RESUMO
INTRODUCTION: Insulin resistance and low-grade inflammation are pathophysiological mechanisms shared by type 2 diabetes and dementia. A cluster of biomarkers that could help diagnosing cognitive dysfunction prior to the installation of insulin resistance is desirable. This ELSA sub-study examined whether a cluster of selected inflammatory biomarkers was associated with worse cognitive scores in non-diabetic participants. METHODS: A sample of 998 non-diabetic participants of ELSA-Brasil had their cognitive function assessed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD), a verbal fluency test and a trail making test. An inflammatory cluster was formed by using the k-means method. ANOVA was used to compare the tertiles of a composite global cognitive z-score with clinical and laboratory variables. Logistic regression modelling with forward stepwise model selection was performed considering cognitive performance as the outcome and the cluster as the independent variable of main interest. Models were stratified by sex and adjusted for age, insulin resistance and other confounders. RESULTS: The mean age was 45.7 ± 4.9 years and 54.8% were women, who had a higher frequency of university level, healthier behaviors and lower systolic and diastolic blood pressure (BP) levels, fasting plasma glucose, non-HDL cholesterol and E-selectin levels than men. Individuals in the highest tertile of the composite global cognitive z-score were more likely to be women, with university level, and lower mean values of body mass index, BP levels, and HOMA-IR than those in lower tertiles. Using logistic regression model, the cluster category of the highest grade of inflammation showed to be associated with worse cognitive performance in women only. CONCLUSION: The association between a cluster of inflammation and worse cognitive performance seems to be useful to identify middle-aged women at risk for cognitive decline, independently of their state of insulin resistance.

BACKGROUND: Adiponectin is an insulin-sensitizer adipocytokine endowed with neuroprotective actions. Whether adiponectin regulates neuronal functioning toward delaying cognitive decline independently of the glucose metabolism disturbance has been poorly explored. This study evaluated if the performance in cognitive tests was associated with adiponectin levels prior the development of type 2 diabetes in middle-aged individuals. METHODS: A sample of 938 non-diabetic participants of ELSA had their cognitive function assessed by the CERAD delayed word recall test, the verbal fluency test and the trail making test. Stepwise multiple linear regression using forward selection had the response to cognitive tests as the dependent variable and adiponectin as the independent variable of main interest, adjusted for glucose tolerance status and confounders. RESULTS: Mean age was 45.7 ± 4.9 years, 54.5% were women, 43.0% had high education level, 59.3% weight excess and 70.0% prediabetes. In crude model, only the delayed recall memory was associated with adiponectin levels. In an initial regression model, delayed recall memory remained independently associated with adiponectin levels and prediabetes. After complete adjustments, adiponectin but not prediabetes maintained independently associated with delayed recall memory (ß 0.067; 95% CI 0.006-0.234; p = 0.040). On the other hand, learning memory showed to be associated with prediabetes (ß 0.71 95% CI 0.17; 1.24; p = 0.009) but not with adiponectin. CONCLUSIONS: The association of memory with adiponectin in middle-aged individuals, prior overt diabetes, suggests that this adipocytokine could anticipate cognitive impairmentρ detection, when preventive strategies could be more effectively implemented. The usefulness of adiponectin to identify increased risk for cognitive dysfunction before advanced age needs to be prospectively investigated in ELSA cohort.
RESUMO
OBJECTIVE: This study aimed to compare the effects of two lifestyle intervention programs for type 2 diabetes mellitus (T2DM) prevention - traditional or interdisciplinary psychoeducation-based intervention - in daily habits and cardiometabolic risk factors and investigate the role of the psychoeducational approach for the retention of individuals in the program. SUBJECTS AND METHODS: Between 2008 and 2010, in a public health service, 183 pre-diabetic individuals were allocated to two 18-month interventions involving diet and physical activity. Physical activity, diet, quality of life (QOL) and depression and biochemical measurements were obtained. Linear mixed-effect models were used to assess the effect of the interventions. A student t test was used to compare dropouts versus non-dropouts. RESULTS: Improvements in energy intake and physical activity were greater in the interdisciplinary than the traditional intervention. A decrease in fat mass and blood pressure was more pronounced with interdisciplinary intervention. Dropouts from the traditional intervention only had higher BMI and lower fiber intake and QOL than non-dropouts. CONCLUSION: The interdisciplinary psychoeducation-based intervention revealed useful for reducing cardiometabolic risk and retaining individuals with worse health profiles. This approach represents a feasible strategy for motivating high-risk individuals to adopt a long-term healthy lifestyle.

