tests of patients admitted to a Brazilian tertiary hospital between 2006 and 2011, with a confirmed diagnosis of PPROM and gestational age (GA) at delivery <37 weeks. RESULTS: A total of 299 pregnant women were included in the study. Nine patients evolved to abortion, and 290 pregnant women remained for the final analysis. There was initial diagnostic doubt in 17.6% of the cases. The oligohydramnios rate [amniotic fluid index (AFI) <5] was 27.9% on admission. Chorioamnionitis was initially diagnosed in 10.8% of the patients and was retrospectively confirmed in 22.9% of the samples. The latency period had a mean of 9.1 days. The main reasons for interruption were premature labor (55.2%), GA ≥36 weeks (27.2%), and fetal distress (6.9%). The delivery method was cesarean section in 55% of cases. The mean birth weight was 2,124 grams, and 67% of the neonates had a low birth weight (<2500 g). The GA at delivery averaged 33.5 weeks. The stillbirth rate was 5.3%, and the early neonatal mortality rate was 5.6%. There were complications at delivery in 18% of mothers. CONCLUSION: In one of the few Brazilian reports on the epidemiological profile of PPROM, with GA until 37 weeks and intercurrences generally excluded from assessments (such as twinning and fetal malformations), there is a favorable evolution, with an acceptable rate of complications.

Maternal nutrient intake and fetal gastroschisis: A case-control study.

Fetal gastroschisis is a paraumbilical abdominal wall defect with herniation of the abdominal organs. This multifactorial malformation occurs in young pregnant women, and the underlying cause of the disease remains unknown; however, nutritional factors may play a role in its development. This case-control study explored the association of maternal nutrient intake with the occurrence of gastroschisis. The gastroschisis group (GG) comprised 57 pregnant women with fetuses with gastroschisis, and the control group (CG) comprised 114 pregnant women with normal fetuses matched for maternal age, gestational age, and preconception body mass index classification. Nutritional assessments related to the preconception period were obtained using the food consumption frequency questionnaire, and nutrient intakes were calculated using nutrition programs. The median daily calorie intake was higher (2,382.43 vs. 2,198.81; p = .041) in the GG than in the CG. The median intake of methionine (763.89 vs. 906.34; p = .036) and threonine (1,248.34 vs. 1,437.01; p = .018) was lower in the GG than in the CG. Pregnant women with fetuses with gastroschisis have a diet characterized by higher calorie intake and lower levels of essential amino acids (methionine and threonine) during the preconception period than pregnant women with normal fetuses.

Comparative analysis of Insulin-like growth factor binding protein-1, placental alpha-microglobulin-1, phenol and pH for the diagnosis of preterm premature rupture of membranes between 20 and 36 weeks.

AIM: Preterm premature rupture of membranes (PPROM) is responsible for approximately one-third of premature births worldwide, and although the diagnosis is often straightforward, this condition can still present difficulties. The purpose of this research was to compare the accuracy of several PPROM diagnostic tests. METHODS: A total of 94 pregnant women with clinical suspicion of PPROM who were between 20 and 36 weeks of pregnancy were examined by vaginal speculum, and tests were performed for phenol, pH, insulin-like growth factor binding protein-1 (IGFBP-1) and placental alpha-microglobulin-1 (PAMG-1). All patients were followed up until the diagnosis was fully defined, and a diagnosis of PROM was confirmed by a definitive evolution of the clinical symptoms (visualization of vaginal amniotic fluid or persistence of oligohydramnios). RESULTS: After excluding the cases that could not be definitively diagnosed, a good diagnostic performance of the immunochromatographic tests was observed that was superior to that of the clinical tests. Similar accuracies were observed for IGFBP-1 (98.7%) and PAMG-1 (93.9%). However, while the IGFBP-1 test differed from a vaginal pH ≥7 (88.9%) and the phenol test (85.7%), this did not occur for the PAMG-1 test. The performance of the tests was modified only by the presence of bleeding (with lower specificity rates for pH and phenol), without interference of gestational age or maternal morbidities. CONCLUSION: Immunochromatographic tests are good tools but should be used sparingly in resource-poor settings because they are expensive, and there is no significant difference between PAMG-1 and traditional tests.

