RESUMEN
BACKGROUND: Prevalence of individuals with a high cardiovascular risk is elevated in elderly populations. Although metabolic syndrome (MS) increases cardiovascular risk, information is scarce on the prevalence of MS in the elderly. In this study we assessed MS prevalence in a population of elderly Japanese-Brazilians using different MS definitions according to waist circumference cutoff values. MATERIAL/METHODS: We studied 339 elderly subjects, 44.8% males, aged between 60 to 88 years (70.1 ± 6.8). MS was defined according to criteria proposed by the Joint Interim Statement in 2009. As waist circumference cutoff point values remain controversial for Asian and Japanese populations, we employed 3 different cutoffs that are commonly used in Japanese epidemiological studies: 1) ≥ 90 cm for men and ≥ 80 cm for women; 2) ≥ 85 cm for men and ≥ 90 cm for women; 3) ≥ 85 cm for men and ≥ 80 cm for women. RESULTS: MS prevalence ranged from 59.9% to 65.8% according to the different definitions. We observed 90% concordance and no statistical difference (p>0.05) in MS prevalence between the 3 definitions. MS diagnosis according to all 3 cutoff values was found in 55.8% of our population, while in only 34.2% was MS discarded by all cutoffs. The prevalence of altered MS components was as follows: arterial blood pressure 82%, fasting glycemia 65.8%, triglyceride 43.4%, and HDL-C levels 36.9%. CONCLUSIONS: Elderly Japanese-Brazilians present high metabolic syndrome prevalence independent of waist circumference cutoff values. Concordance between the 3 definitions is high, suggesting that all 3 cutoff values yield similar metabolic syndrome prevalence values in this population.

OBJECTIVE: To describe the results of a nutritional intervention programme among Japanese-Brazilians according to gender. DESIGN: A non-controlled experimental study. SETTING: The research included three points of clinical, nutritional and physical activity evaluation: at baseline (in 2005), after the first year and at the end of the second year (in 2007). The paired Student t test and multiple linear regression analysis were used to evaluate changes in the subjects' profile (clinical, nutritional and physical activity variables). SUBJECTS: Japanese-Brazilians (n 575) of both genders, aged over 30 years. RESULTS: We verified statistically significant reductions in body weight (0.9 kg), waist circumference (2.9 cm), blood pressure, fasting blood glucose (>3 mg/dl) and total cholesterol (>20 mg/dl) and its fractions, in both genders. We also found reductions in intake of energy (among men), protein (among women) and fat (both genders) and increases in intake of total fibre (among women) and carbohydrate (among men). CONCLUSIONS: The intervention programme indicated meaningful benefits for the intervention subjects, with changes in their habits that led to a 'healthier' lifestyle positively impacting their nutritional and metabolic profile.

The purpose of this study is to determine the correlation of socioeconomic, dietary, and anthropometric-nutritional variables of parents and their children to overweight (including obesity) in schoolchildren in Santa Catarina State, Brazil. This is a transversal study conducted on 4,964, 6 to 10-year-old schoolchildren registered in 345 Santa Catarina elementary schools. The following data were acquired: the children's current weight and height, birth weight and length, duration of breastfeeding, age at which water, herbal tea and other foods were introduced to their diet; parental income, education level, age, weight and height were also obtained. The prevalence of overweight and obese children were estimated by point and by interval with a 95% confidence; prevalence rates were obtained based on the Poisson model. An hierarchical approach was used, in which variables were adjusted within blocks and included in the model when they presented p < 0.05 at the outcome (overweight including obesity). The results indicate that 47.8% of the subjects were male. The prevalence of overweight and obese students was 15.4% (C195%: 14.4%-16.5%) and 6.1% (C195%: 5.4%-6.7%) respectively and were statistically similar among sexes and age ranges. BMI values were higher in males and among older children (p < 0.05). After adjustment within and among blocks, the variables per capita household income and parents' BMI values remained associated with overweight (including obesity). Overweight (including obesity) in schoolchildren is associated with a higher per capita household income and parental overweight and obesity.

OBJECTIVE: To determine the agreement between body self-image (based on the Stunkard figure rating scale) and nutritional status and to evaluate body satisfaction among the Khisêdjê indigenous people of Parque Indígena do Xingu (Xingu Indigenous Park). METHODS: A cross-sectional study involving 131 natives aged 20 and older. Data on body image, body mass index and waist circumference were collected. Kappa statistics, χ2 (p < 0.05), crude and adjusted prevalence ratios and Student's t-test were used for data analysis. RESULTS: The prevalence of overweight and obesity was respectively 42 and 5.3%. The percentage of satisfaction with body profile was 61.8% with no difference between the sexes. There was good agreement between actual and ideal self-image (p < 0.001), but poor agreement between actual and ideal self-image with nutritional status for both sexes. A higher prevalence of body dissatisfaction due to overweight was detected in individuals with central obesity and overweight. CONCLUSION: The results suggest that body self-image evaluated by the Stunkard silhouette scale has little applicability as an indicator of nutritional status among the indigenous Khisêdjê of Xingu Indigenous Park.

