Abstract
Postmenopausal women represent an important target population in need of preventative cardiometabolic approaches. The loss of estrogen following the menopause eliminates protections against metabolic dysfunction, largely due to its role in the health and function of adipose tissue. In addition, some studies associate the menopause with reduced physical activity, which could potentially exacerbate the deleterious cardiometabolic risk profile accompanying the menopause. Meanwhile, exercise has adipocyte-specific effects that may alleviate the adverse impact of estrogen loss through the menopausal transition period and beyond. Exercise thus remains the best therapeutic agent available to mitigate menopause-associated metabolic dysfunction and represents a vital behavioral strategy to prevent and alleviate health decline in this population.

Abstract
Objective The aim of this study was to estimate the prevalence of insulin resistance (IR) in a rural population in Brazil, to verify its association with sociodemographic, labor, lifestyle, and health factors. Subjects and methods This is a cross-sectional study with 790 farmers in the state of Espírito Santo/Brazil. Triglyceride-glucose (TyG) was calculated and a cut-off point of Ln 4.52 was used. A hierarchical logistic regression for the association of insulin resistance with sociodemographic, labor, lifestyle and health variables of farmers living in Espírito Santo was performed. Results The prevalence of insulin resistance was 33.7% (n = 266), and the association with insulin resistance was found in the age group 31 to 40 years of age (OR = 1.85; 95% CI 1.19-2.87); in smokers or former smokers (OR = 1.63; 95% CI 1.08-2.48) and overweight (OR = 3.06; 95% CI 2.22-4.23). Conclusion The prevalence of insulin resistance was high in a rural population of Brazil, and was mainly associated with age, smoking and obesity. The use of TyG as an instrument for assessing the health of individuals living in areas where access to health services is difficult, such as rural areas, can represent an important advance in terms of health promotion, protection and recovery. In addition, by identifying the risk factors associated with IR, as well as their consequences, a more adequate scheme for the prevention and treatment of these comorbidities can be defined.

Abstract
The objectives of this study were to assess the nutritional status of rural workers from a municipality in Southeastern Brazil and estimate the association of sociodemographic, labor, lifestyle, and dietary pattern factors with obesity and abdominal obesity of men and women of this rural area. This is a cross-sectional, epidemiological study of 740 farmers (51.5%, n = 381 males; 48.5%, n = 359 females). The sociodemographic, labor, lifestyle and dietary patterns determinants were assessed. Food intake data were obtained by applying three 24-hour recalls and dietary patterns were determined by Principal Component Analysis with Varimax orthogonal rotation. Poisson regression with robust variance stratified by sex was applied. The general prevalence of overweight status was 31.5% (95% CI 28.2-34.8%), 19.7% of obesity (95% CI 16.8-22.6%) and 31.5% of abdominal obesity (95% CI 28.2-34.8%), with higher rates in women (P < 0.001). Men of higher socioeconomic class had a 2.3 times higher prevalence of obesity (95% CI 1.08-4.90). In addition, the shorter travel time to purchase food increased the prevalence of abdominal obesity in males. For women, the older the age group, the greater the general and central obesity. A lower adherence to traditional dietary patterns (approximately PR [prevalence ratio] 1.6 for general obesity and PR 1.3 for abdominal obesity) and a greater number of places to buy food were associated with higher rates of obesity in women. Finally, women farmers with a higher workload had a 20% lower prevalence of central obesity (PR 0.80; 95% CI 0.65-0.97). Such findings demonstrate that obesity must be an issue in the health care of remote and rural populations. There is a need to promote healthier environments that respect traditional food culture through multiple approaches that consider the heterogeneity of rural areas and the differences between sexes.

Abstract
OBJECTIVE Thus, the aim of this study was to identify the cutoff point of the TyG index for the diagnosis of insulin resistance (IR), according to two different diagnostic criteria of metabolic syndrome in a rural Brazilian population. METHODS The study population consisted of 790 family farmers from 18 to 59 years old. The triglyceride-glucose index (TyG index) was calculated, and the Metabolic Syndrome was defined using the NCEP-ATPIII and IDF criteria. Mann-Whitney U test was used to analyze the association of quantitative and qualitative variables. When the qualitative variable had three or more categories, the comparison between the means was performed by the Kruskal-Wallis test (using the Mann-Whitney U Test two by two to identify the differences). For correlations, Spearman's correlation test was used. The cutoff values of TyG index for MetS were obtained using the Receiver Operating Characteristic (ROC) curve analysis with the area under the curve (AUC) and the Youden Index. RESULTS The median TyG values increased according to the aggregation of the components of MetS. The AUCs and Youden's cutoff point for TyG index according to the NCEP and IDF diagnostic criteria were 0.873, Ln 4.52 (sensitivity: 84.30%; specificity: 75.75%), and 0.867, Ln 4.55 (sensitivity: 80.0%; specificity: 79.82%), respectively. CONCLUSION A cutoff point of Ln 4.52 was defined, and it can be used both in clinical practice and epidemiological studies. It represents an important tool for promotion, protection and recovery health of rural populations.

