RESUMEN
BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Coronary artery calcification is an early marker of subclinical atherosclerosis, but little research has been done in asymptomatic individuals under 45 years. In this cohort study with 17 years of follow-up, 155 participants were assessed in 2016 with a coronary calcium score for the association with cardiovascular risk factors. During follow-up, there was a significant increase in anthropometric measurements, cholesterol and fractions, and diastolic pressure. Participants who gained 1 cm in waist circumference had a mean reduction of 0.36 mg/dL in HDL-cholesterol and those who gained 1 kg/m2 in body mass index had a reduction of 0.72 mg/dL in HDL-cholesterol. Married participants had a 4.78 mg/dL reduction in HDL-cholesterol levels compared to singles. There was an increase of 2.09 mg/dL in HDL-cholesterol at each higher level of self-perceived health. One single case, a 32-year-old male, smoker, sedentary individual with a family history of cardiovascular disease, presented coronary calcification (0.6%). His HDL-cholesterol was reduced by 43.4%, with levels of less than 25 mg/dL at the time of coronary calcium scoring. Our findings may prompt broader studies of populations under 35 years with HDL-C levels below 25 mg/dL and family histories of cardiovascular disease, associated with obesity, sedentary lifestyle and smoking.

This article reports the rationale for the Brazilian Cardioprotective Nutritional Program (BALANCE Program) Trial. This pragmatic, multicenter, nationwide, randomized, concealed, controlled trial was designed to investigate the effects of the BALANCE Program in reducing cardiovascular events. The BALANCE Program consists of a prescribed diet guided by nutritional content recommendations from Brazilian national guidelines using a unique nutritional education strategy, which includes suggestions of affordable foods. In addition, the Program focuses on intensive follow-up through one-on-one visits, group sessions, and phone calls. In this trial, participants 45 years or older with any evidence of established cardiovascular disease will be randomized to the BALANCE or control groups. Those in the BALANCE group will receive the afore mentioned program interventions, while controls will be given generic advice on how to follow a low-fat, low-energy, low-sodium, and low-cholesterol diet, with a view to achieving Brazilian nutritional guideline recommendations. The primary outcome is a composite of death (any cause), cardiac arrest, acute myocardial infarction, stroke, myocardial revascularization, amputation for peripheral arterial disease, or hospitalization for unstable angina. A total of 2468 patients will be enrolled in 34 sites and followed up for up to 48 months. If the BALANCE Program is found to decrease cardiovascular events and reduce risk factors, this may represent an advance in the care of patients with cardiovascular disease.

OBJECTIVE: To evaluate the effectiveness of a nutritional strategy based on two components and adapted for the public health system on blood pressure, cardiometabolic features, self-care, qualify of life and diet quality in individuals with hypertension. METHODS: NUPRESS was an open-label, parallel-group, superiority randomized controlled clinical trial in which participants at least 21âyears with hypertension and poorly controlled blood pressure were randomly assigned (1â:â1 allocation ratio) to either an individualized dietary prescription according to nutritional guidelines (control group, n â=â205); or a two-component nutrition strategy, including a goal-directed nutritional counseling and mindfulness techniques (NUPRESS [intervention] group, n â=â205). Primary outcomes were SBP (mmHg) after 24 weeks of follow up and blood pressure control, defined as either having SBP more than 140âmmHg at baseline and achieving 140âmmHg or less after follow-up or having SBP 140âmmHg or less at baseline and reducing the frequency of antihypertensive drugs in use after follow-up. RESULTS: In total, 410 participants were randomized and submitted to an intention-to-treat analysis regarding primary outcomes. Both groups decreased blood pressure, but after adjusting for baseline values, there was no significant difference between them on SBP [intervention-control difference: -0.03 (-3.01; 2.94); P â=â0.98] nor blood pressure control [odds ratio 1.27 (0.82; 1.97); P â=â0.28]. No differences between groups were also detected regarding secondary and tertiary outcomes. CONCLUSION: There was no difference between a two-component nutritional strategy and an established dietary intervention on blood pressure in participants with hypertension.

