The validity and 4-year test-retest reliability of the Brazilian version of the Eating Attitudes Test-26

In a cross-sectional study conducted four years ago to assess the validity of the Brazilian version of the Eating Attitudes Test-26 (EAT-26) for the identification of abnormal eating behaviors in a population of young females in Southern Brazil, 56 women presented abnormal eating behavior as indicated by the EAT-26 and the Edinburgh Bulimic Investigation Test. They were each matched for age and neighborhood to two normal controls (N = 112) and were re-assessed four years later with the two screening questionnaires plus the Composite International Diagnostic Interview (CIDI). The EAT results were then compared to diagnoses originating from the CIDI. To evaluate the temporal stability of the two screening questionnaires, a test-retest design was applied to estimate kappa coefficients for individual items. Given the prevalence of eating disorders of 6.2%, the CIDI psychiatry interview was applied to 161 women. Of these, 0.6% exhibited anorexia nervosa and 5.6%, bulimia nervosa (10 positive cases). The validity coefficients of the EAT were: 40% sensitivity, 84% specificity, and 14% positive predictive value. Cronbachs coefficient was 0.75. For each EAT item, the kappa index was not higher than 0.344 and the correlation coefficient was lower than 0.488. We conclude that the EAT-26 exhibited low validity coefficients for sensitivity and positive predictive value, and showed a poor temporal stability. It is reasonable to assume that these results were not influenced by the low prevalence of eating disorders in the community. Thus, the results cast doubts on the ability of the EAT-26 test to identify cases of abnormal eating behaviors in this population.

Inappropriate Eating Behaviors During Pregnancy: Prevalence and Associated Factors among Pregnant Women Attending Primary Care in Southern Brazil

OBJECTIVE To examine the prevalence of inappropriate eating behaviors and associated factors among pregnant women in primary care. METHOD The Eating Disorder Examination Questionnaire was used to assess eating disorders and the Primary Care Evaluation of Mental Disorders was used to examine anxiety and depressive symptoms. Body mass index (BMI) and pregestational weight were also assessed. RESULTS Prevalence of binge eating during pregnancy was 17.3% [95% confidence interval (CI) 14.5-20.0], followed by excessive shape (5.6%; 95% CI 4-8) and weight concerns (5.5%; 95% CI 4-8). Binge eating during pregnancy was significantly associated with binge eating before pregnancy [prevalence ratio (PR) = 3.1; 95% CI 2.2-4.3], current anxiety symptoms (PR = 1.8; 95% CI 1.3-2.4), and prepregnancy BMI < 19.8 kg/m(2) (PR = 1.6; 95% CI 1.1-2.5). The prevalence of eating disorders was 0.6% (95% CI 0.01-1.11). DISCUSSION Eating disorder symptoms should be routinely assessed and treated during prenatal care, along with other comorbid psychiatric symptoms such as anxiety.

Health-related quality of life in Brazil: normative data for the SF-36 in a general population sample in the south of the country

The objective of this study was to provide normative SF-36 scores in a general population sample in Brazil and to describe differences in mean scores according to socio-demographic characteristics. The SF-36 questionnaire was distributed to a randomly selected sample of the general population of Porto Alegre in the State of Rio Grande do Sul. The response rate was 68% and 755 subjects were included (38% male, 62% female). Lower health status was revealed among females in the 30 to 44 year age bracket, from the lower income class, with less education and self-reported chronic medical conditions. The results and percentiles of scores of the SF-36 are reported as normative data for the general population. The SF-36 was an acceptable and practical instrument for measuring health-related quality of life in a sample of Brazilians. The results of this study can be useful for researchers using the SF-36 questionnaire in other groups to compare the scores with normative data. The SF-36 may prove a valuable tool for discovering vulnerable groups in epidemiological studies due to the ability to discriminate between different population subgroups.

Estimating the SF-6D Value Set for a Population-Based Sample of Brazilians

OBJECTIVES SF-6D is a preference-based measure of health developed to estimate utility values from the SF-36. The aim of this study was to estimate a weighting system for the SF-6D health states representing the preferences of a sample of the Southern Brazilian general population. METHODS A sample of 248 health states defined by the SF-6D was valued by a sample of the southern Brazilian population using the standard gamble. Mean and individual level multivariate regression models were fitted to the standard gamble valuation data to estimate preference weights for all SF-6D health states. The models were compared with those estimated in the UK study. RESULTS Five hundred twenty-eight participants were interviewed, but 58 (11%) were excluded for failing to value the worst state. Data from 469 subjects producing 2696 health states valuations were used in the regression analysis. In contrast to the best performing model for the UK data, the best performing model for the Brazilian data was a random effects model using only the main effects variables, highlighting the importance of adopting a country-specific algorithm to derive SF-6D health states values. Inconsistent coefficients were merged to produce the final recommended model, which has all significant coefficients and a mean absolute difference between observed and predicted standard gamble values of 0.07. CONCLUSIONS The results provide the first population-based value set for Brazil for SF-6D health states, making it possible to generate quality-adjusted life years for cost-utility studies using regional data. Besides, utility weights derived using the preferences of a sample from a southern Brazilian population can be derived from existing SF-36 data sets.