Abstract
We determined the prevalence of Metabolic Syndrome (MetS) and associated factors in 419 women (aged 40 to 65 years) in Northeast Brazil in a cross-sectional study conducted from April to November 2013. We defined MetS using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Socio-demographic variables, reproductive factors, lifestyle factors, anthropometrics, body composition, quality of life, and physical performance were assessed for their associations. We constructed multivariate Poisson regression models to estimate prevalence rate ratios (PRR) and 95% confidence intervals (CI). We identified 275 (65.6%) cases of MetS. The three most prevalent indicators were obesity (73.5%), reduced high-density lipoprotein level (63.0%), and elevated blood pressure (60.9%). In the final adjusted model, black race (PR 1.30, 95% CI: 1.07-1.57), lower grip strength/body mass index (PR 1.31, 95% CI: 1.15-1.50), and low estradiol levels (PR 1.17, 95% CI: 1.00-1.35) were associated with MetS. MetS is a long-term threat to the health of middle-aged women and a potential public health burden. These results may help in developing health promotion strategies to prevent morbidity and mortality associated with MetS in this vulnerable population.

Abstract
This study was aimed to investigate the patterns and possible differences in the levels of Physical Activity (PA) among members of different generations in a North Indian State. A cross-sectional survey investigated intergenerational PA level up to third generations of Jat males and females ( N = 329; 42 families). PA was quantified using the validated Global Physical Activity Questionnaire. Significant differences were observed with respect to the various domains of the PA among generations. Females of the second generation were more active than males, whereas females of the third generation were less active and their activities are confined to household chores only. No such sex-wise differences were observed among first generation. Only 20% of the individuals were performing recreational activities, and almost negligible in the first and second generation. Study supports the need for increasing awareness regarding health benefits of PA especially in terms of recreational activities.

Abstract
Purpose
Older adults are at risk for developing metabolic syndrome (MSX). Given the growing rural older adult population and the unknown prevalence rate of MSX in rural communities, the purpose of this paper is to assess the risk factors for MSX among rural elders.
Design/methodology/approach
Individuals aged 55+ from four West Alabama rural communities were assessed by an interdisciplinary healthcare team via a mobile unit (n=216). Descriptive analyses and analysis of variances (ANOVA) were conducted to assess the effect of gender, race and community on the number of risk factors of MSX among rural elders.
Findings
Results of a three-way ANOVA revealed a significant interaction between gender, age and community on the number of MSX risk factors [F (16,193)= 2.41, p <0.01]. Rural communities with lower social economic status (SES) and predominantly African American residents were at higher risk for developing MSX compared to communities with higher SES [F(3, 68) = 7.42, p<0.05].
Practical implications
Findings suggest low SES rural communities are at risk of developing MSX. Innovative approaches such as mobile healthcare delivery are crucial to providing quality healthcare and preventive health screens to underserved rural older adult communities.
Originality/value
Limited research is available on assessing rural midlife and older adults at risk for metabolic syndrome largely due to lack of communication or transportation infrastructure and their history of negative experiences with public institutions. This research demonstrates that these barriers can be addressed.

Abstract
BACKGROUND The prevalence of low vitamin D status and metabolic syndrome is increasing globally and in Lebanon. The objectives of this study are to assess the prevalence of metabolic syndrome (MetS) and its components (elevated triglycerides, low HDL, abdominal obesity defined by high waist circumference, hypertension, impaired fasting blood glucose) and investigate the association between serum 25-hydroxyvitamin D (25(OH)D) concentrations and MetS and its components among a sample of Lebanese adults. METHODS A cross-sectional study was carried out on Notre Dame University employees. A background questionnaire, a short-form of the International Physical Activity Questionnaire and a food frequency questionnaire were administered. Participants were invited to the nutrition laboratory to gather data on anthropometric (height, waist circumference, weight, body composition and body mass index) and biochemical measurements (serum vitamin D, triglycerides, HDL and fasting blood glucose). Vitamin D status was assessed according to the Institute of Medicine cut-offs (inadequate or adequate: 25(OH)D < or ≥ 50 nmol/L).The definition of the Third Report of the National Cholesterol Education Program was used to identify individuals who had MetS. The data were analyzed using the SPSS version 22. P < 0.05 was considered statistically significant. RESULTS A total of 344 participants (age range of 20 to 74 years) were included in the study. The prevalence of MetS was 23.5%. Among MetS components, central obesity was the most prevalent condition (50.6%), while the least prevalent was impaired fasting blood glucose (20.3%). The odds of having MetS were found to be 2.5 (95% CI 1.3-4.7) higher among those with inadequate vitamin D status, than among those with adequate vitamin D status while controlling for important confounders (age, marital status, education level, income, medical morbidity, smoking and percent body fat and gender). Among the components of MetS, only hypertriglyceridemia (OR: 2.4, 95%CI: 1.3-4.2) and low HDL (OR: 1.8, 95% CI: 1.0-3.0) were associated with inadequate vitamin D status while controlling for important confounders. CONCLUSIONS Early identification and control of risk factors for cardiovascular diseases in the primary care level is needed, particularly among adults who have low vitamin D status, are obese, and have low income level.