The older population has an increasing burden of non-communicable disease, which can potentially be associated with physical and mental disabilities and shorten life spam. To investigate whether depression, loss of functionality for activities of daily living, and lower social support are associated with all-cause mortality in the older population of Italian descent. This population-based cohort study was conducted in Veranópolis, a country city from southern Brazil, among individuals aged 60 years or older. Interviews were performed in a systematic random sampling regarding demographic, socioeconomic, and psychosocial variables, in addition to depression (Geriatric Depression Scale), activities of daily living (Barthel Index), and social support (Medical Outcomes Study scale). In the follow-up, participants were reinterviewed or, in case of death, the next of kin, and hospital records were revised. Hierarchical analysis was used to determine characteristics independently associated with all-cause mortality, using Poisson regression with robust variance, expressed as relative risk with 95% confidence intervals (RR; 95%CI). A total of 997 participants were enrolled and 882 participants completed the study, after 7.24 ± 2.41 years; with 581 remaining alive. The mean age was 73.12 ± 8.03 years, 4% were nonagenarians or centennials, and 62% were women. Symptoms of depression (RR: 1.04; 1.01-1.06) and functional dependence for ADL (RR: 1.00; 0.99-1.00) were associated with all-cause mortality, even after controlling for confounding factors. Lower social support was not associated with mortality (RR: 1.00; 0.99-1.01). Depression and functional dependence are independent predictors of all-cause mortality in the older population from Italian descent.

BACKGROUND: Identifying asymptomatic individuals at risk of developing cardiovascular disease is one of the main goals of preventive cardiology. The coronary calcium score (CCS) makes it possible to estimate vascular age, which has shown to be more reliable than chronological age for determining cardiovascular risk. OBJECTIVES: To reclassify cardiovascular risk based on arterial age and evaluate CCS progression during follow-up. METHODS: We included 150 asymptomatic men who underwent clinical and CCS evaluation in 2 evaluations with an interval of 7.6 years. We classified patients by traditional risk scores and arterial age. We evaluated which variables were associated with greater CCS progression during the period, considering a statistical significance level of 5% (p < 0.05). RESULTS: The use of arterial age in the stratification of cardiovascular risk in comparison with the Framingham risk score (FRS) reclassified 29% of individuals to a higher risk category and 37% to a lower risk category. Regarding the American Heart Association and American College of Cardiology score (ASCVD), 31% were reclassified as higher risk and 36% as lower risk. The initial classification by arterial age was directly related to the progression of CCS throughout follow-up (p < 0.001). This was not observed for the FRS (p = 0.862) or ASCVD (p = 0.153). The individual variables most associated with CCS progression were high systolic blood pressure and low HDL. CONCLUSION: Cardiovascular risk stratification using arterial age showed a better association than the FRS and ASCVD in identifying individuals with higher risk of atherosclerosis progression.
FUNDAMENTO: Identificar os indivíduos assintomáticos sob risco de desenvolver doenças cardiovasculares é um dos principais objetivos da cardiologia preventiva. O escore de cálcio coronariano (ECC) permite estimar a idade vascular, que se mostrou mais fidedigna que a idade cronológica na determinação do risco cardiovascular. OBJETIVOS: Reclassificar o risco cardiovascular com base na idade arterial e avaliar a progressão do escore de cálcio durante o seguimento. MÉTODOS: 150 homens assintomáticos foram submetidos a avaliação clínica e do ECC em 2 avaliações com intervalo de 7,6 anos. Classificamos os pacientes pelos escores de risco tradicionais e pela idade arterial. Avaliamos quais variáveis se associaram a maior progressão do ECC durante o período. O nível de significância estatística considerado foi de 5% (p < 0,05). RESULTADOS: A utilização da idade arterial na estratificação do risco cardiovascular em comparação ao escore de risco de Framingham (ERF) reclassificou 29% dos indivíduos para uma categoria de risco superior e 37% para uma categoria inferior. Em relação ao escore da AHA e ACC (ASCVD), 31% passaram para um risco maior e 36% para um risco menor. A classificação inicial pela idade arterial teve relação direta com a progressão do ECC ao longo do seguimento (p < 0,001), fato que não foi observado para o ERF (p = 0,862) e ASCVD (p = 0,153). As variáveis individuais que mais se associaram à progressão do ECC foram a pressão arterial sistólica e o HDL baixo. CONCLUSÃO: A estratificação de risco cardiovascular utilizando a idade arterial apresentou melhor associação que o ERF e ASCVD na identificação de indivíduos com maior risco de progressão da aterosclerose.

