    Este trabalho teve como objetivos avaliar a validade de construto de uma versão do Female Sexual Function Index (FSFI). A versão foi inserida ao final de um questionário multidimensional e aplicada face a face em 235 mulheres esterilizadas. O índice de não resposta foi de 1,7%. A amostra apresentou-se bastante homogênea com baixa renda e nível educacional. Um coeficiente alfa de Cronbach de 0,948 indicou uma consistência interna muito alta. A análise fatorial demonstrou que o instrumento parece medir quatro fatores latentes: desejo/excitação, lubrificação, orgasmo/satisfação e dor. Isso pode referir-se a uma característica do próprio instrumento, às características da resposta sexual feminina ou ainda às peculiaridades culturais da amostra, o que pode interferir no entendimento das perguntas ou dos conceitos sobre os quais o instrumento versa. Assim aponta-se para necessidade de desenvolvimento de outros estudos na população geral para a definição do conjunto de propriedades do FSFI, como sua composição de fatores latentes e o estabelecimento de pontos de corte adequados à população brasileira.This study aimed to evaluate the construct validity of a version of the Female Sexual Function Index (FSFI). The version was inserted into a multidimensional questionnaire and applied face-to-face to 235 sterilized women. Non-response rate was 1.7%. The sample proved to be highly homogeneous, with low income and education. Cronbach's alpha of 0.948 indicated high internal consistency. Factor analysis showed that the instrument was measuring four factors: desire/arousal, lubrication, orgasm/satisfaction, and pain. This may reflect characteristics of the instrument itself, female sexual response, or even the sample's cultural peculiarities, which can affect understanding of the questions or concepts with which the instrument deals. This study emphasizes the need for further research in the general population to determine the psychometric properties of the FSFI, such as its factor composition and definition of appropriate cut-off points for the Brazilian population.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

    Ainda hoje pouco se conhece sobre a epidemiologia das disfunções sexuais femininas. O Female Sexual Function Index (FSFI) [Índice de Função Sexual Feminina] é um questionário breve, que pode ser auto-aplicado, e que se propõe avaliar a resposta sexual feminina. Este estudo teve por objetivo avaliar a adaptação transcultural da versão em português do FSFI. O processo envolveu cinco etapas: tradução, versão, apreciação formal de equivalência, revisão crítica por especialistas em sexualidade e pré-teste do instrumento. Após a identificação de problemas semânticos, concordâncias e discordâncias, foi possível propor uma versão sintética, escolhendo e incorporando itens de uma das duas versões em português. Algumas mudanças foram realizadas após o pré-teste do questionário, para tornar a versão em português mais coloquial e aceitável para a população-alvo ao utilizar termos mais corriqueiros, como opção ou complemento à linguagem científica. Ao se comparar mais de uma versão do instrumento, no processo de equivalência transcultural, foi possível detectar problemas e dificuldades na adaptação da linguagem que poderiam ter passado despercebidos, caso não se observassem todas as fases do processo.The epidemiology of female sexual dysfunctions is still not well known. The Female Sexual Function Index (FSFI) is a short questionnaire specially designed to assess female sexual response. This study aimed to evaluate the cross-cultural equivalence of the Portuguese version of the FSFI. The cross-cultural adaptation involved five steps: translation, back-translation, formal equivalence assessment, review by specialists in sexuality, and pre-testing. After identification of semantic problems, agreements, and disagreements, a brief version was proposed, selecting and incorporating items from one of the two Portuguese versions. Some changes were made after pre-testing the questionnaire, most of which to make the Portuguese version more readily comprehensible and acceptable for the target population, using ordinary words as options or to complement the scientific language. Comparing more than one version of the instrument in the process of cross-cultural equivalence allowed detecting problems and difficulties in adapting the language, which would not have been observed otherwise