Abstract
Este estudo qualitativo, do tipo exploratório, descritivo e bibliográfico, trata-se de uma revisão sistemática da literatura sobre o trabalho da mulher no meio rural, publicado em artigos científicos no Brasil no período de 2006 a 2016 na base de dados BVS-Psi, objetivando descrever o que estas produções exploram em relação a estas mulheres. Utilizaram-se os termos de busca “trabalhadoras rurais” e “mulheres rurais”, sendo a análise dos dados por conteúdo (Bardin, 2011). Os principais achados destacam que a participação das mulheres rurais nas manifestações sociais potencializaram as suas conquistas, bem como evidenciam as preocupações referentes à saúde da trabalhadora rural, em que os/as pesquisadores/as relatam as consequências psíquicas e físicas resultantes da intensificação do trabalho rural paralelo ao doméstico. Conclui-se que somente desde 2013 o número de publicações acerca do tema tem aumentado, sendo os/as pesquisadores da região Sul do Brasil os/as que mais publicam a temática, que foi pesquisada em somente nove das 27 unidades federativas do País, o que aponta para uma invisibilidade das mulheres trabalhadoras rurais nas pesquisas publicadas nesta base de dados, neste período.

Abstract
BACKGROUND Metabolic syndrome (MetS) is an aggregation of risk factors associated with increased incidence of cardiovascular disease, type 2 diabetes mellitus, and all-cause mortality. Information on MetS prevalence is scarce in the northeast region, Brazil. This study aims to estimate the prevalence of MetS according to different diagnostic criteria in a community sample of men during the November Blue Campaign living in the metropolitan area of Natal, Rio Grande do Norte, Brazil. METHODS This is a cross-sectional study on 500 men aged 40 years or older invited by the Blue November Campaign of 2015, an awareness program aimed at the prevention of male diseases. The evaluation included blood pressure, anthropometric measurements (weight, height, and waist circumference), fasting blood glucose, and blood lipid profile. The diagnosis of MetS was made according to the criteria of International Diabetes Federation (IDF)/American Heart Association (AHA)/National Heart, Lung, and Blood Institute (NHLBI), IDF, and National Cholesterol Education Program's Adult Treatment Panel III (NCEP-ATPIII). RESULTS The prevalence was high by considering the following three criteria: IDF/AHA/NHLBI (66.8%), IDF (60.0%), and NCEP-ATPIII (46.4%). Concordance between diagnostic criteria measured by the kappa statistic (k) was excellent between IDF/AHA/NHLBI and IDF (k=0.85, P<0.0001) and moderate between IDF/AHA/NHLBI and NCEP-ATPIII (k=0.59) and IDF and NCEP-ATPIII (k=0.54). CONCLUSION Prevalence of MetS in the male population was high using the three diagnostic criteria. IDF/AHA/NHLBI and IDF criteria have a high level of agreement, but NCEP-ATPIII criteria identify a lower number of MetS cases.

Abstract
The aim of the present study was to investigate levels of physical activity and risk factors for inactivity in older adults living in an urban area in the interior of the Amazonas state, Brazil. Data were collected between 2013 and 2015 from 274 individuals 60 years of age or older who resided in the interior of the Brazilian Amazon. Sociodemographic, general health, functional capacity and physical performance were associated with self-referred physical activity level. A multivariate analysis, after adjustment, showed that being a man, having a body mass index above 27kg/m2, never having lived in riverside communities and having less than three associated chronic diseases were independent risk factors for low levels of physical activity among elderly residing in the interior of the Brazilian Amazon. Few studies have been conducted about the characteristics that are singular to this population. Our results suggest that the physical activity level and, consequently, the aging process of the elderly is influenced by where they have resided throughout their lives. Additionally, the results showed particular risk factors associated with low physical activity level among older adults residing in the interior of the state of Amazonas.

