Metabolic syndrome in women with breast cancer: scope review / Síndrome metabólica em mulheres com câncer de mama: revisão de escopo

Objective: To synthesize evidence involving pathophysiological and clinical-epidemiological linking mechanisms in women with breast cancer and metabolic syndrome. Method: This is a structured scoping review according to the Joanna Briggs Institute and was conducted in the PubMed, BDENF, LILACS, IBECS, CUMED, WPRIM, BINACIS, and Embase databases. This review is registered in the Open Science Framework. Result: Regarding the level of evidence of the included studies, moderate and strong evidence levels were predominant. There were no weak evidence findings in this research. The chronic inflammatory state of breast adipose tissue in patients with obesity can worsen the negative impact on cancer cells, directly affecting survival and recurrence. Unexplained weight gain or loss is associated with shorter survival in women with breast cancer, highlighting the need for specific guidance during treatment. Conclusion: Metabolic syndrome is associated with the risk of breast cancer; however, massive weight loss during active disease can be associated with a worse prognosis and should therefore be prevented. Patients should be advised to maintain a stable weight during chemotherapy and to receive guidance on adequate nutrition and physical activity to increase muscle mass

Objetivo: Sintetizar as principais evidências envolvendo os mecanismos de ligação fisiopatológico e clínico-epidemiológico em mulheres com câncer de mama e a síndrome metabólica. Método: Trata-se de uma revisão de escopo estruturada conforme o Instituto Joanna Briggs, realizado nas bases de dados PubMed, BDENF, LILACS, IBECS, CUMED, WPRIM, BINACIS e Embase. Esta revisão encontra-se protocolada no Open Science Framework. Resultado: Com relação ao nível de evidência dos estudos inclusos, houve predominância para níveis fortes de evidência. Não houve achados de evidência fraca nesta pesquisa. O estado inflamatório crônico do tecido adiposo mamário em casos de obesidade pode agravar o impacto negativo nas células cancerígenas, afetando diretamente a sobrevida e recorrência. Ganho ou perda de peso inexplicável estão associados a uma menor sobrevida em mulheres com câncer de mama, sublinhando a necessidade de orientações específicas durante o tratamento. Conclusão: A síndrome metabólica esta associada ao risco de câncer de mama, entretanto, a perda maciça de peso durante a doença ativa pode ser um fator de pior prognóstico, devendo assim, ser realizada de forma preventiva. Os pacientes devem ser orientados a manter um peso estável durante a quimioterapia e receber orientações sobre alimentação adequada e atividade física em busca de aumento de massa muscular

Evaluation de la qualité de vie après mastectomie pour cancer du sein au CHU Gabriel Touré / Evaluation of the quality of life after mastectomy for breast cancer at the Gabriel Touré university hospital

Les thérapeutiques oncologiques entraînent des répercussions sur la qualité de vie des patientes. Cette qualité de vie constitue un élément cardinal dans le parcours de soins de malades. Nous avons initié ce travail pour évaluer la qualité de vie après mastectomie. Matériel et méthode : Nous avons réalisé une étude transversale descriptive sur une période de 5ans allant de janvier 2016 à décembre 2020 au service de chirurgie générale au CHU Gabriel Touré. Nous avons inclus tous les patients opérés pour cancer du sein avec preuve histologique et ayant subi une mastectomie et acceptant de répondre au questionnaire. Résultat : Le questionnaire QLQC3O est une échelle spécifique au cancer utilisée pour établir le score sur la qualité de vie comme beaucoup d'autres mais à la différence d'être plus simple, facile d'utilisation et plus utilisé. Nous avons enregistré 79 cas de mastectomie pour cancer du sein. La prévalence de la mastectomie était de 5,8%. L'âge médian était de 58 ans. Les patientes avaient au moins un enfant dans 92,38%. Le carcinome canalaire de type non spécifique était le type histologique le plus fréquent avec 87,33%.Les effets secondaires de la mastectomie affectent le domaine des symptômes ont constitué l'étape la plus difficile à supporter avec p value non significatif. Ces situations ont sérieusement affecté l'estime de soi. Parmi les effets secondaires affectant la qualité de vie (52 cas), les troubles digestifs (22 cas) étaient au 1er plan suivis de dyspnée (7 cas) et des difficultés financières (8 cas) qui ont abouti à la vente de biens. Conclusion : La place de la qualité de vie reste incontestable dans la stratégie thérapeutique et son évaluation améliore quant au choix thérapeutique.