BACKGROUND: Cardiometabolic diseases and depression are public health problems that are often related. The benefits of behavioral interventions on lifestyle are well documented. However, the influence of depression in these interventions is unclear. OBJECTIVE: To evaluate whether depression affects the impact of a lifestyle intervention on cardiometabolic response in an at-risk sample. METHODS: 129 individuals identified by the public health system to be at risk for cardiometabolic disease were allocated to 18-month interventions on diet and physical activity. Socio-demographic and clinical data were obtained. Depressive symptoms were assessed by the Beck Depression Inventory. Changes by at least 10% in each of 6 cardiometabolic risk factors were used to define responses to intervention. Logistic regression models were employed for each gender. RESULTS: Approximately 42% of individuals had depressive symptoms. They had higher adiposity, cholesterol, and blood pressure levels and lower quality of life and physical activity levels than non-depressed individuals. In adjusted models, only women with depression at baseline had lower chance of improving plasma glucose (OR: 0.32) and lower chance of improving mean blood pressure (OR: 0.29) after the follow-up, compared with non-depressed women. LIMITATIONS: The small sample size may have diminished the power of the results and the instrument used to measure depression does not provide clinical diagnosis according to DSM criteria. CONCLUSION: Depression at baseline of lifestyle interventions predicted a lower chance of improving long-term cardiometabolic risk, particularly in women, suggesting that screening and management of depression as part of lifestyle interventions can potentially improve cardiometabolic risk profile.

Introdução: Doenças crônicas não transmissíveis representam as principais morbidades da atualidade, dentre estas o diabetes mellitus (DM) tipo 2 e a depressão, as quais encontram-se frequentemente associadas. Ambas contribuem para complicações cardiovasculares e mortalidade. Há evidências de que intervenções comportamentais trazem benefícios cardiometabólicos e psicológicos. Objetivos: Para avaliar intervenção no estilo de vida, este estudo incluiu: 1) revisão sistemática e metanálise destinada a investigar os efeitos de intervenções no estilo de vida na melhora da depressão em indivíduos de risco ou com diabetes mellitus tipo 2; 2) comparação do efeito de duas intervenções no estilo de vida sobre o risco cardiometabólico e na retenção dos indivíduos ao programa; 3) análise do papel da depressão na resposta cardiometabólica às intervenções, mediada pela inflamação e; 4) avaliação do efeito residual 9 meses após término das intervenções quanto às respostas de variáveis clínicas, qualidade de vida (QV) e depressão. Métodos: Para revisão sistemática os principais bancos de dados bibliográficos foram pesquisados, sendo a meta-análise conduzida por modelos de efeito aleatório. O estudo longitudinal incluiu adultos pré-diabéticos, submetidos a 18 meses de intervenção tradicional (TRD) ou interdisciplinar com psicoeducação (INT) para mudanças em hábitos de vida, sendo os dados coletados (antropometria, pressão arterial, perfil bioquímico e marcadores de inflamação PCR, TNF-, adiponectina) no momento basal, 9 e 18 meses, bem como 9 meses após o término do acompanhamento (27 meses).
Introduction: Nowadays non-communicable chronic diseases, such as diabetes mellitus and depression, are major public health problems worldwide. These conditions are commonly associated and contribute to cardiovascular complications and mortality. Previous studies showed that motivational interviews may improve cardiometabolic and psychological aspects. Objectives: In order to assess lifestyle intervention this study includes: 1) Systematic review and meta-analysis to verify effect of lifestyle interventions on depression; 2) to compare effects of two lifestyle interventions in the cardiometabolic risk and in retention of at-risk individuals; 3) to analyze influence of depression in cardiometabolic response to interventions mediated by inflammation and, 4) to assess residual effect at 9 months after completion of interventions according to clinical variables, quality of life and depression. Methods: In the systematic review major bibliographic databases were searched. Meta-analysis was conducted by random-effects model. The effect of method, duration, and frequency of the interventions were determined via subgroup analyses. Our longitudinal study includes prediabetic adults, submitted to one of two lifestyle interventions (TRD:Traditional or INT:Interdisciplinary). Data were collected (anthropometry, blood pressure, biochemical profile and inflammation markers CRP, TNF-, adiponectin) at baseline, 9th and 18th month, as well as 9 months after completion of interventions (observational phase). Diet was evaluated by 24h recalls and physical activity by IPAQ.