The aim of this study was to describe metabolic changes in HIV/AIDS patients according to the treatment regimen. It was a retrospective cohort conducted from 2002 to 2014. Researchers surveyed clinical variables and treatment regimen of 538 individuals. They used measures of central tendency and marginal logistic regression to determine the influence of the treatment regimen on clinical variables over time; survival was estimated using Kaplan-Meier curves. 56.2% of patients were male, 82.2% white, 33.8% had 4 to 7 years of study, 49.2% were married, 98.5% had sexual transmission, and 89.0% were heterosexuals. During the study period, 24.4% had hypertension, 18.2% changed cholesterol, 39.7% low HDL, 51.3% high triglycerides and 33.3% hyperglycemia. Treatment regimens with nucleotide reverse transcriptase inhibitors associated with protease inhibitors, and the association of different classes of antiretrovirals have been associated with greater lipid changes. Higher metabolic changes were observed in patients with longer treatment time. It is concluded that preventive measures, as well as early treatment, can contribute to minimize the risks of developing cardiovascular diseases.

BACKGROUND: Mindfulness has been applied in the United States and Europe to improve physical and psychological health; however, little is known about its feasibility and efficacy in a Brazilian population. Mindfulness may also be relevant in tackling obesity and eating disorders by decreasing binge eating episodes-partly responsible for weight regain for a large number of people-and increasing awareness of emotional and other triggers for overeating. The aim of the present study protocol is to evaluate and compare the feasibility and efficacy of two mindfulness-based interventions (MBIs) addressing overweight and obesity in primary care patients: a general programme called Mindfulness-Based Health Promotion and a targeted mindful eating protocol called Mindfulness-Based Eating Awareness Training. METHODS/DESIGN: A randomised controlled trial will be conducted to compare treatment as usual separately in primary care with both programmes (health promotion and mindful eating) added to treatment as usual. Two hundred forty adult women with overweight and obesity will be enrolled. The primary outcome will be an assessment of improvement in eating behaviour. Secondary outcomes will be (1) biochemical control; (2) anthropometric parameters, body composition, dietary intake and basal metabolism; and (3) levels of mindfulness, stress, depression, self-compassion and anxiety. At the end of each intervention, a focus group will be held to assess the programme's impact on the participants' lives, diet and health. A feasibility study on access to benefits from and importance of MBIs at primary care facilities will be conducted among primary care health care professionals and participants. Monthly maintenance sessions lasting at least 1 hour will be offered, according to each protocol, during the 3-month follow-up periods. DISCUSSION: This clinical trial will result in more effective mindfulness-based interventions as a complementary treatment in primary care for people with overweight and obesity. If the findings of this study confirm the effectiveness of mindfulness programmes in this population, it will be possible to improve quality of life and health while optimising public resources and reaching a greater number of people. In addition, on the basis of the evaluation of the feasibility of implementing this intervention in primary care facilities, we expect to be able to suggest the intervention for incorporation into public policy. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02893150 . Registered retrospectively on 30 March 2017.

The aim of this study was to verify the association between nutritional variables and mortality in a Japanese-Brazilian cohort. In 1993, 647 subjects were interviewed with food frequency questionnaires and scheduled for physical procedures (weight, height, blood pressure) and biochemical tests (oral glucose tolerance test). Student's t test was used to compare the mean values of target variables between living and deceased subjects. Mortality rate and hazard ratios were obtained (crude and adjusted) according to the nutritional variables. Overall mortality rates were 21.4 and 11.7/1,000 person-years for males and females, respectively. Smoking, diabetes, sedentary lifestyle, hypertension, higher mean age, high blood pressure, high blood glucose, and higher percent weight gain and rate of weight gain were observed in the history of deceased subjects. After adjusting for control variables, an increase was observed in mortality among individuals with lower carbohydrate and cholesterol intake. The results suggest that mortality risk factors like age, chronic diseases, sedentary lifestyle, smoking, and inadequate diet must also be acting in the Japanese-Brazilian population.