    To evaluate the level of information possessed by pregnant adolescents regarding the human papillomavirus (HPV). Methods Descriptive study developed in the adolescent prenatal outpatient clinic of a tertiary hospital from the state of 55o Paulo, Brazil. Data were collected between June and December 2017 following approval from the ethics and research committee (CAAE: 1.887.892/2017). Pregnant adolescents, <= 18 years old, who attended the abovementioned outpatient section, composed the sample. Those diagnosed with a psychiatric disorder and those with hearing or cognitive disabilities were excluded. After acceptance to participate in the present study, the pregnant adolescents signed an Informed Consent Form. Regarding the statistical analysis, the chi-squared test and the Fisher exact test were used. Results Regarding the knowledge about HPV, 123 (80.92%) of the participants had already heard about the subject; for 77 (50.66%), their schools had been the source of the information; 101 (66.45%) did not know how they could be infected by the virus. Age variation did not influence their knowledge on how to prevent themselves from HPV (p = 0.2562). The variable vaccine is associated with HPV prevention (p < 0.0001). Conclusion The pregnant adolescents composing the sample have shown to have knowledge about HPV. However, they do not prevent themselves from it appropriately, given that little more than half of the sample was vaccinated, had not reported an understanding that the use of preservatives and vaccination are effective means of prevention, and did not correlate HPV with uterine cervical cancer415291297Avaliar o nível de informação que as adolescentes gestantes possuem em relação ao papilomavírus humano (HPV). Métodos Estudo descritivo desenvolvido no ambulatório pré-natal adolescente de um hospital terciário do estado de São Paulo, Brasil. Os dados foram coletados entre junho e dezembro de 2017, após a aprovação do comitê de ética e pesquisa (CAAE: 1.887.892/2017). A amostra foi composta por adolescentes gestantes com 18 anos que frequentaram o ambulatório. Foram excluídas as com transtorno psiquiátrico diagnosticado e as portadoras de deficiência auditiva ou de cognição. Após aceitarem participar do presente estudo, as adolescentes grávidas assinaram o termo de assentimento e consentimento livre e esclarecido. Para as análises estatísticas, foram utilizados os testes de qui-quadrado e exato de Fisher. Resultados Em relação ao conhecimento sobre o HPV, 123 (80,92%) já tinham ouvido falar sobre o assunto; destas adolescentes, 77 (50,66%) receberam as informações que tinham através de suas escolas, e 101 (66,45%) pacientes não sabiam como poderiam contrair o vírus. A variação da idade das adolescentes entrevistadas não influenciou se estas sabiam ou não como se prevenir contra o HPV (p ¼ 0,2562). A variável vacina está associada à prevenção contra o HPV (p < 0,0001). Conclusão As gestantes avaliadas possuem conhecimento sobre o HPV, mas não fazem a prevenção adequada, visto que um pouco mais da metade se vacinaram, não relataram o preservativo e a vacina como métodos eficazes de prevenção, e não relacionaram o HPV com o câncer de colo de útero

    To assess quality of care of women with severe maternal morbidity and to identify associated factors. This is a national multicenter cross-sectional study performing surveillance for severe maternal morbidity, using the World Health Organization criteria. The expected number of maternal deaths was calculated with the maternal severity index (MSI) based on the severity of complication, and the standardized mortality ratio (SMR) for each center was estimated. Analyses on the adequacy of care were performed. 17 hospitals were classified as providing adequate and 10 as nonadequate care. Besides almost twofold increase in maternal mortality ratio, the main factors associated with nonadequate performance were geographic difficulty in accessing health services (P < 0.001), delays related to quality of medical care (P = 0.012), absence of blood derivatives (P = 0.013), difficulties of communication between health services (P = 0.004), and any delay during the whole process (P = 0.039). This is an example of how evaluation of the performance of health services is possible, using a benchmarking tool specific to Obstetrics. In this study the MSI was a useful tool for identifying differences in maternal mortality ratios and factors associated with nonadequate performance of care.To assess quality of care of women with severe maternal morbidity and to identify associated factors.

    Assessment of human nutrition is a complex process, in pregnant women identify dietary patterns through mean nutrient consumption can be an opportunity to better educate women on how to improve their overall health through better eating. This exploratory study aimed to identify a posteriori dietary patterns in a cohort of nulliparous pregnant women. The principal component analysis (PCA) technique was performed, with Varimax orthogonal rotation of data extracted from the 24-h dietary recall, applied at 20 weeks of gestation. We analysed 1.145 dietary recalls, identifying five main components that explained 81% of the dietary pattern of the sample. Dietary patterns found were: Obesogenic, represented by ultra-processed foods, processed foods, and food groups rich in carbohydrates, fats and sugars; Traditional, most influenced by natural, minimally processed foods, groups of animal proteins and beans; Intermediate was similar to the obesogenic, although there were lower loads; Vegetarian, which was the only good representation of fruits, vegetables and dairy products; and Protein, which best represented the groups of proteins (animal and vegetable). The obesogenic and intermediate patterns represented over 37% of the variation in food consumption highlighting the opportunity to improve maternal health especially for women at first mothering

    Objective: To assess the calorie intake and nutritional content of the maternal diet in regions with different culinary traditions and typical foods, and to understand the nutritional profile so as to provide information about the consumption of this population and promote maternal and perinatal health. Methods: From a cohort of 1145 pregnant women with diverse socio-backgrounds we analyzed the dietary characteristics profile according to three guidelines and compared the differences between regions of Brazil. Results: Women from the northeast had the lowest level of income, occupation, education, and age (P < 0.001). Intakes of unprocessed/minimally processed foods and processed foods were more prevalent in women from the northeast than in southern/southeastern women (P < 0.001). The consumption of dairy products and vegetables was less than the recommended intake, with lower intake in southern/southeastern women (P < 0.001). This study showed a lower consumption of dairy and vegetables, with a shortfall of vitamins K and D, iron, calcium, folate, magnesium, and chromium from natural and fortified foods. We observed a greater consumption of unprocessed or minimally processed food in women from the northeast of Brazil. Conclusion: Our findings indicate the importance of differentiating the source of calorie intake between regional nutritional guidance and the diversity of local cuisine