BACKGROUND/OBJECTIVES: Cardioprotective effects of Mediterranean-style diet have been shown. Instead of excluding foods, replacement or addition may facilitate compliance with impact on glucose metabolism of individuals at cardiometabolic risk. This study investigated the effect of changing selected nutrients intake on glucose metabolism during a lifestyle intervention tailored to living conditions of prediabetic Brazilians. SUBJECTS/METHODS: 183 prediabetic adults treated under the Brazilian public health system underwent an 18-month intervention on diet and physical activity. Dietary counseling focused on reducing saturated fat replaced by unsaturated fatty acids. Data were collected at baseline and after follow-up. ANOVA and multiple linear regression were used to test association of changes in nutrients intake with changes in plasma glucose. RESULTS: Changes in fasting and 2-h plasma glucose but not in weight, HOMA-IR or C-reactive protein decreased after intervention across tertiles of MUFA changes (p-trend 0.017 and 0.024, respectively). Regression models showed that increase in MUFA intake was independently associated with reduction in fasting (ß -1.475, p = 0.008) and 2-h plasma glucose (ß -3.321, p = 0.007). Moreover, increase in soluble fibers intake was associated with decrease in fasting plasma glucose (ß -1.579, p = 0.038). Adjustment for anthropometric measurements did not change the results but did after including change in insulin in the models. CONCLUSIONS: Increases of MUFA and soluble fibers intakes promote benefits on glucose metabolism, independently of adiposity, during a realistic lifestyle intervention in at-risk individuals. Mechanisms mediating these processes may include mainly insulin sensitivity improvement.
RESUMO
UNLABELLED: Public health strategies to reduce cardiovascular morbidity and mortality should focus on global cardiometabolic risk reduction. The efficacy of lifestyle changes to prevent type 2 diabetes have been demonstrated, but low-cost interventions to reduce cardiometabolic risk in Latin-America have been rarely reported. Our group developed 2 programs to promote health of high-risk individuals attending a primary care center in Brazil. This study compared the effects of two 9-month lifestyle interventions, one based on medical consultations (traditional) and another with 13 multi-professional group sessions in addition to the medical consultations (intensive) on cardiometabolic parameters. Adults were eligible if they had pre-diabetes (according to the American Diabetes Association) and/or metabolic syndrome (International Diabetes Federation criteria for Latin-America). Data were expressed as means and standard deviations or percentages and compared between groups or testing visits. A p-value < 0.05 was considered significant. RESULTS: 180 individuals agreed to participate (35.0% men, mean age 54.7 ± 12.3 years, 86.1% overweight or obese). 83 were allocated to the traditional and 97 to the intensive program. Both interventions reduced body mass index, waist circumference and tumor necrosis factor-α. Only intensive program reduced 2-hour plasma glucose and blood pressure and increased adiponectin values, but HDL-cholesterol increased only in the traditional. Also, responses to programs were better in intensive compared to traditional program in terms of blood pressure and adiponectin improvements. No new case of diabetes in intensive but 3 cases and one myocardial infarction in traditional program were detected. Both programs induced metabolic improvement in the short-term, but if better results in the intensive are due to higher awareness about risk and self-motivation deserves further investigation. In conclusion, these low-cost interventions are able to minimize cardiometabolic risk factors involved in the progression to type 2 diabetes and/or cardiovascular disease.
RESUMO
The objective this study was to describe the methodology and implementation of lifestyle change program in individuals at cardiometabolic risk seen at the public health system in Sao Paulo. The Programa de Prevenção de Diabetes Mellitus (PDM) aims at improving the overall metabolic profile of individuals with prediabetes or metabolic syndrome without diabetes; its goals were > 5% weight loss, dietary fiber intake > 20 g per day, saturated fatty acids intake < 10% per day, and > 150 minutes of physical activity per week. The first edition of the PDM lasted 18 months and involved an interdisciplinary team (endocrinologist, psychologist, nutritionist, and physical educator) to plan and conduct group sessions with the participants. The structure and systematic of the sessions were planned using a psychoeducative approach in order to facilitate the process of lifestyle changes. Based on the Experience with the PDM, some reflections and recommendations are made. This study may indicate ways for health professionals to tailor local care conditions and promote a healthy lifestyle, working with a new perspective.

OBJECTIVES: Associations of leisure-time physical activity (LTPA), commuting and total physical activity with inflammatory markers, insulin resistance and metabolic profile in individuals at high cardiometabolic risk were investigated. DESIGN: This was a cross-sectional study. METHODS: A total of 193 prediabetic adults were compared according to physical activity levels measured by the international physical activity questionnaire; p for trend and logistic regression was employed. RESULTS: The most active subset showed lower BMI and abdominal circumference, reaching significance only for LTPA (p for trend=0.02). Lipid profile improved with increased physical activity levels. Interleukin-6 decreased with increased total physical activity and LTPA (p for trend=0.02 and 0.03, respectively), while adiponectin increased in more active subsets for LTPA (p for trend=0.03). Elevation in adjusted OR for hypercholesterolemia was significant for lower LTPA durations (p for trend=0.04). High apolipoprotein B/apolipoprotein A ratio was inversely associated with LTPA, commuting and total physical activity. Increase in adjusted OR for insulin resistance was found from the highest to the lowest category of LTPA (p for trend=0.04) but significance disappeared after adjustments for BMI and energy intake. No association of increased C-reactive protein with physical activity domains was observed. CONCLUSIONS: In general, the associations of LTPA, but not commuting or total physical activity, with markers of cardiometabolic risk reinforces the importance of initiatives to increase this domain in programs for the prevention of lifestyle-related diseases.

