Non Electrocardiographic alterations in exercise testing in asymptomatic women. Associations with cardiovascular risk factors

OBJECTIVES: To estimate the prevalence of exercise testing alterations in middle-aged women without symptoms of heart disease and to verify the associations of functional capacity and heart rate behavior during and after exercise with cardiovascular risk factors. METHODS: A cross-sectional study was conducted with 509 asymptomatic women aged between 46 and 65 years who underwent clinical evaluations and exercise testing (Bruce protocol). The heart rate behavior was evaluated by the maximal predicted heart rate achieved, chronotropic index and recovery heart rate. RESULTS: The mean age was 56.4±4.8 years, and 13.4% of the patients had a Framingham risk score above 10%. In the exercise treadmill testing, 58.0% presented one or more of the following alterations (listed in order of ascending prevalence): symptoms (angina, dyspnea, and dizziness), ST-segment depression, arrhythmia, reduction in recovery heart rate of p12 bpm at 1 minute, altered maximal predicted heart rate achieved, abnormal blood pressure, functional capacity deficiency, and altered chronotropic index. In the multivariate analysis, the following associations (odds ratio) were observed for these alterations: chronotropic index was associated with obesity (2.08) and smoking (4.47); maximal predicted heart rate achieved was associated with smoking (6.45); reduction in the recovery heart rate at 1 minute was associated with age (1.09) and obesity (2.78); functional capacity was associated with age (0.92), an overweight status (2.29) and obesity (6.51). CONCLUSIONS: More than half of middle-aged women without cardiovascular symptoms present alterations in one or more exercise testing parameters. Alterations in the functional capacity or heart rate behavior, as verified by exercise testing, are associated with age, smoking, an overweight status and obesity

Modificações da qualidade de vida sexual de obesos submetidos à cirurgia de Fobi-Capella

OBJETIVO: Analisar as modificações na qualidade de vida sexual de obesos, proporcionadas pela redução do peso corpóreo, após a realização da gastroplastia à Fobi-Capella. MÉTODOS: Estudo quantitativo, prospectivo e longitudinal com cortes transversais, realizado entre março de 2005 e março de 2007, com 21 obesos mórbidos. Critérios de inclusão: idade de 20 a 50 anos, índice de massa corpórea (IMC) =40 Kg/m² e insucesso em tentativas de tratamento clínico para obesidade nos últimos dois anos. Coleta de dados clínicos em prontuários e aplicação de questionário específico com questões relativas à função sexual, realizadas antes e seis meses após a cirurgia. Os escores obtidos foram analisados com o auxilio do programa Epi-Info6, empregando o teste T de student para amostras pareadas. RESULTADOS: O valor total aumentou seis meses após a cirurgia em 76,19%, permaneceu inalterado em 14,29% e diminuiu em 9,52%. Os domínios referentes a função erétil e a relação sexual aumentaram em 71,42%, ao desejo sexual em 52,38% e ao orgasmo em 28,57%. A satisfação sexual aumentou em 57,14%. As médias do valor total e dos seus domínios antes e seis meses após a cirurgia, exceto aquelas referentes ao orgasmo e ao desejo sexual, apresentam diferenças estatisticamente significativas. CONCLUSÃO: A qualidade de vida sexual em homens obesos melhora após a realização da gastroplastia à Fobi-Capella. Evidenciaram-se modificações favoráveis na função sexual desses indivíduos após a perda de peso

Carotid Atherosclerosis in Pre- and Post-Menopausal Women with a History of Pregnancy-Induced Hypertension: Case-Control Study

<div><p>Abstract Background: Cardiovascular disease mortality among women remains high. Observational studies are controversial about the participation of a history of gestational hypertensive disorder in cardiovascular risk. Objective: To verify the association between carotid atherosclerosis in menopausal women who had pregnancy-induced hypertension. Methods: Case-control study, with cases consisting of women with carotid atherosclerosis, defined as carotid intima-media thickness > 1 mm and/or presence of carotid plaques; the controls did not have these alterations. The significance level was set at 95%. Results: A total of 504 women without previous cardiovascular disease were assessed, 126 cases and 378 controls. Of the total, 67% were hypertensive; 76% were dyslipidemic; and 16% were diabetic. Approximately 10% reported a history of hypertension during pregnancy. Women with carotid atherosclerosis had higher values of systolic blood pressure (134.18 mmHg vs. 128.59 mmHg, p = 0.008) and LDL-cholesterol (156.52 mg% vs. 139.97 mg%; p = 0.0005). No statistical difference was found regarding the presence of carotid atherosclerosis and history of hypertension during pregnancy (OR 1.672, 95% CI: 0.883-3.131). Conclusion: The history of hypertension during pregnancy was not associated with subclinical carotid atherosclerosis in menopausal women. However, an association was observed between carotid atherosclerosis and classic risk factors, such as elevated systolic blood pressure and LDL-cholesterol levels.</p></div

Reasons and Barriers to Lose Weight: Obese Adolescents' Point of View

Aims: To identify the reasons why obese adolescents seek weight loss therapy and what barriers they face in losing weight. Study Design: Cross-sectional study. Place and Duration of Study: Department of Physical Education and School Medical Science, University of Pernambuco 2009-11. Methodology: The study was conducted with 128 obese adolescents (76 girls [BMI=35.46±3.92] and 52 boys [BMI=33.70±2.88]), aged between 12 to 18 years old. Personal reasons for seeking weight loss treatment and barriers to losing weight were obtained by an individual semi-structured interview (8 questions) conducted by a psychologist. All individual interviews lasted approximately 20 min and were performed in a quiet room. Adolescents’ answers were semi-transcribed by the researcher and the content was anonymously analyzed in order to categorize the data. Results: The main reason for girls to start a weight loss program was to become healthy (39.47%), followed by to fit in clothes (30.26%), personal appearance (30.26%), and bullying (28.95%). Physical fitness (40.38%) was the most important reason to seek weight loss for boys, followed by to become healthy (36.54%), and bullying (25%). For both genders, the main barriers described were lack of self-control (47.37% - 36.54%), lack of social support (27.63% - 30.77%), and self-motivation (22.37% - 21.15%). Conclusion: Obese adolescents had several reasons for seeing weight loss. Overall, becoming healthy was the main motivation for weight loss and lack of self-control was the main barrier. This information can be used to help develop more effective weight loss strategies for obese adolescents