Abstract
Background The metabolic syndrome (MS) is a complex of risk factors for cardiovascular disease. This syndrome increases the risk of diabetes, cardiovascular disease and all-cause mortality. It has been demonstrated that the prevalence of MS is increasing worldwide. Despite the importance of MS in the context of metabolic and cardiovascular disease, few studies have described the prevalence of MS and its determinants in Latin America. The present study aims to assess studies describing the prevalence of MS in Brazil in order to determine the global prevalence of the syndrome and its components. Methods Systematic review. Searches were carried out in PubMed and Scielo from the earliest available online indexing year through May 2013. There were no restrictions on language. The search terms used to describe MS were taken from the PubMed (MeSH) dictionary: “metabolic syndrome x”, “prevalence” and “Brazil”. Studies were included if they were cross-sectional, described the prevalence of MS and were conducted in apparently healthy subjects, from the general population, 19-64 years old (adult and middle aged) of both genders. The titles and abstracts of all the articles identified were screened for eligibility. Results Ten cross-sectional studies were selected. The weighted mean for general prevalence of MS in Brazil was 29.6% (range: 14.9%-65.3%). Half of the studies used the criteria for clinical diagnosis of MS proposed by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) (2001). The highest prevalence of MS (65.3%) was found in a study conducted in an indigenous population, whereas the lowest prevalence of MS (14.9%) was reported in a rural area. The most frequent MS components were low HDL-cholesterol (59.3%) and hypertension (52.5%). Conclusions Despite methodological differences among the studies selected, our findings suggested a high prevalence of MS in the Brazilian adult population.

Abstract
OBJETIVO: Investigar a associação entre índice glicêmico (IG) e/ou carga glicêmica (CG) da dieta e síndrome metabólica (SM). MÉTODOS: Trata-se de estudo documental e do tipo caso-controle, com uma amostra de 229 idosos. Calcularam-se o IG e a CG, classificando-os em adequado (baixo) e inadequado (moderado e alto). Calculou-se ainda a prevalência de consumo dos alimentos, consumidos por pelo menos metade dos avaliados. A análise estatística dos dados foi efetuada por meio do teste c² e teste t de Student. Adotou-se p < 0,05 como nível de significância. RESULTADOS: Dos indivíduos estudados (n = 229), 74,2% pertenciam ao sexo feminino. A média de idade do grupo foi de 70,1 (6,4) anos. A média diária de IG do grupo caso foi de 62,3 (6,5), e do grupo controle de 62,1 (6,1), com p = 0,864. As médias diárias de CG não foram estatisticamente diferentes (p = 0,212), sendo a do grupo caso de 99,8 (33,8) e do grupo controle de 108,9 (45,7). Os alimentos consumidos tanto pelos casos como pelos controles, com maior contribuição ao IG, foram: pão, arroz, banana e açúcar refinado. CONCLUSÃO: No grupo avaliado, não houve associação entre índice glicêmico e carga glicêmica dietéticos e síndrome metabólica. O padrão identificado, no entanto, coloca portadores e não portadores em situação de risco à saúde, merecendo ações educativas.

Abstract
OBJECTIVE To determine the prevalence of metabolic syndrome (MetS) and its components and to evaluate the relationship between this diagnosis and cardiovascular risk factors, demographic and socio-economic variables. DESIGN A cross-sectional study using a questionnaire including information on sociodemographic and CVD risk factors. Blood pressure, anthropometric indices, fasting glucose and lipid profile were measured. MetS was defined according to the criteria of the National Cholesterol Education Program, Adult Treatment Panel III. SETTING The whole Tunisian territory; Transition and Health Impact in North Africa (TAHINA) project. SUBJECTS A total of 4654 individuals (1840 men and 2814 women), aged 35 to 74 years, who participated in the Tunisian national survey. RESULTS The overall prevalence of MetS was 30·0 %, higher in women (36·1 %) than in men (20·6 %; P < 0·001). In both genders MetS prevalence increased significantly with age (P < 0·001), but this increase was more important in women. Multiple regression analyses showed that the odds for MetS increased significantly with urban area for both men and women (P < 0·05 and P < 0·001, respectively). The multivariate models showed also that the odds for MetS increased significantly with increasing level of education and in those with a family history of CVD for men (both P < 0·05) and after the menopausal transition for women (P < 0·05). CONCLUSIONS The study highlights the MetS problem in a middle-income developing country. There is an urgent need for a comprehensive, integrated, population-based intervention programme to ameliorate the growing problem of MetS in Tunisians.

