Data were collected in personal interviews applying a structured survey which included a food frequency questionnaire and the Brazilian Food Insecurity Scale. Families were classified as “extremely poor”, if per capita family income was under US$1.00 per day or, otherwise, as “out of extreme poverty”. “Extremely poor” families were also stratified as beneficiaries or not of cash transfer programs which were later consolidated within the Programa Bolsa Familia. Overall, the studied families lived under critical sanitary conditions. Families in extreme poverty presented worse conditions of household sanitation, food insecurity and reported poorer food quality, less frequent consumption of fruit and vegetables, and increased use of practic...

Schools are the central focus of interventions aiming the prevention and treatment of childhood obesity, however, randomized trials and cohort studies have not yet provided clear evidence of strategies to reduce prevalence of obesity. The aim of this study is to present a protocol to evaluate the efficacy of combining school and household level interventions to reduce excessive weight gain among students. The intervention target fifth and sixth graders from 18 public schools (9 interventions and 9 controls) in the municipality of Duque de Caxias, metropolitan area of Rio de Janeiro, Brazil. A sample size of 2500 students will be evaluated at school for their weight status and those from the intervention group who are overweight or obese will be followed monthly at home by community health agents. Demographic, socioeconomic, anthropometric, eating behavior and food consump...

A controlled randomized cluster trial was carried out in twenty public schools in the municipality of Niteroi in Rio de Janeiro, Southeastern Brazil, from March to December 2007. A nutrition educational program was implemented in the schools in question through messages, activities and printed educational materials encouraging reduced levels of added sugar in school meals and in the school lunch cooks' own intake. The reduced availability of added sugar in schools was evaluated using spreadsheets including data on the monthly use of food item supplies. The cooks' individual food intake was evaluated by a Food Frequency Questionnaire. Anthropometric measurements were taken according to standardized techniques and variation in weight was measured throughout the duration of the study. There was a more marked reduction in the intervention schools compared to the control schools (-6.0 kg versus 0.34 kg), but no statistically significant difference (p = 0.21), although the study power was low. Both groups of school lunch cooks showed a reduction in the consumption of sweets and sweetened beverages, but the difference in sugar intake was not statistically significant. Weight loss and a reduction in total energy consumption occurred in both groups, but the difference between them was not statistically significant, and there was no alteration in the percentages of adequacy of macronutrients in relation to energy consumption. The strategy of reducing the use and consumption of sugar by school lunch cooks from public schools could not be proved to be effective.

To determine the food sources of energy consumed by Brazilians, we used the traditional method of ranking energy contribution of selected food groups and also compared days with and without consumption of specific food groups. Analysis was based on two non-consecutive days of dietary record from the Brazilian National Dietary Survey, conducted among 34 003 Brazilians (aged 10 years or more), taking into account the complex design of the survey. Comparison of days with and without consumption gave more consistent results, with sweets and cookies as the most important contributors to energy intake, increasing 992 kJ/d (95 % CI 883, 1096) for those days when consumption of cakes, cookies and desserts was reported compared to days without their consumption. Savoury snacks, cheese and sugar-sweetened beverages (SSB) also increase energy intake by about 600 kJ. The only grou...

The study consisted in a clinical trial including 40 obese women (BMI 30.41 to 53.29 kg/m2), 20 in each group. Both groups received nutritional counseling and psychological support. The intervention group participated in supervised exercise three times per week for 20 weeks. For the anthropometric measurements, which were taken at three times, the linear mixed modeling procedure showed a reduction of 2 kg in body mass (p = 0.02) and 0.88 kg/m2 in the Body Mass Index (p = 0.02) in intervention group compared with controls after 20 weeks of treatment. We did not detect significant differences between the two groups for body fat location (waist circumference and waist-to-hip ratio), serum lipoprotein profile, and insulin sensitivity evaluated by HOMA-IR. Serum levels of free fatty acids significantly increased in the in...

Cross-sectional study conducted in Brazil during 2008 and 2009. A 2d dietary record of individuals was used. The usual intake of folic acid by sex and age group was estimated using the National Cancer Institute method. The quantity of folic acid and Fe established by mandatory food fortification in Brazil was used, and based on that quantity we calculated the amount of flour consumed and the intake of Fe from fortification and Fe from food. Then, the absorption of each nutrient was calculated. Brazilian households (n 16 764). Individuals (men and women, n 34 003, aged 10 to 60+ years) from a Brazilian nationwide survey. Mean intake and absorption of Fe from fortification (electrolytic Fe) was low in men and women. The impact from the consumption of fortified products is small in relation to Fe intake in Brazil....

A cross-sectional study with adolescents aged 10 to 17 years, of both sexes, belonging to a 1994-1999 birth cohort in the city of Cuiabá, MT, Central Western Brazil. Data were collected using a questionnaire containing sociodemographic, economic, lifestyle and anthropometric variables. Sedentary behavior was determined as using television and/or computer/video games for a time greater than or equal to 4 hours/day. Associations with sedentary behavior were evaluated using body mass index in childhood and adolescence and sociodemographic and behavioral variables using hierarchical logistic regression. The overall prevalence of sedentary behavior was 58.1%. Of the 1,716 adolescents evaluated, 50.7% (n = 870) were male. In multivariate analysis, after adjustment for confounding factors, the variables that remained associated with sedentary behavior were: age (14 and over) (OR = 3.51, 95%CI 2.19;5.60);...

The analysis of all hospitalizations for men and women from 20 to 60 years of age was based on the National Healthcare Expenditure Database (SIH-SUS), covering more than 70% of all hospital admissions. Data were for the year 2001. Attributable fraction of hospitalizations associated with diseases related to obesity and overweight was based on the combined risks of United States and European cohorts. The population-attributable fraction for each disease studied was multiplied by values reimbursed to the hospitals and summed to obtain total direct costs. Overall costs of overweight and obesity represent 3.02% of total hospitalization costs for men and 5.83% for women, corresponding to 6.8 and 9.3% of all hospitalization (excluding pregnancy). Diseases associated with overweight and obesity had a significant impact on hospitalizations and economic costs in Brazil, and overall percentages were similar to those from developed countries. Since the nutritional transition is still under way in Brazil, overweight had a higher impact than obesity on disease prevalence and costs.

Data from the population-based National Dietary Survey conducted in 2008-2009. Family per capita income and education levels were categorized into quartiles. Prevalences of inadequate nutrient intakes and excessive intakes of saturated fat and Na were calculated by using the method prescribed by the National Cancer Institute. The Estimated Average Requirement was used as a reference for micronutrient intake. Linear regression models for both the independent and the mutually adjusted associations of education and income with nutrient intakes were tested. Interaction between education and income was tested. Households (n 13 569) selected using a two-stage cluster sampling design. Food records for two non-consecutive days were obtained for 21 003 Brazilian adults (aged 20-59 years). For most of eleven nutrients, the prevalence of inadequate intake declined with increasing income and education leve...

In total, 54 women were randomly assigned to one of two groups for exercise intervention: the control or home-based exercise groups. Weight, waist and hip circumferences, and inflammatory markers were measured at baseline and after 6 and 12 months. Women allocated to the home-based exercise group received a booklet explaining the physical exercises to be practiced at home at least 3 times per week, 40 minutes per session, at low-to-moderate intensity. All participants received dietary counseling aimed at reducing caloric intake by 100-300 calories per day, with a normal distribution of macro-nutrients (26-28% of energy as fat). Clinicaltrials.gov: NCT01206413 RESULTS: The home-based exercise group showed a significantly greater reduction in weight and body mass index at six months, but no difference be...