BACKGROUND: Risk factors for cardiovascular mortality have barely been investigated in very elderly persons and there may be differences compared with younger individuals. METHODS: This is a cohort study of all inhabitants over 80 years of age in the city of Veranópolis, Brazil. The association of demographic, anthropometric, physical, and medical characteristics with mortality by any cause and by cardiovascular disease (CVD) was investigated by means of Cox regression models. RESULTS: The mean age of the participants was 83.6 ± 3.3 years. Vital status and cause of death was ascertained in 96.9% of the participants after a mean follow-up of 8.7 ± 3.8 years. Systolic and diastolic blood pressure showed a U-shape relationship with cardiovascular and total mortality. Blood pressure lower than 140/90 mmHg was associated with a higher risk for cardiovascular mortality (HR 4.76, 95% CI 1.56-14.28, p = 0.006). Duration of sleep was inversely associated with the risk of cardiovascular death (HR 0.83, 95% CI 0.73-0.95, p = 0.007), while apoA-I was inversely associated only with the risk of all-cause mortality (HR 0.99, 95% CI 0.98-1.00, p = 0.041). Anthropometric indexes, smoking, cholesterol, LDL-cholesterol, HDL-cholesterol, and other traditional risk factors were not associated with cardiovascular mortality. CONCLUSION: Many traditional risk factors are not associated with cardiovascular mortality in the very elderly. Longer sleep duration is associated with lower cardiovascular mortality of very elderly individuals, while low blood pressure identifies very elderly individuals at higher risk of dying from cardiovascular causes.

INTRODUCTION: Parkinsonism is one of the most common neurological disorders affecting the elderly. Several population-based studies have determined the epidemiology of parkinsonism, mainly Parkinson's disease (PD), but there is still little evidence in the Brazilian population. This protocol study aims to assess the prevalence and incidence of cases of PD and other parkinsonian syndromes in a 5-year cohort in a population-based study in the southern region of Brazil. METHODS AND ANALYSIS: A prospective population-based longitudinal study, with a cohort of development of cases of parkinsonism, divided into two phases: in phase I, two questionnaires to screen for parkinsonism (Tanner's questionnaire), Rapid Eyes Movement (REM) sleep behaviour disorder (REM Sleep Behavior Disorder Single-Question Screen) and a short interview will be conducted with all elderly residents of Veranópolis (the first longevity Brazilian county located in the Rio Grande do Sul, Brazil) aged 60 or over. The positive screened cases will be examined independently by at least two movement disorder-trained physicians and prevalence will be determined. A comprehensive evaluation of prodromic symptoms, risk factors and clinical characteristics will be carried out. Subjects with subtle parkinsonism and a sample of healthy subjects will be followed for 5 years in a developmental cohort of parkinsonism cases. For crude incidence, all individuals admitted at the beginning of the study will be re-evaluated. ETHICS AND DISSEMINATION: The study was approved by the research ethics committee of the Hospital de Clínicas de Porto Alegre (protocol n° 4.095.609). All participants provide their informed consent before evaluations. Findings from this survey will be disseminated through peer-reviewed publications and will be presented at conferences.