Abstract
OBJECTIVE: To analyze subjective aspects of eating habits and self-care of patients living with chronic symptoms linked to metabolic syndrome. METHODS: A clinical and qualitative (exploratory, non-experimental) study, conducted with an intentionally small sample of nine patients in treatment at an outpatient endocrinology clinic of a university hospital in São Paulo, Brazil. The sample was closed when data saturation occurred. The in-depth interviews were conducted with a psychodynamic orientation toward the conduct of dialogues. The categorization of the discourse was developed through content analysis. The psychodynamic approach provided a theoretical reference complemented by social anthropology. RESULTS: Eating habits have been revealed as mediators of autonomy and as a source of vulnerability in the process of coping with chronic illness. Reception and understanding of the psychological and cultural aspects of food are needed in treatment faced with the difficulty of establishing changes in eating behavior. CONCLUSION: This is a contribution of an interdisciplinary approach that values listening subjectivity during treatment.

Abstract
OBJETIVO: verificar a prevalência de obesidade entre adultos das 86 famílias agricultoras de um bairro de Petrópolis, RJ, e analisar seus determinantes socioculturais. MÉTODOS: estudo quantitativo e qualitativo sobre nutrição, práticas alimentares e de trabalho realizado em 2008. Dados antropométricos foram coletados por inquérito nutricional domiciliar e o material qualitativo por observação participante e entrevistas. RESULTADOS: a prevalência de obesidade foi baixa (9,3%) entre os homens, mas bastante elevada entre as mulheres (29,9%). A prática agrícola local implica em atividade física leve para mulheres e intensa para homens. Essa diferença não é acompanhada na dieta, semelhante para homens e mulheres, com predomínio de alimentos de alto valor calórico. A produção familiar objetiva essencialmente a venda. A agricultura mercantil e a decorrente especialização dos cultivos favorecem comprar alimentos no mercado em vez de produzir para autoconsumo. CONCLUSÃO: os aspectos socioculturais e ocupacionais estudados podem ter contribuído para elevar a prevalência de obesidade nas mulheres e podem ser úteis no estudo de outros grupos com características semelhantes. Esta pesquisa ratifica a importância de estudar a obesidade em nível local, integrando abordagens quantitativas e qualitativas para identificar possíveis limitações e portas de entrada para ações de intervenção localmente relevantes.

Abstract
Síndrome Metabólica (SM) é uma condição de prevalência elevada e crescente. Este artigo tem como objetivo descrever os determinantes e também a prevalência deste importante fator de risco para doenças cardiovasculares em uma área rural do município de Santa Rosa. Foi realizado um estudo transversal, em uma população de abrangência da Estratégia Saúde da Família, constituída de adultos jovens na faixa etária de 20 a 49 anos. Foi aplicado um questionário pré-codificado com variáveis sociodemográficas, comportamentais, histórico pessoal e familiar de doenças crônicas, bem como obtidas medidas antropométricas e laboratoriais pertinentes. Para a classificação da Síndrome Metabólica, esta pesquisa seguiu os critérios da National Cholesterol Education Program’s Adult Treatment Panel (NCEP/ATP III) e da International Diabetes Federation. Foram descritos componentes isolados da SM, encontrando alta prevalência de obesidade abdominal e HDL - colesterol baixo em mulheres, bem como alta prevalência de níveis pressóricos aumentados em homens. A prevalência global da SM encontrada foi de 8,5% em homens e 22% em mulheres pelos critérios da NCEP/ATP III, e 15,9% em homens e 25,3% em mulheres pelos critérios da IDF.

Abstract
Pacientes obesos mórbidos têm recorrido à cirurgia bariátrica como um recurso eficaz para perder peso. Entretanto, este procedimento pode causar alterações comportamentais significativas. O objetivo deste trabalho foi investigar os níveis de ansiedade e depressão, assim como as mudanças sofridas na percepção da imagem corporal em pacientes obesos submetidos à cirurgia bariátrica em três momentos: pré-operatório, 6 meses e 12 meses após a cirurgia. Trata-se de um estudo do tipo prospectivo longitudinal, de abordagem quantitativa. No estudo foram aplicados os Inventários de Depressão e Ansiedade de Beck e a Escala Brasileira de Figuras de Silhuetas para Adultos. A cirurgia diminuiu significativamente tanto o índice de massa corporal dos pacientes quanto a insatisfação com a sua imagem corporal. Essa perda de peso e diminuição da insatisfação com a imagem corporal foi acompanhada de redução nos níveis de ansiedade e depressão, o que sugere que estes são fatores importantes no quadro obesidade.

Abstract
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/m2) and muscle-mass index (MMI kg/m2). 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.

