Red but not white meat consumption is associated with metabolic syndrome, insulin resistance and lipid peroxidation in Brazilian middle-aged men

Background The influence of diet on metabolic syndrome and oxidative stress are not completely known. Design This cross-sectional study assessed the association of red meat and white meat consumption with metabolic syndrome, insulin resistance and lipid peroxidation in Brazilian middle-aged men. Methods A total of 296 subjects (age: 50.5 ± 5.0 years, body mass index: 25.8 ± 3.5 kg/m2) were evaluated. Anthropometry, lifestyle features, blood biochemical parameters, diagnosis of metabolic syndrome, homeostatic model assessment for insulin resistance, a lipid peroxidation marker (oxidized low-density lipoprotein) and triglycerides:high-density lipoprotein cholesterol ratio were assessed. Dietary intake was estimated by a food frequency questionnaire. Results The subjects included in the highest tertile red meat (≥81.5 g/d) and saturated fatty acid from red meat consumption (≥4.3 g/d) had higher occurrence of central obesity (nearly 60%, p < 0.01), hypertriglyceridaemia (nearly 43%, p < 0.01) and metabolic syndrome (35%, p < 0.01). They also had higher values of homeostatic model assessment for insulin resistance, oxidized low-density lipoprotein, and triglycerides:high-density lipoprotein cholesterol ratio, regardless of interfering factors. There were no associations of highest white meat tertile (≥39.4 g/d) and saturated fatty acid from white meat (≥1.0 g/d) consumption with the assessed parameters (p > 0.05). Conclusions Red meat consumption was cross-sectionally associated with the occurrence of central obesity, hypertriglyceridaemia, and metabolic syndrome as well as with higher homeostatic model assessment for insulin resistance, oxidized low-density lipoprotein concentrations and triglycerides:high-density lipoprotein cholesterol ratio. The content of saturated fatty acid from red meat consumption may be a factor that contributed to this relationship, while white meat consumption was not associated with metabolic syndrome and the assessed biomarkers.

Factors associated with insufficient physical activity: a population-based study in southern Brazil

The aim of this study was to estimate the prevalence of insufficient physical activity and to find the factors associated to this outcome in Lages, Santa Catarina, Brazil (2007). A cross-sectional population-based study was carried out in a representative sample of individuals between 20 and 59 years of age (n=2,051). Physical activity was estimated using the short version of the International Physical Activity Questionnaire. Insufficient physical activity was defined as less than 150 minutes per week spent in moderate or vigorous physical activity. The prevalence of insufficient physical activity was 29.6% (95%CI: 27.6; 31.7). The associated factors were to be male, obese, have high income, and negative self-perception of health status. The prevalence of insufficient physical activity was lower than reported by other Brazilian studies. Studies that distinguish different types of physical activity can contribute to a better understanding of the problem. The implementation of public policies that encourage the practice of regular exercises is required.

Prevalência de níveis pressóricos elevados e fatores associados em adultos de Lages/SC

BACKGROUND: Few population-based studies have been carried out in Brazilian medium-sized cities in order to estimate high levels of blood pressure and associated factors. OBJECTIVE: To estimate the prevalence of high blood pressure and associated factors among adults in Lages,Southern Brazil. METHODS: Population-based cross sectional study carried out in adults aged 20 to 59 years living in the urban area (n=2,022). The dependent variable was high levels of blood pressure (> 140/90 mmHg). Exploratory variables: sex, age, schooling, per capita family income, self-reported ethnicity, body mass index, tobacco and alcohol addiction, physical activity and self-reported diabetes. The Chi-square test and linear trends were used to test associations between the dependent variable and the exploratory variables. Unadjusted and adjusted multivariate Poisson regression analyses were performed. RESULTS: Response rate was 98.6%. The prevalence of high blood pressure levels was 33.7% (95CI%: 31.7-36.1) for the population as a whole, ranging from 31.1% in men to 38.1% in women. After statistical adjustment for possible confounders, the following were associated with high blood pressure levels: male gender (PR =1.22 95%CI 1.1-1.4), older age, overweight (PR= 1.40 95%CI 1.18-1.67), obesity (PR = 1.95 95% CI 1.61-2.36), Asian ethnicity (PR 1.29 95%CI 1.12-1.48) and self-reported diabetes mellitus (PR 1.29 95%CI 1.12-1.48). CONCLUSIONS: One third of the assessed adults presented high blood pressure levels, similar to most of the Brazilian findings. Factors that can be prevented, such as overweight, obesity and self-reported diabetes were associated with high blood pressure levels.BACKGROUND Few population-based studies have been carried out in Brazilian medium-sized cities in order to estimate high levels of blood pressure and associated factors.

Preventive programs and qualitative studies could be effective strategies to shed further light on intimate partner violence.

Comparison of functional autonomy with associated sociodemographic factors, lifestyle, chronic diseases (CD) and neuropsychiatric factors in elderly patients with or without the metabolic syndrome (MS)