BACKGROUND: Knowledge of environmental and genetic factors for healthy aging in elderly people is controversial. In addition to this evidence, few studies have been designed for this population. OBJECTIVES: To investigate the relationship between the most frequent apolipoprotein E (APOE) genotypes and mortality in very elderly individuals living in a community and to evaluate survival according to cardiovascular risk factors. METHODS: A sample of 74 elderly individuals aged ≥ 80 years, from the Veranópolis Project cohort, was selected for APOE genotyping. At baseline, anthropometric variables, glucose and lipid levels, blood pressure, and lifestyle variables (smoking, alcohol consumption, and physical activity) were collected. The Bayer Activities of Daily Living Scale was applied to their caregivers. Total study follow-up was 21 years. Two-sided p < 0.05 was considered statistically significant. RESULTS: There was no association between APOE genotypes and mortality. However, the risk of death in elderly smokers was 2.30 times higher (hazard ratio [HR], 95% CI 1.01 to 5.24); in individuals with diabetes, it was 3.95 times higher (HR, 95% CI 1.27 to 12.30) than in individuals without diabetes. Subjects who practiced vigorous physical activity had a 51% reduction in risk of death (HR = 0.49, 95% CI 0.27 to 0.88). For an increase of 1 mmHg in systolic blood pressure, there was a 2% reduction (HR = 0.98, 95% CI 0.97 to 0.99) in risk of death. CONCLUSION: In this sample population, APOE genotypes were not associated with mortality. However, classic cardiovascular risk factors may be important for overall mortality in the very elderly.
FUNDAMENTO: O conhecimento dos fatores ambientais e genéticos para um envelhecimento bem-sucedido em idosos longevos é controverso. Acrescenta-se a esta evidência, o fato de serem poucos os estudos delineados com essa população. OBJETIVO: Investigar a relação entre os genótipos mais frequentes da apolipoproteína E (APOE) e a mortalidade em idosos longevos que vivem em comunidade e sua sobrevida de acordo com os fatores de risco cardiovascular. MÉTODOS: Uma amostra de 74 idosos com 80 anos ou mais da coorte do Projeto Veranópolis foi selecionada para genotipagem da APOE. Na linha de base, foram coletadas variáveis antropométricas, dosagens sanguíneas de glicose e lipídeos, pressão arterial e variáveis de estilo de vida (tabagismo, consumo de álcool e atividade física). A escala Bayer de Atividades da Vida Diária foi aplicada aos cuidadores dos idosos. O tempo de seguimento total do estudo foi 21 anos. Um p<0,05 bicaudal foi considerado estatisticamente significativo. RESULTADOS: Não encontramos associação entre os genótipos da APOE e mortalidade. Entretanto, o risco de morte em idosos fumantes foi 2,30 vezes (hazard ratio [HR]; intervalo de confiança de 95% [IC 95%] 1,01 a 5,24); em diabéticos, 3,95 vezes (HR; IC 95% 1,27 a 12,30) do risco dos não diabéticos. Indivíduos que praticavam atividade física vigorosa tiveram uma redução no risco de óbito em 51% (HR = 0,49; IC 95% 0,27 a 0,88). Para o aumento de 1 mmHg na pressão arterial sistólica houve uma redução de 2% (HR = 0,98; IC 95% 0,97 a 0,99) no risco de morte. CONCLUSÃO: Nesta amostra de longevos, não houve associação entre os genótipos da APOE e mortalidade. Entretanto, os fatores de risco cardiovasculares clássicos podem ser importantes para a mortalidade geral em pessoas muito idosas.

RESUMEN
BACKGROUND AND AIMS: Computed tomography, which uses ionizing radiation and expensive software packages for analysis of scans, can be used to quantify abdominal fat. The objective of this study is to measure abdominal fat with 3T MRI using free software for image analysis and to correlate these findings with anthropometric and laboratory parameters in adolescents. METHODS: This prospective observational study included 24 overweight/obese and 33 healthy adolescents (mean age 16.55 years). All participants underwent abdominal MRI exams. Visceral and subcutaneous fat area and percentage were correlated with anthropometric parameters, lipid profile, glucose metabolism, and insulin resistance. Student's t test and Mann-Whitney's test was applied. Pearson's chi-square test was used to compare proportions. To determine associations Pearson's linear correlation or Spearman's correlation were used. RESULTS: In both groups, waist circumference (WC) was associated with visceral fat area (P = 0.001 and P = 0.01 respectively), and triglycerides were associated with fat percentage (P = 0.046 and P = 0.071 respectively). In obese individuals, total cholesterol/HDL ratio was associated with visceral fat area (P = 0.03) and percentage (P = 0.09), and insulin and HOMA-IR were associated with visceral fat area (P = 0.001) and percentage (P = 0.005). CONCLUSIONS: 3T MRI can provide reliable and good quality images for quantification of visceral and subcutaneous fat by using a free software package. The results demonstrate that WC is a good predictor of visceral fat in obese adolescents and visceral fat area is associated with total cholesterol/HDL ratio, insulin and HOMA-IR.

