Variáveis antropométricas e hemodinâmicas em relação a diferentes níveis e categorias de atividade física

This study aimed to investigate the relation between physical activity levels (PAL) of hypertensive patients, seeing different do- mains, and, to compare anthropometric variables and blood pressure (BP). The survey was conducted with 192 patients, mean age 63 ± 11 years. The anthropometric variables were body weight, body mass index (BMI) and waist circumference (WC). PAL was estimated using Baecke ́s questionnaire and categorized in four domains (OPA = occupational; leisure time = LTPA; locomotion = LPA and Total PA). Student t test unpaired was applied for comparisons between active and insufficiently active. Differences between active and sedentary in relation to anthropometry and resting blood pressure were observed for the LTPA, LPA and Total PA and significant negative correlations were observed between LPA and Total PA with systolic BP (p<0,05). Conclusion: the LPA and LTPA were associated with resting BP in hypertensive. No differences in BMI and WC among physically active and insuffi- ciently active were found.

Impacto de diferentes métodos de avaliação da obesidade abdominal após síndromes coronarianas agudas

Background: Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC) is a priority. Objective: To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS) as a predictor of cardiovascular complications during hospitalization. Methods: Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1), point of minimum circumference (2); immediately above the iliac crest (3), umbilicus (4), one inch above the umbilicus (5), one centimeter above the umbilicus (6), smallest rib and (7) the point of greatest circumference around the waist (8). Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. Results: A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67%) patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. Conclusion: The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes. Key words: Evaluation; Acute Coronary Syndrome; Abdominal Circumference

Indeterminate form of chagas disease and metabolic syndrome: a dangerous combination

Chagas’ disease (CD) has been a major concern in public health in Latin America countries and in Brazil there are about 3 million people suffering from this disease. With the social and economic changes which have been occurring in the last 6 decades in the country, there have been a lot of changes in the population life style with severe metabolic consequences, especially for those with Chagas' disease. The objective of this study was to evaluate the prevalence of metabolic syndrome in individuals with the indeterminate form of CD. A total of 74 individuals, mean age of 55.6 years, participated in the study. Anthropometric and biochemical evaluations were performed. Overweight/obesity was found in 86.5 % of individuals, increased waist circumference in 72.5%, and 67% had more than 30% of fat mass. Hyperglycemia and dyslipidemia were observed in 24.3% and 75.7% of patients, respectively. Metabolic syndrome was diagnosed in 48.2% of patients. The family history revealed high prevalence of cardiovascular diseases (80.3%), systemic arterial hypertension (57.1%) and diabetes mellitus (42.8%). A total of 90% of patients were overweight/obese, and it is well known that increased adipose tissue, specially visceral adipose tissue is highly associated with dyslipidemia and cardiovascular diseases, as well as imbalance in production of proinflammatory and antiinflammatory cytokines produced by that tissue. Adipocytes are also known as a reservoir for Trypanosoma cruzi, favoring an increase in parasite load and a possible reacutization of the disease. Therefore, the study individuals are at high risk of developing cardiovascular diseases as well as further symptomatic form of the Chagas' disease, mainlychagastic cardiopathy.

Association of fat intake and socioeconomic status on anthropometric measurements of adults

We aimed to identify the influence of dietary fat profile on body mass index (BMI) and waist circumference (WC) in a middleclass general population sample. A cross-sectional study of 448 adults aged 35-85 years was carried out from January 2004 to December 2007. Patients were divided in two groups according to family income: Group 1 (G1) with higher income, and Group 2 (G2) with lower income. Demographic and socioeconomic status were identified, along with anthropometric data, health eating index (HEI) and dietary profile. The groups were similar with respect to gender, age, BMI and WC. HEI was higher in G1 due to a higher intake of protein (+12.8%), dairy products (p<0.001), higher intake of vegetables (p<0.01), fruit (p<0.001), and less dietary fat (-9.8%). The main contribution of fats was saturated fat for G1 (+5.0%) and polyunsaturated fat for G2 (+14.4%). Besides differences in socioeconomic status the groups had similar BMI and abdominal fatness. Only differences in fat profile were correlated with the anthropometric measures mostly explained by the lower vegetable oil intake in higher income participants.

Improvements of nutrition behavior fitness and body fatness with a short-term after school intervention program

The prevalence of childhood obesity has been increasing worldwide and lifestyle changes are the most important strategies in managing this prevalence. This study aimed to describe the intervention effects of nutrition and physical activities offered as an after school short-term on outcomes of healthy nutrition practices, fitness and lowering fatness. This quasi-experimental study was conducted with a convenience sample of 59 caucasian children, aged 7.7 ± 1.4 years old (52.5% girls) registered on a private school of a middle-size town located in Sao Paulo State, Brazil. The school-based 12-week intervention consisted of 2 weekly 60 minutes section, during 3 months, including a nutritional education and a physical activity curriculum. Anthropometric data was measured for all children at baseline and after 12 weeks. All parents were contacted and requested to complete questionnaire about child’s eating behavior at baseline and after the 12-week program. After the intervention, children showed an increasing in the intake of fruits (64.3%), vegetables (61.9%), and water (52.0%). Overall, 83.3% of the children changed eating behavior according to the questionnaire responded by the parents. Waist circumference was significantly lower and abdominal strength improved after participating in the intervention program. Mean height and weight were significantly higher in boys and girls after a 12-week intervention. Although mean values of BMI remained the same after the intervention it was observed a decreasing in the prevalence of obesity among the children. Thus our study showed that a school-based intervention program focused on nutritional education and physical activity program promoted waist circumference reduction and decreased obesity without affecting the height growth along with improved fitness and healthy eating behavior. This intervention program would be feasible and replicable in others schools around the country.

Omega-3 fatty acids supplementation decreases metabolic syndrome prevalence after lifestyle modification program

The additional effect of omega-3 supplementation in association with lifestyle modification program (LSMP) in free living-adults was evaluated.We studied 39 adults (control group with LSMP (G1, n = 16) and LSMP plus supplementation of 3 g of fish oil per day (360 mg of docosahexaenoic acid and 540 mg of eicosapentaenoic acid) (G2, n = 23)) during 20 weeks. The fish oil group showed a significant decrease in waist circumference (1.3%) followed by metabolic syndrome reduction (29%) mainly due to normalization of blood pressure (33.3%) and triacylglycerol (27.3%). Omega-3 supplementation provided additional benefits to LSMP in the resolution of metabolic syndrome

Estado nutricional e ocorrência de hipertensão arterial e de diabetes em idosos residentes e não residentes em instituições geriátricas

The aging process involves challenges in meeting social needs, economic and health. Physiopathological changes and socio-economic predispose the elderly population at nutritional risk. The monitoring of nutritional status predict some complications of obesity or malnutrition, and is a tool for health care. The objective to know the nutritional status and risk of chronic diseases of the elderly in geriatric institutions and volunteers. The elderly population of 3 geriatric institutions (n=122) and non-institutionalized elderly (n=75) were evaluated. The body mass index was evaluated according to Nutrition Screening Initiative. For waist circumference, was used the World Health Organization criteria. For statistical analysis, chi-square was used. A high proportion of obesity (46%) was observed. The underweight affects 4% and 20% of noninstitutionalized and institutionalized, respectively. The frequency of the risk of diseases associated with obesity was higher among non-institutionalized. Hypertension affects more than 50% of the elderly. The nutritional status was different between the two situations, with high incidence of overweight and visceral adiposity, in volunteers, and wasting among institutionalized. The data emphasize that it is necessary special attention and appropriate measures to prevent morbidity and mortality and to improve quality of life.