This cross-sectional study focused on the relationship between periodontal disease and metabolic syndrome. Data were analyzed from 1,315 Japanese-Brazilians ranging from 30 to 92 years of age, submitted to physical, laboratory, and dental exams. Means and percentages were used in the data description and logistic regression pattern in the analysis of associations among variables. 484 (36.8%) of the 1,315 were edentulous, 215 (16.4%) enjoyed periodontal health, 513 (39%) had gingivitis, 85 (6.5%), showed initial or moderate periodontitis, and 18 (1.4%) suffered from chronic periodontitis. Prevalence of metabolic syndrome was 54.3%, higher among individuals with periodontitis than in the healthy (51.5% vs. 48.8%), but this association was not statistically significant. Individuals with metabolic syndrome showed a worse metabolic and anthropometric profile.

The objective of this study was to evaluate the impact of different body mass index (BMI) ranges associated with the risk of diabetes and hypertension in Japanese-Brazilians. This cross-sectional study was based on data from 1,330 Japanese-Brazilians > 30 years of age who participated in a population-based survey on the prevalence of diabetes mellitus and associated diseases. Glucose tolerance status was classified according to WHO criteria and blood pressure levels according to the VI-JNC. Odds ratios for diabetes and hypertension were calculated for different BMI ranges; for different BMIs, sensitivity and specificity for percentiles 25, 50, 75, 90 and 95 were obtained. Increased odds ratios for diabetes mellitus and hypertension were observed with BMI values > 25 kg/m(2). The 50th percentile corresponded to the highest sensitivity and specificity for the identification of risk for both diseases. Our results suggest that BMI values proposed by WHO should also be useful for this group of Japanese descendants in the assessment of risk for DM and hypertension.

To examine dietary intakes in relation to long-term serum lipoprotein changes in a prospective cohort study with 7 y of follow-up, serum lipids were analyzed by enzymatic methods, while food intake was calculated from validated food frequency questionnaires. First- and second-generation Japanese-Brazilians (n = 316) living in Bauru, São Paulo/Brazil, of both genders, aged 40 to 79 y were assessed at baseline in 1993. Multiple linear regression models were used with changes in serum lipoproteins as the dependent variable and changes in dietary intakes as the independent variables, adjusted for confounding factors. In energy-adjusted analyses, changes in serum total cholesterol were inversely associated with changes in total dietary fiber, fruits/fruit juices and vegetables after adjustment for age and gender. Each increase of 10 g in the consumption of total dietary fiber was associated with a reduction of 12.5 mg/dL in the serum total cholesterol (p<0.05). Our results highlight the importance of increased intakes of total fiber, fruits and vegetables to prevent and control dyslipidemia in Japanese migrants.

Cross-sectional surveys were performed in 1993 and 2000 on Japanese-Brazilians (n = 328) of both sexes, aged 40 to 79 years in 1993, living in Bauru, São Paulo State. Both surveys examined food intake using food frequency questionnaires. Dietary intake in both surveys was compared to Wilcoxon tests according to gender (p < 0.05). Calories from dietary fat increased by 16% in both genders (mean values in 2000: 31.5% for women and 30.8% for men). When the surveys were compared, the main dietary changes were: (a) a 40% increase in oleic and linoleic acids and calories from fat and (b) a 20% reduction in dietary cholesterol in both sexes. Among women, an increase in total calorie intake with reduced consumption of vegetables and calories from sweets were observed. Despite increased intake of total dietary fat, there was a decrease in cholesterol intake and an increase in oleic and linoleic acids, fruit, and calcium. However, calcium and vegetable consumption is still short of international recommendations.

The current article aimed to verify the degree of agreement in classification of nutritional status according to body mass index (BMI) and corrected body mass index (BMIc). Data were used from a cross-sectional study of Japanese-Brazilians. Statistical analysis provided prevalence rates for chronic diseases, kappa statistic, and Pearson's linear correlation coefficient. Some 5.9% of Japanese-Brazilians were discordant according to the BMI and BMIc classifications. The weighted kappa statistic (0.94; p = 0.000) indicated good agreement between the classifications. Similar prevalence rates for chronic diseases were obtained for individuals with excess weight classified by these two indices. Similar Pearson's linear correlation coefficients were obtained for these indices and waist circumference and body fat measurements. The results suggest that BMI correction for relative sitting height is probably unnecessary for these individuals.

