          Abstract

          OBJETIVO: Avaliar a ocorrência de síndrome metabólica (SM) em mulheres na pós-menopausa tratadas de câncer de mama. MÉTODOS: Estudo clínico, transversal, com 158 mulheres na pós-menopausa (amenorreia >12 meses e idade ≥45 anos) tratadas de câncer de mama e livres de doença há pelo menos cinco anos. Por meio de entrevista foram coletados dados clínicos e avaliados o índice de massa corpórea (IMC) e a circunferência da cintura (CC). Na análise bioquímica foram solicitadas dosagens de colesterol total (CT), HDL, LDL, triglicerídeos (TG), glicemia, insulina e proteína C-reativa (PCR). Foram consideradas com SM as mulheres que apresentaram três ou mais critérios diagnósticos: CC>88 cm; TG≥150 mg/dL; HDL colesterol <50 mg/dL; pressão arterial≥130/85 mmHg; glicemia de jejum≥100 mg/dL. Para análise estatística foram empregados o teste t de Student e o teste do χ². RESULTADOS: A média de idade das pacientes foi de 63,1±8,6 anos, com tempo médio de seguimento de 9,1±4,0 anos. A SM foi diagnosticada em 48,1% (76/158) e entre os critérios diagnósticos, o mais prevalente foi obesidade abdominal (CC>88 cm) afetando 54,4% (86/158) das mulheres. As pacientes sem SM tiveram maior tempo de seguimento quando comparadas àquelas com SM (p<0,05). Em relação ao IMC atual, aquelas sem SM eram em média sobrepeso e aquelas com SM eram obesas (p<0,05). Entre estas, na comparação entre o IMC no momento do diagnóstico do câncer e o atual foi observado ganho significativo de peso (27,8±5,4 versus 33,4±5,4 kg/m²) (p<0,05). O valor médio de PCR foi superior nas mulheres com SM (p<0.05). Na comparação das características tumorais e tratamentos oncológicos não houve diferença significativa entre as mulheres com e sem SM. CONCLUSÃO: Mulheres na pós-menopausa tratadas de câncer de mama têm elevado risco de desenvolver síndrome metabólica e obesidade central.

          PURPOSE: To assess the occurrence of metabolic syndrome (MetS) in postmenopausal breast cancer survivors. METHODS: A total of 158 breast cancer survivors were included in this cross-sectional study. Eligibility criteria were: women with amenorrhea >12 months and age ≥45 years, treated for breast cancer and no metastasis for at least five years. Clinical history and anthropometric indicator data (body mass index (BMI), and waist circumference, (WC) were collected. Biochemical parameters, including total cholesterol, HDL, LDL, triglycerides (TG), glucose and C-reactive protein (CRP), were measured. MetS was diagnosed as the presence of at least three of the following diagnostic criteria: WC>88 cm, blood pressure≥130/85 mmHg, triglycerides≥150 mg/dl, HDL <50 mg/dL,and glucose≥100 mg/dL. The Student's t-test and χ² test were used for statistical analysis. RESULTS: The mean age of breast cancer survivors was 63.1±8.6 years, with a mean follow-up of 9.1±4.0 years. MetS was diagnosed in 48.1% (76/158) and the most prevalent diagnostic criterion was abdominal obesity (WC>88 cm), affecting 54.4% (86/158) of the women. The patients without MetS had a longer follow-up compared those with MetS (p<0.05). Regarding the current BMI, PN average, those without MetS were overweight, and those with MetS were obese (p<0.05). Among the latter, comparison of BMI at the time of cancer diagnosis and current BMI (27.8±5.4 versus 33.4±5.4 kg/m²) showed a significant weight gain (p<0.05). Mean CRP values were higher in women with MetS (p<0.05). In the comparison of tumor characteristics and cancer treatments there was no difference between groups (p>0.05). CONCLUSION: Postmenopausal breast cancer survivors had a higher risk of developing metabolic syndrome and central obesity.

          Increasing prevalence of the metabolic syndrome among u.s. Adults.

          The prevalence of the metabolic syndrome is high among U.S. adults. Our purpose was to determine whether the prevalence of this syndrome has changed since 1988-1994. A total of 6,436 men and women aged > or = 20 years from the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and 1,677 participants from NHANES 1999-2000 were included in the analyses. We used the definition of the metabolic syndrome developed by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. The unadjusted prevalence of the metabolic syndrome was 23.1% in NHANES III and 26.7% in NHANES 1999-2000 (P = 0.043), and the age-adjusted prevalences were 24.1 and 27.0% (P = 0.088), respectively. The age-adjusted prevalence increased by 23.5% among women (P = 0.021) and 2.2% among men (P = 0.831). Increases in high blood pressure, waist circumference, and hypertriglyceridemia accounted for much of the increase in the prevalence of the metabolic syndrome, particularly among women. The increased prevalence of the metabolic syndrome is likely to lead to future increases in diabetes and cardiovascular disease. Copyright 2004 American Diabetes Association