Abstract
INTRODUCTION Metabolic syndrome (MetS), a risk factor for atherosclerosis and coronary heart disease, is related to an inadequate food intake pattern. Its incidence is increasing among Brazilian adults, including those living in rural areas. Our aim was not only to describe the frequency of MetS in adults with or without MetS but also to compare their food intake pattern as assessed by the healthy eating index (HEI) and serum albumin and C reactive protein (CRP) levels. METHODS Men and women (n = 246) living in a small village in Brazil were included. MetS was characterized according to the adult treatment panel (ATP III) criteria. Groups were compared by chi-square, student t or Mann-Whitney tests. RESULTS MetS was diagnosed in 15.4% of the cases. The MetS group showed higher CRP (1.8±1.2 vs. 1.0±0.9 mg/dl) and lower albumin (4.3±0.3 vs. 4.4±0.3 g/dl) serum levels compared to the control group. Additionally, the MetS group showed lower scores (median[range]) in the HEI compared to the control group (53.5[31.2-78.1] vs 58[29.7-89.5], respectively). The MetS group also had decreased scores for total fat and daily variety of food intake. CONCLUSIONS The results suggest that adults with MetS displayed chronic mild inflammation and a poorer food intake pattern than the control group.

Abstract
Schistosomes are blood-dwelling flukes which are highly dependent on the host metabolism. The aim of this study was to investigate possible relationship between streptozotocin-induced diabetes and the outcome of acute murine schistosomiasis mansoni. Male and female SW mice were treated by a single intraperitoneally injected dose of streptozotocin (180 mg/kg). Seven days after induction, both control and diabetic animals were infected with 70 Schistosoma mansoni cercariae (BH strain). Diabetics and their controls were weighed 45 days after birth and for the last time prior to killing. Susceptibility to infection was evaluated twice a week by quantifying fecal egg excretion 7-9 weeks post-infection by the Kato-Katz' thick smear method. Mice were euthanized the day after the last fecal examination was performed. Adult worms were recovered from the portal system and mesenteric veins, whereas liver and intestine were removed for enumeration of egg load. No differences in worm length or in measurements of the reproductive organs, tegument, and suckers were detected. Also oviposition was unaffected as the total number of eggs per female worm from the liver, the small and the large intestine was the same in both groups. An oogram evaluation revealed a lower percentage of mature (23.0% vs. 40.7%) and a higher percentage of immature (69.1% vs. 51.7%) eggs in the small intestine of the diabetic mice. We suggest that principally a hampered egg passage through the intestine tissue caused this reduction and that probably both the eggs and the impaired host response play a role.

Abstract
OBJECTIVE To assess the available data on the prevalence of metabolic syndrome (MS) in Latin-American countries. DESIGN Systematic review. Searches were carried out in PubMed, ISIWeb, SCielo and Redalyc, using 'metabolic syndrome x' and 'prevalence' as keywords for titles and/or abstracts. Articles selected were cross-sectional studies in Latin-American countries, whose main objective was to study MS and whose study population is described below. MS must be determined using Adult Treatment Panel III criteria. Twelve studies with these criteria were selected, one of which was multi-centric. SETTING Latin America. SUBJECTS Apparently healthy subjects aged 18-65 years (including young adult, mature adult and elderly populations) of both genders. RESULTS The general prevalence (weighted mean) of MS in Latin-American countries was 24·9 (range: 18·8-43·3) %. MS was slightly more frequent in women (25·3 %) than in men (23·2 %), and the age group with the highest prevalence of MS consisted of those over 50 years of age. The most frequent components of MS were low HDL cholesterol levels (62·9 %) and abdominal obesity (45·8 %). Similar outcomes were obtained from the multi-centre study on Latin-American populations analysed. CONCLUSIONS The present review brings us closer to an understanding of the prevalence of MS in Latin-American countries. However, it is not possible to know the full scope of the problem, partly because data from some countries are not available, and because the methodological differences among the studies published up to the present limit a joint analysis of their results.

Abstract
CONTEXT AND OBJECTIVE Early diagnosis of prediabetes should be done to avoid complications relating to diabetes mellitus (DM). The aim here was to assess the prevalence of prediabetes among individuals at high risk of developing DM, and to seek variables relating to glucose intolerance (GI) among individuals with normal fasting plasma glucose (FPG). DESIGN AND SETTING Cross-sectional study at Hospital do Servidor Público Estadual, São Paulo. METHODS The FPG and glucose tolerance test (GTT) were analyzed, from which the subjects were divided as follows: group 1 (FPG and GTT both normal), group 2 (normal FPG but abnormal GTT), group 3 (abnormal FPG but normal GTT), and group 4 (FPG and GTT both abnormal). The subjects' clinical, laboratory and anthropometric profile was determined. RESULTS 138 subjects were studied: 44 in group 1, 11 in group 2, 33 in group 3 and 50 in group 4. The prevalence of prediabetes was 68.0%. Group 4 individuals were older than group 1 individuals [69.0 (55.5-74.0) versus 58.9 ± 11.8 years; P < 0.05], with greater prevalence of risk conditions for DM [5.0 (4.0-5.0) versus 4.0 (3.0-5.0); P < 0.05]. Among individuals with normal FPG, GI prevalence was 20.0%. No variables analyzed correlated with GTT. CONCLUSION The prevalence of prediabetes was 68.0%, and 20.0% of subjects with normal FPG had GI. Although some anthropometric, clinical and laboratory variables have been correlated with DM and prediabetes, none, except for GTT, was able to screen for GI among subjects with normal FPG in the present study.