INTRODUCTION: Active aging is the process of optimizing opportunities for health, participation and security, aiming to improve quality of life as people age. A series of studies had demonstrated that a lower prevalence of depression is found among more active elderly. OBJECTIVE: To evaluate the association between indicators of active aging and depressive symptoms among the elderly (aged 60 years or more). METHOD: A population-based cross-sectional study was conducted with 1,006 elderly people (aged 60 years or over) from a small-sized Brazilian municipality. Depressive symptoms were assessed using the Geriatric Depression Scale - 15, with cutoff point ≥ 6 symptoms. Active aging was evaluated using indicators such as: active occupational situation, manual work, reading and physical activities. Data analyses used modified Poisson regression to obtain crude and adjusted prevalence ratios (PR). RESULTS: Most of the elderly people were: white, women and aged between 60 and 74 years. All the indicators of active aging were associated with the outcome. After controlling for socioeconomic, demographic and health variables, elderly people who worked, participated in groups, did manual work and maintained interests such as reading and talking to friends had lower prevalence of depressive symptoms compared to those not doing these activities. CONCLUSIONS: Active aging approaches may serve as a valuable mental health promotion strategy aimed at the elderly.

BACKGROUND & AIMS: To determine the relevance of waist circumference (WC) measurement and monitoring in children and adolescents as an early indicator of overweight, metabolic syndrome (MS) and cardiovascular problems in young adults in comparison with visceral and subcutaneous adiposity. METHODS: A cohort study with 159 subjects (51.6% female) started in 1999 with an average age of 13.2 years. In 1999, 2006 and 2008 weight, height, and WC were evaluated. In 2006 blood samples for laboratory diagnosis of MS were added. In 2008 abdominal computed tomography (ACT) to quantify the fat deposits were also added. RESULTS: The WC measured in children and adolescents was strongly correlated with body mass index (BMI) measured simultaneously. A strong correlation was established between WC in 1999 with measures of WC and BMI as young adults. WC strongly correlated with fat deposits in ACT. The WC in 1999 expressed more subcutaneous fat (SAT), while the WC when young adults expressed strong correlation with both visceral fat (VAT) and SAT. The correlation of WC with fat deposits was stronger in females. WC and not BMI in 1999 was significantly higher in the group that evolved to MS. CONCLUSIONS: The WC in children and adolescents was useful in screening patients for MS. WC expressed the accumulation of abdominal fat; especially subcutaneous fat.

O objetivo deste estudo foi avaliar o estado nutricional, alimentação e a saúde oral de idosos de um município da serra no Rio Grande do Sul, Brasil, por meio de um estudo transversal descritivo e analítico quantitativo, com dados primários. As variáveis analisadas foram: gênero; idade (≥60 anos); peso (kg); altura (m); índice de massa corporal (IMC=kg/m²), circunferência da cintura (CC=cm), circunferência do braço (CB=cm) e circunferência da panturilha (CP=cm). Para avaliação do estado nutricional utilizou-se a Mini Avaliação Nutricional (MAN) e o consumo alimentar foi avaliado pelo Questionário de Frequência Alimentar (QFA). Em relação à saúde bucal, aplicou-se o GOHAI (Geriatric Oral Health Assessment Index) e o EAT-10 (Instrumento de Avaliação da Alimentação). Dos 135 idosos avaliados, 71,9% eram mulheres. A obesidade abdominal foi prevalente nas mulheres (p=0,037) e o risco de desnutrição pela MAN quanto à prevalência de baixo peso pelo IMC aumentaram com a idade (p=0,021 e p=0,039). Para os demais métodos de avaliação nutricional, as diferenças não foram estatisticamente significativas. Ainda pela MAN, houve diferença significativa, onde as mulheres se perceberam com melhor saúde (p=0,030). Ao investigar a saúde oral, não houve diferença significativa (p>0,05). O consumo de frutas frescas (p=0,006) foi maior nas mulheres e batata/salgados fritos (p=0,001) foi mais consumido pelos homens. Não houve associação significativa entre os resultados da saúde oral com o consumo alimentar (p>0,05). Torna-se necessário reforçar orientações sobre alimentação saudável, para que os idosos possam adequar sua alimentação e prevenir problemas advindos de uma má nutrição, bem como, outros estudos devem ser realizados com estas variáveis.