OBJETIVO: Estimar a prevalencia de tabagismo e fatores associados em adultos com idade entre 20 e 59 anos. METODOS: Estudo transversal de base populacional conduzido em uma amostra de 2.022 individuos residentes na zona urbana de uma cidade de medio porte do sul do Brasil. Realizaram-se entrevistas domiciliares e foram coletadas informacoes sobre aspectos socioeconomicos, demograficos, condicoes auto-referidas de saude, uso de servico medico e odontologico, auto-avaliacao de saude, problemas com alcool, estado nutricional e niveis pressoricos. Consideraram-se fumantes os que relataram consumir nos ultimos trinta dias qualquer quantidade de fumo. Nas analises bivariadas e multivariada calcularam-se as razoes de prevalencias (RP) por meio da regressao de Poisson. RESULTADOS: A prevalencia global de tabagismo foi de 30,1% (IC 95%: 27,8; 32,3). As variaveis associadas a maior prevalencia de tabagismo na analise multivariada foram: renda mais baixa (RP = 1,49; IC 95%: 1,26; 1,77), escolaridade menor que oito anos (RP = 2,07; IC 95%: 1,68; 2,56), relatar problemas com alcool (RP = 1,42; IC 95%: 1,17; 1,73), nao utilizar o servico medico no ultimo ano (RP = 1,21; IC 95%: 1,04; 1,41) e auto-avaliar a saude bucal de forma negativa (RP = 1,28; IC 95%: 1,09; 1,50). Condicoes auto-referidas de saude associadas ao tabagismo foram: catarro (RP = 2,07; IC 95%: 1,83; 2,35), chiado no peito (RP = 1,45, IC 95%: 1,20; 1,75), falta de ar (RP = 1,41 IC 95%: 1,19; 1,66) e a eutrofia (RP = 1,57, IC 95%: 1,36; 1,80). CONCLUSAO: A prevalencia de tabagismo na populacao foi elevada. Politicas publicas sao necessarias para diminuir a prevalencia e morbidade do tabagismo considerando-se a desigual distribuicao dos eventos entre os estratos populacionais.

Benefits and relationship of steps walked per day to cardiometabolic risk factor in Brazilian middle-aged men

The objective of this study was to compare autonomy and its associated factors in the elderly with and without MS. This study was a cross-sectional evaluation comprised of 402 subjects aged 60 years or older, of both sexes, consulting at the Family Health program, in Viçosa/MG. Autonomy was classified according to the Group of Latin American Development to Maturity (GDLAM) protocol and MS according to classification of the International Diabetes Federation. The independent variables were sociodemographic gender, age, marital status, education, those related to lifestyle including levels of physical activity and sedentary behavior, neuropsychological aspects included depressive symptoms, level of cognition and the presence of CD. A multiple linear regression model was used to estimate associations of variables with autonomy in the elderly with or without the MS. In the elderly group without MS, autonomy was associated with increasing age, sedentary behavior and depressive symptoms. In the group of elderly patients with MS, in addition to these factors, autonomy was also associated with being illiterate, not being physically active and presenting chronic illness. It was concluded that the presence of MS worsened the functional autonomy of elderly persons.

Prevalence and distribution of risk factors for non-communicable chronic diseases among adults from Lages city, south of Brazil, 2007.

OBJECTIVES We evaluated the benefits and relationship of the number of steps per day to the cardiometabolic risk factors: adiposity indicators; insulin resistance; and metabolic syndrome (MetS) in apparently healthy Brazilian middle-aged men. DESIGN Cross-sectional. METHODS Apparently healthy men (age: 50 ± 5 years; n=299) were studied. The number of steps per day was measured by pedometer. The adiposity indicators (waist circumference, total body fat, android and gynoid body fat), serum insulin, glucose and triglycerides, triglycerides/high-density lipoprotein cholesterol (HDL-c) ratio, homeostasis model assessment of insulin resistance (HOMA-IR) and MetS were assessed. Subjects were placed in groups to reflect different levels of steps per day (average of 7 consecutive days): Group 1<10,000 and Group 2 ≥ 10,000. Relationships among variables were measured by multiple linear regressions and the Spearman correlation coefficient as appropriate (p<0.05). RESULTS The cardiometabolic risk factors were lower (p<0.05) in Group 2 than in Group 1. The number of steps per day was a negative predictive factor for total body fat, android and gynoid body fat and HOMA-IR independent of age, working position, android fat, overweight/obesity prevalence, and triglycerides/HDL-c ratio. Moreover, there was a negative correlation between the number of steps and total body fat, android and gynoid body fat, HOMA-IR and MetS. CONCLUSIONS Brazilian middle-aged men performing more than 10,000 steps per day have better cardiometabolic conditions than those walking fewer than 10,000 steps. The number of steps per day is inversely related to the indicators of total and regional adiposity, insulin resistance and MetS.

Sepse tardia em pré-termos de uma unidade de terapia intensiva neonatal: análise de três anos

OBJECTIVE To describe prevalence and the distribution of risk factors to non-communicable chronic diseases among adults from Lages, Santa Catarina, Brazil. METHODS Probabilistic sample of adult urban population, of both genders and aged from 20 to 59 years old was interviewed (n=2022). The sample process was made through conglomerates. It was applied a structured questionnaire with questions related to demographical, socio-economical, and behavior and self-referred diseases. In this study the following informations, related to the risk/protection factors for non-communicable chronic diseases, were used: gender, age, school background, body mass index, waist circumference, smoking, physical activity, pressure levels, self-referred mellitus diabetes and feeding characteristics. Prevalence for risk/protection factors for non-communicable chronic diseases, in the total population and according to gender and school background, was calculated. RESULTS The studied population is prone to non-communicable chronic diseases, presenting substantial proportions of hypertension (33.78%), overweight individuals (33.46%), obesity (23.46%) and abdominal obesity (43.81%). In relation to feeding characteristics, women presented higher prevalence of behaviors considered as protection factors, relative to men. It was found less than 30.0% of physically inactive individuals and 45.9% of smokers or ex-smokers. CONCLUSION Descriptive studies such as this could be the basis for the development of public policies specific to the adult population of Lages, in order to guide the organization, planning and quality improvement of health assistance services, aiming the reduction in the occurrence and in the impact of non-communicable chronic diseases.