Oncology therapies have repercussions on the quality of life of patients. This quality of life is a cardinal element in the care pathway of patients. We initiated this work to assess the quality of life after mastectomy. Material and method: We carried out a descriptive cross-sectional study over a period of 5 years from January 2016 to December 2020 in the General Surgery Department of the Gabriel Touré University Hospital. We included all patients who had undergone surgery for breast cancer with histological evidence and who had undergone a mastectomy and agreed to answer the questionnaire. Results: The QLQC3O questionnaire is a cancer-specific scale used to establish the quality of life score like many others, but with the difference that it is simpler, easier to use and more widely used. We have recorded 79 cases of mastectomy for breast cancer. The prevalence of mastectomy was 5.8%. The median age was 58 years. Patients had at least one child 92.38%. Non-specific ductal carcinoma was the most common histological type with 87.33%.The side effects of mastectomy affect the area of symptoms were the most difficult stage to bear with p value not significant. These situations have seriously affected self-esteem. Among the side effects affecting quality of life (52 cases), digestive disorders (22 cases) were in the first place, followed by dyspnea (7 cases) and financial difficulties (8 cases) which resulted in the sale of goods. Conclusion: The place of quality of life remains undeniable in the therapeutic strategy and its evaluation improves the therapeutic choice

Comparison of medical image interpretation time between conventional and automated methods of breast ultrasound

Abstract Objective: To compare the medical image interpretation's time between the conventional and automated methods of breast ultrasound in patients with breast lesions. Secondarily, to evaluate the agreement between the two methods and interobservers. Methods: This is a cross-sectional study with prospective data collection. The agreement's degrees were established in relation to the breast lesions's ultrasound descriptors. To determine the accuracy of each method, a biopsy of suspicious lesions was performed, considering the histopathological result as the diagnostic gold standard. Results: We evaluated 27 women. Conventional ultrasound used an average medical time of 10.77 minutes (± 2.55) greater than the average of 7.38 minutes (± 2.06) for automated ultrasound (p<0.001). The degrees of agreement between the methods ranged from 0.75 to 0.95 for researcher 1 and from 0.71 to 0.98 for researcher 2. Among the researchers, the degrees of agreement were between 0.63 and 1 for automated ultrasound and between 0.68 and 1 for conventional ultrasound. The area of the ROC curve for the conventional method was 0.67 (p=0.003) for researcher 1 and 0.72 (p<0.001) for researcher 2. The area of the ROC curve for the automated method was 0. 69 (p=0.001) for researcher 1 and 0.78 (p<0.001) for researcher 2. Conclusion: We observed less time devoted by the physician to automated ultrasound compared to conventional ultrasound, maintaining accuracy. There was substantial or strong to perfect interobserver agreement and substantial or strong to almost perfect agreement between the methods.

Radioterapia previa a la mastectomía para facilitar la reconstrucción mamaria inmediata / Premastectomy Radiation Therapy to Facilitate Immediate Breast Reconstruction

