Abstract: the authors describe the concepts, objectives, components and strategic actions that are most frequently recommended for the development of systems of food and nutritional surveillance. the study outlines the importance of a continuous process of data collection, processing and analysis for the follow-up of food and nutritional trends. the system for food and nutritional surveillance could be a valuable instrument for the planning, implementation and analysis of programs and policies of many international agencies of health and nutrition for the year 2000 (unicef/fao/who). the study analyzes the evolution and current situation of the food and nutritional surveillance systems in brazil, and a realtionship is drawn between its main problems (coverage, indicators, usage and analytical capacity) for the consolidation of the process.

Abstract: objective. to determine the prevalence of anemia in children 6-59 months old in pernambuco, a state in northeastern brazil, so as to help guide health and nutrition policies there. methods. in 1997 a representative sample of 777 young children had their hemoglobin concentration measured. the sampling process was in three stages. first, 18 municipalities were randomly selected to represent the state and its three geographic areas (metropolitan region of recife, urban interior, and rural interior). next, using census lists, 45 census sectors were randomly chosen. finally, 777 children aged 6-59 months old were selected. blood was collected by venipuncture, and hemoglobin was measured with a portable hemoglobinometer. in the analysis, prevalence was weighted to reflect the census age distribution. results. the prevalence of anemia among children 6-59 months old was 40.9% for the state as a whole. prevalence in the metropolitan region of recife was 39.6%, and it was 35.9% in the urban interior. the rural interior had the highest prevalence, 51.4%. prevalence was twice as high in children aged 6-23 months as among those 24-59 months old, 61.8% vs. 31.0% (c2 = 77.9, p < 0.001). the mean hemoglobin concentrations in the younger and older age groups were 10.4 g/dl (standard deviation (sd) = 1.5) and 11.4 g/dl (sd = 1.4), respectively. there was no statistically significant difference between the sexes in terms of prevalence. conclusions. this is the first statewide assessment of anemia prevalence among young children in brazil. given the very high prevalence of anemia among the children studied in pernambuco, especially those in the age group of 6-23 months, public health interventions are needed.

Abstract: Objective. To determine the prevalence of anemia in children 6-59 months old in Pernambuco, a state in northeastern Brazil, so as to help guide health and nutrition policies there. Methods. In 1997 a representative sample of 777 young children had their hemoglobin concentration measured. The sampling process was in three stages. First, 18 municipalities were randomly selected to represent the state and its three geographic areas (metropolitan region of Recife, urban interior, and rural interior). Next, using census lists, 45 census sectors were randomly chosen. Finally, 777 children aged 6-59 months old were selected. Blood was collected by venipuncture, and hemoglobin was measured with a portable hemoglobinometer. In the analysis, prevalence was weighted to reflect the census age distribution. Results. The prevalence of anemia among children 6-59 months old was 40.9% for the state as a whole. Prevalence in the metropolitan region of Recife was 39.6%, and it was 35.9% in the urban interior. The rural interior had the highest prevalence, 51.4%. Prevalence was twice as high in children aged 6-23 months as among those 24-59 months old, 61.8% vs. 31.0% (chi2 = 77.9, P < 0.001). The mean hemoglobin concentrations in the younger and older age groups were 10.4 g/dL (standard deviation (SD) = 1.5) and 11.4 g/dL (SD = 1.4), respectively. There was no statistically significant difference between the sexes in terms of prevalence. Conclusions. This is the first statewide assessment of anemia prevalence among young children in Brazil. Given the very high prevalence of anemia among the children studied in Pernambuco, especially those in the age group of 6-23 months, public health interventions are needed.

Abstract: objective: this study assessed the nutritional status of pregnant women by three different methods. methods: a cross sectional study was conducted between january and june 2006 with 992 pregnant women attending a public prenatal care facility. nutritional status was classified according to different assessment methods (rosso nomogram, atalah method and the latin american center for perinatology gestogram). the results were compared with the nutritional status of nonpregnant women in childbearing age in the brazilian northeast and all of brazil. the differences were analyzed by the chi-square goodness of fit test, with a significance level of 5%. results: low weight of pregnant women according to the rosso nomogram was the condition that most contributed to the difference (p<0.001). according to the atalah method, extreme differences were also observed in the prevalences of underweight pregnant women both in the northeast and in all of brazil. in relation to the gestogram of the perinatology latin american center, the greatest prevalence differences also occurred among the underweight: 18% versus 7.4% for the northeast region and 18% versus 6.7% for brazil, although this was the assessment method that came closest to the results of the population being compared. conclusion: nutritional status distribution of pregnant women, assessed by three methods, was different from the nutritional status distribution of the nonpregnant population, both regionally and domestically, especially according to rosso's nomogram, demonstrating the limited use of these instruments. assessment by the perinatology latin american center comes closest to the nutritional status distribution of nonpregnant women.

Abstract: The aim of this protocol is to verify the accuracy of erythrocyte indices and serum ferritin (studied tests) for the diagnosis of functional iron-deficiency in pregnancy using the iron-therapy responsiveness as the gold-standard. This is an ongoing phase III accuracy study initiated in August 2011 and to be concluded in April 2013. The subjects are anemic pregnant women (haemoglobin concentration < 11.0 g/dL) attended at a low-risk prenatal care center in the Northeast of Brazil. The sample size (n 278) was calculated to estimate sensitivity of 90% and 80% of specificity with relative error of 10% and power of 95%. This study has a prospective design with a before-after intervention of 80 mg of daily oral iron during 90 days and will be analyzed as a delayed-type cross-sectional study. Women at the second trimester of pregnancy are being evaluated with clinical and laboratorial examinations at the enrollment and monthly. The 'responsiveness to therapeutic test with oral iron' (gold-standard) was defined to an increase of at least 0.55 Z-score in haemoglobin after 4 weeks of treatment and a total dose of 1200 mg of iron. At the study conclusion, sensitivities, specificities, predictive values, likelihood ratios and areas under the ROC (Receiver Operating Characteristic) curves of serum ferritin and erythrocyte indices (red blood cell count, haematocrit, haemoglobin concentration, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, red blood cell distribution width, reticulocyte count) will be tested. The compliance and adverse effects are considered confounding variables, since they are the main obstacles for the iron-therapy responsiveness.This study protocol shows a new approach on iron-deficiency anemia in pregnancy from a functional point of view that could bring some insights about the diagnostic misclassifications arising from the dynamic physiologic changes during the gestational cycle.Trial registration: WHO Inte

Abstract: based on three cross-sectional studies conducted in the 1970s, 80s, and 90s, an analysis of the nutritional transition in brazil was performed. this analysis found a rapid decrease in the prevalence of childhood malnutrition and an even more rapid increase in adult overweight/obesity. correction of the height deficit was 72% in urban children and 54.4% in rural children. obesity rates doubled or tripled in adult men and women at the extremes of the time series analyzed. excluding the rural northeast, malnutrition prevalence in adult women dropped to acceptable rates (about 5%) starting in 1989. inversely, anemia continued to display a high prevalence, and there is indication of an epidemic trend. the evolution of nutritional status in the brazilian population according to macro-regions and social distribution is reported. the likely factors for the observed changes are analyzed.