OBJECTIVE: Vertebral fracture is the most common osteoporotic fracture, affecting quality of life and increasing mortality. Epidemiological data on incidence of vertebral fracture are scarce in Brazil and throughout Latin America. Our aim was to determine vertebral fracture incidence and risk factors in a female Brazilian population. SUBJECTS AND METHODS: Postmenopausal women with low bone mass were studied from the Brazilian placebo group of Arzoxifene Generations Trial (n = 974), followed for up to 5 years. The primary endpoint was new vertebral fractures, detected by X-Ray. Experimental design defined two strata: A. Osteoporosis or previous vertebral fracture with osteopenia; B. Osteopenia without previous fracture. Previous fracture, T-score, ionized calcium, alkaline phosphatase, creatinine and glucose were analyzed at baseline. Crude and adjusted incidence rates of vertebral fractures were estimated and Poisson regression model was used. RESULTS: Incidence rate was 7.7 (95% CI of 5.4 to 10.9) per 1,000 person-years (PY), increasing as a function of age. Women with new vertebral fractures had higher prevalence of previous nonvertebral fracture after menopause, were older and had lower lumbar spine (LS) T-score. Fracture risk increased by 46% for each unit reduction in LS T-score. Variables correlated with new vertebral fracture were age (p = 0.034), LS T-score, stratum A (p = 0.001 for both) and previous nonvertebral fracture after menopause (p = 0.019). In the final model, LS T-score was the strongest predictor. CONCLUSIONS: Incidence rate of vertebral fracture of 7.7 per 1,000 PY. Age and previous fractures were associated with new vertebral fracture, but LS T-score was the most important predictor.

The objective of the Food and Nutrition Surveillance System (SISVAN) is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS). The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS), using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program) associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household) associated with breast milk consumption (p = 0.048). The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

RESUMO: Objetivos: Verificar a concordância entre autoimagem corporal (escala de silhuetas de Stunkard et al.) e estado nutricional e avaliar a satisfação corporal em indígenas khisêdjê do Parque Indígena do Xingu. Métodos: Estudo transversal que incluiu 131 indígenas khisêdjê, com 20 anos ou mais. Coletaram-se dados sobre imagem corporal, índice de massa corporal e perímetro da cintura. Foram utilizados a estatística kappa, o teste χ2 (p < 0,05), as razões de prevalências brutas e ajustadas e o teste t de Student. Resultados: As prevalências de sobrepeso e obesidade foram, respectivamente, 42 e 5,3%. A porcentagem de satisfação com o perfil corporal foi de 61,8%, sem diferença entre os sexos. Houve boa concordância entre autoimagem real e autoimagem ideal (p < 0,001), porém baixa concordância entre a autoimagem real e ideal e o estado nutricional para ambos os sexos. Maior prevalência de insatisfação corporal por excesso de peso foi detectada entre indivíduos com obesidade central e excesso de peso. Conclusão: Os resultados sugerem que a autoimagem corporal avaliada por meio da escala de silhuetas de Stunkard et al. tem pouca aplicabilidade como indicador do estado nutricional de indígenas khisêdjê do Parque Indígena do Xingu.

This study describes breastfeeding practices with children born in a university hospital in the city of S o Paulo, Brazil, and identifies factors associated with duration of breastfeeding and exclusive breastfeeding. A cohort of 506 children was identified; of these, it was possible to analyze information on feeding practices for 450 infants at least until the second month of life. Daily information on infant feeding was recorded by mothers in a food frequency questionnaire. Survival analysis techniques (Kaplan-Meier and Cox) were used. Median duration of breastfeeding and exclusive breastfeeding were 205 and 23 days, respectively. The principal factors related to exclusive breastfeeding were mother's age (hr young/old = 1.22; 95% CI = 1.006-1.486) and mother's schooling (hr primary/university = 2.13; 95% CI = 1.381-3.307 and hr secondary/university = 1.78; 95% CI = 1.145-2.792), which could be related to knowledge concerning the benefits of exclusive breastfeeding.

OBJECTIVE: Methods to evaluate food consumption still need improvement. A study was conducted to verify the reproducibility and validity of a food frequency questionnaire (FFQ) among overweight adults. METHODS: The study was carried out in a private university in São Paulo, Brazil. The study sample consisted of 146 individuals of both sex with body mass index =25 kg/m2 and age between 18 and 60 years old. For reproducibility the FFQ was applied by trained interviewers at two different instances with a mean interval time of 47 days. For validity, data collected from the FFQ were compared with those obtained from the average of 3 different daily records of a 24-hour dietary recall (mean interval time: 15 days). Validity and reproducibility of data on calories and macronutrients consumption was assessed using pondered kappa statistics and intraclass correlation coefficient. RESULTS: A higher variability in the reporting of regular food consumption was seen among obese than overweight individuals. Concerning reproducibility, kappa statistical values varied from 0.23 (carbohydrates and fats) to 0.40 (calories), and intraclass correlation coefficients ranged from 0.28 (protein) to 0.54 (total calories). For FFQ validity, the highest kappa value was 0.25 (calories), and the intraclass correlation coefficient was 0.21 (protein). CONCLUSIONS: Food consumption reports of overweight individuals tend to be underestimated. Despite its limitations, FFQ could be used in epidemiological studies to assess the regular food consumption of overweight individuals.