Abstract
OBJETIVO: Estimar os níveis de atividade física e sua associação com fatores sociodemográficos em moradores de áreas rurais. MÉTODOS: Estudo transversal, de base populacional, incluindo 567 adultos de duas comunidades rurais do Vale do Jequitinhonha, MG, entre os anos de 2008 e 2009. Os níveis de atividade física foram coletados por meio do Questionário Internacional de Atividade Física, versão longa adaptada. Utilizou-se o ponto de corte de 150 minutos de atividade física semanal entre os domínios: trabalho, domicílio, lazer e deslocamento. Os fatores sociodemográficos pesquisados foram sexo, cor da pele, idade, estado marital, escolaridade e autopercepção de saúde. Foram realizadas análise bivariada (qui-quadrado, p< 0,05) e análise múltipla de regressão logística. RESULTADOS: A prevalência de indivíduos que praticaram 150 minutos ou mais de atividade física no trabalho foi de 82,9% (IC 95%: 77,8;88,0) entre os que trabalham atualmente. Essa proporção para os outros domínios foram: domicílio 63,5% (IC 95%: 59,6;67,4); lazer 10,1% (IC 95%: 7,6;12,6); e no deslocamento 32,0% (IC 95%: 28,2;35,8). Os homens foram mais ativos que as mulheres no lazer, deslocamentos e trabalho, enquanto as mulheres foram mais ativas no ambiente doméstico. A atividade física de lazer foi mais prevalente em indivíduos de maior escolaridade, mais jovens e entre os de cor preta e parda. No deslocamento, mulheres mais jovens e homens e mulheres com estado de saúde excelente/bom foram mais ativos. Os homens com maior escolaridade foram os menos ativos neste domínio. CONCLUSÕES: A prevalência de adultos fisicamente ativos em área rural é alta, mas os níveis de atividade física no lazer são baixos e seguem padrões similares aos de áreas urbanas segundo idade, sexo e escolaridade.

Abstract
OBJECTIVE To investigate cut-off values for HOMA1-IR and HOMA2-IR to identify insulin resistance (IR) and metabolic syndrome (MS), and to assess the association of the indexes with components of the MS. METHODS Nondiabetic subjects from the Brazilian Metabolic Syndrome Study were studied (n = 1,203, 18 to 78 years). The cut-off values for IR were determined from the 90th percentile in the healthy group (n = 297) and, for MS, a ROC curve was generated for the total sample. RESULTS In the healthy group, HOMA-IR indexes were associated with central obesity, triglycerides and total cholesterol (p < 0.001). The cut-off values for IR were: HOMA1-IR > 2.7 and HOMA2-IR > 1.8; and, for MS were: HOMA1-IR > 2.3 (sensitivity: 76.8%; specificity: 66.7%) and HOMA2-IR > 1.4 (sensitivity: 79.2%; specificity: 61.2%). CONCLUSION The cut-off values identified for HOMA1-IR and HOMA2-IR indexes have a clinical and epidemiological application for identifying IR and MS in Westernized admixtured multi-ethnic populations.

Abstract
Objectives. We determine the prevalence of the metabolic syndrome in an urban population of Zanjan, a province located to the west of Tehran. Methods. Randomly selected adults >20 years were studied using stratified sampling. Target study sample was 2941 (1396 males and 1545 females). Metabolic syndrome was diagnosed using Adult Treatment Panel-III (ATP-III) guidelines when any three of the following were present: central obesity, raised triglycerides ≥150 mg/dl, low high-density lipoprotein (HDL) cholesterol, blood pressure ≥ 130/ ≥ 85 mm Hg, and diabetes or fasting plasma glucose (FPG) ≥ 100 mg/dl. Results. Metabolic syndrome was present in 697 (23.7%) subjects (CI 95%:22%–25%, P = .001), prevalence was 23.1% in men and 24.4% in women (P : .4). The prevalence increased from 7.5% in the population younger than 30 y to 45.6% in ages more than 50 years. Low HDL was the most common metabolic abnormality in both sexes. Most of those with metabolic syndrome had three components of the syndrome (75.6%), 170 subjects (24.4%) had four and none had five components simultaneously. The prevalence of obesity (BMI ≥ 30 kg/m2), hypercholesterolemia (≥200 mg/dl) and high LDL cholesterol (≥130 mg/dl) was greater in the metabolic syndrome group than normal subjects (P = .00). Conclusions. There is a high prevalence of metabolic syndrome in this urban population of the northern west of Iran. Focus of cardiovascular prevention should be undertaken in this area.