Intensive practical lifestyle intervention improves endothelial function in metabolic syndrome independent of weight loss: a randomized controlled trial

The objective was to evaluate the metabolic and vascular effects of lifestyle interventions involving a healthy diet and either a moderate- or a high-intensity exercise regimen in nondiabetic subjects with metabolic syndrome. The effects of these interventions on flow-mediated vasodilation (FMD) and risk profiles were compared with a standard low-fat diet and engaging in daily walking (standard of care). Seventy-five healthy adults with metabolic syndrome (30-55 years old) were randomized to a 10,000-steps-a-day exercise program, a 3-times-a-week fitness (>75% peak VO(2)) program, or a 1-hour-walking-a-day program for 12 weeks. The first 2 interventions were combined with an accessible healthy, no-sugar diet; and the third was combined with a tailored low-fat diet. The outcomes, including FMD and risk factors, were examined at 12 weeks and at 1-year reassessment. Significant increase in FMD (mean difference = 1.51%, 95% confidence interval = 1.05%-3.017%, P = .0007) and decrease in arterial pressure (mean difference = 19.3 ± 2.3/-12.6 ± 1.8 mm Hg, P = .0001) were observed in all groups. However, the FMD changed most favorably in the high-intensity, low-sugar group (mean difference = 1.56%, 95% confidence interval = 0.1%-3.02%, P = .036). Significant improvements in body mass index, waist, insulin-like growth factor-1, homeostasis model assessment of insulin resistance, insulin, glucose, urinary albumin excretion, and lipid profiles occurred in all groups. Metabolic syndrome was resolved in 64%. One year later, weight loss (-9.1 ± 2.3 kg, P = .0001) and arterial pressure decrease (-18.5 ± 2.3/-12.3 ± 2.1 mm Hg, P = .0001) were maintained. Practical, health-centered diet combined with high-intensity exercise is associated with enhanced vascular protection. These data suggest that more intense exercise combined with a low-sugar diet modulates endothelium-dependent vasodilation.

A Cohort Study to Assess the Impact of Depression on Patients with Kidney Disease

Aims: This study assessed the impact of depression on mortality and quality of life of patients with kidney disease. Material: This study was conducted at Hospital São Lucas of Pontificia Universidade Católica of Rio Grande do Sul, Porto Alegre, Brazil, with a cohort of 125 patients seen from 1996 to 2004 (mean follow-up=77.6 months). Patients undergoing renal replacement therapy were asked to fill in the Beck Depression Inventory (BDI). At the completion of follow-up, 72 patients were alive, and 56 answered the BDI and the Medical Outcome Study Short Form General Health Survey (SF-36) to assess quality of life. Main outcome measures were mortality and quality of life. Results: Initial analysis showed that mortality was associated with age, treatment modality—continuous ambulatory peritoneal dialysis (CAPD) or hemodialysis (hd)—and depression. When controlling for age, gender, depression, and treatment modality in a multiple regression analysis, transplantation (tx), gender and age was associated with lower mortality. However, levels of depression at the end of follow-up were strongly associated with quality of life. Conclusions: Depression was not associated with mortality of patients with kidney disease when controlling for gender, age, and treatment modality. Transplantation was the main factor associated with lower mortality. Depression was, however, a strong predictor of quality of life. Number of depressive symptoms was directly associated with lower quality of life in most of the items of the SF-36.

Nutrition, mental health and violence: from pregnancy to postpartum Cohort of women attending primary care units in Southern Brazil - ECCAGE study

BackgroundWomans nutritional status, before and during pregnancy, is a strong determinant of health outcomes in the mother and newborn. Gestational weight gain and postpartum weight retention increases risk of overweight or obesity in the future and they depend on the pregestational nutritional status and on food consumption and eating behavior during pregnancy. Eating behavior during pregnancy may be the cause or consequence of mood changes during pregnancy, especially depression, which increases likelihood of postpartum depression. In Brazil, a study carried out in the immediate postpartum period found that one in three women experienced some type of violence during pregnancy. Violence and depression are strongly associated and both exposures during pregnancy are associated with increased maternal stress and subsequent harm to the infant. The main objectives of this study are: to identify food intake and eating behaviors patterns; to estimate the prevalence of common mental disorders and the experience of violence during and after pregnancy; and to estimate the association between these exposures and infants health and development.Methods/DesignThis is a cohort study of 780 pregnant women receiving care in 18 primary care units in two cities in Southern Brazil. Pregnant women were first evaluated between the 16th and 36th week of pregnancy at a prenatal visit. Follow-up included immediate postpartum assessment and around the fifth month postpartum. Information was obtained on sociodemographic characteristics, living circumstances, food intake, eating behaviors, mental health and exposure to violence, and on infants development and anthropometrics measurements.DiscussionThis project will bring relevant information for a better understanding of the relationship between exposures during pregnancy and how they might affect child development, which can be useful for a better planning of health actions aiming to enhance available resources in primary health care.