Les explicaré cómo la radiación complica la reconstrucción mamaria, particularmente en pacientes que necesitan una mastectomía. Tradicionalmente solemos administrar la radiación después de nuestra cirugía y, a menudo, en los Estados Unidos, Europa y en otros lugares, cuando sabemos que el paciente va a necesitar radioterapia postmastectomía, no recibirá ninguna reconstrucción. De hecho, en nuestro estudio clínico en el MD Anderson, solo alrededor del 50% de las pacientes recibió su reconstrucción cuando la deseaban, debido a las complicaciones de la radiación. Sabemos que la reconstrucción diferida tiene un gran efecto psicológico inmediato para la paciente que se hace una mastectomía que no está balanceada. Por supuesto que este es un resultado muy lindo, pero hubiera sido muy bueno si hubiéramos podido preservar su simetría y darle una reconstrucción inmediata. Esto lo hizo un colega mío del que verán muchas fotos, Mark Schaverien, que es un cirujano de mama del Reino Unido que vino al MD Anderson para aprender cirugía microvascular, ahora es profesor y participa en todos nuestros estudios clínicos y reconstrucciones

TAILORx, RxPONDER y direcciones futuras para la prueba Oncotype DX Breast Recurrence Score / TAILORx, RxPONDER and Future Directions for the Oncotype DX Breast Recurrence Score Test

Soy oncóloga clínica y como ustedes escucharon, estuve en la Universidad del Sur de California durante 30 años, como directora del Programa de Cáncer de Mama. Pero ahora soy empleada de una empresa que se llama Exact Sciences, que produce Oncotype DX, por eso tengo un conflicto de intereses. Dentro de los múltiples temas que trataré en estos treinta minutos, primero voy a revisar las nuevas actualizaciones sobre el estudio TAILORx, hablaré del estudio RXPONDER y los datos nuevos que provienen de allí y, debido a que el porcentaje de la población judía en Argentina es alto, quisiera hablar de datos que quizás no conozcan con respecto a tener la mutación BRCA1 o BRCA2 germinal y el Oncotype. Quiero hablar de las Guías NCCN y de ASCO para estos clasificadores y también de brechas de la evidencia y hacia dónde vamos con el Oncotype para ayudar a las pacientes con cáncer de mama. Como muchos de ustedes saben y como ya se habló en la última presentación, todos los estudios genómicos disponibles, el Oncotype, el Mammaprint, EndoPredict, son todos para pronóstico. Si uno le da al paciente una terapia endócrina, nos va a ayudar a entender cuál es el riesgo remanente. El único estudio predictivo es el Oncotype DX, en base a múltiples datos

Aspectos Morfológicos de la Mama. Una Revisión de la Literatura / Morphological Aspects of the Breast. A Literature Review

La glándula mamaria tiene su origen embriológico, posteriormente se diferencia histológica y anatómicamente; a lo largo del tiempo se han ido descubriendo nuevos hallazgos, además de nueva terminología. El objetivo de este trabajo consistió en describir la actualización en los aspectos morfológicos de la glándula mamaria. Se realizó una búsqueda de artículos en diferentes fuentes primarias y secundarias de la literatura científica como: Pubmed, Embase, WOS, Scopus, Scielo obteniendo 623 publicaciones, seleccionado 53 para su revisión y 17 incluidos. La mama se ha ido actualizando en los aspectos morfológicos; Los conductos se ubican cercanos a la areola y al pezón donde desembocan directamente, las ramificaciones de los conductos se ubican cercanos a la areola; los pezones tienen entre 15 y 20 lóbulos, de los cuales sólo 5-9 son verdaderos orificios del conducto mamario, no existen senos lactíferos por lo que la leche desemboca directamente en el pezón, en cuanto a la inervación de la mama son inervados por las ramas cutáneas anterior y lateral de los nervios intercostales. La evidencia existente demuestra la necesidad de realizar estudios permanentes en el ámbito de la morfología, como fue descrito en este artículo de revisión sobre la mama. En diferentes aspectos, tales como términos, funciones y estructuras. Está información es importante para, la formación de pregrado, post grado, y su utilización en la clínica, identificación de patologías, clínicas de lactancia, entre otros.