The goal of this study was to evaluate the nutritional sate, the nourishment and the oral health of elderly people in a town located in Gaucho Highlands, Rio Grande do Sul, Brazil. It was a transversal, descriptive, qualitative analytical, with primary data. The variations analysed were: gender, age (≥60 years old), weight (kg), height (m), body mass index (BMI=kg/m²), waist circumference (WC=cm), arm circumference (AC=cm), calf circumference (CC=cm). To the evaluation, we used the "Mini Nutritional Assesment" (MNA), the food intake was evaluated by the Quizz of Nourishment Frequency (QNF), (SISVAN). For the oral health, we used the GOHAI (Geriatric Oral Health Assesment Index) and the EAT-10 (Eating Assesment Tool). From the 135 elders who were evaluated, 71.9% were women. The abdominal obesity was more important in women (p=0.037) and the risk of innutrition by MNA about the prevalence of low weight, by BMI, raised with the age (p=0.021 e p=0.039). For the other methods of nutritional evaluation, the differences weren't statistically significant. Still, by MNA there was a significant difference, where the women perceived themselves with better health (p=0.030). When investigating the oral health, there wasn't a significant difference (p>0.05). The consumption of fresh fruits (p=0.006) was bigger among the women and the consumption of potatoes/fried snacks (p=0.001) was bigger among the men. There wasn't a significant association between the results of the oral health and food consumption (p>0.05). It is necessary to reinforce guidances about healthy nourishment, so the elders can adequate their nourishment and prevent problems that come from a bad nutrition, as well as other studies must be done with these variations.

ABSTRACT: Introduction: Active aging is the process of optimizing opportunities for health, participation and security, aiming to improve quality of life as people age. A series of studies had demonstrated that a lower prevalence of depression is found among more active elderly. Objective: To evaluate the association between indicators of active aging and depressive symptoms among the elderly (aged 60 years or more). Method: A population-based cross-sectional study was conducted with 1,006 elderly people (aged 60 years or over) from a small-sized Brazilian municipality. Depressive symptoms were assessed using the Geriatric Depression Scale - 15, with cutoff point ≥ 6 symptoms. Active aging was evaluated using indicators such as: active occupational situation, manual work, reading and physical activities. Data analyses used modified Poisson regression to obtain crude and adjusted prevalence ratios (PR). Results: Most of the elderly people were: white, women and aged between 60 and 74 years. All the indicators of active aging were associated with the outcome. After controlling for socioeconomic, demographic and health variables, elderly people who worked, participated in groups, did manual work and maintained interests such as reading and talking to friends had lower prevalence of depressive symptoms compared to those not doing these activities. Conclusions: Active aging approaches may serve as a valuable mental health promotion strategy aimed at the elderly.
RESUMO: Introdução: Envelhecimento ativo é o processo de otimizar oportunidades para a saúde, participação e segurança, de modo a promover qualidade de vida enquanto as pessoas envelhecem. Estudos demonstram que menores prevalências de depressão são encontradas em idosos fisicamente ativos. Objetivo: Avaliar a associação entre indicadores de envelhecimento ativo e sintomas depressivos em idosos (60 ou mais anos de idade). Métodos: O delineamento foi transversal de base populacional. Entrevistas estruturadas foram realizadas com 1.006 idosos, pessoas com idade igual ou superior a 60 anos, residentes em um município de pequeno porte do Sul do Brasil. Sintomas depressivos foram mensurados através da Escala de Depressão Geriátrica com ponto de corte maior ou igual a seis pontos. O envelhecimento ativo foi avaliado com indicadores tais como: participação em grupos, situação ocupacional ativa, trabalhos manuais, leituras, conversa com amigos e atividades físicas. A análise dos dados utilizou Regressão de Poisson para obter as razões de prevalência (RP) brutas e ajustadas. Resultados: A maioria dos idosos eram mulheres, idade entre 60 e 74 anos e cor da pele branca. Todos os indicadores de envelhecimento ativo estavam associados com o desfecho. Após o controle para aspectos sociodemográficos, psicossociais e variáveis relacionadas à saúde, idosos com situação ocupacional ativa, que participavam em grupos, que relatavam realizar trabalhos manuais, com hábito de leitura e de socializar com os amigos possuíam menores prevalências de sintomas depressivos quando comparados àqueles que realizavam tais atividades. Conclusões: Abordagens com foco no envelhecimento ativo podem ser uma estratégia importante para promoção da saúde mental em idosos.