    Proposal of MUAC as a fast tool to monitor pregnancy nutritional status : results from a cohort study in Brazil

    Objective: In Brazil, although the assessment of maternal nutritional status is recommended using body mass index (BMI), this is only possible in settings adequately prepared. Midupper arm circumference (MUAC) is another biological variable identified as a tool for rapid assessment of nutritional status that is correlated with BMI. Therefore, we aim to surrogate BMI by MUAC cut-offs for rapid screening of maternal nutritional status starting at midpregnancy. Design: Analysis of the multicentre cohort study entitled ‘Preterm SAMBA’ using an approach of validation of diagnostic test. Setting: Outpatient prenatal care clinics from five tertiary maternity hospitals from three different Brazilian regions. Participants: 1165 pregnant women attending prenatal care services from 2015 to 2018 and with diverse ethnic characteristics who were enrolled at midpregnancy and followed in three visits at different gestational weeks. Primary and secondary outcome measures: Sensitivity, specificity, positive and negative predictive values, likelihood ratio and accuracy of MUAC being used instead of BMI for the assessment of nutritional status of women during pregnancy. Results: We found a strong correlation between MUAC and BMI, in the three set points analysed (r=0.872, 0.870 and 0.831, respectively). Based on BMI categories of nutritional status, we estimated the best MUAC cut-off points, finding measures according to each category: underweight 30.15 cm (19–21 weeks), >30.60 cm (27–29 weeks) and >30.25 cm (37–39 weeks) per gestational week. Therefore, we defined as adequate between 25.75–28.10 cm (19–21 weeks), 25.75–28.70 cm (27–29 weeks) and 25.75–29.45 cm (37–39 weeks) of MUAC. Conclusion: We conclude that MUAC can be useful as a surrogate for BMI as a faster screening of nutritional status in pregnant women

    Head circumference as an epigenetic risk factor for maternal nutrition

    Nutrition indicators for malnutrition can be screened by many signs such as stunting, underweight or obesity, muscle wasting, and low caloric and nutrients intake. Those deficiencies are also associated with low socioeconomic status. Anthropometry can assess nutritional status by maternal weight measurements during pregnancy. However, most studies have focused primarily on identifying changes in weight or Body Mass Index (BMI), and their effects on neonatal measures at present time. Whereas head circumference (HC) has been associated with nutrition in the past. When the mother was exposed to poor nutrition and unfavorable social conditions during fetal life, it was hypothesized that the intergenerational cycle was potentially mediated by epigenetic mechanisms. To investigate this theory, maternal head circumference (MHC) was associated with neonatal head circumference (NHC) in pregnant women without preexisting chronic conditions, differentiated by sociodemographic characteristics. A multiple linear regression model showed that each 1 cm-increase in MHC correlated with a 0.11 cm increase in NHC (β95% CI 0.07 to 0.15). Notwithstanding, associations between maternal and neonatal anthropometrics according to gestational age at birth have been extensively explained. Path analysis showed the influence of social status and the latent variable was socioeconomic status. A model of maternal height and head circumference was tested with effects on neonatal HC. The social variable lacked significance to predict neonatal HC in the total sample (p = 0.212) and in the South/Southeast (p = 0.095), in contrast to the Northeast (p = 0.047). This study highlights the potential intergenerational influence of maternal nutrition on HC, suggesting that maternal nutrition may be more relevant in families with major social vulnerability

    Planning, implementing, and running a multicentre preterm birth study with biobank resources in Brazil : the preterm SAMBA study

    Background. Our aim was to describe the steps in planning, implementing, and running a multicentre cohort study of maternal and perinatal health using a high-quality biobank comprised of maternal serum, plasma, and hair samples collected from five sites in Brazil.The Preterm SAMBA study, conducted by the Brazilian Network for Studies on Reproductive and Perinatal Health, was an innovative approach used to identify women at higher risk for preterm birth. It is also of great importance in the study of other maternal and perinatal complications in the context of Brazil, which is a middle-income country. Methods. We described phases of planning, implementing, and running the Preterm SAMBA study, a multicentre Brazilian cohort study of low-risk nulliparous pregnant women, to validate a set of metabolite biomarkers for preterm birth identified in an external cohort. Procedures and strategies used to plan, implement, and maintain this multicentre preterm birth study are described in detail. Barriers and experience cited in the current narrative are not usually discussed in the scientific literature or published study protocols. Results. Several barriers and strategies were identified in different phases of the Preterm SAMBA study at different levels of the study framework (steering committee; coordinating and local centres). Strategies implemented and resources used in the study are a legacy of the Brazilian Network, aimed at training collaborators in such complex settings. Conclusion. The Brazilian Network for Studies on Reproductive and Perinatal Health has gained some experience in conducting a multicentre cohort study using a resourceful biobank which may be helpful to other research groups and maternal/perinatal health networks that plan on employing a similar approach to a similar background