SUMMARY: The mammary gland has its embryological origin, later it differentiates histologically and anatomically; over time new findings have been discovered, as well as new terminology. The aim of this work was to describe the update on the morphological aspects of the mammary gland. A search for articles was carried out in different primary and secondary sources of scientific literature such as: Pubmed, Embase, WOS, Scopus, Scielo, obtaining 623 publications, 53 selected for review and 17 included. The breast has been updated in morphological aspects; the ducts are located close to the areola and the nipple where they open directly, the branches of the ducts are located close to the areola; the nipples have between 15 and 20 lobes, of which only 5- 9 are true mammary duct orifices, there are no lactiferous sinuses, so the milk flows directly into the nipple, in terms of innervation of the breast they are innervated by the anterior and lateral cutaneous branches of the intercostal nerves. The existing evidence demonstrates the need for permanent studies in the field of morphology, as described in this review article on the breast. In different aspects, such as terms, functions and structures. This information is important for undergraduate and postgraduate training, and its use in the clinic, identification of pathologies, lactation clinics, among others.

Mama supranumeraria: resección mediante técnica abierta con dren versus sin dren / Supranumerary breast: resection by open technique with drain vs without drain

Introducción. El tejido mamario accesorio es una anomalía congénita que se presenta en el 2-6 % de la población femenina. En este tejido se pueden desarrollar las mismas patologías que en la mama normal. El manejo curativo es la resección quirúrgica. El objetivo de este estudio fue comparar los resultados de la técnica de resección vía abierta de tejido mamario accesorio con dren vs sin dren. Métodos. Se realizó un estudio observacional tipo cohorte retrospectivo, teniendo en cuenta dos grupos de pacientes con tejido mamario accesorio: a uno de ellos se les realizó resección quirúrgica mediante técnica abierta con dren y al otro grupo sin dren. Además, se incluyó un brazo prospectivo donde se evaluó la calidad de vida y la satisfacción de las pacientes con el resultado posoperatorio mediante el uso de la herramienta Breast-Q. Resultados. Se recolectó la información de 82 pacientes, la mayoría mujeres; 22 se intervinieron con técnica con dren y 60 con técnica sin dren. 13,6 % de los pacientes presentaron complicaciones tempranas, siendo la infección de sitio operatorio la más frecuente (36,4 %). En general, las complicaciones fueron más comunes en el grupo con dren (40,9 % vs 3,4 %), con una diferencia estadísticamente significativa (p=0,000). La calidad de vida fue similar en ambos grupos. Conclusiones. Los pacientes a quienes se les realizó resección de mama supernumeraria y se dejó un sistema de drenaje en el lecho de disección presentaron más complicaciones posoperatorias que las pacientes a quienes no se les dejó dren

Introduction. Accessory breast tissue is a congenital anomaly that occurs in 2-6% of the female population. It can develop the same pathologies that in the normal breast. The curative management of this pathology is surgical resection. The objective of this study was to compare the results of the accessory breast tissue open resection technique with a drain vs without a drain. Methods. An observational retrospective cohort study was conducted considering two groups of patients with accessory breast tissue: one of them underwent surgical resection using an open technique with a drain and the other group without a drain. In addition, a prospective arm where the quality of life and satisfaction of the patients with the postoperative result was evaluated by the Breast-Q tool. Results. Eighty-two patients were included, most of them women; 22 were operated with open technique with drain and 60 without drain. 13.6% of patients presented early complications, with surgical site infection being the most frequent (36.4%) and, in general, complications were more common in the group with drain (40.9% vs 3.4%) with a statistically significant difference (p=0.000). Quality of life was similar in both groups.Conclusions. Patients who undergo supernumerary breast resection and leaving drainage in the dissection bed present more postoperative complications compared to those without drain

Establishment and validation of a multigene model to predict the risk of relapse in hormone receptor-positive early-stage Chinese breast cancer patients / 中华医学杂志(英文版)