Objetivo: Analisar as medidas antropométricas dos escolares de Veranópolis, Rio Grande do Sul, sul do Brasil, considerando a incidência de obesidade e sobrepeso e a sua relação com o tipo de escola frequentada (pública ou privada). Métodos: Estudo transversal envolvendo todos os escolares da rede pública e privada de Veranópolis-RS a partir de uma coorte iniciada em 2012. As medidas estudadas foram peso, altura e índice de massa corporal. Todos os pais ou responsáveis pelos escolares amostrados responderam a um questionário padronizado sobre antecedentes médicos pessoais e familiares. Para o diagnóstico de sobrepeso e obesidade foram usados os critérios da Organização Mundial da Saúde (OMS) e do Centro de Controle e Prevenção de Doenças (CDC-USA). Na análise dos dados foram usadas a estatística descritiva e inferencial. Resultados: Foram amostrados 2150 escolares entre 6 e 18 anos de idade, sendo 1725 (80%) de escolas públicas e 425 (20%) de escolas privadas. A maioria da população era caucasiana (85,3%) e moradora de zona urbana (89%). Entre os escolares menores de 10 anos, utilizando-se percentil ou escore Z, a prevalência de sobrepeso e obesidade foi de 21% e de baixa estatura de 1,4%. A obesidade medida pelo IMC (percentil) foi mais prevalente em escolares menores de 10 anos (23,8 vs 16,4; p< 0,05). Para essa faixa etá- ria, a distribuição de sobrepeso e obesidade não demonstrou diferença estatisticamente significativa entre escolas públicas e privadas. Entretanto, para os escolares com idade entre 10 e 18 anos, a obesidade foi significativamente mais prevalente nas escolas públicas, tanto utilizando percentil (17,5 vs 6,7%; p< 0,05), quanto escore Z (15,8 vs 5,6%; p< 0,05). Conclusões: O sobrepeso e a obesidade são condições clí- nicas muito frequentes entre escolares de Veranópolis-RS, concordando com estatísticas nacionais e internacionais. A prevalência de obesidade é maior entre escolares menores de 10 anos, sem diferenças na distribuição por escolas públicas ou privadas. Entretanto, na faixa entre 10 e 18 anos, a prevalência de obesidade é mais significativa nas escolas públicas, indicando a participação de um forte componente social, ambiental e educacional na sua origem. Outros fatores de risco para o desenvolvimento da obesidade entre escolares devem ser estudados (AU)
Objective: To analyse the anthropometric measurements of Veranópolis (Rio Grande do Sul, south of Brazil) students, whereas the incidence of obesity and overweight and the association of these clinical conditions with the type of school attended (public or private). Methods: A cross-sectional study involving all students of public and private schools of Veranópolis-RS from a cohort initiated in 2012. Anthropometric measures were weight, height and body mass index. All parents or guardians by the sampled students responded to a standardized questionnaire, involving personal medical and family background. For the diagnosis of overweight and obesity, criteria from the WHO and CDC were used. For data analysis, descriptive and inferential statistics were performed. Results: We sampled 2150 students between 6 and 18 years of age, being 1725 (80%) of public schools and 425 (20%) of private schools. The majority of the population was Caucasians (85.3%) and resident of an urban zone (89%). Among the students under 10 years of age, using percentile or Z-score, the prevalence of overweight and obesity was 21% and short stature was 1.4%. Obesity, as measured by BMI (percentile), was more prevalent in students under 10 years of age (23.8 vs 16.4; p < 0.05). For this age group, the distribution of overweight and obesity did not show statistically significant difference between public and private schools. However, for students aged between 10 and 18 years, obesity was significantly more prevalent in public schools, both using percentile (17.5 vs. 6.7%; p < 0.05) or Z-score (15.8 vs. 5.6%; p < 0.05). Conclusions: Overweight and obesity are very common medical conditions among students of Veranópolis-RS, according to national and international statistics. The prevalence of obesity is higher among students under 10 years of age, without differences in distribution by public or private schools. However, in the range between 10 and 18 years of age, the prevalence of obesity is more significant in the public schools, indicating a strong social, environmental and educational component at its source. Other risk factors for the development of obesity among students between 6 and 18 years of age must be studied (AU)