Abstract The aim of this study was to describe metabolic changes in HIV/AIDS patients according to the treatment regimen. It was a retrospective cohort conducted from 2002 to 2014. Researchers surveyed clinical variables and treatment regimen of 538 individuals. They used measures of central tendency and marginal logistic regression to determine the influence of the treatment regimen on clinical variables over time; survival was estimated using Kaplan-Meier curves. 56.2% of patients were male, 82.2% white, 33.8% had 4 to 7 years of study, 49.2% were married, 98.5% had sexual transmission, and 89.0% were heterosexuals. During the study period, 24.4% had hypertension, 18.2% changed cholesterol, 39.7% low HDL, 51.3% high triglycerides and 33.3% hyperglycemia. Treatment regimens with nucleotide reverse transcriptase inhibitors associated with protease inhibitors, and the association of different classes of antiretrovirals have been associated with greater lipid changes. Higher metabolic changes were observed in patients with longer treatment time. It is concluded that preventive measures, as well as early treatment, can contribute to minimize the risks of developing cardiovascular diseases.
Resumo O objetivo deste estudo foi descrever os fatores de risco cardiovascular em pacientes HIV/AIDS de acordo com o esquema terapêutico utilizado. Estudo de Coorte retrospectiva no período de 2002 a 2014. Foram levantadas variáveis clínicas e esquema de tratamento de 538 indivíduos. Utilizaram-se medidas de tendência central, e regressão marginal logística para verificar a influência do esquema de tratamento sobre variáveis clinicas ao longo do tempo. Dos pacientes, 56,2% eram homens, 82,2% brancos, 33,8% tinham entre 4 a 7 anos de estudo, 49,2% eram casados, 98,5% tiveram transmissão sexual e 89,0% eram heterossexuais. A idade média no diagnóstico foi de 36,3 anos. Durante o período de estudo, 24,4% hipertensão arterial, 18,2% colesterol alterado, 39,7% HDL baixo, 51,3% triglicerídeos elevados e 33,3% hiperglicemia. Os esquemas de tratamento com Inibidores da transcriptase reversa nucleotídeos associados a inibidores da protease, e a associação de diferentes classes de antirretrovirais estiveram associados a maiores alterações lipídicas e maiores alterações metabólicas com maior tempo de tratamento. Conclui-se que medidas preventivas, bem como tratamento precoce pode contribuir para minimizar os riscos de desenvolvimento de doenças cardiovasculares.

The aim of this study was to analyze the prevalence of cytological atypia and human papillomavirus infection in Panará indigenous women in 2006-2007. This was a cross-sectional observational study with data obtained from vaginal cervical samples for Pap smear and hybrid capture, colposcopy, and biopsy. The study included 86 females 12 years or older with a history of sexual activity. 10.7% of the women were diagnosed with cytological atypia and 28.6% were infected with high-risk HPV genotypes, which were more common among young women (mean = 25.6 years). Of these, 41.7% were positive for high-risk HPV genotypes 16 and/or 18 and/or 45, and the majority (58.3%) for other high-risk HPV genotypes. The study concludes that this group of indigenous women constitutes a special population, susceptible to develop precursor lesions for cervical cancer and vulnerable to STDs. Preventive measures are required, such as systematic cervical cancer screening and HPV immunization.

The aim of this study was to identify the incidence of metabolic syndrome and related diseases in the Khisêdjê population living in the Xingu Indigenous Park, Mato Grosso State, Brazil, from 1999-2000 to 2010-2011. The study included 78 individuals aged ≥20 years. Data were analyzed using Student t test, linear regression, and Poisson regression. In 10 years of follow-up, cumulative incidence rates were 37.5% for metabolic syndrome, 47.4% for hypetriglyceridemia, 38.9% for arterial hypertension, 32% for central obesity, 30.4% for excess weight, 29.1% for hypercholesterolemia, 25% for low HDLc, 10.4% for high LDLc, and 2.9% for diabetes mellitus. Age proved to be a risk factor for incidence of hypertension, diabetes, and elevated LDLc, regardless of gender; male gender was a protective factor against incidence of central obesity, independently of age. The study showed deterioration of most target health indicators and exposure of the Khisêdjê to high cardiometabolic risk. These results may be related to changes in traditional lifestyle.