BACKGROUND@#Breast cancer patients who are positive for hormone receptor typically exhibit a favorable prognosis. It is controversial whether chemotherapy is necessary for them after surgery. Our study aimed to establish a multigene model to predict the relapse of hormone receptor-positive early-stage Chinese breast cancer after surgery and direct individualized application of chemotherapy in breast cancer patients after surgery.@*METHODS@#In this study, differentially expressed genes (DEGs) were identified between relapse and nonrelapse breast cancer groups based on RNA sequencing. Gene set enrichment analysis (GSEA) was performed to identify potential relapse-relevant pathways. CIBERSORT and Microenvironment Cell Populations-counter algorithms were used to analyze immune infiltration. The least absolute shrinkage and selection operator (LASSO) regression, log-rank tests, and multiple Cox regression were performed to identify prognostic signatures. A predictive model was developed and validated based on Kaplan-Meier analysis, receiver operating characteristic curve (ROC).@*RESULTS@#A total of 234 out of 487 patients were enrolled in this study, and 1588 DEGs were identified between the relapse and nonrelapse groups. GSEA results showed that immune-related pathways were enriched in the nonrelapse group, whereas cell cycle- and metabolism-relevant pathways were enriched in the relapse group. A predictive model was developed using three genes ( CKMT1B , SMR3B , and OR11M1P ) generated from the LASSO regression. The model stratified breast cancer patients into high- and low-risk subgroups with significantly different prognostic statuses, and our model was independent of other clinical factors. Time-dependent ROC showed high predictive performance of the model.@*CONCLUSIONS@#A multigene model was established from RNA-sequencing data to direct risk classification and predict relapse of hormone receptor-positive breast cancer in Chinese patients. Utilization of the model could provide individualized evaluation of chemotherapy after surgery for breast cancer patients.

Development in the last 20 years of anti-HER2 targeted therapy for breast cancer / 中华外科杂志

Since trastuzumab was listed and approved for breast cancer in 2002, China has entered a new epoch of targeted therapy. Over the past 20 years, anti-human epidermal growth factor receptor 2 (HER2) targeted therapy for breast cancer in China has experienced the era of single-target, tyrosine kinase inhibitors, double-target and anti-HER2 plus antibody-drug conjugate. Advancement in the anti-HER2 targeted therapy is continuously changing the treatment mode of patients with HER2 positive status and even HER2 low expression, significantly improved their prognosis. In the past 20 years, Chinese scholars have participated in international clinical researches, completed a series of registration studies of imported drugs, developed new drugs with proprietary intellectual property rights, enriched the evidence of clinical research on HER2-targeted therapy, and formed a treatment system with both international standards and Chinese characteristics. In particular, the formulation of the Chinese Society of Clinical Oncology Breast Cancer Guidelines and the Chinese expert consensus on anti-HER2 targeted treatment in breast cancer are the concentrated embodiments of Chinese wisdom.

Application of volume replacement techniques in breast conserving surgery for breast cancer treatment / 中华外科杂志