BACKGROUND: The metabolic syndrome is a complex metabolic disturbance due to an interaction between genetic factors, poor dietary habits and physical inactivity. AIMS: To investigate the role of dietary intake on the prevalence of the metabolic syndrome in a population of elderly, socially active women in Brazil. PATIENTS AND METHODS: A total of 284 women with mean age 69.3 ± 6.3 years were evaluated in a cross-sectional retrospective study. The metabolic syndrome was diagnosed according to criteria of the International Diabetes Federation. The dietary intake was evaluated through a questionnaire for 24-hour dietary recall. The groups with or without the metabolic syndrome were compared for dietary intake and risk factors for metabolic syndrome by the multiple regression model adjusted for age, smoking, physical activity, educational level, total energy intake and fiber contents of the diet. The odds ratio for the presence of the metabolic syndrome was calculated for each nutrient by quartile for total energy intake adjusted by the residue method. RESULTS: The prevalence of metabolic syndrome was 32% in the sample. There was not found any association between dietary intake, including all macronutrients and several micronutrients, and the presence of metabolic syndrome. CONCLUSION: No associations were observed between nutritional factors and the prevalence of the metabolic syndrome in elderly women, a result possibly due to the fact that these factors have an influence in earlier phases of life, or to a recent modification of dietary habits, which however was not able to prevent the establishment of the syndrome.
RESUMEN
Dados epidemiológicos evidenciam a hipertrigliceridemia como um fator de risco independente para doenças cardiovasculares (DCV).Hipertrigliceridemia é causada por interações entre muitos fatores genéticos e ambientais. Uma causa comum de hipertrigliceridemia é naquela condição com resistência à insulina, como a síndrome metabólica e o diabetes mellitus tipo 2. Também pode surgir secundariamente devido a utilização de vários fármacos (corticosteroides, inibidores da protease para HIV, agentes bloqueadores beta-adrenérgicos e estrogênios), ingestão elevada de carboidratos, fumo, inatividade fisica, ingestão de álcool em excesso ou como um componente do sistema endócrino e de outras doenças inflamatórias, doenças genéticas raras. Nas dislipidemias genéticas subjacentes comuns, tais causas secundárias podem levar a elevações graves e muito graves de níveis de triglicerídeos e risco de pancreatite. As mudanças nos hábitos de vida são a terapia primária para triglicerídeos elevados nesses pacientes e inclui controle de peso corporal, atividade física regular, parar de fumar, restrição de uso álcool (quando consumido em excesso) e evitar dietas ricas em carboidratos.O tratamento farmacológico depende do contexto clínico global, incluindo severidade da hipertrigliceridemia, a presença concomitante de outros distúrbios lipídicos e o risco global de doença cardiovascular do paciente.