Clustering of risk factors for cardiovascular disease among women in southern Brazil : a population-based study

The association between clustering of risk factors and self-reported cardiovascular disease among women was investigated in a cross-sectional study using a multistage population-based sample. Participants were interviewed at home about diabetes mellitus, physical activity, and diet pattern. Hypertension was defined as blood pressure > or =140/90mmHg or use of anti-hypertensive medication. Cardiovascular disease included self-reported myocardial infarction, heart failure, coronary artery bypass surgery, and stroke. A sample of 1,007 women from Porto Alegre, Southern Brazil, mostly white (73%), 44.8 +/- 0.8 years old, and with 9.3 +/- 0.3 years of schooling was investigated. Hypertension, diabetes mellitus, obesity, low fruit and vegetable intake, and lack of vigorous or moderate physical activity were clustered into a combination of risk factors, which were independently associated with self-reported cardiovascular disease. The main cluster included hypertension and diabetes, accounting for an independent risk ratio of 8.5 (95%CI: 3.0-24.5). Clustering of cardiovascular risk factors is strongly associated with self-reported cardiovascular disease among women.

Validação relativa de Questionário de Freqüência Alimentar em gestantes usuárias de serviços do Sistema Único de Saúde em dois municípios no Rio Grande do Sul, Brasil

OBJECTIVES: to evaluate a Food Frequency Questionnaire (FFQ) previously designed by Sichieri and Everhart to provide information about food consumption among pregnant women attended by the Brazilian National Health Service. To compare the mean daily intakes of energy and nutrients as assessed using a FFQ and dietary recalls. METHODS: the study took place in two cities: Bento Goncalves and Porto Alegre, State of Rio Grande do Sul, Brazil. During a first interview, the FFQ was administered to pregnant women, followed by two dietary recalls. In a second interview two further food recalls were obtained. The Bland-Altman analysis was used to assess the degree of agreement between the FFQ and dietary recalls. RESULTS: the FFQ produced higher energy and nutrient intakes. The correlation coefficient between nutrient intake measured using dietary recalls and using the questionnaire, after adjusting for energy intake, ranged from 0.1 (unsaturated fat) to 0.47 (calcium). The nutrients: fiber, Vitamin C, folate, calcium and potassium showed higher coefficients (above 0.4). Thirty percent of individuals were classified by the two dietary assessment methods into the same quartile. CONCLUSION: this FFQ is a useful tool for epidemiological studies among pregnant women; although efforts need to be made to improve its performance. More studies are necessary to identify sociocultural and behavioural factors that influence its validity.

Violence during pregnancy and newborn outcomes: a cohort study in a disadvantaged population in Brazil.

BACKGROUND Violence against pregnant women is an increasing public health concern. The purpose of this study is to estimate the prevalence of violence during pregnancy, to identify characteristics associated and to assess the impact of violence on newborn outcomes. METHODS Prospective cohort study of 652 pregnant women attending primary care clinics in Southern Brazil, from June 2006 to September 2007. Women with gestational age ranging from 16th and 36th were enrolled and their exposure to violence and mental disorder was assessed. After the birth they were contacted by telephone when information on obstetric and neonatal outcomes was obtained. RESULTS Any violence during current pregnancy was reported by 18.3% [95% confidence interval (CI) 15.3-21.4%] participants, 15.0% (95% CI 12.3-17.8%) psychological violence, 6% (95% CI 4.2-7.8%) physical violence and 3% (0-0.5%) sexual violence. These women were more often of low income, did not work or study and had inadequate prenatal care and pregnancy weight gain. There was a statistically significant crude association between exposure to physical and psychological violence [relative risk (RR) 3.21 (1.51-6.80)]. After adjustment for family income, number of prenatal visits, length of gestation and gestational weight gain, the effect size decreased, but remained statistically significant (RR 2.18; 95% CI 1.16-4.08%). CONCLUSION In disadvantaged settings in Brazil, violence in pregnancy is frequent; it is associated with inadequate maternal weight gain during pregnancy and prenatal care, and increases risk of low birth-weight. Thus, violence in pregnancy imposes a challenge to effective prenatal care delivery with potential benefits to the mother and her baby.
