“…Such a similarity in prevalence rates is explained by the remarkable decline in anaemia in the rural areas, thus representing a significant reduction when compared with the urban areas (8) . This reality leads to a more uniform distribution of anaemia among the rural and urban areas of the State, as shown by the loss of significance of geographical area in the regression model of the 2006 survey.…”

“…For the purpose of the sample size calculation of III PESN/PE, an anaemia prevalence rate of 40 % (8) , an error rate of 3?1 % and a 95 % confidence level were used. In both surveys, an additional 10 % rate was considered to offset any losses, resulting in representative samples of 777 and 993 children, respectively, in II PESN/PE and III PESN/PE.…”

Objective: To analyse the trends and factors associated with anaemia in 6-to 59-month-old children in Northeast Brazil. Design: Cross-sectional study assessed information from the second and third Pernambuco State Health and Nutrition Surveys carried out in 1997 and 2006. A multiple regression analysis was performed from a conceptual model addressing biological and socio-economic factors, housing and sanitation conditions, maternal factors, health care and nutrition, consumption, morbidity and nutritional status. Poisson's regression with robust variance was used. Setting: Pernambuco, Brazil. Subjects: A total of 777 and 993 children, respectively, in the second and third Pernambuco State Health and Nutrition Surveys. Results: The prevalence of anaemia (Hb , 11 g/dl) decreased by 19?3 % (40?9 % down to 33?0 %) between surveys. Maternal education level (less than 8 years in school), households ranked in the lowest environmental index tertile and children between 6 and 23 months of age were the variables common to the final models in the surveys of 1997 and 2006. Elements like living in rural areas, household income less than two minimum official wages and low birth weight were still present in the final model of the 1997 survey. Households ranked in the lowest economic index tertile were associated with anaemia in the model of the 2006 survey. Conclusions: The study results are quite encouraging from the perspective of reducing the prevalence of anaemia. Maternal education level, environmental conditions and child age were determinant factors in both surveys, and economic factors were determinant in 2006.

“…The sample calculation for each geographical area assumed an error of 3.7% and anemia prevalence of 40% for the state of Pernambuco, 17 with a confi dence interval of 95%. The whole population of children under the age of fi ve years in each geographical area was considered, c and 10% was added to the sample size to compensate for possible losses.…”

OBJECTIVE:To estimate the prevalence of anemia and to identify its associated factors in children aged 6-59 months. METHODS:This was a cross-sectional study on data from the Third Health and Nutrition Survey of the State of Pernambuco, Northeastern Brazil, with a representative sample of 1,403 children from urban and rural areas. Anemia was diagnosed by means of hemoglobin assays. Multivariate analysis was performed though a hierarchical model, using robust-variance Poisson regression to estimate the prevalence ratio as a function of the following variables: biological factors, morbidity, child nutritional state, socioeconomic factors, housing, sanitation and maternal factors. RESULTS:The weighted prevalence of anemia was 32.8% overall: 31.5% in urban areas and 36.6% in rural areas. In urban areas, anemia was signifi cantly associated with maternal education, consumer goods, number of children less than fi ve years old in the home, drinking water treatment, maternal age, maternal anemia and the child's age. In rural areas, only maternal age and the child's age were signifi cantly associated with anemia. CONCLUSIONS:The prevalence of anemia in children in Pernambuco was similar in urban and rural areas. The factors associated with anemia that are presented here should be taken into consideration in planning effective measures for its control.

Prevalence of anemia in children 6-59 months old in the state of Pernambuco, Brazil

Abstract: 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.