OBJECTIVE: To evaluate whether an interdisciplinary intervention program on lifestyle results in better quality of life (QoL) and lower frequencies of depression and binge eating disorder (BED) in individuals at risk for type 2 diabetes mellitus. METHODS: A total of 177 individuals (32.2% men, age 55.4 ± 12.5 years) at risk for diabetes were allocated to a 9-month traditional (TI) or intensive interdisciplinary intervention (II) on dietary habits and physical activity including psychoeducative groups. They were submitted to questionnaires and clinical and laboratory examinations. Predictors of non-adherence were analyzed by logistic regression. RESULTS: Only individuals submitted to II had blood pressure and plasma glucose levels reduced. Frequencies of depression reduced in both interventions but of BED only in II (28.0-4.0%, P < 0.001). Increments in the scores of SF-36 domains (physical functioning: 11.1 ± 14.0 vs. 5.3 ± 13.0, role-emotional: 20.4 ± 40.2 vs. 6.2 ± 43.8, P = 0.05) were greater in the II than in TI, respectively. Changes in SF-36 correlated with decreases in anthropometry, blood pressure and glucose levels, depression and BED scores. Male gender was independently associated with non-adherence to the II. CONCLUSIONS: In addition to metabolic benefits, an interdisciplinary approach may induce desirable extrametabolic effects, favoring the control of psychiatric disorders and improving the QoL of individuals at risk for diabetes.

O aumento da expectativa de vida e da prevalência de doenças crônicas, como o diabetes mellitus (DM), mudou o foco das agências governamentais de saúde. O DM causa complicações crônicas graves comprometendo a qualidade de vida (QV) e a sobrevida; em concomitância com transtornos psiquiátricos como depressão e compulsão alimentar periódica (CAP) piora adesão ao tratamento e deteriora o prognóstico. É possível que abordagem psicoeducativa reverta em melhor controle metabólico e QV por meio de programa de mudanças de hábitos de vida. Objetivo: Avaliar se intervenção no estilo de vida com abordagem intensiva interdisciplinar a indivíduos de risco para DM resulta em melhor QV que a intervenção tradicional (IT). Métodos: 177 indivíduos pré-diabéticos ou portadores de síndrome metabólica, atendidos pelo SUS, foram alocados aleatoriamente para uma IT ou intensiva (II) em hábitos de vida por 9 meses. O grupo de IT foi submetido a consultas médicas trimestrais e o grupo II, além destas, participou de 13 sessões de grupos psicoeducativos para mudanças em hábitos alimentares e atividade física. No momento basal e após 9 meses submeteram-se a exames clínico-laboratoriais e a questionários: versão longa do IPAQ, recordatórios alimentares de 24h, de QV (SF-36), para depressão (IBD e PRIME-MD) e escala de CAP. Fatores preditivos de adesão definida como participação em pelo menos 70 por cento das sessões psicoeducativas foram analisados em modelo de regressão logística. Resultados: Em ambas as intervenções houve melhora significante do IMC, circunferência abdominal e HDL. Após 9 meses, apenas os indivíduos da II reduziram pressão arterial e glicemia. O grupo II obteve melhora significante da QV na maioria dos domínios do SF-36 e nas medidas-resumo do componente físico e mental...
Longer life expectancy and high prevalence rates of chronic diseases such as diabetes mellitus (DM) have modified the focus of government health agencies. DM causes severe chronic complications deteriorating quality of life (QoL) and survival; concomitance of DM and psychiatric disorders - such as depression and binge eating (BED) - decreases compliance to treatment and deteriorates prognosis. Management of these disorders may revert in better metabolic control and QoL during programs of lifestyle changes. Objective: To assess whether lifestyle intervention with intensive interdisciplinary approach for individuals at risk for DM results in better QoL that traditional intervention (TI). Methods: 177 individuals with pre-diabetes or metabolic syndrome, seen by Brazilian public health system, were randomly allocated to an IT or intensive intervention (II) in life habits for 9 months. Individuals from TI had medical visits each three months and from II additionally attended 13 psychoeducative group sessions focusing on dietary habits and physical activities. At baseline and after 9 months, they were submitted to clinical examination and laboratory procedures and answered questionnaires: long version of IPAQ, 24-h food recalls, QoL (SF-36), for depression (BDI and PRIME-MD) and binge eating scale. Predictors of compliance defined as attendance >70 per cent of group sessions were analysed by logistic regression. Results: In both interventions, significant improvements in body mass index, waist circumference and HDL-cholesterol levels were observed. After 9 months, only the individuals submitted to II had blood pressure and plasma glucose levels reduced. The same individuals had significant increases in almost all domains and summary measures of the SF-36. Comparing the induced increases in QoL, measures were greater in the domains of physical functioning...