Determination of nighttime salivary cortisol during pregnancy: comparison with values in non-pregnancy and Cushing's disease.

PURPOSE: Nighttime salivary cortisol (NSC) has been proposed for the diagnosis of Cushing's syndrome during pregnancy. However, reference values for NCS in pregnant women have not been adequately determined. The aim of this study was to determine the reference values of NSC in the three gestational trimesters in order to help distinguish physiological from pathological hypercortisolism during pregnancy. METHODS: This prospective and retrospective study evaluated 85 pregnant women in whom samples were collected in the first, second and/or third gestational trimester (pregnancy group), 33 non-pregnant women (control group), and 25 non-pregnant women with Cushing's disease (CD group). NSC was measured by enzyme-linked immunosorbent assay. RESULTS: NSC increased progressively during pregnancy, reaching maximum levels on the third trimester (median 2.1-fold increase compared with controls, p < 0.001). Reference values for NSC were determined and the upper limits on each gestational trimester were: first trimester 0.25 µg/dL (6.9 nmol/L), second trimester 0.26 µg/dL (7.2 nmol/L), and third trimester 0.33 µg/dL (9.1 nmol/L). Cutoff values that separated the CD group from the three trimesters in the pregnancy groups were, respectively, 0.255 µg/dL (7.0 nmol/L), 0.260 µg/dL (7.2 nmol/L), and 0.285 µg/dL (7.9 nmol/L). Comparison of NSC cutoff values in pregnant women with CD patients showed high sensitivity and specificity in all three trimesters. CONCLUSIONS: We established cutoff values for determination of NSC which can be useful for pregnant women with a diagnostic suspicion of CD.

[Cross-cultural adaptation of the Pregnancy and Weight Gain Attitude Scale]. / Adaptação transcultural da Escala de Atitudes em Relação ao Ganho de Peso na Gestação.

PURPOSE: To present the cross-cultural adaptation to Brazilian Portuguese language of the Pregnancy and Weight Gain Attitude Scale. METHODS: This scale was developed in order to verify whether attitude toward thinness affects weight gain during pregnancy and contains statements that express different attitudes of pregnant women regarding their own weight gain. The procedures were: translation, back translation, comprehension evaluation, preparation of a final version, application of the scale to 180 pregnant women (mean age=29.6, gestational age=25.7 weeks) and psychometric analysis. RESULTS: Satisfactory equivalence between the versions and satisfactory internal consistency (Cronbach's alpha 0.7) were detected. The exploratory factor analysis suggested four subscales with 51.4% total variance explained. CONCLUSION: The scale proved to be valid and can be used in studies with pregnant women in Brazil to assess attitudes toward weight gain and to detect and prevent dysfunctional behaviors during pregnancy.

Adaptação transcultural da Escala de Atitudes em Relação ao Ganho de Peso na Gestação / Cross-cultural adaptation of the Pregnancy and Weight Gain Attitude Scale

OBJETIVO: Apresentar a adaptação transcultural para o português da Escala de Atitudes em Relação ao Ganho de Peso na Gestação. MÉTODOS: Essa escala, que contém afirmações que expressavam diferentes atitudes de gestantes em relação ao seu próprio ganho de peso, foi desenvolvida para determinar se as atitudes em relação ao corpo afetariam o ganho de peso durante a gestação. Os procedimentos foram: tradução, retrotradução, avaliação da compreensão, elaboração de versão final, aplicação da escala em 180 gestantes (média 29,6 anos e idade gestacional 25,7 semanas) e análise psicométrica. RESULTADOS: Constatou-se equivalência satisfatória entre as versões inglês-português e boa consistência interna (Alpha de Cronbach 0,7). A análise fatorial exploratória sugeriu quatro subescalas com variância total explicada de 51,4%. CONCLUSÃO: A escala se demonstrou válida e pode ser utilizada em estudos com gestantes no Brasil para avaliação de atitudes em relação ao ganho de peso e detecção e prevenção de comportamentos disfuncionais durante a gestação. .
