Dietary factors associated with metabolic syndrome in Brazilian adults

Background: Metabolic Syndrome (MS) is defined as the association of numerous factors that increase cardiovascular risk and diet is one of the main factors related to increase the MS in the population. This study aimed to evaluate the association of diet on the presence of MS in an adult population sample.Methodology: 305 adults were clinically screened to participate in a lifestyle modification program. Anthropometric assessments included waist circumference (WC), body fat and calculated BMI (kg/m(2)) and muscle-mass index (MMI kg/m(2)). Dietary intake was estimated by 24 h dietary recall. Fasting blood was used for biochemical analysis. MS was diagnosed using NCEP-ATPIII (2001) criteria with adaptation for glucose (>= 100 mg/dL). Logistic regression (Odds ratio) was performed in order to determine the odds ratio for developing MS according to dietary intake.Results: An adequate intake of fruits, OR = 0.52 (CI:0.28-0.98), and an intake of more than 8 different items in the diet (variety), OR = 0.31 (CI: 0.12-0.79) showed to be a protective factor against a diagnosis of MS. Saturated fat intake greater than 10% of total caloric value represented a risk for MS diagnosis, OR = 2.0 (1.04-3.84).Conclusion: Regarding the dietary aspect, a risk factor for MS was higher intake of saturated fat, and protective factors were high diet variety and adequate fruit intake.

Metabolic syndrome and its associated risk factors in Brazilian postmenopausal women

Objective To evaluate the prevalence of metabolic syndrome (MetS) and its associated risk factors in Brazilian postmenopausal women.Methods In this cross-sectional study, a total of 368 postmenopausal women, aged 40-75 years, seeking health care at a public outpatient center in Southeastern Brazil, were included. According to the US National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, MetS was diagnosed in subjects with three or more of the following: waist circumference >= 88 cm, blood pressure >= 130/85 mHg, triglycerides >= 150 mg/dl, high density lipoprotein cholesterol <50 mg/dl and glucose >= 110 mg/dl. Data on past medical history, tobacco use, anthropometric indicators, and values of C-reactive protein (CRP) were collected. Multivariate analysis, using a logistic regression model (odds ratio, OR) was used to evaluate the influence of various simultaneous MetS risk factors.Results The prevalence of having at least three, four and five MetS diagnostic criteria were met in 39.6%, 16.8% and 3.8% of the cases, respectively. The most prevalent risk factor was abdominal obesity, affecting 62.5% of women. The risk of MetS increased with a personal history of diabetes (OR 5.95, 95% confidence interval (CI) 2.82-12.54), hypertension (OR 4.52, 95% CI 2.89-7.08), cardiovascular disease (OR 2.16, 95% CI 1.18-3.94) and high CRP (>1 mg/dl) (OR 3.35, 95% CI 1.65-6.79). Plasma CRP levels increased with the number of MetS components present. Age, time since menopause and smoking had no influence, while hormone therapy reduced MetS risk (OR 0.64, 95% CI 0.42-0.97).Conclusion Metabolic syndrome was highly prevalent among Brazilian postmenopausal women seeking gynecologic health care. Abdominal obesity, diabetes, hypertension and high CRP were strong MetS predictors and hormone therapy appeared to play a protective role for this condition.

Climatologia de frentes frias no litoral de Santa Catarina

Uma climatologia de frentes frias é estabelecida para o litoral do Estado de Santa Catarina, com base nos dados de reanálises do NCEP-NCAR, do período de 10 anos, de 1990 a 1999. As passagens de frentes frias foram objetivamente identificadas levando em conta o giro do vento para direção sul, persistência do vento de sul por pelo menos um dia, e uma queda de temperatura do ar simultânea ao giro do vento ou até dois dias depois. Os resultados mostram que, na média, de 3 a 4 frentes frias atingem a costa de Santa Catarina, mensalmente, com um intervalo de 8 dias. As análises da composição de dados, usando como referência os dias de passagens de frentes frias em Santa Catarina, mostram claramente um padrão climatológico de evolução com frente fria movendo-se tipicamente de sudoeste para nordeste. em termos das médias sazonais, durante o inverno, um dia antes da passagem em Santa Catarina (dia -1), a frente fria é observada no Rio Grande do Sul, e depois de passar por Santa Catarina (dia 0), continua avançando para latitudes mais baixas, alcançando o litoral do Rio de Janeiro um dia depois (dia +1), até atingir posteriormente latitude de aproximadamente 20ºS (dia +2), já em fase de dissipação. No terceiro dia após a passagem por Santa Catarina, ela não é mais identificada. Padrão climatológico de evolução semelhante é observado no verão, embora nessa época as frentes frias tenham menor intensidade e dissipação ligeiramente mais rápida.