Objective: To examine the application of volume replacement techniques in breast conserving surgery for breast cancer. Methods: The clinic data of 76 breast cancer patients underwent a breast conserving surgery with volume replacement techniques at the Breast Center, Beijing Tongren Hospital, from June 2019 to June 2021 were analyzed retrospectively. All patients were female, aged (42.6±6.4) years (range: 32 to 56 years). Tumor staging inlcuded stage ⅡA in 36 cases, stage ⅡB in 24 cases, stage ⅢA in 12 cases, stage ⅢB in 4 cases. Three types of techniques included the lateral thoracic adipofascial flaps in 47 cases, the upper abdominal wall adipofascial flaps in 22 cases and the latissimus dorsi myocutaneous flap in 7 cases. The specimen volume of tumor expansion resection in breast conserving surgery was measured, while the operative time used for volume replacement techniques, postoperative drainage retention time, postoperative complications and patients' satisfaction with the breast shape were recorded. Results: The specimen volume of tumor was (100.9±24.2) ml (range: 55 to 157 ml) in lateral thoracic adipofascial flap group, (88.4±14.5) ml (67 to 118 ml) in upper abdominal wall adipofascial flap group, (179.7±22.9) ml (range: 155 to 220 ml) in latissimus dorsi myocutaneous flap group. The operative time used to restore the breast shape of the three groups were (52.9±9.0) minutes (range: 45 to 70 minutes), (63.2±8.8) minutes (range: 50 to 70 minutes) and (99.3±3.4) minutes (range: 95 to 105 minutes), respectively. The postoperative drainage retention times of the three groups were (8.6±1.2) days (range: 7 to 10 days), (9.4±0.9) days (range: 8 to 10 days) and (11.4±1.3) days (range: 10 to 13 days), respectively. All the 76 patients were evaluated for their satisfaction with the cosmetic outcomes, 64 patients (84.2%) were strongly satisfied and 12 patients (15.8%) were generally satisfied. The postoperative complications included fat liquefaction in 6 cases (2 cases in the lateral thoracic adipofascial flap group and 4 cases in the upper abdominal adipofascial flap group) and seroma in 4 cases (each 2 cases in the lateral thoracic adipofascial flap group and the latissimus dorsi myocutaneous flap group). Conclusions: For patients with large tissue loss during breast conserving surgery, the corresponding volume replacement techniques, including lateral thoracic adipofascial flaps, upper abdominal wall adpofascial flaps and latissimus dorsi myocutaneous flaps, should be reasonably selected for repair according to the tumor site and the size of the intraoperative breast loss, which can ensure the original volume and shape of the breast, with controllable postoperative complications.

Magnetic resonance differential analysis for different hormone receptor expression status in HER-2-positive breast cancer / 中南大学学报(医学版)

OBJECTIVES@#Currently, it is difficult to assess the expression status of hormone receptor (HR) in breast malignant tumors with human epidermal growth factor receptor 2 (HER-2)-positive in the early preoperative stage, and it is difficult to predict whether it is non-invasively. This study aims to explore the value of MRI on the different HR expression status (HR+/HR-) in HER-2 positive breast cancer.@*METHODS@#Thirty patients with HR+ HER-2-positive breast cancer (HR+ group) and 23 patients with HR-HER-2-positive breast cancer (HR- group) from the First Hospital of Hunan University of Traditional Chinese Medicine between January 7, 2015 and November 26, 2021 were selected as subjects, and all the patients were examined by MRI and all were confirmed by surgery or pathological biopsy puncture. The immunohistochemical staining results were used as the gold standard to analyze the basic clinical conditions, peri-lesion conditions and MRI sign characteristics in the 2 groups.@*RESULTS@#There were all significant differences in terms of mass margins, internal reinforcement features, and apparent diffusion coefficient (ADC) values between the HR+ group and the HR- group (all P<0.05). The logistic multivariate regression model showed that: when the lesion presented as a mass-type breast cancer on MRI, the internal enhancement features of the lesion were an independent predictor for differentiation in the 2 types of breast cancer [odds ratio (OR)=5.95, 95% CI: 1.223 to 28.951, P<0.05], and the mass margin (OR=0.386, 95% CI: 0.137 to 1.082, P>0.05) and ADC value (OR=0.234, 95% CI: 0.001 to 105.293, P>0.05) were not the independent predictors in distinguishing the 2 types of breast cancer.@*CONCLUSIONS@#Multiparametric MRI has good diagnostic value for HR expression status in HER-2-positive breast cancer. Combined logistic regression analysis to construct a predictive model may be helpful to the identical diagnosis.

Malignant Phyllodes Tumor in the male: A case report

@#Phyllodes tumors are breast tumors accounting for about 1% of all breast neoplasms in women and are rare in males. Reported here is a case of a 45-year-old male presenting with a rapidly enlarging right breast mass with invasion of the anterior chest wall. Core Needle Biopsy revealed Malignant Phyllodes Tumor. He underwent wide excision and chest wall resection. Reconstruction was performed using polyropelene mesh, a latissimus dorsi flap and split thickness skin grafting. Patient was discharged on the 33rd post-operative day due to delayed expansion of the right lung from splinting and subsequent near-complete loss of the split thickness skin graft over the latissimus muscle flap. On the recommendation of the plastic surgeon, the wound was allowed to heal by secondary intention. This report draws attention to the rarity of malignant phyllodes tumor in males, and the difficulty of recognizing a malignant pathology in males presenting with breast mass. It also highlights a cost-effective treatment option in the management of these tumors.

