“…Moreover, about 86 % of mothers were literate. Recently, researchers in Brazil and Benin have revealed that the lowest mean Hb concentrations were associated with fewer years of maternal schooling (11,38,39) . Moreover, in the present study, the majority of girls had a low consumption frequency of meat, poultry, legumes, vegetables and fruits.…”

Iron deficiency (ID) is the most prevalent micronutrient deficiency in the world, particularly in developing countries. Blood samples and a qualitative FFQ on Feand vitamin C-rich foods were obtained in 180 adolescent girls aged 12 to 17 years living in two boarding schools from south Benin. ID, defined as serum ferritin either ,20 mg/l or 20-50 mg/l, plus two of the following parameters: serum Fe , 11 mmol/l, total iron-binding capacity . 73 mmol/l or transferrin saturation , 20 %, was found in 32 % of subjects. Anaemia (Hb , 120 g/l) was found in 51 % of adolescents, while 24 % suffered from iron-deficiency anaemia (IDA) (ID and Hb , 20 g/l). After adjusting for confounding factors (age, mother's and father's occupation, household size) in a logistic regression equation, subjects having a low meat consumption (beef, mutton, pork) (,4 times/week) were more than twice as likely to suffer from ID (OR 5 2?43; 95 % CI 1?72, 3?35; P 5 0?04). Adolescents consuming less fruits (,4 times/week) also had a higher likelihood of suffering from ID (OR 5 1?53; 95 % CI 1?31, 2?80; P 5 0?03). Finally, subjects whose meat consumption was low were twice as likely to suffer from IDA (OR 5 2?24; 95 % CI 1?01, 4?96; P 5 0?04). The prevalence of ID represents an important health problem in these Beninese adolescent girls. A higher consumption of Fe-rich foods and of promoters of Fe absorption (meat factor and vitamin C) is recommended to prevent ID deficiency in these subjects.

“…a In Brazil, anemia is increasing, unlike malnutrition and hypovitaminosis A. 5 11 54% in Criciúma, Santa Catarina (Southern Brazil), 13 46.3% in Salvador, Bahia 2 and 40.9% in Pernambuco (both in Northeastern), 17 where the prevalence in rural areas (51.4%) was substantially greater than in urban areas (37.8%) in 1997. 17 High prevalences of anemia and its consequences for children's health, and especially for their growth and development, 22 have made anemia an important public health problem, given the diffi culty in implementing effective measures for controlling it.…”

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.

“…10 The fact that anemia is more prevalent in households with lower number of rooms might be associated with factors that contribute to a greater dissemination of infectious diseases and intestinal parasitosis. 13 This is a consequence of confi nement and overpopulation, which, in turn, contribute to the increase in insalubrity. It is known that this process of iron spoliation occurs due to the microhemorrhages that are caused by the parasitosis, and by the reduction in iron absorption and the decrease in hemoglobin production as a result of infections.…”

“…However, the distribution of anemia in the majority of the studied geographical spaces shows that iron defi ciency exceeds the socioeconomic limits, since it occurs in countries that are considered developed. Many studies 3,13 have shown that, the larger the child's family income, the more he/she is protected from anemia, due to the infl uence in the very quality of nutrition. To these authors, although individuals from any stratum are not immune to anemia, families of lower socioeconomic level are subject to a higher risk of developing the disease, and its prevalence tends to be lower in the strata of better socioeconomic level.…”

“…Infants, preschoolers, pregnant women and non-pregnant women of childbearing age are the main risk groups. b Studies have shown a correlation between iron nutritional status and a series of determinants, such as: age, 2,12,19,24 gender, 6 maternal age, housing conditions and birth weight, 20 number of co-inhabitants in the household, 14 mother's level of schooling and per capita income, 13 father's level of schooling, 18 breastfeeding, 15 among others.…”

OBJECTIVE:To estimate the magnitude of the anemia, to analyze the time trends and investigate the factors associated with this disturbance in children in the state of Paraíba, Brazil. METHODS:A cross-sectional survey, of population-based, with 1108 children, aged 6 to 59 months, both sexes in the state of Paraíba. Hemoglobin (Hb) in venous blood was analyzed with an automatic counter. The social-economic and demographic characteristics of children were obtained by questionnaire. Proportions were compared by Pearson's chi-squared test, and the association between hemoglobin concentrations and potential risk factors was tested by regression model Poisson. The time trend of anemia was assessed by the increase/decreased in the prevalence of anemia, using as comparison the prevalence observed in the years 1982, 1992 and 2007. RESULTS:The prevalence of anemia (Hb < 11.0 g/dl) in the state of Paraíba was 36.5% (95%CI 33.7 to 39.3). It was observed that 1.3% (95%CI 0.7 to 1.8) were in severe form (Hb < 7.0 g/dl), 11% (95%CI 9.4 to 13.5) in a moderate form and 87.6% (95%CI 79.1 to 91.2) in the mild form. There was an increase 88.5% in cases of anemia between the years 1982-1992 and stabilization in the prevalence between the years 1992-2007. The analysis adjusted Poisson model showed a greater susceptibility to anemia in children 6 to 24 months of age, those breastfed for six months or more, who co-inhabited with more than four people in the same household and lived in houses with less than fi ve rooms. CONCLUSIONS:The results revealed that anemia remains an important public health problem in the state of Paraíba and despite having been shown an stabilization in the prevalence of anemia between 1992-2007, differently the prevalence observed between 1982-1992, this defi ciency presents in high level, witch requires more effective measures of prevention and control.