Consumo de frutas, verduras e legumes associado à Síndrome Metabólica e seus componentes em amostra populacional adulta

A síndrome metabólica (SM) aumenta o risco de eventos cardiovasculares e o consumo adequado de frutas, verduras e legumes (FVL) está relacionado a sua prevenção. Objetivo: Identificar o consumo de FVL e sua relação com a SM e seus componentes em amostra populacional adulta. Estudo prospectivo de corte transversal com 636 indivíduos adultos, no período de 2004 a 2008. Foram realizadas avaliações antropométrica, clínica, dietética e bioquímica com todos participantes. A SM foi classificada pelo NCEP ATP-III, modificada para a glicose >100mg/dl. A regressão logística foi utilizada para verificar a razão de chance entre o consumo de FVL com a SM e seus componentes, e o nível de significância adotado foi de 5%. O consumo de frutas adequado se mostrou protetor para obesidade abdominal (OR: 0,77; IC: 0,38-0,93), hipertrigliceridemia (OR: 0,76; IC: 0,35-0,96) e presença de SM (OR: 0,78; IC: 0,39-0,96), e o consumo adequado de FVL apresentou efeito protetor para a presença de SM (OR: 0,79; IC: 0,41-0,95). A análise isolada do consumo adequado de verduras e legumes não mostrou efeitos de proteção/risco para a presença de SM e de seus componentes. O consumo adequado de FVL apresentou efeito protetor para a presença de SM e o consumo adequado de frutas exerceu efeito protetor tanto para a presença de SM e como de seus componentes.

Eficácia e segurança da atorvastatina no tratamento de pacientes com hipercolesterolemia primária

Introduction: Hypercholesterolemia is an important risk factor for cardiovascular disease, the first cause of death and third reason for hospital admissions in Brazil. The reduction of serum cholesterol levels reduces morbidity and mortality from cardiovascular disease. The present study evaluated the efficacy and safety of atorvastatin in the treatment of Brazilian patients with primary hypercholesterolemia (types IIA and IIB dyslipidemias). Patients and methods: After a 4-week wash-out period, 152 patients were treated with atorvastatin at the initial dose of 10 mg/day. According to treatment efficacy within the first 8 weeks this dose could be increased to 20 mg/day. Treatment lasted for a total of 16 weeks, and its efficacy was evaluated by the reduction of serum levels of LDL-cholesterol, total cholesterol, HDL-cholesterol, and triglycerides, as well as by the propotion of patients that achieved the target levels recommended by the National Cholesterol Education Program - Adult Treatment Panel II (NCEP ATP II) Results: The analysis of efficacy was conducted in 145 patients. Atorvastatin led to significant reductions in the levels of LDL-cholesterol after 8 and 16 weeks of treatment (P<0.001 for both comparisons). The relative reduction of such levels was 38% (P<0.001 after 8 and 16 weeks). Atorvastatin also led to significant reductions of total cholesterol and triglycerides. At the end of the study, 81% of patients achieved the target LDL-cholesterol levels recommended by NCEP ATP II. Treatment was well tolerated, and was interrupted due to creatine phosphokinase elevation in only one patient. Conclusion: Atorvastatina is efficacious and safe in the treatment of patients with primary hypercholesteromia. © Copyright Moreira Jr. Editora. Todos os direitos reservados.

Spurious shifts in the pattern of diurnal variation of sea level pressure of reanalysis datasets

The main purpose of this work is to report the presence of spurious discontinuities in the pattern of diurnal variation of sea level pressure of the three reanalysis datasets from: the National Centers for Environmental Prediction (NCEP) and National Center for Atmospheric Science (R1), the NCEP and Department of Energy (R2), and the European Centre for Medium Range Weather Forecasting (ERA-40). Such discontinuities can be connected to the major changes in the global observing system that have occurred throughout reanalyses years. In the R1, the richest period in discontinuities is 1956-1958, coinciding with the start of modern radiosonde observation network. Rapid increase in the density of surface-based observations from 1967 also had an important impact on both R1 and ERA-40, with larger impact on R1. The reanalyses show discontinuities in the 1970s related to the assimilation of radiances measured by the Vertical Temperature Profile Radiometer and TIROS-N Operational Vertical Sounders onboard satellites. In the ERA-40, which additionally assimilated Special Sensor Microwave/Imager data, there are discontinuities in 1987-1989. The R1 also presents further discontinuities, in 1988-1993 likely connected to replacement/introduction of NOAA-series satellites with different biases, and to the volcanic eruption of Mount Pinatubo in June 1991, which is known to have severely affected measurements of infrared radiances for several years. The discontinuities in 1996-1998 might be partially connected to change in the type of radiosonde, from VIZ-B to VIZ-B2. The R2, which covers only satellite era (1979-on), shows discontinuities mainly in 1992, 1996-1997, and 2001. The discontinuities in 1992 and 2001 might have been caused by change in the satellite measurements and those in 1996-1997 by some changes in land-based observations network. © 2012 Springer-Verlag.