GMIA-Breast Oncoplastic and Reconstruction Society consensus on operative standards of breast cancer surgery / 南方医科大学学报

The trend of accurate pathology diagnosis of breast cancer / 中华病理学杂志

Accurate pathology diagnosis of breast cancer is the premise of personalized treatment. In recent years, the pathology diagnosis of breast cancer have been updated and optimized to provide better guidance and basis for clinical treatment. In this paper, we provide an overview on the advances in histological classification of breast cancer, the progress of biomarker detection related to novel antibody-drug conjugates and immunotherapy in breast cancer, the pathology evaluation of breast cancer specimen after neoadjuvant therapy and sentinel lymph nodes, the progress of genetic testing in breast cancer, and the application of artificial intelligence in breast pathology.

Sobrepeso e obesidade entre mulheres e associação com características demográficas e obstétricas entre usuárias de uma unidade de saúde especializada / Overweight and obesity between women and association with demographic and obstetric characteristics among users of a specialized health unit

Resumo Introdução O excesso de peso é um fator de risco para doenças crônicas. Objetivo Estimar a prevalência de sobrepeso e obesidade, e investigar sua associação com variáveis demográficas, socioeconômicas e reprodutivas e com comportamentos relacionados à saúde entre mulheres usuárias de unidade de atenção especializada. Método Estudo transversal com mulheres em atendimento por mastologista. O estado nutricional foi classificado por meio do índice de massa corporal. Foram utilizados modelos de regressão logística multinomial brutos e ajustados, com estimativa de razões de chance (RC) e intervalos de confiança de 95% (IC95%). A eutrofia foi considerada como categoria de referência. Resultados Participaram 182 mulheres com média de idade de 51 anos. A prevalência de sobrepeso foi de 34,1% (IC95% 27,1-41,0) e de obesidade foi de 31,8% (IC95% 25,0-38,7). Apresentaram maiores chances de obesidade as mulheres: com 60 anos ou mais, que exerciam atividade remunerada, que tiveram menarca antes dos 13 anos e com três ou mais gestações. Após análise ajustada, permaneceram associadas à maior chance de obesidade a menarca antes dos 13 anos (RC 4,40; IC95% 1,76-10,99) e três ou mais gestações (RC 8,50; IC95% 2,14-33,70). Conclusão Verificou-se elevada prevalência de sobrepeso e obesidade entre as participantes, associada às características reprodutivas.

Abstract Background Overweight is a risk factor for chronic diseases. Objective To estimate the prevalence of overweight and obesity and to investigate its association with demographic, socioeconomic, reproductive and health behaviors related among women users of specialized care units. Method Cross-sectional study with women in care by a mastologist. Nutritional status was classified by Body Mass Index (BMI). Gross and adjusted multinomial logistic regression models were used, to estimate an Odds Ratios (OR) and 95% Confidence Intervals (95% CI). Eutrophy was considered as a reference category. Results 182 women with a mean age of 51 years. The prevalence of overweight was 34.1% (CI 95% 27.1-41.0) and obesity was 31.8% (CI 95% 25.0-38.7). Women were more likely to be obese: 60 years of age or older, who were gainfully employed, who had menarche before age 13, and with three or more pregnancies. After adjusted analysis, they remained associated with a greater chance of the development of obesity to menarche before 13 years (OR 4.40 CI 95% 1.76-10.99) and three or more pregnancies (OR 8.50 CI 95% 2.14-33.70). Conclusion There was a high prevalence of overweight and obesity among the participants, associated with reproductive characteristics.