Abstract
O objetivo deste estudo foi verificar os padrões de agrupamento das variáveis antropométricas e metabólicas relacionadas com a síndrome metabólica, de acordo com o sexo. Foram coletados dados de 579 moradores de duas comunidades rurais brasileiras, com idades entre 18 e 94 anos. A análise fatorial foi realizada utilizando-se o método de extração de componentes principais e rotação ortogonal varimax. Este estudo reduziu um grupo complexo de fatores de risco cardiovascular que caracterizam a síndrome metabólica em três fatores independentes, cada um refletindo um aspecto diferente da síndrome metabólica. Em ambos os sexos, o fator 1 esteve relacionado à obesidade e dislipidemia, o fator 2 à obesidade e pressão arterial e o fator 3 à obesidade e resistência à insulina. As variâncias totais explicadas para os sexos masculino e feminino foram, respectivamente, 66,61% e 68,98%. Esses achados corroboram com a hipótese de que pelo menos três processos fisiopatológicos atuam no agrupamento dos fatores de risco cardiovasculares na população rural estudada.

Habilidade de indicadores antropométricos e de composição corporal em identificar a resistência à insulina. ACTA ACUST UNITED AC 2009; 53:72-9. [DOI: 10.1590/s0004-27302009000100011] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2008] [Accepted: 10/27/2008] [Indexed: 11/22/2022]
Abstract
OBJETIVOS: Avaliar a habilidade de indicadores antropométricos e de composição corporal em identificar a resistência à insulina (RI), determinando-se os pontos de corte para os que apresentarem melhor eficácia. MÉTODOS: Foram avaliados 138 homens. Determinou-se: perímetro da cintura (PC), diâmetro abdominal sagital (DAS), índice de conicidade (IC), índice de massa corporal (IMC), percentual de gordura corporal (%GC), índice sagital (IS) e relações cintura-estatura (RCE), cintura-quadril (RCQ) e cintura-coxa (RCCoxa). A RI foi avaliada pelo HOMA-IR. Utilizou-se análise de correlação e análise ROC, com determinação das áreas abaixo da curva (AUC). RESULTADOS: O DAS (r = 0,482; AUC = 0,746) e o PC (r = 0,464; AUC = 0,739) apresentaram correlações mais fortes com o HOMA-IR e maior poder discriminante para RI (p < 0,001), sendo seus melhores pontos de corte 89,3 cm e 20,0 cm, respectivamente. CONCLUSÃO: Os indicadores de obesidade central, o PC e o DAS demonstraram maior habilidade em identificar RI em homens. Encoraja-se a realização de estudos com mulheres e idosos na busca dos melhores pontos de corte para toda a população.

Abstract
This article reviews 69 original research articles published in 6 Brazilian Medical Journals recently incorporated into the Institute for Scientific Information Journal of Citation Reports, with a view of making them comprehensively available to the readership of CLINICS within a subject category division. We expect this review to increase the visibility of a wide specter of original Brazilian research which may otherwise remain relatively unseen by the interested readership.

The effects of high fat on central appetite genes in Wistar rats: a microarray analysis. Clin Chim Acta 2008; 397:96-100. [PMID: 18721800 DOI: 10.1016/j.cca.2008.07.027] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2008] [Revised: 07/25/2008] [Accepted: 07/25/2008] [Indexed: 11/22/2022]
Abstract
BACKGROUND To evaluate the effects of high fat on central appetite regulatory genes in Wistar rats by microarray. METHODS Sixteen male Wistar rats were randomly assigned to control (15% energy from fat) and high-fat (60% energy from fat) diets for 12 weeks. Body weight and food intake were recorded. Plasma leptin, ghrelin and insulin were measured by radioimmunoassay method. The expression of 111 appetite regulatory genes in the hypothalamus was evaluated by microarray and six genes, including leptin receptor, insulin receptor, orexin, NPY, AgRP, MC-4R, were further evaluated by real-time RT-PCR. RESULTS Body weight increased significantly in HF group compared with control group, whereas energy intake was similar in the two groups. HF had a time dependent effect on plasma leptin, but insulin and ghrelin level remained stable throughout the study. A positive relation was also found between body weight and plasma leptin (r=0.88, P<0.01). The expression of 27 appetite genes in the hypothalamus was significantly affected by HF diet. However, only the expression of leptin receptor was confirmed lower in HF group than that in control by real-time PCR, which suggested that lower expression of leptin receptor might be another reason for leptin resistance. CONCLUSIONS HF diet fed rats demonstrated leptin resistance, which could be targeted for obesity treatment.
